several people told me (unprompted) that they liked my "micro dev blogging" for Bobby on here.
so fave if you want to see my failures in real time for the next one. :)
alright let's get started!
got a backend that mirrors+archives to SQLite (hence Bobby) space weather data from the NOAA. and you'll be able to self-host a mirror.
now to write a beautiful aurora dashboard in #gtk #libadwaita UI!
the NOAA space weather data does not have an API. it's a bunch of undocumented random .json files behind a CDN that sometimes partially cuts cached files.
so I wanted to have something reliable to work with first.
it's... interesting for an official government agency... ๐คจ
hitting the ground running because of all the code reuse. thanks Bobby. :)
been a while since I used a Grid (probably GTK2 days). and being able to set relative positions to other items is a lot more intuitive and less clunky than hardcoding edge numbers.
also <sub> and <sup> texts are working nicely for scientific notations! ๐
adding โจ.
almost done with the low hanging fruit. now need to add graphs over time.
best way to do that?
boom. bar charts. ๐
just using a GtkFrame and styling with CSS.
the line graph will be trickier, but thinking about generating an SVG and displaying that.
TIL about GtkLevelBar.
GtkProgressBar's lost brother from an other mother.
just set the min/max and a value. convenient!
#libadwaita has a handy .accent CSS class for labels.
using that (+bold) to highlight when measurements are good or heading in the right direction.
adding a main summary card for those not yet familiar interpreting the numbers.
I wonder if I can turn this into a widget that goes next to the weather in the shell?
adding a small inline โ ๏ธ icon and suddenly your eyes have a kind of anchor from which to explore the rest of the text.
sometimes decorations are good.
got some line graphs going using SVG and with the system accent colour.
still blurry and need to iterate on the style, but it's a start. ๐
using the .warning CSS class to highlight upcoming high Kp values. ๐จ
the threshold will be configurable in Preferences and/or based on your location.
settling on the layout. I think this will be it for the first release.
funky colours that match the wallpaper totally by accident... ๐
also added a #fediverse hashtag graph. arguably the best indicator!
ok, light theme! โ๏ธ
cards use the same colour as windows. so I'm slightly changing the base window colour to the one used in sidebars (like in Files).
GTK doesn't seem to have a .dark or .light CSS selector. so had to manually toggle a class and listen for the dark mode signal. no big deal.
had this idea of just showing country flags instead of city names.
it's less precise, but I think a lot more engaging. :)
Bruce Elrick@hbons Heh, will this cover North America?
If so, for Canada you might want to include provincial flags (e.g. ๐ด๓ ฃ๓ ก๓ ก๓ ข๓ ฟ for Alberta, or qualified flags like ๐ด๓ ฃ๓ ก๓ ก๓ ข๓ ฟ/๐จ๐ฆ for Alberta/Canada), otherwise the land area is too vast. Hell, our provinces can be rather large.
@virtuous_sloth at some point yes. :)
but as I understand it's not really possible to predict West-East occurrences... just very broadly North-South. I guess it could be based on whether the sun has set.
@hbons You are right, they are quite broad east-west, but there is some variation. Looking at this one, if you know what parts are heavily populated, some of the most populated parts of the country in the south of the east, including around 20 million people, are not in the zone while there are less-populated parts in the south of the west which are in the zone that nevertheless inclued almost 10 million people. A challenge to be sure.
@hbons I wish you good progress with your cool development!
