This is the command pypy that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
pypy - fast, compliant alternative implementation of the Python language
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.
--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.
PyPy's default incminimark garbage collector is configurable through several environment
variables:
PYPY_GC_NURSERY
The nursery size. Defaults to 1/2 of your cache or 4M. Small values (like 1 or
1KB) are useful for debugging.
PYPY_GC_NURSERY_CLEANUP
The interval at which nursery is cleaned up. Must be smaller than the nursery size
and bigger than the biggest object we can allotate in the nursery.
PYPY_GC_INCREMENT_STEP
The size of memory marked during the marking step. Default is size of nursery
times 2. If you mark it too high your GC is not incremental at all. The minimum is
set to size that survives minor collection times 1.5 so we reclaim anything all the
time.
PYPY_GC_MAJOR_COLLECT
Major collection memory factor. Default is 1.82, which means trigger a major
collection when the memory consumed equals 1.82 times the memory really used at the
end of the previous major collection.
PYPY_GC_GROWTH
Major collection threshold's max growth rate. Default is 1.4. Useful to collect
more often than normally on sudden memory growth, e.g. when there is a temporary
peak in memory usage.
PYPY_GC_MAX
The max heap size. If coming near this limit, it will first collect more often,
then raise an RPython MemoryError, and if that is not enough, crash the program
with a fatal error. Try values like 1.6GB.
PYPY_GC_MAX_DELTA
The major collection threshold will never be set to more than PYPY_GC_MAX_DELTA the
amount really used after a collection. Defaults to 1/8th of the total RAM size
(which is constrained to be at most 2/3/4GB on 32-bit systems). Try values like
200MB.
PYPY_GC_MIN
Don't collect while the memory size is below this limit. Useful to avoid spending
all the time in the GC in very small programs. Defaults to 8 times the nursery.
PYPY_GC_DEBUG
Enable extra checks around collections that are too slow for normal use. Values
are 0 (off), 1 (on major collections) or 2 (also on minor collections).
