MSBuild and IgnoreStandardErrorWarningFormat

Question

I'm trying to write a MSBuild project that will generate html documentation using doxygen. I couldn't find anything about that on the net except for one example, which seems incomplete; it doesn't parse doxygen warnings.

I found that MSBuild's Exec task has parameters like IgnoreStandardErrorWarningFormat and CustomWarningRegularExpression. What is the "Standard Error/Warning Format" and what kind of REs are allowed in these properties?

Edit: ah, "Inside the Microsoft Build Engine" wrongly describes it as property in .NET 3.5, where it is actually from 4. No use for me...

Answer 1

I can't find docs on it right now, but I think the standard error format is something like

.*(\d+(,\d+(,\d+,\d+)?)?)?: error .*:.*
.*(\d+(,\d+(,\d+,\d+)?)?)?: warning .*:.*

examples:

c:\somefile.txt(10,20,10,30): error CMD1234: blarg
c:\somefile.txt(10,20): error CMD1234: yadda yadda
c:\somefile.txt: warning ARG5678: blah blah
