Forth Programming Language, hosted by Lua.
- Compiles directly to (optimized) Lua source code
- Modeless with no interpretation mode
- Uses Lua call semantics, no return stack
- Lua table and array support
- Fixes Lua's accidental global problem
- Seamless Love2D and TIC-80 integration
- Self-hosted compiler (eventually)
| Operation | Array | Table |
|---|---|---|
| Create | [ 1 2 3 ] | { key1 val1 } |
| Append | tbl item append | |
| Insert new | tbl idx item insert | value -> tbl.key or tbl key value ! |
| Overwrite | tbl idx item ! | value -> tbl.key or tbl key value ! |
| Lookup | tbl idx @ | tbl.key or tbl key @ |
| Remove | tbl idx remove | tbl key nil ! |
| Remove & Return | tbl idx #( table.remove 2 ) | |
| Size | tbl size |
| Operation | Syntax |
|---|---|
| Call Lua function (2 parameters) | 2 8 #( math.pow 2 ) |
| Call nullary Lua function (no parameters) | #( os.time ) |
| Call Lua (binary) function and ignore return value | tbl 2 #( table.remove 2 0 ) |
| Call Lua (unary) method | #( astr:sub 1 ) |
| Property lookup | math.pi |
