snippit

creates syntax-highlighted code snippets in png or svg format. Installation like any standard go program:

go install github.com/juliusmh/snippit@latest

The snippit binary reads input from stdin, unless a positional parameter is passed. Reading a .go file from stdin:

cat main.go | snippit --syntax go --out snippet.png

Or running for a specific file:

snippit --syntax cpp --out snippet.svg src/main.cpp
