redent

Strip redundant indentation and re-indent a string.

Removes the common leading indentation from a multi-line string, then indents it by a fixed amount — handy for normalizing then re-formatting heredoc/template text. A faithful Rust port of the widely-used redent npm package, built on strip-indent and indent-string.

• #![no_std]
• Differential-tested against the reference redent implementation

Install

[dependencies]
redent = "0.1"

Usage

use redent::{redent, redent_with};

// Strip the common indent (count defaults to 0):
assert_eq!(redent("  foo\n    bar"), "foo\n  bar");

// Strip, then re-indent by two spaces:
assert_eq!(redent_with("  foo\n    bar", 2, " ", false), "  foo\n    bar");

// Custom indent + indent empty lines:
assert_eq!(redent_with("  a\n\n  b", 2, " ", true), "  a\n  \n  b");
