 1 | = A Groovy Light Table client - Not dead (yet)
 2 | Magnus Rundberget
 3 | 2015-01-25
 4 | :jbake-type: post
 5 | :jbake-status: published
 6 | :jbake-tags: lighttable, groovy, gradle, clojurescript
 7 | :id: gr_lt_status_jan2015
 8 | 
 9 | == Background
10 | In 2014 I blogged about the process of evolving a groovy(/gradle) plugin for Light Table from scratch.
11 | 
12 | .Posts so far:
13 | * link:/blog/2014/gr_lt_part1.html[A Groovy Light Table client - Step 1: Connecting the client]
14 | * link:/blog/2014/gr_lt_part2.html[A Groovy Light Table client - Step 2: Evaluating Code]

17 | * link:/blog/2014/gr_lt_part5.html[A Groovy Light Table client - Step 5: Gradle dependencies in Light Table with dagre-D3]
18 | 
19 | I even did a link:/blog/2014/groovy_repl.html[screen cast] showing off some of the features so far.
20 | 
21 | 
22 | 
23 | == So what happened ?
24 | 
25 | After the summer holidays my Open Source mojo was drained, I needed a break and I went into uphill cycling mode.
26 | 
27 | 
28 | === Light Table doubts
29 | First of all. I haven't given up on Light Table I somehow even feel strongly obliged to hang in there longer
30 | than most people given that I've contributed. I still use Light Table, actually more than ever because I'm currently
31 | hacking on a clojure/clojurescript project.
32 | 
33 | In October the founder of Light Table annouced Eve and released this http://www.chris-granger.com/2014/10/01/beyond-light-table/[blog post]
34 | Obviously there was initial fears that this would be the end of Light Table. However 3 of the most active contributors
35 | to Light Table stepped up. There was a lot of visible activity initially (proper spring cleaning of the issues log).
36 | However visible activity from Light Table has been in steady decline and the last release was 21. november of last year.
37 | 
38 | 
39 | I believe they are working on moving from node-webkit to atom shell, the layout system is being revised. There is also a hack night planned
40 | in a few days time.
41 | 
42 | I guess I just wished someone stepped up and outlined a clear road-map for Light Table and that
43 | a steady stream of releases towards a version 1.0 started coming out :)
44 | 
45 | 
46 | === Possibilites for further developments
47 | Great things are happening with gradle I believe in terms of performance and also in terms of whats possible
48 | to achieve with the Tooling API. This opens up a whole range of oportunities to provide IDE support for languages that gradle supports.
49 | 
50 | The groovy and gradle parts of the currenty groovy plugin should probably be split with a generic gradle
51 | plugin and specific language plugins (scala, java...) depending on that.
52 | 
53 | 
54 | .How about things like ?:
55 | * Continuous unit testing - utilizing gradle builds incremental nature and the coming watcher tasks.
56 | Couple that with showing results inline in Light Table
57 | * Compilation - Same story here, show compilation errors inline
58 | * run webapp - Run apropriate gradle task to start your webapp and fire up a browser window inline in lighttable
59 | , maybe even hook it up with a browser debug/repl connection
60 | 
61 | 
62 | 
63 | === Help needed
64 | I'd love to hear if anyone has actually used the plugin and if so which parts of it.
65 | 
66 | I'm currently fully engaged in a clojure/clojurescript project, which takes all of my day time and quite a few evenings.
67 | It puts me in a better shape to contribute to Light Table, but currently leaves me little time to do so.
68 | 
69 | .That might change though, but I guess I need 2 things to happen before I pick up work on this plugin:
70 | . Some visible progress from Light Table to show that it's intending to survive
71 | . Hopefully someone feels inspired to help contribute progressing the plugin (pull requests are welcome)
72 |

 1 | = A Groovy Light Table client - Step 3: Running out of quick wins
 2 | Magnus Rundberget
 3 | 2014-05-12
 4 | :jbake-type: post
 5 | :jbake-status: published
 6 | :jbake-tags: lighttable, groovy, clojurescript
 7 | :id: gr_lt_part3
 8 | 
 9 | 
10 | == Background
11 | 
12 | This is the third post in my series "A Groovy Light Table client". A blog series about steps I take when trying to build a Groovy plugin for Light Table.
13 | 
14 | == Running out of quick wins
15 | 
16 | After 0.0.2 of the plugin was released I was pretty happy. I had something that I could actually use as an alternative Groovy Console. However I was keen to keep up the flow so I figured I would try to implement an autocomplete feature. The task proved rather daunting. Not so much from the Light Table side of things, but rather from the Groovy side. First I tried to see if I could reuse anything from GroovySh, but that didn't look to promising. After that I tried to get my head around whether I could somehow reuse something from IntelliJ or Eclipse. I failed to see the light so I gave up that endeavour. Secondly I tried to see if there was an easy way to provide an inline documentation feature. Sadly I couldn't find much reusable and something with a small foot print here either. Someone should make a REST based doc search feature for Groovy Docs one day !
17 | 
18 | I turned my attention to a couple of other plugins that I thought would be useful for Light Table. I created a Buster.JS plugin https://github.com/busterjs/lt-instabuster[InstaBuster] for easily running JavaScript tests. I also created a snippets/code templates plugin https://github.com/rundis/lt-snippets[lt-snippets] and some snippet collections, among them a small collection of https://github.com/rundis/lt-groovy-snippets[groovy snippets].
19 | 
20 | There is just no way I could ever compete with the mainstream IDE's, but then again that was never really the original intention. But even with limited capacity it should still be possible to provide useful groovy support and maybe even something fairly unique within the super hackable framework of Light Table.
21 | 
22 | == A (small) step towards a Groovy REPL
23 | 
24 | After working with Light Table and the Clojure/ClojureScript REPL I have grown very fond of that exploratory nature of working. Is there anything I could do with the plugin to give a more REPL like feel ? Well a small but helpful step would be to be able to remember what I previously have evaluated ...
25 | 
26 | === Groovy Bindings
27 | 
28 | A simple but still useful mechanism would be to cache bindings from script execution between evals.
29 | [source,groovy]
30 | ----
31 | // from the evalGroovy method
32 | def evalResult = scriptExecutor.execute(data.code, clientSessions.get(currentClientId))
33 | clientSessions.put(currentClientId, evalResult.bindings)
34 | ----
35 | 
36 | Each editor in Light Table gets it's own unique Id. So I just created a simple cache "ClientSessions" that hold a map of binding variables, mapped my that Id. When executing a script the current binding variables are applied to the script and after the script has executed the resulting binding variables are added/replaced in the cache. Dead simple really.
37 | 
38 | === Clearing bindings - Light Table
39 | 
40 | I figured it would be handy to be able to clear any stored bindings. So a new command and behaviour was created in Light Table
41 | 
42 | [source,clojure]
43 | ----
44 | ;; Behavior for clearing bindings
45 | (behavior ::on-clear-bindings
46 |           :desc "Clear cached bindings for this editor"
47 |           :triggers #{:on.clear.bindings}
48 |           :reaction (fn [editor]
49 |                       (let [info (:info @editor)
50 |                             cl (eval/get-client! {:command :editor.clear.groovy
51 |                                                     :origin editor
52 |                                                     :info info
53 |                                                     :create try-connect})]
54 |                           (clients/send cl
55 |                                         :editor.clear.groovy info
56 |                                         :only editor))))
57 | 
58 | ;; Command that allows a new keyboard bindable action for invoking the behaviour above
59 | (cmd/command {:command :clear-bindings
60 |               :desc "Groovy: Clear bindings for current editor"
61 |               :exec (fn []
62 |                       (when-let [ed (pool/last-active)]
63 |                         (object/raise ed :on.clear.bindings)))})
64 | ----
65 | 
66 | The command retrieves the currently active editor and triggers the behaviour. The behaviour retrieves a client connection (or creates one if one shouldn't exist) and calls the server (groovy).
67 | [source,clojure]
68 | ----
69 | // Wiring up the behaviour in groovy.behaviors
70 | :editor.groovy [:lt.plugins.groovy/on-eval
71 |                      :lt.plugins.groovy/on-eval.one
72 |                      :lt.plugins.groovy/on-clear-bindings
73 |                      :lt.plugins.groovy/groovy-res
74 |                      :lt.plugins.groovy/groovy-err
75 |                      [:lt.object/add-tag :watchable]]
76 | ----
77 | 
78 | The final piece of the puzzle from the Light Table side is to attach the behavior to the :editor.groovy tag. This enables the behavior to be available from any editor that is tagged with this tag.
79 | 
80 | === Clearing bindings - Groovy
81 | [source,groovy]
82 | ----
83 | // The command dispatch got a new command
84 | case "editor.clear.groovy":
85 |    clientSessions.clear(currentClientId)
86 |    break;
87 | ----
88 | The code above will just nuke any stored binding variables.
89 | 
90 | == Conclusions
91 | 
92 | A tiny step that allows you to eval groovy expressions step by step. Anything that results in a binding is stored between evals. Obviously it's a bit limited in that you'll run into the familiar trap of trying to use def and be surprised(/annoyed) that it won't remember that or if you define a class it won't remember that either. It's probably possible to cater for some of these traps, but maybe not within the realms of a quick win.
93 | 
94 | Anyways the end result is Version 0.0.3 !
95 | 
96 | Next steps
97 | 
98 | Firstly there is a Screencast brewing. After that I think a Light Table Gradle plugin is coming before the Groovy plugin gets any further updates. A pluggable Gradle plugin would enable the Groovy plugin to quite easily get the class path for you project. This would allow you to  explore your projects code in a REPL (-like) way. Exploratory testing FTW !

