Yeesh.MixShell
(Yeesh v0.8.3)
View Source
Custom Mix.Shell implementation for Yeesh Mix task execution.
Identical to Mix.Shell.IO except that error/1 writes through
IO.puts/1 (which routes through the process group leader) instead
of writing to :standard_error directly. This ensures error output
from Mix tasks is captured by Yeesh.IOServer when the task's
group leader has been replaced.
For processes with a normal group leader, the behaviour is
effectively identical to Mix.Shell.IO -- output goes to stdout
through the default group leader.
This module is only compiled when Mix.Shell is available (i.e.
in dev/test environments, not in releases).
