| 11 * Terminal window support, see ":help :terminal". | |
| 12 * | |
| 13 * There are three parts: | |
| 14 * 1. Generic code for all systems. | |
| 15 * Uses libvterm for the terminal emulator. | |
| 16 * 2. The MS-Windows implementation. | |
| 17 * Uses winpty. | |
| 18 * 3. The Unix-like implementation. | |
| 19 * Uses pseudo-tty's (pty's). | |
| 20 * | |
| 21 * For each terminal one VTerm is constructed. This uses libvterm. A copy of | |
| 22 * this library is in the libvterm directory. | |
| 23 * | |
| 24 * When a terminal window is opened, a job is started that will be connected to | |
| 25 * the terminal emulator. | |
| 26 * | |
| 27 * If the terminal window has keyboard focus, typed keys are converted to the | |
| 28 * terminal encoding and writing to the job over a channel. | |
| 29 * | |
| 30 * If the job produces output, it is written to the terminal emulator. The | |
| 31 * terminal emulator invokes callbacks when its screen content changes. The | |
| 32 * line range is stored in tl_dirty_row_start and tl_dirty_row_end. Once in a | |
| 33 * while, if the terminal window is visible, the screen contents is drawn. | |
| 34 * | |
| 35 * When the job ends the text is put in a buffer. Redrawing then happens from | |
| 36 * that buffer, attributes come from the scrollback buffer tl_scrollback. | |
| 37 * When the buffer is changed it is turned into a normal buffer, the attributes | |
| 38 * in tl_scrollback are no longer used. | |
| 39 * | |
| 40 * TODO: | |
| 41 * - in GUI vertical split causes problems. Cursor is flickering. (Hirohito | |
| 42 * Higashi, 2017 Sep 19) | |
| 43 * - Shift-Tab does not work. | |

59 * - Redrawing is slow with Athena and Motif. |
| 12502 | 60 * - For the GUI fill termios with default values, perhaps like pangoterm: |
| 61 * http://bazaar.launchpad.net/~leonerd/pangoterm/trunk/view/head:/main.c#L134 | |
| 62 * - if the job in the terminal does not support the mouse, we can use the | |
| 63 * mouse in the Terminal window for copy/paste. | |
| 64 * - when 'encoding' is not utf-8, or the job is using another encoding, setup | |
| 65 * conversions. | |
| 66 * - In the GUI use a terminal emulator for :!cmd. Make the height the same as | |
| 67 * the window and position it higher up when it gets filled, so it looks like | |
| 68 * the text scrolls up. | |
| 69 * - Copy text in the vterm to the Vim buffer once in a while, so that | |
| 70 * completion works. | |
| 71 * - add an optional limit for the scrollback size. When reaching it remove | |
| 72 * 10% at the start. | |
