snippet

snippet creates shareable, syntax-highlighted code images directly from your R session. It uses Typst for rendering, which can create png, pdf, or svg outputs.

Installation

Install the development version from GitHub:

pak::pak('christopherkenny/snippet')

snippet also requires Typst to be installed on your system. If you have Quarto installed, it will use its bundled Typst as a fallback. See typr for more details on the fallback strategy.

Usage

Pass code as a string, a character vector, or a file path. Leave code empty to use your clipboard:

library(snippet)

snippet('fit <- lm(mpg ~ wt, data = mtcars)\nsummary(fit)')

Themes

Two Flexoki themes are bundled. List available themes with snippet_themes():

snippet(
  'fit <- lm(mpg ~ wt, data = mtcars)',
  theme = 'Flexoki Dark'
)

Install additional themes by name with snippet_install_theme(). See the full list with snippet_known_themes():

snippet_install_theme('Dracula')
snippet_install_theme('Tomorrow Night')

snippet('fit <- lm(mpg ~ wt, data = mtcars)', theme = 'Dracula')

You can also install any theme from a URL or local file path:

snippet_install_theme('https://example.com/my-theme.tmTheme')
snippet_install_theme('/path/to/my-theme.tmTheme')

Window styles

The package supports Windows (default) and Mac browser controls.

snippet('x <- 1', style = 'mac')

Line numbers and width

snippet(
  'x <- 1:10\nmean(x)\nsd(x)',
  line_numbers = TRUE,
  width = 4
)
