Thanks for replying. I will be using cabal init --overwrite until the new feature is complete :D

I have been working on a haskell scotty project recently. I have just added configuration support for the project, which added an extra dependency of Control.Lens. My question is: is there a way update .cabal file automatically, just like cabal init but without recreate .cabal file? No. I've been planning to work on that, but haven't had the time yet. Thanks for the reminder.

Do you have a copy of the error message we can look at? It's hard to say anything without that. If the output is long, it might be better to put it up on http://lpaste.net/ instead of including it right in the email. On Wed, Jul 30, 2014 at 12:54 AM, ye yan wrote:

git add -p works very good in this case, thank you for your advise. Just wondering how does cabal solve dependencies?

I updated my cabal file. ghci works find with my development box. but when I checkout with other computer I got a dependency error. It seems cabal failed to detect the correct library version I am using in ghci. Or just because for parsec library I have multiple versions installed?
