[16:34] <jonathon> is it possible to alter source build recipe substitution variables? e.g. I have a latest-tag that starts with a letter (v) that i'd like to strip out to leave just the following version number (v1 -> 1)
[19:10] <jonathon> i can't see a way of doing it. ideally it would allow e.g. {latest-tag[1:]} as it's python-based, but that's not a valid input for the function
[19:44] <jonathon> bzr-builder does support `run` which might have helped, but running arbitrary stuff in a shell isn't enabled on Launchpad for obvious reasons
[21:10] <jonathon> meh... workaround is to add a hard-coded prefix then add the tag later in the version number, e.g. 1.0+{latest-tag}-0 -> 1.0+v1.0.67-0 . It's not ideal but it will do
