如何忽略除.hgignore以外的所有目录? [英] How can I ignore all directories except one using .hgignore?

问题描述

我正在使用Mercurial管理$ HOME，以保持点文件的良好状态和可跟踪性，或者至少对我来说很重要.

I'm managing $HOME using Mercurial, to keep my dotfiles nice and tracked, or at least the ones that matter to me.

但是，〜中有大量的文件和目录不需要跟踪，并且该目录和目录不断变化和增长.

However, there's a profusion of files and directories in ~ that do not need to be tracked, and that set is ever-changing and ever-growing.

从历史上看，我已经通过使用以下.hgignore来解决了这个问题:

Historically, I've dealt with this by having this .hgignore:

syntax: glob
*

这将使我的状态保持尽可能的整洁，仅使以前跟踪的文件可见.但是，我有一些目录(在我的情况下为scripts，.emacs.d)，我希望在其中查看未跟踪的文件.我几乎总是要跟踪这些目录中的新内容.

This keeps my status clean, as far as it goes, making only previously tracked files visible. However, I have some directories (in my case, scripts, .emacs.d) that I would like to see untracked files in; I almost always want to track new additions to those directories.

我知道我可以运行hg st -u scripts来识别未跟踪的文件，但是我想要一种可以使用普通ole hg状态实现相同功能的方法.

I know that I can run hg st -u scripts to identify untracked files, but I want a means whereby I can achieve the same function using plain ole hg status.

有没有办法做到这一点?

Is there a way to do this?

推荐答案

请在.hgignore中尝试此操作:

syntax: regexp

^(?!(scripts|foo|bar)/)[^/]+/

• ^匹配路径的开头
• (?!(scripts|foo|bar)使用负前行忽略所有文件，但目录scripts，foo或bar
中的文件除外
• /)确保以跟踪目录作为前缀的目录被忽略
• [^/]+/然后实际上匹配任何目录(不包括先行排除的目录)，这样就不会忽略~中的文件
• ^ matches start of path
• (?!(scripts|foo|bar) uses negative lookahead to ignore all files except those in directories scripts, foo or bar
• /) ensures that directories which have a tracked directory as a prefix are ignored
• [^/]+/ then actually matches any directory (excluding those ruled out by the lookahead), so that files in ~ aren't ignored

此解决方案中的中心思想的信用(否定的前瞻性)归功于Michael La Voie对
