| 3 | +## Running Athens Locally |
| 4 | + |
| 5 | +[Video version of this for Mac](https://www.loom.com/share/63618f2a2b2249e3923577fb88fabfdc). |
| 6 | + |
| 7 | +These dependencies are needed to get Athens up and running. To install them, follow the instructions in the links. |
| 8 | + |
| 9 | +1. [Java 11 and Leiningen](https://purelyfunctional.tv/guide/how-to-install-clojure/) \(Leiningen installs Clojure\) |
| 10 | +2. [Node 12](https://nodejs.org/en/download/) and [Yarn](https://classic.yarnpkg.com/en/docs/install/#mac-stable) |
| 11 | + |
| 12 | +_If you want to use Windows Subsystem for Linux \(WSL\),_ [_try this tutorial_](https://www.notion.so/Beginner-Clojure-Environment-Setup-Windows-36f70c16b9a7420da3cd797a3eb712fa#6a53854de58d4f07ba6319d868fba29c)_._ |
| 13 | + |
| 14 | +After you've got these dependencies, clone the Git repository to your hard drive: |
| 15 | + |
| 16 | +```text |
| 17 | +git clone https://github.com/athensresearch/athens.git |
| 18 | +``` |
| 19 | + |
| 20 | +Then `cd athens/` and run the following commands. |
| 21 | + |
| 22 | +Pull JavaScript dependencies: |
| 23 | + |
| 24 | +```text |
| 25 | +yarn |
| 26 | +``` |
| 27 | + |
| 28 | +Pull Java dependencies and build, then start a local HTTP server for Athens: |
| 29 | + |
| 30 | +```text |
| 31 | +lein dev |
| 32 | +``` |
| 33 | + |
| 34 | +In another terminal, run: |
| 35 | + |
| 36 | +```text |
| 37 | +yarn run electron . |
| 38 | +``` |
| 39 | + |
| 40 | +Another window should open automatically. That's your Athens! |
| 41 | + |
| 42 | +Now make sure you can run code in a REPL and that you know how to use re-frame-10x. |
| 43 | + |
| 44 | +### Running in Docker |
| 45 | + |
| 46 | +Docker doesn't work perfectly well anymore, because we are using Electron. Electron requires access to local resources such as `resources/index.html`. |
| 47 | + |
| 48 | +If you run `yarn run electron .` from your local system, but are running Athens from within Docker, it won't work. Furthermore, if you run `yarn run electron .` from within your Docker system, the GUI won't popup on your local system. The workaround would be to sync the `resources/` files from Docker to a local folder. |
| 49 | + |
| 50 | +The following command runs Athens in a docker container, but does not provide a workaround to actually run Electron. |
| 51 | + |
| 52 | +```text |
| 53 | +docker build -t athens . |
| 54 | +docker run -it -p 3000:3000 -p 8777:8777 -p 9630:9630 athens |
| 55 | +``` |
| 56 | + |
| 57 | +## Deploying Athens and Devcards |
| 58 | + |
| 59 | +You should deploy your version of Athens and [Devcards](https://github.com/bhauman/devcards) if you are making UI-releated pull requests to Athens. This will allow developers and designers to interact with your code, which is essential for reviewing UI changes. |
| 60 | + |
| 61 | +Athens Devcards can be found at [https://athensresearch.github.io/athens/cards.html](https://athensresearch.github.io/athens/cards.html). |
| 62 | + |
| 63 | +### Automated Deploys |
| 64 | + |
| 65 | +We've setup GitHub Actions so that each time you commit to your fork on GitHub, GitHub Actions automatically lints, tests, and styles your code. |
| 66 | + |
| 67 | +If these scripts pass, GitHub builds your code and then deploys it to [https://YOUR\_GITHUB.github.io/athens/](https://YOUR_GITHUB.github.io/athens/) and [https://YOUR\_GITHUB.github.io/athens/cards.html](https://YOUR_GITHUB.github.io/athens/cards.html). |
| 68 | + |
| 69 | +To begin doing automated deploys, just make sure your Actions are enabled at [https://github.com/YOUR\_GITHUB/athens/actions](https://github.com/YOUR_GITHUB/athens/actions). Then start pushing code! |
| 70 | + |
| 71 | +### Manual Deploys |
| 72 | + |
| 73 | +To build and deploy Athens and Devcards from your local development environment: |
