This was pinned by Darren a wee while back, I think, due to some other
problem. But this kills coverage. Right now I want coverage so I can see
what needs testing with the command palette. So let's unpin with a view to
pinning back again (or solving the main problem I guess) once I'm done.
* Add a notification class and a class to hold notifications
This provides the core classes for holding information on a single
notification, and then on top of that a class for managing a collection of
notifications.
* WiP: End of day/week commit to pick up post-holiday
* Ask permission rather than forgiveness
Yes, this does go against all things Pythonic, but in this case it's likely
less costly to do the check first; moreover it works around the problem I
ran in to: https://github.com/Textualize/textual/issues/2863
* Move the handling of "I've seen this" into the toast rack
This way the interface becomes "here's a bunch of notifications, you go work
this out".
* Add a notify method to all widgets
* The removal time for a toast should be the time left
When it was per-screen, it made sense that it was the timeout; now that
we're carrying them over between screens we're going to make sure they're
only around for as long as they need to be.
* Carry notifications between screens
* Remove the test code
* Drop the borders from the toasts
Except for the title, keep that.
* Provide access to the notification timeout
* Remove the title panel from a Toast if the title is empty
* Make the Toast CSS classes "private"
Prefix with a - to reduce the chance of a clash with userspace.
* Refresh a docstring
* Stop widget leakage
The Toasts were removing themselves, but they're wrapped inside a helper
container that keeps them aligned right. So the problem was that the
alignment containers were leaking. This ensures that when a Toast goes away
it takes its parent with it.
* Make the alignment container hidden
This doesn't really make any difference, but it feels like it makes sense to
hide it if there's nothing to show -- it's purely for alignment.
* 🚚 Rename the toast container
This is about getting the toasts to align correctly (even when you do align
things, they don't really align as expected due to the way that a container
aligns the bounding box of all if its children, not the individual
children). However, I had this named after where it aligned them to; someone
using the system may wish to change that, so let's make the name more
generic.
* Improve ToastRack._toast_id
Add a docstring, and also change the format of the identity somewhat so that
it's even "more internal".
* Add some initial low-level notification testing
* Add initial testing of notifications within an application
* Add tests for notifying from the 3 main levels within the DOM
* Add a toast example to the docs and a snapshot test
This might not be the final form, but it'll do for the moment. I want to get
the snapshot test in place at least.
* Add a snapshot test for notifications persisting between screens
* Add some documentation for a Toast
This isn't going into the index, just yet. This is *technically* an internal
widget so I'm not sure how and where it makes sense to document it; if at
all. But let's get some documentation in here anyway.
* Flesh out the docstrings for the notify methods
* Add a missing docstring to the Notifications __init__ method
* Add snapshot tests for persisting notifications through mode switches
* Remove unused import
Looks like eglot/pyright tried to be "helpful" at some point and I didn't
notice.
* Correct the Toast severity level classes in the docs
Originally they weren't in the "internal" namespace, then I decided that
they should be so there's less chance of a clash with dev-space code; but I
forgot to reflect this in the docs.
This fixes that.
* Make the removal of notifications/toasts a two way thing
The addition of the ability to dismiss a toast by clicking on it had a flaw:
the notification->toast code had been written with things being one way. The
expiration of notifications happened in the notification handler, and the
expiration of Toasts was done in the Toast system, on purpose (notifications
might end up being routed via elsewhere so this needs to be done).
But... this meant that hand-removed Toasts kept coming back from the dead
when a new notification was raised iff the hand-removed ones hadn't yet
expired.
So here I add the ability the remove a notification from the notification
collection.
* Remove an unhelpful comment
Sort of a hangover from what was initially looking like it was going to be a
longer body of code. It doesn't really need explaining any more.
* Add in support to the notification collection
* Change the toast rack adder to be a general "show" method
This turns the method into one that further aids making the connection
between the notifications and the toasts two way. Now it makes sense that if
there are toasts for notifications that no longer exist, they also get
removed.
This makes it easier to add all sorts of clear options later on.
* Add a method to clear notifications
* Add an App method for clearing all existing notifications
* Add a missing docstring to _refresh_notifications
* Return the notification from the notify methods
It can be seen as, and used as, a handle of sorts (see unnotify); so return
it so people can use it.
* Add some more notifications unit testing
* Add some more app-level notification unit testing
* Style tweaks
* docs
* added notifications
* snapshots
