From b21d164275b9186421ebe39498be47ea9f171694 Mon Sep 17 00:00:00 2001 From: Kipras Melnikovas Date: Sat, 17 Feb 2024 18:27:18 +0200 Subject: mergetools: vimdiff: use correct tool's name when reading mergetool config 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.
