Nerpa plugin, NRP-2006-01-18

Sorry, package was wrong - it was from previous internal build. If you have
MassFixTest.cs file in source\Netix.Nerpa.Test\ subfolder, please redownload
the package.

Hi Ilya,


I was trying to modify your plugin to enable the generic checking of
FxCop rules (but stranded with lack of time and documentation of FxCop),
do you think it would it be possible (not asking u to do it, just an
opinion) to adapt your plugin to enable such a feature, and allow people
to add their own resolving classes/methods (automatically add COMVisible
attribute, etc etc), for each FxCop rule?

Combined with Resharper being able to batch-resolve each possible
warning in a complete project, that would make a nice tool don't you think?

Hello Wiebe,

I afraid it's not possible to use FxCop rule libraries. First, they operate
on compiled assembly and thus does not have to deal with incomplete code.
Second, they use completely different API which would be hard yet even possible
to adopt for Resharper. Third, they don't contain code for correcting problems,
which is the most important thing in Resharper context. And the last - there
are a lot of false positives which requires mechanism for excluding warnings.

I think we'd better wait until JetBrains setup workplace for plugins and
then reimplement most important rules along with quickfixes. For example,
I don't think that assembly-level attributes checks are important rules.
If they even were implemented, you'd almost never see it - how often do you
open AssemblyInfo.cs file? If you browse FxCop rules, you will see that most
of them are not suitable for Resharper.

On exclusions: I realise, that tool like Nerpa should have some method for
ignoring suggestions. I'm working on it.

Sincerely,
Ilya Ryzhenkov

I've thought of that by saving the FXCop output to a temporary file, and
parsing that in the background. I think it includes source code
information from the PDB file as well.

That would mean the rules would only apply if the code has been compiled
at least once and remained unchanged afterwards.

True, but if you use the standard FXCop project files to output the
results, you can use FXCop to ignore/include rules.

But anyway, thanks for your input, there is indeed a need to write a
quickfix for each FXCop rule, but most of them shouldn't be that
difficult with the R# API.

Like you said, I thought it will be the most difficult adapting the
FXCop API to the R# API.

The assembly attribute was only an example (though I do access the
AssemblyInfo.cs a lot, version changes, permissions etc ;), I do think
FXCop has loads of other useful rules, like unused internal
classes/methods, spell-checking methods/variables.

Thanks for your input (and useful tool, great example for R# API as well)
