Nim Debugging

I use GDB to debug my Nim code, but by default Nim doesn't output enough information to be usable. I pass --debuginfo --linedir:on to the nim command to fix that.

There is some name mangling, but in most cases things are still understandable. procs have an integer appended to the name, so when setting a breakpoint is done like this: b foo_431313. It's also possible to just line number for breakpoints, which is exactly as you might expect: b mymodule.nim:321.

Simple git-up

To install, download the script on your path, rename it to git-up and chmod +x git-up.

Usage is git up <remote> [params]. It iterates through all the the branches that exist on both local and the remote, and does git rebase $params $remote/$branch $branch. Really simple.

Dependencies are GNU Coreutils and git. Running linux? You'll have them both installed.
