This plugin is still under active development.
==============================================
It is not even remotely ready yet. Lots of things are unimplemented.
=====================================================================
It will probably eat your data.
===============================
Seriously. If you use it and complain about it eating your data I am going to make fun of you on Twitter.
======================
Threesome is a Vim plugin for resolving conflicts during three-way merges.
It's designed to be used as a merge tool for version control systems like
Mercurial and Git.
Requirements
============
Vim 7.3+ compiled with Python 2.5+ support.
Yes, that's some (relatively) new stuff. No, I'm not going to support anything less
than that.
Threesome is a merge tool which means you'll be working with it on your development
machine, not over SSH on your servers.
If you can't be bothered to run up-to-date versions of your tools on your main
development machine, I can't be bothered to clutter the codebase to support you.
Feels bad, man.
Installation
============
Use Pathogen to install the plugin.
Build the docs:
:call pathogen#helptags()
Add it as a merge tool for your VCS of choice:
**Mercurial:** add the following lines to `~/.hgrc`:
[merge-tools]
threesome.executable = mvim
threesome.args = -f $base $local $other $output -c 'ThreesomeInit'
threesome.premerge = keep
threesome.priority = 1
**Git:** add the following lines to `~/.gitconfig`:
[merge]
tool = threesome
[mergetool "threesome"]
cmd = "mvim -f $BASE $LOCAL $REMOTE $MERGED -c 'ThreesomeInit'"
trustExitCode = true
**Note:** replace `mvim` with `gvim` if you're on Linux, or just plain `vim` if you
prefer to keep the editor in the console.
More Information
================
Read the docs: `:help threesome`
Key Bindings
============
Threesome makes use of `<localleader>` for all of its key bindings to avoid
clashing with global mappings. If you've never used `<localleader>` now
would be a good time to read the help and configure a key for it.
All keybindings that are used across all modes. The behavior of some of them
changes depending on the current mode, but the effects should be fairly
intuitive.
Mode Selection
--------------
All keybindings begin with `<localleader>`.
* `g` - Grid - Switch to grid view.
* `l` - Loupe - Switch to loupe view.
* `c` - Compare - Switch to compare view.
* `p` - Path - Switch to path view.
File Selection
--------------
All keybindings begin with `<localleader>`.
* `o` - Original - Select the original file.
* `1` - One - Select file one.
* `2` - Two - Select file two.
* `r` - Result - Select the result file.
Other
-----
All keybindings begin with `<localleader>`.
* `d` - Diff - Cycle through various diff combinations.
* `u` - Use Hunk - Place a hunk from file one or two into the result file.
* `s` - Scroll - Toggle scroll locking on and off.
* `<space>` - Layout - Cycle through various layouts of the current view.
* `n` - Next - Move to the next unresolved conflict.
* `N` - Previous - Move to the previous unresolved conflict.
* `q` - Quit - Save the result file and exit Vim. Indicates to the VCS that the merge was successful and it should use the current contents of the result file as the result.
* `CC` - Cancel - Exits Vim with an error code (like :cq). Indicates to the VCS that the merge was NOT successful.
Modes
=====
This section describes each mode in detail.
Grid
----
The grid view is used to get an overview of all files at once to get a birds'
eye view of the merge.
### Grid Layouts
Layout 1 Layout 2
+-------------------+ +--------------------------+
| Original | | One | Result | Two |
| | | | | |
+-------------------+ | | | |
| One | Two | | | | |
| | | | | | |
+-------------------+ | | | |
| Result | | | | |

+-------------------+ +--------------------------+
### Grid-Specific Key Bindings
All keybindings begin with `<localleader>`.
* `o` - Original - Focus the original file (only in layout 1).
* `1` - One - Focus file one.
* `2` - Two - Focus file two.
* `r` - Result - Focus the result file.
* `d` - Diff - Cycle through various diff combinations.
* `u1` - Use Hunk 1 - Place a hunk from file one into the result file.
* `u2` - Use Hunk 2 - Place a hunk from file two into the result file.
### Grid Diffs
1. No diff.
2. Diff the original and file one.
3. Diff the original and file two.
4. Diff file one and the result.
5. Diff file two and the result.
6. Diff the original and the result.
Loupe
-----
The loupe view is used to focus on and examine a single file in detail.

2. Diff both windows.
Path
----
The path view is used to view the flow of changed through one "path" or
"branch" of the merge.
### Path Layouts
