Color Theme

The project uses the Catppuccin Frappé theme, providing a pleasant and high-contrast visual experience. Colors are defined as CSS variables for easy customization.

Customization

Theme Configuration via TypeScript

You can configure the theme programmatically:

1. Using the init function with options:

init({ theme: 'frappe' }); // or 'one-dark'

2. Changing theme at runtime:

setTheme('one-dark'); // or 'frappe'

The theme selection is persisted in localStorage and will be restored on page reload.

Fonts and Styling via CSS

You can customize fonts and other styles by creating your own configuration file. Include it after the base CSS and theme files:

<link rel="stylesheet" href="dist/kolmo.css">
<link rel="stylesheet" href="dist/themes/frappe.css">  <!-- or other theme -->
<link rel="stylesheet" href="path/to/your-config.css">

Available font variables:

:root {
  --kolmo-font-family: 'Your Font', monospace;
  --kolmo-font-size: 16px;
  --kolmo-line-height: 1.6;
  --kolmo-font-weight-normal: 400;
  --kolmo-font-weight-bold: 600;
}

Optional styling variables:

:root {
  --kolmo-block-padding: 1.5rem;
  --kolmo-block-border-radius: 8px;
}

See themes/config.css for a complete example of customization options.

Theme Customization

The project uses the Catppuccin Frappé theme by default. You can create your own theme by overriding the CSS variables:

1. Create a new CSS file (e.g., my-theme.css)
2. Define your color variables:

:root {
  --kolmo-comment: #666666;      /* Comments */
  --kolmo-char: #98c379;         /* Characters */
  --kolmo-number: #d19a66;       /* Numbers */
  --kolmo-constructor: #c678dd;  /* Constructors */
  --kolmo-symbol: #56b6c2;       /* Special symbols (λ, Π, ∀) */
  --kolmo-operator: #e06c75;     /* Operators */
  --kolmo-declaration: #c678dd;  /* Keywords: data, import */
  --kolmo-definition: #d19a66;   /* Keywords: def, gen */
  --kolmo-control: #e5c07b;      /* Keywords: if, else, case */
  --kolmo-variable: #61afef;     /* Variables */
  --kolmo-match: #98c379;        /* Keywords: match, switch */
  --kolmo-delimiter: #c678dd;    /* Delimiters: (), [], {} */
  --kolmo-punctuation: #e5c07b;  /* Punctuation: , ; : . */
}

/* Optional: Override the background and text colors */
.kolmo-syntax {
  color: #abb2bf;               /* Default text color */
  background-color: #282c34;    /* Background color */
}

3. Include your theme file after the default theme:

<link rel="stylesheet" href="dist/kolmo.css">
<link rel="stylesheet" href="path/to/my-theme.css">
