// Package tcell provides a lower-level, portable API for building
|
||
|
|
// programs that interact with terminals or consoles. It works with
|
||
|
|
// both common (and many uncommon!) terminals or terminal emulators,
|
||
|
|
// and Windows console implementations.
|
||
|
|
//
|
||
|
|
// It provides support for up to 256 colors, text attributes, and box drawing
|
||
|
|
// elements. A database of terminals built from a real terminfo database
|
||
|
|
// is provided, along with code to generate new database entries.
|
||
|
|
//
|
||
|
|
// Tcell offers very rich support for mice, dependent upon the terminal
|
||
|
|
// of course. (Windows, XTerm, and iTerm 2 are known to work very well.)
|
||
|
|
//
|
||
|
|
// If the environment is not Unicode by default, such as an ISO8859 based
|
||
|
|
// locale or GB18030, Tcell can convert input and output, so that your
|
||
|
|
// terminal can operate in whatever locale is most convenient, while the
|
||
|
|
// application program can just assume "everything is UTF-8". Reasonable
|
||
|
|
// defaults are used for updating characters to something suitable for
|
||
|
|
// display. Unicode box drawing characters will be converted to use the
|
||
|
|
// alternate character set of your terminal, if native conversions are
|
||
|
|
// not available. If no ACS is available, then some ASCII fallbacks will
|
||
|
|
// be used.
|
||
|
|
//
|
||
|
|
// Note that support for non-UTF-8 locales (other than C) must be enabled
|
||
|
|
// by the application using RegisterEncoding() -- we don't have them all
|
||
|
|
// enabled by default to avoid bloating the application unnecessarily.
|
||
|
|
// (These days UTF-8 is good enough for almost everyone, and nobody should
|
||
|
|
// be using legacy locales anymore.) Also, actual glyphs for various code
|
||
|
|
// point will only be displayed if your terminal or emulator (or the font
|
||
|
|
// the emulator is using) supports them.
|
||
|
|
//
|
||
|
|
// A rich set of key codes is supported, with support for up to 65 function
|
||
|
|
// keys, and various other special keys.
