Hi,

When the environment variable "DISPLAY" is invalid, exporting plantuml block in org will got error message:
Exception in thread "main" java.awt.AWTError: Can't connect to X11 window server using 'localhost:11.0' as the value of the DISPLAY variable.
    at sun.awt.X11GraphicsEnvironment.initDisplay(Native Method)
...
To reproduce this issue, install the plantuml.jar and make sure it work inside org-mode.
Then open `/tmp/testing.org` and  input follow plantuml code and eval-expression `(progn (setenv "DISPLAY" "localhost:90")(org-html-export-to-html))`.
The root cause is org-mord execute the plantuml.jar in command line without headless parameter, then plantuml will try read the DISPLAY, it's unnecessary.
(For standalone plantuml, `org-plantuml-executable-args` has default value '-headless' to avoid reading DISPLAY).

Please help review the patch. Thanks.

Best Regards
Lin

Hi Bastien,

Okay, waiting a month is no problem for me, I'll give org version info in future patches.

The patch is for org version:
Org mode version 9.5 (release_9.5-46-gb71474 @ ~/.root/share/emacs/28.0.60/lisp/org/)

And the reproduce steps are edit /tmp/testing.org and eval-expression 
(progn (setenv "DISPLAY" "localhost:90")(org-html-export-to-html))

# testing.org
#+BEGIN_SRC plantuml :cmdline -charset UTF-8 :file testing.png
  @startuml
  a -> b: testing
  @enduml
#+END_SRC


Thanks.

Hi Sun,

Thanks for your patience. This looks quite straight-forward. I don't use
or have plantuml so I'm in a poor position to test.

However, I can use google, and it seems that -Djava.awt.headless=true
just uses Java for some graphics operations which are normally delegated
to the system graphics stack.

This seems rather safe to me, and so I'd be inclined to take your word
that this is a beneficial change and merge the patch.

All the best,
Timothy

Hi Sun,

Thanks for not forgetting about this. As I commented before, I this looks
sensible enough to apply, and so I’ve just pushed it as f9dcc3d with a tweaked
commit message.

You’ve also been added to the list of TINYCHANGE contributors on
<https://orgmode.org/worg/contributors.html>. If you submit more than 20
cumulative lines of non-trivial code, you’ll need to get FSF assignment.

Thanks for sharing the issue and making a patch for it 🙂 hopefully we’ll see
you around in the future.

All the best,
Timothy

Could you, please, clarify why -headless in `org-plantuml-args' is not 
enough and -Djava.awt.headless=true should be added despite it looks 
redundant. Another question is why this option should be applied to jar 
but not to plantuml launcher script. The commit dropping this option has 
a link to discussion whether this argument is necessary and hard coded 
in such way.

I am unable to reproduce the original error on latest main.
Could you please provide a reproducer when the proposed patch is
actually useful?

Best,

Hi lhor,

You're totally right, the commit b5f0efc had appended the `-headless`
to the jar parameter list. Here is the comment:
> *** =org-plantump-executable-args= is renamed and applies to jar as well
The original issue does not exist now.  Please ignore the previous patch.

Thank you so much.

Hi,
The function `org-babel-execute-src-block' will emit an error message
if the language is not loaded.

Before the error message, the patch will give a try to load the
associated babel language.

Why does the language exist in the `lang org-babel-load-languages' but
not be loaded?
Because the `org-babel-load-languages' are defined as a customer
variable with  :set 'org-babel-do-load-languages,  the ":set" function
can only be triggered with function `custom-set-variables`.
While setq/cl-pushnew `org-babel-load-languages' won't trigger the
`:set' function, then the error message will be displayed if I run the
code in the org file.

Please help review that patch. Thanks. Regards

I think this patch slightly modifies the logic of the error.

