Hello Johnny,

 Many thanks for all the help! I have now figured out how to use maxima
 from org-mode source blocks and display the results as pretty printed
 equations online. To remember, I made a small summarising example file,
 attached below for posteriority.

This is very useful, thanks a lot. A couple comments and questions on
your example file (which would be a nice addition to worg).

It would be useful to know more about maxima and how to enable it with
babel (a link to existing documentation, if there is any, would be
great).

In my setup, the previewing latex fragment keybinding is C-c C-x C-l,
not C-c C-x C-x.

I tried previewing the fragment, but I got the error:

,
| Failed to create dvi file from 
/var/folders/68/fvntfrw92y50gkk_67rkhsfwgn/T/orgtex16220cbr.tex
`

Looking at the tex file and the log file, it seems that the tex files is
to be processed by xelatex, but the command called seems to be pdfTeX. I
probably have something misconfigured, but I don't know what it is. Any
suggestion?

Finally, and it's a nitpick: breaking lines in the middle of (info ...)
links prevents following them using C-x C-e.

Thanks again,

Alan

There is actually already some maxima documentation on worg that got me
started as I was unsure if maxima is supported at all, I have added the
link in the summary. It would probably be good to merge to worg, but I
have no access to it and not time right now to learn how it works. Feel
free to copy paste whatever is useful to amend it though.

Thanks for the pointer, I have included some more resources I used.

Sorry, that was a typo!

Are you sure you have 'dvipng' installed as mentioned in the manual?

I have dvipng 1.14 that comes with texlive 2013-3 in F20 which seems to
work fine.

 Finally, and it's a nitpick: breaking lines in the middle of (info ...)
 links prevents following them using C-x C-e.

Actually, I never used these sort of links myself, thanks for pointing
out how this is done! :) I moved all infolinks to footnotes to avoid the
line breaks.

All the best,

Just a clarification: you cannot break the *string* argument but
newlines in other places are fine:

  (info
 (org) The Spreadsheet)

works fine, but

  (info
 (org) The 
Spreadsheet)

does not: the second string is not the same as the first one, since it
includes a newline. OTOH, you can escape the newline:

  (info
 (org) The \
Spreadsheet)

works fine.

The point is that all of this follows from the properties of
strings. Just go to the *scratch* buffer and evaluate some
expressions:

(string-equal a b a \
b)
t

(string-equal a b a 
b)
nil

I added this to ob-doc-maxima. It might require some editing.

 [... how to use maxima code from org-mode and display results inline

 You would switch from :results latex to :results raw, in which case
 the latex will be inserted directly into the Org-mode buffer, and
 org-mode's existing pretty display functionality may be used to view the
 equations inline and should work for export to HTML as well.

 Alternately, if you really want to get fancy you could use noweb
 expansion (see the manual) to insert the results of the imaxima code
 block into a latex code block, and then use the existing latex code
 block functionality to convert the imaxima output to images of different
 types depending on the export target [1].

 Thanks, this does answer my initial question and works good enough to

 Even better would be if it's possible to mimic imaxima behaviour which
 is (I think) to directly process the resulting latex code and
 (temporarily?) store it as an image to display the pretty-printed
 equations directly inline in the org-buffer (which will make it export
 as html better I guess as the latex output doesn't seem to be recognised
 when exporting to html).
