The Haxe Compiler then resolves the main class file and begins compilation.\nThe second question usually comes down to providing an argument specifying the desired target. Each Haxe target has a dedicated command line switch, such as\n--js <file_name>\nfor JavaScript and\n--php <directory>\nfor PHP. Depending on the nature of the target, the argument value is either a directory path (for\n--php\n,\n--cpp\n,\n--cs\n, and\n--java\n) or a file name.\nCommon arguments\nInput:\n-p <path>\n(or\n--class-path <path>\n) Add a class path where\n.hx\nsource files or packages (sub-directories) can be found.\n-L <library_name>\n(or\n--library <library_name>\n) Add a\nHaxelib\nlibrary. By default the most recent version in the local Haxelib repository is used. To require a specific library version use\n-L library_name:version\n. To require a version from git use\n-L library_name:git:https:\/\/github.com\/user\/project.git#commit\nwhere the optional #commit can be a branch, tag or commit hash.\n-m <dot_path>\n(or\n--main <dot_path>\n) Set the main class.\n-D <var[=value]>\n(or\n--define <var[=value]>\n) Define a\nconditional compilation flag\n.\nOutput:\n--js <file_name.js>\nGenerate\nJavaScript\nsource code in specified file.\n--swf <file_name.swf>\nGenerate the specified file as\nFlash\n.swf\n.\n--neko <file_name.n>\nGenerate\nNeko\nbinary as specified file.\n--php <directory>\nGenerate\nPHP\nsource code in specified directory. Use\n-D php7\nfor PHP7 source code.\n--cpp <directory>\nGenerate\nC++\nsource code in specified directory and compiles it using native C++ compiler.\n--cs <directory>\nGenerate\nC#\nsource code in specified directory and compiles it using native C# compiler.\n--java <directory>\nGenerate\nJava\nsource code in specified directory and compiles it using the Java Compiler. Add\n-D jvm\nto generate JVM byte code directly bypassing Java compilation step.\n--jvm <file_name.jar>\nGenerate\nJVM bytecode\nas a jar file.\n--python <file_name.py>\nGenerate\nPython\nsource code in the specified file.\n--lua <file_name.lua>\nGenerate\nLua\nsource code in the specified file.\n--hl <file_name.hl>\nGenerate\nHashLink\nbyte code in specified file.\n--cppia <file_name.cppia>\nGenerate the specified script as a\ncppia\nfile.\n-x <file>\nShortcut for compiling and executing a Neko file.\n--no-output\nCompile but do not generate any file.\n--interp\nInterpret the program using internal macro system.\nOther global arguments\n--run <module> [args...]\nCompile and execute a Haxe module with command line arguments.\n--xml <file>\nGenerate XML types description. Useful for API documentation generation tools like\nDox\n.\n--json <file>\nGenerate JSON types description.\n-v\n(or\n--verbose\n) Turn on verbose mode.\n--dce <std|full|no>\nSet the\nDead Code Elimination\nmode (default\nstd\n).\n--debug\nAdd debug information to the compiled code.\n-r <file>[@name]\n(or\n--resource <file>[@name]\n) Add a named resource file.\n--prompt\nPrompt on error.\n--cmd <command>\nRun the specified shell command after a successful compilation.\n--no-traces\nDon't compile trace calls in the program.\n--display\nDisplay code tips to provide\ncompletion information for IDEs and editors\n.\n--times\nMeasure compilation times.\n--no-inline\nDisable\ninlining\n.\n--no-opt\nDisable code optimizations.\n--remap <package:target>\nRemap a package to another one.\n--macro\nCall the given\ninitialization macro\nbefore typing anything else.\n--wait <host:port>\nWait on the given port for commands to run (see\nCompletion server\n).\n--connect <host:port>\nConnect on the given port and run commands there (see\nCompletion server\n).\n-C <dir>\n(or\n--cwd <dir>\n) Set current working directory.\nTarget specific arguments\n-D php-front=<filename>\nSelect the name for the php front file.\n-D php-lib=<filename>\nSelect the name for the php lib folder.