Thomas Mortagne commented on VELOCITY-901:
------------------------------------------

bq. his was very confusing for newcomers. Do you really think you want them 
back?!

I agree but on my side the issue is how to deal with retro compatibility. Such 
a change is a major breakage (even if documented).

> hyphen in identifiers cause parse error

>                 URL: https://issues.apache.org/jira/browse/VELOCITY-901
>             Project: Velocity
>          Issue Type: Bug
>          Components: Engine
>    Affects Versions: 2.0
>            Reporter: Mark Newton
>            Priority: Major
>         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")

> ------------------------------
> 2) Parse exception

>  <NEWLINE> ...
>  "=" ...
> --------------------------
> 3) Command Script
