changelog

0.6.0

  • Fixed issue with 0.5.0 where either cljx or cljsbuild would be invoked multiple times in the course of a build when run under Leiningen >= 2.4.2. (gh-61)
  • Fixed issue where cljx would not be invoked despite inclusion of it in :prep-tasks. (gh-60)
  • Polling rate of cljx auto changed to 250ms (gh-46)

The first of the above fixes necessitated a change in how cljx folds into the Leiningen "lifecycle" (now it is a "pure" plugin, and does not use eval-in at all). This is technically a breaking change, in that any use of custom :rules in :cljx configuration resolved from project dependencies will break under 0.6.0. The fix is to either change project configuration and/or refactor the definition of such :rules vars such that they are added to the project as :plugin dependencies (rather than "regular" :dependencies dependencies). [Terminology fail :-/]

0.5.0

  • cljx hooks have been eliminated (their use only emits a warning now), due to upstream changes in Leiningen (gh-51, gh-49, gh-22)
  • cljx now depends upon a canonical release of sjacket, which eliminates various dependency resolution warnings
  • cljx auto will now only reprocess files that have changed (gh-53)

0.4.0

  • The cljx nREPL middleware has been enhanced to make running lein cljx once unnecessary when running a ClojureScript REPL. This means that e.g. (load-namespace 'ns.written.in.cljx) or (ns foo (:require ns.written.in.cljx)) will work, even if no corresponding .cljs file has been generated yet. (gh-24)
  • Updated the piggieback dependency to align with its range of compatibility with the ClojureScript compiler API (gh-40)

0.3.2

  • The cljx nREPL middleware has been enhanced to make running lein cljx once unnecessary when running a Clojure REPL. This means that e.g. (require 'ns.written.in.cljx) will work, even if no corresponding .clj file has been generated yet. (Analogous support for on-the-fly cljx transformations for ClojureScript is coming.) (gh-24)

0.3.1

  • cljx now includes a small bit of Leiningen middleware that will automatically configure your project to use cljx's nREPL middleware and Piggieback, eliminating the need to duplicate cljx as a dependency in your project.clj. (gh-26)
  • Clojure test files generated by cljx are now properly recognized as "eligible" for testing by Leiningen's lein test task (gh-19)

0.3.0

Mostly a rewrite to use sjacket, removing all dependency on the Clojure reader and thereby eliminating all of the issues that go along with it (e.g. lossy representation, line number changes when emitting Clojure[Script], issues like this, etc).

The syntax for annotations has changed, as described in the readme. tl;dr, all you need to do is s/\^:(cljs?)/#+$1/g. The only gotcha is that putting annotations on var symbols no longer supported (which carried a bunch of problems before anyway, but nevermind that); so, you have to change e.g. this:

(defn ^:cljs foo [x] (whatever x))

into:

#+cljs (defn foo [x] (whatever x))

Again, tl;dr: cljx annotations apply to expressions, and nothing else.

Otherwise, everything works as it did; even your existing project.clj configurations can stay as they are (though anything other than the three :build map keys described in the README are now superfluous).
