# nuitka 1.6.1 --help ``` text Usage: __main__.py [--module] [--run] [options] main_module.py Options: --help show this help message and exit --version Show version information and important details for bug reports, then exit. Defaults to off. --module Create an extension module executable instead of a program. Defaults to off. --standalone Enable standalone mode for output. This allows you to transfer the created binary to other machines without it using an existing Python installation. This also means it will become big. It implies these option: "-- follow-imports" and "--python-flag=no_site". Defaults to off. --onefile On top of standalone mode, enable onefile mode. This means not a folder, but a compressed executable is created and used. Defaults to off. --python-debug Use debug version or not. Default uses what you are using to run Nuitka, most likely a non-debug version. --python-flag=FLAG Python flags to use. Default is what you are using to run Nuitka, this enforces a specific mode. These are options that also exist to standard Python executable. Currently supported: "-S" (alias "no_site"), "static_hashes" (do not use hash randomization), "no_warnings" (do not give Python run time warnings), "-O" (alias "no_asserts"), "no_docstrings" (do not use doc strings), "-u" (alias "unbuffered") and "-m". Default empty. --python-for-scons=PATH If using Python3.3 or Python3.4, provide the path of a Python binary to use for Scons. Otherwise Nuitka can use what you run Nuitka with or a Python installation from Windows registry. On Windows Python 3.5 or higher is needed. On non-Windows, Python 2.6 or 2.7 will do as well. Control the inclusion of modules and packages in result: --include-package=PACKAGE Include a whole package. Give as a Python namespace, e.g. "some_package.sub_package" and Nuitka will then find it and include it and all the modules found below that disk location in the binary or extension module it creates, and make it available for import by the code. To avoid unwanted sub packages, e.g. tests you can e.g. do this "--nofollow-import-to=*.tests". Default empty. --include-module=MODULE Include a single module. Give as a Python namespace, e.g. "some_package.some_module" and Nuitka will then find it and include it in the binary or extension module it creates, and make it available for import by the code. Default empty. --include-plugin-directory=MODULE/PACKAGE Include also the code found in that directory, considering as if they are each given as a main file. Overrides all other inclusion options. You ought to prefer other inclusion options, that go by names, rather than filenames, those find things through being in "sys.path". This option is for very special use cases only. Can be given multiple times. Default empty. --include-plugin-files=PATTERN Include into files matching the PATTERN. Overrides all other follow options. Can be given multiple times. Default empty. --prefer-source-code For already compiled extension modules, where there is both a source file and an extension module, normally the extension module is used, but it should be better to compile the module from available source code for best performance. If not desired, there is --no- prefer-source-code to disable warnings about it. Default off. Control the following into imported modules: --follow-imports Descend into all imported modules. Defaults to on in standalone mode, otherwise off. --follow-import-to=MODULE/PACKAGE Follow to that module if used, or if a package, to the whole package. Can be given multiple times. Default empty. --nofollow-import-to=MODULE/PACKAGE Do not follow to that module name even if used, or if a package name, to the whole package in any case, overrides all other options. Can be given multiple times. Default empty. --nofollow-imports Do not descend into any imported modules at all, overrides all other inclusion options and not usable for standalone mode. Defaults to off. --follow-stdlib Also descend into imported modules from standard library. This will increase the compilation time by a lot and is also not well tested at this time and sometimes won't work. Defaults to off. Onefile options: --onefile-tempdir-spec=ONEFILE_TEMPDIR_SPEC Use this as a folder to unpack to in onefile mode. Defaults to '%TEMP%/onefile_%PID%_%TIME%', i.e. user temporary directory and being non-static it's removed. Use e.g. a string like '%CACHE_DIR%/%COMPANY%/%PRODUCT%/%VERSION%' which is a good static cache path, this will then not be removed. --onefile-child-grace-time=GRACE_TIME_MS When stopping the child, e.g. due to CTRL-C or shutdown, etc. the Python code gets a "KeyboardInterrupt", that it may handle e.g. to flush data. This is the amount of time in ms, before the child it killed in the hard way. Unit is ms, and default 5000. --onefile-no-compression When creating the onefile, disable compression of the payload. This is mostly