vty-5.11.2: A simple terminal UI library

Safe HaskellNone



Terminfo based terminal handling.

The color handling assumes tektronix like. No HP support provided. If the terminal is not one I have easy access to then color support is entirely based of the docs. Probably with some assumptions mixed in.

Uses terminfo for all control codes. While this should provide the most compatible terminal - terminfo does not support some features that would increase efficiency and improve compatibility: - - * determine the character encoding supported by the terminal. Should this be taken from the LANG - environment variable? - - * Provide independent string capabilities for all display attributes. - - todo: Some display attributes like underline and bold have independent string capabilities that - should be used instead of the generic "sgr" string capability.
