This tool for formatting .slint syntax is in a very early stage. There might be certain parts of the language that are not yet supported. If you find any such examples, please open an issue including the example and the expected output.

Use cargo build --release or similar to build this crate.

The built binary can be used in following ways:

• slint-fmt <path> - reads the file and outputs the formatted version to stdout
• slint-fmt -i <path> - reads the file and saves the output to the same file
• slint-fmt /dev/stdin - using /dev/stdin you can achieve the special behavior of reading from stdin and writing to stdout

Note that .slint files are formatted, while .md and .rs files are searched for .slint blocks. All other files are left untouched.

While we don't yet have a proper VSCode integration for this formatter, here is a simple way how you can get around it.

1. Install the extension Custom Format by Vehmloewff. Marketplace link
2. Build slint-fmt locally.
3. Add a section like this to your vscode settings.json:

{
  "custom-format.formatters": [
    {
      "language": "slint",
      "command": "/path/to/your/built/slint-fmt /dev/stdin"
    }
  ]
}

4. (Optional) Allow formatting or save, or set this formatter as default for .slint files.
5. Enjoy! Your .slint files are now formatted.
