Mitchell Hashimoto 2f4af5eb87 Changed behaviour of bold-color (#7871)
Continuation of discussion in
https://github.com/ghostty-org/ghostty/discussions/3134

This changes the behaviour of the new bold-color option to only affect
the default foreground text when set to a static colour. By using a
static colour, the remaining colours are rendered as bright.

/// You can generate the list of valid values using the CLI:
///
/// ghostty +list-fonts
///
/// This configuration can be repeated multiple times to specify preferred
/// fallback fonts when the requested codepoint is not available in the primary
/// font. This is particularly useful for multiple languages, symbolic fonts,
/// etc.
///
/// Notes on emoji specifically: On macOS, Ghostty by default will always use
/// Apple Color Emoji and on Linux will always use Noto Emoji. You can
/// override this behavior by specifying a font family here that contains
/// emoji glyphs.
///
/// The specific styles (bold, italic, bold italic) do not need to be
/// explicitly set. If a style is not set, then the regular style (font-family)
/// will be searched for stylistic variants. If a stylistic variant is not
/// found, Ghostty will use the regular style. This prevents falling back to a
/// different font family just to get a style such as bold. This also applies
/// if you explicitly specify a font family for a style. For example, if you
/// set `font-family-bold = FooBar` and "FooBar" cannot be found, Ghostty will
/// use whatever font is set for `font-family` for the bold style.
///
/// Finally, some styles may be synthesized if they are not supported.
/// For example, if a font does not have an italic style and no alternative
/// italic font is specified, Ghostty will synthesize an italic style by
/// applying a slant to the regular style. If you want to disable these
/// synthesized styles then you can use the `font-style` configurations
/// as documented below.

/// You can disable styles completely by using the `font-style` set of
/// configurations. See the documentation for `font-style` for more information.

/// specify the value as `""` (empty string) to reset the list and then set the
/// new values. For example:
///
/// font-family = ""
/// font-family = "My Favorite Font"
///
/// Setting any of these as CLI arguments will automatically clear the

/// keyboard layouts. For example, `a` will match the `a` key on a
/// QWERTY keyboard, but will match the `q` key on a AZERTY keyboard
/// (assuming US physical layout).
///
/// For Unicode codepoints, matching is done by comparing the set of
/// modifiers with the unmodified codepoint. The unmodified codepoint is
/// sometimes called an "unshifted character" in other software, but all
/// modifiers are considered, not only shift. For example, `ctrl+a` will match
/// `a` but not `ctrl+shift+a` (which is `A` on a US keyboard).

/// For example, `KeyA` will match the physical `a` key on a US standard
/// keyboard regardless of the keyboard layout. These are case-sensitive.
///
/// For aesthetic reasons, the w3c codes also support snake case. For
/// example, `key_a` is equivalent to `KeyA`. The only exceptions are
/// function keys, e.g. `F1` is `f1` (no underscore). This is a consequence
/// of our internal code using snake case but is purposely supported
/// and tested so it is safe to use. It allows an all-lowercase binding
/// which I find more aesthetically pleasing.
///
/// Function keys such as `insert`, `up`, `f5`, etc. are also specified
/// using the keys as specified by the previously linked W3C specification.
///
/// Physical keys always match with a higher priority than Unicode codepoints,
/// so if you specify both `a` and `KeyA`, the physical key will always be used
/// regardless of what order they are configured.
///
/// Valid modifiers are `shift`, `ctrl` (alias: `control`), `alt` (alias: `opt`,
/// `option`), and `super` (alias: `cmd`, `command`). You may use the modifier
/// or the alias. When debugging keybinds, the non-aliased modifier will always
/// be used in output.
///
/// Note: The fn or "globe" key on keyboards are not supported as a
/// modifier. This is a limitation of the operating systems and GUI toolkits
/// that Ghostty uses.
///
/// Some additional notes for triggers:
///
/// * modifiers cannot repeat, `ctrl+ctrl+a` is invalid.
///
/// * modifiers and keys can be in any order, `shift+a+ctrl` is *weird*,
/// but valid.
///
/// * only a single key input is allowed, `ctrl+a+b` is invalid.
///
/// You may also specify multiple triggers separated by `>` to require a
/// sequence of triggers to activate the action. For example,
/// `ctrl+a>n=new_window` will only trigger the `new_window` action if the
/// user presses `ctrl+a` followed separately by `n`. In other software, this
/// is sometimes called a leader key, a key chord, a key table, etc. There
/// is no hardcoded limit on the number of parts in a sequence.
///
/// Warning: If you define a sequence as a CLI argument to `ghostty`,
/// you probably have to quote the keybind since `>` is a special character
/// in most shells. Example: ghostty --keybind='ctrl+a>n=new_window'
///
/// A trigger sequence has some special handling:
///
/// * Ghostty will wait an indefinite amount of time for the next key in
/// the sequence. There is no way to specify a timeout. The only way to
/// force the output of a prefix key is to assign another keybind to
/// specifically output that key (e.g. `ctrl+a>ctrl+a=text:foo`) or
/// press an unbound key which will send both keys to the program.
///
/// * If a prefix in a sequence is previously bound, the sequence will
/// override the previous binding. For example, if `ctrl+a` is bound to
/// `new_window` and `ctrl+a>n` is bound to `new_tab`, pressing `ctrl+a`
/// will do nothing.
///
/// * Adding to the above, if a previously bound sequence prefix is
/// used in a new, non-sequence binding, the entire previously bound
/// sequence will be unbound. For example, if you bind `ctrl+a>n` and
/// `ctrl+a>t`, and then bind `ctrl+a` directly, both `ctrl+a>n` and
/// `ctrl+a>t` will become unbound.
///

