regex-line-length is a linter for use with Phabricator's arc command line tool. This linter is able to identify lines that exceed a certain length while ignoring lines that match a list of regexes.

Add this repository as a git submodule.

git submodule init
git submodule add <url for this repo>

Your .arcconfig should list arc-regex-line-length-lint in the load configuration:

{
  "load": [
    "path/to/arc-regex-line-length-lint"
  ]
}

Clone this repository to the same directory where arcanist and libphutil are globally located. Your directory structure will look like so:

arcanist/
libphutil/
arc-proselint/

Your .arcconfig should list arc-regex-line-length-lint in the load configuration (without a path):

{
  "load": [
    "arc-regex-line-length-lint"
  ]
}

Create a .arclint file in the root of your project and add the following content:

{
  "line-length": {
    "type": "regex-line-length"
  },
}

Feel free to change the include/exclude regexes to suit your project's needs.

Line length can be configured by providing a max-line-length number:

{
  "line-length": {
    "type": "regex-line-length",
    "max-line-length": 100
  },
}

Lines can be ignored if they match a given list of regexes. In the following example we ignore lines that include a url.

{
  "line-length": {
    "type": "regex-line-length",
    "ignore-line-regexes": [
      "(https?://)"
    ]
  },
}
