user19870/cppsp: cppsp –a transpiled script-like language base on c++

cppsp -a transpiled script-like language base on c++

Download the cppsp_compiler.exe or compiler the sourcecode by yourself

• Requirement:prepare your own c++ compiler and set it’s folder to environment path(environment variable)
• Requirement:a 64bits c++ compiler to make sure exe can be open
• Optional: put the folder path of exe/elf/mach-o to environment
• remember delete _mac/_linux to make cppsp_compiler works
• (Optional) rename cppsp_compiler.exe(or cppsp_compiler) to any name you like to change compile command like:cppsp、abcdef….
• Install from cmd/console:

  curl -L -o cppsp_compiler.exe https://github.com/user19870/cppsp/raw/refs/heads/First/cppsp_compiler.exe

  curl -L -o cppsp_compiler https://github.com/user19870/cppsp/raw/refs/heads/First/cppsp_compiler_linux.delete_linux

  curl -L -o cppsp_compiler https://github.com/user19870/cppsp/raw/refs/heads/First/cppsp_compiler_mac.delete_mac

• Use cmd or other console to compiler .cppsp file:
  cppsp_compiler(if not in environment path:.\cppsp_compiler.exe or c:\...\cppsp_compiler.exe) script.cppsp
• Setting c++ include/lib folder by .ini file
  include.ini:C:…\include1,c:…\include2
  lib.ini:C:…\lib1,c:…\lib2

• can compile when there is only print(“hello world”) in .cppsp
• can use almost c++ header by import
• custom pattern-driven, nested, namespace-scoped templates
• can use c++ code by @inject and @function
• enable indentation and multi-line after v1.3
• declare multi variables with var…..type
• control variables inside keyword or globle

• #useclang or #usegcc : use clang++ or g++ compile command
• @command("..."): add command when compile like:-Os、-m64
• #overwrite:make @command() overwrite g++ …. or clang++ compile command like @command("g++ -Os -m64 -nostdlib -shared -o dll.dll dll.cpp") and add “*/” after int main(){..} also add “/*” in front of int main(){..}
• #skipcompile : skip g++/clang++ compile and directly run output
• import :import header in c++ and accept import iostream,cstdio,x,y,…..
• @function>: inject everything(void()、int()、bool()、even #define and using namespace) in > to the space under #include above int main().Better not put any word, symbol or blanks but enalbe “enter” or nothing after “>>” to make difference between operation like a>>b and >
• @inject(...) :inject everything in (…) to int main(){…} —-＠inject(....)and ＠inject("....") are both legal. ＠inject(….) belonging to line ast and ＠inject(“….”) belonging to token ast but ＠inject(….) will be transpiled before ＠inject(“….”) and any keyword belonging to token ast.)
• print(): print content to console like print(“12\n”,” “,1,” “,2.1,true,false,” “)
• input(): input data to variables
• var…..type: declare variables with/without values. Support multi variables and type can be written as int/float/char/string/bool. is a value but 1+1 not(it’s expression)
• if/else/else if(...){...}:similar to “if/else/else if” in c++ but enable syntax: if(input(x)>1). Can write cppsp keywords and operation( =,+,-,*,/,++….) in {…}
• for(...){...}:similae to “for” in c++ like for( type i=0,i0;i++,j++) or for(type i:x) . Can write cppsp keywords and operation( =,+,-,*,/,++….) in {…}
• function f()...:function f() type {...return...} will define a function with type, function f(){...} will define a void function,function f() will declare a void function, function f(){...return...} will define a function with auto in c++. Usages

function [std::pow,std::sort,abs,sqrt] // will regist functions from c++
// but template function still need  like  std::sort(x,x+5,()}>) 

Usecppfunction

• struct S{...} : define a structure and the name of structure will become a type ,so can use something like var….S. If write struct a b cwithout {} a ,b, and c will become type but won’t generate any c++ code
• @custom xxx("...",,...) : @custom can let users write own syntaxs. *”…” can generate code, is similar to it but will become a placeholder and replaced by parameter when the custom syntax is called.Code will generate in global and the inner of some cppsp keywords. namespace only accept one level like: namespace n{ @custom.... }

@custom subs(," sub(",,",",,")"," {return a-b;}")
subs(int ,int a,int b)

• control variables in cppsp once a line or separate by ;

• : c++ code or everything in will become an element of cppsp keyowds like :

  import math.h,iostream
print( )

import  string,iostream
var a,c,d =  1,

,4 int
var b = "hello world" string
var f1,f2,f3 float
var c1 char
var b1 =  bool
input(f1)
print(a," ",c," ",d," ",b," ",b1," ",f1)

import iostream
var x={1,2,3} int
@inject("x[0]=3;x[1]=2; x[2]=1;")
if(true) {
  x[0]=4
}
for(int i=0,i

＠command("-f1 -f2 ..... -f5") 
＠command("-f6 -f7 ....-f10") 

＠command("g++ -Os -m64 -nostdlib  -shared ") 
＠command(" -o dll.dll dll.cpp") 

@command("-mtune=native   -fomit-frame-pointer -static-libgcc   -ffunction-sections -fdata-sections -Wl,--gc-sections  -Wl,--as-needed  -s  -Wl,--strip-all  -Os -m64")
import iostream,vector
@functionusing namespace std;>>
print("12\n"," ",1," ",2.1,true,false," ")
print( "abc")
print(1,"\n") //abv
//print(1.1)
@inject(int x=1;int y=2;int z=3; auto is_bool = [](const std::string& s){ return s == "true" || s == "false";};)
input(x,y,z)
@function cars = {"Volvo", "BMW", "Ford", "Mazda"};};>>
print(x+y+z)

#overwrite
@command("g++ -Os -m64 -nostdlib  -shared   -o dll.dll dll.cpp")
@functionextern "C" __declspec(dllexport) int add(int a, int b) { return a * b;}>>
