Description

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:

3) Command Script
