ANY USE, REPRODUCTION OR DISTRIBUTION OF THE PROGRAM 3 | CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT. 4 | 5 | 1. DEFINITIONS 6 | 7 | "Contribution" means: 8 | 9 | a) in the case of the initial Contributor, the initial code and 10 | documentation distributed under this Agreement, and 11 | 12 | b) in the case of each subsequent Contributor: 13 | 14 | i) changes to the Program, and 15 | 16 | ii) additions to the Program; 17 | 18 | where such changes and/or additions to the Program originate from and are 19 | distributed by that particular Contributor. A Contribution 'originates' from 20 | a Contributor if it was added to the Program by such Contributor itself or 21 | anyone acting on such Contributor's behalf. Contributions do not include 22 | additions to the Program which: (i) are separate modules of software 23 | distributed in conjunction with the Program under their own license 24 | agreement, and (ii) are not derivative works of the Program. 25 | 26 | "Contributor" means any person or entity that distributes the Program. 27 | 28 | "Licensed Patents" mean patent claims licensable by a Contributor which are 29 | necessarily infringed by the use or sale of its Contribution alone or when 30 | combined with the Program. 31 | 32 | "Program" means the Contributions distributed in accordance with this 33 | Agreement. 34 | 35 | "Recipient" means anyone who receives the Program under this Agreement, 36 | including all Contributors. 37 | 38 | 2. GRANT OF RIGHTS 39 | 40 | a) Subject to the terms of this Agreement, each Contributor hereby grants 41 | Recipient a non-exclusive, worldwide, royalty-free copyright license to 42 | reproduce, prepare derivative works of, publicly display, publicly perform, 43 | distribute and sublicense the Contribution of such Contributor, if any, and 44 | such derivative works, in source code and object code form. 45 | 46 | b) Subject to the terms of this Agreement, each Contributor hereby grants 47 | Recipient a non-exclusive, worldwide, royalty-free patent license under 48 | Licensed Patents to make, use, sell, offer to sell, import and otherwise 49 | transfer the Contribution of such Contributor, if any, in source code and 50 | object code form. This patent license shall apply to the combination of the 51 | Contribution and the Program if, at the time the Contribution is added by the 52 | Contributor, such addition of the Contribution causes such combination to be 53 | covered by the Licensed Patents. The patent license shall not apply to any 54 | other combinations which include the Contribution. No hardware per se is 55 | licensed hereunder. 56 | 57 | c) Recipient understands that although each Contributor grants the licenses 58 | to its Contributions set forth herein, no assurances are provided by any 59 | Contributor that the Program does not infringe the patent or other 60 | intellectual property rights of any other entity. Each Contributor disclaims 61 | any liability to Recipient for claims brought by any other entity based on 62 | infringement of intellectual property rights or otherwise. As a condition to 63 | exercising the rights and licenses granted hereunder, each Recipient hereby 64 | assumes sole responsibility to secure any other intellectual property rights 65 | needed, if any. For example, if a third party patent license is required to 66 | allow Recipient to distribute the Program, it is Recipient's responsibility 67 | to acquire that license before distributing the Program. 68 | 69 | d) Each Contributor represents that to its knowledge it has sufficient 70 | copyright rights in its Contribution, if any, to grant the copyright license 71 | set forth in this Agreement. 