How do I escape a subversion keyword?
I'm working on some software (spamassassin) that uses the subversion
keyword "$LastChangedDate$". In the same file that it's used, I want that
string to appear unmodified - not expanded by subversion, exactly as
"$LastChangedDate$" instead of something like "$LastChangedDate: 2010-03-30
08:02:18 -0400 (Tue, 30 Mar 2010) $"
Because I want to check for a case where svn keywords aren't getting
expanded.
Something like (perl):
if ('$LastChangedDate$' eq '$LastChangedDate$')
But with one of them getting expanded, and the other not.
I think it would work to do something like:
if ('$LastChangedDate$' eq '$LastChan'.'gedDate$')
But I'd prefer to escape the keyword instead.
Maybe something like \$LastChangedDate$ ?
The reason is that the Ubuntu daily build system on launchpad.net doesn't
support subversion keyword expansion:

Doesn't work. svn either expands them all, or none. The only way to
get selective is to use some quoting that does not affect the target
language's perception of the string but makes it not look like $Keyword$
to svn.
I don't know if perl likes
if ('$LastChangedDate\$' eq '$LastChangedDate$')
or
if ('$LastChangedDate\044' eq '$LastChangedDate$')
is legal in perl but anyway this specific check is equivalent to (Ruby)
if '$LastChangedDate$' =~ /:/
(check whether the string contains a colon).
Or, to answer the subject line: As by the escaping rules of your content language.

I want the expanded keyword, and the *un-expanded* keyword to both exist in
the same file.
So after expansion, it would look like:
if ('$LastChangedDate$' eq '$LastChangedDate: 2010-03-30 08:02:18 -0400 (Tue, 30 Mar 2010) $')
And when expansion doesn't happen (with launchpad build recipes), it'll
look like:
if ('$LastChangedDate$' eq '$LastChangedDate$')

How about:
if (length('$LastCheckedDate$') == 17) # keyword wasn't expanded

I'm confused about what you are asking. Are you saying you don't want subversion to expand the keywords? If so, then remove them from the svn:keywords property. Any keywords not in the property are not expanded.
