carbon.js is the easiest way to create beautiful images of your source code.”

This package uses an R6 api to interact with carbon.js and create directly from the console carbon images.

Like the image below:

Installation

#remotes::install_github('yonicd/carbonate')
install.packages('carbonate')

Usage

Initialize new carbon object

library(carbonate)

The default code in the carbon object is taken from the clipboard.

x <- carbon$new()

But can also be defined inline. Code can be a character object of any length.

x <- carbon$new(readLines('DESCRIPTION'))

The code is kept in the object and can be changed at any time.

The main job of the R6 object is to convert all the options into a uri that is sent to the carbon url page, where it is processed.

Personal Configuration

Users can use a file called carbon.yml and place it in their home directory (~) to override the packages defaults in order to create a session peristent carbon template they like. The config file controls all the public carbon object fields. The following is an example of such a configuration file.

These fields will set

  • The palette (rgba) g and a fields to 175 and 0.7 respectively
  • The template will be set to panda-syntax
  • The font to Fira Code
  • The padding around the output will be made tighter than the system defaults 11px and 14px.
palette:
- g: 175.0
- a: 0.7
template: panda-syntax
font_family: Fira Code
padding_vertical: 11
padding_horizontal: 14

Open carbon code in browser

x$browse()

Set the download directory

x$download_path <- file.path('README_files/download')

Carbonate code directly to file

This function depends on RSelenium

x$carbonate(file = 'myfile.png')

x$template <-'cobalt'
x$carbonate(file = 'new_template.png')

x$font_family <-'IBM Plex Mono'
x$carbonate(file = 'new_font.png')

Carbonate code directly to file in specific directory

Closing Browsers

Closing all instances of open browsers used by RSelenium.

x$stop_all()

Sharing

You can also put a tinyurl link as a watermark on the image produced that will open to the carbon.now.sh page that has the code in the image.

x$add_tinyurl <- TRUE
x$carbonate(file = 'tiny_url.png')

If you just want the tinyurl link without the image to use in a tweet you can create it using

x$tiny()
#> [1] "https://tinyurl.com/2n72r6pk"

Or you can put the link directly on your clipboard

x$tiny(clip = TRUE)
clipr::read_clip()
Direct

You can also directly tweet the image. An automatic status is created with two options

  • Default
    • Created in R using the Carbonate
