scenario:
- create a long wrapping line
- tap past end of first screen line
Before this commit the cursor would be positioned not quite at the end
of the screen line but one character before. In effect there was no way
to position cursor at end of a wrapping line.
I'm not sure how this bug has lasted so long. It was introduced in
commit 8d3adfa36 back in June 2022, which was itself billed as a bugfix
for "clicking past end of screen line". But when I go back to it this
bug exists even back then. How did I miss it?! I wrote a test back then
-- and the test was wrong, has always been wrong.
- source editor always expects relative paths
- refresh mocked data
There's still one issue after this: the font size saved in the config
file is the one we use in tests. More broadly, Editor_state is
completely wrong.
Ideally I'd just not save any settings for the source editor if the
tests fail.
Scenario:
modify a test to fail in the source editor
delete any settings in the 'config' file in the save dir
start lines.love
press C-e to switch to source editor
Before this commit, this scenario led to the following events:
the C-e keypress invokes App.run_tests_and_initialize()
the failing test results in a call to error()
the call to error() is trapped by the xpcall around the event handler in love.run
handle_error runs
Current_app is 'source', so love.event.quit() is triggered
love.quit() is invoked
source.settings() is invoked
App.screen.position() is invoked, which calls the test mock
Since App.screen.move was never invoked, App.screen.position() returns nil
The 'config' file is written without values for source.x and source.y
As a result, future runs fail to open.
This is likely a corner case only I will ever run into, since I'm
careful to never commit failing unit tests. Still, I spent some time
trying to figure out the best place to fix this. Options:
* don't write config if Error_message is set
but we do want config written in this scenario:
* we hit an error, source editor opens
* we spend some time debugging and don't immediately fix the issue
* we quit, with some new files opened in various places
* hardcode source.settings() to call love.window.getPosition() rather
than App.screen.position().
drawback: weird special case
* clean up test mocks before aborting
this seems like something we always want
I'm not very sure of my choice.
This bug doesn't leave me feeling very great about my whole app.
Arguably everything I've done is bullshit hacks piled on hacks.
Perhaps the issue is:
- naked error() in LÖVE apps never invokes love.quit(), but
- an unhandled error within my handle_error invokes love.quit() (via
love.event.quit)
Perhaps LÖVE should provide a way to abort without invoking the quit
handler. There's literally no other way in LÖVE to request a quit.
scenario: run without config file, quit, run again
expected: font size remains the same on second run
Before this commit it was increasing on each run.
It turns out the font height that you pass into love.graphics.newFont()
is not the result of font:getHeight().
