commitlint ignores commit messages starting with hashtag "#"

Expected Behavior

commitlint -e fails when type is not present and a hashtag is used at the beginning of the commit message

Current Behavior

commitlint -e succeeds when omitting a type and using a hashtag at the beginning of the commit message

Affected packages

• cli
• core
• prompt
• config-angular

Possible Solution

Is a # maybe interpeted as a comment, and thus succeeds?

Steps to Reproduce (for bugs)

We have a .husky/pre-commit file with the following contents

#!/bin/sh
. "$(dirname "$0")/_/husky.sh"

commitlint -e

Our .commitlintrc.json looks like this

{
  "extends": ["./node_modules/@commitlint/config-conventional"],
  "rules": {
    "subject-case": [0],
    "type-enum": [2, "always", ["feat", "fix", "chore"]],
    "header-max-length": [0, "always", 120],
    "body-max-line-length": [0, "always", "Infinity"],
    "footer-max-line-length": [0, "always", "Infinity"]
  }
}

Using this configuration, writing in CLI

git commit -m "foo: bar" leads to

$ commitlint -e
⧗   input: foo: bar
✖   type must be one of [feat, fix, chore] [type-enum]

while git commit -m "#8299-fix-prettier" leads to

Done in 0.58s.
[feature/test 66676512] #8299-fix-prettier
 1 file changed, 111 insertions(+)
 create mode 100644 test.yml

My suspicion is that it’s somehow interpeted as comment? But shouldn’t it still fail, since we have the always rule case regarding the type.

Context

We are using azure devops, so in order to link workitems (tickets) to a commit, we used the commit message template #1234 Add foo before. We now switched to conventional commits and have a pre-commit hook.

However, some developers still need to adjust to these changes and accidentally commit with the wrong commit message. This shouldn’t be a problem, since we have pre-commit hooks, however the pre-commit hook is not triggered when using a hashtag as a commit message

Yes, makes sense! You also state that in the README.md so no worries! We now updated to v17.0.1 Thanks for this library and the quick support

[kobelobster]

I just confirmed, when using 17.0.1 this issue is resolved. Commiting with a message as described now leads to an error

$ commitlint -e
⧗   input: #8299-fix-prettier
✖   subject may not be empty [subject-empty]
✖   type may not be empty [type-empty]

✖   found 2 problems, 0 warnings

Since my bug was for an EOL version, I will close this issue as it is resolved and won’t be fixed. We updated our package to version 17.0.1
