Chlorine

CircleCI

Cl + Atom = Chlorine

Socket-REPL integration with Clojure and ClojureScript with Atom.

This project also have a FAQ now

WARNING

This project is migrated to GitLab. This repository just exists because it needs to be on GitHub for publication to work. Updated documentation, etc, must be sent to GitLab only.

Example

Chlorine connects to a Socket REPL and adds autocomplete, goto var definition, evaluation, refresh, and documentation of functions on Atom. It can also add additional things, so check it out on extending Chlorine. The idea of the project is to give Atom a felling of being completely connected to running code that's being developed, like SmallTalk images but still working with textual source codes, git, and every other tool that we already use with our code.

Evaluating code

As it is possible to see above, Chlorine works both with Clojure and ClojureScript (only shadow-cljs for now).

Usage:

If you are new to Clojure or Atom, you may check this quickstart guide.

Fire up a clojure REPL with Socket REPL support. With

shadow-cljs
, when you
watch
some build ID it'll give you a port for nREPL and Socket REPL. With
lein
, invoke it in a folder where you have
project.clj
and you can use
JVM_OPTS
environment variable like (on Linux or MacOS):
JVM_OPTS='-Dclojure.server.myrepl={:port,5555,:accept,clojure.core.server/repl}' lein repl

On Windows, you can add a profile on

project.clj
that will add these JVM options; to do it, check if your
project.clj
have the
:profiles
key. If it does, just add the
:socket
part, if it does not, add the
:profiles
tag and then the
:socket
:
  ; ... dependencies, main, etc ...
  :profiles {:socket {:jvm-opts ["-Dclojure.server.myrepl={:port,5555,:accept,clojure.core.server/repl}"]}}

Then, you can run

lein with-profile +socket repl
, and it'll open a Socket REPL on port
5555
.

On Shadow-CLJS' newer versions, when you start a build with

shadow-cljs watch 
, it doesn't shows the Socket REPL port on the console, but it does create a file with the port number on
.shadow-cljs/socket-repl.port
. You can read that file to see the port number (Chlorine currently uses this file to mark the port as default).

With

clj
, you can run the following from any folder:
clj -J'-Dclojure.server.repl={:port,5555,:accept,clojure.core.server/repl}'

Or have it in

:aliases
in
deps.edn
. (For an example with port 50505 see https://github.com/seancorfield/dot-clojure/blob/master/deps.edn, then you can run
clj -A:socket
.)

Then, you connect Chlorine with the port using the command Connect Clojure Socket REPL. This package works with lumo too, but you'll need to run Connect ClojureScript Socket REPL.

When connected, it'll try to load

compliment
and
org.clojure/tools.namespace
(for autocomplete and refresh). Then you can evaluate code on it, and it'll render on a block decoration below the line.

Keybindings:

This package does not register any keybindings to avoid keybinding conflict issues. You can define whatever you want via keymap.cson. The following have worked for some people:

If you use vim-mode-plus: ```cson 'atom-text-editor.vim-mode-plus.normal-mode[data-grammar="source clojure"]': 'g f': 'chlorine:go-to-var-definition' 'ctrl-d': 'chlorine:doc-for-var' 'space c': 'chlorine:connect-socket-repl' 'space l': 'chlorine:clear-console' 'shift-enter': 'chlorine:evaluate-block' 'ctrl-enter': 'chlorine:evaluate-top-block' 'ctrl-c': 'chlorine:break-evaluation' 'space space': 'chlorine:clear-inline-results' 'space x': 'chlorine:run-tests-in-ns' 'space t': 'chlorine:run-test-for-var'

'atom-text-editor.vim-mode-plus.insert-mode[data-grammar="source clojure"]': 'shift-enter': 'chlorine:evaluate-block' 'ctrl-enter': 'chlorine:evaluate-top-block' ```

If you don't use vim bindings:

cson
'atom-text-editor[data-grammar="source clojure"]':
  'ctrl-; y':       'chlorine:connect-socket-repl'
  'ctrl-; e':       'chlorine:disconnect'
  'ctrl-; k':       'chlorine:clear-console'
  'ctrl-; f':       'chlorine:load-file'
  'ctrl-; b':       'chlorine:evaluate-block'
  'ctrl-; B':       'chlorine:evaluate-top-block'
  'ctrl-; i':       'chlorine:inspect-block'
  'ctrl-; I':       'chlorine:inspect-top-block'
  'ctrl-; s':       'chlorine:evaluate-selection'
  'ctrl-; c':       'chlorine:break-evaluation'
  'ctrl-; S':       'chlorine:source-for-var'
  'ctrl-; d':       'chlorine:doc-for-var'
  'ctrl-; x':       'chlorine:run-tests-in-ns'
  'ctrl-; t':       'chlorine:run-test-for-var'

How to work with ClojureScript

For now, it only works with Shadow-CLJS or ClojureScript implementations like Lumo or Plank that exposes a ClojureScript socket REPL.

With Lumo, you fire up lumo with

lumo -n 3322
to start a socket REPL on port
3322
(or any other port), then connect Chlorine with "Connect ClojureScript Socket REPL".

With Shadow-CLJS, after watching (or after starting a server, or anything that starts a socket REPL) you need to run the compiled javascript file in the output directory (configured in shadow-cljs.edn) - either with

node <...>
(if it's a node script) or by opening the browser in a page that includes the script (if you're targetting browser), connect with "Connect Socket REPL" (Chlorine will auto-detect the port - you don't need to change it), and run the command "Connect Embedded". Then you can run code on
.cljs
files too. For ClojureScript its also recommended to enable "experimental features" (on Chlorine settings) for better experience.

WARNING

Do not evaluate the

ns
form in Shadow-CLJS. Shadow keeps your namespaces reloaded all the time, and sometimes re-evaluating then can lead to strange issues. If you do evaluate the ns form and get errors, just save the current file and Shadow will hot-reload it, and things will be fine. For more info, see: https://github.com/mauricioszabo/atom-chlorine/issues/213

Detection

Chlorine will try to detect the current file extension, falling back to

.clj
if the file is not saved. With ClojureScript, it'll only evaluate
.cljs
files, and it'll use the Clojure REPL to evaluate
.clj
and
.cljc
files. You can override this behavior in the package's configuration to one of the following:
  • Prefer CLJ - The default configuration, will use the Clojure REPL to evaluate
    .clj
    and
    .cljc
    and it'll use the ClojureScript REPL to evaluate
    .cljs
  • Prefer CLJS - It will use the Clojure REPL to evaluate
    .clj
    and the ClojureScript REPL to evaluate
    .cljc
    and
    .cljs
  • CLJ - It'll use the Clojure REPL to evaluate all files
  • CLJS - It'll use the ClojureScripte REPL to evaluate all files

Contributors

How to contribute?

As Chlorine is in active development, it was starting to become tedious to publish a newer version of repl-tooling for every experiment, so for now, the library is registered as a submodule. To contribute, you clone this repository and run:

./scripts/setup

To register the submodule. More info on Developing document.