\n-D php-prefix=<name>\nPrefix all classes with given name.\n--swf-version <version>\nChange the SWF version.\n--swf-header <header>\nDefine SWF header (width:height:fps:color).\n--swf-lib <file>\nAdd the SWF library to the compiled SWF.\n--swf-lib-extern <file>\nUse the SWF library for type checking.\n--flash-strict\nMore type strict flash API.\n--java-lib <file>\nAdd an external JAR or class directory library.\n--net-lib <file>[@std]\nAdd an external .NET DLL file.\n--net-std <file>\nAdd a root std .NET DLL search path.\n--c-arg <arg>\nPass option\narg\nto the native Java\/C# compiler.\nTrivia: Run commands after compilation\nUse\n--cmd\nto run the specified command after a successful compilation. It can be used to run (testing) tools or to directly run the build, e.g.\n--cmd java -jar bin\/Main.jar\n(for Java),\n--cmd node main.js\n(for Node.js) or\n--cmd neko Main.n\n(for Neko) etc.\nGlobal compiler configuration macros:\nIn order to include single modules, their paths can be listed directly on command line or in hxml:\nhaxe ... ModuleName pack.ModuleName\n. For more specific includes or excludes, use these\ninitialization macros\n:\n--macro include(pack:String, recursive=true, ?ignore:Array<String>, ?classPaths:Array<String>, strict=false)\nIncludes all modules in package pack in the compilation. If\nrecursive\nis true, the compiler recursively adds all sub-packages.\n--macro exclude(pack:String, recursive=true\nExclude a specific class, enum, or all classes and enums in a package from being generated. Excluded types become\nextern\n. If\nrecursive\nis true, the compiler recursively excludes all sub-packages.\n--macro excludeFile(fileName:String)\nExclude classes and enums listed from given external file (one per line) from being generated.\n--macro keep(?path:String, ?paths:Array<String>, recursive=true)\nMarks a package, module or sub-type dot path to be kept by DCE. This also extends to the sub-types of resolved modules. If\nrecursive\nis true, the compiler recursively keeps all sub-packages for package paths.\n--macro includeFile(file:String, position)\nEmbed a JavaScript file at compile time.\nposition\ncan be either \"top\", \"inline\" or \"closure\".\nThe full documentation of these methods can be found in the\nhaxe.macro.Compiler\nAPI documentation.\nHelp\nhaxe --version\nPrint the current Haxe compiler version.\nhaxe --help\nDisplay this list of options.\nhaxe --help-defines\nPrint help for all\ncompiler specific defines\n.\nhaxe --help-metas\nPrint help for all\ncompiler metadata\n.\nRelated content\nCompilation tutorials\nin the Haxe Code Cookbook.","attrs_markdown":"[![Haxe](https:\/\/haxe.org\/img\/haxe-logo-horizontal-on-dark.png)](https:\/\/haxe.org\/)\n\n- [Home](https:\/\/haxe.org\/)\n- [Download](https:\/\/haxe.org\/download\/)\n- [Blog](https:\/\/haxe.org\/blog\/)\n- [Use Cases](https:\/\/haxe.org\/use-cases\/)\n  -

The Haxe Compiler then resolves the main class file and begins compilation.\n\nThe second question usually comes down to providing an argument specifying the desired target. Each Haxe target has a dedicated command line switch, such as `--js <file_name>` for JavaScript and `--php <directory>` for PHP. Depending on the nature of the target, the argument value is either a directory path (for `--php`, `--cpp`, `--cs`, and `--java`) or a file name.\n\n##### [Common arguments](https:\/\/haxe.org\/manual\/compiler-usage.html#common-arguments)\n**Input:**\n\n- `-p <path>` (or `--class-path <path>`) Add a class path where `.hx` source files or packages (sub-directories) can be found.\n- `-L <library_name>` (or `--library <library_name>`) Add a [Haxelib](https:\/\/haxe.org\/manual\/haxelib.html) library. By default the most recent version in the local Haxelib repository is used. To require a specific library version use `-L library_name:version`.

