Re: [O] BUG: the builtin LaTeX/P DF exporter mislabels source blocks as figures.

[John Kitchin]

This works as expected in LaTeX for me with org-ref (you could probably use raw latex if you wanted):

#+caption: The first source block. label:src-1

#+BEGIN_SRC ipython

print('Hello world')

#+END_SRC

Later we refer to the code in Listing ref:src-1 or ref:src-2. That is different than Figure ref:fig-1.

#+caption: My figure. label:fig-1

[[./test.png]]

#+caption: The first source block. label:src-2

#+BEGIN_SRC ipython

print('Hello world')

#+END_SRC

The downside is that for html the src-block links are not numbered. I don't know how easy that would be to fix in the export functions.

Dunno. Maybe \captionof{listing} ? Or let minted do its thing ? Anyway,
in most cases, the code excerpts will be too long for a float ; the
idea is to send them (unfloated but labeled/captioned) in an appendix
and point to them via a link.

[ BTW : we should stop suggesting to use listings, which is problematic
for anything not strictly ASCII, bloody likely to occur at least on a
comment/prompt for most of mankind... Listingsutf8 is but a patch
working only for (a subset of) European languages. Arabic, Hebrew,
Asian languages : nope. Minted in (xe|lua)tex is probably more usable
(but needs --shell-escape, which can justifiably frowned upon... ].

Attached.

But please coordinate with Bastien, who asked me just yesterday to
avoid posting fat attachments to a message going to a lot of people.
Which I did (to no avail : the "heavy" mail went through anyway. Go
figure.... ;-).

You're welcome ;-). Thank YOU for considering scratching *MY* itch...
