Sigil Qt6 and GUI plugin development changes - Page 2

odamizu,
If you had an earlier version of Doitsu's Markdown plugin installed and its prefs are not empty, then it will assume it knows the path to the cmark executable and will not run os.chmod on the binary.

The easiest approach it to temporarily rename the Markdown preferences folder once. Then fire up Markdown and it will look for the new cmark executable and properly chmod it to be executable.

You should be able to put the renamed Markdown prefs folder back or just set new preferences.

This worked for me.

I will build a universal binary for macOS and provide it to Doitsu when I am home and have access to my arm64 machine.

KevinH · 08-07-2023, 11:41 AM

Unfortunately, this same problem will exist every time this plugin is updated on macOS. And I do not think a preference setting will help. FWIW, since a chmod is cheap, in plugins I simply just use os.chmod for macOS binaries on every run. We did this in flightcrew and in AccessAide. Not sure how to detect the plugin changed when the preferences did not.

Perhaps include a new datetime value hardcoded in every plugin and check if prefs version of that value is different from current and run os.chmod if not equal.

Of course reinstalls of the same version would still fail.

The only other approach would be to run os.stat and get the st_mod bits and check if execute permissions are set and if not set them. But just setting them each time is easier which is what we ended up doing.

@Doitsu,
Okay, I figured out how to build a universal binary (arm64, x86_64) from just my x86_64 laptop statically linked for cmark-gfm

I have attached it as a zip to this post.

See cmark-gfm.zip

lipo shows this binary supports both arm64 and x86_64.

I tested the x86_64 side by install your MarkdownImport plugin, replacing the binary with the unzipped cmark-gfm, and then manually removing the MarkdownImport.json from its Preferences to force the os.chmod to be done.

It worked just fine.

I do think at some point we need to add a post plugin install interface call out to the plugin so that one time initialization can be done. I will think about adding something like that to the plugin interface for a future release.

Take care,

KevinH

Thanks! I've replaced the macOS binary in the MarkdownImport plugin .zip file with your version and attached it to first post in the MarkdownImport plugin thread.

odamizu · 08-07-2023, 03:44 PM

Thanks Doitsu! Thanks KevinH!

I downloaded the new latest MarkdownImport plugin (0.1.5.4), did the thing with the preferences folder, and all is good on Sigil 1.9.30 on macOS Ventura

ETA: I installed Sigil 2.0.0-Beta-Mc-x86_64.txz and have been playing with it, running plugins, etc. So far so good

Has anyone perhaps hit this snag?
I'm getting a PySide6 Missing from the testplugin_v020.zip, after installing PySide6:

$ pip3 install PySide6
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: PySide6 in /home/derrick/.local/lib/python3.10/site-packages (6.6.0)
Requirement already satisfied: PySide6-Addons==6.6.0 in /home/derrick/.local/lib/python3.10/site-packages (from PySide6) (6.6.0)
Requirement already satisfied: shiboken6==6.6.0 in /home/derrick/.local/lib/python3.10/site-packages (from PySide6) (6.6.0)
Requirement already satisfied: PySide6-Essentials==6.6.0 in /home/derrick/.local/lib/python3.10/site-packages (from PySide6) (6.6.0)

The specific exceptions are:

Python Package: PySide6 Missing
/usr/lib/x86_64-linux-gnu/libQt6DBus.so.6: undefined symbol: _ZN9QtPrivate23CompatPropertySafePointC1EP14QBindi ngStatusP20QUntypedPropertyData, version Qt_6

/usr/lib/x86_64-linux-gnu/libQt6DBus.so.6: undefined symbol: _ZN9QtPrivate23CompatPropertySafePointC1EP14QBindi ngStatusP20QUntypedPropertyData, version Qt_6

derrickoswald · 11-16-2023, 06:06 AM

Following the Dependencies section of https://pypi.org/project/PySide6/ doesn't seem to fix it:

LLVM_INSTALL_DIR=/opt/clang/libclang

DiapDealer · 11-16-2023, 06:39 AM

That environment variable is only relevant when building PySide6.

I've not had much experience with a Sigil plugin Python environment that includes packages installed to a user site directory instead of the system one. Can you show me what the test p!gain shows for sys.path locations? It should be some of the very first output when running the testplugin.

The fact that Debian/Ubuntu doesn't yet supply their own PySide6 packages (to be installed via apt-get) is unfortunate. Problems like yours are not likely to go away until they do.

One quick thing to try is to skip the sigil launch script in /usr/local/bin and launch sigil directly from a command prompt using:

/usr/local/lib/sigil/sigil

If Sigil starts ok, try running the test plugin again.

What did you use for an install prefix when configuring Sigil? And why? I'm a little concerned that Sigil has been installed to /opt rather than the typical /usr/local. You're changing things that really shouldn't be altered if you don't know exactly what you're doing.

I've never seen this output from Sigil's test plugin before:

Code:

Wrapped: /opt/sigil/bin/sigil

I've never seen this output from Sigil's test plugin before:

Wrapped: /opt/sigil/bin/sigil

That was just added by me to explain the two different outputs (wrapped vs raw).

The install prefix was:

Code:

-DCMAKE_INSTALL_PREFIX=/opt/sigil

The reason is, I try to put any manually installed stuff in /opt as a means of tracking and hence being able to quickly delete installations by removing a directory.

By the way, if I just remove the QTLIB_DIR definition in that wrapper script:

Code:

#QTLIB_DIR="/usr/lib/x86_64-linux-gnu"
QTLIB_DIR=""

it works correctly (at least the testplugin and a quick smoketest), so I'm good with that.
Thanks for the heads-up about the wrapper.

That (removing the QTLIB_DIR) was what I was trying to test by launching Sigil directly (without the wrapper).

Just know that if you ever rebuild/install, you'll need to diddle that wrapper again.

I may look into adding functionality (through an environment variable) that will avoid adding the QTLIB_DIR to the LD_LIBRARY_PATH in the first place. It's not need when using the system Qt, and as you've now noticed: it interferes with a PyPi installed PySide6 (which comes with its own Qt libs). Adding QT_LIBS to LD_LIBRARY_PATH was necessary when custom versions of Qt were being installed and used to build Sigil with.

Sorry about the wrapped/raw confusion. I didn't scroll down far enough to see that there were two separate outputs generated.
