Dear WeatherCat DIY types,
I think it likely that I'm not the only longtime Macintosh user who has concluded that Apple's attention span is getting steadily shorter. Evidence for this comes from an unlikely source: MacOS notification framework. For starters, it is difficult to get much information about simple matters like exactly how much can be displayed in the MacOS notification network. After considerable searching, I found this webpage on web notifications that indicated what were the limits of MacOS notifications.
https://help.batch.com/en/articles/4367478-what-is-the-optimal-length-for-every-web-push-notificationYou will find the information on MacOS at the bottom of the article and you will note that the MacOS notification displays the least amount of text and has no facility for anything else like graphics - something its rival systems do support.
This has become important to WeatherCat users because
build 320 of the WeatherCat 3.2.0 Beta now includes support for custom alerts being displayed as MacOS notifications. As noted in the release notes:
8. Custom alerts are now sent to the macOS notification system. Note that the alert text will be truncated by the notification system . . .
As a result, the first notifications I received looked like this:

All the useful information was truncated! So I started to rephrase everything to be as terse as possible. This is what I finally came up with:

You will find instructions on how to format the custom alert text on starting on page 153 of the current WeatherCat manual. One of the tricks I had to come up with is to display the date and time at the end of the second line of text. The date ends up being truncated but the time appears which is what I was interested in. As a result the MacOS notifications for temperature alerts (and their clearing) look now like this:

I cannot say I'm exactly happy, but at least I can live with these changes.
To make it easier to mock up a MacOS notification I cobbled together a tiny AppleScript that you can use to test out various alert text combinations. It is attached to this posting and displayed as text below.
set titleText to "Notification title"
set subtitleText to "First line of text"
set notificationText to "Second line of text"
display notification notificationText with title titleText subtitle subtitleTextTo use it, double-click on the script and then replace the text in the first 3 lines of the script with your proposed alert text (obviously, put your text between the quotation symbols.) You can click on the run triangle at the top of the AppleScript editor to see what your proposed notification looks like.
I hope this is some help in taming the MacOS notification system such that it becomes more usable to us WeatherCatters.
Cheers, Edouard
