decamelize

Convert a camelCase string to a separated lower-case string.

fooBar → foo_bar, unicornsAndRainbows → unicorns_and_rainbows, XMLHttpRequest → xml_http_request. A faithful Rust port of the widely-used decamelize npm package.

• Zero dependencies, #![no_std]
• Custom separator and a preserveConsecutiveUppercase mode
• Differential-tested against the reference decamelize implementation

Install

[dependencies]
decamelize = "0.1"

Usage

use decamelize::{decamelize, decamelize_with};

assert_eq!(decamelize("unicornsAndRainbows"), "unicorns_and_rainbows");
assert_eq!(decamelize("testGUILabel"), "test_gui_label");
assert_eq!(decamelize("p2pNetwork"), "p2p_network");

// Custom separator:
assert_eq!(decamelize_with("fooBar", "-", false), "foo-bar");
assert_eq!(decamelize_with("unicornsAndRainbows", " ", false), "unicorns and rainbows");

// Preserve consecutive uppercase runs:
assert_eq!(decamelize_with("testGUILabel", "_", true), "test_GUI_label");
assert_eq!(decamelize_with("XMLHttpRequest", "_", true), "XML_http_request");
