Hello,
Thanks for your efforts with Cabal, it seems to work really well.
Can I suggest a few improvements to the above error message:
1. Provide a flag "--force" that says "OK, the user knows best." (Sometimes I change the .cabal file trivially, and really just want to build the thing.) Indeed, a lot of commands might usefully be "--force"d.
Hmm, I'd rather not add a --force to anything. Where else would you want --force? Ideally we would just do whichever bits of re-configuring that are necessary. With a dependency framework this should be quite possible as we could treat each field in the .cabal file as a separate bit of info with it's own timestamp etc.
2. It is a bit unsound to say "please re-configure". You may also need to "clean", if in fact the .cabal file has changed significantly.
Really? Under what circumstances would that be necessary?
So, to say that another way, the message provides both insufficient and unnecessary advice, but I think it can be improved.
How about just re-running configure if we think it's necessary, and using the previous configuration flags? Duncan
