Re: [wxhaskell-devel] No more Eiffel

[Eric K. <eri...@gm...>]

Thanks, Dave,

Unfortunately, I'm going to have to switch back to hunker-down mode for wxHaskell.  But here's what I can add:

Not really, but I can guess from the patch titles

Minimal Dependencies
--------------------
Some semantic dependencies may be missing:

  * wxEventType is an extern type in wxWidgets 2.9.2
  * Rudimentary replacement for wx-config.
  * Don't forget parent dir in wx-config prefix search.
  * Fix oversight: include the wxWidgets libs in wx-config output.
  * use Haskell WxConfig library instead of wx-config on Windows

Minimal wxWidgets 2.9
---------------------
  * Only install the wx-config executable on Windows
  * WIP: do a better job grabbing extra lib arguments
  * Disable webkit and power events that were causing compile errors.
  * wxDrag+varia,
  * wxcore: remove wxPostScriptDC::{Set,Get}Resolution
  * PolygonFillModeFix
  * wxcore: Convert wxString to wchar_t* not char*
  * WIP: Remove references to wxPendingEvents
  * WIP: Remove more missing stuff

Minimal GHC 7.2
---------------
  * Fix build on GHC 7.2.
  * wx: FlexibleInstances for GHC 7.2

Minimal No More Eiffel
----------------------
  * wxcore: No more Eiffel (can probably stand alone)
  * wxcore: Remove elj prefix from cpp files.
  * wxcore: No more Eiffel followup

Probably not needed
-------------------
  * Fix inconsistent newline terminator
  * wxdirect: Strip away ability to deal with Eiffel files.
  * wxdirect: Modernise exception handling.
  * wxdirect: Bump to 0.14
  * Update Graphics.UI.WXCore.WxcDefs haddock to reflect manual maintenance.
  * Trailing newlines on EOF.
  * Modernise examples not to require haskell98 package

I'd like to push them to a fork but I need to sort out some technical issues with Alex first.

Meanwhile, know that you can cherry pick from emailed patches with darcs apply -i

Before the patch, wxdirect parses the Eiffel files and spits out equivalent Haskell code.  The patch simply adds the results of this process to the repo and drops the bit of Setup.hs that does this parsing.

Careful: it may actually be worthwhile to retain the *functionality* in wxdirect  that does this parsing.  Not sure, but maybe this would be helpful in cases where people for some reason want to install an old wxcore, without us having to ask them to downgrade wxdirect.

> 4. How "WIP" do you mean by "WIP"? :)

I think it means two things

(A) I don't know if this is a good idea, but it's otherwise complete
(B) This works for me but I'm pretty sure it won't work for you

In the case of the "do a better job" patch, updating this may actually be quite easy.  You just need to ignore the basename stuff on Windows, and append a "-2.8" (or whatever as the case may be in case we're not using wxWidgets 2.8)

The other patches probably belong in the B category.  De-WIPping them probably just consists in thinking about whether or not this would actually be a good idea in practice and darcs amend --edit'ing the name.  Unfortunately, having the two patches in a repo at a same time would be conflict, so one would have to uvpull  the wippy versions first before pulling the rename.
