bs_global_theme: Global theming

Description

bs_global_theme() creates a new (global) Bootstrap Sass theme which bs_theme_dependencies() (or sass_partial()) can consume (their theme argument defaults to bs_global_get(), which get the current global theme).

Usage

bs_global_theme(
  version = version_default(),
  bootswatch = NULL,
  bg = NULL,
  fg = NULL,
  primary = NULL,
  secondary = NULL,
  success = NULL,
  info = NULL,
  warning = NULL,
  danger = NULL,
  base_font = NULL,
  code_font = NULL,
  heading_font = NULL,
  ...
)
bs_global_set(theme = bs_theme())
bs_global_get()
bs_global_clear()
bs_global_add_variables(
  ...,
  .where = "defaults",
  .default_flag = identical(.where, "defaults")
)
bs_global_add_rules(...)
bs_global_bundle(...)
bs_global_theme_update(
  ...,
  bootswatch = NULL,
  bg = NULL,
  fg = NULL,
  primary = NULL,
  secondary = NULL,
  success = NULL,
  info = NULL,
  warning = NULL,
  danger = NULL,
  base_font = NULL,
  code_font = NULL,
  heading_font = NULL
)

Arguments

version

The major version of Bootstrap to use (see versions() for possible values). Defaults to the currently recommended version for new projects (currently Bootstrap 4).

bootswatch

The name of a bootswatch theme (see bootswatch_themes() for possible values). When provided to bs_theme_update(), any previous Bootswatch theme is first removed before the new one is applied (use bootswatch = "default" to effectively remove the Bootswatch theme).

bg

A color string for the background.

fg

A color string for the foreground.

primary

A color to be used for hyperlinks, to indicate primary/default actions, and to show active selection state in some Bootstrap components. Generally a bold, saturated color that contrasts with the theme's base colors.

secondary

A color for components and messages that don't need to stand out. (Not supported in Bootstrap 3.)

success

A color for messages that indicate an operation has succeeded. Typically green.

info

A color for messages that are informative but not critical. Typically a shade of blue-green.

warning

A color for warning messages. Typically yellow.

danger

A color for errors. Typically red.

base_font

The default typeface.

code_font

The typeface to be used for code. Be sure this is monospace!

heading_font

The typeface to be used for heading elements.

...

arguments passed along to bs_add_variables().

theme

a bs_theme() object.

.where

Whether to place the variable definitions before other Sass "defaults", after other Sass "declarations", or after other Sass "rules".

.default_flag

Whether or not to add a !default flag (if missing) to variable expressions. It's recommended to keep this as TRUE when .where = "defaults".

Value

functions that modify the global theme (e.g., bs_global_set()) invisibly return the previously set theme. bs_global_get() returns the current global theme.

Examples

# NOT RUN {
# Remember the global state now (so we can restore later)
theme <- bs_global_get()
# Use Bootstrap 3 (globally) with some theme customization
bs_global_theme(3, bg = "#444", fg = "#e4e4e4", primary = "#e39777")
if (interactive()) bs_theme_preview(with_themer = FALSE)
# If no global theme is active, bs_global_get() returns NULL
bs_global_clear()
bs_global_get()
# Restore the original state
bs_global_set(theme)

# }
