// up the vtable in order to get the voffset required to calculate the this
// pointer. While you're doing that, you might as well store the function
// pointer in the vtable. By doing this, they combine the m_func_address and
// m_vtable_index fields into one, and they distinguish between them by
// ensuring that function pointers always point to even addresses but vtable
// indices are always odd:
//

// vendors, including IBM's VisualAge and XLC compilers, recent versions of
// Open64, Pathscale EKO, and Metrowerks' 64-bit compilers. A simpler scheme
// used by earlier versions of GCC is also very common. SGI's now

Squirrel 3.1 stable
--------------------------------------------------------
What is in this distribution?
squirrel
static library implementing the compiler and interpreter of the language
sqstdlib
the standard utility libraries
sq
stand alone interpreter
doc
The manual
etc
a minimalistic embedding sample
samples
samples programs
HOW TO COMPILE
---------------------------------------------------------
CMAKE USERS
.........................................................
If you want to build the shared libraries under Windows using Visual
Studio, you will have to use CMake version 3.4 or newer. If not, an
earlier version will suffice. For a traditional out-of-source build
under Linux, type something like
$ mkdir build # Create temporary build directory
$ cd build
$ cmake .. # CMake will determine all the necessary information,
# including the platform (32- vs. 64-bit)
$ make
$ make install
$ cd ..; rm -r build
The default installation directory will be /usr/local on Unix platforms,
and C:/Program Files/squirrel on Windows. The binaries will go into bin/
and the libraries into lib/. You can change this behavior by calling CMake like
this:
$ cmake .. -DCMAKE_INSTALL_PREFIX=/some/path/on/your/system
With the CMAKE_INSTALL_BINDIR and CMAKE_INSTALL_LIBDIR options, the directories
the binaries & libraries will go in (relative to CMAKE_INSTALL_PREFIX)
can be specified. For instance,
$ cmake .. -DCMAKE_INSTALL_LIBDIR=lib64
will install the libraries into a 'lib64' subdirectory in the top
source directory. The public header files will be installed into the directory
the value of CMAKE_INSTALL_INCLUDEDIR points to. If you want only the
binaries and no headers, just set -DSQ_DISABLE_HEADER_INSTALLER=ON, and no
header files will be installed.
Under Windows, it is probably easiest to use the CMake GUI interface,
although invoking CMake from the command line as explained above
should work as well.
GCC USERS
.........................................................
There is a very simple makefile that compiles all libraries and exes
from the root of the project run 'make'
for 32 bits systems
$ make
for 64 bits systems
$ make sq64
VISUAL C++ USERS
.........................................................
Open squirrel.dsw from the root project directory and build(dho!)
DOCUMENTATION GENERATION
.........................................................
To be able to compile the documentation, make sure that you have Python
installed and the packages sphinx and sphinx_rtd_theme. Browse into doc/
and use either the Makefile for GCC-based platforms or make.bat for
Windows platforms.

-fixed some debug info imprecision
***2003-10-01 ***
***version 0.4 alpha***
-faster VM
-sq_call will pop arguments and closure also in case of failure
-fixed a bug in sq_remove
-now the VM detects delegation cycles(and throws an exception)
-new operators ++ and --

-fixed some expression precedence issue
-fixed bug in sq_arraypop
***2003-09-15 ***
***version 0.3 alpha***
-fixed a bug in array::insert()
-optional Unicode core(define SQUNICODE or _UNICODE on Win32)
-sq_compiler uses a new reader function SQLEXREADFUNC
-the debug hook passes 'l' instead of 'line' for line callbacks
and 'c' instead of 'call' for call callbacks
-new array.extend() bulit-in function
-new API sq_clone()
***2003-09-10 ***
***version 0.2 pre-alpha***
-new completely reentrant VM (sq_open and sq_close are now obsolete)
-sq_newvm() has a new prototype
-allocators are now global and linked in the VM
-_newslot meta method added

