NAME

FFI::TinyCC::Inline - Embed Tiny C code in your Perl program

VERSION

version 0.28

SYNOPSIS

use FFI::TinyCC::Inline qw( tcc_inline );

tcc_inline q{
  int square(int num)
  {
    return num*num;
  }
};

print square(4), "\n"; # prints 16

use FFI::TinyCC::Inline qw( tcc_eval );

# sets value to 6:
my $value = tcc_eval q{
  int main(int a, int b, int c)
  {
    return a + b + c;
  }
}, 1, 2, 3;

DESCRIPTION

This module provides a simplified interface to FFI::TinyCC, that allows you to write Perl subs in C. It is inspired by XS::TCC, but it uses FFI::Platypus to create bindings instead of XS.

OPTIONS

You can specify Tiny C options using the scoped pragmata, like so:

use FFI::TinyCC::Inline options => "-I/foo/include -L/foo/lib -DFOO=1";

# prints 1
print tcc_eval q{
#include <foo.h> /* will search /foo/include
int main()
{
  return FOO; /* defined and set to 1 */
}
};

FUNCTIONS

tcc_inline

tcc_inline $c_code;

Compile the given C code using Tiny C and inject any functions found into the current package. An exception will be thrown if the code fails to compile, or if FFI::TinyCC::Inline does not recognize one of the argument or return types.

tcc_inline q{
  int foo(int a, int b, int c)
  {
    return a + b + c;
  }
};

print foo(1,2,3), "\n"; # prints 6

The special argument type of (int argc, char **argv) is recognized and will be translated from the list of arguments passed in. Example:

tcc_inline q{
  void foo(int argc, const char **argv)
  {
    int i;
    for(i=0; i<argc; i++)
    {
      puts(argv[i]);
    } 
  }
};

foo("one", "two", "three"); # prints "one\ntwo\nthree\n"

tcc_eval

tcc_eval $c_code, @arguments;

This compiles the C code and executes the main function, passing in the given arguments. Returns the result.

BUNDLED SOFTWARE

This package also comes with a parser that was shamelessly stolen from XS::TCC, which I strongly suspect was itself shamelessly "borrowed" from Inline::C::Parser::RegExp

The license details for the parser are:
