PHP code analyzer, similar to eslint, but with a focus on readability. The idea is to build an analyzer that can guarantee long term code maintainability for a project. The main project values are extendibility, ease of use, speed of analysis and simplicity.

quick links: Rules and default configuration

Installation and Usage

You can install readable using npm:

$ npm install @officient/readable --save-dev

You can get the help on useage:

$ npx readable --help

You should then set up a configuration file:

$ npx readable --init

After that, you can run readable on any file or directory like this:

$ npx readable

You can also add it to your NPM scripts:

"scripts": {
    "test": "readable"
},

 $ npm run test

Exit code

Configuration

After running readable --init, you'll have a .readable.json file in your directory. In it, you'll see some rules configured like this:

{
  "paths": [
    "src/",
    "!src/vendor/"
  ],
  "rules": {}
}

Start a path with ! to ignore the folder.

Baseline

If you have a bunch of errors and you don't want to fix them all at once, readable can ignore errors in existing code, while ensuring that new code doesn't have errors:

$ npx readable --save-base-line .baseline.json

will generate or update .baseline.json file containing the current errors. Add "baseline" param to your .readable.json:

{
  "baseline": ".baseline.json",
  "..."
}

You can commit the changes so that readable running in other places (e.g. CI) won't complain about those errors. If you want to see all errors run with --disable-base-line flag:

$ npx readable --disable-base-line

Rules

See Rules and default configuration for default rules. Or read how to create a custom rule.
