mergetools/vimdiff: add vimdiff1 merge tool variant

2021-02-23T19:37:13Z

This adds yet another vimdiff/gvimdiff variant and presents conflicts as a two-way diff between 'LOCAL' and 'REMOTE'. 'MERGED' is not opened which deviates from the norm so usage text is echoed as a Vim message on startup that instructs the user with how to proceed and how to abort. Vimdiff is well-suited to two-way diffs so this is an option for a more simple, more streamlined conflict resolution. For example: it is difficult to communicate differences across more than two files using only syntax highlighting; default vimdiff commands to get and put changes between buffers do not need the user to manually specify a source or destination buffer when only using two buffers. Like other merge tools that directly compare 'LOCAL' with 'REMOTE', this tool will benefit when paired with the new `mergetool.hideResolved` setting.

mergetool--lib: improve support for vimdiff-style tool variants

2020-07-29T21:44:46Z

The merge tools vimdiff2, vimdiff3, gvimdiff2, gvimdiff3 and bc3 are all variants of the main tools vimdiff and bc. They are implemented in the main and a one-liner script that just sources it exist for each. Allow variants ending in [0-9] to be correctly wired without the need for such one-liners, so instead of 5 scripts, only 1 (gvimdiff) is needed. Signed-off-by: pudinha Signed-off-by: Junio C Hamano

mergetools/vimdiff: trust Vim's exit code

2016-11-29T18:57:41Z

Allow vimdiff users to signal that they do not want to use the result of a merge by exiting with ":cquit", which tells Vim to exit with an error code. This is better than the current behavior because it allows users to directly flag that the merge is bad, using a standard Vim feature, rather than relying on a timestamp heuristic that is unforgiving to users that save in-progress merge files. The original behavior can be restored by configuring mergetool.vimdiff.trustExitCode to false. Reported-by: Dun Peal Signed-off-by: David Aguilar Signed-off-by: Junio C Hamano

mergetool: honor mergetool.$tool.trustExitCode for built-in tools

2016-11-29T18:54:03Z

Built-in merge tools contain a hard-coded assumption about whether or not a tool's exit code can be trusted to determine the success or failure of a merge. Tools whose exit codes are not trusted contain calls to check_unchanged() in their merge_cmd() functions. A problem with this is that the trustExitCode configuration is not honored for built-in tools. Teach built-in tools to honor the trustExitCode configuration. Extend run_merge_cmd() so that it is responsible for calling check_unchanged() when a tool's exit code cannot be trusted. Remove check_unchanged() calls from scriptlets since they are no longer responsible for calling it. When no configuration is present, exit_code_trustable() is checked to see whether the exit code should be trusted. The default implementation returns false. Tools whose exit codes can be trusted override exit_code_trustable() to true. Reported-by: Dun Peal Signed-off-by: David Aguilar Signed-off-by: Junio C Hamano

mergetool: reorder vim/gvim buffers in three-way diffs

2016-02-12T18:14:09Z

When invoking default (g)vimdiff three-way merge, the merged file is loaded as the first buffer but moved to the bottom as the fourth window. This causes a disconnect between vim commands that operate on window positions (e.g. CTRL-W_w) and those that operate on buffer index (e.g. do/dp). This change reorders the buffers to have the same index as windows while keeping the cursor default to the merged result as the bottom window.

mergetools: add vimdiff3 mode

2014-04-22T19:49:07Z

It's similar to the default, except that the other windows are hidden. This ensures that removed/added colors are still visible on the main merge window, but the other windows not visible. Specially useful with merge.conflictstyle=diff3. Signed-off-by: Felipe Contreras Acked-by: David Aguilar Signed-off-by: Junio C Hamano

mergetools: simplify how we handle "vim" and "defaults"

2013-01-29T03:00:38Z

Remove the exceptions for "vim" and "defaults" in the mergetool library so that every filename in mergetools/ matches 1:1 with the name of a valid built-in tool. Define the trivial fallback definition of shell functions in-line in git-mergetool-lib script, instead of dot-sourcing them from another file. The result is much easier to follow.
