Overview

P4CMD 🌴

A Python Perforce package that doesn't bring in any other packages to work. Relies on p4cli installed on the system.

p4cmd

The p4cmd module holds the P4Client class that allows you to interact with the P4 server.

To instantiate a new client, you either pass it the root path of you Perforce workspace or if the "P4ROOT" system variable is set, you can use the from_env class function

from p4cmd import p4cmd

client = p4cmd.P4Client("~/nisse/projects/raw")

from p4cmd import p4cmd
import os

# settings system variable
os.environ["P4ROOT"] = "~/nisse/projects/raw"

# now we can use from_env
client = p4cmd.P4Client.from_env()

Most of the functions are pretty self explanatory and have docstrings about how they work.

There are 2 functions called file_to_p4files and folder_to_p4files that use the P4File class in p4file.

p4file

This module holds the P4File class that allows you to quickly and easily get information about any file on disk or in the depot.

Usage

Some use case examples to help you on your way.

Checking out files or adding new files. You can mix/match local and depot paths. Add a changelist number or description to put the files in that CL. If you add a description of a changelist that doesn't exist, it will be created.

from p4cmd import p4cmd
root = "~/p4/MyGame"

files = [r"~/p4/MyGame/Raw/Characters/info_file.json",
         "//MyGame/Main/Templates/morefiles.json"]

p4 = p4cmd.P4Client(root)
p4.add_or_edit_files(files, changelist="My new changelist")

Seperate edit_files and add_files methods also exist if you need to use them for some reason.

Perforce operations can be quite slow, so if you need to check a bunch of files at once you can use do something like this:

from p4cmd import p4cmd
root = "~/p4/MyGame"

folder = r"~/p4/MyGame/Animations"

p4 = p4cmd.P4Client(root)
p4files = p4.folder_to_p4files(folder)

files_to_sync = []
for p4file in p4files:
    if p4file.get_checked_out_by() is not None: # somebody else other than you checked out the file
        print("depot path:", p4file.get_depot_file_path())
        print("local path:", p4file.get_local_file_path())
        print("status:", p4file.get_status())
        print("Checked out by:", p4file.get_checked_out_by())
    if p4file.needs_syncing():
        files_to_sync.append(p4file.get_local_file_path())

p4.sync_files([files_to_sync])

depot path: //MyGame/Main/MyGame/run.fbx
local path: ~/p4/MyGame/MyGame/run.fbx
status: UP_TO_DATE
Checked out by: [email protected]
depot path: //MyGame/Main/MyGame/dance.json
local path: ~/p4/MyGame/MyGame/dance.json
status: NEED_SYNC

folder_to_p4files returns a list of type p4file. A p4file has a bunch of functions to get information about the file and its status. This will get information back about all the files in one go, instead of you having to make a server call for every file on its own.

Getting all your pending changelists:

from p4cmd import p4cmd
root = "~/p4/MyGame"

p4 = p4cmd.P4Client(root)
all_changelists = p4.get_pending_changelists()

[35272, 33160, 32756, 30872, 27277]

Getting changelists with shelved files:

from p4cmd import p4cmd
root = "~/p4/MyGame"

p4 = p4cmd.P4Client(root)
shelved_changelists = [pair[1] for pair in p4.get_shelved_files()]

[30872, 30872, 27277]

Searching in changelist descriptions:

from p4cmd import p4cmd
root = "~/p4/MyGame"

p4 = p4cmd.P4Client(root)
houdini_cls = p4.get_pending_changelists(description_filter="houdini")

[35272, 33160]

Finding an exact changelist:

from p4cmd import p4cmd
root = "~/p4/MyGame"

p4 = p4cmd.P4Client(root)
houdini_anim_cl = p4.get_pending_changelists(description_filter="[houdini tools]", perfect_match_only=True, case_sensitive=True)

[33160]

Listing all the files in a changelist by changelist number:

from p4cmd import p4cmd
root = "~/p4/MyGame"

p4 = p4cmd.P4Client(root)
files = p4.get_files_in_changelist(33160)

//MyGame/Animations/a_pose.fbx
//MyGame/Animations/t_pose.fbx

List all the files in a changelist by changelist description:

from p4cmd import p4cmd
root = "~/p4/MyGame"

p4 = p4cmd.P4Client(root)
files = p4.get_files_in_changelist("[houdini tools]")

//MyGame/Animations/a_pose.fbx
//MyGame/Animations/t_pose.fbx

Comments

New functions & validation function
Added new validate files under perforce root function that raises error if files not under root

Removed default list arg for folder sync function

Added a delete changelist function

Added a revert changelist function (gets all files in a CL and reverts them all)

10C Patches

Raising exception when files are not under client root Adding is_under_client_root validation check in p4_file Setting list for files inputted to function is not list
