Wist is a linter for identifying and reporting errors in Brightscript code. It helps you identify errors before you upload code to your Roku.

For full documentation, please see our user and developer guides here

Wist has one of the most accurate and complete implementations of the Brightscript grammer available right now. It focuses reporting not just syntax violations, but reporting patterns that are likely to result in errors.

• NodeJS

• (Optional) JDK8

The easiest and best way to use Wist, is through our editor clients.

• Atom IDE Brightscript
• VSCode coming soon

You can install them through their respective package managers and work out of the box with a .wistrc.json in your root directory.

We recommend taking this approach if you if you want to include Wist as part of your project's build pipeline. Wist is available via as an NPM package and can be installed like so:

$ npm install -g @willowtreeapps/wist

It can be invoked directly using the wist command

$ wist yourfile.brs

Wist can also be installed locally to the project

$ npm install @willowtreeapps/wist --save-dev

After that, you can run Wist in your project's root directory like this:

$ ./node_modules/.bin/wist yourfile.brs

To get started linting your Brightscript project, you should then setup a wist configuration file:

$ wist --init

This will generate a .wistrc.json file in your directory. In it, you'll see some rules configured like this:

{
    "rules": {
        "no-stop": ["error"],
        "no-print": ["warn"]
    }
}

These configures the sort of errors that the rules engine reports back. There are several other rules that can be configured. See the documentation for the full list.

Once your .wistrc.json has been configured to your liking. Invoke wist on your Brightscript file.

$ wist yourfile.brs