.. _sq_setparamscheck:
.. c:function:: SQRESULT sq_setparamscheck(HSQUIRRELVM v, SQInteger nparamscheck, const SQChar * typemask)
:param HSQUIRRELVM v: the target VM
:param SQInteger nparamscheck: defines the parameters number check policy (0 disables the param checking). If nparamscheck is greater than 0, the VM ensures that the number of parameters is exactly the number specified in nparamscheck (eg. if nparamscheck == 3 the function can only be called with 3 parameters). If nparamscheck is less than 0 the VM ensures that the closure is called with at least the absolute value of the number specified in nparamcheck (eg. nparamscheck == -3 will check that the function is called with at least 3 parameters). The hidden parameter 'this' is included in this number; free variables aren't. If SQ_MATCHTYPEMASKSTRING is passed instead of the number of parameters, the function will automatically infer the number of parameters to check from the typemask (eg. if the typemask is ".sn", it is like passing 3).
:param const SQChar * typemask: defines a mask to validate the parametes types passed to the function. If the parameter is NULL, no typechecking is applied (default).
:remarks: The typemask consists in a zero terminated string that represent the expected parameter type. The types are expressed as follows: 'o' null, 'i' integer, 'f' float, 'n' integer or float, 's' string, 't' table, 'a' array, 'u' userdata, 'c' closure and nativeclosure, 'g' generator, 'p' userpointer, 'v' thread, 'x' instance(class instance), 'y' class, 'b' bool. and '.' any type. The symbol '|' can be used as 'or' to accept multiple types on the same parameter. There isn't any limit on the number of 'or' that can be used. Spaces are ignored so can be inserted between types to increase readability. For instance to check a function that expect a table as 'this' a string as first parameter and a number or a userpointer as second parameter, the string would be "tsn|p" (table,string,number or userpointer). If the parameters mask is contains fewer parameters than 'nparamscheck', the remaining parameters will not be typechecked.
Sets the parameter validation scheme for the native closure at the top position in the stack. Allows you to validate the number of parameters accepted by the function and optionally their types. If the function call does not comply with the parameter schema set by sq_setparamscheck, an exception is thrown.
*.eg*
::
//example
SQInteger testy(HSQUIRRELVM v)
{
SQUserPointer p;
const SQChar *s;
SQInteger i;
//no type checking, if the call complies with the mask
//surely the functions will succeed.
sq_getuserdata(v,1,&p,NULL);
sq_getstring(v,2,&s);
sq_getinteger(v,3,&i);
//... do something
return 0;

By default Squirrel strings are plain 8-bits ASCII characters; however if the symbol
'SQUNICODE' is defined the VM, compiler and API will use 16-bit characters (UCS2).
.. _squirrel_64bits:

.. _userdata_alignment:
------------------
Userdata Alignment
------------------
.. index:: single: Userdata Alignment
Both class instances and userdatas can have a buffer associated to them.
Squirrel specifies the alignment(in bytes) through the preprocessor defining 'SQ_ALIGNMENT'.
By default SQ_ALIGNMENT is defined as 4 for 32-bit builds and 8 for 64-bit builds and builds that use 64-bit floats.
It is possible to override the value of SQ_ALIGNMENT respecting the following rules.
SQ_ALIGNMENT shall be less than or equal to SQ_MALLOC alignments, and it shall be power of 2.
.. note:: This only applies for userdata allocated by the VM, specified via sq_setclassudsize() or belonging to a userdata object.
userpointers specified by the user are not affected by alignment rules.

Squirrel's VM can be compiled without its compiler by defining 'NO_COMPILER' in the C++ preprocessor.
When 'NO_COMPILER' is defined all function related to the compiler (eg. sq_compile) will fail. Other functions
that conditionally load precompiled bytecode or compile a file (eg. sqstd_dofile) will only work with
precompiled bytecode.

