POHow do I create a history graph
text
Body
copied!<p>I am trying to get enough information to create a history graph using libgit2 but am unsure how I get things like branch names for commits as appropriate.</p> <p>I want to reproduce something like that which is produced with the following git command:</p> <pre><code>git log --oneline --graph --decorate --all </code></pre> <p>This is the code I am using:</p> <pre><code>git_commit* old_head = NULL; error = git_revparse_single( (git_object**) &old_head, open_repo, "refs/heads/master" ); if( error != 0 ) { return SG_PLUGIN_OK; } const git_oid *head_oid = git_object_id( (git_object*)old_head ); git_revwalk *walk; git_revwalk_new( &walk, open_repo ); git_revwalk_sorting( walk, GIT_SORT_TOPOLOGICAL | GIT_SORT_TIME ); git_revwalk_push( walk, head_oid ); const git_signature *cauth; const char *cmsg; git_time_t ctime; git_oid newoid; while( ( git_revwalk_next( &newoid, walk ) ) == 0 ) { git_commit *wcommit; error = git_commit_lookup( &wcommit, open_repo, &newoid ); if( error != 0 ) { return SG_PLUGIN_OK; } ctime = git_commit_time( wcommit ); cmsg = git_commit_message( wcommit ); cauth = git_commit_author( wcommit ); TRACE("\t%s (%s at %d)\n", cmsg, cauth->email, ctime ); git_commit_free( wcommit ); } git_revwalk_free( walk ); </code></pre> <p>I can traverse the commits but i have several issues with the code above:</p> <ul> <li>i just get commits of the main master branch, if i iterate the code changing the revparse_single for each branch name then I get all commits but some are obviously duplicated where the commit is under more than one branch</li> <li>I just get commit msg, author and time, so how do i find out what the branch names are?</li> <li>Am I doing it right?</li> </ul>
