Toit on your computer
A language for your everyday tools.
Write a script, run it, and build on it. Toit works on your computer without an embedded device; many of the tools in the SDK are themselves written in Toit.
Install Toit →Your first command-line tool
Install the SDK, save this program as greet.toit, and run the command shown here.
The main function receives the program’s arguments. A block visits each name and prints
a greeting.
There is no project setup needed for this example.
main arguments:
if arguments.is-empty:
print "Usage: greet.toit NAME ..."
return
arguments.do: |name|
print "Hello, $name!"
$ toit run greet.toit -- Ada LinusHello, Ada! Hello, Linus!
The CLI package
Build command-line applications.
pkg-cli provides argument parsing, typed options, subcommands, and generated help. It also supports shell completion for Bash, Zsh, and Fish.
The toit command-line tool is itself written in Toit, using this package.

As a tool grows, the same package provides configuration storage, caching, and output with selectable verbosity and text or JSON formats.

Indentation gives code its structure. Lambdas and blocks let you pass behavior to functions. Classes and types help describe larger programs.

Start with the work you have.
Toit is worth trying for small utilities, automation, and data processing. The standard library and community packages provide a starting point for your own tools.
