Metadata-Version: 2.1
Name: ptpython
Version: 3.0.20
Summary: Python REPL build on top of prompt_toolkit
Home-page: https://github.com/prompt-toolkit/ptpython
Author: Jonathan Slenders
License: UNKNOWN
Description: ptpython
========
|Build Status| |PyPI| |License|
*A better Python REPL*
::
pip install ptpython
.. image :: https://github.com/jonathanslenders/ptpython/raw/master/docs/images/example1.png
Ptpython is an advanced Python REPL. It should work on all
Python versions from 2.6 up to 3.9 and work cross platform (Linux,
BSD, OS X and Windows).
Note: this version of ptpython requires at least Python 3.6. Install ptpython
2.0.5 for older Python versions.
Installation
************
Install it using pip:
::
pip install ptpython
Start it by typing ``ptpython``.
Features
********
- Syntax highlighting.
- Multiline editing (the up arrow works).
- Autocompletion.
- Mouse support. [1]
- Support for color schemes.
- Support for `bracketed paste <https://cirw.in/blog/bracketed-paste>`_ [2].
- Both Vi and Emacs key bindings.
- Support for double width (Chinese) characters.
- ... and many other things.
[1] Disabled by default. (Enable in the menu.)
[2] If the terminal supports it (most terminals do), this allows pasting
without going into paste mode. It will keep the indentation.
__pt_repr__: A nicer repr with colors
*************************************
When classes implement a ``__pt_repr__`` method, this will be used instead of
``__repr__`` for printing. Any `prompt_toolkit "formatted text"
<https://python-prompt-toolkit.readthedocs.io/en/master/pages/printing_text.html>`_
can be returned from here. In order to avoid writing a ``__repr__`` as well,
the ``ptpython.utils.ptrepr_to_repr`` decorator can be applied. For instance:
.. code:: python
from ptpython.utils import ptrepr_to_repr
from prompt_toolkit.formatted_text import HTML
@ptrepr_to_repr
class MyClass:
def __pt_repr__(self):
return HTML('<yellow>Hello world!</yellow>')

Autocompletion:

Embedding the REPL
******************
Embedding the REPL in any Python application is easy:
.. code:: python
from ptpython.repl import embed
embed(globals(), locals())
You can make ptpython your default Python REPL by creating a `PYTHONSTARTUP file
<https://docs.python.org/3/tutorial/appendix.html#the-interactive-startup-file>`_ containing code
like this:
.. code:: python
import sys
try:
from ptpython.repl import embed
except ImportError:
print("ptpython is not available: falling back to standard prompt")
else:
sys.exit(embed(globals(), locals()))
Multiline editing
*****************
Multi-line editing mode will automatically turn on when you press enter after a
colon.
To execute the input in multi-line mode, you can either press ``Alt+Enter``, or
``Esc`` followed by ``Enter``. (If you want the first to work in the OS X
terminal, you have to check the "Use option as meta key" checkbox in your
terminal settings. For iTerm2, you have to check "Left option acts as +Esc" in
the options.)
.. image :: https://github.com/jonathanslenders/ptpython/raw/master/docs/images/multiline.png
Syntax validation
*****************
Before execution, ``ptpython`` will see whether the input is syntactically
correct Python code. If not, it will show a warning, and move the cursor to the
error.
.. image :: https://github.com/jonathanslenders/ptpython/raw/master/docs/images/validation.png
Additional features
*******************
Running system commands: Press ``Meta-!`` in Emacs mode or just ``!`` in Vi
navigation mode to see the "Shell command" prompt. There you can enter system
commands without leaving the REPL.
Selecting text: Press ``Control+Space`` in Emacs mode or ``V`` (major V) in Vi
navigation mode.
Configuration
*************
It is possible to create a ``config.py`` file to customize configuration.
ptpython will look in an appropriate platform-specific directory via `appdirs
<https://pypi.org/project/appdirs/>`. See the ``appdirs`` documentation for the
precise location for your platform. A ``PTPYTHON_CONFIG_HOME`` environment
variable, if set, can also be used to explicitly override where configuration
is looked for.
Have a look at this example to see what is possible:
`config.py <https://github.com/jonathanslenders/ptpython/blob/master/examples/ptpython_config/config.py>`_
IPython support
***************
Run ``ptipython`` (prompt_toolkit - IPython), to get a nice interactive shell
with all the power that IPython has to offer, like magic functions and shell
integration. Make sure that IPython has been installed. (``pip install
ipython``)
.. image :: https://github.com/jonathanslenders/ptpython/raw/master/docs/images/ipython.png
This is also available for embedding:
.. code:: python
from ptpython.ipython.repl import embed
embed(globals(), locals())
Django support
**************
`django-extensions <https://github.com/django-extensions/django-extensions>`_
has a ``shell_plus`` management command. When ``ptpython`` has been installed,
it will by default use ``ptpython`` or ``ptipython``.
PDB
***
There is an experimental PDB replacement: `ptpdb
<https://github.com/jonathanslenders/ptpdb>`_.
Windows support
***************
``prompt_toolkit`` and ``ptpython`` works better on Linux and OS X than on
Windows. Some things might not work, but it is usable:

FAQ
***
**Q**: The ``Ctrl-S`` forward search doesn't work and freezes my terminal.
**A**: Try to run ``stty -ixon`` in your terminal to disable flow control.
**Q**: The ``Meta``-key doesn't work.
**A**: For some terminals you have to enable the Alt-key to act as meta key, but you
can also type ``Escape`` before any key instead.
Alternatives
************
- `BPython <http://bpython-interpreter.org/downloads.html>`_
- `IPython <https://ipython.org/>`_
If you find another alternative, you can create an issue and we'll list it
here. If you find a nice feature somewhere that is missing in ``ptpython``,
also create a GitHub issue and maybe we'll implement it.