for debug purposes, or to save time. Default is off. Data files: --include-package-data=PACKAGE Include data files for the given package name. DLLs and extension modules are not data files and never included like this. Can use patterns the filenames as indicated below. Data files of packages are not included by default, but package configuration can do it. This will only include non-DLL, non-extension modules, i.e. actual data files. After a ":" optionally a filename pattern can be given as well, selecting only matching files. Examples: "--include- package-data=package_name" (all files) "--include- package-data=package_name=*.txt" (only certain type) " --include-package-data=package_name=some_filename.dat (concrete file) Default empty. --include-data-files=DESC Include data files by filenames in the distribution. There are many allowed forms. With '--include-data- files=/path/to/file/*.txt=folder_name/some.txt' it will copy a single file and complain if it's multiple. With '--include-data- files=/path/to/files/*.txt=folder_name/' it will put all matching files into that folder. For recursive copy there is a form with 3 values that '--include- data-files=/path/to/scan=folder_name=**/*.txt' that will preserve directory structure. Default empty. --include-data-dir=DIRECTORY Include data files from complete directory in the distribution. This is recursive. Check '--include- data-files' with patterns if you want non-recursive inclusion. An example would be '--include-data- dir=/path/some_dir=data/some_dir' for plain copy, of the whole directory. All files are copied, if you want to exclude files you need to remove them beforehand, or use '--noinclude-data-files' option to remove them. Default empty. --noinclude-data-files=PATTERN Do not include data files matching the filename pattern given. This is against the target filename, not source paths. So to ignore a file pattern from package data for "package_name" should be matched as "package_name/*.txt". Or for the whole directory simply use "package_name". Default empty. --list-package-data=LIST_PACKAGE_DATA Output the data files found for a given package name. Default not done. Metadata support: --include-distribution-metadata=DISTRIBUTION Include metadata information for the given distribution name. Some packages check metadata for presence, version, entry points, etc. and without this option given, it only works when it's recognized at compile time which is not always happening. This of course only makes sense for packages that are included in the compilation. Default empty. DLL files: --noinclude-dlls=PATTERN Do not include DLL files matching the filename pattern given. This is against the target filename, not source paths. So ignore a DLL "someDLL" contained in the package "package_name" it should be matched as "package_name/someDLL.*". Default empty. --list-package-dlls=LIST_PACKAGE_DLLS Output the DLLs found for a given package name. Default not done. Control the warnings to be given by Nuitka: --warn-implicit-exceptions Enable warnings for implicit exceptions detected at compile time. --warn-unusual-code Enable warnings for unusual code detected at compile time. --assume-yes-for-downloads Allow Nuitka to download external code if necessary, e.g. dependency walker, ccache, and even gcc on Windows. To disable, redirect input from nul device, e.g. "" is used. For compatibility reasons, the "__file__" value will always have ".py" suffix independent of what it really is. --module-name-choice=MODE Select what value "__name__" and "__package__" are going to be. With "runtime" (default for module mode), the created module uses the parent package to deduce the value of "__package__", to be fully compatible. The value "original" (default for other modes) allows for more static optimization to happen, but is incompatible for modules that normally can be loaded into any package. Output choices: --output-filename=FILENAME Specify how the executable should be named. For extension modules there is no choice, also not for standalone mode and using it will be an error. This may include path information that needs to exist though. Defaults to '' on this platform. .exe --output-dir=DIRECTORY Specify where intermediate and final output files should be put. The DIRECTORY will be populated with build folder, dist folder, binaries, etc. Defaults to current directory. --remove-output Removes the build directory after producing the module or exe file. Defaults to off. --no-pyi-file Do not create a ".pyi" file for extension modules created by Nuitka. This is used to detect implicit imports. Defaults to off. Debug features: --debug Executing all self checks possible to find errors in Nuitka, do not use for production. Defaults to off. --unstripped Keep debug info in the resulting object file for better debugger interaction. Defaults to off. --profile Enable vmprof based profiling of time spent. Not working currently. Defaults to off. --internal-graph Create graph of optimization process internals, do not use for whole programs, but only for small test cases. Defaults to off. --trace-execution Traced execution output, output the line of code before executing it. Defaults to off. --recompile-c-only This is not incremental compilation, but for Nuitka development only. Takes existing files and simply compile them as C again. Allows compiling edited C files for quick debugging changes to the generated source, e.g. to see if code is passed by, values output, etc, Defaults to off. Depends on compiling Python source to determine which files it should look at. --xml=XML_FILENAME Write the internal program structure, result of optimization in XML form to given filename. --generate-c-only Generate only C source code, and do not compile it to binary or module. This is for debugging and code coverage analysis that doesn't waste CPU. Defaults to off. Do not think you can use this directly. --experimental=FLAG Use features declared as 'experimental'. May have no effect if no experimental features are present in the code. Uses secret tags (check source) per experimented feature. --low-memory Attempt to use less memory, by forking less C compilation jobs and using options that use less memory. For use on embedded machines. Use this in case of out of memory problems. Defaults to off. --create-environment-from-report=CREATE_ENVIRONMENT_FROM_REPORT Create a new virtualenv in that non-existing path from the report file given with e.g. '--report=compilation- report.xml'. Default not done. Backend C compiler choice: --clang Enforce the use of clang. On Windows this requires a working Visual Studio version to piggy back on. Defaults to off. --mingw64 Enforce the use of MinGW64 on Windows. Defaults to off unless MSYS2 with MinGW Python is used. --msvc=MSVC_VERSION Enforce the use of specific MSVC version on Windows. Allowed values are e.g. "14.3" (MSVC 2022) and other MSVC version numbers, specify "list" for a list of installed compilers, or use "latest". Defaults to latest MSVC being used if installed, otherwise MinGW64 is used. --jobs=N Specify the allowed number of parallel C compiler jobs. Defaults to the system CPU count. --lto=choice Use link time optimizations (MSVC, gcc, clang). Allowed values are "yes", "no", and "auto" (when it's known to work). Defaults to "auto". --static-libpython=choice Use static link library of Python. Allowed values are "yes", "no", and "auto" (when it's known to work). Defaults to "auto". Cache Control: --disable-cache=DISABLED_CACHES Disable selected caches, specify "all" for all cached. Currently allowed values are: "all","ccache","bytecode","dll-dependencies". can be given multiple times or with comma separated values. Default none. --clean-cache=CLEAN_CACHES Clean the given caches before executing, specify "all" for all cached. Currently allowed values are: "all","ccache","bytecode","dll-dependencies". can be given multiple times or with comma separated values. Default none. --disable-bytecode-cache Do not reuse dependency analysis results for modules, esp. from standard library, that are included as bytecode. Same as --disable-cache=bytecode. --disable-ccache Do not attempt to use ccache (gcc, clang, etc.) or clcache (MSVC, clangcl). Same as --disable- cache=ccache. --disable-dll-dependency-cache Disable the dependency walker cache. Will result in much longer times to create the distribution folder, but might be used in case the cache is suspect to cause errors. Same as --disable-cache=dll- dependencies. --force-dll-dependency-cache-update For an update of the dependency walker cache. Will result in much longer times to create the distribution folder, but might be used in case the cache is suspect to cause errors or known to need an update. PGO compilation choices: --pgo Enables C level profile guided optimization (PGO), by executing a dedicated build first for a profiling run, and then using the result to feedback into the C compilation. Note: This is experimental and not working with standalone modes of Nuitka yet. Defaults to off. --pgo-args=PGO_ARGS Arguments to be passed in case of profile guided optimization. These are passed to the special built executable during the PGO profiling run. Default empty. --pgo-executable=PGO_EXECUTABLE Command to execute when collecting profile information. Use this only, if you need to launch it through a script that prepares it to run. Default use created program. Tracing features: --report=REPORT_FILENAME Report module, data files, compilation, plugin, etc. details in an XML output file. This is also super useful for issue reporting. These reports can e.g. be used to re-create the environment easily using it with '--create-environment-from-report', but contain a lot of information. Default is off. --report-diffable Report data