How to escape a # in velocity

Question

I would like to know how can i escape a # in velocity. Backslash seems to escape it but it prints itself as well

This:

\#\#

prints:

\#\#

I would like:

##

Note that as of 2012 at least, you can now escape things in Velocity with backslash: \# and \$. See http://velocity.apache.org/engine/devel/user-guide.html#Getting_literal — Steven, Feb 17 '12 at 18:06

this:

#[[
##
]]#

will yield:

##

anything within #[[ ... ]]# is unparsed.

Exactly what I needed! The above code generates `\n##\n` though, so just use `#[[##]]#` if you don't want empty lines before and after the `##`. – adentinger Jun 02 '22 at 22:19

If you don't want to bother with the EscapeTool, you can do this:

#set( $H = '#' )
$H$H

That's what I used when I needed it, the escape tool is kind of clunky – Ruan Mendes Jan 11 '12 at 18:03
I think this always works, unrelated with versions of velocity. – hudidit Nov 13 '17 at 12:36

Add the esc tool to your toolbox and then you can use ${esc.hash}

The set technique is a good way to get around any characters you need escaping, like if you want to have $name followed by "_lastname" then you can do:

set ($n = '_lastname)

and have this in your template:

$name$n

and it's all good.