  1 | = Javascript testing in your JVM projects using Gradle and BusterJS
  2 | Magnus Rundberget
  3 | 2013-08-19
  4 | :jbake-type: post
  5 | :jbake-status: published
  6 | :jbake-tags: gradle, groovy, javascript, buster, screencast
  7 | :id: buster_plugin
  8 | 
  9 | 
 10 | == Introduction
 11 | When I first started looking at testing in javascript land a while back I quickly felt lost in space.
 12 | 
 13 | .Filled with questions like;
 14 | * which framework(s) to choose ?
 15 | * how do I get framework x to work from my IDE ?
 16 | * more importantly how to I manage to include the javascript tests in my CI builds ?
 17 | * how can I avoid repetitive setup pain across projects ?
 18 | * why is it such a hassle getting started ?
 19 | 
 20 | I can't say I have answered any of the questions above fully, but I have taken some strides in the right direction.
 21 | 
 22 | == Buster.JS
 23 | http://docs.busterjs.org/en/latest/[Buster] is a flexible and modularized framework for writing and running your JavaScript tests.
 24 | There are others out there, but from what I could gather and based on advice from my frontend wizard colleagues I decided to give it a good go. It's still in beta, but from my experiences so far its more than mature enough for proper use in projects.
 25 | 
 26 | === A few important aspects about Buster.JS:
 27 | Tests are run in real browsers (phantomjs for headless). No emulation bull
 28 | You can run tests in multiple browsers in parallell
 29 | Its really really fast
 30 | Write tests in the fashion that suits you (xUnit or spec)
 31 | Nice assertion library and integrated with Sinon.JS (powerful stubbing and spying)
 32 | ... and lots more
 33 | 
 34 | == Gradle buster plugin
 35 | For my jvm project builds I use Gradle. Maven and Ant projects that spend time with me a few weeks tend to find themselves converted. So I set out to create a buster plugin for gradle, aptly named gradle-buster-plugin. Still early days, but already it has started to prove quite valuable.
 36 | 
 37 | .The plugin has two high-level goals;
 38 | * Allow you to easily run javascripts as part of your CI builds
 39 | * Provide you with a smooth development experience by adding value on top of whats already present in Buster.JS.
 40 | 
 41 | The homepage for the pluging is here: https://github.com/rundis/gradle-buster-plugin
 42 | 
 43 | == What do I have to do ? (aka getting started)
 44 | === Installing preconditions
 45 | * Install node.js/npm - Mac: $ brew install node
 46 | * Install Buster.JS  - $ npm install buster -g
 47 | * Install Phantom.JS  - Mac: $ brew install phantomjs
 48 | 
 49 | === Set up the buster plugin in your gradle config
 50 | [source,groovy]
 51 | ----
 52 | buildscript {
 53 |     repositories { jcenter() }
 54 |     dependencies {
 55 |         classpath  'org.gradle.buster:gradle-buster-plugin:0.2.4.1'
 56 |     }
 57 | }
 58 | 
 59 | apply plugin: 'war' // just assuming you have a war project
 60 | apply plugin: 'buster'
 61 | 
 62 | build.dependsOn busterTest // hook up javascript task in the build
 63 | ----
 64 | 
 65 | 
 66 | === Set up a buster.js configuration file
 67 | [source,javascript]
 68 | ----
 69 | var config = module.exports;
 70 | 
 71 | config["Sample JSTests"] = {
 72 |     environment: "browser",
 73 | 
 74 |     libs: ["src/main/webaapp/js/libs/jquery-1.10.2.js"],
 75 |     sources: ["src/main/web-app/js/app/**/*.js"],
 76 |     tests: ["src/test/js/**/*-test.js"]
 77 | };
 78 | ----
 79 | 
 80 | === Sample unit
 81 | 
 82 | So you could create a file like src/main/webapp/js/app/dummy-service.js
 83 | [source,javascript]
 84 | ----
 85 | var myapp = this.myapp || {};
 86 | myapp.services = app.services || {};
 87 | (function () {
 88 |     myapp.services.DummyService = function (my) {
 89 |         my.listTodos = function(success, error) {
 90 |             $.get('/todos/list')
 91 |                .done(function(data) {
 92 |                   success(data);
 93 |                })
 94 |                .fail(function(jqXHR, textStatus, errorThrown) {
 95 |                   error("Error getting todos")
 96 |                });
 97 |         };
 98 |         return my;
 99 |     }(myapp.services.DummyService || {});
100 | }());
101 | ----
102 | 
103 | === Sample unit test
104 | Create a corresponding unit test in src/test/js/app/dummy-service-test.js
105 | [source,javascript]
106 | ----
107 | (function () {
108 |     buster.testCase("DummyService", {
109 |         setUp: function() {
110 |             this.service = myapp.services.DummyService;
111 |             this.server = sinon.fakeServer.create();
112 |             this.success = this.spy();
113 |             this.error = this.spy();
114 |         },
115 |         tearDown: function () {
116 |             this.server.restore();
117 |         },
118 |         "should successfully list todos": function () {
119 |             this.service.listTodos(this.success, this.error);
120 |             this.server.requests[0].respond(
121 |                 200,
122 |                 { "Content-Type": "application/json" },
123 |                 JSON.stringify([{ id: 1, text: "Provide examples", done: true }])
124 |             );
125 | 
126 |             assert.calledOnce(this.success);
127 |         },
128 |         "should invoke error callback on errors": function () {
129 |             this.service.listTodos(this.success, this.error);
130 |             this.server.requests[0].respond(
131 |                 500,
132 |                 { "Content-Type": "application/json" },
133 |                 JSON.stringify([{ id: 1, text: "dummy", done: true }])
134 |             );
135 | 
136 |             assert.calledOnce(this.error);
137 |         }
138 |     });
139 | }());
140 | ----
141 | 
142 | 
143 | 
144 | === Running the tests locally
145 | [source,bash]
146 | ----
147 | $ gradle busterTest
148 | ----
149 | 
150 | Test results are found in : build/busterTest-results/bustertests.xml
151 | 
152 | 
153 | Autotesting
154 | When doing your tdd cycles its quite useful to use the autotest feature (kinda like infinitest).
155 | [source,bash]
156 | ----
157 | $ gradle busterAutoTest
158 | ----
159 | 
160 | 
161 | Will leave the server running and listen for file changes in the patterns specified by the buster.js file above. So if I change the test or unit above a test run will automatically be fired off and results reported to the console. Its pretty fast so you should be able to keep a good flow going !
162 | Just do Ctrl + C to kill the autotesting.
163 | 
164 | Multiple browsers
165 | Its quite easy to set up just see the readme for the plugin
166 | 
167 | 
168 | CI Server
169 | Obviously you will need to set up the preconditions. If you're server isn't headless you have the option of testing with a few proper browsers(firefox and chrome on linux, safari if your server is mac... which I doubt).
170 | 
171 | 
172 | == Conclusion
173 | Its certainly not perfect, but with the above you have a pretty good start. Once you get over the hurdle of setting up the preconditions it really is quite pleasant to work with. You should be amazed by the performance of the tests runs if you are from a jvm background.
174 | What about IDE integration ? With the autotest feature I can't say I have missed it much. I have my IDE and a visible console available and get instant feedback on saves in my IDE.
175 | 
176 | Smooth !
177 |

