I tried out the patch, and my comments are in the MWE below.
Is this saying "subtract the value of 'html_link_root' from the Org link
to make its URL"?
If so, I think this would not be general enough to help some cases. For
example, with Nikola+orgmode and with Nikola's "pretty URLs" option the
relative location between either the Org source or its generated HTML
and an image that they both link will differ.
Good point. I overlooked that.
I have this MWE that explains the "would like to have" vs "what this patch gives us":
#+TITLE: ox-html root dir
An =image.png= exists as =/tmp/site/static/images/image.png=.
* This is how the image links should have worked with the link root already specified
- The =HTML_LINK_ROOT= should to appended to the front of the above link if that
concatenated path is a valid one.
- Would also like =C-x C-o=, inline image display, etc. to work.
- So a thought.. should the link root specification be made exporter agnostic?
* This works after adding support for ="" ..
- The link path becomes too long.
- Need to hard-code the full path to the site/blog root directory before each of
Nikola source wants this layout:
The Org source generates to HTML which will be found at this URL path:
The organization for Hugo posts is something similar. So hopefully we can have a solution that works for such blogging platforms in general.
In comparsion, the hugo paths would be:
So, right now, either the Org link to the image must be written to be
invalid (for Org):
Yeah, this is a problem and can probably be fixed if a support for something like "#+LINK_ROOT" can be made in Org and not specific to an exporter backend.
Or, some mechanism needs to turn the valid Org link:
<img src="" ...>
<img src="" ...>
I guess I could use html_link_root set to "/path/to/my/nikola" but then
my Org source loses portability.
I think better would be able to explicitly state the desired URL path
for the HTML <img> like:
As I mention in my MWE, I am actually looking for a solution so that we do not need to specify the "mysiteroot" for each link.. may be just one as a "#+LINK_ROOT".
