在Mercurial和Git中为JSLint预先提交钩子 [英] Pre Commit Hook for JSLint in Mercurial and Git

问题描述

我希望在提交Mercurial或Git仓库之前运行JSLint。

I want to run JSLint before a commit into either a Mercurial or Git repo is done.

我希望这是一个自动设置的步骤，而不是依赖对开发者（主要是我）记得在手之前运行JSLint。我通常在开发过程中运行JSLint，但是希望在JS文件上指定一个合同，以便在提交到repo之前通过JSLint。

I want this as an automatic step that is set up instead of relying on the developer (mainly me) remembering to run JSLint before-hand. I normally run JSLint while developing, but want to specify a contract on JS files that they pass JSLint before being committed to the repo.

对于Mercurial，这个页面说明了预先提交的语法，但似乎可用的唯一变量是提交中涉及的parent1和parent2变更集ID。我真正想要的是与提交有关的文件名列表，以便我可以选择.js文件并在其上运行jslint。

For Mercurial, this page spells out the precommit syntax, but the only variables that seem to be available are the parent1 and parent2 changeset IDs involved in the commit. What I really want are a list of file names that are involved with the commit, so that I can then choose the .js file and run jslint over them.

GIT的类似问题，作为预提交脚本一部分提供的默认信息似乎有限。

Similar issue for GIT, the default info available as part of the precommit script seems limited.

可能的工作是调用hg status / git status作为预提交脚本的一部分，解析输出以查找JS文件，然后以此方式完成工作。尽管我希望能够更容易，但我不确定是否将状态作为预提交钩子的一部分反映了正确的信息。例如在Git中，如果尚未添加更改文件，但git commit使用-a，那么这些文件是否会在git status输出的正确部分显示为提交集的一部分？

What might work is calling hg status/git status as part of the precommit script, parse that output to find JS files then do the work that way. I was hoping for something easier though, and I am not sure if calling status as part of a precommit hook reflect the correct information. For instance in Git if the changes files have not been added yet, but the git commit uses -a, would the files show up in the correct section of the git status output as being part of the commit set?

推荐答案

对于git， .git / hooks目录。如果您只需要JSLint的文件名，您可以使用 git diff --name-only ，在我的示例中它将列出与当前不同的文件名 HEAD 。

For git, there are examples in the .git/hooks directory. If you just need the file names for JSLint, you could use git diff --name-only, which in my example will list the names of the files that differ from the current HEAD.