  1 | = Bootifying my ring app

  5 | :jbake-status: published
  6 | :jbake-tags: clojure, boot.clj
  7 | :id: bootify_ring
  8 | 
  9 | == A little background
 10 | A few weeks back I noticed a tweet about https://github.com/boot-clj/boot[boot-clj]. This weekend I finally had some time to look into whether it could
 11 | be a viable alternative to https://github.com/technomancy/leiningen[Leiningen] for our apps or not.
 12 | We have a couple of ring based apps running as uberjars, so I decided to try to make a boot build for one of the projects. For the purpose of this blogpost however
 13 | I've created a sample app. Source available on https://github.com/rundis/boot-sample[github]
 14 | 
 15 | == Why bother with an alternative when there is Leiningen ?
 16 | I haven't been in the clojuresphere all that long.
 17 | I do have a history as java and groovy developer and have been through a history of using http://ant.apache.org/[ant],
 18 | http://maven.apache.org/[maven] and lately https://www.gradle.org/[gradle] for my builds.
 19 | In terms of development experience Leiningen is definately a step up from all of them. However I feel Leiningen has left me longing
 20 | as soon as my builds have become a bit more elaborate (testing javascript, transpiling, create artifacts, upload to repo, run migrations
 21 | deploy to different environments etc). I'm sure all of this is achievable with Lein, but is it really architected to excel for that purpose ?
 22 | TBH I'd love to see gradle get some serious clojure love, but it doesn't seem to be coming anytime soon. Maybe boot will be my next build tooling love :)
 23 | 
 24 | .Reading up a bit on boot checked a few boxes for some of my longings though:
 25 | * Your build doesn't have to be all declarative
 26 | * Sensible abstractions and libraries to allow you to compose and extend your build using the full power of clojure
 27 | * Compose build pipelines somewhat similar to how you would compose middlewares in ring
 28 | * Task is the fundamental building block
 29 | * Tasks typically works on immutable filesets (files treated as values, you never touch the filesystem directly yourself !)
 30 | * Possibility of complete classpath isolation at task level
 31 | * Great repl and commandline support.
 32 | * ... and surely a lots more

104 | Hey. Hang on. There is no main method here, how can the java -jar command work without one ?
105 | Well, because the ring plugin creates one for us.

126 | 
127 | That's useful to know in case boot-clj doesn't happen to have a ring task that does something similar.
128 | 
129 | 
130 | === Boot me up
131 | 
132 | Boot comes with a range of predefined tasks that I can compose to get quite close to the Leiningen build above.
133 | I'll focus on getting that uberjar up and running.
134 | 
135 | I could have done it all on the command line or in the boot repl, but lets just be a little declarative (still functions don't worry!).

164 | ----
165 | 
166 | <1> To bundle your sources in the output jar, you have to specify src as a resource-path. A small gotcha there.
167 | <2> We need to aot our core.clj namespace so that java -jar can invoke it's main method
168 | <3> We need to help java -jar with the location of our main class in the jar
169 | 
170 | However you might remember from above that there is no main method in core.clj.
171 | So the last piece of the puzzle is to add one. It't not that hard.

198 | 
199 | [NOTE]
200 | ====
201 | At the time of writing there was a regression in boot that caused aot to fail.
202 | I needed to build boot from source, should be fixed in the next release though.

214 | [source,bash]
215 | ----
216 | boot build
217 | java -jar target/boot-sample-0.1.0.jar
218 | ----
219 | 
220 | 
221 | === All is well then ?
222 | Unfortunately not quite. For uberjar projects it seems boot-clj at the time of writing has some serious
223 | performance challenges.
224 | 
225 | .On my machine generating the uberjar takes:
226 | * Leiningen : 12 seconds
227 | * boot-clj  : 46 seconds !
228 | 
229 | 
230 | It's not like Leiningen is lightning fast in the first place. But for this scenario boot just doesn't cut it.
231 | I reported an https://github.com/boot-clj/boot/issues/94[issue] and got prompt responses from the developers
232 | which can only be a good sign.
233 | 
234 | 
235 | 
236 | 
237 | == Concluding remarks
238 | My initial question of whether or not I feel we could use boot for our current projects gets a thumbs down for now.
239 | 
240 | I think boot-clj carries a lot of promise and have some really great ideas. It's going to be interesting to
241 | see if boot-clj becomes a viable alternative to leiningen. I suppose a porting and/or interop story with lein
242 | and lein plugins might be needed in addition to maturing both the model and obviously its performance characteristics.
243 | 
244 | I'm certainly keen on trying it out more. I might try out the clojurescript support next and maybe churn out some custom tasks
245 | just for fun.

  1 | = Securing Clojure Microservices using buddy - Part 1: Creating Auth Tokens
  2 | Magnus Rundberget
  3 | 2015-01-27
  4 | :jbake-type: post
  5 | :jbake-status: published
  6 | :jbake-tags: clojure, buddy, security
  7 | :imagesdir: /blog/2015/
  8 | :icons: font
  9 | :id: buddy_auth_part1
 10 | 
 11 | 
 12 | == Disclaimer
 13 | [WARNING]
 14 | ====
 15 | There is much more to securing web apps and microservices than just authentication and authorization.
 16 | This blog series will almoust exclusively focus on those two aspects.
 17 | ====
 18 | 
 19 | == Introduction
 20 | Lets say you have decided to go down the microservices path with Clojure. How would
 21 | you go about implementing authentication and authorization for your various apps and services ?
 22 | 
 23 | In this blog series I'll take you through my stumblings through how you might address
 24 | some of the concerns. At this point I have no idea how it might turn out, but I'm pretty
 25 | sure I'll learn quite a bit along the way.
 26 | 
 27 | 
 28 | == Sample architecture
 29 | To illustrate various aspects I'll be using the following sample high-level architecture
 30 | as a starting point. It's just an sketch,  so don't get too hung up on the dependency arrows, that might change.
 31 | 
 32 | image::auth_fun.png[]
 33 | 
 34 | You'll find the evolving code examples at https://github.com/rundis/acme-buddy. A tag will be created
 35 | for each blog posting.
 36 | 
 37 | 
 38 | == Initial selection of technologies
 39 | 
 40 | The most known and used library in clojure for securing your ring webapps is https://github.com/cemerick/friend[friend].
 41 | To my knowledge it's a great library, and you should seriously consider using it for your apps as well.
 42 | 
 43 | A little while back I did a small spike on using friend and http://clojure-liberator.github.io/liberator/[liberator]. Liberator
 44 | is a super library for rest enabling your applications/services. I came across the blog post http://sritchie.github.io/2014/01/17/api-authentication-with-liberator-and-friend/[API Authentication with Liberator and Friend].
 45 | I tried to implement something similar but couldn't quite get it working and I have to admit I had problems grocking what
 46 | was actually going on.
 47 | 
 48 | So for this blog series I decided to start off with something less opinionated. Hopefully that will enable me to understand
 49 | more about the concerns involved. In https://github.com/funcool/buddy[buddy] I found an a la carte menu of building blocks
 50 | that looked very promising as a starting point.
 51 | 
 52 | 
 53 | == Token based authentication
 54 | 
 55 | The goal for this first post is to create a service that allows a caller to authenticate a user by credentials
 56 | and receive an authentication token upon successful authentication. That token can then be used by services and apps
 57 | to authenticate and authorize requests for the duration of defined lifespan for the token. The service
 58 | will be implemented in the acme-auth service app.
 59 | 
 60 | 
 61 | TIP: http://stackoverflow.com/questions/1592534/what-is-token-based-authentication[What is token based authentication ?]
 62 | 
 63 | 
 64 | === Database
 65 | For this sample app we'll use a plain old boring rdbms. The schema will be as follows.
 66 | 
 67 | image::acme_user_db.png[]
 68 | 
 69 | 
 70 | === Password hashing
 71 | We need to store our passwords securely hashed in the user table. Buddy provides https://github.com/funcool/buddy-hashers[buddy-hashers].
 72 | 
 73 | 
 74 | .Adding a user
 75 | [source,clojure]
 76 | ----
 77 | (ns acme-auth.service
 78 |   (:require [buddy.hashers :as hs]
 79 |             [acme-auth.store :as store]))
 80 | 
 81 | (defn add-user! [ds user]
 82 |   (store/add-user! ds (update-in user [:password] #(hs/encrypt %))))
 83 | 
 84 | ----
 85 | 
 86 | hs/encrypt - Hashes the password using bcrypt+sha512 (default, others available)
 87 | 
 88 | .Authenticating a user
 89 | [source,clojure]
 90 | ----
 91 | (defn auth-user [ds credentials]
 92 |   (let [user (store/find-user ds (:username credentials))
 93 |         unauthed [false {:message "Invalid username or password"}]]
 94 |     (if user
 95 |       (if (hs/check (:password credentials) (:password user))            // <1>
 96 |         [true {:user (dissoc user :password)}]                           // <2>
 97 |         unauthed)
 98 |       unauthed)))
 99 | ----
100 | <1> Verify provided plain text password credential against the hashed password in the db
101 | <2> You probably don't want to ship the password in the token !
102 | 
103 | TIP: Bcrypt is intentionally relatively slow. It's a measure to help prevent brute force attacks.
104 | 
105 | === Creating a signed token
106 | With the user store in place we can turn our attention to creating our (signed) token. Buddy provides us with https://github.com/funcool/buddy-sign[buddy-sign].
107 | We could have opted for a http://en.wikipedia.org/wiki/Hash-based_message_authentication_code[HMAC] based algorithm,
108 | but we'll take it up one notch and use an algorithm that requires a public/private key-pair.
109 | Not only that, but we'll serialize our token content in a json format following the https://tools.ietf.org/html/draft-ietf-jose-json-web-signature-41[jws]
110 | draft spec.
111 | 
112 | 
113 | https://github.com/rundis/acme-buddy/tree/master/acme-auth[acme-auth] will own the private key and use that for signing
114 | whilst the other apps will have the public key for unsigning the token.
115 | 
116 | 
117 | 
118 | 
119 | ==== Creating a key-pair
120 | You'll be asked to enter a passphrase in both steps below. Keep it safe !
121 | 
122 | [source,bash]
123 | ----
124 | openssl genrsa -aes128 -out auth_privkey.pem 2048
125 | ----
126 | 
127 | [NOTE]
128 | ====
129 | You should probably use something stronger than -aes128. You'll need to fiddle with your JVM, but might be worth it
130 | unless it's important for you that your government agencies have access to decrypting your token signatures.
131 | ====
132 | 
133 | [source,bash]
134 | ----
135 | openssl rsa -pubout -in auth_privkey.pem -out auth_pubkey.pem
136 | ----
137 | 
138 | ==== Signing
139 | 
140 | [source,clojure]
141 | ----
142 | (ns acme-auth.service
143 |   (:require [buddy.sign.generic :as sign]
144 |             [buddy.sign.jws :as jws]
145 |             [buddy.core.keys :as ks]
146 |             [clj-time.core :as t]
147 |             [clojure.java.io :as io]))
148 |

