如何强制 ag 在 node_modules 中查找匹配项？

Question

我正在使用 ag 来搜索 git repo。它在我的node_modules 子目录下找不到匹配项。为什么不呢，我该如何控制这种行为？

Answer 1

事实证明，默认情况下，ag 尊重 .gitignore 文件的内容。所以如果node_modules 在.gitignore 中，ag 就不会搜索它。这都是明智的行为，但如果您不期待它，则很难调试。希望这篇文章会有所帮助。

man ag结尾有一个很好的总结：

IGNORING FILES

   By default, ag will ignore files whose names match patterns in  .gitig-
   nore,  .hgignore,  or  .agignore.  These  files  can be anywhere in the
   directories being searched.  Ag  also  ignores  files  matched  by  the
   svn:ignore property if svn --version is 1.6 or older. Finally, ag looks
   in $HOME/.agignore for ignore patterns. Binary  files  are  ignored  by
   default as well.

   If  you want to ignore .gitignore, .hgignore, and svn:ignore, but still
   take .agignore into account, use -U.

   Use the -t option to search all text files; -a to search all files; and
   -u to search all, including hidden files.

就我的目的而言，ag -t 似乎运作良好。
