======
pypy
======
.. note: this is turned into a regular man page "pypy.1" by
doing "make man" in pypy/doc/
SYNOPSIS
========
``pypy`` [*options*]
[``-c`` *cmd*\ \|\ ``-m`` *mod*\ \|\ *file.py*\ \|\ ``-``\ ]
[*arg*\ ...]
OPTIONS
=======
-i
Inspect interactively after running script.
-O
Skip assert statements.
-OO
Remove docstrings when importing modules in addition to ``-O``.
-c CMD
Program passed in as ``CMD`` (terminates option list).
-S
Do not ``import site`` on initialization.
-s
Don't add the user site directory to `sys.path`.
-u
Unbuffered binary ``stdout`` and ``stderr``.
-h, --help
Show a help message and exit.
-m MOD
Library module to be run as a script (terminates option list).
-W ARG
Warning control (*arg* is *action*:*message*:*category*:*module*:*lineno*).
-E
Ignore environment variables (such as ``PYTHONPATH``).
-B
Disable writing bytecode (``.pyc``) files.
-X track-resources
Produce a ``ResourceWarning`` whenever a file or socket is closed by the
garbage collector.
--version
Print the PyPy version.
--info
Print translation information about this PyPy executable.
--jit ARG
Low level JIT parameters. Mostly internal. Run ``--jit help``
for more information.
ENVIRONMENT
===========
``PYTHONPATH``
Add directories to pypy's module search path.
The format is the same as shell's ``PATH``.
``PYTHONSTARTUP``
A script referenced by this variable will be executed before the
first prompt is displayed, in interactive mode.
``PYTHONDONTWRITEBYTECODE``
If set to a non-empty value, equivalent to the ``-B`` option.
Disable writing ``.pyc`` files.
``PYTHONINSPECT``
If set to a non-empty value, equivalent to the ``-i`` option.
Inspect interactively after running the specified script.
``PYTHONIOENCODING``
If this is set, it overrides the encoding used for
*stdin*/*stdout*/*stderr*.
The syntax is *encodingname*:*errorhandler*
The *errorhandler* part is optional and has the same meaning as in
`str.encode`.
``PYTHONNOUSERSITE``
If set to a non-empty value, equivalent to the ``-s`` option.
Don't add the user site directory to `sys.path`.
``PYTHONWARNINGS``
If set, equivalent to the ``-W`` option (warning control).
The value should be a comma-separated list of ``-W`` parameters.
``PYPYLOG``
If set to a non-empty value, enable logging, the format is:
*fname* or *+fname*
logging for profiling: includes all
``debug_start``/``debug_stop`` but not any nested
``debug_print``.
*fname* can be ``-`` to log to *stderr*.
The *+fname* form can be used if there is a *:* in fname
``:``\ *fname*
Full logging, including ``debug_print``.
*prefix*\ ``:``\ *fname*
Conditional logging.
Multiple prefixes can be specified, comma-separated.
Only sections whose name match the prefix will be logged.
``PYPYLOG=jit-log-opt,jit-backend:logfile`` will
generate a log suitable for *jitviewer*, a tool for debugging
performance issues under PyPy.
``PYPY_IRC_TOPIC``
If set to a non-empty value, print a random #pypy IRC
topic at startup of interactive mode.