in diffable form, i.e. no timing or memory usage values that vary from run to run. Default is off. --report-user-provided=KEY_VALUE Report data from you. This can be given multiple times and be anything in 'key=value' form, where key should be an identifier, e.g. use '--report-user- provided=pipenv-lock-hash=64a5e4' to track some input values. Default is empty. --report-template=REPORT_DESC Report via template. Provide template and output filename "template.rst.j2:output.rst". For built-in templates, check the User Manual for what these are. Can be given multiple times. Default is empty. --quiet Disable all information outputs, but show warnings. Defaults to off. --show-scons Run the C building backend Scons with verbose information, showing the executed commands, detected compilers. Defaults to off. --no-progressbar Disable progress bars. Defaults to off. --show-progress Obsolete: Provide progress information and statistics. Disables normal progress bar. Defaults to off. --show-memory Provide memory information and statistics. Defaults to off. --show-modules Provide information for included modules and DLLs Obsolete: You should use '--report' file instead. Defaults to off. --show-modules-output=PATH Where to output '--show-modules', should be a filename. Default is standard output. --verbose Output details of actions taken, esp. in optimizations. Can become a lot. Defaults to off. --verbose-output=PATH Where to output from '--verbose', should be a filename. Default is standard output. General OS controls: --disable-console When compiling for Windows or macOS, disable the console window and create a GUI application. Defaults to off. --enable-console When compiling for Windows or macOS, enable the console window and create a console application. This disables hints from certain modules, e.g. "PySide" that suggest to disable it. Defaults to true. --force-stdout-spec=FORCE_STDOUT_SPEC Force standard output of the program to go to this location. Useful for programs with disabled console and programs using the Windows Services Plugin of Nuitka commercial. Defaults to not active, use e.g. '%PROGRAM%.out.txt', i.e. file near your program, check User Manual for full list of available values. --force-stderr-spec=FORCE_STDERR_SPEC Force standard error of the program to go to this location. Useful for programs with disabled console and programs using the Windows Services Plugin of Nuitka commercial. Defaults to not active, use e.g. '%PROGRAM%.err.txt', i.e. file near your program, check User Manual for full list of available values. Windows specific controls: --windows-icon-from-ico=ICON_PATH Add executable icon. Can be given multiple times for different resolutions or files with multiple icons inside. In the later case, you may also suffix with # where n is an integer index starting from 1, specifying a specific icon to be included, and all others to be ignored. --windows-icon-from-exe=ICON_EXE_PATH Copy executable icons from this existing executable (Windows only). --onefile-windows-splash-screen-image=SPLASH_SCREEN_IMAGE When compiling for Windows and onefile, show this while loading the application. Defaults to off. --windows-uac-admin Request Windows User Control, to grant admin rights on execution. (Windows only). Defaults to off. --windows-uac-uiaccess Request Windows User Control, to enforce running from a few folders only, remote desktop access. (Windows only). Defaults to off. macOS specific controls: --macos-target-arch=MACOS_TARGET_ARCH What architectures is this to supposed to run on. Default and limit is what the running Python allows for. Default is "native" which is the architecture the Python is run with. --macos-create-app-bundle When compiling for macOS, create a bundle rather than a plain binary application. Currently experimental and incomplete. Currently this is the only way to unlock disabling of console.Defaults to off. --macos-app-icon=ICON_PATH Add icon for the application bundle to use. Can be given only one time. Defaults to Python icon if available. --macos-signed-app-name=MACOS_SIGNED_APP_NAME Name of the application to use for macOS signing. Follow "com.YourCompany.AppName" naming results for best results, as these have to be globally unique, and will potentially grant protected API accesses. --macos-app-name=MACOS_APP_NAME Name of the product to use in macOS bundle information. Defaults to base filename of the binary. --macos-app-mode=MODE Mode of application for the application bundle. When launching a Window, and appearing in Docker is desired, default value "gui" is a good fit. Without a Window ever, the application is a "background" application. For UI elements that get to display later, "ui-element" is in-between. The application will not appear in dock, but get full access to desktop when it does open a Window later. --macos-sign-identity=MACOS_APP_VERSION When signing on macOS, by