Quick Escaping Question
Hello List,
I have a quick question about escaping characters. In a template I am
trying to output #. If I simply type #, nothing is printed out. The
manual talks about escaping $ with \$ but I did not see escaping the
pound sign anywhere. I tried the same technique with # (ie \#), but \
was printed out instead of the # I was expecting. Is it possible to
escape the pound character?
Thanks in advance,
Tim

I just happened to try the same thing earlier today and had no problem.
>From what I observed, as long as the # was not followed by an existing
directive (like #if), it was printed out directly. Otherwise, putting a
backslash in front of it escaped it just fine.
This is with Velocity 1.1.

Yep, I see it.
Thanks. Do the #set() workaround until I fix. Should be quick. Sorry
about this.

Re: Quick Escaping Question

Hello again,
Im still having the same problem trying to print a #.
I have tried to accomplish this with the following lines of code:
<td align=center class=v10><b>#</b></td>
<td align=center class=v10><b> # </b></td>
<td align=center class=v10><b>\#</b></td>
The first two render nothing and the third gives me a \.
The same thing happens if I replace the # with a $. I am trying to do
this within a #if statement within a #macro using version 1.2, if that
makes any difference.
Any thougths?
Thanks again,
Tim

A # should be printed out. What version of velocity are you using?

You only need to escape #<token> when <token> is a valid directive, like
\#set
Similarly, only need to escape $<foo> when <foo> is something that has a
value in the context.
Otherwise, all other cases should render 'as is'.
