`(invalid-read-syntax "#" 1 0)` when exporting a transcluded file

[maikol-solis]

Hi! I have this issue with org-transclusion with org-roam

Suppose you have these files

TEST1.org

:PROPERTIES:
:ID: 20220302T110131
:END:
#+TITLE: TEST1

TEST1

TEST2.org

:PROPERTIES:
:ID: 20220302T110150
:END:
#+TITLE: TEST2

#+transclude: [[id:20220302T110131][TEST1]] 

TEST2

If I run org-transclusion-mode in TEST2.org and then try to export the file to a pdf, I get this error in *Org Export Process* buffer

Debugger entered--Lisp error: (invalid-read-syntax "#" 1 0)
  read(#<buffer  *load*>)
  load-with-code-conversion("/private/var/folders/4d/qj4qr8zx1n36td0hlt0p7x_h00..." "/private/var/folders/4d/qj4qr8zx1n36td0hlt0p7x_h00..." nil t)
  command-line-1(("-l" "/var/folders/4d/qj4qr8zx1n36td0hlt0p7x_h0000gn/T/d..." "-l" "/var/folders/4d/qj4qr8zx1n36td0hlt0p7x_h0000gn/T/o..."))
  command-line()
  normal-top-level()

I tried the exporting without transcluding the first file and everything works as usual.

Thanks for the help.

How can I reproduce this issue? I have no problem exporting to a PDF file with your test files.

I wonder why these files are being used in your error message; they have nothing to do with Org-transclusion:

• "/var/folders/4d/qj4qr8zx1n36td0hlt0p7x_h0000gn/T/d..."
• "/private/var/folders/4d/qj4qr8zx1n36td0hlt0p7x_h00..."

It's weird to me also.

I could capture the org-export-process file in /private/var/folder/...

More information. I debugged org-export-latex-to-pdf using trace-function.

In my config I have (setq org-export-in-background t) which lead me to though that the problem could come from the async exporting process.

First, I ran (org-export-latex-to-pdf t) (the t activates the async parameter).

This trigger the issue and the file isn't exported.

======================================================================
1 -> (org-latex-export-to-pdf t)
1 <- org-latex-export-to-pdf: #[514 "\302!\303!\304=\205B�\305\306\300\"\216\307!\310U\2034�\305\311\"\216r\211q\210db\210\312 \210\313p!)\301

(fn P STATUS)"]

Then, I ran (org-export-latex-to-pdf nil) and all compiled perfectly.

What does org-export-stack give you?

In my case, these. I will try with emacs -Q later but I don't know if it is related to Org-transclusion...

[maikol-solis]

Yes you're right, there is something wrong with the export process as a whole. I changed the file to this

:PROPERTIES:
:ID: 20220302T110150
:END:
#+TITLE: TEST2

#+INCLUDE: "./20220302T110131-test1.org"

TEST2

And I got the same issue with the async export. :(

I checked org-stack-add-to-stack and I got this

======================================================================
1 -> (org-export-add-to-stack #<buffer *Org Export Process*<2>> nil #<process org-export-process>)
1 <- org-export-add-to-stack: ((#<buffer *Org Export Process*<2>> nil #<process org-export-process>) (#<buffer *Org Export Process*> nil #<process org-export-process>))

[maikol-solis]

Using emacs -Q and exporting asynchronously, I got this

Debugger entered--Lisp error: (wrong-type-argument stringp nil)

  funcall-interactively(eval-expression (org-latex-export-to-pdf t) nil nil 127)
  command-execute(eval-expression)

When debugging make-process I got this:

 ======================================================================
1 -> (make-process :name "org-export-process" :buffer "*Org Export Process*<6>" :command ("/Applications/Emacs.app/Contents/MacOS/Emacs" "--batch" "-Q" #1="-l" "/var/folders/4d/qj4qr8zx1n36td0hlt0p7x_h0000gn/T/doom-org-async-export1jeHlP" #1# "/var/folders/4d/qj4qr8zx1n36td0hlt0p7x_h0000gn/T/org-export-processRhsiVz"))
1 <- make-process: #<process org-export-process>

This is as far as I've gotten.

I have tried exporting to pdf with emacs -Q. Even without Org-transclusion in the buffer, I get this error when I evaluate (org-latex-export-to-pdf t). Evaluating (org-latex-export-to-pdf) produces a PDF file correctly.

Debugger entered--Lisp error: (wrong-type-argument stringp nil)

I don't use export or export in the async mode. I am not sure if I am using the async mode correctly, but as I get the error without Org-transclusion mode, I think the issue is outside Org-transclusion. I cannot look at it further.

I suggest you report this issue with Org development mailing list.

[maikol-solis]

Thanks! It looks like the async export process is broken in org-mode. At least there is not something in org-transclusion. Sorry for the noise.

[nobiot]

No problem! I also checked the temp file written for the async process to export with Org-transclusion on. It had the transcluded contents. So I guess as long as Org export works, it should work. This does not explain why it worked for you if you switch off Org-transclusion....

[maikol-solis]

Hi @nobiot. I'm searching for this bug again, and I found that apparently it has relation with polymode

https://list.orgmode.org/aw_wwlJcCuUcOWTA5vHxOQaat4W5s33Auov2jBSfrpkgCoM2JuGIUN6WNDQMfBYQL2NQog7cewykBnCPQa2ZuRr0Nc0mwyf4A_yEyYvxxZM=@protonmail.com/

[nobiot]

Okay, so you raises an issue in polymode. Thanks. I didnt see any relevant issue there after the org mailing list you referenced.

At the moment, I am afraid I cannot do anything.

Thank you for circling back :)

[maikol-solis]

No problem at all. Thanks for your patience.

Of course, the issue isn't related to org-transclusion at all, but the debug output here could be valuable if anyone wants to review it.

Best.
