Guix

Manipulate identifiers and structurally non-complex pieces of text by delimiting word boundaries via a combination of whitespace, control-characters, and case-sensitivity.

Has support for common idioms like casing of programmatic variable names, taking, dropping, and splitting by word, and modifying the first character of a piece of text.

Caution: this library makes heavy use of the text library's internal loop optimisation framework. Since internal modules are not guaranteed to have a stable API there is potential for build breakage when the text dependency is upgraded. Consider yourself warned!
