sample_config.json5

// This is a JSON5 file, so you can use comments and trailing commas, which
// makes it a lot more convenient for configs.
// diffsitter looks for config files in
// ${XDG_HOME:-$HOME}/.config/diffsitter/config.json5 by default. You can
// override this behavior by passing the `--config` flag or setting the
// "DIFFSITTER_CONFIG" environment variable.
