`config.git_blame` defaults to `true`; set it to `false` to disable current-line inline Git blame and its background worker. Only literal Ruby booleans are accepted; other values reject the configuration. Toggle it for the running session with `:git_blame.toggle`, its palette action, or a custom binding such as `config.bind "leader b", config.core.git_blame.toggle`. There is no default shortcut.
`config.git_gutter` defaults to `"bar"`: a fat `▌` beside each changed line number, followed by a blank before the text. `"symbols"` uses `+` / `-` / `~` instead. Added, removed, and modified lines use green, red, and yellow respectively. `"line_numbers"` colors the existing numbers without adding a marker column; the current line retains its cyan/bold caret highlight. `"none"` disables repository indicators, not line numbers. Other modes retain diagnostic number colors independently of repository markers. Unsupported strings, empty strings, and non-string values reject the configuration.
Indicators compare the current editor text (including unsaved edits) against Git `HEAD`, or the parent `@-` in Git-backed jj repositories, rather than against the last save or Git index. Line endings use the editor's LF normalization. They refresh after edits/saves, on focus regain, and once per second for repository changes. Historical snapshots do not receive live indicators. Eligible named files not yet on disk show nonempty unsaved text as added; tracked files missing on disk still compare their buffer text against the baseline. Non-repository, ignored, binary, symlink, and unsupported files have no indicators; neither do jj working changes with multiple parents. Both colocated and non-colocated Git-backed jj repositories are supported. Files above 16 MiB report an error and clear their indicators; request batches are limited to 64 MiB or 1024 files.
`config.diff_context_lines = 10` sets how many unchanged aligned lines appear above and below each diff change; it defaults to `10` and accepts nonnegative integers, including `0` for changes only. `config.diff_expand_lines = 15` sets how many additional lines each directional expansion reveals per keypress; it defaults to `15` and accepts positive integers. Both are bounded by the platform's Rust `usize` maximum (`18446744073709551615` on 64-bit systems). Floats, strings, booleans, negative or oversized values, and a zero expansion step reject the whole Ruby configuration.
`config.diff_view_mode` selects the initial view for each new comparison: `"split"` (default) or `"unified"`. `config.diff_split_orientation` selects `"vertical"` (left/right, default) or `"horizontal"` (above/below) for split views. Invalid values reject the configuration. Normal-mode **Space v** cycles split/unified; **Space s** flips split orientation. These controls affect the current comparison, not startup defaults, and retain their choices across file switches and tabs. Orientation changes apply only in split view.