151 |   (ks/private-key
152 |    (io/resource (:privkey auth-conf))
153 |    (:passphrase auth-conf)))
154 | 
155 | (defn create-auth-token [ds auth-conf credentials]
156 |   (let [[ok? res] (auth-user ds credentials)
157 |         exp (-> (t/plus (t/now) (t/days 1)) (jws/to-timestamp))]   // <2>
158 |     (if ok?
159 |       [true {:token (jws/sign res                                  // <3>
160 |                               (pkey auth-conf)
161 |                               {:alg :rs256 :exp exp})}]
162 |       [false res])))
163 | ----
164 | <1> Helper function to read the private key we generated above
165 | <2> Sets a timestamp for when the token expires
166 | <3> Creates a signed token
167 | 
168 | .The token consists of 3 parts concatenated using "."
169 | * Base64 encoded string with header data (algorithm and other optional headers you might have set)
170 | * Base64 encoded json string with your message (claims in jws speak). Expiry ie. :exp is also a claim btw.
171 | * Base64 encoded MAC (Message Authentication Code) signature for our message (header + claims)
172 | 
173 | With that knowledge in mind, you see why it might be a good idea to leave the password out of the token (even though it would have been the hashed pwd we're talking about).
174 | 
175 | 
176 | === Exposing our service
177 | 
178 | .handler
179 | [source,clojure]
180 | ----
181 | (defn create-auth-token [req]
182 |   (let [[ok? res] (service/create-auth-token (:datasource req)
183 |                                            (:auth-conf req)
184 |                                            (:params req))]
185 |     (if ok?
186 |       {:status 201 :body res}
187 |       {:status 401 :body res})))
188 | ----
189 | 
190 | .Ring / Compojure wrap-up
191 | [source,clojure]
192 | ----
193 | 
194 | (defroutes app-routes
195 |   (POST "/create-auth-token" [] handlers/create-auth-token))
196 | 
197 | 
198 | (defn wrap-datasource [handler]
199 |   (fn [req]
200 |       (handler (assoc req :datasource (get-ds)))))
201 | 
202 | (defn wrap-config [handler]
203 |   (fn [req]
204 |     (handler (assoc req :auth-conf {:privkey "auth_privkey.pem"
205 |                                     :passphrase "secret-key"}))))
206 | 
207 | (def app
208 |   (-> app-routes
209 |       wrap-datasource
210 |       wrap-config
211 |       wrap-keyword-params
212 |       wrap-json-params
213 |       wrap-json-response))
214 | ----
215 | 
216 | === Invoking
217 | [source,bash]
218 | ----
219 | curl -i -X POST -d '{"username": "test", "password":"secret"}' -H "Content-type: application/json" http://localhost:6001/create-auth-token
220 | ----
221 | 
222 | Would yield something like:
223 | [source,javascript]
224 | ----
225 | {"token":"eyJ0eXAiOiJKV1MiLCJhbGciOiJSUzI1NiJ9.eyJ1c2VyIjp7InVzZXItcm9sZXMiOlt7InJvbGUtaWQiOjEwLCJhcHBsaWNhdGlvbi1pZCI6MTB9LHsicm9sZS1pZCI6MTEsImFwcGxpY2F0aW9uLWlkIjoxMH1dLCJ1c2VybmFtZSI6InRlc3QiLCJpZCI6MX0sImV4cCI6MTQyMjMxNDk3MH0.bKB3fh2CcPWqP85CK18U_IITxkRce8Xuj8fZGvhqjAaq1dWeiDMKOAGfSlg6GGJi-CrRepMaLOEfAVN23R7yoYb543wgm1Tv_pOYuNQ02tYRQMRJXSxVKS1m9zMEWlszLVet8Q3kfrLBaOxjdvjSp8exjsPeOcfCaqdcXPn9mwWSz0X8k1iaLbnY2fRL0mWbbG8rz4bSUSE0KX0xnKH3LqrtJcZE3BDHSr7tVqaxcHaFt4ivRpk3EYBzMtwRSCQ4jwAMibsh1XhvJMo4QeDwil-et70qJMV5XCJOsAr3SF4FVlNeUsNx2Aj1lORGIN7c8xKq-MDaTaGYV2O7L_0mGA"}
226 | ----
227 | 
228 | 
229 | Unsigning the token is quite similar to the signing. However when unsigning you must have the
230 | public key we generated earlier.
231 | 
232 | 
233 | For the token above, the claims part of the message would look like this:
234 | [source,javascript]
235 | ----
236 | {"user":{"user-roles":[{"role-id":10,"application-id":10},
237 |                        {"role-id":11,"application-id":10}],
238 |          "username":"test",
239 |          "id":1},
240 |  "exp":1422314970}
241 | ----
242 | 
243 | 
244 | == Summary
245 | We have created a small clojure app with a user database and a rest service that authenticates a
246 | user and returns a signed token with information about the user and his/her role+app/service authorizations.
247 | We've briefly covered password hashing and message signing using buddy.
248 | 
249 | The auth-token service will serve as a building block for the next step. How do we make use of token
250 | for authentication and authorization purposes in the acme-webstore ? That's the topic of my next blog
251 | post in this series. Stay tuned !

