Crate coloursum

🎨 Colourise your checksum output

Coloursum provides several line formatters capable of being produced from a line of various checksum generators' output, in order to colourise or otherwise transform their checksum in order to improve readability.

Formatting one line with the Line trait

Types implementing Line understand both the BSD "tag" form, as well as the GNU Coreutils/Perl shasum(1) form of checksums, and have been tested with the output from macOS' md5, shasum, as well as GNU md5sum and sha256sum.

They emit their formatted contents when Displayed to a user, with macros like format! or writeln!:

use coloursum::EcojiLine;

// BSD "tag" form
let bsd_line = EcojiLine::from("MD5 (./src/ecoji_line.rs) = 841d462b66e1f4bb839a1b72ab3f3668".to_string());

assert_eq!(
    format!("{}", bsd_line),
    "MD5 (./src/ecoji_line.rs) = 📢💥👛🤓🤴🛌😫🥊🌵🚦😚🚲👱☕☕☕"
);

// GNU Coreutils/Perl form
let gnu_line = EcojiLine::from("841d462b66e1f4bb839a1b72ab3f3668  ./src/ecoji_line.rs".to_string());

assert_eq!(
    format!("{}", gnu_line),
    "📢💥👛🤓🤴🛌😫🥊🌵🚦😚🚲👱☕☕☕  ./src/ecoji_line.rs"
);

Formatting a buffer of lines with the coloursum function

The Line trait implements a coloursum function. This consumes a BufRead input buffer, and writes formatted lines to a Write output buffer.

use std::io::BufReader;

use coloursum::{Line, EcojiLine};
use indoc::indoc;

// Note that each line will have its format detected separately, so
// BSD and GNU form lines can be in the same buffer
let input = indoc!("
    MD5 (./src/ecoji_line.rs) = 841d462b66e1f4bb839a1b72ab3f3668
    841d462b66e1f4bb839a1b72ab3f3668  ./src/ecoji_line.rs
").as_bytes();

let input_buffer = BufReader::new(input);
let mut output_buffer: Vec<u8> = Vec::new();

EcojiLine::coloursum(input_buffer, &mut output_buffer);

assert_eq!(
    std::str::from_utf8(&output_buffer).unwrap(),
    indoc!("
        MD5 (./src/ecoji_line.rs) = 📢💥👛🤓🤴🛌😫🥊🌵🚦😚🚲👱☕☕☕
        📢💥👛🤓🤴🛌😫🥊🌵🚦😚🚲👱☕☕☕  ./src/ecoji_line.rs
    ")
);
