new release

[dcnieho]

Hi Pascal,

I see you are preparing a new release. Would it be possible for you to update to the latest imgui release before doing so, since there is new useful API for shortcuts there? Or are you able to make more frequent releases again?

Just for discussion!

As always, thanks a lot for this great tool, i really enjoy using it :)

[pthom]

Hi Diederick,

Yes, I will emit a new release in the next weeks. I will try to update ImGui in the process.

In the mean time,you can download wheels in the actions on github: https://github.com/pthom/imgui_bundle/actions/workflows/wheels.yml
(They are compiled whenever I push new code).

Or are you able to make more frequent releases again?

I am limited by the project size limit on Pypi (10GB max). I did hit the size limit a few months ago (after which I had to remove several older releases).
I just took the time to file a project size increase request to Pypi support's team. I hope they will accept it, but it might take a while.

In the meantime, I know that I can only release about 2 or 3 more versions before I hit the limit again. So I have to reduce the frequency

[dcnieho]

Oof, i once had a request with them (for a name, not size), it took the better part of a year. Hope yours goes faster!

It specifically the 1.90.7 support for shortcuts that would be interesting to try out, so that wouldn't be in your wheels yet. I saw also that there is a breaking change in docking/viewports, by the way, hope that doesn't break your stuff

Hi Diederick,

I did update ImGui to v1.90.7. It took me about half a day because I had to update also ImGui Test Engine, and also update the generator options due to new functions being overloaded.

Concerning your other question, see 905a805 where I tentatively set the deployment target to 10.14.

Please do test this with your user and keep me informed about the result, I cannot test that on my side; and I can only look at the CI results.

[dcnieho]

Thanks for considering dropping the requirement to 10.14. I see the CI fails with the luckily informative message that std::filesystem::path was introduced in 10.15. Mind retrying with 10.15?

Thanks for the trouble!

[pthom]

I change it to 1015.
Please try it on your side . You can update your clone and push the CI should run on your side also.

[dcnieho]

Thanks! That built successfully. I have asked my student to try and install the wheel generated by your action.

[dcnieho]

The cp311 wheel installed successfully on the student's platform, but when they try to run imgui_bundle_demo, it errors:

I'm trying with 10.16 on my own fork now, will keep you updated.

[dcnieho]

This brotli decoder may not be about the deployment target (may..), also doesn't work on 10.16, same error message. I thought maybe the user doesn't have this brotli available.
However, both using
pip install brotli
and
brew install brotli
Did not resolve the import error. (Both installed the 1.1.0 version, which is also what the build script picked up according to the log)

I am now trying to use the macos-13 instead of macos-latest runner, lets see...

[dcnieho]

Note (also for myself), brotli is pulled in by freetype in hello_imgui. Pulling it in can be disabled, using FT_DISABLE_BROTLI, which is marked as "Disable support of compressed WOFF2 fonts." But this may well not be brotli specific, just the first thing that fails.

[dcnieho]

Trying to build on an earlier runner fails:

So i guess that means were stuck unless one would build all these libraries yourself. The cibuildwheel docs say:
Since delocate 0.11.0 there is added verification that the library binary dependencies match the target macOS version. This is to prevent the situation where a wheel platform tag is lower than the actual minimum macOS version required by the library. To resolve this error you need to build the library to the same macOS version as the target wheel (for example using MACOSX_DEPLOYMENT_TARGET environment variable). Alternatively, you could set MACOSX_DEPLOYMENT_TARGET in CIBW_ENVIRONMENT to correctly label the wheel as incompatible with older macOS versions.

This error may happen when you install a library using a package manager like Homebrew, which compiles the library for the macOS version of the build machine. This is not suitable for wheels, as the library will only work on the same macOS version as the build machine. You should compile the library yourself, or use a precompiled binary that matches the target macOS version.

[dcnieho]

The strange thing perhaps is that the user is on 13.4, but the compatible targets declared by python go no higher than 10.16.

[dcnieho]

Ok, this seems to be a bug in pip/packaging. See for instance here:
spinalcordtoolbox/spinalcordtoolbox#4359, or here: microsoft/onnxruntime#19371 (comment)
So the solutions are to have a new enough pip (and thereby a new enough packaging package, >=22.0), or to set the SYSTEM_VERSION_COMPAT=0 environment flag when trying to install imgui_bundle.

I have asked my user to check.

[pthom]

AFAIK, OS updates are free on Mac. Is there a compelling reason why those students cannot update their version of macOS?

[dcnieho]

I hear from MacOS users that upgrades are likely to bring new problems and compatibility issues as much as new features. So they ten to upgrade once a year, if even that (don't change a working setup). But yeah, users shouldn't need to be forced to update MacOS to be able to install imgui_bundle. If this turns out to be running into a pip/packaging bug, then I guess the solution is a small addition to the docs. Will let you know/send pull request.

[dcnieho]

Reading pip changelogs, i see that the fixed version of the packaging package still isn't vendored by latest pip, so that did nothing.

But asking the user to run
SYSTEM_VERSION_COMPAT=0 pip install --only-binary=:all: imgui_bundle
got stuff installed, and it ran! I'll send you a pull request with a doc update, if i find a nice place (and to revert the target version stuff in the build scripts)

Thanks for going down this road with me!

[pthom]

Thanks for going down this road with me!

You're welcome. I just merged you PR. Thanks a lot

[dcnieho]

Most welcome, glad we figured this out!
