IceCream.jl โ€” Never use println() to debug in Julia again.

IceCream.jl is a Julia port of the icecream library for Python.

Do you ever use print() or println() to debug your code? Of course you do. IceCream, or @ic for short, makes print debugging a little sweeter.

@ic() is like println(), but better:

  • It prints both expressions/variable names and their values.
  • It's 60% faster to type.
  • Data structures are pretty printed.
  • Output is syntax highlighted.
  • It optionally includes program context: filename, parent class, parent function, and line number.
using IceCream

@ic "Hello, world!"
@ic_log "Hello, world!"
>>> ic| program.jl:Main:3 > ("Hello, world!", "Hello, world!")
>>> ic| "Hello, world!"

Installation

] add IceCream

Usage

using IceCream
@ic "Hello, world!"  # or @ic("Hello, world!")
