Yes, as in a file template inside my own .tmbundle in AppSupport/TM/ 
dir. (Basically it's a copy of the "PHP Script" template in the default 
PHP.tmbundle in the TM app folder.

Yes, but TM_PROJECT points to the location where I have stored the TM 
.tmproj file, rather than to where the project - in my mind at least - 
is.

Yes, IF I understand your question correctly. What I want and assumed 
to be the case is that the top directory in the Project Drawer is the 
TM_PROJECT_DIRECTORY, but it's not really is it ?  Bit confused about 
what refers to what here and there.

Using the above outputs the following:

echo $TM_FILEPATH
echo $TM_PROJECT_DIRECTORY
echo $TM_FILEPATH | sed "s|^$TM_PROJECT_DIRECTORY/\(.*\)\$|\1|"
/Volumes/WorkDisk/Users/mats/Sites/projectName/index.php
/Volumes/WorkDisk/Users/mats/TextMateProjects
/Volumes/WorkDisk/Users/mats/Sites/projectName/index.php

echo $TM_PROJECT_DIRECTORY
echo $TM_PROJECT_FILEPATH
/Volumes/WorkDisk/Users/mats/TextMateProjects
/Volumes/WorkDisk/Users/mats/TextMateProjects/projectName.tmproj


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

Yes, however with the help of your suggestion and a bit of own brain 
activity - a rare but appreciated event - I created a work around for 
my system that works by using a custom shell variable that contains the 
path to the Sites directory.

echo $TM_SITES_DIRECTORY
/Volumes/WorkDisk/Users/mats/Sites

which then makes the following return exactly what I want

echo $TM_FILEPATH | sed "s|^$TM_SITES_DIRECTORY\(.*\)\$|\1|"
/projectName/index.php


So thanks to your help I have worked out/around the problem. THANK YOU 
!!


IMPORTANT:	Possible BUG ??

In the template I use ${TM_FILEPATH} and when I create a new template 
TM_FILEPATH takes the value of the currently selected Tab in the Tab 
bar. In other words. If I have "/tmp/index.php" as the active file in 
the main editor window, and then creates a new file that I name 
"newfile.php" the TM_FILEPATH output in the new file from the template 
is "/tmp/index.php" instead "/tmp/newfile.php" as it should be in my 
mind.

I really have to learn all the hidden shell stuff that's available in 
OS X now, as it can do much of great interest.

Do you have any recommendations about good resources for learning that 
stuff, books or online ? How did you grasp it all ?



Kind regards,
