Christopher Schultz commented on VELOCITY-614:
----------------------------------------------
Aah... right. I keep forgetting that escaping is not really a part of Velocity.
You can put a backslash in front of a $ symbol to prevent it from being
evaluated, and you can put a backslash in front of a # symbol (in a directive
only) and that will prevent it from being executed (including parameters passed
to the directive).
This simply violates the principle of least surprise: all "escaping" is really
just special cases that look like traditional escaping.
It's also surprising to me that:
\#if($jazz)
Vyacheslav Ganelin
\#end
Yields:
#if($ jazz )
Vyacheslav Ganelin
#end
...rather than
#if([whatever $jazz evaluates to)
Vyacheslav Ganelin
#end
Not a complaint per-se, but something to think about when the parser is
re-written: escaping should work as expected by, say, a C programmer ;)

> Key: VELOCITY-614
> URL: https://issues.apache.org/jira/browse/VELOCITY-614
> Project: Velocity
> Issue Type: Bug
> Affects Versions: 1.6
> Environment: I don't think it is relevant but still: CPU Intel
> Pentium D, windows XP SP3, JRE 1.6.0_07, Velocity 1.6-beta1
> Reporter: Guillaume Polet
> Priority: Minor
> Fix For: 1.6

> Attachments: Velocity614TestCase.java

> "#something(Stuff)" in your templates (without the double quotes) causes a
> parse error.
> "\#something(Stuff)" in your template (without the double quotes) renders as
> "\#something(Stuff)"
> Either the first line should go through just fine, or the next one should not
> render the '\'
> This typically happens when you try to generate JavaDoc for overriding
> methods.
> Don't hesitate to contact me if this is not clear enough or if you are unable
> to reproduce this issue.
