11 * getchar.c
13 * functions related with getting a character from the user/mapping/redo/...
15 * manipulations with redo buffer and stuff buffer
16 * mappings and abbreviations
19 #include "vim.h"
22 * These buffers are used for storing:
23 * - stuffed characters: A command that is translated into another command.
24 * - redo characters: will redo the last change.
25 * - recorded chracters: for the "q" command.
27 * The bytes are stored like in the typeahead buffer:
28 * - K_SPECIAL introduces a special key (two more bytes follow). A literal
29 * K_SPECIAL is stored as K_SPECIAL KS_SPECIAL KE_FILLER.
30 * - CSI introduces a GUI termcap code (also when gui.in_use is FALSE,
31 * otherwise switching the GUI on would make mappings invalid).
32 * A literal CSI is stored as CSI KS_EXTRA KE_CSI.
33 * These translations are also done on multi-byte characters!
35 * Escaping CSI bytes is done by the system-specific input functions, called
36 * by ui_inchar().
37 * Escaping K_SPECIAL is done by inchar().
38 * Un-escaping is done by vgetc().
