SmartGit是否有办法设置和自动增量version numbers？
我读了一些关于标签的内容并在我的初始分支上设置了这个（到“5.7.0”）。我是否需要手动设置此标记，或者是否有一个插件可以在幕后为我处理版本控制？

Git不关心版本，只关注提交哈希。 ： - ）
我的解决方案是编写一对用作过滤器的脚本。 这些脚本查找$ Date $和$ Revision $关键字，并分别使用日期和版本（标记）扩展它们。
在我的~/.gitconfig文件中，我有以下内容;
[filter "kw"]
clean = kwclean
smudge = kwset
这些是脚本（用Python编写）

rrep = ''.join(['$', 'Revision', '$'])
for line in sys.stdin:
line = dre.sub(drep, line)
print rre.sub(rrep, line),
在存储库的.gitattributes文件中，我指定哪些文件应更新其关键字，例如：
*.py filter=kw
签入新版本后，我使用git tag设置版本号。然后我运行一个脚本来更新所有具有关键字的文件;
