May 2018 Monthly Update

Clojurists Together news

Not much to report from Clojurists Together this month, things have been pretty quiet with lots of other things going on. This is the first month of work from the second round of funding. Bozhidar Batsov is working on CIDER + related projects and Mike Fikes is working on ClojureScript. If you like the work that they’re doing and would like to support it further, consider joining yourself or your company as a member.

CIDER updates

May 1 - 15

• Finished the nREPL migration out of clojure-contrib (the 0.4.0 marks the end of the breaking changes)
• Provided a PR for reply to switch to the new nREPL
• Migrated drawbridge to the new org and updated it for nREPL 0.4
• Extracted the var-info functionality from cider-nrepl to orchard
• Added basic cljs deps injection to CIDER on cider-jack-in-cljs

May 16 - 31

• Extracted the bencoding from nREPL into a library we hope to make portable
• Improved Clojure’s dependency checking a bit to be aware of group ids and versions
• Fixed a couple of small nREPL issues
• Started work on lein/boot plugins to boot the new nREPL from cider-jack-in

ClojureScript updates

May 1 - 15

The last couple of weeks saw this activity in the ClojureScript compiler:

• Patch landed for CLJS-2702, allowing the ClojureScript compiler (or end users) to upgrade to the latest Closure Library. The patch was written in such a way that end users can continue to use the current Closure Library, or upgrade to the latest, with the compiler codebase being compatible with both. You can read more details on this work at this gist
• Patch landed for highly-voted CLJS-2724, which will allow native Node modules (like “fs”) to be used in scripts executed via cljs.main
• Towards improving the use of :npm-deps, patch landed for CLJS-2739, which improves the performance of the compiler when indexing the node_modules directory. A test exhibited a 6-fold speedup, cutting the indexing time down from 30 seconds to 5 seconds.

Please continue to vote for, or file issues in the ClojureScript JIRA. I’m especially interested in those related to NPM dependency management.

May 16-31

The last couple of weeks saw this activity in the ClojureScript compiler:

• Submitted a patch in CLJS-2298, which causes REPLs to load any user-defined user.cljs / user.cljc file.
• Worked on CLJS-2651, which allows Git Deps to be supported in the AOT cache feature. Follow up work will be needed to sort out a corner case: CLJS-2765.
• Landed a patch for CLJS-1677 which was causing an issue if you explicitly require goog in ns forms in an :advanced build.
• Landed a patch in CLJS-2755, that makes it possible to generate values satisfying uri? when generatively testing with Spec.
• Landed a patch in CLJS-1871, which allows static dispatch to declared functions when hinted with :arglists meta. A bonus side effect is that it helps catch arity errors for calls to declared functions.
• Began investigation into CLJS-2339 and discovered they are no longer reproducible with latest compiler.