72 | 73 | 3. REQUIREMENTS 74 | 75 | A Contributor may choose to distribute the Program in object code form under 76 | its own license agreement, provided that: 77 | 78 | a) it complies with the terms and conditions of this Agreement; and 79 | 80 | b) its license agreement: 81 | 82 | i) effectively disclaims on behalf of all Contributors all warranties and 83 | conditions, express and implied, including warranties or conditions of title 84 | and non-infringement, and implied warranties or conditions of merchantability 85 | and fitness for a particular purpose; 86 | 87 | ii) effectively excludes on behalf of all Contributors all liability for 88 | damages, including direct, indirect, special, incidental and consequential 89 | damages, such as lost profits; 90 | 91 | iii) states that any provisions which differ from this Agreement are offered 92 | by that Contributor alone and not by any other party; and 93 | 94 | iv) states that source code for the Program is available from such 95 | Contributor, and informs licensees how to obtain it in a reasonable manner on 96 | or through a medium customarily used for software exchange. 97 | 98 | When the Program is made available in source code form: 99 | 100 | a) it must be made available under this Agreement; and 101 | 102 | b) a copy of this Agreement must be included with each copy of the Program. 103 | 104 | Contributors may not remove or alter any copyright notices contained within 105 | the Program. 106 | 107 | Each Contributor must identify itself as the originator of its Contribution, 108 | if any, in a manner that reasonably allows subsequent Recipients to identify 109 | the originator of the Contribution. 110 | 111 | 4. COMMERCIAL DISTRIBUTION 112 | 113 | Commercial distributors of software may accept certain responsibilities with 114 | respect to end users, business partners and the like. While this license is 115 | intended to facilitate the commercial use of the Program, the Contributor who 116 | includes the Program in a commercial product offering should do so in a 117 | manner which does not create potential liability for other Contributors. 118 | Therefore, if a Contributor includes the Program in a commercial product 119 | offering, such Contributor ("Commercial Contributor") hereby agrees to defend 120 | and indemnify every other Contributor ("Indemnified Contributor") against any 121 | losses, damages and costs (collectively "Losses") arising from claims, 122 | lawsuits and other legal actions brought by a third party against the 123 | Indemnified Contributor to the extent caused by the acts or omissions of such 124 | Commercial Contributor in connection with its distribution of the Program in 125 | a commercial product offering. The obligations in this section do not apply 126 | to any claims or Losses relating to any actual or alleged intellectual 127 | property infringement. In order to qualify, an Indemnified Contributor must: 128 | a) promptly notify the Commercial Contributor in writing of such claim, and 129 | b) allow the Commercial Contributor tocontrol, and cooperate with the 130 | Commercial Contributor in, the defense and any related settlement 131 | negotiations. The Indemnified Contributor may participate in any such claim 132 | at its own expense. 133 | 134 | For example, a Contributor might include the Program in a commercial product 135 | offering, Product X. That Contributor is then a Commercial Contributor. If 136 | that Commercial Contributor then makes performance claims, or offers 137 | warranties related to Product X, those performance claims and warranties are 138 | such Commercial Contributor's responsibility alone. Under this section, the 139 | Commercial Contributor would have to defend claims against the other 140 | Contributors related to those performance claims and warranties, and if a 141 | court requires any other Contributor to pay any damages as a result, the 142 | Commercial Contributor must pay those damages. 143 | 144 | 5. NO WARRANTY 145 | 146 | EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON 147 | AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER 148 | EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR 149 | CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A 150 | PARTICULAR PURPOSE. Each Recipient is solely responsible for determining the 151 | appropriateness of using and distributing the Program and assumes all risks 152 | associated with its exercise of rights under this Agreement , including but 153 | not limited to the risks and costs of program errors, compliance with 154 | applicable laws, damage to or loss of data, programs or equipment, and 155 | unavailability or interruption of operations. 