[Scons-users] How can I manipulate $SOURCE and $TARGET

[Tom Tanner (BLOOMBERG/ LONDON)]

You could use something like $(TARGET.file} to get purely the filename, but I think you might have to provide your own function to get just the lowest level directory, somewhat like this (from 'variable substitution' in the man page)

def foo(target, source, env, for_signature):
tgt = str(target[0])
return os.path.join(os.path.basename(os.path.dirname(tgt)), os.path.basename(tgt))

env['FOO'] = foo

then in your LINKCOMSTR use $FOO rather than $TARGET

Using one of LINKCOMSTR or its variants to control the output of a build, I would like to strip some of the leading directories from the $SOURCE and $TARGET strings.  For example, if  $TARGET is

       /a/really/long/directory/path/to/package/file.exe

I would like to print just 

     package/file.exe

 and ignore the boilerplate root directories as just adding noise to the output.   

I am a novice at this, so hopefully I just missed the obvious.
