Crate snapper_fmt 

snapper

Semantic line break formatter for prose documents. Reformats text so each sentence occupies its own line, producing minimal git diffs when collaborating on papers and documentation.

The crate is published as snapper-fmt on crates.io; the binary it installs is called snapper.

Supported formats

• Org-mode: blocks, drawers, tables, keywords preserved
• LaTeX: preamble, math, environments, comments preserved
• Markdown: code blocks, front matter, headings preserved
• Plaintext: everything treated as prose

Library usage

use snapper_fmt::{format_text, FormatConfig};
use snapper_fmt::format::Format;

let input = "Hello world. This is a test. Another sentence.";
let config = FormatConfig {
    format: Format::Plaintext,
    max_width: 0,
    use_neural: false,
    extra_abbreviations: vec![],
};
let output = format_text(input, &config).unwrap();
assert_eq!(output, "Hello world.\nThis is a test.\nAnother sentence.");
