Yard
Yard is an funny programming language compiler and interpreter written in pure Rust.
Its a functional language, having no concept of classes or inheritance. Types are static and must be known at compile time.
It contains features such as:
- a COMEFROM keyword (inverse goto)
- a
don't
code block which never executes - no if. only
unless
, an inverted version of if. Meaning a block gets executed if the expression is false - three spaces start a single line comment
- many ways of making comments:
// comment
,:REM: comment
,# comment
,-- comment --
cuz we can
