Squirrel bindings

Guide in bindings

Not full guide but some brief introduction. To get deeper into bindings you need to study samples or read the code of SqRat

Example

Basic Includes

#include <sqrat.h> #include <sqModules.h>

Create a module

Simple bind of cpp function

.Func(const char *fn, bool must_exist, const char *__name__, SqObjPtr &exports, std::string &out_err_msg)

.Func(name:string, cpp_function:function of basic squirrel types (int, float, bool, char*, void))

param const char *fn

name of the file to load

param bool must_exist

if set to false treat missing file as success (return true)

param const char *__name__

value of module’s __name__ field (set nullptr to use actual file name)

param SqObjPtr &exports

object to store export to

:param name

function should return type that can be converted to squirrel basic types

Bind function that work with Squirrel stack

TableBase& SquirrelFunc(const SQChar* name, SQFUNCTION func, SQInteger nparamscheck, const SQChar *typemask=nullptr,
                          const SQChar *docstring=nullptr, SQInteger nfreevars=0, const Object *freevars=nullptr)

name should be string, func should be function that works with Quirrel

nparamscheck - number of arguments of function. If negative - function can have at least this number of arguments but can accept more.

typemask - optional typemask (see sq_setparamscheck in API)

docstring - optional docstring, nfreevars and freevars - free variables of function.

Bind classes, constants and values