Compiling a script
==================
You can compile a Squirrel script with the function *sq_compile*.::
typedef SQInteger (*SQLEXREADFUNC)(SQUserPointer userdata);
SQRESULT sq_compile(HSQUIRRELVM v,SQLEXREADFUNC read,SQUserPointer p,
const SQChar *sourcename,SQBool raiseerror);
In order to compile a script is necessary for the host application to implement a reader
function (SQLEXREADFUNC); this function is used to feed the compiler with the script
data.
The function is called every time the compiler needs a character; It has to return a
character code if succeed or 0 if the source is finished.
If sq_compile succeeds, the compiled script will be pushed as Squirrel function in the
stack.
.. :note::
In order to execute the script, the function generated by *sq_compile()* has
to be called through *sq_call()*
Here an example of a 'read' function that read from a file: ::
SQInteger file_lexfeedASCII(SQUserPointer file)
{
int ret;
char c;
if( ( ret=fread(&c,sizeof(c),1,(FILE *)file )>0) )
return c;
return 0;

{
sq_compile(v,file_lexfeedASCII,f,filename,1);

When the compiler fails for a syntax error it will try to call the 'compiler error handler';
this function must be declared as follow: ::
typedef void (*SQCOMPILERERROR)(HSQUIRRELVM /*v*/,const SQChar * /*desc*/,const SQChar * /*source*/,
SQInteger /*line*/,SQInteger /*column*/);
and can be set with the following API call::
void sq_setcompilererrorhandler(HSQUIRRELVM v,SQCOMPILERERROR f);

The parameters is an handle to the calling VM and the return value is an integer
respecting the following rules:
* 1 if the function returns a value
* 0 if the function does not return a value
* SQ_ERROR runtime error is thrown
In order to obtain a new callable squirrel function from a C function pointer, is necessary
to call sq_newclosure() passing the C function to it; the new Squirrel function will be
pushed in the stack.
When the function is called, the stackbase is the first parameter of the function and the
top is the last. In order to return a value the function has to push it in the stack and
return 1.
Function parameters are in the stack from position 1 ('this') to *n*.
*sq_gettop()* can be used to determinate the number of parameters.
If the function has free variables, those will be in the stack after the explicit parameters
an can be handled as normal parameters. Note also that the value returned by *sq_gettop()* will be
affected by free variables. *sq_gettop()* will return the number of parameters plus
number of free variables.
Here an example, the following function print the value of each argument and return the
number of arguments. ::

{
SQInteger nargs = sq_gettop(v); //number of arguments

Debug Interface
===============
The squirrel VM exposes a very simple debug interface that allows to easily built a full
featured debugger.
Through the functions sq_setdebughook and sq_setnativedebughook is possible in fact to set a callback function that
will be called every time the VM executes an new line of a script or if a function get
called/returns. The callback will pass as argument the current line the current source and the
current function name (if any).::
SQUIRREL_API void sq_setdebughook(HSQUIRRELVM v);
or ::
SQUIRREL_API void sq_setnativedebughook(HSQUIRRELVM v,SQDEBUGHOOK hook);
The following code shows how a debug hook could look like(obviously is possible to
implement this function in C as well). ::
function debughook(event_type,sourcefile,line,funcname)
{
local fname=funcname?funcname:"unknown";
local srcfile=sourcefile?sourcefile:"unknown"
switch (event_type) {
case 'l': //called every line(that contains some code)
::print("LINE line [" + line + "] func [" + fname + "]");
::print("file [" + srcfile + "]\n");
break;
case 'c': //called when a function has been called
::print("LINE line [" + line + "] func [" + fname + "]");
::print("file [" + srcfile + "]\n");
break;
case 'r': //called when a function returns
::print("LINE line [" + line + "] func [" + fname + "]");
::print("file [" + srcfile + "]\n");
break;
}
}
The parameter *event_type* can be 'l' ,'c' or 'r' ; a hook with a 'l' event is called for each line that
gets executed, 'c' every time a function gets called and 'r' every time a function returns.
A full-featured debugger always allows displaying local variables and calls stack.
The call stack information are retrieved through sq_getstackinfos()::
SQInteger sq_stackinfos(HSQUIRRELVM v,SQInteger level,SQStackInfos *si);
While the local variables info through sq_getlocal()::
SQInteger sq_getlocal(HSQUIRRELVM v,SQUnsignedInteger level,SQUnsignedInteger nseq);
In order to receive line callbacks the scripts have to be compiled with debug infos enabled
this is done through sq_enabledebuginfo(); ::
void sq_enabledebuginfo(HSQUIRRELVM v, SQInteger debuginfo);

