Instead of adding every program's directory to my system PATH, I prefer having
|
|
a single directory on my PATH which contains Windows shortcuts (lnk files)
|
|
pointing to each program.
|
|
Windows lnks are different from softlinks because they maintain the program's
|
|
real directory necessary for loading nearby dlls etc.
|
|
However, this breaks `shutil.which` --> `subprocess.run` because subprocess.run
|
|
with shell=False does not interpret lnks, and needs a direct path to the exe.
|
|
|
|
So, this module provides a function `which` that if it finds an lnk file, will
|
|
return the exe path, otherwise behaves the same as normal shutil which.