156 | 157 | 6. DISCLAIMER OF LIABILITY 158 | 159 | EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY 160 | CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, 161 | SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION 162 | LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN 163 | CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) 164 | ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE 165 | EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY 166 | OF SUCH DAMAGES. 167 | 168 | 7. GENERAL 169 | 170 | If any provision of this Agreement is invalid or unenforceable under 171 | applicable law, it shall not affect the validity or enforceability of the 172 | remainder of the terms of this Agreement, and without further action by the 173 | parties hereto, such provision shall be reformed to the minimum extent 174 | necessary to make such provision valid and enforceable. 175 | 176 | If Recipient institutes patent litigation against any entity (including a 177 | cross-claim or counterclaim in a lawsuit) alleging that the Program itself 178 | (excluding combinations of the Program with other software or hardware) 179 | infringes such Recipient's patent(s), then such Recipient's rights granted 180 | under Section 2(b) shall terminate as of the date such litigation is filed. 181 | 182 | All Recipient's rights under this Agreement shall terminate if it fails to 183 | comply with any of the material terms or conditions of this Agreement and 184 | does not cure such failure in a reasonable period of time after becoming 185 | aware of such noncompliance. If all Recipient's rights under this Agreement 186 | terminate, Recipient agrees to cease use and distribution of the Program as 187 | soon as reasonably practicable. However, Recipient's obligations under this 188 | Agreement and any licenses granted by Recipient relating to the Program shall 189 | continue and survive. 190 | 191 | Everyone is permitted to copy and distribute copies of this Agreement, but in 192 | order to avoid inconsistency the Agreement is copyrighted and may only be 193 | modified in the following manner. The Agreement Steward reserves the right to 194 | publish new versions (including revisions) of this Agreement from time to 195 | time. No one other than the Agreement Steward has the right to modify this 196 | Agreement. The Eclipse Foundation is the initial Agreement Steward. The 197 | Eclipse Foundation may assign the responsibility to serve as the Agreement 198 | Steward to a suitable separate entity. Each new version of the Agreement will 199 | be given a distinguishing version number. The Program (including 200 | Contributions) may always be distributed subject to the version of the 201 | Agreement under which it was received. In addition, after a new version of 202 | the Agreement is published, Contributor may elect to distribute the Program 203 | (including its Contributions) under the new version. Except as expressly 204 | stated in Sections 2(a) and 2(b) above, Recipient receives no rights or 205 | licenses to the intellectual property of any Contributor under this 206 | Agreement, whether expressly, by implication, estoppel or otherwise. All 207 | rights in the Program not expressly granted under this Agreement are 208 | reserved. 209 | 210 | This Agreement is governed by the laws of the State of New York and the 211 | intellectual property laws of the United States of America. No party to this 212 | Agreement will bring a legal action under this Agreement more than one year 213 | after the cause of action arose. Each party waives its rights to a jury trial 214 | in any resulting litigation. 215 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # Proto REPL Demo 2 | 3 | This is a sample Clojure project meant to demonstrate the [Proto REPL](https://github.com/jasongilman/proto-repl) package for the [Atom](https://atom.io) editor. 4 | 5 | 6 | ## Setup 7 | 8 | 1.

