WEZTERM_* env variables
$WEZTERM_PANE, $WEZTERM_EXECUTABLEWezTerm sets a family of
WEZTERM_* environment variables in every spawned shell. WEZTERM_PANE contains the numeric pane ID, WEZTERM_EXECUTABLE points at the wezterm binary, and additional variables expose the config directory and unix socket used by the wezterm cli tool.
Applications can detect a WezTerm session by checking for these variables, and the wezterm CLI uses them to target the correct pane when invoked from within the terminal.How this is testedmanual
Manual verification required — no automated probe available.
Manual verification required — no automated probe available.
The same probe runs against headless backends (via Termless) and real terminal apps (via a daemon launched in each terminal). This lets us distinguish parser correctness from rendering correctness.
