Basically, if I understand well, it's a GUI over `git add -p`. Instead of the CLI short diff, you get a `meld` instance that computes the diff between two (virtual) directories, one with the modified files of your git, one with the current index. And like `git -p`, you select what you want to add to the index.
That seems great to have a global vision of modifications, and to be able to navigate between the differents files to remember exactly what belongs to the commit!
I had such a tool in mind since I discovered `git add -p`, thanks for working on it!
Using the tool I'm finding I'm quite often clicking the right arrow to add a hunk to the index, then just editing the right hand side to delete a few lines or tweak what was edited somehow. This is a very "natural" way to stage just what you want.
Also once it supports git reset -p like functionality and also editing the working tree (see the README), I guess that visual editing workflow will get more powerful.
Eclipse's egit plugin provides visual partial staging.
This tool sounds great, but in case you didn't know, 'git add -p' supports '/' to search for a matching hunk.
In some cases meld is easier / quicker to use than git add -p or the staging feature in tools like git gui. That's because meld allows you, for example, to:
see more context
see intra-line diffs
edit by hand and see 'live' diff updates (updated after every keypress)
navigate to a change without saying 'n' to every change you want to skip
Q. Why not just use <favourite staging tool>?
A. Different tools have different pros and cons. You should use what works best for you for a given task! However, I do find tools like meld have some advantages -- see the list at the top of this README for some of them. Try it and see what works for you.
