I tried to replace the biography SMP panel with a JSpliter 4.0.3, it load well and seems to work but when I tried to import the json file with the exported configuration I get and error window pop-up

Better native inside the component I think...

regor was well aware of me adding this even if no one else noticed.

Bugfixes:

Make OnProcessLocationsNotify_InsertHandles use GUID, not playlistIndex.
https://github.com/marc2k3/foo_spider_monkey_panel/commit/67433164b1cdac8aec84048a7773a92c073a118c
Fixes: https://github.com/TheQwertiest/foo_spider_monkey_panel/issues/197

utils.Glob working with ';' in folder names. ( I see this requires a lot of changes with extra helpers, an easy workaround can be done directly on JS so it is not really essential)

Improvements:

window.IsDark
https://github.com/marc2k3/foo_spider_monkey_panel/commit/b93e0a3ef9f80dcb3cf74d98c4c8fbb4cad090aa
Fixes: automatic dark themes support in scripts

fb.AddLocationsAsync(locations) and on_locations_added
https://github.com/marc2k3/foo_spider_monkey_panel/commit/75706cd7ebe232899013b39a737e8f252be961de
Fixes: playlist managers/scripts may load playlists internally as handle lists without showing the playlist on UI

fb.ShowPictureViewer(image_path)
https://github.com/marc2k3/foo_spider_monkey_panel/commit/727a298b58d4944e00cc8660148067a587a1fbfc
Fixes: Biography could open directly any art using the built-in viewer instead of a CMD call to windows image viewer.

FbMetadbHandleList.SaveAs
https://github.com/marc2k3/foo_spider_monkey_panel/commit/75706cd7ebe232899013b39a737e8f252be961de
Fixes: Library tree could save facets cache playlists internally instead of cluttering the UI with a cache playlist. Playlist managers could fully support .fpl playlists.

utils.GetClipboardText / utils.SetClipboardText
https://github.com/marc2k3/foo_spider_monkey_panel/commit/caf036c507d2974e00763381fea3d13a3bcabaf6
Fixes: Scripts could use clipboard without using ActiveX objects or requiring Internet explorer to be installed.

utils.DownloadFileAsync(url, path) and on_download_file_done
https://github.com/marc2k3/foo_spider_monkey_panel/commit/f4cacf337acd3fc40247ef619b84a237def6508d
Fixes: Scripts like biography could download art/biography without using ActiveX objects which are known to be problematic.

When checking that, please differentiate between graphic rendering and actually running the script. There are legitimate reasons to have a panel running even if it's hidden or not visible, so processing should be handled by the script itself according to callbacks.

In SMP this is done checking window.IsVisible for ex. which can be used to halt processing if desired.

For ex. if I have a lyrics panel, the lyrics should be retrieved no matter if it's hidden or not... drawing the lyrics only when the panel is visible. Undesirable behavior would be delaying the actual lyric retrieval until the panel is visible. There are tons of examples like that related to playback, tagging, etc.

I get it and BTW, does the ESR version of this same JavaScript engine as on Firefox mean ones that support Windows 7?

You can not use 4.0.x versions on Win7, that last Spider Monkey JS Engine which is from Mozilla/Firefox
that supports Win7 is 102.0esr:
https://www.mozilla.org/en-US/firefox/102.0esr/system-requirements/

Version 4.0.x uses v128.0 and Win10 is the minimum requirement:

BTW, don't expect fb.GetAudioChunk() function being added into JSplitter sooner, so I have to wait more for LUFS bars visualization (if you assume that @Crossover have left the forum) anyway or is it (foo_uie_webview)?

Wait for the release of my new plugin I have developed, it is all you need. It has LUFS, RMS, PSR, PLR, DR etc... and also raw audio samples.
I will release it very soon!

-TT

I would prefer if these statements are measured in some way (not saying you are the one who has to do it ). I even created a framework for this:
https://regorxxx.github.io/foobar2000-Framework-SMP.github.io/scripts/profiler-smp/

So it's actually possible to test specific functions (and even automate testing) with it, and comparing the reports for different versions we would really see if that's the case or not.

As the topic starter, you could post the current versions in the header and declare the 4.x branch temporarily unstable, since the topic already exists, why create a new one.

I think describing the 4.x versions as "temporarily unstable"

actually it also feels faster than 3.7.1

I may have been a bit loud and harsh about the price of progress, but you should understand me too. I don't create commercial software, I don't have a personal site to publish it on, and I don't take much responsibility for what I do. I just develop a plugin in my spare time and post the results of my work so people can find it useful or not. What can I say, this thread doesn't even belong to me, I'm just here as a contributor who posts new versions for you to try and give feedback.

Ok, the next time a bug is found the version will be called 4.0.x-beta