| 74 | + |
| 75 | +1. Build your JavaScript bundle\(s\) with either `lein dev`, `lein devcards`, or `lein compile`. |
| 76 | +2. Run `lein gh-pages`. |
| 77 | +3. Open [http:///github.io/athens/](http:///github.io/athens/) and [http:///github.io/athens/cards.html](http:///github.io/athens/cards.html). Sometimes this takes a minute to be updated. |
| 78 | + |
| 79 | +Notes: |
| 80 | + |
| 81 | +* If you want to compile Athens and Devcards one time without hot-reloading, run `lein compile`. |
| 82 | +* If you are actively developing Athens and not Devcards, run `lein dev` to hot-reload the Athens application. |
| 83 | +* If you are actively developing DevCards and not Athens, run `lein devcards` to hot-reload Devcards. |
| 84 | +* If you want to build Athens and Devcards, because you are testing a component on DevCards and Athens at the same time, you should run `lein dev` and `lein devcards` in two terminals. |
| 85 | +* If both builds are running, it doesn't matter which port you go to \(i.e. `3000` or `3001`\), because both HTTP servers can serve assets. |
| 86 | +* More docs should be written in the future on how to connect a REPL to either build, depending on your text editor. |
| 87 | + |
| 88 | +## Connecting your REPL |
| 89 | + |
| 90 | +The REPL is one of the core features of Clojure. REPL-driven programming can make you code faster, with less tests and bugs. This [video](https://vvvvalvalval.github.io/posts/what-makes-a-good-repl.html#what_does_a_good_repl_give_you?:~:text=What%20does%20a%20good%20REPL%20give%20you%3F,-The) demonstrates this. |
| 91 | + |
| 92 | +* Make sure you can run Athens locally before proceeding with this section. |
| 93 | +* Refer to shadow-cljs [editor integration docs](https://shadow-cljs.github.io/docs/UsersGuide.html#_editor_integration) for more details. |
| 94 | +* nREPL port is 8777, as defined in [shadow-cljs.edn](shadow-cljs.edn). |

| 104 | +### Calva |
| 105 | + |
| 106 | +```text |
| 107 | +Editor - Visual Studio Code |
| 108 | +Calva plugin: v2.0.126 Built on: 2020-07-09 |
| 109 | +OS - Windows 10, MacOS Catalina v10.15.6 |
| 110 | +``` |
| 111 | + |
| 112 | +1. In VS Code, run `ctrl+shift+c` and `ctrl+shift+j` \(`ctrl+alt+c ctrl+alt+j` in Windows 10\) to jack into a repl session. |
| 113 | +2. Pick shadow-cljs. |
| 114 | +3. Select `:main` and `:renderer` profile for shadow-cljs to watch. |
| 115 | +4. Select the `:renderer` build to connect to. |
| 116 | +5. In another terminal tab, run `npx electron .` |
| 117 | + |
| 118 | +### Vim Plugins |
| 119 | + |
| 120 | +* [ ] TODO vim-iced |
| 121 | +* [ ] TODO conjure |
| 122 | +* \[X\] TODO fireplace |
| 123 | + |
| 124 | +#### Fireplace |
| 125 | + |
| 126 | +[Fireplace](https://github.com/tpope/vim-fireplace) is a popular Clojure\(script\) development plugin for Vim \(and Neovim\) text editor. It's main dependency is the [cider-nrepl](https://github.com/clojure-emacs/cider-nrepl) which already included as a development dependency. |
| 127 | + |
| 128 | +Assume you already executed the commands described above in different terminal sessions and have the Athens instance running. And of course assume you installed vim-fireplace plugin too. |
| 129 | + |
| 130 | +```text |
| 131 | +lein dev # in one terminal, running nrepl server on port 8777 |
| 132 | +yarn run electron . # another terminal running the Athens app itself |
| 133 | +``` |
| 134 | + |
| 135 | +Now open any Clojure file in Vim. This will load vim-fireplace plugin and necessary commands. First, we need to connect Clojure \(not Clojurescript yet\) runtime; |
| 136 | + |
| 137 | +```text |
| 138 | +:FireplaceConnect 8777 |
| 139 | +``` |
| 140 | + |
| 141 | +Clojure part is done. Now to connect Clojurescript runtime with vim-fireplace; |
