Project setting for workingdir

[josh-j]

For some projects, you'll be in a directory that doesn't have the makefile and it makes no sense for turtlestein to execute commands there. A setting like shellturtlestein_workingdir in the project settings would solve that.

s = window.active_view().settings() if s.has("shellturtlestein_workingdir"): return s.get("shellturtlestein_workingdir")

in cwd_for_window will add that feature.

Alternatively, you could interpret the "cd" command for the shell-turtlestein's working directory. E.g., if I'm in C:\Test\src in turtlestein, I could type cd .. in turtlestein and move to the parent directory and execute commands there.

I like both ideas. We'd have to do some special handling of the cd command in order to persist the directory that was changed to for that window. I'd accept a patch
