NAME
nuitka-run - the Python compiler
SYNOPSIS
nuitka-run [options] main_module.py
OPTIONS
--version
show program's version number and exit
-h, --help
show this help message and exit
--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". You may also want to use "--pythonflag=no_site" to
avoid the "site.py" module, which can save a lot of code dependencies. 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
runtime warnings), "-O" (alias "no_asserts"), "no_docstrings" (do not use docstrings), 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 "scons" binary that is found in PATH, or a Python
installation from Windows registry.
--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. "</dev/null" or "<NUL:". Default is
to prompt.
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 the content of that directory, no matter if it's used by the given main program in a
visible form. Overrides all other inclusion options. 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 --noprefer-source-code to
disable warnings about it. Default off.
Control the following into imported modules:
--follow-stdlib
Also descend into imported modules from standard library. This will increase the compilation time
by a lot. Defaults to off.
--nofollow-imports
When --nofollow-imports is used, do not descend into any imported modules at all, overrides all
other inclusion options. Defaults to off.
--follow-imports
When --follow-imports is used, attempt to descend into all imported modules. Defaults to 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.
Data files for standalone/onefile mode:
--include-package-data=PACKAGE
Include data files of the given package name. Can use patterns. By default Nuitka does not unless
hard coded and vital for operation of a package. This will include all non-DLL, non-extension
modules in the distribution. Default empty.
--include-data-file=DESC
Include data files by filenames in the distribution. There are many allowed forms. With
'--include-datafile=/path/to/file/*.txt=folder_name/some.txt' it will copy a single file and
complain if it's multiple. With '--include-datafile=/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
'--includedata-file=/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
'--includedata-file' with patterns if you want non-recursive inclusion. An example would be
'--include-datadir=/path/somedir=data/somedir' for plain copy, of the whole directory. All files
are copied, if you want to exclude files you need to remove them beforehand. Default empty.
Immediate execution after compilation:
--run Execute immediately the created binary (or import the compiled module). Defaults to on.
--debugger, --gdb
Execute inside a debugger, e.g. "gdb" or "lldb" to automatically get a stack trace. Defaults to
off.
--execute-with-pythonpath
When immediately executing the created binary (--execute), don't reset PYTHONPATH. When all
modules are successfully included, you ought to not need PYTHONPATH anymore.
Dump options for internal tree:
--xml Dump the final result of optimization as XML, then exit.
Code generation choices:
--full-compat
Enforce absolute compatibility with CPython. Do not even allow minor deviations from CPython
behavior, e.g. not having better tracebacks or exception messages which are not really
incompatible, but only different. This is intended for tests only and should not be used for
normal use.
--file-reference-choice=MODE
Select what value "__file__" is going to be. With "runtime" (default for standalone binary mode
and module mode), the created binaries and modules, use the location of themselves to deduct the
value of "__file__". Included packages pretend to be in directories below that location. This
allows you to include data files in deployments. If you merely seek acceleration, it's better for
you to use the "original" value, where the source files location will be used. With "frozen" a
notation "<frozen module_name>" is used. For compatibility reasons, the "__file__" value will
always have ".py" suffix independent of what it really is.
Output choices:
-o 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 '<program_name>' on this platform. .bin
--output-dir=DIRECTORY
Specify where intermediate and final output files should be put. The DIRECTORY will be populated
with C files, object files, 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.
--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.
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.
--msvc=MSVC_VERSION
Enforce the use of specific MSVC version on Windows. Allowed values are e.g. "14.2" (MSVC 2019),
specify an illegal value for a list of installed compilers, or use "latest". Notice that only
latest MSVC is really supported, and you can use "latest" to enforce that. Defaults to MSVC on
Windows being used if installed, otherwise MinGW64.
-j N, --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".
--disable-ccache
Do not attempt to use ccache (gcc, clang, etc.) or clcache (MSVC, clangcl).
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:
--quiet
Disable all information outputs, but show warnings. Defaults to off.
--show-scons
Operate Scons in non-quiet mode, showing the executed commands. Defaults to off.
--show-progress

Description of the file use in Windows Version information. One of file or product version is
required, when a version resource needs to be added, e.g. to specify product name, or company
name. Defaults to nonsense.
--windows-onefile-tempdir-spec=ONEFILE_TEMPDIR_SPEC
Use this as a temporary folder. Defaults to '%TEMP%\onefile_%PID%_%TIME%', i.e. system temporary
directory.
--windows-force-stdout-spec=WINDOWS_FORCE_STDOUT_SPEC

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-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 grant protected API accesses.

empty.
--plugin-no-detection
Plugins can detect if they might be used, and the you can disable the warning via
"--disable-plugin=pluginthat-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.

EXAMPLES
Compile a Python file "some_module.py" to a module "some_module.so":
$ nuitka --module some_module.py
Compile a Python program "some_program.py" to an executable "some_program.exe":
$ nuitka some_program.py
Compile a Python program "some_program.py" and the package "some_package" it uses to an executable
"some_program.exe":
$ nuitka --recurse-to=some_package some_program.py
Compile a Python program "some_program.py" and all the modules it uses to an executable
"some_program.exe". Then execute it immediately when ready:
$ nuitka --run --recurse-all some_program.py
Compile a Python program "some_program.py" and the modules it uses (even standard library) to an
executable "some_program.exe":
$ nuitka --recurse-all --recurse-stdlib some_program.py
Compile a Python program "some_program.py" and the modules it uses to an executable "some_program.exe".
Keep the debug information, so valgrind, gdb, etc. work nicely.
Note: This will *not* degrade performance:
$ nuitka --unstriped --recurse-all some_program.py
Compile a Python program "some_program.py" and the modules it uses to an executable "some_program.exe".
Perform all kinds of checks about correctness of the generated C and run-time checks.
Note: This will degrade performance and should only be used to debug Nuitka:
$ nuitka --debug --recurse-all some_program.py
Compile a Python program "some_program.py" and the modules it uses to an executable "some_program.exe".
Perform all kinds of checks about correctness of the generated C and run-time checks. Also use the debug
Python library, which does its own checks.
Note: This will degrade performance and should only be used to debug Nuitka:
$ nuitka --debug --python-debug --recurse-all some_program.py
Compile a Python program "some_program.py" and the plugins modules it loads at run time to an executable
"some_program.exe":
$ nuitka --recurse-all --recurse-directory=plugins_dir some_program.py
