============
Introduction
============

This library is mainly for CLI programs that carefully produce output for
Terminals, or make pretend to be an emulator.

**Problem Statement**: The printable length of *most* strings are equal to the
number of cells they occupy on the screen ``1 character : 1 cell``.  However,
there are categories of characters that *occupy 2 cells* (full-wide), and
others that *occupy 0* cells (zero-width).

**Solution**: POSIX.1-2001 and POSIX.1-2008 conforming systems provide
`wcwidth(3)`_ and `wcswidth(3)`_ C functions of which this python module's
functions precisely copy.  *These functions return the number of cells a
unicode string is expected to occupy.*

Installation
------------

The stable version of this package is maintained on pypi, install using pip::

    pip install wcwidth

Example
-------

**Problem**: given the following phrase (Japanese),

   >>>  text = u'コンニチハ'

Python **incorrectly** uses the *string length* of 5 codepoints rather than the
*printible length* of 10 cells, so that when using the `rjust` function, the
output length is wrong::

    >>> print(len('コンニチハ'))
    5

    >>> print('コンニチハ'.rjust(20, '_'))
    _______________コンニチハ

By defining our own "rjust" function that uses wcwidth, we can correct this::

   >>> def wc_rjust(text, length, padding=' '):
   ...    from wcwidth import wcswidth
   ...    return padding * max(0, (length - wcswidth(text))) + text
   ...

Our **Solution** uses wcswidth to determine the string length correctly::

   >>> from wcwidth import wcswidth
   >>> print(wcswidth('コンニチハ'))
   10

   >>> print(wc_rjust('コンニチハ', 20, '_'))
   __________コンニチハ


Choosing a Version
------------------

Export an environment variable, ``UNICODE_VERSION``. This should be done by
*terminal emulators* or those developers experimenting with authoring one of
their own, from shell::

   $ export UNICODE_VERSION=13.0

If unspecified, the latest version is used. If your Terminal Emulator does not
export this variable, you can use the `jquast/ucs-detect`_ utility to
automatically detect and export it to your shell.

wcwidth, wcswidth
-----------------
Use function ``wcwidth()`` to determine the length of a *single unicode
character*, and ``wcswidth()`` to determine the length of many, a *string
of unicode characters*.

Briefly, return values of function ``wcwidth()`` are:

``-1``
  Indeterminate (not printable).

``0``
  Does not advance the cursor, such as NULL or Combining.

``2``
  Characters of category East Asian Wide (W) or East Asian
  Full-width (F) which are displayed using two terminal cells.

``1``
  All others.

Function ``wcswidth()`` simply returns the sum of all values for each character
along a string, or ``-1`` when it occurs anywhere along a string.

==========
Developing
==========

Install wcwidth in editable mode::

   pip install -e .

Execute unit tests using tox_::

   tox -e py27,py35,py36,py37,py38,py39,py310,py311,py312

Updating Unicode Version
------------------------

Regenerate python code tables from latest Unicode Specification data files::

   tox -e update

The script is located at ``bin/update-tables.py``, requires Python 3.9 or
later. It is recommended but not necessary to run this script with the newest
Python, because the newest Python has the latest ``unicodedata`` for generating
comments.

Building Documentation
----------------------

This project is using `sphinx`_ 4.5 to build documentation::

   tox -e sphinx

The output will be in ``docs/_build/html/``.

Updating Requirements
---------------------

This project is using `pip-tools`_ to manage requirements.

To upgrade requirements for updating unicode version, run::

   tox -e update_requirements_update

To upgrade requirements for testing, run::

   tox -e update_requirements37,update_requirements39

To upgrade requirements for building documentation, run::

   tox -e update_requirements_docs

Utilities
---------

Supplementary tools for browsing and testing terminals for wide unicode
characters are found in the `bin/`_ of this project's source code.  Just ensure
to first ``pip install -r requirements-develop.txt`` from this projects main
folder. For example, an interactive browser for testing::

  python ./bin/wcwidth-browser.py