default an ad-hoc identify will be used, but with this option your get to specify another identity to use. The signing of code is now mandatory on macOS and cannot be disabled. Default "ad-hoc" if not given. --macos-sign-notarization When signing for notarization, using a proper TeamID identity from Apple, use the required runtime signing option, such that it can be accepted. --macos-app-version=MACOS_APP_VERSION Product version to use in macOS bundle information. Defaults to "1.0" if not given. --macos-app-protected-resource=RESOURCE_DESC Request an entitlement for access to a macOS protected resources, e.g. "NSMicrophoneUsageDescription:Microphone access for recording audio." requests access to the microphone and provides an informative text for the user, why that is needed. Before the colon, is an OS identifier for an access right, then the informative text. Legal values can be found on https://developer.apple.com/doc umentation/bundleresources/information_property_list/p rotected_resources and the option can be specified multiple times. Default empty. Linux specific controls: --linux-icon=ICON_PATH Add executable icon for onefile binary to use. Can be given only one time. Defaults to Python icon if available. Binary Version Information: --company-name=COMPANY_NAME Name of the company to use in version information. Defaults to unused. --product-name=PRODUCT_NAME Name of the product to use in version information. Defaults to base filename of the binary. --file-version=FILE_VERSION File version to use in version information. Must be a sequence of up to 4 numbers, e.g. 1.0 or 1.0.0.0, no more digits are allowed, no strings are allowed. Defaults to unused. --product-version=PRODUCT_VERSION Product version to use in version information. Same rules as for file version. Defaults to unused. --file-description=FILE_DESCRIPTION Description of the file used in version information. Windows only at this time. Defaults to binary filename. --copyright=COPYRIGHT_TEXT Copyright used in version information. Windows only at this time. Defaults to not present. --trademarks=TRADEMARK_TEXT Copyright used in version information. Windows only at this time. Defaults to not present. Plugin control: --enable-plugin=PLUGIN_NAME Enabled plugins. Must be plug-in names. Use '--plugin- list' to query the full list and exit. Default empty. --disable-plugin=PLUGIN_NAME Disabled plugins. Must be plug-in names. Use '-- plugin-list' to query the full list and exit. Most standard plugins are not a good idea to disable. Default empty. --plugin-no-detection Plugins can detect if they might be used, and the you can disable the warning via "--disable-plugin=plugin- that-warned", or you can use this option to disable the mechanism entirely, which also speeds up compilation slightly of course as this detection code is run in vain once you are certain of which plugins to use. Defaults to off. --plugin-list Show list of all available plugins and exit. Defaults to off. --user-plugin=PATH The file name of user plugin. Can be given multiple times. Default empty. --show-source-changes Show source changes to original Python file content before compilation. Mostly intended for developing plugins. Default False. Plugin options of 'anti-bloat': --show-anti-bloat-changes Annotate what changes are by the plugin done. --noinclude-setuptools-mode=NOINCLUDE_SETUPTOOLS_MODE What to do if a 'setuptools' or import is encountered. This package can be big with dependencies, and should definitely be avoided. Also handles 'setuptools_scm'. --noinclude-pytest-mode=NOINCLUDE_PYTEST_MODE What to do if a 'pytest' import is encountered. This package can be big with dependencies, and should definitely be avoided. Also handles 'nose' imports. --noinclude-unittest-mode=NOINCLUDE_UNITTEST_MODE What to do if a unittest import is encountered. This package can be big with dependencies, and should definitely be avoided. --noinclude-IPython-mode=NOINCLUDE_IPYTHON_MODE What to do if a IPython import is encountered. This package can be big with dependencies, and should definitely be avoided. --noinclude-dask-mode=NOINCLUDE_DASK_MODE What to do if a 'dask' import is encountered. This package can be big with dependencies, and should definitely be avoided. --noinclude-numba-mode=NOINCLUDE_NUMBA_MODE What to do if a 'numba' import is encountered. This package can be big with dependencies, and is currently not working for standalone. This package is big with dependencies, and should definitely be avoided. --noinclude-default-mode=NOINCLUDE_DEFAULT_MODE This actually provides the default "warning" value for above options, and can be used to turn all of these on. --noinclude-custom-mode=CUSTOM_CHOICES What to do if a specific import is encountered. Format is module name, which can and should be a top level package and then one choice, "error", "warning", "nofollow", e.g. PyQt5:error. ```
