Project description
ShellContexts
A few useful context managers for temporarily changing the environment.
ModificationContext
`- chdir
`- set_umask
`- increase_umask
`- decrease_umask
`- seteuid
`- setegid
They are simple wrappers around the syscalls in their names. Therefore they are not thread-safe, so use them sanely. They are however reentry safe :)
chdir serves the same purpose as contextlib.chdir. It is here for completion-ist sake, and to demonstrate the abstraction provided by ModificationContext.
We decided to not add the rest to the standard library, in shutil or contextlib, whence I decided to make this package.
