feck's Introduction

feck - An interpreted language written in Ruby

Author: Anthony Burzillo


Language

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

Execuatables

Example program:

$ cat > test.fck
puts true and
false

See test_programs/ for more examples.

feck

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.

pics

Creates the symbol table and abstract syntax tree

$ ./pics test.fck

all

Run all four options of feck in order

$ ./all test.fck
puts@1 | true@1 | and@1 | false@2
======OUTPUT======
false