It can be used to run (testing) tools or to directly run the build, e.g. `--cmd java -jar bin\/Main.jar` (for Java), `--cmd node main.js` (for Node.js) or `--cmd neko Main.n` (for Neko) etc.\n##### [Global compiler configuration macros:](https:\/\/haxe.org\/manual\/compiler-usage.html#global-compiler-configuration-macros)\nIn order to include single modules, their paths can be listed directly on command line or in hxml: `haxe ... ModuleName pack.ModuleName`. For more specific includes or excludes, use these [initialization macros](https:\/\/haxe.org\/manual\/macro-initialization.html):\n\n- `--macro include(pack:String, recursive=true, ?ignore:Array<String>, ?classPaths:Array<String>, strict=false)` Includes all modules in package pack in the compilation. If `recursive` is true, the compiler recursively adds all sub-packages.\n- `--macro exclude(pack:String, recursive=true` Exclude a specific class, enum, or all classes and enums in a package from being generated. Excluded types become `extern`. If `recursive` is true, the compiler recursively excludes all sub-packages.\n- `--macro excludeFile(fileName:String)` Exclude classes and enums listed from given external file (one per line) from being generated.\n- `--macro keep(?path:String, ?paths:Array<String>, recursive=true)` Marks a package, module or sub-type dot path to be kept by DCE. This also extends to the sub-types of resolved modules. If `recursive` is true, the compiler recursively keeps all sub-packages for package paths.\n- `--macro includeFile(file:String, position)` Embed a JavaScript file at compile time. `position` can be either \"top\", \"inline\" or \"closure\".\n\nThe full documentation of these methods can be found in the [`haxe.macro.Compiler`](http:\/\/api.haxe.org\/haxe\/macro\/Compiler.html) API documentation.\n\n##### [Help](https:\/\/haxe.org\/manual\/compiler-usage.html#help)\n- `haxe --version` Print the current Haxe compiler version.\n- `haxe --help` Display this list of options.\n- `haxe --help-defines` Print help for all [compiler specific defines](https:\/\/haxe.org\/manual\/compiler-usage-flags.html).\n- `haxe --help-metas` Print help for all [compiler metadata](https:\/\/haxe.org\/manual\/lf-condition-compilation.html).\n##### [Related content](https:\/\/haxe.org\/manual\/compiler-usage.html#related-content)\n- [Compilation tutorials](http:\/\/code.haxe.org\/category\/compilation\/) in the Haxe Code Cookbook.\n\n[Inline Constructors](https:\/\/haxe.org\/manual\/lf-inline-constructor.html)[Contribute to this page](https:\/\/github.com\/HaxeFoundation\/HaxeManual\/tree\/master\/content\/07-compiler-usage.md#L1-L104)[HXML](https:\/\/haxe.org\/manual\/compiler-usage-hxml.html)\n***\n\n- ##### [Home](https:\/\/haxe.org\/)\n  ##### [Download](https:\/\/haxe.org\/download\/)\n  ##### [Blog](https:\/\/haxe.org\/blog\/)\n  ##### [Support Plans](https:\/\/haxe.org\/foundation\/support-plans.html)\n- ##### [Use Cases](https:\/\/haxe.org\/use-cases\/)\n  - [Overview](https:\/\/haxe.org\/use-cases\/)\n  - [Games](https:\/\/haxe.org\/use-cases\/games\/)\n  - [Web](https:\/\/haxe.org\/use-cases\/web\/)\n  - [Mobile](https:\/\/haxe.org\/use-cases\/mobile\/)\n  - [Desktop](https:\/\/haxe.org\/use-cases\/desktop\/)\n  - [Command Line](https:\/\/haxe.org\/use-cases\/cli\/)\n  - [Cross Platform APIs](https:\/\/haxe.org\/use-cases\/cross-platform-apis\/)\n  - [Who Uses Haxe](https:\/\/haxe.org\/use-cases\/who-uses-haxe.html)\n- ##### [Haxe Foundation](https:\/\/haxe.org\/foundation\/)\n  - [About The Foundation](https:\/\/haxe.org\/foundation\/)\n  - [Who is who](https:\/\/haxe.org\/foundation\/people.html)\n  - [Jobs](https:\/\/haxe.org\/foundation\/jobs.html)\n  - [Supported Projects](https:\/\/haxe.org\/foundation\/supported-projects.html)\n  - [Support Plans](https:\/\/haxe.org\/foundation\/support-plans.html)\n  - [Donate](https:\/\/haxe.org\/foundation\/donate.html)\n  - [Branding](https:\/\/haxe.org\/foundation\/branding.html)\n  - [Shop](https:\/\/haxe.org\/foundation\/shop.html)\n  - [Open Source](https:\/\/haxe.org\/foundation\/open-source.html)\n  - [Contact](https:\/\/haxe.org\/foundation\/contact.html)\n- ##### [Learn Haxe](https:\/\/haxe.org\/documentation\/introduction)\n  - [Introduction](https:\/\/haxe.org\/documentation\/introduction\/)\n  - [Manual](https:\/\/haxe.org\/manual\/)\n  - [Code Cookbook](https:\/\/code.haxe.org\/)\n  - [API Documentation](https:\/\/api.haxe.org\/)\n  - [Videos](https:\/\/haxe.org\/videos\/)\n  - [Try Haxe online](https:\/\/try.haxe.org\/)\n  - [Haxelib](https:\/\/lib.haxe.org\/)\n\n© 2025 [Haxe Foundation](https:\/\/haxe.org\/foundation\/ \"Haxe Foundation Website\") \\| [Contribute to this page](https:\/\/github.com\/HaxeFoundation\/HaxeManual\/tree\/master\/content\/07-compiler-usage.md#L1-L104 \"Use Github to suggest an edit to this page\")\n\n![](https:\/\/www.facebook.com\/tr?id=1947619682232701&ev=PageView&noscript=1)\n\n![](https:\/\/www.facebook.com\/tr?id=335361176950894&ev=PageView&noscript=1)","attrs_readable_markdown":null,"meta_canonical":null}

Meta Title	Compiler Usage - Haxe - The Cross-platform Toolkit
Meta Description	Haxe is an open source toolkit based on a modern, high level, strictly typed programming language.
Meta Canonical	null
Boilerpipe Text	Basic Usage The Haxe Compiler is typically invoked from command line with several arguments which have to answer two questions: What should be compiled? What should the output be? To answer the first question, it is usually sufficient to provide a class path via the -p <path> argument, along with the main class to be compiled via the -m <dot_path> argument. The Haxe Compiler then resolves the main class file and begins compilation. The second question usually comes down to providing an argument specifying the desired target. Each Haxe target has a dedicated command line switch, such as --js <file_name> for JavaScript and --php <directory> for PHP. Depending on the nature of the target, the argument value is either a directory path (for --php , --cpp , --cs , and --java ) or a file name. Common arguments Input: -p <path> (or --class-path <path> ) Add a class path where .hx source files or packages (sub-directories) can be found. -L <library_name> (or --library <library_name> ) Add a Haxelib library. By default the most recent version in the local Haxelib repository is used. To require a specific library version use -L library_name:version . To require a version from git use -L library_name:git:https://github.com/user/project.git#commit where the optional #commit can be a branch, tag or commit hash. -m <dot_path> (or --main <dot_path> ) Set the main class. -D <var[=value]> (or --define <var[=value]> ) Define a conditional compilation flag . Output: --js <file_name.js> Generate JavaScript source code in specified file. --swf <file_name.swf> Generate the specified file as Flash .swf . --neko <file_name.n> Generate Neko binary as specified file. --php <directory> Generate PHP source code in specified directory. Use -D php7 for PHP7 source code. --cpp <directory> Generate C++ source code in specified directory and compiles it using native C++ compiler. --cs <directory> Generate C# source code in specified directory and compiles it using native C# compiler. --java <directory> Generate Java source code in specified directory and compiles it using the Java Compiler. Add -D jvm to generate JVM byte code directly bypassing Java compilation step. --jvm <file_name.jar> Generate JVM bytecode as a jar file. --python <file_name.py> Generate Python source code in the specified file. --lua <file_name.lua> Generate Lua source code in the specified file. --hl <file_name.hl> Generate HashLink byte code in specified