0.1: Setup

[Experimental] In-page compiler

Although having a local SML/NJ available will make the tour easier to experiment with, it is possible to run the code samples on the page. The code runner comes with several libraries preloaded:

• the standard library, known as Basis
• SML/NJ’s library
• Concurrent ML

(NOTE: This is a new feature! Please file issues at the Github issue tracker.)

Prerequisites to running examples locally

• Install Standard ML of New Jersey
  • SML/NJ contains an interactive compiler manager and REPL which will be used for the examples throughout this tour
  • SML/NJ will also install an implementation of the standard library, the SML Basis Library.
• Ensure SML/NJ has been added to the path as appropriate for your architecture
• Clone the repository to get the examples and begin the tour!

Hello, world!

Note that REPL examples are cleaned up slightly; the text that appears in your REPL may differ somewhat, as a result.
