Constants

Constants expose named Java values to scripts.

Constant Interface

org.densy.scriptify.api.script.constant.ScriptConstant

Create a constant:

ScriptConstant constant = ScriptConstant.of("appName", "Scriptify");

Or implement it:

public final class AppNameConstant implements ScriptConstant {
    @Override
    public String getName() {
        return "appName";
    }

    @Override
    public Object getValue() {
        return "Scriptify";
    }
}

Register Globally

script.getConstantManager().register(ScriptConstant.of("appName", "Scriptify"));
script.evalOneShot("appName");

Global constants are exported to the global module during compilation.

Export From a Module

SimpleScriptInternalModule app = new SimpleScriptInternalModule("app");
app.export(new ScriptConstantExport(ScriptConstant.of("name", "Scriptify")));
script.getModuleManager().addModule(app);

import { name } from "app";
name;

Constant Manager

ScriptConstantManager provides:

Map<String, ScriptConstant> getConstants();
ScriptConstant getConstant(String name);
void register(ScriptConstant constant);
void remove(String name);

Default implementation:

org.densy.scriptify.core.script.constant.StandardConstantManager

Built-In Core Constants

Constant	Value
baseDir	Current JVM working directory as an absolute string.
osName	System.getProperty("os.name").

These are exported by StandardScriptModule.

Deprecated Common Manager

CommonConstantManager is deprecated. Prefer module exports.