--8<---------------cut here---------------start------------->8---
 	    (unless (fboundp cmd)
-	      (error "No org-babel-execute function for %s!" lang))
+              (if (alist-get lang org-babel-load-languages)
+                  (require (intern (concat "ob-" lang)))
+                (error "No org-babel-execute function for %s!" lang)))
--8<---------------cut here---------------end--------------->8---

You are saying, that when (fboundp cmd) returns nil, and when (alist-get
...) returns non-nil, then perform the `require', and assume this
function is now available.

Instead of that, I think you should have some sort of conditional in the
`unless' condition.  Something like:

--8<---------------cut here---------------start------------->8---
(unless (or (fboundp cmd)
            (ignore (and (alist-get lang org-babel-load-languages)
                         (require (intern (concat "ob-" lang)))))
            (fboundp cmd))
  (error "... %s" lang))
--8<---------------cut here---------------end--------------->8---

This preserves the logic of the message: when we cannot get
"org-babel-execute" immediately, we then try to require the module and
try again.  Then, we check the function again and conclude that the
org-babel-execute function is not found for this language.

Thoughts?

If we want to solve the problem of setting `org-babel-load-languages'
outside `defcustom', we should also consider unloading and other places
that use `fboundp' to check if babel backend is loaded. IMHO, the
cleanest way will be using `add-variable-watcher'.

Hi Ihor,
The "add-variable-watcher" may not be able to deal with the
local/global variable `org-babel-load-languages' correctly.

The logic in the patch will follow the function
`org-babel-do-load-languages' to load the ob-LANG without capturing
the error.
I changed the patch to follow your comments.
Please review the new patch I attached. Thanks.

Hi Ihor,

Thanks for the comment.
If we switch to the `add-variable-watcher', it seems we'll load the
ob-LANG in the callback immediately.
The previous change can lazyly load the babel languages until the user
tries to evaluate the source block.

Is there any advantage doing the loading lazily?
I can only see disadvantages:

1. `setopt' already triggers loading when variable is set. It is just
   `setq', often used in place of `setopt', that does not trigger
   loading/unloading.
2. Lazy loading like you proposed will have to be added in a number of
   places, not just when executing src block: `org-edit-special',
   `org-src-associate-babel-session', `org-edit-src-code',
   `pcomplete/org-mode/block-option/src', org-lint,
   `org-babel-tangle-single-block', `org-babel-exp-src-block',
   `org-babel-exp-results', and others.
3. We will also have to monitor newly added babel functions to take care
   about lazy loading. Not to mention third-party code.

Admittedly, (2) can be solved by abstracting babel backend queries to
API. (I have a WIP code doing exactly this). However, I still see no
good reason to make `setq' different from what `setopt' does now.
Most people treat them interchangeably and then get surprised by the
differences.

Speaking of which, since we now (or are about to?) depend on compat, we
can just do (require 'compat) and forget that `setopt' is an Emacs 29
addition.

No. Compat does not support and does not plan to support `setopt' (see
https://elpa.gnu.org/packages/doc/compat.html#Limitations).
And it is not us who needs to use `setopt', but users.
We just have to deal with de facto situation with users using `setq'
mindlessly.

Makes sense.  So, does that mean nothing should be changed, except for
maybe some additions to documentation mentioning that the users should
avoid using `setq' to set customizable variables, and instead use
`setopt' if >= 29, or [some function in cus-edit.el which I don't
recall] otherwise?

Not really. It is a common problem that users keep using `setq' instead
of `setopt', customize interface, or `custom-set-variables'.

Lin Sun's solution is one approach to deal with this problem for
`org-babel-load-languages', but only partial, as I outlined.
I'd prefer to use either `add-variable-watcher' or oc.el-like API with
`org-cite-try-load-processor' being called when babel backend
information is requested.

Will you still be interested to improve the patch covering all other
cases in Org code where babel backend is used? Or using
`add-variable-watcher'?

Hi Ihor,

I use the `setopt` in my dot-emacs now, and won't make code changes.
Please feel free to close this ticket, and any code change to enhance
the discussed issue is welcome. Thanks
