: Run external application on markdown source in ikiwiki Can I add a button to each wiki page in ikiwiki which launches an external application (on the client side) or script with the markdown

@Candy875

How difficult this is would depend on what technologies you are using server-side and how readily available you can find existing code to convert HTML to LaTeX and PDF. However this should be a server-side thing, and shouldn't even be necessary to write to disk (temporary file like you say) unless you cared about caching. The links should point to server-side scripts that will convert the Markdown to HTML (assuming it's easier to convert to/from HTML than to/from Markdown directly) and then to either LaTeX or PDF and return the response using a header that will trigger download in the browser, such as:

Content-disposition: attachment; filename=your_page.tex


Edit: Looks like ikiwiki uses PERL. Here are some resources using that language:


PDF-FromHTML
html2tex

That is actually pretty difficult. All you can do is include links. Links can have certain protocols. For example when printing a www.whateverlink.com, your operating system is configured to open those with a web browser.

When using ftp:// for example, it will try to open the link with a ftp client. You can try to use a protocol used for markdown edition, but I doubt you'll find any standard for that.
