Stated another way, all necessary global variables and functions are members of a big C++ object. This object's class is CPerlObj. This allows a Perl Host to have multiple, independent perl interpreters in the same process space. This is very important on Win32 systems as the overhead of process creation is quite high -- this could be even higher than the script compile and execute time for small scripts. The perl executable implementation on Win32 is composed of perl.exe (the Perl Host) and perlX.dll. (the Perl Core). This allows the same Perl Core to easily be embedded in other applications that use the perl interpreter. +-----------+ | Perl Host | +-----------+ ^ - | - v + | + v +-----------+ +-----------+ | Perl Core |<->| Extension | +-----------+ +-----------+ ... Defining PERL_OBJECT has the following effects: PERL CORE 1. CPerlObj is defined (this is the PERL_OBJECT) 2. all static functions that needed to access either global variables or functions needed are made member functions 3. all writable static variables are made member variables 4. all global variables and functions are defined as: - #define var CPerlObj::Perl_var + #define var CPerlObj::PL_var #define func CPerlObj::Perl_func - * these are in objpp.h + * these are in embed.h This necessitated renaming some local variables and functions that had the same name as a global variable or function. This was probably a _good_ thing anyway. EXTENSIONS 1. Access to global variables and perl functions is through a pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is made transparent to extension developers by the following macros: - #define var pPerl->Perl_var + #define var pPerl->PL_var #define func pPerl->Perl_func * these are done in objXSUB.h This requires that the extension be compiled as C++, which means that the code must be ANSI C and not K&R C. For K&R extensions, please see the C API notes located in Win32/GenCAPI.pl. This script creates a perlCAPI.lib that provides a K & R compatible C interface to the PERL_OBJECT. 2. Local variables and functions cannot have the same name as perl's variables or functions since the macros will redefine these. Look for this if you get some strange error message and it does not look like the code that you had written. This often happens with variables that are local to a function. PERL HOST 1. The perl host is linked with perlX.lib to get perl_alloc. This function will return a pointer to CPerlObj (the PERL_OBJECT). It takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h for more information on this). 2. The perl host calls the same functions as normally would be called in setting up and running a perl script, except that the functions are now member functions of the PERL_OBJECT. */ class CPerlObj; #define STATIC -#define CPERLscope(x) CPerlObj::x -#define CPERLproto CPerlObj * -#define _CPERLproto ,CPERLproto -#define CPERLarg CPerlObj *pPerl -#define CPERLarg_ CPERLarg, -#define _CPERLarg ,CPERLarg -#define PERL_OBJECT_THIS this -#define _PERL_OBJECT_THIS ,this -#define PERL_OBJECT_THIS_ this, -#define CALLRUNOPS (this->*PL_runops) -#define CALLREGCOMP (this->*PL_regcompp) -#define CALLREGEXEC (this->*PL_regexecp) +#define CPERLscope(x) CPerlObj::x +#define CALL_FPTR(fptr) (aTHXo->*fptr) +#define pTHXo CPerlObj *pPerl +#define pTHXo_ pTHXo, +#define aTHXo this +#define aTHXo_ this, +#define PERL_OBJECT_THIS aTHXo +#define PERL_OBJECT_THIS_ aTHXo_ +#define dTHXoa(a) pTHXo = a +#define dTHXo dTHXoa(PERL_GET_THX) + +#define pTHXx void +#define pTHXx_ +#define aTHXx +#define aTHXx_ + #else /* !PERL_OBJECT */ +#ifdef PERL_IMPLICIT_CONTEXT +# ifdef USE_THREADS +struct perl_thread; +# define pTHX register struct perl_thread *thr +# define aTHX thr +# define dTHR dNOOP +# else +# ifndef MULTIPLICITY +# define MULTIPLICITY +# endif +# define pTHX register PerlInterpreter *my_perl +# define aTHX my_perl +# endif +# define dTHXa(a) pTHX = a +# define dTHX dTHXa(PERL_GET_THX) +# define pTHX_ pTHX, +# define aTHX_ aTHX, +# define pTHX_1 2 +# define pTHX_2 3 +# define pTHX_3 4 +# define pTHX_4 5 +#endif + #define STATIC static #define CPERLscope(x) x -#define CPERLproto -#define _CPERLproto #define CPERLarg void #define CPERLarg_ #define _CPERLarg #define PERL_OBJECT_THIS #define _PERL_OBJECT_THIS #define PERL_OBJECT_THIS_ -#define CALLRUNOPS PL_runops -#define CALLREGCOMP (*PL_regcompp) -#define CALLREGEXEC (*PL_regexecp) +#define CALL_FPTR(fptr) (*fptr) #endif /* PERL_OBJECT */ -#define VOIDUSED 1 -#include "config.h" +#define CALLRUNOPS CALL_FPTR(PL_runops) +#define CALLREGCOMP CALL_FPTR(PL_regcompp) +#define CALLREGEXEC CALL_FPTR(PL_regexecp) +#define CALLREG_INTUIT_START CALL_FPTR(PL_regint_start) +#define CALLREG_INTUIT_STRING CALL_FPTR(PL_regint_string) +#define CALLREGFREE CALL_FPTR(PL_regfree) -#include "embed.h" +#ifdef PERL_FLEXIBLE_EXCEPTIONS +# define CALLPROTECT CALL_FPTR(PL_protect) +#endif +#define NOOP (void)0 +#define dNOOP extern int Perl___notused + +#ifndef pTHX +# define pTHX void +# define pTHX_ +# define aTHX +# define aTHX_ +# define dTHXa(a) dNOOP +# define dTHX dNOOP +# define pTHX_1 1 +# define pTHX_2 2 +# define pTHX_3 3 +# define pTHX_4 4 +#endif + +#ifndef pTHXo +# define pTHXo pTHX +# define pTHXo_ pTHX_ +# define aTHXo aTHX +# define aTHXo_ aTHX_ +# define dTHXo dTHX +#endif + +#ifndef pTHXx +# define pTHXx register PerlInterpreter *my_perl +# define pTHXx_ pTHXx, +# define aTHXx my_perl +# define aTHXx_ aTHXx, +# define dTHXx dTHX +#endif + #undef START_EXTERN_C #undef END_EXTERN_C #undef EXTERN_C #ifdef __cplusplus # define START_EXTERN_C extern "C" { # define END_EXTERN_C } # define EXTERN_C extern "C" #else # define START_EXTERN_C # define END_EXTERN_C -# define EXTERN_C +# define EXTERN_C extern #endif #ifdef OP_IN_REGISTER # ifdef __GNUC__ # define stringify_immed(s) #s # define stringify(s) stringify_immed(s) -#ifdef EMBED register struct op *Perl_op asm(stringify(OP_IN_REGISTER)); -#else -register struct op *op asm(stringify(OP_IN_REGISTER)); -#endif # endif #endif /* * STMT_START { statements; } STMT_END; * can be used as a single statement, as in * if (x) STMT_START { ... } STMT_END; else ... * * Trying to select a version that gives no warnings... */ #if !(defined(STMT_START) && defined(STMT_END)) # if defined(__GNUC__) && !defined(__STRICT_ANSI__) && !defined(__cplusplus) # define STMT_START (void)( /* gcc supports ``({ STATEMENTS; })'' */ # define STMT_END ) # else /* Now which other defined()s do we need here ???
