Setting up Standard ML Environment on Mac/Windows

Standard ML

This is a cool functional programming language. Here's my tips for gettings set up.

Download/Install SML

Visit the official website for Standard ML and go to the current release.

• For Windows it's as simple as downloading and running the MSI they list
• For Apple computers, do yourself a huge favor now and go first install Brew
  • Then you can simply run brew install smlnj and bam! you've got it.

You can use SML in both mac/windows by simply running sml in the command prompt or terminal (you may need to reopen the terminal after installing before it'll be in your PATH)

Download VSCode

• Get VSCode (no editor wars here... it's just simple and good. Use vim if you want)
• Install the extension it suggests when opening a *.sml file or get it Here if you aren't sure.
• Open VSCode settings from Preferences > Settings or something, and add this to your settings file if you dont want the sml.json warnings:

{
  "sml.ignoreMissingSmlDotJson": true
}

Exiting the SML process in your script

Add the following to the end of your *.sml scripts:

val _ = OS.Process.exit(OS.Process.success);

And also consider setting the CM_VERBOSE flag when running sml to avoid all the extra output if you don't need it.

# Mac/Linux
CM_VERBOSE=false sml example.sml

# Windows
set CM_VERBOSE=false & sml example.sml