Memory Management
========================
.. index:: single: Memory Management
Squirrel uses reference counting (RC) as primary system for memory management;
however, the virtual machine (VM) has an auxiliary
mark and sweep garbage collector that can be invoked on demand.
There are 2 possible compile time options:
* The default configuration consists in RC plus a mark and sweep garbage collector.
The host program can call the function sq_collectgarbage() and perform a garbage collection cycle
during the program execution. The garbage collector isn't invoked by the VM and has to
be explicitly called by the host program.
* The second a situation consists in RC only(define NO_GARBAGE_COLLECTOR); in this case is impossible for
the VM to detect reference cycles, so is the programmer that has to solve them explicitly in order to
avoid memory leaks.
The only advantage introduced by the second option is that saves 2 additional
pointers that have to be stored for each object in the default configuration with
garbage collector(8 bytes for 32 bits systems).
The types involved are: tables, arrays, functions, threads, userdata and generators; all other
types are untouched. These options do not affect execution speed.

When an exception is not handled by Squirrel code with a try/catch statement, a runtime
error is raised and the execution of the current program is interrupted. It is possible to
set a call back function to intercept the runtime error from the host program; this is
useful to show meaningful errors to the script writer and for implementing visual
debuggers.
The following API call pops a Squirrel function from the stack and sets it as error handler.::
SQUIRREL_API void sq_seterrorhandler(HSQUIRRELVM v);
The error handler is called with 2 parameters, an environment object (this) and a object.

This table is accessible only through the C API and is meant to be an utility structure
for native C library implementation.
For instance the sqstdlib(squirrel standard library)uses it to store configuration and shared objects
delegates.
The registry is accessible through the API call *sq_pushregistrytable()*.::
void sq_pushregistrytable(HSQUIRRELVM v);

.. _embedding_the_stack:
==========
The Stack
==========
Squirrel exchanges values with the virtual machine through a stack. This mechanism has
been inherited from the language Lua.
For instance to call a Squirrel function from C it is necessary to push the function and the
arguments in the stack and then invoke the function; also when Squirrel calls a C
function the parameters will be in the stack as well.
-------------
Stack indexes
-------------
Many API functions can arbitrarily refer to any element in the stack through an index.
The stack indexes follow those conventions:
* 1 is the stack base
* Negative indexes are considered an offset from top of the stack. For instance -1 isthe top of the stack.
* 0 is an invalid index
Here an example (let's pretend that this table is the VM stack)
+------------+--------------------+--------------------+
| **STACK** | **positive index** | **negative index** |
+============+====================+====================+
| "test" | 4 | -1(top) |
+------------+--------------------+--------------------+
| 1 | 3 | -2 |
+------------+--------------------+--------------------+
| 0.5 | 2 | -3 |
+------------+--------------------+--------------------+
| "foo" | 1(base) | -4 |
+------------+--------------------+--------------------+
In this case, the function *sq_gettop* would return 4;
------------------
Stack manipulation
------------------
The API offers several functions to push and retrieve data from the Squirrel stack.
To push a value that is already present in the stack in the top position::
void sq_push(HSQUIRRELVM v,SQInteger idx);
To pop an arbitrary number of elements::
void sq_pop(HSQUIRRELVM v,SQInteger nelemstopop);
To remove an element from the stack::
void sq_remove(HSQUIRRELVM v,SQInteger idx);
To retrieve the top index (and size) of the current
virtual stack you must call *sq_gettop* ::
SQInteger sq_gettop(HSQUIRRELVM v);
To force the stack to a certain size you can call *sq_settop* ::
void sq_settop(HSQUIRRELVM v,SQInteger newtop);
If the newtop is bigger than the previous one, the new positions in the stack will be
filled with null values.
The following function pushes a C value into the stack::
void sq_pushstring(HSQUIRRELVM v,const SQChar *s,SQInteger len);
void sq_pushfloat(HSQUIRRELVM v,SQFloat f);
void sq_pushinteger(HSQUIRRELVM v,SQInteger n);
void sq_pushuserpointer(HSQUIRRELVM v,SQUserPointer p);
void sq_pushbool(HSQUIRRELVM v,SQBool b);
this function pushes a null into the stack::
void sq_pushnull(HSQUIRRELVM v);
returns the type of the value in a arbitrary position in the stack::
SQObjectType sq_gettype(HSQUIRRELVM v,SQInteger idx);
the result can be one of the following values: ::
OT_NULL,OT_INTEGER,OT_FLOAT,OT_STRING,OT_TABLE,OT_ARRAY,OT_USERDATA,
OT_CLOSURE,OT_NATIVECLOSURE,OT_GENERATOR,OT_USERPOINTER,OT_BOOL,OT_INSTANCE,OT_CLASS,OT_WEAKREF
The following functions convert a squirrel value in the stack to a C value::
SQRESULT sq_getstring(HSQUIRRELVM v,SQInteger idx,const SQChar **c);
SQRESULT sq_getstringandsize(HSQUIRRELVM v,SQInteger idx,const SQChar **c,SQInteger size);
SQRESULT sq_getinteger(HSQUIRRELVM v,SQInteger idx,SQInteger *i);
SQRESULT sq_getfloat(HSQUIRRELVM v,SQInteger idx,SQFloat *f);
SQRESULT sq_getuserpointer(HSQUIRRELVM v,SQInteger idx,SQUserPointer *p);
SQRESULT sq_getuserdata(HSQUIRRELVM v,SQInteger idx,SQUserPointer *p,SQUserPointer *typetag);
SQRESULT sq_getbool(HSQUIRRELVM v,SQInteger idx,SQBool *p);
The function sq_cmp compares 2 values from the stack and returns their relation (like strcmp() in ANSI C).::
SQInteger sq_cmp(HSQUIRRELVM v);

