html export

html export

Aloha all,

Org-mode html export recently began to format links improperly for me  
in projects that have been stable for some time and working properly.

I now get <p>img src="file:r/filename.png" alt="file:r/filename.png" / 
 ></p>

This isn't a bug report.  I've been having lots of problems publishing  
formerly stable projects, some of which I believe are due to changes  
in org-mode while others appear to stem from my setup.

I haven't investigated this one yet, but it would help me to know if  
others are seeing similar behavior when publishing to html.

All the best,
Tom

This i a bug introduced by a recent patch to factorize link creation  
in html export into a separate function.  We are still ironing out the  
small problems this patch created.  If this i a critical issue, switch  
back to an older verion for the time being.  I believe Sebastian Rose  
is now looking at the problem...

I just saw my patch was applied yesterday. For the bug is fixed, but
there might be corner cases I overlooked.

Thomas, does the current head not work for you?
If not, could you make up a little example for testing?

html export

[Thomas S. Dye]

Aloha all,

Exporting this small file to html here doesn't put a caption on the  
figure.

* No caption

#+CAPTION: Histogram of adze weights on a logarithmic scale
#+LABEL: fig:wt-log

[[file:~/Public/projects/903_adzes/r/sr-nb-scatter.png]]

Does anyone else see this?

All of a sudden, I'm having the devil's own time with html export.  I  
made small changes to a large export project file and was surprised  
when none of the links were exported.  The project has been exporting  
perfectly for months now.

All the best,
Tom

Try removing the empty line between the #+LABEL:... line and the
[[file:... line, that worked for me.  or rather the following worked for
me

--8<---------------cut here---------------start------------->8---
* No caption

#+CAPTION: Histogram of adze weights on a logarithmic scale
#+LABEL: fig:wt-log
[[file:graph.png]]

--8<---------------cut here---------------end--------------->8---

also, if the file doesn't exist, then neither the file, nor the label or
caption will export.

I agree it seems that the html export has been a little bit less stable
as of late.

I can't get it to work with or without the empty line:

Org-mode version 6.36trans (release_6.36.264.g74d3)

Be that as it may, I compared the html export code with the latex export
code and it seems to me that the caption is calculated too late in the
html code: it's done in org-export-html-format-image by looking for the
org-caption text property on its ``src'' argument, but afaict, the argument
is just a string - no text properties.

I tried the following patch, which makes the html caption handling look
a bit more like what the latex exporter does, and it seems to work in
this case, but I have not tested it any further.

Thanks,
Nick

Removing the blank line doesn't work for me either.

Org-mode version 6.36trans (release_6.36.291.gaf90f)

Ah, I'm finally able to reproduce the problem in my larger file.  Here  
is an example:

* No results exported

#+srcname: problem
#+begin_src R
   b <- 4
#+end_src

#+results: problem
[[file:~/Public/projects/903_adzes/r/sr-nb-scatter.png]]

The key is that srcname: and results: have the same name.  Changing  
the results: name works.

* Results exported

#+srcname: problem
#+begin_src R
   b <- 4
#+end_src

#+results: problem-not
[[file:~/Public/projects/903_adzes/r/sr-nb-scatter.png]]

All the best,
Tom

Hmm, I just tried the above again using the HEAD (same org-version
output as you have above) of the org-mode git repository and a minimal
emacs config, and it *is* working for me, so maybe your problems will be
resolved with an update of org-mode, or maybe they're due to something
in your config?

Yes, the key with the above is that babel by default only exports the
code of a code block, which means that if there are results in the
buffer they will be removed on export.  If you want both the code and
the results to be exported then change

  #+srcname: problem
  #+begin_src R
    b <- 4
  #+end_src

to

  #+srcname: problem
  #+begin_src R :exports both
    b <- 4
  #+end_src

I think the difference between Eric's experiment and Tom's is the
filename of the image - Eric uses a relative pathname, whereas Tom uses
an absolute one:

,----
| 
| * No caption
| 
| #+CAPTION: Histogram of adze weights on a logarithmic scale
| #+LABEL: fig:wt-log
| [[file:Pic1.png]]
`----

produces a caption, but

,----
| 
| * No caption
| 
| #+CAPTION: Histogram of adze weights on a logarithmic scale
| #+LABEL: fig:wt-log
| [[file:~/Desktop/Pic1.png]]
`----

does not.

Also, the alignment of the image changes in the two cases, which leads
me to believe that one is treated as a display and the other as an
inline image.

I didn't pay close attention when the default behavior changed.   
Adding #+property: exports both gets me back where I was before.

Also, following on Nick's message, the captions exported properly to  
html with absolute paths in the links and with lots of space between  
the caption and link.  Here's an example that exported properly:

#+CAPTION: Pairwise comparison of six metric variables
#+LABEL: fig:pairwise

#+srcname: pairs
#+begin_src R :results output :var x=whole-adzes :file r/adze_pairs.png
   whole.adze.metric <- x[,c(5,12,15,16,17,18)]
   names(whole.adze.metric) <-  
c("wt","len","edge","front","back","thick")
   pairs(whole.adze.metric)
#+end_src

#+results: pairs
[[file:r/adze_pairs.png]]

Thanks for your help.

Tom
