my usual warning: not anyone has 24h internet connection. i've switched to adsl just 1 month ago. printing url for *installed* documentation may be better (and it will reflect actual flags supported by *this* ghc version) -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com

Indeed, the installed version would be much better

it would indeed be kind of nice if ghc (perhaps via ghc-pkg??) knew if and where its documentation was installed. but i consult the locally installed users' guide quite as often on other topics than flags, and usually have several ghcs installed, and some ghc installations appear to come without, or with partial html docs (for whatever reason), and i have at least one editor-script (*) that needs to figure out where the html docs are for the ghc in $PATH (that editor-script did indeed start out as a convenient way to get at the GHC and library docs while editing Haskell code in VIM, and currently tries to guess the docdir from the libdir, which won't work in general). so, how about (in analogy to --print-libdir): ghc --print-docdir c:/ghc/ghc-6.6/doc/html or whereever the local docs are rooted, if there are local docs, and ghc --print-docdir http://www.haskell.org/ghc/docs/6.6/html/ if there are no local docs installed (note the paths to version-specific docs). currently, adding "/users_guide/flag-reference.html" to the result would lead to the appropriate section for flags, which could be done by a simple wrapper, and i'd find --print-docdir more generally useful. claus (*) Doc.vim (finding haddocks, auto-completing names, adding imports; for VIM) http://www.cs.kent.ac.uk/people/staff/cr3/toolbox/haskell/Vim/Doc.vim

A full listing of the available flags would be useful too for a hypothetic bash complete mode. I think that's how the bash completion package for darcs does it. And you know, with those three or four words compound flags, with their number rising to .. nearly a hundred?, this would be a very desirable thing to have, much more so than the darcs one. On the other hand, both --full-flag-help and the bash completion package mode seem like a very trivial hacking task. Any GHC hackers around? /me hides under a pile of work and other diversions Cheers pepe On 13/03/2007, at 20:33, Lennart Augustsson wrote:

Sorry, but I'm not always connected to the Internet. I'd like to be able to get flag help easily anyway.
