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, --portable
- Enable standalone mode in build. This allows you to transfer the created
binary to other machines without it relying on an existing Python
installation. It implies these options: "--recurse-all
--recursestdlib". You may also want to use
"--pythonflag=no_site" to avoid the "site.py" module.
Defaults to off.
- --nofreeze-stdlib
- In standalone mode by default all modules of standard library will be
frozen as bytecode. This compiles them all and as a result compilation
time will increase very much.
- --python-version=PYTHON_VERSION
- Major version of Python to be used, one of '2.6', '2.7', '3.2', '3.3',
'3.4', or '3.5'. Defaults to what you run Nuitka with (currently 2.7)
- --python-debug, --python-dbg
- Use debug version or not. Default uses what you are using to run Nuitka,
most likely a non-debug version.
- --python-flag=PYTHON_FLAGS
- Python flags to use. Default uses 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
"nosite"), "static_hashes" (not use hash
randomization), "no_warnings" (do not give Python runtime
warnings), "-O" (alias "noasserts"). Default
empty.
- --warn-implicit-exceptions
- Enable warnings for implicit exceptions detected at compile time.
- --warn-unusual-code
- Enable warnings for unusual code detected at compile time.
Control the recursion into imported modules:¶
- --recurse-stdlib
- Also descend into imported modules from standard library. Defaults to
off.
- --recurse-none
- When --recurse-none is used, do not descend into any imported
modules at all, overrides all other recursion options. Defaults to
off.
- --recurse-all, --recurse-on
- When --recurse-all is used, attempt to descend into all imported
modules. Defaults to off.
- --recurse-to=MODULE/PACKAGE
- Recurse to that module, or if a package, to the whole package. Can be
given multiple times. Default empty.
- --recurse-not-to=MODULE/PACKAGE
- Do not recurse to that module, or if a package, to the whole package in
any case, overrides all other options. Can be given multiple times.
Default empty.
- --recurse-plugins=MODULE/PACKAGE,
--recurse-directory=MODULE/PACKAGE
- Recurse into that directory, no matter if it's used by the given main
program in a visible form. Overrides all other recursion options. Can be
given multiple times. Default empty.
- --recurse-files=PATTERN,
--recurse-pattern=PATTERN
- Recurse into files matching the PATTERN. Overrides all recursion other
options. Can be given multiple times. Default empty.
- --run, --execute
- Execute immediately the created binary (or import the compiled module).
Defaults to on.
- --debugger, --gdb
- Execute inside "gdb" to automatically get a stack trace.
Defaults to off.
- --execute-with-pythonpath, --keep-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:¶
- --dump-xml, --xml
- Dump the final result of optimization as XML, then exit.
- --display-tree
- Display the final result of optimization in a GUI, then exit.
Code generation choices:¶
- --full-compat
- Enforce absolute compatibility with CPython. Do not even allow minor
deviations from CPython behavior, e.g. better tracebacks, which are not
really incompatible, but different. This is intended for tests only and
should not be necessary for normal use.
- --file-reference-choice=FILE_REFERENCE_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 directory choices:¶
- --output-dir=DIRECTORY
- Specify where intermediate and final output files should be put. 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.
Debug features:¶
- --debug
- Executing all self checks possible to find errors in Nuitka, do not use
for production. Defaults to off.
- --unstripped, --no-strip, --unstriped
- Keep debug info in the resulting object file for better debugger
interaction. Defaults to off.
- --profile
- Enable vmprof based profiling of time spent. Defaults to off.
- --graph
- Create graph of optimization process. Defaults to off.
- --trace-execution
- Traced execution output, output the line of code before executing it.
Defaults to off.
- --recompile-c++-only, --recompile-c-only
- Take existing files and compile them again.Allows compiling edited C++
files with the C++ compiler for quick debugging changes to the generated
source. 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.
- --experimental
- Use features declared as 'experimental'. May have no effect if no
experimental features are present in the code. Defaults to off.
Backend C++ compiler choice:¶
- --clang
- Enforce the use of clang (needs clang 3.2 or higher). Defaults to
off.
- --mingw
- Enforce the use of MinGW on Windows. Defaults to off.
- --msvc=MSVC
- Enforce the use of specific MSVC version on Windows. Allowed values are
e.g. 9.0, 9.0exp, specify an illegal value for a list of installed
compilers. Defaults to the most recent version.
- -j N, --jobs=N
- Specify the allowed number of parallel C++ compiler jobs. Defaults to the
system CPU count.
- --lto
- Use link time optimizations if available and usable (g++ 4.6 and higher).
Defaults to off.
Tracing features:¶
- --show-scons
- Operate Scons in non-quiet mode, showing the executed commands. Defaults
to off.
- --show-progress
- Provide progress information and statistics. Defaults to off.
- --show-memory
- Provide memory information and statistics. Defaults to off.
- --show-modules
- Provide a final summary on included modules. Defaults to off.
- --verbose
- Output details of actions taken, esp. in optimizations. Can become a lot.
Defaults to off.
Windows specific output control:¶
- --windows-disable-console
- When compiling for Windows, disable the console window. Defaults to
off.
- --windows-icon=ICON_PATH,
--icon=ICON_PATH
- Add executable icon (Windows only).
Plugin control:¶
- --plugin-enable=PLUGINS_ENABLED,
--enable-plugin=PLUGINS_ENABLED
- Enabled plugins. Must be plug-in names. Use --pluginlist to query
the full list and exit. Default empty.
- --plugin-disable=PLUGINS_DISABLED,
--disable-plugin=PLUGINS_DISABLED
- Disabled plugins. Must be plug-in names. Use --pluginlist to query
the full list and exit. Default empty.
- --plugin-no-detection
- Plugins can detect if they might be used, and the you can disable the
warning via --plugin-disable=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 plug-ins to use. Defaults to off.
