The /mergetools/vimdiff script, which handles both vimdiff, nvimdiff
and gvimdiff mergetools (the latter 2 simply source the vimdiff script), has a
function merge_cmd() which read the layout variable from git config, and it
would always read the value of mergetool.**vimdiff**.layout, instead of the
mergetool being currently used (vimdiff or nvimdiff or gvimdiff).
It looks like in 7b5cf8be18 (vimdiff: add tool documentation, 2022-03-30),
we explained the current behavior in Documentation/config/mergetool.txt:
```
mergetool.vimdiff.layout::
The vimdiff backend uses this variable to control how its split
windows look like. Applies even if you are using Neovim (`nvim`) or
gVim (`gvim`) as the merge tool. See BACKEND SPECIFIC HINTS section
```
which makes sense why it's explained this way - the vimdiff backend is used by
gvim and nvim. But the mergetool's configuration should be separate for each tool,
and indeed that's confirmed in same commit at Documentation/mergetools/vimdiff.txt:
```
Variants
Instead of `--tool=vimdiff`, you can also use one of these other variants:
* `--tool=gvimdiff`, to open gVim instead of Vim.
* `--tool=nvimdiff`, to open Neovim instead of Vim.
When using these variants, in order to specify a custom layout you will have to
set configuration variables `mergetool.gvimdiff.layout` and
`mergetool.nvimdiff.layout` instead of `mergetool.vimdiff.layout`
```
So it looks like we just forgot to update the 1 part of the vimdiff script
that read the config variable. Cheers.
Though, for backward compatibility, I've kept the mergetool.vimdiff
fallback, so that people who unknowingly relied on it, won't have their
setup broken now.

mergetool.<tool>.path::
|
|
Override the path for the given tool. This is useful in case
|
|
your tool is not in the PATH.
|
|
|
|
mergetool.<tool>.cmd::
|
|
Specify the command to invoke the specified merge tool. The
|
|
specified command is evaluated in shell with the following
|
|
variables available: 'BASE' is the name of a temporary file
|
|
containing the common base of the files to be merged, if available;
|
|
'LOCAL' is the name of a temporary file containing the contents of
|
|
the file on the current branch; 'REMOTE' is the name of a temporary
|
|
file containing the contents of the file from the branch being
|
|
merged; 'MERGED' contains the name of the file to which the merge
|
|
tool should write the results of a successful merge.
|
|
|
|
mergetool.<tool>.hideResolved::
|
|
Allows the user to override the global `mergetool.hideResolved` value
|
|
for a specific tool. See `mergetool.hideResolved` for the full
|
|
description.
|
|
|
|
mergetool.<tool>.trustExitCode::
|
|
For a custom merge command, specify whether the exit code of
|
|
the merge command can be used to determine whether the merge was
|
|
successful. If this is not set to true then the merge target file
|
|
timestamp is checked, and the merge is assumed to have been successful
|
|
if the file has been updated; otherwise, the user is prompted to
|
|
indicate the success of the merge.
|
|
|
|
mergetool.meld.hasOutput::
|
|
Older versions of `meld` do not support the `--output` option.
|
|
Git will attempt to detect whether `meld` supports `--output`
|
|
by inspecting the output of `meld --help`. Configuring
|
|
`mergetool.meld.hasOutput` will make Git skip these checks and
|
|
use the configured value instead. Setting `mergetool.meld.hasOutput`
|
|
to `true` tells Git to unconditionally use the `--output` option,
|
|
and `false` avoids using `--output`.
|
|
|
|
mergetool.meld.useAutoMerge::
|
|
When the `--auto-merge` is given, meld will merge all non-conflicting
|
|
parts automatically, highlight the conflicting parts, and wait for
|
|
user decision. Setting `mergetool.meld.useAutoMerge` to `true` tells
|
|
Git to unconditionally use the `--auto-merge` option with `meld`.
|
|
Setting this value to `auto` makes git detect whether `--auto-merge`
|
|
is supported and will only use `--auto-merge` when available. A
|
|
value of `false` avoids using `--auto-merge` altogether, and is the
|
|
default value.
|
|
|
|
mergetool.<vimdiff variant>.layout::
|
|
Configure the split window layout for vimdiff's `<variant>`, which is any of `vimdiff`,
|
|
`nvimdiff`, `gvimdiff`.
|
|
Upon launching `git mergetool` with `--tool=<variant>` (or without `--tool`
|
|
if `merge.tool` is configured as `<variant>`), Git will consult
|
|
`mergetool.<variant>.layout` to determine the tool's layout. If the
|
|
variant-specific configuration is not available, `vimdiff`'s is used as
|
|
fallback. If that too is not available, a default layout with 4 windows
|
|
will be used. To configure the layout, see the `BACKEND SPECIFIC HINTS`

mergetool.hideResolved::
|
|
During a merge, Git will automatically resolve as many conflicts as
|
|
possible and write the 'MERGED' file containing conflict markers around
|
|
any conflicts that it cannot resolve; 'LOCAL' and 'REMOTE' normally
|
|
represent the versions of the file from before Git's conflict
|
|
resolution. This flag causes 'LOCAL' and 'REMOTE' to be overwritten so
|
|
that only the unresolved conflicts are presented to the merge tool. Can
|
|
be configured per-tool via the `mergetool.<tool>.hideResolved`
|
|
configuration variable. Defaults to `false`.
|
|
|
|
mergetool.keepBackup::
|
|
After performing a merge, the original file with conflict markers
|
|
can be saved as a file with a `.orig` extension. If this variable
|
|
is set to `false` then this file is not preserved. Defaults to
|
|
`true` (i.e. keep the backup files).
|
|
|
|
mergetool.keepTemporaries::
|
|
When invoking a custom merge tool, Git uses a set of temporary
|
|
files to pass to the tool. If the tool returns an error and this
|
|
variable is set to `true`, then these temporary files will be
|
|
preserved; otherwise, they will be removed after the tool has
|
|
exited. Defaults to `false`.
|
|
|
|
mergetool.writeToTemp::
|
|
Git writes temporary 'BASE', 'LOCAL', and 'REMOTE' versions of
|
|
conflicting files in the worktree by default. Git will attempt
|
|
to use a temporary directory for these files when set `true`.
|
|
Defaults to `false`.
|
|
|
|
mergetool.prompt::
|
|
Prompt before each invocation of the merge resolution program.
|
|
|
|
mergetool.guiDefault::
|
|
Set `true` to use the `merge.guitool` by default (equivalent to
|
|
specifying the `--gui` argument), or `auto` to select `merge.guitool`
|
|
or `merge.tool` depending on the presence of a `DISPLAY` environment
|
|
variable value. The default is `false`, where the `--gui` argument
|
|
must be provided explicitly for the `merge.guitool` to be used.
