Question

p4.exe is the perforce command line tool (git/cvs/svn like tool).
I am trying to launch several ms-dos commands ‘p4 resolve’ in an python script. because I have a hundred files to resolve.

However I cannot launch ‘p4 resolve -m’ as I want (which automatically opens my 3-way merge tool on the conflicting files). p4 doesn’t accept the m as an executable parameter.

Instead, manually, I must do ‘p4 resolve’, then wait for the prompt to ask me for an option, and then only type ‘m’ there.

Do you know in python how I could feed the input since I cannot pass the ‘m’ parameter to the command line tool p4.exe.

For the moment I use os.system(myDosCommand)

Answer 1

Something like…

from subprocess import Popen

resolve = Popen(["p4", "resolve"])
stdout, stderr = resolve.communicate("m")
