我找到了一个示例 python 脚本并对其进行了修改,以便在提交前检查评论。我的问题是 python 解析的注释文本总是以空白结尾。

我将变量的打印输出添加到错误消息中以进行调试。
令人讨厌的是,如果我使用 bat 文件命令,事情似乎工作正常:
pre-commit.bat 仅检查空白提交消息:
@echo off
:: Stops commits that have empty log messages.
@echo off
setlocal
rem Subversion sends through the path to the repository and transaction id
set REPOS=%1
set TXN=%2
rem line below ensures at least one character ".", 5 characters require change to "....."
C:\SVN\bin\svnlook.exe log %REPOS% -t %TXN% | findstr . > nul
if %errorlevel% gtr 0 (goto err) else exit 0
:err
echo. 1>&2
echo Your commit has been blocked because you didn't enter a comment. 1>&2
echo Write a log message describing the changes made and try again. 1>&2
echo Thanks 1>&2
exit 1
我究竟做错了什么?
