Silicon is an alternative to Carbon implemented in Rust.

It can render your source code into a beautiful image.

Carbon is a wonderful tool to create a beautiful image of your source code.

But it is a web application, which brings the following disadvantages:

• Cannot work without Internet & browser.
• Doesn't work well with shell. (Although there is carbon-now-cli, its experience is not very good, especially when the network is not so good.)

However, Silicon doesn't have these problem. It's is implemented in Rust and can work without browser & Internet.

Silicon can render your source code on the fly while carbon-now-cli takes several seconds on it.

It's not as beautiful as Carbon...

cargo install silicon

Silicon is available on AUR (Thanks to @radmen).

You can install it with any AUR helpers you like.

eg.

pikaur -S silicon

sudo pacman -S --needed pkgconf freetype2 fontconfig libxcb xclip

Read code from file

silicon main.rs -o main.png 

Read code from clipboard, and copy the result image to clipboard(--to-clipboard is only available on Linux)

silicon --from-clipboard -l rs --to-clipboard

Use multiple fonts

silicon main.rs -o main.png -f 'Hack; SimSun'

Highlight specified line

silicon main.rs -o main.png --highlight-lines '1; 3-4'

Custom the image

silicon ./target/test.rs -o test.png \
    --shadow-color '#555' --background '#fff' \
    --shadow-blur-radius 30 --no-window-controls

Transparent background

The color can be #RGB[A] or #RRGGBB[AA]

silicon ./target/test.rs -o test.png --background '#fff0'
