FFI::TinyCC::Inline - Embed Tiny C code in your Perl program
version 0.28
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;
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.
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 */
}
};
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 $c_code, @arguments;
This compiles the C code and executes the main function, passing in the given arguments. Returns the result.
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:
