Mercurial pre commit hook - 根据文件内容停止提交？

Question

如何设置预提交 Hook ，它将在提交的文件中搜索字符串，如果找到则停止提交？

Answer 1

Chapter 10的 the mercurial book准确地涵盖了这一点:

$ cat .hg/hgrc
[hooks]
pretxncommit.whitespace = hg export tip | (! egrep -q '^\+.*[ \t]$')
$ echo 'a ' > a
$ hg commit -A -m 'test with trailing whitespace'
adding a
transaction abort!
rollback completed
abort: pretxncommit.whitespace hook exited with status 1
$ echo 'a' > a
$ hg commit -A -m 'drop trailing whitespace and try again'

In this example, we introduce a simple pretxncommit hook that checks for trailing whitespace. This hook is short, but not very helpful. It exits with an error status if a change adds a line with trailing whitespace to any file, but does not print any information that might help us to identify the offending file or line. It also has the nice property of not paying attention to unmodified lines; only lines that introduce new trailing whitespace cause problems.

只需将正则表达式从 '^\+.*[ \t]$' 更改到您正在寻找的任何字符串。
