Introduction

SCBScript is a parser and execution engine for a script language similar to JavaScript. It is easy to implement and comes with a source code debugger. Since it is developed in C#, you can import and use C# objects and methods with it.

Implementation Example

It can be easily implemented as follows:

// Initialize system objects

scbscript.SystemObjectManager.SetSystemObjectTypes();

// Add native class type for script

scbscript.SystemObjectManager.AddClass(typeof(XXXX));

// Add native global methods class type for script

scbscript.SystemObjectManager.AddMethods(typeof(XXX));

// Script

string[] arguments = new string[] { ... };

Script script = new Script(arguments);

// Set a script source

if(script.SetScriptCodeFromFile(scriptSourcePath) > 0)

{

// Errors have been occurred

}

// Compile a script

if (script.Parse() != 0)

{

// Errors have been occurred

}

// Run

var interpreter = new Interpreter(script, false);

if(!interpreter.Run()) {

// Errors have been occurred

}

Script Example

The script adopts a syntax similar to JavaScript, as shown below:

//Define value

start = 1;

end = 100;

// Define function

function sum(start, end) {

s = 0;

// For syntax

for(i = start; i <= end; i++) s += i;

// Assign in function

start = 0;

end = 0;

// Return

return s;

}

// Function call

s0 = sum(start, end);

printf("Sum(%d - %d) : %d\n", start, end, s0);

// Interporation string

start = 50;

end = 150;

printf($"Sum({start} - {end}) : {sum(start, end)}\n");

// Array

ar = [ 1, 3, 5, 7, 9, 2, 4, 6, 8];

ar2 = [ 10, 11, 12, 13, 14, 15];

// Array conatnation

ar3 = ar + ar2;

printf('Array[2] : %d\n', ar2[2]);

// Foreach array

i = 0;

foreach(item in ar3) {

// Switch - case - match - default

switch(item) {

case 3:

case 4:

printf("@Array (%d) : %d\n", i, item);

break;

case 7:

case 8:

printf("#Array (%d) : %d\n", i, item);

break;

match $ >= 10 && $ < 13:

printf("<Array (%d) : %d\n", i, item);

break;

default:

printf("Array (%d) : %d\n", i, item);

break;

}

i++;

}

// Parallel expansion assignment

(a1, a2, aa[*]) = ar;

printf($"a1 : {a1}, a2 : {a2}\n");

foreach(item in aa) {

printf("Array aa : %d\n", item);

}

(bb[*], b2, b1) = ar2;

printf($"b1 : {b1}, b2 : {b2}\n");

foreach(item in bb) {

printf("Array bb : %d\n", item);

}

// Hash

hs = {

"abc" : 1,

"def" : 2,

"efg" : 3,

"hij" : 4,

"klm" : 5,

"nop" : 6,

"qrs" : 7,

"tuv" : 8,

"wxy" : 9,

"z" : 10

};

v = hs["klm"];

printf("Hash [klm] : %d\n", v);

v = hs.qrs;

printf("Hash.qrs : %d\n", v);

hs["123"] = 100;

hs["456"] = 101;

hs["789"] = 102;

// Foreach hash

foreach(item in hs) {

printf("Hash [%s] : %d\n", item.key, item.value);

}

// Regular expressions

var s0 = "abcdefg12345ABCDEFG67890";

if(s0 in *"[^0-9]+([0-9]+)[^0-9]+([0-9]+)") {

printf("Regex match count : %d\n", $#);

printf("Match all $$ : '%s'\n", $$);

printf("Match group $1 : '%s'\n", $1);

printf("Match group $2 : '%s'\n", $2);

}

if(s0 in *"([a-z]+)[^A-Z]+([A-Z]+)") {

printf("Regex match count : %d\n", $#);

printf("Match all $$ : '%s'\n", $$);

for(var i = 0; i < $#; i++) {

printf("Match group $[%d] : '%s'\n", i, $[i]);

}

}
