register, update, FlagGlobalConfig, FlagConfigbut all of these seem to expect exactly one file, to be stored in a single FilePath? am i missing something,or was this a wild goose chase?-)Just turn off self-globbing for ghc-pkg. Anyone using a sensible shell (i.e. bash) will still get globbing anyway. I'd be surprised if anyone at all notices.
ok. i don't like excluding users needlessly, but the ghc-pkg commandsdon't seem to be prepared for globbing anyway, so the machinery for enabling selective self-globbing in ghc-pkg is in place, but commented out (to make validate happier) until someone needs it and decides where to provide it.
oddly, i couldn't find a configure.mk variable pointing to the mingw location (there are several programs from there, ar, ld, and distrib/prep-bindist-mingw makes its own guesses), so i used an explicit path in Makefile, which should probably befixed. perhaps you'd like to integrate the glob.hs/CRT_noglob.o combo into ghc proper, as an option for other ghc-compiled
wanting to use '*' on windows? i leave that to you.things appear to work as advertized with ghc-pkg-inplace in cygwin bash and cmd.exe; validate on ghc head, win/xp complains about:
1914(ghci)
ThreadDelay001(normal)
countReaders001(normal)
none of which seem to have anything to do with this patch.
as this patch has platform-specific aspects, you might want
to try on a non-windows platform (provided it does what
you expect on windows;-) before committing (presumably
to both head and stable?).
over to you;-)

------------- updated patch summary
* FIX #1839, #1463, by supporting ghc-pkg bulk queries with substring matching
- #1839 asks for a ghc-pkg dump feature, #1463 for the ability
to query the same fields in several packages at once.
- this patch enables substring matching for packages in 'list',
'describe', and 'field', and for modules in find-module. it
also allows for comma-separated multiple fields in 'field'.
substring matching can optionally ignore cases to avoid the
rather unpredictable capitalisation of packages.
- the patch is not quite as full-featured as the one attached
to #1839, but avoids the additional dependency on regexps.
open ended substrings are indicated by '*' (only the three
forms prefix*, *suffix, *infix* are supported)
- on windows, the use of '*' for package/module name globbing
leads to conflicts with filename globbing: by default, windows
programs are self-globbing, and bash adds another level of
globbing on top of that. it seems impossible to escape '*'
from both levels of globbing, so we disable default globbing
for ghc-pkg and ghc-pkg-inplace. users of bash will still
have filename globbing available, users of cmd won't.
- if it is considered necessary to reenable filename globbing
for cmd users, it should be done selectively, only for
filename parameters. to this end, the patch includes a
glob.hs program which simply echoes its parameters after
filename globbing. see the commented out glob command in
Main.hs for usage or testing.
- this covers both tickets, and permits for the most common
query patterns (finding all packages contributing to the
System. hierarchy, finding all regex or string packages,
listing all package maintainers or haddock directories,
..), which not only i have wanted to have for a long time.
examples (the quotes are needed to escape shell-based
filename globbing and should be omitted in cmd.exe):
ghc-pkg list '*regex*' --ignore-case
ghc-pkg list '*string*' --ignore-case
ghc-pkg list '*gl*' --ignore-case
ghc-pkg find-module 'Data.*'
ghc-pkg find-module '*Monad*'
ghc-pkg field '*' name,maintainer
ghc-pkg field '*' haddock-html
ghc-pkg describe '*'
