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. | |
1992 | 25 * - recorded characters: for the "q" command. |
7 | 26 * |
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! | |
34 * | |
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(). | |

60 * typebuf.tb_buf[] contains all characters that are not consumed yet. | |
61 * typebuf.tb_buf[typebuf.tb_off] is the first valid character. | |
62 * typebuf.tb_buf[typebuf.tb_off + typebuf.tb_len - 1] is the last valid char. | |
63 * typebuf.tb_buf[typebuf.tb_off + typebuf.tb_len] must be NUL. | |
64 * The head of the buffer may contain the result of mappings, abbreviations | |
65 * and @a commands. The length of this part is typebuf.tb_maplen. | |
66 * typebuf.tb_silent is the part where <silent> applies. | |
67 * After the head are characters that come from the terminal. | |
68 * typebuf.tb_no_abbr_cnt is the number of characters in typebuf.tb_buf that | |
69 * should not be considered for abbreviations. | |
70 * Some parts of typebuf.tb_buf may not be mapped. These parts are remembered | |
71 * in typebuf.tb_noremap[], which is the same length as typebuf.tb_buf and | |
72 * contains RM_NONE for the characters that are not to be remapped. | |
73 * typebuf.tb_noremap[typebuf.tb_off] is the first valid flag. | |
74 * (typebuf has been put in globals.h, because check_termcode() needs it). | |
