Description
The mojo
CLI provides all the tools you need for Mojo development, such as commands to run, compile, and package Mojo code. A list of all commands are listed below, and you can learn more about each one by adding the --help
option to the command (for example, mojo package --help
).
However, you may omit the run
and repl
commands. That is, you can run a Mojo file by simply passing the filename to mojo
:
mojo hello.mojo
And you can start a REPL session by running mojo
with no commands.
To update Mojo to the latest version, use the modular
tool:
modular update mojo
You can check your current version with mojo --version
. For information about Mojo updates, see the Mojo changelog.
