OSC 702 Report Version
Ask rxvt-unicode for its name and version.
OSC 702 ; ? ST
- ECMA-48
- §8.3.89 OSC – Operating System Command, p. 51
- Specification
- urxvt(7), XTerm Operating System Commands
OSC 702 ; ? ST asks rxvt-unicode who it is. It answers OSC 702 ; rxvt-unicode ; name ; major ; minor, ended the way the request was, with name the resource name it runs under, such as urxvt. The manual’s example is version 7.4 (urxvt(7)). Only ? does anything. rxvt-unicode’s source takes the major and minor numbers as single characters of its version string, so 9.31 reports a minor version of 3. XTVERSION is xterm’s way to ask the same.
A default xterm has no OSC 702 and ignores it (the OSC numbers it knows). The cases follow xterm.
libghostty-vt does not recognize OSC 702 either: its OSC parser in osc.zig has no state for the number, so the string is dropped, and the cases pass.
