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

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.

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()You can also directly tweet the image. An automatic status is created with two options
- Default
- Created in R using the Carbonate 📦
- When
add_tinyurl <- TRUE- Created in R using the Carbonate 📦 Check out this script at 🔗 https://tinyurl.com/2n72r6pk
- Manual
- Using
tweet_statusyou can write your own status.
- Using
x <- carbonate::carbon$new()
x$tweet <- TRUE
x$carbonate()If you have images stored in x$carbons you can post them also in a
tweet using.
# for multiple png attachments
x$rtweet(x$carbons,media_type = 'png') #using default status

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')All carbon outputs are collected and saved in the list x$carbons
