Re: [Haskell-cafe] hpc - ignore some expressions

Hi Ozgur, I personally found the paper describing HPC to be quite descriptive. See especially section 3.3 - it seems like it would be possible to hack something up to remove entries containing "error" for example. That being said, I can't find any reference to the program "hpc-makemtix" aside from that paper. Maybe it got folded back into hpc? Did you make any progress with this? http://www.cs.york.ac.uk/plasma/publications/pdf/GillRuncimanHW07.pdf On Mon, Feb 23, 2015 at 9:19 PM, Ozgur Akgun wrote:

I think you are right about it being fragile and becoming a big overhead in maintenance. Maybe one could add some sort of annotation to the sources for which you wish to check coverage and also modify HPC to handle these?

A simple interface where the user provides a list of function names to be ignored would be a good start.

Something like:

hpc markup prog.tix --destdir=report --ignore=fail,error,impossible,undefined

It _could_ also be a good idea to have a way of ignoring literals. Flags like --ignore-num-literals and --ignore-string-literals could treat all such literals as covered or ignored.

Maybe I should put this as a feature request to the hpc maintainers. I am wondering if they maintain an issue tracker or not.

The wiki pages for hpc aren't very helpful...
