The Very High Level Layer
*************************
The functions in this chapter will let you execute Python source code given in a
file or a buffer, but they will not let you interact in a more detailed way with
the interpreter.
Several of these functions accept a start symbol from the grammar as a
parameter. The available start symbols are :const:`Py_eval_input`,
:const:`Py_file_input`, and :const:`Py_single_input`. These are described
following the functions which accept them as parameters.
Note also that several of these functions take :c:type:`FILE\*` parameters. One
particular issue which needs to be handled carefully is that the :c:type:`FILE`
2007-08-15 11:28:22 -03:00
structure for different C libraries can be different and incompatible. Under
Windows (at least), it is possible for dynamically linked extensions to actually
use different libraries, so care should be taken that :c:type:`FILE\*` parameters
2007-08-15 11:28:22 -03:00
are only passed to these functions if it is certain that they were created by
the same library that the Python runtime is using.
.. c:function:: int Py_Main(int argc, wchar_t **argv)
The main program for the standard interpreter. This is made available for
programs which embed Python. The *argc* and *argv* parameters should be
prepared exactly as those which are passed to a C program's :c:func:`main`
function (converted to wchar_t according to the user's locale). It is
important to note that the argument list may be modified (but the contents of
the strings pointed to by the argument list are not). The return value will
be ``0`` if the interpreter exits normally (i.e., without an exception),
``1`` if the interpreter exits due to an exception, or ``2`` if the parameter
list does not represent a valid Python command line.

This is a simplified interface to :c:func:`PyRun_AnyFileExFlags` below, leaving

the *closeit* argument set to ``0``.

If *fp* refers to a file associated with an interactive device (console or
terminal input or Unix pseudo-terminal), return the value of
:c:func:`PyRun_InteractiveLoop`, otherwise return the result of
:c:func:`PyRun_SimpleFile`. *filename* is decoded from the filesystem
encoding (:func:`sys.getfilesystemencoding`). If *filename* is *NULL*, this

.. c:function:: int PyRun_SimpleStringFlags(const char *command, PyCompilerFlags *flags)
2007-08-15 11:28:22 -03:00
Executes the Python source code from *command* in the :mod:`__main__` module
according to the *flags* argument. If :mod:`__main__` does not already exist, it
is created. Returns ``0`` on success or ``-1`` if an exception was raised. If
there was an error, there is no way to get the exception information. For the

2007-08-15 11:28:22 -03:00
Similar to :c:func:`PyRun_SimpleStringFlags`, but the Python source code is read
from *fp* instead of an in-memory string. *filename* should be the name of
the file, it is decoded from the filesystem encoding
(:func:`sys.getfilesystemencoding`). If *closeit* is true, the file is
closed before PyRun_SimpleFileExFlags returns.

.. c:function:: int PyRun_InteractiveOneFlags(FILE *fp, const char *filename, PyCompilerFlags *flags)
2007-08-15 11:28:22 -03:00
Read and execute a single statement from a file associated with an
interactive device according to the *flags* argument. The user will be
prompted using ``sys.ps1`` and ``sys.ps2``. *filename* is decoded from the
filesystem encoding (:func:`sys.getfilesystemencoding`).
Returns ``0`` when the input was
executed successfully, ``-1`` if there was an exception, or an error code
from the :file:`errcode.h` include file distributed as part of Python if
there was a parse error. (Note that :file:`errcode.h` is not included by
:file:`Python.h`, so must be included specifically if needed.)

.. c:function:: int PyRun_InteractiveLoopFlags(FILE *fp, const char *filename, PyCompilerFlags *flags)
2007-08-15 11:28:22 -03:00
Read and execute statements from a file associated with an interactive device
until EOF is reached. The user will be prompted using ``sys.ps1`` and
``sys.ps2``. *filename* is decoded from the filesystem encoding
(:func:`sys.getfilesystemencoding`). Returns ``0`` at EOF.

.. c:function:: struct _node* PyParser_SimpleParseStringFlagsFilename( const char *str, const char *filename, int start, int flags)
2007-08-15 11:28:22 -03:00
Parse Python source code from *str* using the start token *start* according to
the *flags* argument. The result can be used to create a code object which can
be evaluated efficiently. This is useful if a code fragment must be evaluated
many times. *filename* is decoded from the filesystem encoding
(:func:`sys.getfilesystemencoding`).

.. c:function:: PyObject* PyRun_StringFlags(const char *str, int start, PyObject *globals, PyObject *locals, PyCompilerFlags *flags)
2007-08-15 11:28:22 -03:00
Execute Python source code from *str* in the context specified by the
dictionaries *globals* and *locals* with the compiler flags specified by
*flags*. The parameter *start* specifies the start token that should be used to
parse the source code.
Returns the result of executing the code as a Python object, or *NULL* if an
exception was raised.

2007-08-15 11:28:22 -03:00
Parse and compile the Python source code in *str*, returning the resulting code
object. The start token is given by *start*; this can be used to constrain the
code which can be compiled and should be :const:`Py_eval_input`,
:const:`Py_file_input`, or :const:`Py_single_input`. The filename specified by
*filename* is used to construct the code object and may appear in tracebacks or
:exc:`SyntaxError` exception messages, it is decoded from the filesystem
encoding (:func:`sys.getfilesystemencoding`). This returns *NULL* if the
code cannot be parsed or compiled.
2007-08-15 11:28:22 -03:00
The integer *optimize* specifies the optimization level of the compiler; a
value of ``-1`` selects the optimization level of the interpreter as given by
:option:`-O` options. Explicit levels are ``0`` (no optimization;
``__debug__`` is true), ``1`` (asserts are removed, ``__debug__`` is false)
or ``2`` (docstrings are removed too).

This is the main, unvarnished function of Python interpretation. It is
literally 2000 lines long. The code object associated with the execution
frame *f* is executed, interpreting bytecode and executing calls as needed.
The additional *throwflag* parameter can mostly be ignored - if true, then
it causes an exception to immediately be thrown; this is used for the
:meth:`throw` methods of generator objects.

This is the structure used to hold compiler flags. In cases where code is only

executed, it is passed as ``PyCompilerFlags *flags``. In this case, ``from
__future__ import`` can modify *flags*.
Whenever ``PyCompilerFlags *flags`` is *NULL*, :attr:`cf_flags` is treated as
equal to ``0``, and any modification due to ``from __future__ import`` is
discarded. ::
