[Scons-users] Eclipse-friendly compile error output

[Geza Lore]

Hi,

You can filter the compiler output by doing something along these lines (I used this for colouring by piping through sed ...):



sedSP = subprocess.Popen([r'sed',
                          r'-e', env.subst(r's/.*\(^\|[^=]\b\)Err.*/${RED}${BOLD}&${PLAIN}/i', raw=1),
                          r'-e', env.subst(r's/.*\bWarn.*/${YELLOW}${BOLD}&${PLAIN}/i', raw=1)],
                          stdin=subprocess.PIPE)
sys.stdout = sedSP.stdin
sys.stderr = sedSP.stdin

# Make sure spawned command output is fed thorugh the SCons output, so it's piped to sed
def SpawnWrapper(pspawn):
   def newSpawn(sh, escape, cmd, args, env):
        return pspawn(sh, escape, cmd, args, env, sys.stdout, sys.stderr)
    return newSpawn

env['SPAWN'] = SpawnWrapper(env['PSPAWN'])




If you want to keep stdout and stderr separate, then you can fork off 2 processes to filter them separately.

Bests,
Geza

from the compiler,

No, SCons does not handle or filter the compiler output (stdout, stderr).  It just runs the commands.