 11 | == Background
 12 | 
 13 | This is the fourth post in my series "A Groovy Light Table client". A blog series about steps I take when trying to build a Groovy plugin for Light Table.
 14 | 
 15 | == Initial ponderings
 16 | 
 17 | Gradle ships with a Tooling API that makes it fairly easily to integrate with your Gradle projects. Initially I thought that Gradle integration should be a separate plugin that other jvm language plugins could depend on, starting with the Groovy plugin. However after much deliberation I decided to start out with bundling the gradle integration with the Groovy plugin. There is certainly a degree of selecting the easy option to that decision. However I still consider the integration exploratory and I'm not sure how it will pan out. I've settled for a strategy of keeping it logically fairly separate, with a mind to separating gradle specifics out to its own plugin when things become clearer.
 18 | 
 19 | == Classpath Integration for Groovy "REPL"
 20 | 
 21 | In part 3 I talked about some REPL like features where variables that result in bindings are stored in a editor session and used as input to the next evaluation. Since then I've also added the feature of caching method definitions (albeit as closures so I'm sure there are gotchas to that approach as well).
 22 | 
 23 | Anyways wouldn't it be nice If I could also explore my project classes and my projects third party library dependencies in a REPL like fashion ? Hence the idea of providing a Gradle integration. With the Tooling API I should be able to retrieve a class path. So this is where i started.
 24 | Before anyone potentially asking; I will not bother with maven or ant at any point in time, I'll leave that to someone else.
 25 | 
 26 | === Retrieving the class path as a list from a Gradle project
 27 | 
 28 | [source,groovy]
 29 | ----
 30 | // Step 1: Connecting to project
 31 | def con = GradleConnector.newConnector()
 32 |   .forProjectDirectory(projectDir)
 33 |   .connect()
 34 | 
 35 | // Step 2: Get hold of a project model, for now a IdeaModel provides what we need
 36 | def ideaProject = con.model(IdeaProject)
 37 |   .addProgressListener(listener)
 38 |   .get()
 39 | 
 40 | // Step 3: Get list of dependencies
 41 | def deps = ideaProject.children
 42 |   .dependencies
 43 |   .flatten()
 44 |   .findAll { it.scope.scope == "COMPILE" }
 45 |   .collect {
 46 |     [
 47 |       name   : it.gradleModuleVersion?.name,
 48 |       group  : it.gradleModuleVersion?.group,
 49 |       version: it.gradleModuleVersion?.version,
 50 |       file   : it.file?.path,
 51 |       source : it.source?.path,
 52 |       javadoc: it.javadoc?.path
 53 |     ]
 54 |   }
 55 | 
 56 | def classpathList = deps.file + [new File(projectDir, "build/classes/main").path]
 57 | ----
 58 | 
 59 | The above code is actually wrapped in a class. Connection and model instances are cached for performance reasons.
 60 | We connect to our gradle project. If the project ships with a gradle wrapper (which it should IMO), the gradle connector will use that version (download the distribution even if need be). Otherwise it will use the gradle version of the tooling-api. At the time of writing that's 1.12
 61 | The tooling api doesn't really expose as much information by default as you might wish. However it ships with an IdeaModel and an EclipseModel that provides what we need for the purposes of creating a class path. As an Idea user the IdeaModel seemed the right choice ! There is also added a progress listener, which is a callback from the api reporting progress. The progress listener returns each progress event as a string to Light Table so that we can display progress information
 62 | We basically navigate the model and extract information about dependencies and put it in a list of maps for ease of jsonifying (useful later !). The location of our projects custom compiled classes are added manually to the class path list (ideally should have been retrieved from the model as well...)
 63 | Adding the class path list to our groovy shell before code invocation
 64 | 
 65 | [source,groovy]
 66 | ----
 67 | private GroovyShell createShell(Map params) {
 68 | def transform = new ScriptTransform()
 69 | def conf = new CompilerConfiguration()
 70 |   conf.addCompilationCustomizers(new ASTTransformationCustomizer(transform))
 71 |   conf.addCompilationCustomizers(ic)
 72 | 
 73 |   if(params.classPathList) {
 74 |     conf.setClasspathList(params.classPathList)
 75 |   }
 76 | 
 77 |   new GroovyShell(conf)
 78 | }
 79 | ----
 80 | 
 81 | Its basically just a matter of adding the class path list to the CompilerConfiguration we initialise our GroovyShell with. Sweet !
 82 | Voila your groovy scripts can invoke any class in your project´s class path.
 83 | 
 84 | 
 85 | This addition basically resulted in version 0.0.4
 86 | 
 87 | == Reporting progress
 88 | 
 89 | === Groovy
 90 | 
 91 | [source,groovy]
 92 | ----
 93 | class ProgressReporter implements LTProgressReporter {
 94 |     final LTConnection ltCon
 95 | 
 96 |     ProgressReporter(LTConnection ltCon) { this.ltCon = ltCon }
 97 | 
 98 |     @Override
 99 |     void statusChanged(ProgressEvent event) {
100 |         if (event.description?.trim()) {
101 |             reportProgress(event.description)
102 |         }
103 |     }
104 | 
105 |     void reportProgress(String message) {
106 |         ltCon.sendData([null, "gradle.progress",[msg: message]])
107 |     }
108 | }
109 | ----
110 | 
111 | .Notes
112 | * statusChanges is called by gradle (LTProgressReporter extends the Gradle ProgressListener interface)
113 | * reportProgress sends the progress information to Light Table
114 | 
115 | === Light Table
116 | 
117 | [source,clojure]
118 | ----
119 | (behavior ::on-gradle-progress
120 |   :desc "Reporting of progress from gradle related tasks"
121 |   :triggers #{:gradle.progress}
122 |   :reaction (fn [this info]
123 |               (notifos/msg* (str "Gradle progress: " (:msg info)) {:timeout 5000})))
124 | ----
125 | 
126 | The progress behaviour just prints a message to the Light Table status bar.
127 | 
128 | 
129 | === Executing Gradle Tasks
130 | 
131 | There are two parts to this puzzle. One is to retrieve information about what tasks are actually available for the given project. The other is to actually invoke the task (tasks in the future).
132 | Listing tasks Groovy/Server
133 | 
134 | [source,groovy]
135 | ----
136 |  // Step 1: Retrieve generic Gradle model
137 | def gradleProject = con.model(GradleProject)
138 |   .addProgressListener(listener)
139 |   .get()
140 | 
141 | // Step 2: Get list of available tasks
142 | gradleProject.tasks.collect{
143 |   [
144 |     name: it.name,
145 |     displayName: it.displayName,
146 |     description: it.description,
147 |     path: it.path
148 |   ]
149 | }
150 | 
151 | // Step 3: Send task list to client (omitted, you get the general idea by now !)
152 | ----
153 | 
154 | 
155 | === Listing tasks in Light Table
156 | 
157 | The list of tasks is actually retrieved by the Light Table plugin once you select to connect to a gradle project. Furthermore the list is cached in an atom.
158 | 
159 | [source,clojure]
160 | ----
161 | (behavior ::on-gradle-projectinfo
162 |   :desc "Gradle project model information"
163 |   :triggers #{:gradle.projectinfo}
164 |   :reaction (fn [this info]
165 |               (object/merge! groovy {::gradle-project-info info})
166 |               (object/assoc-in! cmd/manager [:commands :gradle.task.select :options] (add-selector))))
167 | 
168 | ----
169 | When the groovy server has finished retrieving the tasks (and other project info) the above behaviour is triggered in Light Table:
170 | 
171 | We store the project info in our Groovy object (an atom)
172 | We also update the command for selecting tasks with the new list of tasks. See the section below for details.
173 | [source,clojure]
174 | ----
175 | (behavior ::set-selected
176 |   :triggers #{:select}
177 |   :reaction (fn [this v]
178 |               (scmd/exec-active! v)))
179 | 
180 | (defn selector [opts]
181 |   (doto (scmd/filter-list opts)
182 |     (object/add-behavior! ::set-selected)))
183 | 
184 | (defn get-tasks []
185 |   (->@groovy ::gradle-project-info :tasks))
186 | 
187 | (defn add-selector []
188 |   (selector {:items (get-tasks)
189 |              :key :name
190 |              :transform #(str "<p>" (:name %4) "</p>"
191 |                               "<p class='binding'>" (:description %4) "</p>")}))
192 | 
193 | (cmd/command {:command :gradle.task.select
194 |               :desc "Groovy: Select Gradle task"
195 |               :options (add-selector)
196 |               :exec (fn [item]
197 |                       (object/raise groovy :gradle.execute item))})
198 | 
199 | ----
200 | The above code adds a sub panel to the default sidebar command panel. When you select the command :gradle.task.select it will show a child panel listing the tasks from the get-tasks function.
201 | 
202 | image::lt_gr_tasks.png[]
203 | 
204 | [source,clojure]
205 | ----
206 | ;; Behavior to actually trigger execution of a selected task from the list above
207 | (behavior ::on-gradle-execute
208 |   :desc "Gradle execute task(s)"
209 |   :triggers #{:gradle.execute}
210 |   :reaction (fn [this task]
211 |               (clients/send
212 |                 (clients/by-name "Groovy")
213 |                 :gradle.execute
214 |                 {:tasks [(:name task)]})))
215 | ----
216 | 
217 | Once you have selected a task the above behaviour is triggered. We get hold of an editor agnostic groovy client and send an execute task message with a list of task (currently always just one). The data we send will be extended in the future to support multiple tasks and build arguments.
218 | 
219 | 
220 | Server side Task execution
221 | [source,groovy]
222 | ----
223 | // Generic execute task function
224 | def execute(Map params, Closure onComplete) {
225 |     def resultHandler = [
226 |         onComplete: {Object result ->
227 |             onComplete status: "OK"
228 |         },
229 |         onFailure: {GradleConnectionException failure ->
230 |             onComplete status: "ERROR", error: failure
231 |         }
232 |     ] as ResultHandler
233 | 
234 | 
235 |     con.newBuild()
236 |     .addProgressListener(listener)
237 |     .forTasks(params.tasks as String[])
238 |     .run(resultHandler)
239 | }
240 | ----
241 | Here we use the asynch features of the Gradle Tooling API. Executing a task may actually take a while so it certainly makes sense. Callers of the execute method will receive a callback (onComplete) once task execution is completed successfully (of failed).
242 | 
243 | [source,groovy]
244 | ----
245 | projectConnection.execute(params) {Map result ->
246 |     ltConnection.sendData([
247 |         null,
248 |         result.status == "ERROR" ? "gradle.execute.err" : "gradle.execute.success",
249 |         result
250 |     ])
251 | }
252 | ----
253 | 
254 | We invoke the execute method with a closure argument and return the results (success/failure) back to Light Table.
255 | 
256 | This brings us pretty much up to version 0.0.5
257 | 
258 | == Summary
259 | 
260 | Well we covered a lot of ground here. We can now call any class that's in your Gradle project's class path from a groovy editor in Light Table. We've also started on providing Gradle features that are language agnostic. Starting with support for listing and executing tasks in your gradle project.
261 | We've added decent progress reporting and performance seems to be pretty good too. Looks like we have something we can build further upon !
262 | 
263 | I have lots of ideas; Infinitesting,  single test with inline results, compile single file, grails integration ? etc etc. I also really want to show project dependencies in a graph. However before I can do any of those things I need to extend the tooling api with custom models ... and/or maybe I should see if I can contribute to the gradle project in extending the tooling-api with a richer generic project model.
264 | 
265 | We'll have to wait and see. Next week I'm off to gr8conf.eu in Copenhagen. Really looking forward to meeting up with all the great Groovy dudes/dudettes.  And who knows maybe the hackergarten evening will result in something new and exciting !

