Version 564

more macOS work

• thanks to a user, we have more macOS features:
• macOS users get a new shortcut action, default Space, that uses Quick Look to preview a thumbnail like you can in Finder. all existing users will get the new shortcut!
• the hydrus .app now has the version number in Get Info
• macOS users who run from source should rebuild their venvs this week! if you don't, then trying this new Quick Look feature will just give you an error notification

new fuzzy operator math in system predicates

• the system predicates for width, height, num_notes, num_words, num_urls, num_frames, duration, and framerate now support two different kinds of approximate equals, ≈: absolute (±x), and percentage (±x%). previously, the ≈ secretly just did ±15% in all cases (issue #1468)
• all system:framerate=x searches are now converted to ±5%, which is what they were behind the scenes. != framerate stuff is no longer supported, so if you happened to use it, it is now converted to < just as a valid fallback
• system:duration gets the same thing, ±5%. it wasn't doing this behind the scenes before, but it should have been!
• system:duration also now allows hours and minutes input, if you need longer!
• for now, the parsing system is not updated to specify the % or absolute ± values. it will remain the same as the old system, with ±15% as the default for a ~= input
• there's still a little borked logic in these combined types. if you search < 3 URLs, that will return files with 0 URLs, and same for num_notes, but if you search < 200px width or any of the others I changed this week, that won't return a PDF that has no width (although it will return a damaged file that reports 0 width specifically). I am going to think about this, since there isn't an easy one-size-fits-all-solution to marry what is technically correct with what is actually convenient. I'll probably add a checkbox that says whether to include 'Null' values or not and default that True/False depending on the situation; let me know what you think!

misc

• I have taken out Space as the default for archive/delete filter 'keep' and duplicate filter 'this is better, delete other'. Space is now exclusively, by default, media pause/play. I am going to set this to existing users too, deleting/overwriting what Space does for you, if you are still set to the defaults
• integer percentages are now rendered without the trailing .0. 15%, not 15.0%
• when you 'open externally', 'open in web browser', or 'open path' from a thumbnail, the preview viewer now pauses rather than clears completely
• fixed the edit shortcut panel ALWAYS showing the new (home/end/left/right/to focus) dropdown for thumbnail dropdown, arrgh
• I fixed a stupid typo that was breaking file repository file deletes
• help->about now shows the Qt platformName
• added a note about bad Wayland support to the Linux 'installing' help document
• the guy who wrote the Fixing_Hydrus_Random_Crashes_Under_Linux document has updated it with new information, particularly related to running hydrus fast using virtual memory on small, underpowered computers

client api

• thanks to a user, the undocumented API call that returns info on importer pages now includes the sha256 file hash in each import object Object
• although it is a tiny change, let's nonetheless update the Client API version to 61

boring predicate overhaul work

• updated the NumberTest object to hold specific percentage and absolute ± values
• updated the NumberTest object to render itself to any number format, for instance pixels vs kilobytes vs a time delta
• updated the Predicate object for system preds width, height, num_notes, num_words, num_urls, num_frames, duration, and framerate to store their operator and value as a NumberTest, and updated predicate string rendering, parsing, editing, database-level predicate handling
• wrote new widgets to edit NumberTests of various sorts and spammed them to these (operator, value) system predicate UI panels. we are finally clearing out some 8+-year-old jank here
• rewrote the num_notes database search logic to use NumberTests
• the system preds for height, width, and framerate now say 'has x' and 'no x' when set to >0 or =0, although what these really mean is not perfectly defined
