NAME
SPVM::Guides::LanguageSpecification - The SPVM 1.0 Language Specification
DESCRIPTION
The SPVM 1.0 Language Specification is described in this document. SPVM is in beta testing for the 1.0 release. Language specifications are subject to change without warning.
SPVM Language is designed to be used from Perl. Perl can call SPVM subroutines.
SPVM Language provides fast array operation and fast numeric calculation.
SPVM subroutines is executed by the SPVM Runtime. its can be converted to shared libraries or DLL.
SPVM Language can be converted to machine codes, and you can execute them as a single executable.
Executables contain not only Unix/Linux/macOS/ios executable, but also Windows Native Executable,
C99 compliant
C99-compliant compiler and runtime
The source code for the SPVM compiler and SPVM runtime is written in C and conforms to C99.
Note that this does not mean that the user cannot call C versions other than C99 (C11, GNU extensions, etc.) or code written in C ++ from SPVM. This means that the SPVM compiler and runtime must be C99 compliant.
Correspondence of type with C99
The SPVM type exactly matches the following C99 types:
| SPVM type | C99 type |
Description
|
byte
|
int8_t
|
SPVM byte type matches C99 int8_t type.
|
short
|
int16_t
|
SPVM short type matches the C99 int16_t type.
|
int
|
int32_t
|
SPVM int type matches the C99 int32_t type.
|
long
|
int64_t
|
SPVM long type matches C99 int64_t type.
|
float
|
float
|
SPVM float type matches the C99 float type.
|
double
|
double
|
SPVM double type matches C99 double.
|
Object type
|
void*
|
SPVM object type matches the C99 void* type.
|
Multiple numeric type
|
Numeric array type that matches tye type and the length of the fields of SPVM multiple numeric type
|
| For example, if the multiple numeric type is package Point_2i: mulnum_t {has x: int; has y: int;} It matches the type declared in C99 int32_t var[2]; |