  1 | = A Groovy Light Table client - Step 5: Gradle dependencies in Light Table with dagre-D3
  2 | Magnus Rundberget
  3 | 2014-06-18
  4 | :jbake-type: post
  5 | :jbake-status: published
  6 | :jbake-tags: lighttable, groovy, clojurescript,gradle
  7 | :imagesdir: /blog/2014/
  8 | :id: gr_lt_part5
  9 | 
 10 | == Background
 11 | 
 12 | This is the fifth post in my series "A Groovy Light Table client". A blog series about steps I take when trying to build a Groovy plugin for Light Table.
 13 | 
 14 | === Tapping more into the Potential of Light Table
 15 | 
 16 | So far the Groovy Light Table plugin hasn't really showcased the real power of the Light Table Editor. What feature could showcase more of Light Table and at the same time prove useful in many scenarios ? For most projects I have worked on, the number of dependencies and their relationships have usually been non trivial. A couple of years back I wrote a post about showing gradle dependencies as a graphwiz png. Wouldn't it be cool if I could show my gradle dependencies  inline in Light Table ? It would be even cooler if the graph was interactive and provided more/different value than the default dependency reporting you got from Gradle itself
 17 | 
 18 | === dagre-D3
 19 | 
 20 | So what library should I choose for laying out my planned dependency diagram ? My first instinct was something related to D3. However laying out a dot-graph sensibly on my own didn't seem like a challenge I was quite up to. Luckily I found dagre-D3 and it looked to be just the thing I needed.  Of course I would have loved to have found something more clojurish and ideally something that supported an immediate mode ui (akin to Facebook React, but for graphing).  Maybe I didn't look long or well enough but I couldn't find anything obvious so I settled for https://github.com/cpettitt/dagre-d3[dagre-D3].
 21 | 
 22 | ===  Gradle dependencies
 23 | 
 24 | The second challenge I faced before even getting started was: How would I go about retrieving rich dependency information for my gradle projects using the tooling-api ? The information about dependencies default provided through the tooling api is fairly limited and wouldn't have produced a very informative graph at all. Luckily I found through dialog with the Gradle guys that it should be possible to achieve what I wanted through a custom gradle model.
 25 | 
 26 | == It's all about the data
 27 | 
 28 | When I initially started developing the custom gradle model for retrieving dependency information I designed a data structure that resembled the dependency modelling in Gradle. However after prototyping with dagre and later trying to display multi project dependency graphs I decided to change the design. I ended up with a data structure more similar to that of a graph with nodes and edges.
 29 | 
 30 | === Custom Gradle Model
 31 | 
 32 | To create a Custom Gradle Model you need to create a Gradle Plugin. My plugin got the very informative name "Generic Gradle Model" (naming is hard!).
 33 | 
 34 | [source,groovy]
 35 | ----
 36 | class GenericGradleModelPlugin implements Plugin {
 37 |     final ToolingModelBuilderRegistry registry;
 38 | 
 39 |     @Inject
 40 |     public GenericGradleModelPlugin(ToolingModelBuilderRegistry registry) {
 41 |         this.registry = registry;
 42 |     }
 43 | 
 44 |     @Override
 45 |     void apply(Project project) {
 46 |         registry.register(new CustomToolingModelBuilder())
 47 |     }
 48 | }
 49 | ----
 50 | 
 51 | The important bit above is registering my custom tooling builder to make it available to the tooling api !
 52 | 
 53 | [source,groovy]
 54 | ----
 55 | private static class CustomToolingModelBuilder implements ToolingModelBuilder {
 56 | 
 57 | // .. other private methods left out for brevity
 58 | 
 59 | Map confDiGraph(Configuration conf) {
 60 |   def nodeTree = conf.allDependencies
 61 |     .findAll {it instanceof ProjectDependency}
 62 |     .collect {getProjectDepInfo(it as ProjectDependency)} +
 63 |     conf.resolvedConfiguration
 64 |         .firstLevelModuleDependencies
 65 |         .collect { getDependencyInfo(it) }
 66 | 
 67 |     def nodes = nodeTree.collect {collectNodeEntry(it)}.flatten().unique {nodeId(it)}
 68 |     def edges = nodeTree.collect {
 69 |       collectEdge(conf.name, it)
 70 |     }.flatten().unique()
 71 | 
 72 |     [nodes: nodes, edges: edges]
 73 |   }
 74 | 
 75 |   Map projectDeps(Project project) {
 76 |     [
 77 |       name: project.name,
 78 |       group: project.group,
 79 |       version: project.version,
 80 |       configurations: project.configurations.collectEntries{Configuration conf ->
 81 |           [conf.name, confDiGraph(conf)]
 82 |       }
 83 |     ]
 84 |   }
 85 | 
 86 |   public boolean canBuild(String modelName) {
 87 |     modelName.equals(GenericModel.class.getName())
 88 |   }
 89 | 
 90 |   public Object buildAll(String modelName, Project project) {
 91 |     new DefaultGenericModel(
 92 |       rootDependencies: projectDeps(project),
 93 |       subprojectDependencies: project.subprojects.collect {projectDeps(it)}
 94 |   }
 95 | }
 96 | ----
 97 | 
 98 | The custom tooling model builder harvests information about all dependencies for all defined configurations in the project. If the project is a multi-project It will collect the same information for each subproject in addition to collect information about interdependencies between the sub projects.
 99 | 
100 | 
101 | === Applying the plugin to gradle projects we connect to
102 | 
103 | Before we can retrieve our custom gradle model, we need to apply the plugin to the project in question. I could ask the users to do it themselves, but that wouldn't be particularly user friendly.
104 | Luckily Gradle provides init scripts that you can apply to projects and the tooling api supports doing so. Init scripts allows you to do... well ... init stuff for your projects. Applying a plugin from the outside falls into that category.
105 | 
106 | [source,groovy]
107 | ----
108 | initscript {
109 |   repositories {
110 |     maven { url 'http://dl.bintray.com/rundis/maven' }
111 |   }
112 |   dependencies { classpath "no.rundis.gradle:generic-gradle-model:0.0.2" }
113 | }
114 | 
115 | allprojects {
116 |   apply plugin: org.gradle.tooling.model.generic.GenericGradleModelPlugin
117 | }
118 | ----
119 | 
120 | 
121 | === Retrieving the model
122 | [source,groovy]
123 | ----
124 | def genericModel = con.action(new GetGenericModelAction())
125 |                             .withArguments("--init-script", new File("lib/lt-project-init.gradle").absolutePath)
126 |                             .addProgressListener(listener)
127 |                             .run()
128 | 
129 | private static class GetGenericModelAction implements Serializable, BuildAction {
130 |   @Override
131 |   GenericModel execute(BuildController controller) {
132 |     controller.getModel(GenericModel)
133 |   }
134 | }
135 | ----
136 | 
137 | 
138 | To retrieve the model we use a custom build action and applies the plugin implementing the custom model using the --init-script command line argument for gradle.
139 | 
140 | Voila we have the data we need and we return the dependency info (async) after you have connected to a gradle project.
141 | 
142 | 
143 | == Show me a graph
144 | 
145 | The dependency graph and associated logic was separated out to a separate namespace (graph.cljs).
146 | We'll quickly run through some of the highlights of the LightTable clojurescript parts for displaying the dependency graph.
147 | 
148 | 
149 | === Graph object
150 | [source,clojure]
151 | ----
152 | (defui dependency-graph-ui [this]
153 |   [:div.graph
154 |    [:div.dependency-graph
155 |     [:svg:svg {:width "650" :height "680"}
156 |      [:svg:g {:transform "translate(20,20)"}]]]])
157 | 
158 | (object/object* ::dependency-graph
159 |                 :tags [:graph.dependency]
160 |                 :name "Dependency graph"
161 |                 :init (fn [this]
162 |                         (load/js (files/join plugin-dir "js/d3.v3.min.js") :sync)
163 |                         (load/js (files/join plugin-dir "js/dagre-d3.js") :sync)
164 |                         (let [content (dependency-graph-ui this)]
165 |                           content)))
166 | ----
167 | 
168 | The first step was to create and object that represents the view (and is able to hold the dependency data). The init method is responsible for loading the required graphing libs and then it creates the initial placeholder markup for the graph.
169 | 
170 | 
171 | === Some behaviours
172 | 
173 | [source,clojure]
174 | ----
175 | (behavior ::on-dependencies-loaded
176 |           :desc "Gradle dependencies loaded for selected project"
177 |           :triggers #{:graph.set.dependencies}

180 |                                            :subDeps subDeps})))

189 | ----
190 | 
191 | The first behavior is triggered when the groovy backend has finished retrieving the project info, and more specifically the dependencies. If the project is a single project only the rootDeps will contain data.
192 | 
193 | The second behavior is triggered (by a command) when the user wishes to view the dependency graph for a connected gradle project.
194 | 
195 | === Render Multiproject graph Hightlighs
196 | 
197 | For multi projects the plugin renders an overview graph where you can see the interdependencies between you sub projects.
198 | 
199 | [source,clojure]
200 | ----
201 | (defn create-multiproject-graph [this]
202 |   (let [g (new dagreD3/Digraph)]
203 |     (doseq [x (:nodes (multi-proj-deps this))]
204 |       (.addNode g (dep-id x) #js {:label (str "<div class='graph-label clickable' data-proj-name='"
205 |                                               (:name x) "' title='"
206 |                                               (dep-id x) "'>"
207 |                                               (:name x) "<br/>"
208 |                                               (:version x)
209 |                                               "</div>")}))
210 |     (doseq [x (:edges (multi-proj-deps this))]
211 |       (.addEdge g nil (:a x) (:b x) #js {:label ""}))
212 |     g))
213 | 
214 | (defn render-multi-deps [this]
215 |   (let [renderer (new dagreD3/Renderer)
216 |         g (dom/$ :g (:content @this))
217 |         svg (dom/$ :svg (:content @this))
218 |         layout (.run renderer (create-multiproject-graph this) (d3-sel g))
219 |         dim (dimensions this)]
220 |     (unbind-select-project this)
221 |     (bind-select-project this)
222 |     (.attr (d3-sel svg) "width" (+ (:w dim) 20))
223 |     (.attr (d3-sel svg) "height" (+ (:h dim) 20))))
224 | ----
225 | 
226 | The first function shows how we use dagre-D3 to create a logical dot graph representation. We basically add nodes and edges (dep->dep). Most of the code is related to what's rendered inside each node.
227 | 
228 | The second function shows how we actually layout and display the graph.  In addition we bind click handlers to our custom divs inside the nodes. The click handlers allows for drill down into a detailed graph about each dependency configuration.
229 |

241 | 
242 | == Conclusion
243 | 
244 | I think we achieved some pretty cool things. Maybe not a feature that you need everyday, but its certainly useful to get an overview of your project dependencies. For troubleshooting transitive dependency issues and resolution conflicts etc you might need more details though.
245 | 
246 | We have certainly showcased that you can do some really cool things with Light Table that you probably wouldn't typically do (easily) with a lot of other editors and IDE's. We have also dug deeper into the gradle tooling api. The gradle tooling api when maturing even more will provide some really cool new options for  JVM IDE integrations. A smart move by gradleware that opens up for integrations from a range of editors, IDE's and specialised tools and applications.
247 | 
248 | The end result of the dependency graph integration became the largest chunk of the 0.0.6 release.

  1 | = A Groovy Light Table client - Step 1: Connecting the client

 12 | == Building a plugin in Light Table
 13 | This is the first post in (hopefully) a series of blog posts about the various steps I go through when trying to create a plugin for Light Table. I have decided to try to create a Groovy plugin. I chose Groovy to ensure there was at least one technology fairly familiar to me. I have just started using Light Table, I have no previous experience with ClojureScript and I have just recently started writing some Clojure beyond the basic tutorials.
 14 | 
 15 | The short term goal is for the plugin to provide inline results and maybe an instarepl of some sort for groovy scripts.
 16 | 
 17 | https://github.com/rundis/LightTable-Groovy[LightTable-Groovy] is the name of my plugin project and you can find the latest source there. It might be a couple of steps ahead of the blog posts though !
 18 | 
 19 | == Documentation
 20 | Light Table was made http://www.chris-granger.com/2014/01/07/light-table-is-open-source/[open source] in january and documentation for plugin developers is a little sparse.
 21 | 
 22 | .So to have something to go by I decided to use some of the other language plugins as inspiration:
 23 | * https://github.com/LightTable/Python[Python plugin] (comes bundled/under the light table umbrella)
 24 | * https://github.com/existentialmutt/lt-ruby[Ruby Instarepl]
 25 | * https://github.com/jetaggart/light-haskell[Haskell plugin]
 26 | 
 27 | I haven't worked with any of the above mentioned languages, but they did provide enough inspiration to deduce how a Light Table client might interact.
 28 | 
 29 | BTW. A quick starter just to get you up an running with a hello world plugin could be this screen cast by Mike Haney.
 30 | 
 31 | 
 32 | == Connecting a client - Process overview
 33 | Before we dwelve into the code It's a good idea to have a high level understanding of what we are trying to achieve !
 34 | 
 35 | .A couple of use cases that needs to be supported:
 36 | * Evaluate current selection or current line of groovy code and present results (preferably inline)
 37 | * Evaluate contents of current editor and present results
 38 | * Provide as much info about the results of each statement as possible
 39 | * (Maybe need to evaluate line/statement by statement)
 40 | 
 41 | For a future instarepl, any change in the editor will trigger an evaluation
 42 | It becomes evident that our plugin needs to provide some kind of process that reacts to events from light table.
 43 | 
 44 | .A default pattern for achieving this has been devised for Light Table and roughly equates to the following steps:
 45 | . A connect event is triggered from Light Table (you need to set up your plugin to trigger that event…). Typically the connect event can be invoked manually from the connect bar in light table, or it can be triggered implicetly when evaluating code.
 46 | . You fire of a process - Using inbuilt support from Light Table you start a process either a shell script or whatever really. I created a shell script that sets some environment stuff and then basically kicks off a groovy script. Light table provides a tcp/ip port and a unique client id which you need to forward to the process.
 47 | . Create a tcp client: In your process you create a tcp client using the given port
 48 | . Send ack message: Send a json message with client id and an event name (behavior) to Light Table (through the tcp connection!)
 49 | . Confirm handshake for process: In your process (i.e. not the tcp connection!) write "Connected" to standard out. ("Connected" is just what the other plugins use, you could use  anything you like as long as it matches the connect behaviors(handlers) you provide inside light table.)
 50 | . Listen for events: Now you are connected and given you have set up your behaviors in Light Table correctly, your new connection should be reported as connected and shown in the Light Table connect bar. Now you listen for events on your tcp client and provides appropriate responses back to Light Table accordingly. (Handling this is the subject of a future blog post)

