cazzilli

Introduction

moved to https://codeberg.org/cage/cazzilli/

Cazzilli is a compiler for Monicelli that targets Common Lisp. For information about Monicelli point the browser to the original implementation.

The name of this compiler is a reference of a typical dish of southern Italian cuisine symbolically offered to a great film director from (Center)Northern Italy: Mario Monicelli, come fosse trazione per due.

Status

This project is in a very early status, but nevertheless is able to compile a simple example.

Examples from Original Implementation

• hello world.mc ::
works (compiles with warning, both lisp and monicelli);
• fibonacci.mc ::
works;
• factorial.mc ::
works;
• primes.mc ::
works;
• float.mc ::
works but see [[Differences in Semantics]]

Use

For End Users

compile and generate an executable with:

#+BEGIN_SRC sh $ cazzilli "source-file" "executable-file" #+END_SRC

Note that if already exists on your file system "executable-file" will be overwritten. Please remember this and also that there is NO WARRANTY.

For Developers

| name | parameter | |---------------------+-----------------------| | parser:parse-stream | a stream | |---------------------+-----------------------| | parser:parse-file | a pathname designator |

both functions above will return 4 values:

• the monicelli code compiled to lisp code (or nil if errors
occurred);
• al list of the errors occurred during compilation (or nil if no
errors occurred);
• a list of the warning occurred during compilation (if any);
• the environment;
• an AST (Abstract Syntax Tree) corresponding to the output of the
parser.

The last two are useful only for debugging purposes.

Notes

Differences in Grammars

1. Because of my laziness :) the "bit shift" statements must appear on
a single line.

#+BEGIN_SRC text con scappellamento a per #+END_SRC

is accepted but

#+BEGIN_SRC text con scappellamento a per #+END_SRC

is not. Note that:

#+BEGIN_SRC text con scappellamento a per #+END_SRC

is OK.

Of course patches are welcome.

1. Iff a variable is prefixed with the article "=l'=" the first
must precede the variable name without any spaces in between:

#+BEGIN_SRC text l'orologio #+END_SRC

is accepted but

#+BEGIN_SRC text l' orologio #+END_SRC

is not.

Also see BUGS.

Differences in Semantics

• By default a type Mascetti is assigned to a literal integer e.g.

#+BEGIN_SRC text 42 a posterdati #+END_SRC

will print * (see: ascii(7)), not 42.

• "a posterdati" statement does not print a newline by default.

BUGS

Known Bugs

Currently the compilation errors reported to the user are very poor. Hopefully this is going to be corrected soon; but do not hold your breath! ^_^;