file. --cppia <file_name.cppia> Generate the specified script as a cppia file. -x <file> Shortcut for compiling and executing a Neko file. --no-output Compile but do not generate any file. --interp Interpret the program using internal macro system. Other global arguments --run <module> [args...] Compile and execute a Haxe module with command line arguments. --xml <file> Generate XML types description. Useful for API documentation generation tools like Dox . --json <file> Generate JSON types description. -v (or --verbose ) Turn on verbose mode. --dce <std\|full\|no> Set the Dead Code Elimination mode (default std ). --debug Add debug information to the compiled code. -r <file>[@name] (or --resource <file>[@name] ) Add a named resource file. --prompt Prompt on error. --cmd <command> Run the specified shell command after a successful compilation. --no-traces Don't compile trace calls in the program. --display Display code tips to provide completion information for IDEs and editors . --times Measure compilation times. --no-inline Disable inlining . --no-opt Disable code optimizations. --remap <package:target> Remap a package to another one. --macro Call the given initialization macro before typing anything else. --wait <host:port> Wait on the given port for commands to run (see Completion server ). --connect <host:port> Connect on the given port and run commands there (see Completion server ). -C <dir> (or --cwd <dir> ) Set current working directory. Target specific arguments -D php-front=<filename> Select the name for the php front file. -D php-lib=<filename> Select the name for the php lib folder. -D php-prefix=<name> Prefix all classes with given name. --swf-version <version> Change the SWF version. --swf-header <header> Define SWF header (width:height:fps:color). --swf-lib <file> Add the SWF library to the compiled SWF. --swf-lib-extern <file> Use the SWF library for type checking. --flash-strict More type strict flash API. --java-lib <file> Add an external JAR or class directory library. --net-lib <file>[@std] Add an external .NET DLL file. --net-std <file> Add a root std .NET DLL search path. --c-arg <arg> Pass option arg to the native Java/C# compiler. Trivia: Run commands after compilation Use --cmd to run the specified command after a successful compilation. It can be used to run (testing) tools or to directly run the build, e.g. --cmd java -jar bin/Main.jar (for Java), --cmd node main.js (for Node.js) or --cmd neko Main.n (for Neko) etc. Global compiler configuration macros: In order to include single modules, their paths can be listed directly on command line or in hxml: haxe ... ModuleName pack.ModuleName . For more specific includes or excludes, use these initialization macros : --macro include(pack:String, recursive=true, ?ignore:Array<String>, ?classPaths:Array<String>, strict=false) Includes all modules in package pack in the compilation. If recursive is true, the compiler recursively adds all sub-packages. --macro exclude(pack:String, recursive=true Exclude a specific class, enum, or all classes and enums in a package from being generated. Excluded types become extern . If recursive is true, the compiler recursively excludes all sub-packages. --macro excludeFile(fileName:String) Exclude classes and enums listed from given external file (one per line) from being generated. --macro keep(?path:String, ?paths:Array<String>, recursive=true) Marks a package, module or sub-type dot path to be kept by DCE. This also extends to the sub-types of resolved modules. If recursive is true, the compiler recursively keeps all sub-packages for package paths. --macro includeFile(file:String, position) Embed a JavaScript file at compile time. position can be either "top", "inline" or "closure". The full documentation of these methods can be found in the haxe.macro.Compiler API documentation.

