Do you use `git difftool` to review changes before making a commit? The problem with that is that you get to see the diff of one file at a time. You can't easily stop it after few files and you can't go back to a previous file. `vimtabdiff.py` loads all the files with diffs, one in each vim tab page. You can move around any file and edit the diffs easily.

# Install
|
|
|
|
```bash
|
|
mkdir -p ~/bin
|
|
|
|
# for python version >= 3.10
|
|
curl -o ~/bin/vimtabdiff.py "https://raw.githubusercontent.com/balki/vimtabdiff/master/vimtabdiff.py"
|
|
|
|
# for python version < 3.10
|
|
curl -o ~/bin/vimtabdiff.py "https://raw.githubusercontent.com/balki/vimtabdiff/py38/vimtabdiff.py"
|
|
|
|
chmod +x ~/bin/vimtabdiff.py
|
|
```
|
|
|
|
You may need to add `~/bin` to your PATH variable if not already done. See [here](https://wiki.archlinux.org/title/Environment_variables#Per_user) for help.

## Relevant vim tips
|
|
|
|
* `gt` → Go to next tab
|
|
* `gT` → Go to previous tab
|
|
* `:tabr` → Go to first tab
|
|
* `:drop filenam<Tab>` → Go to the tab with filename
|
|
* `g<Tab>` → Go to last used tab (Works in vim version > 8.2.1401)
|
|
* `:set mouse=a` → Now clicking on a tab works
|
|
* `]c` → Go to next diff hunk
|
|
* `[c` → Go to previous diff hunk
|
|
* `do`, `dp` → Diff obtain, Diff put
|
|
* `zo`, `zc`, `zi` → Fold open, Fold close, toggle all folds

# See Git diffs
|
|
|
|
|
|
## Setup
|
|
```bash
|
|
git config --global difftool.vimtabdiff.cmd 'vimtabdiff.py $LOCAL $REMOTE'
|
|
git config --global alias.dt 'difftool --tool vimtabdiff --dir-diff'
|
|
```
|
|
|
|
## Usage
|
|
|
|
```bash
|
|
git dt <any git diff revision expression> # see `man gitrevisions`
|
|
git dt # Unstaged changes
|
|
git dt --staged # Staged changes
|
|
git dt HEAD~1 # Last commit
|
|
git di v1.0 v2.0 # diff between two tags
|
|
```
|
|
|
|
## Using custom vim command
|
|
|
|
Using clean vim without reading `vimrc`
|
|
```bash
|
|
git config --global difftool.vimtabdiff.cmd 'vimtabdiff.py --vim "vim --clean" $LOCAL $REMOTE'
|
|
```
|
|
|
|
Git config file (`~/.gitconfig`) should look like this
|
|
|
|
```TOML
|
|
[alias]
|
|
...
|
|
dt = difftool --tool vimtabdiff --dir-diff
|
|
[difftool "vimtabdiff"]
|
|
cmd = vimtabdiff.py --vim \"vim --clean\" $LOCAL $REMOTE
|
|
```
|
|
Using better diff algorithm
|
|
|
|
```bash
|
|
git config --global difftool.vimtabdiff.cmd 'vimtabdiff.py --vim "vim +\"set diffopt+=algorithm:patience\"" $LOCAL $REMOTE'
|
|
|
|
```
|
|
|
|
*Note:* Not tested in non-linux OS. But I guess it should work fine. Pull requests welcome if found any issues.
