/**
|
|
* The `xdiff_emit_line_fn` function can return 1 to abort early, or 0
|
|
* to continue processing. Note that doing so is an all-or-nothing
|
|
* affair, as returning 1 will return all the way to the top-level,
|
|
* e.g. the xdi_diff_outf() call to generate the diff.
|
|
*
|
|
* Thus returning 1 means you won't be getting any more diff lines. If
|
|
* you need something in-between those two options you'll to use
|
|
* `xdl_emit_hunk_consume_func_t` and implement your own version of
|
|
* xdl_emit_diff().
|
|
*
|
|
* We may extend the interface in the future to understand other more
|
|
* granular return values. While you should return 1 to exit early,
|
|
* doing so will currently make your early return indistinguishable
|
|
* from an error internal to xdiff, xdiff itself will see that
|
|
* non-zero return and translate it to -1.
|
|
*
|
|
* See "diff_grep" in diffcore-pickaxe.c for a trick to work around
|
|
* this, i.e. using the "consume_callback_data" to note the desired
|
|
* early return.
