uber-dot-arcanist

This product encapsulates any arcanist plugins we depend on at Uber that are not included with arcanist itself. With this repo, you can avoid copypasta plugin folders in the .arcanist folder at the root of your project that are likely to be out of date.

Included Arcanist Plugins

Currently, this module contains three arcanist plugins:

• tap
• uber-standard
• lint-trap (deprecated)

Usage

To use this module, follow these steps from the root of your project:

# first make sure you have the most recent version of arcanist
arc upgrade

# install uber-dot-arcanist as a dev-dependency
npm install --save-dev uber-dot-arcanist

# if you currently have a .arcanist/ folder in your project, check it to make
# sure that is doesn't include any plugins that uber-dot-arcanist doesn't
# include.
# Legacy Uber projects may have tap, jenkinsphoo and jshintlinter. This module
# contains only the tap plugin as usage of the other two are deprecated at Uber.
ls -al .arcanist

# if there are no folders or directories in .arcanist besides jenkinsphoo, tap
# or jshintlinter, you can delete .arcanist. If there are any other modules,
# follow the instructions in the section 'How to handle other plugins in
# .arcanist'
git rm -rf .arcanist

After removing the .arcanist folder, you need to configure arcanist to load the plugins from the node_modules/uber-dot-arcanist/.arcanist/ folder.

Open your .arcconfig file and look for the load property. It is likely to be an array like so:

{
    "load": [".arcanist/tap", "arcanist/uber-standard"]
}

If you see jshintlinter or jenkinsphoo in the array, you can delete those elements. For tap, you just need to prepend the path to the .arcanist folder in this module. Assuming your load value was the one right above, your new values would be:

{
    "load": [
        "node_modules/uber-dot-arcanist/.arcanist/tap",
        "node_modules/uber-dot-arcanist/.arcanist/uber-standard"
    ]
}

To add support for uber-standard when submitting differentials to Phabricator with arc diff, you can add the following to your .arclint file.

{
    "linters": {
        "uber-standard": {
            "type": "uber-standard",
            "include": "(\\.js$)"
        }
    }
}

Once you've made these changes just stage your changes and commit:

git add package.json
git add .arclint
git add .arcconfig
git commit -m "Loading arcanist plugins from uber-dot-arcanist npm module"

How to handle other plugins in .arcanist

If you encounter a plugin in your .arcanist folder that is not either tap or uber-standard, you should first check the [phacility/arcanist][arcrepo] to see if the plugin you are using is already part of the standard arcanist install. If it is not, git clone this repo and add the plugin to this repo to make it available to other engineers at Uber. Don't forget to add the repo to the section titled "Included Arcanist Plugins" at the top of this README.

Tests

This module is just a wrapper around arcanist plugins. It is not callable as a library and contains no binary file. The tests just check that the expected plugins are included and that this module throws if called programmatically.
