[CLJ-433] munge should not munge $ (which isJavaIdentifierPart), should munge ' (which is not) Created: 09/Sep/10  Updated: 01/Mar/13  Resolved: 05/Jan/11

Approval: Ok


munge is overeager in converting $ to DOLLARSIGN, since $ is a valid
character in Java identifiers:

user> (filter #(Character/isJavaIdentifierPart %) (keys

On a related point, ' (single quote) is not admissible in Java
identifiers, but it is not munged on master:

user=> (Character/isJavaIdentifierPart \')
user=> (munge "'")

This leads to e.g.

user=> *'
#<core$_STAR_' clojure.core$_STAR_'@5adf48c4>

(note the ' after STAR).

Originally reported on the Dev list.

See also this thread on the (regular) Clojure ggroup.

The attached patch applies cleanly against current master.

Patch is clean, the real issue here is doing the right thing. Two concerns:

  • was the original choice to munge $ motivated, and if so do we need a more subtle patch that preserves that original intent?
  • presumably this is (yet another) binary-compatibility-breaking change. 1.3 already has major change, so now is a good a time as any...

This issue mentions two problems but patch fixes only one. Should add the single-quote handling

Right, I forgot about that in the patch somehow. Also, I just noticed that " is also not JavaIdentifierPart and yet is not currently munged. The newly attached patch fixes all three issues.
