if you plan to support/improve this library, can you please:
I intend to further clean up this code, and also some profiling and quichchecking -- at the moment it is fresh from the darcs-unstable branch. However, before doing more than just clean ups, I'd be inclined to see SimonM's code (rumour has it that he has some fast IO module in the works).
1) add psniceq/pscmp to export list (with better names, smtg like eqPS/cmpPS)
Ok.
2) add case-ignoring-versions of these operations (i want to use packed strings to represent filenames, and under Windows filenames are case-insensetive, while under Unix is not)
Hmm. Couldn't you just mapPS toLower ? We don't have case-ignoring versions of any List functions, so it seems strange to have them here.
about details of realization - is not it better to use just memcmp to implement pscmp and also "psniceq a b = (pscmp a b) == EQ" ?
I would think so, yes. I'll have to work out why it has been written the way has been.
imho, such library must be included in GHC itself - sooner or later. using 8-times memory representation for ordinary strings is just disastrous for some projects
Agreed. -- Don
