Embed only local resources

Embed only local resources

[news-WPTjrydoUPgeaOpM6FAJmQkbCANdLtlA]

[-- Attachment #1.1: Type: text/plain, Size: 995 bytes --]

 

Is there a way to embedded in HTML output only all 
local/relative/file-system resources to make the HTML file relocatable?? 
Main use case is to embed a CSS file I specify on the command line:

 

pandoc -css mystyles.css mydoc.md

 

I tried using `--self-contained`, but pandoc then wants to embed not only 
local resources but external images as well which is not needed and can 
blow up the file size considerable.

The problem is particularly pressing when you have external images with 
*https* URLs: Pandoc does fail with "HttpExceptionRequest Request" and 
produces no output at all.

 

So how can I generate an HTML which contains the local resource 
(particularly the CSS), but does not attempt to download external URL 
resources?

Re: Embed only local resources

[John MacFarlane]

If you just want to embed a css file, you could try using
--include-in-header.  (In this case, you'd need to include
the <style> and </style> tags in the css file, or put them
in separate files and use --include-in-header to include
them all in the right order.)  ALternatively you could use
a custom template with

    <style>
    $mycss$
    </style>

and fill the variable with

    pandoc --template mytemplate.html -Vmycss="$(cat mystyles.css)"

Also see the manual under --self-contained:

> Elements with the attribute `data-external="1"` will be
> left alone; the documents they link to will not be
> incorporated in the document.

Though you may need the dev version of pandoc for this feature.

I have to say that including only local resources would be nice for me too, 
and here I mean both images and css.

Is there any way to do this in the YAML or does it have to be a command 
switch? (I suspect not.)

Does this work for any output format then and not just ePub?

Thanks John.

Yes, -H works - that's the workaround I use at the moment. I looked for the 
"data-external" attribute in the man page (using pandoc 1.19.2), 
but couldn't find it. This might be a good reason to move to the 
development version. :-)

Also, any movement about the https issue with pandoc? If I remember 
correctly, it is a problem of the underlying http library...

Thanks once more for pandoc - I love it!

Can you give me an example to reproduce this?
Also, what version of pandoc are you using?

I have the issue on Windows with files like the following one:

# Test with https image


Here a https image from w3schools:


![](https://www.w3schools.com/html/pic_mountain.jpg)

However now I try to reproduce it on macOS - and cannot: The https resource 
is downloaded properly. Here on macOS I use 1.17.1 (will upgrade soon).

Over the weekend I don't have access to the Windows machine, so I cannot 
tell you the pandoc version there. (It won't be the current one either.) I 
will report back begin of next week.

Re: Embed only local resources

[John MacFarlane]

OK, if it's Windows related, then there's likely nothing we
can do to fix it in pandoc -- one would have to talk to the
maintainers of the libraries we use for networking.

You might try getting the latest dev version from
pandoc-nightlies and testing that on Windows.
