The third - parameter may be NULL or can be prefix path, and then the `.prefix` - variable will be set to it. This is typically the first function you - want to call when you want to deal with a revision list. After calling - this function, you are free to customize options, like set - `.ignore_merges` to 0 if you don't want to ignore merges, and so on. See - `revision.h` for a complete list of available options. - -`add_pending_object`:: - - This function can be used if you want to add commit objects as revision - information. You can use the `UNINTERESTING` object flag to indicate if - you want to include or exclude the given commit (and commits reachable - from the given commit) from the revision list. -+ -NOTE: If you have the commits as a string list then you probably want to -use setup_revisions(), instead of parsing each string and using this -function. - -`setup_revisions`:: - - Parse revision information, filling in the `rev_info` structure, and - removing the used arguments from the argument list. Returns the number - of arguments left that weren't recognized, which are also moved to the - head of the argument list. The last parameter is used in case no - parameter given by the first two arguments. - -`prepare_revision_walk`:: - - Prepares the rev_info structure for a walk. You should check if it - returns any error (non-zero return code) and if it does not, you can - start using get_revision() to do the iteration. - -`get_revision`:: - - Takes a pointer to a `rev_info` structure and iterates over it, - returning a `struct commit *` each time you call it. The end of the - revision list is indicated by returning a NULL pointer. - -`reset_revision_walk`:: - - Reset the flags used by the revision walking api. You can use - this to do multiple sequential revision walks. - -Data structures ---------------- - -Talk about <revision.h>, things like: - -* two diff_options, one for path limiting, another for output; -* remaining functions; - -(Linus, JC, Dscho) |
