Reproduction is to resize the window to it's minimum width and then
run `ghostty +list-themes`. Ghostty will crash because Zig for loops
don't like having a range where the end is smaller than the start.
This adds a "fancy" theme preview to the `+list-themes` CLI action.
By default, if the command is connected to a TTY, it will display the
fancy preview. If it is not connected to a TTY, or the user specifies
`--plain` on the command line, a simple list of themes will be printed
to stdout.
While in the preview `F1` or `?` will show a help screen.
The syntax of tagged unions is `tag:value`. This matches the tagged
union parsing syntax for keybindings (i.e. `new_split:right`).
I'm adding this now on its own without a user-facing feature because
I can see some places we might use this and I want to separate this out.
There is already a PR open now that can utilize this (#2231).
These oses don't supply a tty layer, which prevents us from using the
libvaxis tty. Eventually we can add in using stdout as a writer. For
now, we just don't pretty print there.
Add pretty printing to the +list-keybinds command. This is done by
bringing in a dependency on libvaxis to handle the styling. Pretty
printing happens automatically when printing to a tty, and can be
disabled either by redirecting output or using the flag `--plain`
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.
Fixes#1366
When we use `loadTheme`, we "replay" the configuration so that the theme
is the base configuration and everything else can override everything
the theme sets. During this process, we were not properly re-expanding
all the relative paths.
This fix works by changing our input tracking from solely tracking args
to tracking operations such as expansion as well. When we "replay" the
configuration we also replay operations such as path expansion with the
correct base path.
This also removes the `_inputs` special mechanism `cli/args.zig` had
because we can already do that ourselves using `parseManuallyHook`.
