--- Run diff on strings {a} and {b}. Any indices returned by this function,
|
|
--- either directly or via callback arguments, are 1-based.
|
|
---
|
|
--- Examples:
|
|
---
|
|
--- ```lua
|
|
--- vim.diff('a\n', 'b\nc\n')
|
|
--- -- =>
|
|
--- -- @@ -1 +1,2 @@
|
|
--- -- -a
|
|
--- -- +b
|
|
--- -- +c
|
|
---
|
|
--- vim.diff('a\n', 'b\nc\n', {result_type = 'indices'})
|
|
--- -- =>
|
|
--- -- {
|
|
--- -- {1, 1, 1, 2}
|
|
--- -- }
|

---@param a string First string to compare
|
|
---@param b string Second string to compare
|
|
---@param opts table<string,any> Optional parameters:
|
|
--- - `on_hunk` (callback):
|
|
--- Invoked for each hunk in the diff. Return a negative number
|
|
--- to cancel the callback for any remaining hunks.
|
|
--- Args:
|
|
--- - `start_a` (integer): Start line of hunk in {a}.
|
|
--- - `count_a` (integer): Hunk size in {a}.
|
|
--- - `start_b` (integer): Start line of hunk in {b}.
|
|
--- - `count_b` (integer): Hunk size in {b}.
|
|
--- - `result_type` (string): Form of the returned diff:
|
|
--- - "unified": (default) String in unified format.
|
|
--- - "indices": Array of hunk locations.
|
|
--- Note: This option is ignored if `on_hunk` is used.
|
|
--- - `linematch` (boolean|integer): Run linematch on the resulting hunks
|
|
--- from xdiff. When integer, only hunks upto this size in
|
|
--- lines are run through linematch. Requires `result_type = indices`,
|
|
--- ignored otherwise.
|
|
--- - `algorithm` (string):
|
|
--- Diff algorithm to use. Values:
|
|
--- - "myers" the default algorithm
|
|
--- - "minimal" spend extra time to generate the
|
|
--- smallest possible diff
|
|
--- - "patience" patience diff algorithm
|
|
--- - "histogram" histogram diff algorithm
|
|
--- - `ctxlen` (integer): Context length
|
|
--- - `interhunkctxlen` (integer):
|
|
--- Inter hunk context length
|
|
--- - `ignore_whitespace` (boolean):
|
|
--- Ignore whitespace
|
|
--- - `ignore_whitespace_change` (boolean):
|
|
--- Ignore whitespace change
|
|
--- - `ignore_whitespace_change_at_eol` (boolean)
|
|
--- Ignore whitespace change at end-of-line.
|
|
--- - `ignore_cr_at_eol` (boolean)
|
|
--- Ignore carriage return at end-of-line
|
|
--- - `ignore_blank_lines` (boolean)
|
|
--- Ignore blank lines
|
|
--- - `indent_heuristic` (boolean):
|
|
--- Use the indent heuristic for the internal
|
|
--- diff library.
|
|
---
|
|
---@return string|table|nil
|
|
--- See {opts.result_type}. `nil` if {opts.on_hunk} is given.
