Description Mikayla Hutchinson [MSFT] 2015-08-14 17:56:09 UTC
This is likely a nonzero exit code or message on stderr, but it's confusing for users.

@sebastien: is this stderr message from mtouch itself or a native lib that mtouch uses? http://screencast.com/t/QZ6ykXxhi (2KB)


Jeffrey Stedfast [11:54 AM]
can mtouch remove that text?

Sebastien Pouliot [11:54 AM] 
that comes from Apple libs (edited)

Jeffrey Stedfast [11:54 AM] 
the problem is that the text shows up red (which insinuates "ERROR!") but it's actually a success message

Sebastien Pouliot [11:54 AM] 
and they vary by each version/release of Xcode

Jeffrey Stedfast [11:55 AM] 
XS color codes all stderr text in red

Jeffrey Stedfast [11:55 AM]
yea, I was afraid of that

Sebastien Pouliot [11:55 AM] 
afaik it’s red because XS display it as such (everything from stderr) (edited)

Jeffrey Stedfast [11:55 AM] 
right

Jeffrey Stedfast [11:55 AM]
but if it changes every release of xcode, we won't be able to effectively filter it out
Comment 2 Jeffrey Stedfast 2015-08-18 12:02:01 UTC
does mtouch itself write anything to stderr?

Jeffrey Stedfast [11:57 AM]
maybe we can just drop all stderr text

Sebastien Pouliot [11:57 AM] 
yeah, it’s an unbound list and any pattern risk hiding something important :neutral_face:

Sebastien Pouliot [11:58 AM]
I don’t think mtouch uses stderr, at least not for messages intended for users
Comment 3 Mikayla Hutchinson [MSFT] 2015-08-20 16:37:52 UTC
Could we maybe use some very limited patterns, e.g. allow for the line number to change and nothing else?

Perhaps printing a final "Success" message at the end *after* all the mtouch output would help?
Comment 4 Jeffrey Stedfast 2015-09-01 12:32:41 UTC
I wrote custom IConsole and custom TextWriter wrappers to try and filter this out. It's the best we can do.
