TextBlocks

A simple crate for parsing text blocks. Can be used to parse text files with blocks of data separated by blank lines. Works well with \n or \r\n line endings.

Contains the TextBlocks trait which adds the methods as_blocks, block_parse_lines and block_parse to str and String.

Install

Run the following command in your project directory:

bash cargo add textblocks

Or add the following to your Cargo.toml:

toml [dependencies] textblocks = "0.1.0"

Note: Check the crates.io page for the latest version.

Examples

• Parse a block into a vector of lines

rust use textblocks::*; let s = "100\n200\n\n300\n400\n\n500\n600"; assert_eq!(s.as_blocks(), vec![vec!["100", "200"], vec!["300", "400"], vec!["500", "600"]]); assert_eq!(s.as_blocks(), [["100", "200"], ["300", "400"], ["500", "600"]]);

• Parse a block into a vector of lines, where each line is parsed into a number (u32)

rust use textblocks::*; let s = "100\n200\n\n300\n400\n\n500\n600"; let result = s.block_parse_lines(|line| line.parse::<u32>().unwrap()); assert_eq!(result, [[100, 200], [300, 400], [500, 600]]);

• Parse a block into a vector of lines, where each line is parsed into a number (u32), and then sum the numbers

rust use textblocks::*; let s = "100\n200\n\n300\n400\n\n500\n600"; let result = s.block_parse( |line| line.parse::<u32>().unwrap(), |block| block.iter().sum::<u32>() ); assert_eq!(result, [300, 700, 1100]);