What should be compiled? - What should the output be? To answer the first question, it is usually sufficient to provide a class path via the `-p <path>` argument, along with the main class to be compiled via the `-m <dot_path>` argument. The Haxe Compiler then resolves the main class file and begins compilation. The second question usually comes down to providing an argument specifying the desired target. Each Haxe target has a dedicated command line switch, such as `--js <file_name>` for JavaScript and `--php <directory>` for PHP. Depending on the nature of the target, the argument value is either a directory path (for `--php`, `--cpp`, `--cs`, and `--java`) or a file name. ##### [Common arguments](https://haxe.org/manual/compiler-usage.html#common-arguments) Input: - `-p <path>` (or `--class-path <path>`) Add a class path where `.hx` source files or packages (sub-directories) can be found. - `-L <library_name>` (or `--library <library_name>`) Add a [Haxelib](https://haxe.org/manual/haxelib.html) library. By default the most recent version in the local Haxelib repository is used. To require a specific library version use `-L library_name:version`. To require a version from git use `-L library_name:git:https://github.com/user/project.git#commit` where the optional \#commit can be a branch, tag or commit hash. - `-m <dot_path>` (or `--main <dot_path>`) Set the main class. - `-D <var[=value]>` (or `--define <var[=value]>`) Define a [conditional compilation flag](https://haxe.org/manual/lf-condition-compilation.html). Output: - `--js <file_name.js>` Generate [JavaScript](https://haxe.org/manual/target-javascript.html) source code in specified file. - `--swf <file_name.swf>` Generate the specified file as [Flash](https://haxe.org/manual/target-flash.html) `.swf`. - `--neko <file_name.n>` Generate [Neko](https://haxe.org/manual/target-neko.html) binary as specified file. - `--php <directory>` Generate [PHP](https://haxe.org/manual/target-php.html) source code in specified directory. Use `-D php7` for PHP7 source code. - `--cpp <directory>` Generate [C++](https://haxe.org/manual/target-cpp.html) source code in specified directory and compiles it using native C++ compiler. - `--cs <directory>` Generate [C\#](https://haxe.org/manual/target-cs.html) source code in specified directory and compiles it using native C\# compiler. - `--java <directory>` Generate [Java](https://haxe.org/manual/target-java.html) source code in specified directory and compiles it using the Java Compiler. Add `-D jvm` to generate JVM byte code directly bypassing Java compilation step. - `--jvm <file_name.jar>` Generate [JVM bytecode](https://haxe.org/manual/target-jvm.html) as a jar file. - `--python <file_name.py>` Generate [Python](https://haxe.org/manual/target-python.html) source code in the specified file. - `--lua <file_name.lua>` Generate [Lua](https://haxe.org/manual/target-lua.html) source code in the specified file. - `--hl <file_name.hl>` Generate [HashLink](https://haxe.org/manual/target-hl.html) byte code in specified file. - `--cppia <file_name.cppia>` Generate the specified script as a [cppia](https://haxe.org/manual/target-cppia.html) file. - `-x <file>` Shortcut for compiling and executing a Neko file. - `--no-output` Compile but do not generate any file. - `--interp` Interpret the program using internal macro system. ##### [Other global arguments](https://haxe.org/manual/compiler-usage.html#other-global-arguments) - `--run <module> [args...]` Compile and execute a Haxe module with command line arguments. - `--xml <file>` Generate XML types description. Useful for API documentation generation tools like [Dox](https://github.com/HaxeFoundation/dox). - `--json <file>` Generate JSON types description. - `-v` (or `--verbose`) Turn on verbose mode. - `--dce <std\|full\|no>` Set the [Dead Code Elimination](https://haxe.org/manual/cr-dce.html) mode (default `std`). - `--debug` Add debug information to the compiled code. - `-r <file>[@name]` (or `--resource <file>[@name]`) Add a named resource file. - `--prompt` Prompt on error. - `--cmd <command>` Run the specified shell command after a successful compilation. - `--no-traces` Don't compile trace calls in the program. - `--display` Display code tips to