DESCRIPTION

The markdown format supported in this implementation includes Pandoc-style header and inline <style> blocks, and the standard markdown(3) functions do not provide access to the data provided by either of those extensions. These functions give you access to that data, plus they provide a finer-grained way of converting Markdown documents into HTML.

Given a MMIOT* generated by mkd_in() or mkd_string(), mkd_compile() compiles the document into <style>, Pandoc, and html sections.

Once compiled, the document can be examined and written by the mkd_css(), mkd_document(), mkd_generatecss(), mkd_generatehtml(), mkd_generatetoc(), mkd_toc(), mkd_xhtmlpage(), mkd_doc_title(), mkd_doc_author(), and mkd_doc_date() functions.

mkd_css() allocates a string and populates it with any <style> sections provided in the document, mkd_generatecss() writes any <style> sections to the output, mkd_document() points text to the text of the document and returns the size of the document, mkd_generatehtml() writes the rest of the document to the output, and mkd_doc_title(), mkd_doc_author(), mkd_doc_date() are used to read the contents of a Pandoc header, if any.

mkd_xhtmlpage() writes a xhtml page containing the document. The regular set of flags can be passed.

mkd_toc() writes a document outline, in the form of a collection of nested lists with links to each header in the document, into a string allocated with malloc(), and returns the size.

mkd_generatetoc() is like mkd_toc(), except that it writes the document outline to the given FILE* argument.

mkd_cleanup() deletes a MMIOT* after processing is done.

mkd_compile() accepts the same flags that markdown() and mkd_string() do;

MKD_NOIMAGE: Do not process `![]' and remove <img> tags from the output.
MKD_NOLINKS: Do not process `[]' and remove <a> tags from the output.
MKD_NOPANTS: Do not do Smartypants-style mangling of quotes, dashes, or ellipses.
MKD_TAGTEXT: Process the input as if you were inside a html tag. This means that no html tags will be generated, and mkd_compile() will attempt to escape anything that might terribly confuse a web browser.
MKD_NO_EXT: Do not process any markdown pseudo-protocols when handing [][] links.
MKD_NOHEADER: Do not attempt to parse any Pandoc-style headers.
MKD_TOC: Label all headers for use with the mkd_generatetoc() function.
MKD_1_COMPAT: MarkdownTest_1.0 compatibility flag; trim trailing spaces from the first line of code blocks and disable implicit reference links.
MKD_NOSTRIKETHROUGH: Disable strikethrough support.

RETURN VALUES

The function mkd_compile() returns 1 in the case of success, or 0 if the document is already compiled. The function mkd_generatecss() returns the number of bytes written in the case of success, or EOF if an error occurred. The function mkd_generatehtml() returns 0 on success, -1 on failure.

BUGS

Error handling is minimal at best.
