Contrib missing from (Cygwin) Emacs

Contrib missing from (Cygwin) Emacs

[Sebastien Vauban]

Hello,

When trying to publish my Web site pages with the most recent Cygwin Emacs[1], I
get the following error:

It seems that `org-ditaa' and `org-exp-blocks' both expect to find an
"../contrib" directory. Such is not bundled with Emacs. Isn't the assumption
wrong, then or should `contrib' be bundled as well?

I don't know how Cygwin builds the Emacs package...

If this is a problem in Cygwin, it's a miracle (?) no Org user
reported it before!

I don't know how to fix this, things are fine in Org >=7.9.

I don't think it's related to Cygwin per se. AFAIK:

- `contrib' is not bundled within Emacs, while

- `org-ditaa' and `org-exp-blocks' both expect that directory along where
  org.el resides

in the current Org version...

Just grep for "../contrib":

./ob-ditaa.el:55:				   "../contrib"
./org-exp-blocks.el:252:				   "../contrib"

I guess the (relative) hardcoding should be avoided.

Best regards,

Hi Sébastien,

yes, the default `org-ditaa-jar-path' value points
to the contrib/ directory, but a wrong value for this
variable does prevent publishing a web page -- unless
you want to publish ditaa shunk without setting the
`org-ditaa-jar-path' correctly.

Is it what you did?

No they don't, this is only used as a fallback if they can't find the
expected files elsewhere.  You need to configure where they should find
the JAR files.

For my Org-mode in Cygwin I followed the instructions at

http://orgmode.org/worg/org-faq.html#keeping-current-with-Org-mode-development

This not allows you to have "bleeding edge" org-mode, but the contrib 
directory is now present in my Cygwin; I do  not believe that the Org 
contrib directory is in the Cygwin Emacs.

Nope. I don't use DITAA in my Web pages at all.

When looking more carefully at the backtrace:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (error "Can't find library org")
  signal(error ("Can't find library org"))
  error("Can't find library %s" "org")

  require(org-exp-blocks)
  byte-code("\300\301!\210\300\302!\210\300\303!\210\300\304!\210\300\305!\210\300\306!\207" [require org org-macs org-agenda org-exp-blocks ob-exp org-src] 2)

  require(org-publish)
--8<---------------cut here---------------end--------------->8---

it seems that (in the latest Cygwin Emacs, that is Emacs bundled with Org-mode
version 7.8.11):

1. `org-publish' calls `org-exp' (still true as of today)
2. `org-exp' calls `org-exp-blocks' (not true anymore)
3. `org-exp-blocks' needs, somehow, a right value for DITAA.

Wait, wait, wait...

When reading the backtrace even more carefully, this 3rd observation is not
what's said by the error message: "../contrib" is not (I guess Achim is right)
the problem here, but the fact that `find-library-name' fails to find "org".

So, the problem comes down to the fact that the following...

#+begin_src emacs-lisp
  (require 'find-func)
  (find-library-name "org")
#+end_src

... does fail with the latest Cygwin [1]:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (error "Can't find library org")
  signal(error ("Can't find library org"))
  error("Can't find library %s" "org")
  find-library-name("org")
--8<---------------cut here---------------end--------------->8---

OTOH, the following does work:

#+begin_src emacs-lisp
  (message "%s" (locate-library "org"))
#+end_src

and returns:

--8<---------------cut here---------------start------------->8---
/usr/share/emacs/24.2/lisp/org/org.elc
--8<---------------cut here---------------end--------------->8---

I'm not sure to understand the (subtle?) difference between
`find-library-name' and `locate-library'...

IOW, using `locate-library' (if equivalent) in `org-exp-blocks' would (seem
to) be a workaround to this problem. But...?

  Seb

Please report the problem to Cygwin people.  They can either 
upgrade to a more recent version of Emacs, or try to sort out
the problem with (find-library-name "org").  I cannot do
anything from here, `find-library-name' is not in latest Org.

I remember... that bug has since been fixed in Org.  As a workaround,
install the emacs-el package which contains the source files to prevent
this from happening with that particular version of Emacs/Org on Cygwin.

Exactly what you said... Perfectly seen!

Though, I'm not sure to understand why that solves the issue... except if the
emacs-el package gets updated more often that Emacs, then?

Cygwin's emacs is the latest upstream release.  The problem is that the 
current Org distributed with emacs requires the presence of elisp source 
files, which are not installed by default on Cygwin.  Cygwin users of 
the current Org have to install the emacs-el package to get the elisp 
source files.

The original implementation of find-func looked explicitly for org.el,
which wasn't ever working with either compressed or not-installed source
files.

Sorry, what I meant was: the original compatibility macro for
find-library-name (since that function is not available in all versions
of Emacs).  It has since been replaced with an implementation that uses
a function that is available in all versions of Emacs and uses the same
logic as load-library to find "org" so it will find org.elc, org.el.gz
etc.pp.
