Perhaps you found it, but thought it wasn't complete because it was
too small! Smalltalk syntax is incredibly simple (Forth is the only
language I know which has a simpler syntax).


The BNF for Smalltalk can be found in the draft ANSI Smalltalk Standard
document; here's one reference:

[Note that there is an additional "file-out" syntax used to represent
Smalltalk in external text files, but that varies slightly between the
various implementations]
