prim-fmt

The formatting engine behind prim — an opinionated, near-zero-config formatter for a repository's connective tissue (Markdown, JSON/JSONC, YAML, TOML) plus whitespace hygiene.

This crate is the pure library: strings in, strings out, no CLI or terminal dependencies, so other tools can embed it. The prim binary is published separately as prim-cli.

Status: early. classify + format apply the whitespace-hygiene pass to the parsed formats and the orphan allowlist; structured per-format passes land in later milestones. See the specification.

Usage

use std::path::Path;

// Classify a file by name, then format its contents for that kind.
if let Some(kind) = prim_fmt::classify(Path::new("README.md")) {
    let formatted = prim_fmt::format(kind, "# Title  \n");
    assert_eq!(formatted, "# Title\n");
}
