Brad Smith / ANSITermMenuSystem

Inspired by Simon Ford's "Terminal" library, this is a clean-room reimplementation that supports a larger set of the ANSI escape sequences and includes a few handy drawing routines. Useful for making console UIs for your projects. The box-drawing stuff requires your terminal to be set to codepage 850.

dansummers 0:863811463610 36 *
dansummers 0:863811463610 37 * ANSITerm encapsulates a large portion of the ANSI escape sequence set,
dansummers 0:863811463610 38 * so that a user unfamiliar with the escape sequences can manipulate the
dansummers 0:863811463610 39 * terminal. It also provides a tidy point of abstraction, should it be
dansummers 0:863811463610 40 * necessary to support multiple different escape sets in the future.
dansummers 0:863811463610 41 *
dansummers 0:863811463610 42 * ANSITerm assumes that the terminal being manipulated implements the
dansummers 0:863811463610 43 * ANSI-standard escapes. The terminal is divided into cells, each one
dansummers 0:863811463610 44 * the size of a character (a typical "default" terminal will have 25 rows of
dansummers 0:863811463610 45 * cells, each with 80 character cells in it, but this will change if the
dansummers 0:863811463610 46 * terminal is resized.)
dansummers 0:863811463610 47 *
dansummers 0:863811463610 48 * The box-drawing functions currently assume that the terminal is using
dansummers 0:863811463610 49 * CodePage 850 to interpret received characters. It is untested under
dansummers 0:863811463610 50 * UNIX and MacOS (fixing this is on the TODO list).
dansummers 0:863811463610 51 *
dansummers 0:863811463610 52 * Example:
dansummers 0:863811463610 53 * @code
dansummers 0:863811463610 54 * terminal.clear_screen();
dansummers 0:863811463610 55 * terminal.hide_cursor();
dansummers 0:863811463610 56 * terminal.set_display_style(ANSITerm::SGR_NONE);
dansummers 0:863811463610 57 * terminal.set_text_colour(ANSITerm::SGR_RED);
dansummers 0:863811463610 58 * terminal.draw_box(3,3,19,5,ANSITerm::simple,false);
dansummers 0:863811463610 59 * terminal.set_text_colour(ANSITerm::SGR_WHITE);
dansummers 0:863811463610 60 * terminal.set_display_style(ANSITerm::SGR_BOLD);
dansummers 0:863811463610 61 * terminal.set_cursor_position(5,4);