.. _embedding_userdata_and_userpointers:
=========================
Userdata and UserPointers
=========================
Squirrel allows the host application put arbitrary data chunks into a Squirrel value, this is
possible through the data type userdata.::
SQUserPointer sq_newuserdata(HSQUIRRELVM v,SQUnsignedInteger size);
When the function *sq_newuserdata* is called, Squirrel allocates a new userdata with the
specified size, returns a pointer to his payload buffer and push the object in the stack; at
this point the application can do whatever it want with this memory chunk, the VM will
automatically take cake of the memory deallocation like for every other built-in type.
A userdata can be passed to a function or stored in a table slot. By default Squirrel
cannot manipulate directly userdata; however is possible to assign a delegate to it and
define a behavior like it would be a table.
Because the application would want to do something with the data stored in a userdata
object when it get deleted, is possible to assign a callback that will be called by the VM
just before deleting a certain userdata.
This is done through the API call *sq_setreleasehook*.::
typedef SQInteger (*SQRELEASEHOOK)(SQUserPointer,SQInteger size);
void sq_setreleasehook(HSQUIRRELVM v,SQInteger idx,SQRELEASEHOOK hook);
Another kind of userdata is the userpointer; this type is not a memory chunk like the
normal userdata, but just a 'void*' pointer. It cannot have a delegate and is passed by
value, so pushing a userpointer doesn't cause any memory allocation.::
void sq_pushuserpointer(HSQUIRRELVM v,SQUserPointer p);

.. _embedding_vm_initialization:
==============================
Virtual Machine Initialization
==============================
The first thing that a host application has to do, is create a virtual machine.
The host application can create any number of virtual machines through the function
*sq_open()*.
Every single VM that was created using *sq_open()* has to be released with the function *sq_close()* when it is no
longer needed.::
int main(int argc, char* argv[])
{
HSQUIRRELVM v;
v = sq_open(1024); //creates a VM with initial stack size 1024
//do some stuff with squirrel here
sq_close(v);
}

***************************
Embedding Squirrel
***************************
*This section describes how to embed Squirrel in a host application,
C language knowledge is required to understand this part of the manual.*
Because of his nature of extension language, Squirrel's compiler and virtual machine
are implemented as C library. The library exposes a set of functions to compile scripts,
call functions, manipulate data and extend the virtual machine.
All declarations needed for embedding the language in an application are in the header file 'squirrel.h'.
