Question

I have spent two days researching for a library or some sort of PHP function to parse the git patch GitHub’s API returns and I can’t find anything I can use.

I was able to take out a decent amount of code from Phabricator, but it just has too many dependencies.

Does anyone know of php code that will parse something like the following:

Into an html table like this:

Thank you in advance 🙂

Here is what i’ve come up with.

        <? foreach( $commit['files'] as $file ) { ?>
        <div><h3><?=$file['filename']?></h3>
           <?
            $firstLine = true;
            $patch = explode("@@",$file['patch']);
            $lines_info = explode(",",$patch[1]);
            $st_ln_num = substr($lines_info[0], 2);
            $start_line['original'] = $st_ln_num;
            $start_line['left'] = $st_ln_num;
            $start_line['right'] = $st_ln_num;
            $lines = explode("\n",$file['patch']);
            ?>
            <div style="overflow: auto">
            <table class="parseDiff" cellpadding="0" cellspacing="0">
                <? foreach ($lines as $line) {
                    if (! $firstLine) {
                            $line_left = "";
                            $line_right = "";
                            $char = strlen($line) ? $line[0] : '~';
                            $type = "neutral";
                            switch ($char) {
                                case '-':
                                    $line_left = $start_line['left']++;

                                    break;