provide [completion information for IDEs and editors](https://haxe.org/manual/cr-completion-overview.html). - `--times` Measure compilation times. - `--no-inline` Disable [inlining](https://haxe.org/manual/class-field-inline.html). - `--no-opt` Disable code optimizations. - `--remap <package:target>` Remap a package to another one. - `--macro` Call the given [initialization macro](https://haxe.org/manual/macro-initialization.html) before typing anything else. - `--wait <host:port>` Wait on the given port for commands to run (see [Completion server](https://haxe.org/manual/cr-completion-server.html)). - `--connect <host:port>` Connect on the given port and run commands there (see [Completion server](https://haxe.org/manual/cr-completion-server.html)). - `-C <dir>` (or `--cwd <dir>`) Set current working directory. ##### [Target specific arguments](https://haxe.org/manual/compiler-usage.html#target-specific-arguments) - `-D php-front=<filename>` Select the name for the php front file. - `-D php-lib=<filename>` Select the name for the php lib folder. - `-D php-prefix=<name>` Prefix all classes with given name. - `--swf-version <version>` Change the SWF version. - `--swf-header <header>` Define SWF header (width:height:fps:color). - `--swf-lib <file>` Add the SWF library to the compiled SWF. - `--swf-lib-extern <file>` Use the SWF library for type checking. - `--flash-strict` More type strict flash API. - `--java-lib <file>` Add an external JAR or class directory library. - `--net-lib <file>[@std]` Add an external .NET DLL file. - `--net-std <file>` Add a root std .NET DLL search path. - `--c-arg <arg>` Pass option `arg` to the native Java/C\# compiler. > ##### [Trivia: Run commands after compilation](https://haxe.org/manual/compiler-usage.html#trivia-run-commands-after-compilation) > Use `--cmd` to run the specified command after a successful compilation. It can be used to run (testing) tools or to directly run the build, e.g. `--cmd java -jar bin/Main.jar` (for Java), `--cmd node main.js` (for Node.js) or `--cmd neko Main.n` (for Neko) etc. ##### [Global compiler configuration macros:](https://haxe.org/manual/compiler-usage.html#global-compiler-configuration-macros) In order to include single modules, their paths can be listed directly on command line or in hxml: `haxe ... ModuleName pack.ModuleName`. For more specific includes or excludes, use these [initialization macros](https://haxe.org/manual/macro-initialization.html): - `--macro include(pack:String, recursive=true, ?ignore:Array<String>, ?classPaths:Array<String>, strict=false)` Includes all modules in package pack in the compilation. If `recursive` is true, the compiler recursively adds all sub-packages. - `--macro exclude(pack:String, recursive=true` Exclude a specific class, enum, or all classes and enums in a package from being generated. Excluded types become `extern`. If `recursive` is true, the compiler recursively excludes all sub-packages. - `--macro excludeFile(fileName:String)` Exclude classes and enums listed from given external file (one per line) from being generated. - `--macro keep(?path:String, ?paths:Array<String>, recursive=true)` Marks a package, module or sub-type dot path to be kept by DCE. This also extends to the sub-types of resolved modules. If `recursive` is true, the compiler recursively keeps all sub-packages for package paths. - `--macro includeFile(file:String, position)` Embed a JavaScript file at compile time. `position` can be either "top", "inline" or "closure". The full documentation of these methods can be found in the [`haxe.macro.Compiler`](http://api.haxe.org/haxe/macro/Compiler.html) API documentation. ##### [Help](https://haxe.org/manual/compiler-usage.html#help) - `haxe --version` Print the current Haxe compiler version. - `haxe --help` Display this list of options. - `haxe --help-defines` Print help for all [compiler specific defines](https://haxe.org/manual/compiler-usage-flags.html). - `haxe --help-metas` Print help for all [compiler metadata](https://haxe.org/manual/lf-condition-compilation.html). ##### [Related content](https://haxe.org/manual/compiler-usage.html#related-content) - [Compilation tutorials](http://code.haxe.org/category/compilation/) in the Haxe Code Cookbook.
