Struct ThemeBuilder 

pub struct ThemeBuilder { /* private fields */ }

Builder for constructing Theme values at runtime.

Required fields (name, author, bg, fg) are set in ThemeBuilder::new. All other fields default to None. Variant is auto-detected from bg luminance and contrast is auto-calculated from the bg/fg ratio unless set explicitly.

Examples

use chromata::{Color, Theme, ThemeBuilder};

let theme = ThemeBuilder::new("My Theme", "Author", Color::new(0, 0, 0), Color::new(255, 255, 255))
    .keyword(Color::from_hex(0xff79c6))
    .string(Color::from_hex(0xf1fa8c))
    .build();
assert!(theme.is_dark());

Implementations

impl ThemeBuilder

Create a new builder with the required fields.

pub fn variant(self, v: Variant) -> Self

Override the auto-detected variant.

pub fn contrast(self, c: Contrast) -> Self

Override the auto-calculated contrast.

pub fn cursor(self, c: Color) -> Self

Set the cursor color.

pub fn selection(self, c: Color) -> Self

Set the selection color.

pub fn line_highlight(self, c: Color) -> Self

Set the line highlight color.

pub fn gutter(self, c: Color) -> Self

Set the gutter color.

pub fn statusbar_bg(self, c: Color) -> Self

Set the status bar background color.

pub fn statusbar_fg(self, c: Color) -> Self

Set the status bar foreground color.

pub fn comment(self, c: Color) -> Self

Set the comment color.

pub fn keyword(self, c: Color) -> Self

Set the keyword color.

pub fn string(self, c: Color) -> Self

Set the string color.

pub fn function(self, c: Color) -> Self

Set the function color.

pub fn variable(self, c: Color) -> Self

Set the variable color.

pub fn type(self, c: Color) -> Self

Set the type color.

pub fn constant(self, c: Color) -> Self

Set the constant color.

pub fn operator(self, c: Color) -> Self

Set the operator color.

pub fn tag(self, c: Color) -> Self

Set the tag color.

pub fn error(self, c: Color) -> Self

Set the error color.

pub fn warning(self, c: Color) -> Self

Set the warning color.

pub fn info(self, c: Color) -> Self

Set the info color.

pub fn success(self, c: Color) -> Self

Set the success color.

pub fn red(self, c: Color) -> Self

Set the red accent color.

pub fn orange(self, c: Color) -> Self

Set the orange accent color.

pub fn yellow(self, c: Color) -> Self

Set the yellow accent color.

pub fn green(self, c: Color) -> Self
