Using the "subpixel quantization" option for rendering our glyph was
creating bad edge cases where we'd lose the bottom or left row / column
of pixels in a glyph sometimes. I investigated the exact effect of this
option and it seems like beyond quantizing the position and scale it's
also doing some rudimentary auto-hinting. That said, the auto-hinting
doesn't do that much for us, and the fact that it horizontally snaps
coordinates to thirds of a pixel instead of whole pixels makes things
worse in terms of legibility at small pixel sizes, so ultimately it's
better with our own handling anyway.
I extensively compared the result of Apple's option with our own manual
quantization here and I'm pretty sure this will always match the whole
pixel sizes, and where it differs (other than things like crossbars) it
seems to make glyphs generally more legible not less.
- Default ssh_term to xterm-256color to eliminate fallback assignments
- Remove base64 and replace infocmp -Q2 with standard -0 -x options for
compatibility
- Use process substitution instead of intermediate ssh_config variable
- Always set TERM explicitly since ssh_term is always defined
The Ghostty Apple ID has been frozen. I'm working on figuring out how to
get it back. In the meantime, this switches the notarization to my
personal Apple ID.
I originally created the dedicated Apple ID to limit access since we
were using app passwords. But I've since discovered that we can create
API tokens that have limited access, so I don't think this is a problem
anymore.

- Simplify feature detection to use single wildcard check
- Replace ssh_env array with simple ssh_term string variable
- Use TERM environment prefix instead of save/restore pattern
- Remove unnecessary backgrounded subshell for cache operations
Nerd font icons were ***WAY*** too big depending on your font setup,
this is because we were always using the full cell height when the nerd
font patcher instead uses an "icon height" for most things. The patcher
calculates the icon height as two thirds of the font's cap height and
one third of the line height, but I've chosen to instead use 1.2 times
the cap height for more consistent results across fonts-- if the user
wants their icons bigger, they can use the `adjust-icon-height` metric
modifier (and they can also use it to make them smaller if they want
that for some reason).
I also adjusted the attributes to user horizontal cover + vertical fit
for `^` stretch modes (proportional scaling but scale up), which makes
it so that it never exceeds the cell size, since first it covers
horizontally and then scales down to fit vertically if necessary;
previously, if there were a particularly wide glyph that was scaled with
cover/cover it would exceed the available width and overflow in to
neighboring cells which wasn't good.
- Remove complex ssh_exported_vars tracking and local environment
modification in favor of trusting Ghostty's local environment
- Replace regex patterns with glob-based feature detection for better
performance
- Fix local variable declaration consistency throughout
- Streamline logic while maintaining all functionality
Icons were often WAY too big before because they were filling the whole
cell in height, which isn't great lol. This commit adds an `icon_height`
metric which is used to constrain glyphs that shouldn't be the size of
the entire cell.
This was subtly wrong in a way that was most obvious when text switched
from regular to bold, where it would seem to wiggle since the bearings
of each letter would shift by a pixel in either direction. This affected
applications like fzf which uses bold to dynamically highlight the line
you have selected.

This PR changes `font.Collection` to automagically adjust the sizes of
added fonts so that their metrics (specifically their ex height, or
their ideograph character width if they have one) match the primary
font. This is like
[`font-size-adjust`](https://developer.mozilla.org/en-US/docs/Web/CSS/font-size-adjust)
from CSS.
This is a big win for users who use mixed writing systems and rely
heavily on fallback fonts. For example, in #7774 it's pointed out that
CJK characters are not very well harmonized with existing Latin glyphs,
well:

This also improves our handling of the horizontal alignment of fallback
glyphs. It's not an ideal solution; it only works for glyphs narrower
than the cell width because it messes with ligatures if we include
glyphs wider than the cell width; and most things would look better if
the center were proportionally remapped based on the ratio from the
glyph advance to the cell width, but that messes with glyphs designed to
align vertically so it can't be done, instead the original advance width
is centered in the cell width.
Previously produced very wrong values when calling Collection.setSize,
since it was assuming that the provided face had the same point size as
the primary face, which isn't true during resize-- so instead we just
have faces keep track of their set size, this is generally useful.

