Problem: git quotes filenames containing spaces, unicode, or special
characters (e.g. M "path with spaces/file.lua"). parse_file_line
passed the quotes through, causing file-not-found on diff operations.
Solution: add unquote() helper that strips surrounding quotes and
unescapes \\, \", \n, \t, and octal \NNN sequences. Apply it to both
filename returns in parse_file_line.
## Problem
Pressing `du` on a `UU` (unmerged) file in the fugitive status buffer
had no
effect. There was no way to see a proper ours-vs-theirs diff with syntax
highlighting and intra-line changes, or to resolve conflicts from within
a
unified diff view.
Additionally, pressing `du` on a section header containing only unmerged
files
showed "no changes in section" because `git diff` produces combined
(`diff --cc`)
output for unmerged files, which was stripped entirely.
## Solution
Fetch `:2:` (ours) and `:3:` (theirs) from the git index and generate a
standard
unified diff. The existing highlight pipeline (treesitter + intra-line)
applies
automatically. Resolution keymaps (`doo`/`dot`/`dob`/`don`) on hunks in
the diff
view write changes back to the working file's conflict markers.
Navigation
(`]x`/`[x`) jumps between unresolved conflict hunks.
For section diffs, combined diff entries are now replaced with generated
ours-vs-theirs unified diffs instead of being stripped.
Works for merge, cherry-pick, and rebase conflicts — git populates
`:2:`/`:3:`
the same way for all three.
Closes#61
When pressing `du`/`dU` from a hunk line in the fugitive status buffer
(after expanding with `=`), the unified diff now opens at the
corresponding line instead of line 1.
Implementation:
- `fugitive.get_hunk_position()` returns @@ header and offset when on a hunk line
- `commands.find_hunk_line()` finds matching @@ header in diff buffer
- `commands.gdiff_file()` accepts optional `hunk_position` and jumps after opening
Also updates @phanen's README credit for the previous two fixes.
Closes#65
Parse both old and new filenames from rename lines (R old -> new).
When diffing staged renames, use old filename as base to correctly
show content changes rather than treating the file as entirely new.
Also adds comprehensive tests for filename edge cases:
- Double extensions, hyphens, underscores, dotfiles
- Deep nested paths, complex renames
- Documents known limitation with filenames containing ' -> '
Section headers (Staged/Unstaged) now show all diffs in that section,
matching fugitive's behavior. Untracked files show as all-added diffs.
Deleted files show as all-removed diffs.
Also handles edge cases:
- Empty new/old content for deleted/new files
- Section header detection returns is_header flag
Adds du/dU keymaps to fugitive's :Git status buffer for opening unified
diffs instead of side-by-side diffs:
- du opens horizontal split (mirrors dd)
- dU opens vertical split (mirrors dv)
Parses status buffer lines to extract filename and detect section
(staged/unstaged/untracked). For staged files, diffs index vs HEAD.
For unstaged files, diffs working tree vs index.
Configurable via vim.g.diffs.fugitive.horizontal/vertical (set to
false to disable).