121 | 
122 | ----
123 | 
124 | .Notes:
125 | * scl/add-connector: This statement adds a connect dialog to our groovy plugin. You select a root directory and upon selection the ::connect behavior is triggered
126 | * ::connect basically responds with invoking a method for connecting. This does some sanity checks and if all goes well ends up invoking  run-groovy.
127 | * run-groovy : Fires up our groovy (server) process
128 | * def groovy   is basically the "mother" object of our plugin. It helps us scope behaviors and commands
129 |

221 | ----
222 | 
223 | 
224 | The above behaviors basically handles signaling success, error or connection exits for our groovy client. As you can see in ::on-out this is where we check standard out from the process for the string "Connected", to signal success.
225 | 
226 | 
227 | === Wiring up behaviors (behaviors.groovy)
228 | [source,clojure]
229 | ----
230 | {:+ {:app [(:lt.objs.plugins/load-js ["codemirror/groovy.js", "groovy_compiled.js"])]
231 |      :clients []
232 |      :editor.groovy []
233 |      :files [(:lt.objs.files/file-types
234 |               [{:name "Groovy" :exts [:groovy] :mime "text/x-groovy" :tags [:editor.groovy]}])]
235 |      :groovy.lang [:lt.plugins.groovy/connect]}}
236 | ----
237 | 
238 | The important part in terms on the connection is the wiring of the connect behavior to ":groovy.lang". This is needed for groovy to appear as a connection item in the light table connect bar.
239 | 
240 | "codemirror/groovy.js" deserves a special mention. This is what provides syntax highlighting for our groovy files (defined in the :files vector). The syntax highlighting is provided by the groovy mode module from CodeMirror.
241 | 
242 | == Wrapping up
243 | So what have we achieved. Well we now have a connection to Light Table from an external process that can listen and respond to events from Light Table. For the purposes of this blog post series, its a Groovy client that hopefully pretty soon will be able to evaluate groovy scripts and respond with evaluation results. We didn't pay much attention to it, but we also got syntax highlighting of our Groovy files complements of CodeMirror.
244 | 
245 | It took a while to grok how the connection part worked. Once I did understand roughly what was needed I was a bit annoyed with myself for messing about so much. I'm hoping this post might help others to avoid some of the mistakes I stumbled into.

 12 | 
 13 | This is the second post in my series "A Groovy Light Table client". A blog series about steps I take when trying to build a Groovy plugin for Light Table.
 14 | 
 15 | In this post I will take you through some of the steps I went through to get Light Table to evaluate groovy (script) code and show results inline in the editor.
 16 | 
 17 | image::lt_groovy_eval.png[]
 18 | 
 19 | == How did we get here ?
 20 | 
 21 | 
 22 | === Evaluate contents of editor (cmd/ctrl + shift + enter)
 23 | [source,clojure]
 24 | ----
 25 | (behavior ::on-eval
 26 |           :desc "Groovy: Eval current editor"

 28 |           :reaction (fn [editor]
 29 |                       (object/raise groovy :eval! {:origin editor
 30 |                                                    :info (assoc (@editor :info)

 33 | ----
 34 | This behavior triggers on ":eval", which is triggered to any editor (on cmd/ctrl + shift + enter in default key mapping). We just get hold of the text from the editor and gather some meta info  and trigger a ":eval!" behavior on the groovy "mother" object defined in the previous blog post.

 69 | ----
 70 | This behavior is what actually sends off a eval request to the groovy client. Quite a lot happens under the hood (by help of inbuilt LightTable behaviors):
 71 | 
 72 | It tries to find a client (connection) for the editor
 73 | If no connection exists it will try to create a new one. On create it will invoke the try-connect function that we defined for the gui connect/connect bar behavior in the previous blog post
 74 | Once connected it will jsonify our parameters and send them off to our groovy client
 75 | 
 76 | .The JSON might look something like:
 77 | [source,javascript]

 91 | .Notes
 92 | * The first param is the client id for the editor that triggered the behavior. This client Id doesn't represent the same as a connection id (ref previous blog post). Many editors may share the same connection !
 93 | * The second param is the command (our groovy client will of course support many different commands, this is one of them)
 94 | * The third and last parameter is our info. The code is the essential bit, but some of the meta information, like line info comes in handy when handling the response later on

144 | ----
145 | 
146 | The first and most significant line is where we evaluate the groovy code received. This post would be too long if we went into all the details of what it does, but here's a high-level summary:
147 | 
148 | We basically create a GroovyShell and compile our code to a script. Normally that would just compile a Script class. However we  wish to collect a lot more information than you typically would get from default groovy script execution. So we do an AST transformation on the script class and add a custom abstract script class as a base class for the compiled script class.  This allows us to inject behavior and wrap statement execution (all compiled into the script for optimal performance).  That way we are able to collect information about values for most types of statements. We collect line number and value (each line could end up having many values :-) )
149 | We run the script (capturing system.out and system.err).
150 | 
151 | .The function returns:
152 | * Anything written to standard out (println etc)
153 | * Errors if any and line number for error where possible
154 | * A list for of maps with line number and value(s)
155 | 
156 | Most of the AST stuff is not something I've written. It's been contributed by Jim White after I posted a question on the groovy-user mailing list. I asked for advice on which way to proceed and the response from the groovy community was awesome. Jim in particular was more than eager to contribute to the plugin. OpenSource rocks ! So when I say we, I sometimes mean we literally.
157 | 
158 | Anyways, based on the results of the script execution we notify Light Table to trigger either a ":groovy.res" behavior or a "groovy.err" behavior.
159 | 
160 | The json response for sendData for a successful execution might look something like:
161 | 
162 | [source,javascript]
163 | ----
164 | [89,
165 |  "groovy.res",
166 |  {"meta":{"start":22,"end":23},"out":"hello\nmama\n","result":[{"line":1,"values":["null"]},{"line":2,"values":["null"]}]}]

194 | ----
195 | 
196 | These are the behavior definitions that handles either successful or evaluation of scripts with errors. Basically we:
197 | Print to the Light Table Console anything that was captured to system.out/system.err by our groovy evaluation
198 | Show inline results for each line, multiple results for a line are space separated. For showing inline results we are using a predefined Light Table behavior (:editor.result)
199 | If the behavior is to handle an error, we show evaluation results up until the script exception. In addition we display details (stack trace) for the exception at the line in the script it occurred

218 | ----
219 | The eval and results/err behaviors are defined for the editor tag. So they are only applicable for editors marked as groovy editors. Any editor open with a file name ending in .groovy will automatically be attached to a editor.groovy tag. (You can also set it manually cmd+space -> "Editor: Set current editor syntax").
220 | The ":eval!" behavior is defined for the :groovy.lang tag. Its tied to our groovy mother object just like the connect behavior. These behaviors are totally groovy client specific, whilst the other behaviors are less so (although not exactly generic as they are now…)
221 | 
222 | == Wrap up
223 | 
224 | A little bit of plumbing was needed to get this set up. But the hard parts was really coming up with the groovy AST transformation stuff. I guess by now you might have started getting an inkling that Light Table is fairly composable ? It really is super flexible. You don't like the behavior for handling inline results for the groovy plugin ? You could easily write your own and wire it up in your user.behaviors file in Light Table. It's wicked cool, actually it really is your editor !
225 | 
226 | Yesterday I released version 0.0.2 of the Groovy LightTable plugin. Its available through the Light Table plugin manager, or if you wish to play with the code or maybe feel like contributing feel free to fork the repo at : https://github.com/rundis/LightTable-Groovy. Pull requests are welcome.
227 | 
228 | So where to next ? I'd really like to try and create an InstaRepl editor for the plugin. A groovy script editor that evaluates code as you type. There's gotta be one or two challenges related to that. A quick win might be to provide groovy api documentation from inside Light Table. I'll let you know what happens in the next post.
229 | 
230 | [NOTE]
231 | ====
232 | Disclaimer: I might have misunderstood some nuances of Light Table, but hopefully I'm roughly on track. If you see anything glaringly wrong, do let me know.
