2ce6dab2 | 56 | * This implements a complex ECMA-48/ISO 6429/ANSI X3.64 type console, |
34a42e78 KL |
57 | * including a scrollback buffer. |
58 | * | |
59 | * <p> | |
60 | * It currently implements VT100, VT102, VT220, and XTERM with the following | |
61 | * caveats: | |
62 | * | |
63 | * <p> | |
bd8d51fa KL |
64 | * - The vttest scenario for VT220 8-bit controls (11.1.2.3) reports a |
65 | * failure with XTERM. This is due to vttest failing to decode the UTF-8 | |
66 | * stream. | |
67 | * | |
68 | * <p> | |
34a42e78 KL |
69 | * - Smooth scrolling, printing, keyboard locking, keyboard leds, and tests |
70 | * from VT100 are not supported. | |
71 | * | |
72 | * <p> | |
73 | * - User-defined keys (DECUDK), downloadable fonts (DECDLD), and VT100/ANSI | |
74 | * compatibility mode (DECSCL) from VT220 are not supported. (Also, | |
75 | * because DECSCL is not supported, it will fail the last part of the | |
76 | * vttest "Test of VT52 mode" if DeviceType is set to VT220.) | |
77 | * | |
78 | * <p> | |
79 | * - Numeric/application keys from the number pad are not supported because | |
80 | * they are not exposed from the TKeypress API. | |
81 | * | |
82 | * <p> | |
83 | * - VT52 HOLD SCREEN mode is not supported. | |
84 | * | |
85 | * <p> | |
86 | * - In VT52 graphics mode, the 3/, 5/, and 7/ characters (fraction | |
87 | * numerators) are not rendered correctly. | |
88 | * | |
89 | * <p> | |
90 | * - All data meant for the 'printer' (CSI Pc ? i) is discarded. | |

4038 | * permits these ISO-8613-3 SGR sequences to be separated | |
4039 | * by colons rather than semicolons.) | |
4040 | * | |
051e2913 KL |
4041 | * We will support only the following: |
4042 | * | |
4043 | * 1. Indexed color mode (88- or 256-color modes). | |
4044 | * | |
4045 | * 2. Direct RGB. | |
4046 | * | |
4047 | * These cover most of the use cases in the real world. | |
4048 | * | |
4049 | * HOWEVER, note that this is an awful broken "standard", | |
4050 | * with no way to do it "right". See | |
4051 | * http://invisible-island.net/ncurses/ncurses.faq.html#xterm_16MegaColors | |
4052 | * for a detailed discussion of the current state of RGB | |
4053 | * in various terminals, the point of which is that none | |
4054 | * of them really do the same thing despite all appearing | |
4055 | * to be "xterm". | |
4056 | * | |
4057 | * Also see | |
4058 | * https://bugs.kde.org/show_bug.cgi?id=107487#c3 . | |
4059 | * where it is assumed that supporting just the "indexed | |
4060 | * mode" of these sequences (which could align easily | |
4061 | * with existing SGR colors) is assumed to mean full | |
4062 | * support of 24-bit RGB. So it is all or nothing. | |
4063 | * | |
4064 | * Finally, these sequences break the assumptions of | |
4065 | * standard ECMA-48 style parsers as pointed out at | |
4066 | * https://bugs.kde.org/show_bug.cgi?id=107487#c11 . | |
4067 | * Therefore in order to keep a clean display, we cannot | |
4068 | * parse anything else in this sequence. | |
