where to put project pages on haskell wiki?
by Conal Elliott 10 Jan '07

10 Jan '07

Are there any thoughts or even consensus on where to place project/package pages on http://haskell.org/haskellwiki? I don't see any common structure. Haskore & Hoogle have pages right under haskellwiki. Another idea is to put them by Cabal package name under http://haskell.org/haskellwiki/Package. - Conal

RE: Idea to allow people to comment on Haskell docs

| I've had a go at patching Haddock to put a link on the page for each | module. It's controlled by an optional --wiki=URL flag. | | As an example, I used this with the (devel version of the) Gtk2Hs docs: | | http://haskell.org/gtk2hs/docs/devel/ | | For example this page: | | http://haskell.org/gtk2hs/docs/devel/Graphics-Rendering-Cairo-SVG.html It looks great! But I'd never have found the link if you hadn't pointed me at it. Rather than "Wiki" say "User comments". And I think the per-entry [User comment] link is essential. Typically people are going to be looking at a particular thing. For example, here http://haskell.org/gtk2hs/docs/devel/Graphics-Rendering-Cairo-SVG.html#v %3AsvgRenderFromString is where I'd look for the link for svgRenderFromString. Does MediaWiki support anchors in the middle of a page? That's essential here -- we want one Wiki page for one Haddock page. On a closely related matter, Benjamin Pierce told me how often he wished that there was a link from the Haddock documentation to the source code for a function. Especially for Prelude functions, he's dead right. So another really useful Haddock enhancement would be the ability to add links to the source code from the Haddock docs --- again on a per-function basis. Do you feel like adding that too? Where should the code live? I'd suggest snap-shoting it at the moment that the Haddock docs are generated, and putting the files with the Haddock docs. Simon

getting cabal to pass more info to haddock
by Conal Elliott 09 Jan '07

09 Jan '07

I want Cabal to pass the source-module and source-entity flags to haddock. I can probably figure out how to add these flags into the Cabal source (following the example of --hoogle), but I wonder if there's a better way. Any suggestions? If source mod, is there a process for me to follow? To whom would I send the patch? Thanks, - Conal

Is there a way to tell cabal to pick a particular .cabal file when there are several in the current directory? -- Ashley Yakeley

Hackage interface
by Ross Paterson 06 Jan '07

06 Jan '07

I've put up (temporarily) a crude first cut at an interface to the Hackage package database at http://ross-paterson.dyndns.org/~ross/hackage/ Obviously it could be a lot prettier. Also package upload uses the same logins as the GHC Wiki, but we'd want to change that.

package pages in Hackage
by Ross Paterson 05 Jan '07

05 Jan '07

Björn Bringert has a number of ideas for things that could be added to package web pages offered by a Hackage interface, some of which are implemented in his proof-of-concept hask-home: http://www.cs.chalmers.se/~bringert/darcs/hask-home/doc/ I'd like to see things like who uploaded the package and when, and the results of automatic builds of the package. Just knowing whether a package compiles with recent compiler releases would be an excellent bitrot filter. Presumably others will have more ideas, and we'd like them to be able to add things without having to modify the CGI program. So perhaps we could have a directory <package-id>.parts containing fragments of the package page (in either HTML or Björn's HMarkup) which the CGI program stitches together, with some means of specifying the order. Some of these parts could be generated asynchronously, e.g. by build daemons.

ANN: monadLib 3.0.0
by Iavor Diatchki 04 Jan '07

04 Jan '07

Hello, I have placed a new version of 'monadLib' on its web-page: http://www.csee.ogi.edu/~diatchki/monadLib Some of the changes compared to the previous version: * The whole library is in a single module MonadLib.hs (~500 lines) * Simpler and more symmetric API * Removed the (generic) monadic combinators * Removed the search transformer (may add another version of it at some point) * Rewrote some transformers in the "traditional" way (e.g., exceptions and output) * There is an optional module that defines base monads corresponding to each transformer. Comments are very welcome. -Iavor

authentication for hackage uploads
by Ross Paterson 04 Jan '07

04 Jan '07

We need some security on uploads to hackage, because Cabal packages can run arbitrary code during the build process (and when in use). I think that Apache authentication (as used in Trac, for example) would be sufficient, but that the initial registration of submitters needs to be done manually by a small group of people. We need to know who we're dealing with, and we need at least an email address to contact them. Personally, I'd prefer that user names were real names in camel case, but maybe I'm too old-fashioned. Any views?

mtl vs monads
by Conal Elliott 03 Jan '07

Are the mtl and monads (monadLib) packages both in active use? Is one being phased out? - Conal
