Template, as in file template?

So TM_PROJECT_DIRECTORY/FILEPATH would probably also have the 
/Volumes/WorkDisk-prefix?

I.e. _including_ the last path of the project location?

You probably want to use 'sed' which can do single-line 
regex-substitutions, e.g. if I enter and select these three lines in 
TextMate:

echo $TM_FILEPATH
echo $TM_PROJECT_DIRECTORY
echo $TM_FILEPATH | sed "s|^$TM_PROJECT_DIRECTORY/\(.*\)\$|\1|"

And press control-r, they return:

/tmp/myProject/untitled.txt
/tmp/myProject
untitled.txt

So the first two are just the variables, the third is the TM_FILEPATH 
but w/o the TM_PROJECT_DIRECTORY-prefix [1]

But in your case, you'd preferred it to be 'myProject/untitled.txt' ?

sed is probably what you want, but feel free to ask any followup 
questions (but provide as much context as possible).


Kind regards Allan

[1] before beta 5 I didn't run the project file/directory through 
stringByStandardizingPath, so e.g. /tmp would be /private/tmp etc.
