So today I am going to go over installing Crystal. I will be working on a MacBook for this, but its pretty similar to most other systems.
Homebrew
First off we need to make sure we install Homebrew it very simple to install. Be aware during install you may be asked you to install Xcode Command Line Tools, if so just say yes.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Cystal
With Homebrew installed we can now move on to installing Crystal, the current version at time of writing this is (1.0.0). You will need to enter the following commands into your terminal window.
# Install Crystal.
brew install crystal
# Check our Crystal version.
crystal -v
When we want to update Crystal to a new version, you would simply update brew first, then update Crystal.
# Update Homebrew.
brew update
# Update Crystal.
brew upgrade crystal
Crystal options
If you run crystal with no arguments, you can get a list of all available options for the compiler.
crystal
Usage: crystal [command] [switches] [program file] [--] [arguments]
Command:
init generate a new project
build build an executable
docs generate documentation
env print Crystal environment information
eval eval code from args or standard input
play starts Crystal playground server
run (default) build and run program
spec build and run specs (in spec directory)
tool run a tool
help, --help, -h show this help
version, --version, -v show version
Run a command followed by --help to see command specific information, ex:
crystal <command> --help
Well that’s a rather quick intro into getting Crystal setup, in my next posts I will go into setting up Lucky, which is a Framework similar to Rails but with some really nice features.
