Please see http://wiki.g2.bx.psu.edu/Admin/Tools/Tool%20Config%20Syntax .
There is a section for "<stdio>, <regex>, and <exit_code> tag sets". The documentation
applies to the latest galaxy-dist, though most of what's mentioned (aside from updating
stdout and stderr with warning messages) is supported in galaxy-central.

(You can also use the fairly ugly URL http://wiki.g2.bx.psu.edu/Admin/Tools/Tool%20Config%20Syntax#A.3Cstdio.3E.2C_.3Cregex.3E.2C_and_.3Cexit_code.3E_tag_sets ).

Hi

I'm writing a tools for an executable that writes results to stdout and reports success message to stderr, so it really need the improved error handling. Is there any sample code or documentation available?

Thanks

Hi Brian,

A couple of days ago, smcmanus pushed the following change to the repo:

Tools can now specify their own handling of stderr and stdout regular expressions as well as exit code ranges. 


It looks like the documentation has yet to be written.


Hope this helps,
Nicole

Is it possible the software is writing to standard error? Galaxy doesn't
check status codes, but rather check for stderr and assumes that output
indicates a problem. You can wrap the problematic programs with a little
script to eat up stderr and check that everything is okay:
