(EXPERIMENTAL) Data type to register a CSI, DCS or ESC callback in the parser in the form: ESC I..I F CSI Prefix P..P I..I F DCS Prefix P..P I..I F data_bytes ST
with these rules/restrictions:
- prefix can only be used with CSI and DCS
- only one leading prefix byte is recognized by the parser before any other parameter bytes (P..P)
- intermediate bytes are recognized up to 2
For custom sequences make sure to read ECMA-48 and the resources at vt100.net to not clash with existing sequences or reserved address space. General recommendations:
- use private address space (see ECMA-48)
- use max one intermediate byte (technically not limited by the spec, in practice there are no sequences with more than one intermediate byte, thus parsers might get confused with more intermediates)
- test against other common emulators to check whether they escape/ignore the sequence correctly
Notes: OSC command registration is handled differently (see addOscHandler) APC, PM or SOS is currently not supported.
