For most +users, it should be compatible with ``prompt_toolkit`` **2.0**, but it requires at +least **Python 3.6**. On the plus side, ``prompt_toolkit`` **3.0** is completely type +annotated and uses asyncio natively. + + +Gallery +******* + +`ptpython `_ is an interactive +Python Shell, build on top of ``prompt_toolkit``. + +.. image :: https://github.com/prompt-toolkit/python-prompt-toolkit/raw/master/docs/images/ptpython.png + +`More examples `_ + + +prompt_toolkit features +*********************** + +``prompt_toolkit`` could be a replacement for `GNU readline +`_, but it can be much +more than that. + +Some features: + +- **Pure Python**. +- Syntax highlighting of the input while typing. (For instance, with a Pygments lexer.) +- Multi-line input editing. +- Advanced code completion. +- Both Emacs and Vi key bindings. (Similar to readline.) +- Even some advanced Vi functionality, like named registers and digraphs. +- Reverse and forward incremental search. +- Works well with Unicode double width characters. (Chinese input.) +- Selecting text for copy/paste. (Both Emacs and Vi style.) +- Support for `bracketed paste `_. +- Mouse support for cursor positioning and scrolling. +- Auto suggestions. (Like `fish shell `_.) +- Multiple input buffers. +- No global state. +- Lightweight, the only dependencies are Pygments and wcwidth. +- Runs on Linux, OS X, FreeBSD, OpenBSD and Windows systems. +- And much more... + +Feel free to create tickets for bugs and feature requests, and create pull +requests if you have nice patches that you would like to share with others. + + +Installation +************ + +:: + + pip install prompt_toolkit + +For Conda, do: + +:: + + conda install -c https://conda.anaconda.org/conda-forge prompt_toolkit + + +About Windows support +********************* + +``prompt_toolkit`` is cross platform, and everything that you build on top +should run fine on both Unix and Windows systems. Windows support is best on +recent Windows 10 builds, for which the command line window supports vt100 +escape sequences. (If not supported, we fall back to using Win32 APIs for color +and cursor movements). + +It's worth noting that the implementation is a "best effort of what is +possible". Both Unix and Windows terminals have their limitations. But in +general, the Unix experience will still be a little better. + +For Windows, it's recommended to use either `cmder +`_ or `conemu `_. + +Getting started +*************** + +The most simple example of the library would look like this: + +.. code:: python + + from prompt_toolkit import prompt + + if __name__ == '__main__': + answer = prompt('Give me some input: ') + print('You said: %s' % answer) + +For more complex examples, have a look in the ``examples`` directory. All +examples are chosen to demonstrate only one thing. Also, don't be afraid to +look at the source code. The implementation of the ``prompt`` function could be +a good start. + +Philosophy +********** + +The source code of ``prompt_toolkit`` should be **readable**, **concise** and +**efficient**. We prefer short functions focusing each on one task and for which +the input and output types are clearly specified. We mostly prefer composition +over inheritance, because inheritance can result in too much functionality in +the same object. We prefer immutable objects where possible (objects don't +change after initialization). Reusability is important. We absolutely refrain +from having a changing global state, it should be possible to have multiple +independent instances of the same code in the same process. The architecture +should be layered: the lower levels operate on primitive operations and data +structures giving -- when correctly combined -- all the possible flexibility; +while at the higher level, there should be a simpler API, ready-to-use and +sufficient for most use cases. Thinking about algorithms and efficiency is +important, but avoid premature optimization. + + +`Projects using prompt_toolkit `_ +*********************************************** + +Special thanks to +***************** + +- `Pygments `_: Syntax highlighter. +- `wcwidth `_: Determine columns needed for a wide characters. + +.. |Build Status| image:: https://api.travis-ci.org/prompt-toolkit/python-prompt-toolkit.svg?branch=master + :target: https://travis-ci.org/prompt-toolkit/python-prompt-toolkit# + +.. |PyPI| image:: https://img.shields.io/pypi/v/prompt_toolkit.svg + :target: https://pypi.python.org/pypi/prompt-toolkit/ + :alt: Latest Version + +.. |AppVeyor| image:: https://ci.appveyor.com/api/projects/status/32r7s2skrgm9ubva?svg=true + :target: https://ci.appveyor.com/project/prompt-toolkit/python-prompt-toolkit/ + +.. |RTD| image:: https://readthedocs.org/projects/python-prompt-toolkit/badge/ + :target: https://python-prompt-toolkit.readthedocs.io/en/master/ + +.. |License| image:: https://img.shields.io/github/license/prompt-toolkit/python-prompt-toolkit.svg + :target: https://github.com/prompt-toolkit/python-prompt-toolkit/blob/master/LICENSE + +.. |Codecov| image:: https://codecov.io/gh/prompt-toolkit/python-prompt-toolkit/branch/master/graphs/badge.svg?style=flat + :target: https://codecov.io/gh/prompt-toolkit/python-prompt-toolkit/ + -- cgit v1.2.3
