  • Advanced terminal type

    From Deucе@1:103/705 to GitLab issue in main/sbbs on Wednesday, May 20, 2026 12:05:16

    With ansi_terminal.cpp supporting only a historical ANSI-BBS subset, an autodetected advanced terminal type could also be supported.

    This would allow the use of margins, advanced SGR values, better line-ending support, and tracking screen contents.

    A subset of modern features that can be reliably auto-detected would need to be collected, and some likely JS API exposed (presumably via the console object).

    This would allow @mcmlxxix to finally fulfill his hotkey dreams.

    Just a suggestion... I'd start by detecting the position, sending a multi byte character sequence, such as an emoji with skin tone.. then detect the cursor position. This should allow you to determine utf-8 support...

    With that you can assume certain upstream terminal support... You can also query/test for rgb color support.

    1. SyncTERM doesn't support UTF-8, so I'm not understanding the connection between "Advanced Terminal Type" and UNICODE/UTF-8
    2. Synchronet already auto-detects UTF-8 terminals just fine.

    I'm also curious how you can query/test for rgb colour support.

    The DECRQSS probe — set an odd RGB value, then read back what the terminal actually stored:
    Send ESC[48;2;1;2;3m (background to rgb(1,2,3) — no palette entry matches). Send ESC P $ q m ESC \ (DECRQSS request for current SGR).
    Read the reply: ESC P 1 $ r <params> m ESC \.
    If the params echo 48;2;1;2;3 (or 48:2::1:2:3), you have real truecolor. If they come back as 48;5;n or nothing color-ish, the terminal quantized to the 256-color palette. Reset with ESC[0m after.