It assumes you've followed the setup steps in the README first. Follow the steps in this file to see a demonstration of the different capabilities of Proto REPL. 4 | 5 | ## A Note About Keyboard Shortcuts 6 | 7 | Keyboard shortcuts below refer to using `ctrl-alt-,` then a letter. That means press the `ctrl` key, `alt` key, and the comma key at the same time, release them, and then press the subsequent letter. Some keyboard shortcuts also include the shift key. 8 | 9 | ## Demo: Start the REPL 10 | 11 | Start the REPL using one of the following methods. 12 | 13 | * Use the keyboard shortcut - `ctrl-alt-, L` 14 | * Select the menu item "Packages" -> "proto-repl" -> "Start REPL" 15 | * Bring up the Command Palette (ctrl-alt-, p) and select "Proto REPL: Toggle" 16 | 17 | ### How Does it Work? 18 | 19 | When the REPL starts in Proto REPL it runs the Clojure build tool, Leiningen as a child process. Leiningen starts a Clojure REPL using the current project's classpath. Proto REPL sends code to the REPL which is evaluated. Any standard out from the REPL including the evaluation response is returned and displayed in the REPL. 20 | 21 | ## Demo: Start the REPL with Boot 22 | 23 | [Boot](https://github.com/boot-clj/boot) is supported for running the REPL as well. If both a `project.clj` file (Leiningen style project file) and a `build.boot` file (Boot style build file) then the setting called "Prefer Lein" will determine which is used. proto-repl-demo has both kinds of build files. 24 | 25 | Trying out Boot: 26 | 27 | Make sure you have boot is installed, uncheck "Prefer Lein" in the Proto REPL settings, then start the REPL. Proto REPL settings can be accessed in Atom by opening "Preferences" from the main menu, then selecting the "Packages" tab. Proto REPL will be one of the packages listed. 28 | 29 | ## Demo: Send a Block of Clojure Code to the REPL 30 | 31 | Put your cursor somewhere within the statement below and press `ctrl-alt-, b`. 32 | 33 | ```clojure 34 | (+ 1 2 3) 35 | ``` 36 | 37 | Try placing your cursor in different sections in this more sophisticated example. Depending on which block you execute you may get a compiler exception because certain variable names will not be bound. See [the Proto REPL README](https://github.com/jasongilman/proto-repl#sending-a-block) for a description of a how it finds which block to execute. 38 | 39 | Note that if you place your cursor outside of block but within the Markdown code block the entire block will be executed. 40 | 41 | ```clojure 42 | (let [numbers (range 1 11)] 43 | (map #(* 2 %) numbers)) 44 | ``` 45 | 46 | ### Executing the Outermost Block 47 | 48 | Proto REPL allows execution of the outermost block no matter what the location of your cursor is. Put your cursor anywhere within the block above and press `ctrl-alt-, shift-b`. 49 | 50 | ## Demo: Send Selected Text to the REPL 51 | 52 | Select the three `println` statements below (including parentheses) and press `ctrl-alt-, s`. Note that all the commands are executed but only the result from the last one is returned (`nil`). 53 | 54 | ```clojure 55 | (println "hello 1") 56 | (println "hello 2") 57 | (println "hello 3") 58 | ``` 59 | 60 | ## Demo: Interrupting a Long Running Command (Clojure Only) 61 | 62 | Proto REPL allows you to interrupt a long running command using `ctrl-shift-c`. Try running the code below which will run forever and then interrupt it. 63 | 64 | ```clojure 65 | (while true 66 | (Thread/sleep 500) 67 | (println "I'm still running")) 68 | ``` 69 | 70 | ## Demo: Refresh all Code in the Project 71 | 72 | All of the code in the project can be loaded and refreshed from the file system by pressing the tool bar button or using the keyboard shortcut `ctrl-alt-, R`. It works by executing the `reset` function in the `user` namespace. This is defined in this project in `dev/user.clj`. The `reset` function uses [clojure.tools.namespace](https://github.com/clojure/tools.namespace) to load all the code in the project. 73 | 74 | 1. Reload all code using `ctrl-alt-, r`. 75 | 2. Open dev/user.clj 76 | 3. Uncomment the line in the `start` function. 77 | 4. Reload all code using `ctrl-alt-, r`. You should see "Starting" is printed in the REPL indicating your code change was loaded. 78 | 79 | ## Demo: Run All Tests 80 | 81 | Run all the tests in the project by pressing the tool bar button or hitting the keyboard shortcut `ctrl-alt-, a`. When you do you should see that one of the tests fails. 82 | 83 | ## Demo: Run a Single Test File 84 | 85 | Open `test/proto_repl_demo/demo_test.clj`. Run the tests in that namespace by pressing `ctrl-alt-, x`. That runs all of the tests in that namespace. 