feck - An interpreted language written in Ruby
Author: Anthony Burzillo
feck is a dynamically-typed, interpreted language. Some examples of feck features include parallel assignment and boolean operators with precedence.
$ cat > test.fck a, b, c = 5, "Hello, there" puts a, b, c $ ./feck test.fck 5 Hello, there nil
$ cat > test.fck x = 5 if x < 4 puts 1 elif true || false and true && false puts 2 else puts 3 * 2.5 end $ ./feck test.fck 7.5
To see the most current possibilites in feck, see its grammar in EBNF for in doc/feck_grammar.txt
$ cat > test.fck puts true and false
See test_programs/ for more examples.
Print out the tokens of the program:
$ ./feck -l puts@1 | true@1 | and@1 | false@2
Create a representation of the symbol table of the program (with dot installed):
$ ./feck -t test.fck | dot -T jpeg > table.jpg
Create a representation of the abstract syntax tree of the program (with dot installed):
$ ./feck -a test.fck | dot -T jpeg > tree.jpg
Run a program:
$ ./feck test.fck false
ifk - an interactive interpreter
Example usage (quit with ctrl-d):
$ ./ifk ifk:1 > puts true and ifk:2 ?> false false => false
The value following the '=>' is the result of the last expression evaluated.
Creates the symbol table and abstract syntax tree
$ ./pics test.fck
Run all four options of feck in order
$ ./all test.fck puts@1 | true@1 | and@1 | false@2 ======OUTPUT====== false
