Mercurial: No editor appears when merge conflicts are detected

Question

I wonder if anyone here has any experience with mercurial running on Ubuntu? I've been playing with it all morning and love everything I've seen so far.

The one problem I though is when I do a merge and conflicts are detected, it doesn't automatically bring the file up in the command line editor to allow me to resolve the conflicts. It just tells me there's a conflict, then it's up to me to open the editor and resolve it.

But this is strange as the docs show that the editor is automatically launched when there is a merge conflict. I know it's not a problem with the editor (nano) in general as it's works when I do a commit and have to add a comment.

Any ideas?

ps I already tried the mercurial IRC channel, but silence....

Answer 1

You probably need to define your merge tool in ~/.hgrc:

[ui]
merge = vimdiff

Answer 2

What commands are you using, and what does your ~/.hgrc look like? If you're using the fetch extension, it should be opening up a configured merge tool when a conflict is detected.

I detailed my full mercurial config a while back in a blog post where I use kdiff3 as my merge tool.

When doing an "hg fetch" or an "hg merge" (after a conflict is detected) it launches kdiff3 as you'd expect and lets me resolve the merge.
