Command Line Arguments

Here is a list of the different arguments that you are able to pass to the HaXe compiler.

These arguments can also be placed into a text file of one per line with the extension hxml. This file can then be passed directly to the haxe compiler as a build script.

Targets

These are the different targets and options provided with HaXe 2.05.

Each target and it's options may only be used once per call the compiler. --next can be used in hxml files to utilize multiple calls with one command.

C++

See: hxcpp for more information on setting up your environment to compile the C++ files.

• -cpp : compile code to C++ files

Javascript

See: Getting started with haXe/JS.

• -js : compile code to JavaScript file
• --js-namespace <namespace> : create a namespace where root types are defined

Neko

See: Getting started with haXe/Neko.

• -neko : compile code to Neko Binary
• -x : shortcut for compiling and executing a neko file
• --neko-source : keep generated neko source

Flash

See: Getting started with haXe/Flash.

• -as3 : generate AS3 code into target directory
• -swf : compile code to Flash SWF file
• -swf9 : compile code to Flash9 SWF file (Deprecated: Use -swf-version instead)
• -swf-version : change the SWF version (6 to 10). Implies the `-D flashN` switch, where `N` is the SWF version specified
• -swf-header : define SWF header (width:height:fps:color)
• -swf-lib : add the SWF library to the compiled SWF
• --flash-strict : more type strict flash API
• --flash-use-stage : place objects found on the stage of the SWF lib

PHP

See: Getting started with haXe/PHP.

• -php : generate PHP code into target directory
• --php-front : select the name for the PHP front file
• --php-lib : It's the path generated library, stored by defaut in the 'lib' sub directory.

XML

• -xml : generate XML types description

Compilation Options

• -main : select startup class
• -lib : use an haxelib library (-lib libname:version)
• -D : define a conditional compilation flag
  See: Conditional Compilation
• -resource [@name] : add a named resource file
• -debug : add debug information to the compiled code
• --no-opt : disable code optimizations
• --no-traces : don’t compile trace calls in the program
• --no-inline : disable inlining
• --remap : remap a package to another one
• -cp : add a directory to find source files

Macro Options

• ???

Compiler Interaction Options

• --display : display code tips (see the introductory blog post here)
• -v : turn on verbose mode
• -prompt : prompt on error
• --times : measure compilation times
• -help : Display this list of options
• --help : Display this list of options

Batch Processing Commands

• -cmd : run the specified command after successful compilation (Note: Version 2.04 and earlier will only run after a successful compile. Will not run without a target)
• --gen-hx-classes : generate hx headers from SWF9 file
• --next : separate several haxe compilations
• --no-output : compiles but does not generate any file
