In case anyone else has a similar issue using the textile or markdown plugins I thought I’d offer this bit before someone else goes bald.
I wanted textile formatting for comments and so I added the {exp:textile}{/exp:textile}around my {comment} in the template. For some reason though the only textile options that seemed to be working were _emphasis_ and *strong*. But, if I added some text on a line before using a textile block option like a blockquote (bq.) then the blockquote textile would work.
That’s not exactly optimal. It would odd to tell commenters they needed to preface certain textile markup with a line of plain text.
The solution? Whitespace. I had indented the {comment} between the opening and closing textile option like so:
{exp:textile}
{comment}
{/exp:textile}That dunna work. In your template it should look like this:
{exp:textile}{comment}{/exp:textile}No whitespace, no line-breaks.
The same should hold true for Markdown as well as when dealing with {body} or any portion of your template that you want formatted with these modifiers. Also, text formatting should be set to none wherever you’re using them. Hope this wasn’t too obvious for everyone else lest I feel foolish. 😊
