Transpiler

A variety of transpilers from different programming languages to JavaScript

PHP Transpiler

Key Features:

• Basic Syntax Conversion:

• PHP tags removal

• Variable prefix conversion ($var to php_variables.var)

• Echo statements to console.log

Control Structures:

• if/else/elseif

• for/while/foreach loops

• switch statements

Functions and Classes:

• Function declaration translation

• Basic class translation with constructor

• Visibility modifiers (public/private/protected)

Operators:

• Comparison operators

• Logical operators

• String concatenation (. to +)

Runtime Environment:

• PHP-style isset(), empty(), count() functions

• Variable scope emulation

• Basic error handling

Limitations

This is a basic transpiler that handles many common PHP constructs, but there are limitations:

• Doesn't fully support all PHP superglobals ($_GET, $_POST, etc.)

• Limited support for PHP's complex type juggling

• No support for PHP namespaces

• Limited class inheritance and interface support

• No support for PHP's reference system

Java Transpiler

Key Features:

• Package and import statements handling

• Class definition conversion

• Main method translation

Variable Declarations:

• Java type declarations to JavaScript let/const

• Final variables to const

Control Structures:

• if/else statements

• for/while loops

• switch statements

I/O Operations:

• System.out.println to console.log

• System.out.print to process.stdout.write

Methods and Constructors:

• Method declaration translation

• Constructor conversion

• Visibility modifiers handling

Runtime Environment:

• Basic Java classes emulation (System, Integer, Double)

• Collections (ArrayList, HashMap)

• Math utilities

• String utilities

Limitations

• This is a basic transpiler that handles many common Java constructs, but has some limitations:

• No support for Java packages and full module system

• Limited support for Java's type system and generics

• No support for Java's exception handling (try-catch with specific exceptions)

• Limited support for interfaces and abstract classes

• No support for Java's threading model

• Annotations are not processed
