Implementation resources

This page lists some resources for learning how to implement array languages.

Interpreting

• Let's build a simple interpreter for APL series (currently incomplete) on Mathspp Blog
• Parsing and Execution in the J dictionary

Compiling

Because traditional APL does not have a context-free grammar, the language must be modified or restricted in some way to allow it to be compiled. K and BQN have context-free grammars, making them immediately suitable for compilation.

• BQN implementation notes
• Aaron Hsu's tree manipulation talks describe a technique used in Co-dfns.
• Compiling APL to JavaScript describes some implementation decisions made in ngn/apl
