βcarbon.js is the easiest way to create beautiful images of your source code.β
This package uses an R6 api to interact with carbon.js and create
directly from the console carbon images.

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.

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)
gandafields 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: 14Open 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
Tinyurl
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 π¦
- When
add_tinyurl <- TRUE- Created in R using the Carbonate π¦ Check out this script at π https://tinyurl.com/2n72r6pk
- Manual
- Using
tweet_statusyou can write your own status.
- Using
x <- carbonate::carbon$new()
x$tweet <- TRUE
x$carbonate()Post process (Batch)
If you have images stored in x$carbons you can post them also in a
tweet using.
# for multiple png attachments
x$rtweet(x$carbons,media_type = 'png') #using default status
# subsets of images
x$rtweet(status='These are images',x$carbons[c(1,3)],media_type = 'png')
# for gifs
x$rtweet(status='This is a gif', x$carbons,media_type = 'gif')Post image processing
All carbon outputs are collected and saved in the list x$carbons
