From 899c2af576124df2918fd2ae976434df0ebbae5b Mon Sep 17 00:00:00 2001 From: _ov4 Date: Wed, 21 Oct 2026 14:06:54 +0000 Subject: feat(driver): color diagnostics like gcc with -fdiagnostics-color Add -fdiagnostics-color[=auto|always|never] and -fno-diagnostics-color. The default auto mode colors only a terminal stderr (TERM set and not dumb on Unix; a console that accepts VT sequences on Windows), so test harnesses, the desktop bundle and other pipes stay plain. Every diagnostic label now comes from cps::diagnosticPrefix, which emits gcc's default GCC_COLORS bytes: bold locus, bold red error/fatal error, bold magenta warning, bold cyan note. compilation terminated., runtime messages of the compiled program and lld output are unchanged.
