Crate rlsp_fmt 

A Wadler-Lindig pretty-printing engine.

Build a Doc tree that describes the structure of your output, then let the printer decide where to break lines based on the available width. The core idea: group marks a subtree as a flat/break decision boundary — the printer tries to render it on one line and falls back to multi-line only when the content would exceed FormatOptions::print_width.

Quick start

use rlsp_fmt::{Doc, concat, group, indent, line, text, format, FormatOptions};

// Build a document: "[" <items> "]"
let doc = group(concat(vec![
    text("["),
    indent(concat(vec![line(), text("a"), text(","), line(), text("b")])),
    line(),
    text("]"),
]));

let opts = FormatOptions { print_width: 80, ..Default::default() };
assert_eq!(format(&doc, &opts), "[ a, b ]");

// Narrow width forces the group to break.
let opts_narrow = FormatOptions { print_width: 5, ..Default::default() };
assert!(format(&doc, &opts_narrow).contains('\n'));

See FormatOptions for all rendering controls.