| 142 | + |
| 143 | +```text |
| 144 | +:Piggieback :renderer |
| 145 | +``` |
| 146 | + |
| 147 | +To test your development environment you can try to evaluate some Clojurescript and see the results on Athens running in electron; |
| 148 | + |
| 149 | +```text |
| 150 | +:CljsEval (js/alert "hello!") |
| 151 | +``` |
| 152 | + |
| 153 | +You supposed to see an alert on electron app saying "hello!" and your Vim instance would be blocked until you acknowledge the alert message. |
| 154 | + |
| 155 | +If all goes well, now you can see documentation of symbols \(binding: K\), go to definition \(binding: \[ C-d\) and so fort. See `:help fireplace` for more information. |
| 156 | + |
| 157 | +#### Conjure |
| 158 | + |
| 159 | +[Conjure](https://github.com/Olical/conjure) is an interactive environment for evaluating code within your running program for Neovim. [Installing Conjure](https://github.com/Olical/conjure#installation) |
| 160 | + |
| 161 | +Its main dependency is the [cider-nrepl](https://github.com/clojure-emacs/cider-nrepl). Create the following file at `~/.shadow-cljs/config.edn` to add the dependency: |
| 162 | + |
| 163 | +```text |
| 164 | +{:dependencies |
| 165 | + [[cider/cider-nrepl "0.26.0"]]} |
| 166 | +;; this version may be out of date, check whichever is available |
| 167 | +``` |
| 168 | + |
| 169 | +See [shadow-cljs docs](https://shadow-cljs.github.io/docs/UsersGuide.html#user-config) for more info. |
| 170 | + |
| 171 | +Now that we're set up, lets start the development environment; |
| 172 | + |
| 173 | +```text |
| 174 | +lein dev # in one terminal, running nrepl server on port 8777 |
| 175 | +yarn run electron . # another terminal running the Athens app itself |
| 176 | +``` |
| 177 | + |
| 178 | +Open any Clojurescript file in Neovim. Conjure will connect automatically to the leiningen nrepl server and you should see a temporary floating buffer in the top right corner of your editor showing a successful connection. |
| 179 | + |
| 180 | +To get that buffer back and to keep it open in a horizontal split: |
| 181 | + |
| 182 | +```text |
| 183 | +:ConjureLogSplit |
| 184 | +``` |
| 185 | + |
| 186 | +To connect to the Clojurescript runtime; |
| 187 | + |
| 188 | +```text |
| 189 | +:ConjureShadowSelect renderer |
| 190 | +``` |
| 191 | + |
| 192 | +In the log buffer you should see; |
| 193 | + |
| 194 | +```text |
| 195 | +; -------------------------------------------------------------------------------- |
| 196 | +; shadow-cljs (select): renderer |
| 197 | +; (out) To quit, type: :cljs/quit |
| 198 | +[:selected :renderer] |
| 199 | +``` |
| 200 | + |
| 201 | +To test your development environment you can try to evaluate some Clojurescript and see the results on Athens running in electron; |
| 202 | + |
| 203 | +```text |
| 204 | +:ConjureEval (js/alert "hello!") |
| 205 | +``` |
| 206 | + |
| 207 | +You should see an alert in the electron app saying "hello!". All further evaluations will be blocked until you acknowledge the alert message. |
| 208 | + |
| 209 | +Congratulations, you're connected! |
| 210 | + |
| 211 | +To learn more about how to evaluate things with Conjure, please refer to `:help conjure`, `:help conjure-client-clojure-nrepl` and `:ConjureSchool` \(an interactive tutorial\). See also: \[Conjures quickstart guide to Clojurescript\]\([https://github.com/Olical/conjure/wiki/Quick-start:-ClojureScript-\(shadow-cljs](https://github.com/Olical/conjure/wiki/Quick-start:-ClojureScript-%28shadow-cljs)\)\) and [Clojure](https://github.com/Olical/conjure/wiki/Quick-start:-Clojure) |
| 212 | + |
| 213 | +## Using re-frame-10x |
| 214 | + |
| 215 | +The right sidebar has [`re-frame-10x`](https://github.com/day8/re-frame-10x/tree/master/src/day8) developer tools. You can toggle it open and close with `ctrl-h`, but you must not be focused on a block \(ctrl-h has a specific action in some operating systems\). |
