Working with repositories
-------------------------
To update the repositories used by Gluon, just adjust the commit IDs in `modules` and
rerun
::
make update
`make update` also applies the patches that can be found in the directories found in
`patches`; the resulting branch will be called `patched`, while the commit specified in `modules`
can be refered to by the branch `base`.
After new patches have been commited on top of the `patched` branch (or existing commits
since the base commit have been edited or removed), the patch directories can be regenerated
using
::
make update-patches
If applying a patch fails because you have changed the base commit, the repository will be reset to the old `patched` branch
and you can try rebasing it onto the new `base` branch yourself and after that call `make update-patches` to fix the problem.
Always call `make update-patches` after making changes to a module repository as `make update` will overwrite your
commits, making `git reflog` the only way to recover them!
Development Guidelines
----------------------
lua should be used instead of sh whenever sensible. The following criteria
should be considered:
- Is the script doing more than just executing external commands? if so, use lua
- Is the script parsing/editing json-data? If so, use lua for speed
