2025-09-06vt: add support for smput/rmput escape codesCalixte Pernot1-0/+58
Support "\e[?1049h" and "\e[?1049l" escape codes. This patch allows programs to enter and leave alternate screens. This feature is widely available in graphical terminal emulators and mostly used by fullscreen terminal-based user interfaces such as text editors. Most editors such as vim and nano assume this escape code in not supported and will not try to print the escape sequence if TERM=linux. To try out this patch, run `TERM=xterm-256color vim` inside a VT.

2025-07-22vt: defkeymap: Map keycodes above 127 to K_HOLEMyrrh Periwinkle1-0/+112
The maximum number of keycodes got bumped to 256 a very long time ago, but the default keymaps were never adjusted to match. This is causing the kernel to interpret keycodes above 127 as U+0000 if the shipped generated keymap is used. Fix this by mapping all keycodes above 127 to K_HOLE so the kernel ignores them. The contents of this patche were generated by rerunning `loadkeys --mktable --unicode` and only including the changes to map keycodes above 127 to K_HOLE.

2025-05-21vt: add VT_GETCONSIZECSRPOS to retrieve console size and cursor positionNicolas Pitre1-0/+16
The console dimension and cursor position are available through the /dev/vcsa interface already. However the /dev/vcsa header format uses single-byte fields therefore those values are clamped to 255. As surprizing as this may seem, some people do use 240-column 67-row screens (a 1920x1080 monitor with 8x16 pixel fonts) which is getting close to the limit. Monitors with higher resolution are not uncommon these days (3840x2160 producing a 480x135 character display) and it is just a matter of time before someone with, say, a braille display using the Linux VT console and BRLTTY on such a screen reports a bug about missing and oddly misaligned screen content. Let's add VT_GETCONSIZECSRPOS for the retrieval of console size and cursor position without byte-sized limitations. The actual console size limit as encoded in vt.c is 32767x32767 so using a short here is appropriate. Then this can be used to get the cursor position when /dev/vcsa reports 255. The screen dimension may already be obtained using TIOCGWINSZ and adding the same information to VT_GETCONSIZECSRPOS might be redundant. However applications that care about cursor position also care about display size and having 2 separate system calls to obtain them separately is wasteful. Also, the cursor position can be queried by writing "\e[6n" to a tty and reading back the result but that may be done only by the actual application using that tty and not a sideline observer.

2025-04-26vt: properly support zero-width Unicode code pointsNicolas Pitre1-2/+68
Zero-width Unicode code points are causing misalignment in vertically aligned content, disrupting the visual layout. Let's handle zero-width code points more intelligently. Double-width code points are stored in the screen grid followed by a white space code point to create the expected screen layout. When a double-width code point is followed by a zero-width code point in the console incoming bytestream (e.g., an emoji with a presentation selector) then we may replace the white space padding by that zero-width code point instead of dropping it. This maximize screen content information while preserving proper layout. If a zero-width code point is preceded by a single-width code point then the above trick is not possible and such zero-width code point must be dropped. VS16 (Variation Selector 16, U+FE0F) is special as it typically doubles the width of the preceding single-width code point. We handle that case by giving VS16 a width of 1 instead of 0 when that happens.
