Significant rework that also removes a lot of unnecessarily duplicated
work while rebuilding cells in both renderers. Fixes multiple issues
with decorations and bg colors on wide chars and ligatures, while
reducing the amount of special case handling required.
This was recently introduced a few days ago. Unfortunately, this doesn't
work as expected. The "function" modifier is not actually the fn key
but used by macOS to represent a variety of "functional" key presses.
This breaks other bindings such as #2411.
I can't find a source on the internet that reliably tells me how we
can detect fn key presses, but I do find a number of sources that tell
us we can't.
- Limit max amplitude relative to cell width to avoid being too wavy
- Fix application of xiaolin-wu's for anti-aliasing too always be at
least 1px thick.
- Fix height calculation to avoid clipping bottom of wave at small
sizes.
This fixes a longstanding piece of tech debt which caused all sorts of
bugs. Instead of trying to jam cursorPosCallback into a modsChanged
event we bring out the link refreshing into a dedicated method that is
shared.
Ghostty was previously treating shift as a way to always stop mouse
reporting. That's true for mouse button events, but not for mouse
movement events. For mouse movement events, shift should be treated as
a modifier until a button (any mouse button) is pressed. Once it is
pressed, we pause mouse reporting until all buttons are released.
Found by @ldemailly. This matches the behavior of Kitty, Alacritty,
WezTerm, and xterm.
Fixes#2364
This adds the bold, italic, and bold italic variants of JB Mono so it is
built-in. This also fixes up the naming convention for the embedded font
files across tests and removes redundant embedded font files.
Metal needed to be changed to account for wide chars having decorations
on the right half and OpenGL needed to account for multiple glyphs being
under the cursor at once (decorations and combining marks) as well as
wide chars.
This makes sure that underline styles are consistent and not stretched,
and avoids rendering overlapping text decorations or extraneous
background cells for the right halves of wide chars.
