PDF export seems broken

Seems to be related to this: https://github.com/vilcans/screenplain/issues/53

[AndreaMonzini]

Hello, there is a discussion to integrate the libharulibrary http://libharu.org/ in Blender:

https://lists.blender.org/pipermail/bf-committers/2020-December/050808.html

https://developer.blender.org/T83192

Maybe it could be useful for Blender_Screenwriter PDF export too ;

[tin2tin]

Thank you. I didn't know about that. Could be nice if they would support exporting text from the text editor too.

If you're on Linux, can you test if the various modules install successfully, by simply installing the Blender Screenwriter add-on?

[AndreaMonzini]

Yes, i just tried to install the last addon version on Blender 2.91 but i see this error :

Traceback (most recent call last):
  File "/app/blender/2.91/scripts/modules/addon_utils.py", line 351, in enable
    mod = __import__(module_name)
  File "/home/linux/.var/app/org.blender.Blender/config/blender/2.91/scripts/addons/Blender_Screenwriter-master/__init__.py", line 13, in <module>
    import bpy, subprocess, pip
ModuleNotFoundError: No module named 'pip'

pip seems installed in my system:

linux@pop-os:~$ pip -V
pip 20.1.1 from /usr/lib/python3/dist-packages/pip (python 3.8)

[tin2tin]

Ok. Could you reload load it and try again? (I updated a file)

[AndreaMonzini]

i installed pip manually with the instructions we tested in the past and it works:

'/home/linux/App/blender-2.91.0-linux64/2.91/python/bin/python3.7m' -m ensurepip
'/home/linux/App/blender-2.91.0-linux64/python/bin/python3.7m' -m pip install screenplain[PDF]

Now i try to use a clean Blender to check the addon update

[AndreaMonzini]

I tried the updated addon with Blender 2.83.9 ( and 2.90.1 ) but Blender crashed

Could you try again? (I've tried something else)

[AndreaMonzini]

Now no crash ( 2.83.9 ) but this error:

In the python console in Blender, what does it write when you enter these two separate lines?

import sys
print(sys.executable)

[AndreaMonzini]

[tin2tin]

Oh, it is not pointing to the python.exe on linux...

Is it the same on 2.91?

2.91 on Windows:

[tin2tin]

I've changed it to the previous python.exe location code(this will cause a reminder on 2.91 to update to code).

[AndreaMonzini]

2.91:

[AndreaMonzini]

python folder structure:

[tin2tin]

So how does that version install in 2.91?

(The current version on the repository is using the presumably 2.83 friendly code )

[AndreaMonzini]

Both Blender 2.83 and 2.91 seem to work now ! I used a clean download of Blender 2.91 and deleted ~home/.config/blender folders ( i plan to to more tests on this weekend )

[tin2tin]

That's great news. Thank you. Closing all of the pdf related bug reports now.