| 216 | + |
| 217 | +Once you have 10x open, you can hover over blocks' bullets to see some of their datascript data. |
| 218 | + |
| 219 | +By default, 10x is closed everytime Athens starts. Sometimes you want 10x to be open immediately on start. To do, comment out the two lines of JavaScript code in `index.html`, where localStorage sets 10x to be closed by default. |
| 220 | + |
| 221 | +## Running CI Scripts Locally |
| 222 | + |
| 223 | +After each submitted PR to Athens, GitHub Actions runs the continuous integration workflow declared in `.github/workflows/build.yml`. This workflow runs scripts from [`script/`](script) to test, lint, and build Athens. You can see these workflows in practice in the [Actions tab](https://github.com/athensresearch/athens/actions/). |
| 224 | + |
| 225 | +However, it's a lot faster if you run these tests locally, so you don't have to submit a PR each time to make sure the workflow succeeds. You may need to install additional dependencies, though. |
| 226 | + |
| 227 | +### Testing |
| 228 | + |
| 229 | +No additional installation is needed. Just run this: |
| 230 | + |
| 231 | +```text |
| 232 | +lein test |
| 233 | +``` |
| 234 | + |
| 235 | +The output will look something like this: |
| 236 | + |
| 237 | +```text |
| 238 | +$ lein test |
| 239 | +
|
| 240 | +Testing athens.block-test |
| 241 | +
|
| 242 | +Testing athens.parser-test |
| 243 | +
|
| 244 | +Testing athens.patterns-test |
| 245 | +
|
| 246 | +Ran 4 tests containing 16 assertions. |
| 247 | +0 failures, 0 errors. |
| 248 | +``` |
| 249 | + |
| 250 | +### Linting |
| 251 | + |
| 252 | +We are linting Clojure code using [clj-kondo](https://github.com/borkdude/clj-kondo). Our clj-kondo configuration is in [`.clj-kondo/config.edn`](.clj-kondo/config.edn). |
| 253 | + |
| 254 | +For this linting to work, you will need to install `clj-kondo`. Instructions are in [`clj-kondo`’s installation guide](https://github.com/borkdude/clj-kondo/blob/master/doc/install.md). |
| 255 | + |
| 256 | +To see the problems reported by clj-kondo, run `script/lint`. Example run: |
| 257 | + |
| 258 | +```text |
| 259 | +$ script/lint |
| 260 | +linting took 257ms, errors: 0, warnings: 0 |
| 261 | +``` |
| 262 | + |
| 263 | +Your editor may also be able to integrate with clj-kondo’s output. For example, if you use [Calva](https://marketplace.visualstudio.com/items?itemName=betterthantomorrow.calva) for VS Code, then clj-kondo’s messages are reported in the Problems panel. |
| 264 | + |
| 265 | +### Clojure Styling |
| 266 | + |
| 267 | +To format your code or check that your code is formatted correctly, you will need to use `cljstyle`. Instructions for installing it are [in `cljstyle`’s README](https://github.com/greglook/cljstyle/tree/master#installation). |
| 268 | + |
| 269 | +To check if your Clojure code is formatted correctly, run `cljstyle check`. If there is no output and the return code is zero, you’re good. You can also run `script/style`, but currently it only works if you’re running Linux. |
| 270 | + |
| 271 | +To reformat all your Clojure files in place, run `cljstyle fix`. |
| 272 | + |
| 273 | +### Unused Variable Checking |
| 274 | + |
| 275 | +To set this up, first make sure that a global `clojure` binary is installed. You won’t necessarily have a `clojure` binary installed just because you installed Leiningen. |
| 276 | + |
| 277 | +Next, just run `script/carve`. The first time you run it it will download [Carve](https://github.com/borkdude/carve) as a dependency, which takes about a minute and outputs lots of messages. On subsequent runs `script/carve` won’t output anything unless an unused variable was found. |
| 278 | + |
