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 Washington 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 | # pushy 2 | [![Build Status](https://travis-ci.org/kibu-australia/pushy.svg?branch=master)](https://travis-ci.org/kibu-australia/pushy) 3 | 4 | A Clojurescript library for quick and easy HTML5 pushState. 5 | 6 | ## Install 7 | 8 | [![Clojars Project](http://clojars.org/kibu/pushy/latest-version.svg)](http://clojars.org/kibu/pushy) 9 | 10 | ## Usage 11 | 12 | ### Setup 13 | 14 | You can construct a new instance by calling the `pushy` function. 15 | 16 | `pushy` takes in two arguments: 17 | 18 | * `dispatch` fn: gets called when there is a match 19 | * `match` fn: checks if the path matches any routes defined. 20 | 21 | Optionally, you can specify an `:identity-fn` which parses and returns the route based on the result of the `match` fn. 22 | 23 | ### Event listeners 24 | 25 | You can start the event listeners with the `start!` method. 26 | 27 | This adds an event listener to all `click` events, which dispatches on all matched routes. 28 | Bypasses on Alt, Shift, Meta, Ctrl keys and middle clicks. 29 | 30 | The `stop!` method will tear down all event listeners of the pushy instance. 31 | 32 | ### Routing libraries 33 | 34 | pushy should work with any routing library: 35 | 36 | [Secretary](https://github.com/gf3/secretary) 37 | 38 | ```clojure 39 | (ns foo.core 40 | (:require [secretary.core :as secretary :include-macros true :refer-macros [defroute]] 41 | [pushy.core :as pushy])) 42 | 43 | (secretary/set-config! :prefix "/") 44 | 45 | (defroute index "/foo" [] 46 | (.log js/console "Hi")) 47 | 48 | (def history (pushy/pushy secretary/dispatch! 49 | (fn [x] (when (secretary/locate-route x) x)))) 50 | 51 | ;; Start event listeners 52 | (pushy/start! history) 53 | ``` 54 | 55 | [Bidi](https://github.com/juxt/bidi) 56 | 57 | ```clojure 58 | (ns foo.core 59 | (:require [bidi.bidi :as bidi] 60 | [pushy.core :as pushy])) 61 | 62 | (def state (atom {})) 63 | 64 | (def app-routes 65 | ["/" {"foo" :foo}]) 66 | 67 | (defn set-page! [match] 68 | (swap! state assoc :page match)) 69 | 70 | (def history 71 | (pushy/pushy set-page! (partial bidi/match-route app-routes))) 72 | 73 | (pushy/start! history) 74 | ``` 75 | 76 | [Silk](https://github.com/DomKM/silk) 77 | 78 | ```clojure 79 | (ns foo.core 80 | (:require [domkm.silk :as silk] 81 | [pushy.core :as pushy])) 82 | 83 | (def state (atom {})) 84 | 85 | (def app-routes 86 | (silk/routes [[:foo [["/foo"]]]])) 87 | 88 | (defn set-page!

[match] 138 | (assoc state :page match)) 139 | 140 | (def routes 141 | {[:get "/home" :home]}) 142 | 143 | (defn match-uri [uri] 144 | (:route-handler (sibiro/match-uri (sibiro/compile-routes routes) uri :get))) 145 | 146 | (def history (pushy/pushy set-page! match-uri)) 147 | 148 | (pushy/start! history) 149 | ``` 150 | 151 | ### URL handling 152 | 153 | By default pushy will dispatch on all relative URLs and absolute URLs that match the window's origin. This means that all external links will be bypassed. 154 | 155 | It is possible to specify which URLs are processable to pushy by specifying a custom predicate function `:processable-url?` in the constructor. This function is passed a single argument which is an instance of `goog.URI`. 156 | 157 | ### goog.history.HTML5History methods 158 | 159 | You can set the history state manually by calling the `set-token!` method. This will call the `dispatch` fn on a successfully matched path. 160 | 161 | Example: 162 | 163 | ```clojure 164 | (set-token! history "/foo") 165 | 166 | (get-token history) 167 | ;; => /foo 168 | ``` 169 | 170 | Likewise, you can call `replace-token!` which will also call the `dispatch` fn and replace the current history state without affecting the rest of the history stack. 171 | 172 | ## License 173 | 174 | Copyright © 2017 175 | 176 | Distributed under the Eclipse Public License either version 1.0 177 | -------------------------------------------------------------------------------- /project.clj: -------------------------------------------------------------------------------- 1 | (defproject kibu/pushy "0.3.8" 2 | :description "HTML5 pushState for Clojurescript" 3 | :url "https://github.com/kibu-australia/pushy" 4 | :license {:name "Eclipse Public License" 5 | :url "http://www.eclipse.org/legal/epl-v10.html"} 6 | 7 | :dependencies [[org.clojure/clojure "1.8.0" :scope "provided"] 8 | [org.clojure/clojurescript "1.9.494" :scope "provided"]] 9 | 10 | :aliases {"deploy" ["do" "clean," "deploy" "clojars"] 11 | "test" ["do" "clean," "with-profile" "dev" "cljsbuild" "test"]} 12 | 13 | :lein-release {:deploy-via :shell 14 | :shell ["lein" "deploy"]} 15 | 16 | :source-paths ["src"] 17 | 18 | :profiles {:dev {:dependencies [[secretary "1.2.1"]] 19 | :plugins [[lein-cljsbuild "1.1.5"] 20 | [com.cemerick/clojurescript.test "0.3.3"]] 21 | 22 | :cljsbuild 23 | {:test-commands 24 | {"unit" ["phantomjs" :runner 25 | "target/unit-test.js"]} 26 | :builds 27 | {:test {:source-paths ["src" "test"] 28 | :compiler {:output-to "target/unit-test.js" 29 | :optimizations :whitespace 30 | :pretty-print true}}}}}}) 31 | -------------------------------------------------------------------------------- /src/pushy/core.cljs: -------------------------------------------------------------------------------- 1 | (ns pushy.core 2 | (:require [goog.events :as events] 3 | [clojure.string]) 4 | (:import goog.History 5 | goog.history.Html5History 6 | goog.history.Html5History.TokenTransformer 7 | goog.history.EventType 8 | goog.Uri)) 9 | 10 | (defn- on-click [funk] 11 | (events/listen js/document "click" funk)) 12 | 13 | (defn- update-history!
