It looks kind of discouraging. Now most readers support some kind of JavaScript, but that support is not clearly specified in the standard. So using MathJax may be possible on some devices, but not on others. I'll keep looking on how to best implement this. Cheers, Mark -- Mark Meyer m...@ofosos.org

I guess I Eric> could simply try it... which I'll aim to do this week. Tables should be no problem. Equations I'll say are not supported. I'd assume you want MathML support, this was delivered with EPUB 3.0.1, while we're currently targeting EPUB 2.0.1. Let me look into that. Cheers, Mark -- Mark Meyer m...@ofosos.org
[O] ANN/RFC: ox-epub
Hi, this is to announce that ox-epub is now in a somewhat working state and pretty much aligned with the rest of the ox framework. https://github.com/ofosos/ox-epub The current release is 0.2.1 which is right now syncing to MELPA stable. If you want to generate EPUB directly from org mode, please give it a spin. The output should always be reasonable and readable in an ebook reader, but I'm also interested in a more formal way of checking correctsness. So if you're at it, you may try https://github.com/IDPF/epubcheck which will give you a detailed listing of problems with the generated epub. If you or epubcheck find any reason to complain, please don't hesitate to open a bug on github, or by directly mailing to me. Please attach any relevant data, in general the output of epubcheck might be sufficient. I will try to solve any issues without requesting your data. Hope you like it. Cheers, Mark -- Mark Meyer m...@ofosos.org
[O] Using org-export-get-reference for strings
Hi list, In ox-epub I'm using several references to external stylesheets, starting with the external name in the user filesystem I transform these into a kind-of unique id that lives in the EPUB zip file. Currently I'm doing this using a counter, generating zip entries in the form of style-1.css. Can I use `org-export-get-reference' to generate these ids? I would likely pass a simple string as the object to get a reference to (the path the external stylesheet lives at). >From what I understand this would generate different references for `foobar.css' and `../foobar.css' even when these are identical documents. This should be fixed by passing `(expand-file-name style)' to `org-export-get-reference'. I'm not quite sure I understand `org-export-get-reference' correctly, can you elucidate this? Cheers, Mark -- Mark Meyer m...@ofosos.org

[O] ox-odt backend use of org-export-async-start
Hi, I'm presently looking through ox-odt/org-odt-export-to-odt. I uses a quasiquote to include a parameter in the anonymous function that is then passed to org-export-async-start. Is there any reason to do this? I would assume with lexical variables this would be superflouus. Cheers, Mark -- Mark Meyer m...@ofosos.org

[O] ox-epub
Hi list, I'm the author of ox-epub, which is a very recent extension to org-mode to author EPUB files directly via the org export layer. Pank (Rasmus) asked on Github, whether this could be part of org-mode. I'm all for it. I gather this would be added to the lisp/contrib directory? Are there any technical barriers to continuing development on ox-epub to me? The legal stuff is not an issue to me. Do you find the addition worthwile? Speak your mind.

[O] Error on html export
Hi,
I'm getting an error on HTML export, as soon as my document has a
`#+TITLE' set.
Here's part of the stack trace:
Debugger entered--Lisp error: (wrong-type-argument listp #("test" 0 4
(:parent (#1
org-element-set-contents(#("test" 0 4 (:parent (#0
apply(org-element-set-contents #("test" 0 4 (:parent (#0))) nil)
#[257 "\211\305\306\307#\310\311\211:\204
I see that `org-element-set-contents' expects a list to operate on, but
is getting passed an array. This is with org-mode 9.0.5.
Cheers, Mark

I defined `*org-epub-current-file*' as a special variable and set it in the publish function. Then I extracted the headlines in `org-epub-template' (should find a better place). And this works like a charm. And now I can use the same heading text multiple times and get a proper export. Thank you very much. Cheers, Mark -- Mark Meyer m...@ofosos.org

I thought about doing the zipping in `org-epub', but had to get some other stuff working first. But you already wrote the code :) Cheers, Mark -- Mark Meyer m...@ofosos.org

You're completely right. The use case is, folding multiple documents into a single EPUB (via a project), but I can easily write the partial tocs into one/multiple temp buffers and copy them over after that. Thanks.

I am under the impression that I don't have access to the `INFO' plist that is required by `org-export-get-reference' - at least not from the `:completion-function'.

I wrote it yesterday, the code's up at https://github.com/ofosos/org-epub it's a little crufty, because I did write it for org 8 initially. Hmm, I have to think about it. I would like to either have a 1:1 mapping between the elements `org-element' delvers and the links the export backend generates or create a function that runs before the export that generates :custom_id properties for every element that doesn't have one. This was easier in org 8, since every internal link was just something like `sec-8-2'. Thanks for you quick replies. Cheers, Mark -- Mark Meyer m...@ofosos.org

Is this a property that is available via org-element or do I have to set this in the source document? I'm trying to link to all the headlines from a table of contents (EPUB expoerter). Basically I'm using a `:completion-function' to generate all the meta data and I need to link to most of the headlines down to a certain level during the toc generation. Thanks.

[O] Searching for a headline
Hi, I'm using org-publish-external-link to look up a the link target for a headline. The following code works, although I'd expect it to fail: (org-publish-resolve-external-link (concat "* " (org-element-property :raw-value headline)) source-file) ``headline'' is a headline as returned by org-element, while ``source-file'' is a ``.org'' file. I'd expect that this needs to be (org-publish-resolve-external-link (concat (make-string (org-element-property :level headline) ?*) " " (org-element-property :raw-value headline)) source-file) I.e. for a level 3 headline it should be ``*** foobar'' and not ``* foobar''. ``org-publish-resolve-external-link'' uses ``org-export-string-to-search-cell'' internally. Can someone point me to some docuentation on how the searching works? Cheers, Mark -- Mark Meyer m...@ofosos.org
