python - 如何在 python 中从 perforce check out 文件？

Question

我想用 python 编写一些脚本，对源代码进行一些自动更改。如果脚本确定它需要更改文件，我想首先从 perforce 中检查它。我不关心 checkin ，因为我总是想先构建和测试。

Perforce 在其 C/C++ 工具周围有 Python 包装器，以二进制形式提供给 Windows，并为其他平台提供源代码:

您会发现他们的脚本 API 文档很有用:

Python API 的使用与命令行客户端非常相似:

PythonWin 2.5.1 (r251:54863, May  1 2007, 17:47:05) [MSC v.1310 32 bit (Intel)] on win32.

>>> import P4
>>> p4 = P4.P4()
>>> p4.connect() # connect to the default server, with the default clientspec
>>> desc = {"Description": "My new changelist description",
...         "Change": "new"
...         }
>>> p4.input = desc
>>> p4.run("changelist", "-i")
['Change 2579505 created.']
>>> 

我将从命令行验证它:

P:\>p4 changelist -o 2579505
# A Perforce Change Specification.
#
#  Change:      The change number. 'new' on a new changelist.
#  Date:        The date this specification was last modified.
#  Client:      The client on which the changelist was created.  Read-only.
#  User:        The user who created the changelist.
#  Status:      Either 'pending' or 'submitted'. Read-only.
#  Description: Comments about the changelist.  Required.
#  Jobs:        What opened jobs are to be closed by this changelist.
#               You may delete jobs from this list.  (New changelists only.)
#  Files:       What opened files from the default changelist are to be added
#               to this changelist.  You may delete files from this list.
#               (New changelists only.)