///
/// Action is the action to take when the trigger is satisfied. It takes the

///
/// * `ignore` - Do nothing, ignore the key input. This can be used to
/// black hole certain inputs to have no effect.
///
/// * `unbind` - Remove the binding. This makes it so the previous action
/// is removed, and the key will be sent through to the child command
/// if it is printable. Unbind will remove any matching trigger,
/// including `physical:`-prefixed triggers without specifying the
/// prefix.
///
/// * `csi:text` - Send a CSI sequence. e.g. `csi:A` sends "cursor up".
///
/// * `esc:text` - Send an escape sequence. e.g. `esc:d` deletes to the
/// end of the word to the right.
///
/// * `text:text` - Send a string. Uses Zig string literal syntax.
/// e.g. `text:\x15` sends Ctrl-U.
///
/// * All other actions can be found in the documentation or by using the
/// `ghostty +list-actions` command.
///
/// Some notes for the action:
///
/// * The parameter is taken as-is after the `:`. Double quotes or
/// other mechanisms are included and NOT parsed. If you want to
/// send a string value that includes spaces, wrap the entire
/// trigger/action in double quotes. Example: `--keybind="up=csi:A B"`
///
/// There are some additional special values that can be specified for
/// keybind:
///
/// * `keybind=clear` will clear all set keybindings. Warning: this
/// removes ALL keybindings up to this point, including the default
/// keybindings.
///
/// The keybind trigger can be prefixed with some special values to change
/// the behavior of the keybind. These are:
///
/// * `all:` - Make the keybind apply to all terminal surfaces. By default,
/// keybinds only apply to the focused terminal surface. If this is true,
/// then the keybind will be sent to all terminal surfaces. This only
/// applies to actions that are surface-specific. For actions that
/// are already global (e.g. `quit`), this prefix has no effect.
///
/// Available since: 1.0.0
///
/// * `global:` - Make the keybind global. By default, keybinds only work
/// within Ghostty and under the right conditions (application focused,
/// sometimes terminal focused, etc.). If you want a keybind to work
/// globally across your system (e.g. even when Ghostty is not focused),
/// specify this prefix. This prefix implies `all:`. Note: this does not
/// work in all environments; see the additional notes below for more
/// information.
///
/// Available since: 1.0.0 (on macOS)
/// Available since: 1.2.0 (on GTK)
///
/// * `unconsumed:` - Do not consume the input. By default, a keybind
/// will consume the input, meaning that the associated encoding (if
/// any) will not be sent to the running program in the terminal. If
/// you wish to send the encoded value to the program, specify the
/// `unconsumed:` prefix before the entire keybind. For example:
/// `unconsumed:ctrl+a=reload_config`. `global:` and `all:`-prefixed
/// keybinds will always consume the input regardless of this setting.
/// Since they are not associated with a specific terminal surface,
/// they're never encoded.
///
/// Available since: 1.0.0
///
/// * `performable:` - Only consume the input if the action is able to be
/// performed. For example, the `copy_to_clipboard` action will only
/// consume the input if there is a selection to copy. If there is no
/// selection, Ghostty behaves as if the keybind was not set. This has
/// no effect with `global:` or `all:`-prefixed keybinds. For key
/// sequences, this will reset the sequence if the action is not
/// performable (acting identically to not having a keybind set at
/// all).
///
/// Performable keybinds will not appear as menu shortcuts in the
/// application menu. This is because the menu shortcuts force the
/// action to be performed regardless of the state of the terminal.
/// Performable keybinds will still work, they just won't appear as
/// a shortcut label in the menu.
///
/// Available since: 1.1.0
///
/// Keybind triggers are not unique per prefix combination. For example,
/// `ctrl+a` and `global:ctrl+a` are not two separate keybinds. The keybind
/// set later will overwrite the keybind set earlier. In this case, the
/// `global:` keybind will be used.
///
/// Multiple prefixes can be specified. For example,
/// `global:unconsumed:ctrl+a=reload_config` will make the keybind global
/// and not consume the input to reload the config.
///
/// Note: `global:` is only supported on macOS and certain Linux platforms.
///
/// On macOS, this feature requires accessibility permissions to be granted
/// to Ghostty. When a `global:` keybind is specified and Ghostty is launched
/// or reloaded, Ghostty will attempt to request these permissions.
/// If the permissions are not granted, the keybind will not work. On macOS,
/// you can find these permissions in System Preferences -> Privacy & Security
/// -> Accessibility.
///
/// On Linux, you need a desktop environment that implements the
/// [Global Shortcuts](https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.GlobalShortcuts.html)
/// protocol as a part of its XDG desktop protocol implementation.
/// Desktop environments that are known to support (or not support)
/// global shortcuts include:
///
/// - Users using KDE Plasma (since [5.27](https://kde.org/announcements/plasma/5/5.27.0/#wayland))
/// and GNOME (since [48](https://release.gnome.org/48/#and-thats-not-all)) should be able
/// to use global shortcuts with little to no configuration.
///
/// - Some manual configuration is required on Hyprland. Consult the steps
/// outlined on the [Hyprland Wiki](https://wiki.hyprland.org/Configuring/Binds/#dbus-global-shortcuts)
/// to set up global shortcuts correctly.
/// (Important: [`xdg-desktop-portal-hyprland`](https://wiki.hyprland.org/Hypr-Ecosystem/xdg-desktop-portal-hyprland/)
/// must also be installed!)
///
/// - Notably, global shortcuts have not been implemented on wlroots-based
/// compositors like Sway (see [upstream issue](https://github.com/emersion/xdg-desktop-portal-wlr/issues/240)).
