Output is printed to stdout. + The last line printed does not contain a terminating newline. Returns 1 if + output was printed, and 0 if no output was necessary. + +* `graph_show_strbuf()` prints the specified strbuf to stdout, prefixing all + lines but the first with a graph line. The caller is responsible for + ensuring graph output for the first line has already been printed to stdout. + (This can be done with `graph_show_commit()` or `graph_show_oneline()`.) If + a NULL graph is supplied, the strbuf is printed as-is. + +* `graph_show_commit_msg()` is similar to `graph_show_strbuf()`, but it also + prints the remainder of the graph, if more lines are needed after the strbuf + ends. It is better than directly calling `graph_show_strbuf()` followed by + `graph_show_remainder()` since it properly handles buffers that do not end in + a terminating newline. The output printed by `graph_show_commit_msg()` will + end in a newline if and only if the strbuf ends in a newline. + +Data structure +-------------- +`struct git_graph` is an opaque data type used to store the current graph +state. + +Calling sequence +---------------- + +* Create a `struct git_graph` by calling `graph_init()`. When using the + revision walking API, this is done automatically by `setup_revisions()` if + the '--graph' option is supplied. + +* Use the revision walking API to walk through a group of contiguous commits. + The `get_revision()` function automatically calls `graph_update()` each time + it is invoked. + +* For each commit, call `graph_next_line()` repeatedly, until + `graph_is_commit_finished()` returns non-zero. Each call go + `graph_next_line()` will output a single line of the graph. The resulting + lines will not contain any newlines. `graph_next_line()` returns 1 if the + resulting line contains the current commit, or 0 if this is merely a line + needed to adjust the graph before or after the current commit. This return + value can be used to determine where to print the commit summary information + alongside the graph output. + +Limitations +----------- + +* `graph_update()` must be called with commits in topological order. It should + not be called on a commit if it has already been invoked with an ancestor of + that commit, or the graph output will be incorrect. + +* `graph_update()` must be called on a contiguous group of commits. If + `graph_update()` is called on a particular commit, it should later be called + on all parents of that commit. Parents must not be skipped, or the graph + output will appear incorrect. ++ +`graph_update()` may be used on a pruned set of commits only if the parent list +has been rewritten so as to include only ancestors from the pruned set. + +* The graph API does not currently support reverse commit ordering. In + order to implement reverse ordering, the graphing API needs an + (efficient) mechanism to find the children of a commit. + +Sample usage +------------ + +------------ +struct commit *commit; +struct git_graph *graph = graph_init(opts); + +while ((commit = get_revision(opts)) != NULL) { + graph_update(graph, commit); + while (!graph_is_commit_finished(graph)) + { + struct strbuf sb; + int is_commit_line; + + strbuf_init(&sb, 0); + is_commit_line = graph_next_line(graph, &sb); + fputs(sb.buf, stdout); + + if (is_commit_line) + log_tree_commit(opts, commit); + else + putchar(opts->diffopt.line_termination); + } +} + +graph_release(graph); +------------ + +Sample output +------------- + +The following is an example of the output from the graph API.