This updates the macOS apprt to implement the `OPEN_URL` apprt action to
use the NSWorkspace APIs instead of the `open` command line utility.
As part of this, we removed the `ghostty_config_open` libghostty API and
instead introduced a new `ghostty_config_open_path` API that returns the
path to open, and then we use the `NSWorkspace` APIs to open it (same
function as the `OPEN_URL` action).

In #7808, we stopped using PS0 to reset the cursor shape because
restoring PS0 in __ghostty_preexec was causing issues (#7802).
The alternate approach of printing the cursor reset escape sequence
directly from __ghostty_preexec caused a new issue: the input cursor
would persist longer than intended, such as when a suspended vim process
was restored to the foreground.
This change takes a different approach. We now conditionally add the
cursor shape escape sequences to PS0 (and PS1, for consistency) when
they don't already appear. The fixes the cursor shape reset problem.
The main downside to this approach is that PS0 will continue to contain
this escape sequence; it won't be cleared/reset in __ghostty_preexec for
the reasons described in #7808. This feels like an acceptable outcome
because there's no harm in the modified PS0 existing for the life of the
bash session (rather than it being modified and then restored for each
command cycle), and it's consistent with how some other terminals' bash
integration works (e.g. kitty).
The nerd font patcher uses `ypadding` as a single subtraction from the
cell height, which means that half of it should go to the top padding
and the other half to the bottom, but we were setting it for both the
top and bottom! This was making the heavy brackets way too small lol
(0.4 of the cell height instead of 0.7)
#7834 introduced the *opposite* problem to what it fixed haha. This
fixes it for real!

This better harmonizes fallback fonts with the primary font by matching
the heights of lowercase letters. This should be a big improvement for
users who use mixed scripts and so rely heavily on fallback fonts.

This generally adjusts the bearings of any glyph whose original advance
was narrower than the cell, which helps a lot with proportional fallback
glyphs so they aren't just left-aligned. This only applies to situations
where the glyph was originally narrower than the cell, so that we don't
mess up ligatures, and this centers the old advance width in the new one
rather than adjusting proportionally, because otherwise we can mess up
glyphs that are meant to align with others when placed vertically.

This implements the core changes necessary to open urls using an apprt
action rather than doing it directly from the core.
Implements the open_url action in the GTK apprt.
Note that this should not be merged until a macOS-savvy developer can
add an implementation of the open_url action for the macOS apprt.

We can reintroduce `advance` if we ever want to do proportional string
drawing, but we don't use it anywhere right now. And we also don't need
`sprite` anymore since that was just there to disable constraints for
sprites back when we did them on the GPU.
As discussed in https://github.com/ghostty-org/ghostty/discussions/3134
To allow for the option to render bold text in a different colour for
better visibility as an extension of `bold-is-bright`.
This is a feature that is available in other terminals.
Fixes#7820, and while fixing that I noticed that we need to respect the
cell width constraints since certain glyphs should not expand to 2
cells; before fixing that the heavy bracket would align differently
depending on if it had whitespace after it, which was obviously wrong
and looked terrible.
Fixes#7673
This adds `Ctrl+Alt+T` as a KDE shortcut to the desktop file. If Konsole
is installed (or any other prorgam that has the same shortcut) the user
will need to go into the KDE system settings and manually reassign the
`Ctrl+Alt+T` shortcut to Ghostty.
If Ghostty is the only terminal installed that claims that shortcut KDE
_should_ automatically enable the shortcut (but YMMV).
Non-KDE systems will ignore this setting and if the user desires a
global shortcut to open a Ghostty window it will need to be accomplished
in other ways.

This mostly applies to powerline glyphs, but is also relevant for heavy
bracket characters, which need to always be 1 wide otherwise they look
silly because they misalign depending on if there's a space after them
or not.
