When hot reloading config with a new font, shaper cache data needs to be
invalidated and the font grid needs to be rebuilt. This change just
makes that happen on all config reloads since it's a rare action so it's
not a performance concern.
Allows for high dpi displays to get odd numbered pixel sizes, for
example, 13.5pt @ 2px/pt for 27px font. This implementation performs
all the sizing calculations with f32, rounding to the nearest pixel
size when it comes to rendering. In the future this can be enhanced
by adding fractional scaling to support fractional pixel sizes.
Now that we're padding the cells with blanks if we have shaped ligatures
we don't actually know the exact count based on the CoreText APIs, so we
should just dynamically add.
bash reads HISTFILE at startup to locate its history file, but this is
apparently too early for it to be able to expand home-relative paths. We
now manually expand the full path and add that to the environment.
This will allow for unlimited glyphs per row, eliminating the issue run in to with multi-substitution glyphs and combining characters which can result in more glyphs in a row than there are columns.
Previous version prevented multiple glyphs from belonging to the same coordinate, which broke quite a few things. This implementation fixes that (and may be more efficient too). Needs clean-up.
I introduced screen dirty flags fairly late, and never reset them. As a
result, dirty tracking basically gets disabled as soon as selection
changes in any form. This happens frequently because _unsetting_
selection also resets selection which happens for various events.
This change adds automatic bash shell detection and integration.
Unlike our other shell integrations, bash doesn't provide a built-in
mechanism for injecting our ghostty.bash script into the new shell
environment.
Instead, we start bash in POSIX mode and use the ENV environment
variable to load our integration script, and the rest of the bash
startup sequence becomes the responsibility of our script to emulate
(along with disabling POSIX mode).
