一种验证.gitignore文件的方法 [英] A way to validate .gitignore file

问题描述

有没有一种方法可以验证.gitignore文件，以便您快速找到double路径或不再存在的路径?通常，当一个项目很小时，这并不是真正必要的，但是由于很多分支和.gitignore文件的合并，这可以在手.

Is there a way to validate a .gitignore file so you quickly find doubles paths or paths that don't exist anymore? Normally when a project is small this isn't really necessary but with lots of branches and mergings of .gitignore files this can come in hand.

推荐答案

不完全是.
一个可能接近的命令是 git check-ignore

Not exactly.
One command which could come close would be git check-ignore

选择一个您应该忽略的文件，然后检查以下内容的输出:

Choose a file you know is supposed to be ignored, and check the output of:

git check-ignore -v -- /path/to/ignored/file

您将看到.gitignore的适用规则.

2016年3月更新:Git 2.8将添加一种调试.gitignore文件及其规则的新方法.

Update March 2016: Git 2.8 will add a new way to debug .gitignore files and their rules.

在允许子文件夹不被忽略的情况下(即使其父文件夹被忽略)，请参见:此宝石，它是 href ="https://github.com/pclouds" rel ="noreferrer">吴恩达(pclouds):

In the context of allowing a sub-folder to not be ignored (even if its parent folder is ignored: see example here), I have found this gem by Thái Ngọc Duy (pclouds):

dir.c:支持跟踪排除

dir.c: support tracing exclude

man git 包括:

GIT_TRACE_EXCLUDE:

启用有助于调试.gitignore处理的跟踪消息.
有关可用跟踪的信息，请参见'GIT_TRACE'输出选项.

Enables trace messages that can help debugging .gitignore processing.
See 'GIT_TRACE' for available trace output options.

将GIT_TRACE_EXCLUDE设置为1，您将看到(在git status之后)标准调试器调试消息，例如:

With GIT_TRACE_EXCLUDE set to 1, you will see (after a git status) stderr debug messages like:

exclude: from ...
exclude: xxx => n/a
exclude: xxx vs. yyy at line z: => www
