![]() I googled "markdown exclude from toc" and one reference mentioned including the following comment above the header: īut that approach didn't work for me in an online converter, and not sure how universally that approach is supported. ![]() Would get output like this: - * * Ī quality TOC should only have a single top-level item, so the recommended structure that I'm seeing online wouldn't auto-convert well by default. So a structure like this: #Name #Description #Section1 #Section2 Would be auto-generated and output like this: - * + So an md structure like this: #Level1 #Level2 #Level3 That looks fine to me but looks like some sites like github auto-generate a TOC based on the structure of the md. Seems like I'm seeing a general recommended pattern online to have a top-level "Name" section wrapped with (#) formatting, followed by a "Description" section wrapped with (#). I’ll see if I can figure that out.I'm working on my first README.md file. It would, of course, be nice if a PDF containing a visible TOC (which is the default when converting from MD) would allow for the TOC entries to be clickable and leading to the appropriate place in the document. The code is heavily commented (for my standards), and t here’s an explanation of the approach available elsewhere. Acrobat Reader shows it in its “Bookmark” section. It’s accessible as “Table of contents” in DT, Preview and PDFpen. Also, the TOC does not appear in the PDF document itself. I ran it on the source for the “CSS in Markdown” series, and it worked ok there. Note The script is not thoroughly tested, lacking suitable Markdown documents. That seemed reasonable to me, since an MD without a TOC shouldn’t be converted to a PDF with a TOC. Note that it will bail out if either the record passed in is not a Markdown document or it doesn’t contain a TOC directive. It’s a trivial exercise to transform the script so that handles a set of selected records. * Save the outline in the PDF document and save the document to disk */Īs it stands, the code works with a single Markdown whose UUID is given at the top. ParentOutline.insertChildAtIndex(tocEntry, parentOutline.numberOfChildren) TargetEntry = targetEntry.parent || outline * Current heading is smaller than last one: move upwards to find matching parent */ The function I’ve worked up is called rendertoc() and it allows you to drop in a table of contents anywhere inside an R Markdown document. * Current heading is on same level as last one: append to parent of last sibling */ * Current heading is bigger than last one: append to last one or outline for first heading */ ![]() * Find the appropraite parent PDFOutline to append this TOC entry to */ * Use the heading in the PDF doc as label for the TOC entry */ a target for the TOC entry */Ĭonst destination = $.(page, pt) Ĭonst tocEntry = $. Use the upper y coordinate and the left x coordinate */Ĭonst pt = $.NSPointFromCGPoint($.NSRectToCGRect(bounds).origin) * Calculate the point for the destination a click on the TOC entry is moving to. * If the text is found (as it should be) use the first match */Ĭonst page = // NSPage object!Ĭonst bounds = firstSel.boundsForPage(page) //NSRect object * Search for the textual version of the headline in the PDFDocument to find page and location on page */Ĭonst pdfSelection = pdfDoc.findStringWithOptions($(headingInPDF),0) (well, it should always be, but who konws) */ It might be prefixed with characters _not_ in the original one, like numbering */Ĭonst headingInPDF = pdfText.match(headingRE) * Find the headline in the PDF as it's printed there. * Convert the MD to PDF, get the PDFDocument from it and create the top-level Outline */Ĭonst pdfRecord = app.convert()$`,"m") The array headings than contains only those strings. The replace() removes all code fences, the matchAll greps all headlines and the map extracts the captured headline, * Find headings in MD file, skipping over code fences. * Bail out if MD document doesn't contain TOC directive */Ĭonsole.log("No TOC command in MD file.") * Bail out if not a Markdown document */ ObjC.import('CoreGraphics') //Needed only for NSPoint - CGPoint conversionĬonst UUID = '82E64F1D-6BFE-410D-96F4-ED8CFED0E2F5' // adjust or modify script to work with selected records Anyway, here it comes: ObjC.import('PDFKit') I’m sure it could be implemented in AppleScript as well, with considerably more typing. As can be expected, the script is written in JavaScript. I’m proposing a script to add an invisible TOC as metadata to a PDF document during its conversion from Markdown. But clicking on the links doesn’t do anything. That means: The TOC is visible, and it seems to contain links to the headlines. Some time ago, a forum participant noted that the PDF generated from a Markdown document in DT doesn’t contain a usable table of contents (TOC).