86 | 87 | ## Demo: Run a Single Test 88 | 89 | Put your cursor within the name of a test in the `test/proto_repl_demo/demo_test.clj` file. Press `ctrl-alt-, t` to run the test under the cursor. 90 | 91 | ## Demo: Load a single file. 92 | 93 | Sometimes you don't want to reload all the code in a project and you don't want to evaluate each block separately. You can load a single file using the `ctrl-alt-, f` keybinding. 94 | 95 | ## Demo: View Documentation or Code of a Function. 96 | 97 | Put your cursor within the text `vector` in this file and press `ctrl-alt-, d`. This will print the documentation for that Clojure function. Leave your cursor within the same text and try pressing `ctrl-alt-, c` to display the source code of that function. 98 | 99 | You can show documentation or code for a function in a namespace other that clojure.core. Put your cursor within the name `clojure.string/join` and press `ctrl-alt-, d`. 100 | 101 | ## Demo: View List of Functions in a Namespace. 102 | 103 | Put your cursor within the text of the namespace name `clojure.string` and press `ctrl-alt-, n` to list the vars defined in that namespace. Try pressing `ctrl-alt-shift-, n` to list the vars with documentation. 104 | 105 | ## Demo: Open Namespace or Var Definition 106 | 107 | The open command is triggered by placing your cursor within a var reference and pressing `ctrl-alt-, o`. Try placing your cursor in each of the following and pressing `ctrl-alt-, o` 108 | 109 | * A namespace in this project: `proto-repl-demo.demo` 110 | * A var in this project: `proto-repl-demo.demo/subtract-numbers` 111 | * A var in Clojure: `clojure.string/join` 112 | * A var in a library: `clojure.tools.namespace.repl/refresh` 113 | 114 | Pretty much anytime you see a var or namespace in Clojure code you can open it. The open command finds the location of a var either on the local file system or in a referenced library. If the var is located in a library the code from the jar is extracted to `~/.lein/tmp-atom-jars/` and opened there. If the jar was already extracted it uses that first. 115 | 116 | ## Demo: Autoeval File 117 | 118 | Open auteval.clj for an example of Autoeval. 119 | -------------------------------------------------------------------------------- /deps.edn: -------------------------------------------------------------------------------- 1 | {:deps {org.clojure/clojure {:mvn/version "1.9.0"} 2 | proto-repl {:mvn/version "0.3.1"} 3 | proto-repl-charts {:mvn/version "0.3.1"} 4 | org.clojure/tools.namespace {:mvn/version "0.2.11"} 5 | org.clojure/tools.nrepl {:mvn/version "0.2.12"}}} 6 | -------------------------------------------------------------------------------- /dev/user.clj: -------------------------------------------------------------------------------- 1 | (ns user 2 | (:require [clojure.tools.namespace.repl :as tnr] 3 | [clojure.repl] 4 | [prc] 5 | [proto-repl.saved-values])) 6 | 7 | (defn start 8 | [] 9 | ; (println "I'm starting now") 10 | (println "Start completed")) 11 | 12 | (defn reset [] 13 | (tnr/refresh :after 'user/start)) 14 | 15 | (println "proto-repl-demo dev/user.clj loaded.") 16 | -------------------------------------------------------------------------------- /project.clj: -------------------------------------------------------------------------------- 1 | (defproject proto-repl-demo "0.1.0-SNAPSHOT" 2 | :description "A sample Clojure project for demoing capabilities of the Proto REPL package for the Atom editor." 3 | :url "https://github.com/jasongilman/proto-repl-demo" 4 | :license {:name "Eclipse Public License" 5 | :url "http://www.eclipse.org/legal/epl-v10.html"} 6 | :dependencies [[org.clojure/clojure "1.8.0"] 7 | [proto-repl "0.3.1"] 8 | [proto-repl-charts "0.3.1"]] 9 | 10 | :profiles 11 | {:dev {:source-paths ["dev" "src" "test"] 12 | :dependencies [[org.clojure/tools.namespace "0.2.11"]]}}) 13 | -------------------------------------------------------------------------------- /src/proto_repl_demo/conditional.cljc: -------------------------------------------------------------------------------- 1 | (ns proto-repl-demo.conditional 2 | "This namespace allows testing reader conditionals of proto repl.
