Claude Brisson commented on VELOCITY-901:
-----------------------------------------
> Does it work if you put curlies around the variable name?
No. And probably not easy to integrate in the parser. Certainly not very
consistent, and maybe not worth it for backward compatibility, since it still
requires a templates review.
> hyphen in identifiers cause parse error

> Key: VELOCITY-901
> URL: https://issues.apache.org/jira/browse/VELOCITY-901
> Project: Velocity
> Issue Type: Bug
> Components: Engine
> Affects Versions: 2.0
> Reporter: Mark Newton
> Assignee: Claude Brisson
> Priority: Major
> Fix For: 2.0
>
> Attachments: err, example2.vm.snip, run.sh
>
>
> Upon upgrading to Velocity 2.0 from a very old version (1.4), hyphens in
> identifiers in templates throw a ParseException.
> To verify what was happening, I did a clean install of velocity 2.0 to test
> your example code. After running the unmodified "example2.vm" successfully I
> added an identifier with a hyphen and the parse error occurred.
> Apologies if I am missing something (e.g. spec change on identifiers). If
> this is an issue that will take a while to fix, please let me know so that I
> can change out the hyphens to underbars in id's in my template sets.
> Attached are: 1) code snippet 2) parse exception msg 3) cl used to invoke
> velocity 2.0 upon example2.vm
> Best Regards
> --------------------
> 1) code snippet
> #set($test-var-w-hyphen = "test")
> test-var-w-hyphen : $test-var-w-hyphen
> ------------------------------
> 2) Parse exception
> [main] ERROR org.apache.velocity.parser - example2.vm: Encountered "-" at
> line 20, column 11.
> Was expecting one of:
> "[" ...
> <WHITESPACE> ...
> <NEWLINE> ...
> "=" ...
> --------------------------
> 3) Command Script
> #/bin/bash
