A simple CLI theme

Note that this is in addition to the builtin theme. To use this theme, you can set it as the cli.theme option:

simple_theme(dark = getOption("cli_theme_dark", "auto"))

Arguments

dark	Whether the theme should be optiomized for a dark background. If "auto", then cli will try to detect this. Detection usually works in recent RStudio versions, and in iTerm on macOS, but not on other platforms.

Details

options(cli.theme = cli::simple_theme())

and then CLI apps started after this will use it as the default theme. You can also use it temporarily, in a div element:

cli_div(theme = cli::simple_theme())

themes, builtin_theme().
