commitlint not working for git submodules

[ericcornelissen]

When working with git submodules, commitlint cannot find the COMMIT_EDITMSG file for the submodule and you get an error (see below for details).

Expected Behavior

Commitlint should look for the COMMIT_EDITMSG file located in the parents .git folder.

Current Behavior

Commitlint errors with the following error:

Error: ENOENT: no such file or directory, open 'D:\Workspace\Demeter\modules\template-parser\.git\COMMIT_EDITMSG'

Affected packages

• cli
• core
• prompt
• config-angular

Possible Solution

Somehow check if the current repository is a submodule and if that is the case look at the .git folder of the parent repository instead. The parents .git folder can be found in the .git file of the submodule.

Steps to Reproduce (for bugs)

1. Create a git repository
2. Add a submodule to the git repository created in step 1.
3. Make sure the submodule uses commitlint.
4. Try to lint the commit message for a commit in the submodule.

commitlint.config.js (of the submodule)

```js module.exports = { extends: ['@commitlint/config-conventional'] }; ```

Context

I'm basically just trying to use commitlint in a project where I'm using submodules...

Your Environment

Executable	Version
commitlint --version	7.1.0
git --version	git version 2.6.1.windows.1
node --version	v8.3.0

I'd like to 👍 on this as it stems to a larger problem of not being able to run the CLI anywhere. It assumes you are running it from within a .git repo in the same level. That doesn't hold true. For example, I'm looking to run this on a pre-receive hook for GitHub at my company. Because the context for that doesn't have a .git folder, I can't run it properly. If there is a solution to this problem, it would hit two birds with one stone.

@Aghassi If you pass the message from stdin to commitlint it will not try to find a git root.

Thank for reporting thr original issue, I‘ll have a look

@marionebl Would you mind giving an example? In my experience doing something as simple as commitlint -e "this will fail" does not work as intended with commitlint installed globally via yarn. I've also tried echoing the content into a variable and then passing the variable to commitlint -e. That way complained about the missing .git folder. I can make a separate issue if you'd like to track it separately from this. I figured the two were related.

"fix: does not fail" | commitlint should do the trick. The docs could be clearer about this I guess.
