Code Formatter for Sublime Text

A plugin that allows applying code formatting with minimum configuration.

Includes support for running the following formatters:

• Ruby’s RuboCop
• Ruby’s rubyfmt
• ESLint
• Prettier
• Golang’s gofmt
• Golang’s goimports
• Python’s autopep8
• Python’s yapf
• PHP Code Standards Fixer
• Rust’s rustfmt
• SVGO
• Flutter
• Dart’s dartfmt
• Crystal

Installation

Setup Package Control Repository

1. Follow the instructions from https://sublime.fnando.com.
2. Open the command pallete, run “Package Control: Install Package“, then search for “Codefmt“.

Git Clone

Clone this repository into the Sublime Text “Packages” directory, which is located where ever the “Preferences” -> “Browse Packages” option in sublime takes you.

Usage

By default, Codefmt is ran whenever you save a supported code file (i.e. a formatter is configured and enabled). You can disable this behaviour by changing the settings under “Sublime Text -> Preferences -> Package Settings -> Codefmt -> Settings” or by using the command palette (super+shift+p) and searching for “Codefmt: Settings”.

You can also trigger commands using the command pallete by searching for “Code Formatter: Format File”. You can add a custom shortcut by using the following command:

[{ "keys": ["super+k", "super+f"], "command": "format_code_file" }]

When auto saving is disabled, you can set up alternative keybindings so you can use super+s to save and format the current file, and another shortcut to bypass auto formatting. The following keybindings show how to do that for macOS:

[
  {
    "keys": ["super+s"],
    "command": "format_code_file"
  },
  {
    "keys": ["ctrl+s"],
    "command": "save",
    "args": { "async": true }
  }
]

Add new formatters

You add new formatters or override the settings for an existing one. All you have to do is a new key that identifiers the formatter to formatters, and the related configuration using the same key. So, let’s say you want add a formatter called txtfmt. The user configuration file could be something like this:

{
  overrides: {
    txtfmt: {
      // The command that will be executed for format files.
      // The special variables are:
      //
      // - `$config`: the full path to the configuration file we found.
      // - `$file`: the full path to the file that’s being formatted.
      command: ["txtfmt", "--fix", "--config", "$config", "$file"],

      // The scopes that will be considered when formatting
      scopes: ["text.plain"],

      // Additional flags when running in debug mode.
      // If the formatter doesn’t have a debug mode, you may set this to an empty
      // array.
      debug: ["--debug"],

      // When no custom config file exists, use a default config file.
      default_config: null,

      // Config files that will be looked up on the root of the project.
      // If the formatter doesn’t require a config file (or is automatically
      // inferred by the formatter), you may want to set this to an empty array.
      config_files: ["txtfmt.config.json"],
    },
  },

  formatters: ["gofmt", "rubocop", "prettier", "eslint", "txtfmt"],
}

Note

When overriding existing commands, you only need to define the keys that are changing; there's no need to add all options.

Using version managers

If you use version managers like asdf, you may need to set the command to the full path. The following example shows how to override RuboCop's command to use the shim:

{
  "overrides": {
    "rubocop": {
      "command": [
        "/Users/fnando/.asdf/shims/rubocop",
        "--auto-correct-all",
        "--config",
        "$config",
        "$file"
      ]
    }
  }
}

Note

Commands are always executed from the root directory of your project.

Some commands may require additional environment variables, like ASDF's golang plugin and the ASDF_GOLANG_MOD_VERSION_ENABLED environment variable. You can use the setting env to specify that.

Using .sublime-project files

You can override any setting per project. Here's an .sublime-project example:

{
  "folders": [
    {
      "path": "/home/fnando/example"
    }
  ],

  "settings": {
    "Codefmt": {
      "env": {
        "ASDF_GOLANG_MOD_VERSION_ENABLED": "true"
      },
      "debug": true,
      "formatters": ["gofmt"]
    }
  }
}
