HTML/images zipped?

HTML/images zipped?

[Peter Davis]

Is there any way to export HTML with all references images,
etc. packaged in a ZIP file?

Thank you.

My guess is that at the moment your best bet is hacking some together with
ox-publish.  See org-publish-project-alist.

Hope it helps,
Rasmus

PS: On the list, we have talked about a .borg format that might serve for
similar situation but it's at an idea stage at the moment.

data-uri's is probably what you want. There is no standard format for
zipping multiple HTML files together, while including images (or video's
or audio) directly into the HTML works reasonably well.

I found a snippet to get ox-html to do this -- it would be a good
feature to add properly though!

Thanks, Rasmus. I'll take a look when I have a chance, but for now, I'll
have to zip the files by hand.

Thanks!

Thanks, Phillip. That sounds like an interesting possibility. I've never
worked with data-uri's. Can you post or send that snippet? I don't seem
to be finding it on my initial searches.

Re: HTML/images zipped?

[John Kitchin]

I did something like this for org-files:
https://github.com/jkitchin/jmax/blob/master/ox-archive.el

You might use that as a starting point for html.

Also, my blogofile code
(https://github.com/jkitchin/jmax/blob/master/user/blogofile.el) does
something like this to publish org to blogofile.

That is a cool idea. Here is some code for data uris that worked on with
org-mode earlier this summer. You could definitely hack a filter that
embedded the image uri directly into the exported html.

Thanks, John. I will take a closer look at both of these.

I'm not lisp-savvy, but I've been experimenting with this. I get an
error:

Unknown "nil" backend: Aborting export

It seems to be coming from these lines:

      (let ((org-export-filter-link-functions '(ox-mrkup-filter-link)))
	(org-org-export-as-org)))

I'm not sure how or where backend is supposed to be defined.

Also, I guess it would take some tweaking to export to HTML and save
that in the ZIP, instead of the original org file.

Any hints welcome.

Thanks!

Re: HTML/images zipped?

[John Kitchin]

I am not sure. I have this in my init file:

(require 'ox-org)

maybe that is required for you too?

I tried this on some arbitrary org file (not containing any references) and I got an error:

    (insert (format "# archived from %s on %s\n"

    ;; add bibliography references if they exist. 
    (org-ref-extract-bibtex-entries)
    ...
--8<---------------cut here---------------end--------------->8---

because the first thing that org-ref-extract-bibtex-entries does is

--8<---------------cut here---------------start------------->8---
  (let* ((temporary-file-directory (file-name-directory (buffer-file-name)))
--8<---------------cut here---------------end--------------->8---

and (buffer-file-name) returns nil on the *Org ORG Export* buffer.
But since you obviously use this code successfully, I wonder why
you don't hit this.

Thanks for any help,
Nick

Re: HTML/images zipped?

[John Kitchin]

hm... maybe it has been a while since I ran that ;) I pushed some
changes that seem to have it working on a small test file.

This code is somewhat on the border of a filter/custom export. There are
probably links that will now work with it, I have not tested it super
thoroughly.

Notably, it does not preserve relative paths, but rather renames files
and images and replaces the links in the org-file with the new
names. It was too hard to figure out how to preserve the paths when I
wrote this originally.

Re: HTML/images zipped?

[Robert Klein]

[-- Attachment #1: Type: text/plain, Size: 993 bytes --]

Hello,

please find an experimental htmlzip exporter attached.

Publishing doesn't work, yet (and would, as I began to write it,
export to individual zip files -- one per published org file --
instead of a single zip file).

It is a derived HTML exporter.  I took a lot of stuff from the
corresponding functions in the HTML and LaTeX exporter.

I'm putting an advice on org-html--format-image during "zip" export to
get a list of inline images, so I can put them together with the html
in the zip file.  (Another possibility would be to `rewrite' the
functions org-html-latex-environment, org-html-latex-fragment, and
org-html-link as translate functions for the new exporter (with the
only purpose to run a org-htmlzip--image-list instead of
org-html--image-list).

Best regards
Robert

Cool!

I don't know if you indent to make this an extension to org or for this to
be a quick hack to solve a particular issue.

If the former: Shouldn't this rather be something that is configurable
from via a keyword in ox-html or more logically via ox-publish (which can
consist of several files)?  If so, you could store the list of files in
the info communication channel rather than org-htmlzip--image-list.

The command used for compression should be configurable.

Also, if the point is to produce an offline version, you should also
include scripts and css files.

Thanks,
Rasmus

This is EPUB format (more or less).

I thought about aiming for contrib, but if it turns out not to be too
invasive I'll probably ask for inclusion in ox-html.

Hmm, I think for individual files C-c C-e h a(rchive) and an option for
publishing (e.g. in org-publish-project-alist)


> The command used for compression should be configurable.
 Yes, per org-publish-project-alist and global at least, I think.
 Could be I'd need to `register' (e.g.
 org-export-archivers-alist) compressions commands in .emacs, so
 a #+OPTION doesn't get too complicated (I'd think something like
 `z:tgz' is acceptable, but e.g. `z:'("tar" "-jcvf") is not...

Agreed.

I'll see how far I get in the next couple of days.

Thank you very much for your suggestions!
