python-creole is an open-source (GPL) markup converter in pure Python for: creole2html, html2creole, html2ReSt, html2textile

= about python-creole =

python-creole is a OpenSource (GPL) Python lib for converting markups.
python-creole is pure python. No external libs needed.

Compatible Python Versions (see [[https://github.com/jedie/python-creole/blob/master/tox.ini|tox.ini]] or [[https://github.com/jedie/python-creole/blob/master/.travis.yml|.travis.yml]]):
 * 3.8, 3.7, 3.6
 * PyPy3


Existing converters:

* creole -> html
* html -> creole markup
* reSt -> html (for clean html code)
* html -> reStructuredText markup (only a subset of reSt supported)
* html -> textile markup (not completed yet)

The creole2html part based on the creole markup parser and emitter from the MoinMoin project by Radomir Dopieralski and Thomas Waldmann.

= install =

Python packages available on: [[http://pypi.python.org/pypi/python-creole/]]

{{{
~$ pip install python-creole
}}}

To setup a virtualenv via Poetry, see {{{unittests}}} section below.

== dependencies ==

For the most parts ({{{creole2html}}} and {{{html2creole}}}) no external libraries are needed.

For all functionality (and running the unittests) these modules are needed:

* [[http://pypi.python.org/pypi/docutils/|docutils]] (for the ReStructuredText stuff)
* [[http://pypi.python.org/pypi/textile/|textile]] (for html2textile tests)


= example =

== creole2html ==
Convert creole markup to html code:
{{{
>>> from creole import creole2html
>>> creole2html("This is **creole //markup//**")
u'<p>This is <strong>creole <i>markup</i></strong></p>\n'
}}}


== html2creole ==
Convert html code back into creole markup:
{{{
>>> from creole import html2creole
>>> html2creole(u'<p>This is <strong>creole <i>markup</i></strong></p>\n')
u'This is **creole //markup//**'
}}}


== rest2html ==
Convert ReStructuredText into clean html code (needs [[http://pypi.python.org/pypi/docutils/|docutils]]):
{{{
>>> from creole.rest2html.clean_writer import rest2html
>>> rest2html(u"A ReSt link to `PyLucid CMS <http://www.pylucid.org>`_ :)")
u'<p>A ReSt link to <a href="http://www.pylucid.org">PyLucid CMS</a> :)</p>\\n'
}}}
(more information: [[https://github.com/jedie/python-creole/wiki/rest2html|rest2html wiki page]])


== html2rest ==
Convert html code into ReStructuredText markup:
{{{
>>> from creole import html2rest
>>> html2rest(u'<p>This is <strong>ReStructuredText</strong> <em>markup</em>!</p>')
u'This is **ReStructuredText** *markup*!'
}}}


== html2textile ==
Convert html code into textile markup
{{{
>>> from creole import html2textile
>>> html2textile(u'<p>This is <strong>textile <i>markup</i></strong>!</p>')
u'This is *textile __markup__*!'
}}}

See also: [[http://github.com/jedie/python-creole/blob/master/demo.py]]

= Image size additional =

You can pass image width/height in image tags, e.g.:
{{{
>>> from creole import creole2html
>>> creole_markup="""{{foobar.jpg|image title|90x160}}"""
>>> creole2html(creole_markup)
'<p><img src="foobar.jpg" title="image title" alt="image title" width="90" height="160" /></p>'
}}}

The third part ({{{90x160}}}) is not in creole standard, you can force a //strict// mode, e.g.:
{{{
>>> creole2html(creole_markup, strict=True)
'<p><img src="foobar.jpg" title="image title|90x160" alt="image title|90x160" /></p>'
}}}

= Source code highlighting support =

You can find a example macro which highlight source code thanks to the pygments
library. It is located here: [[https://github.com/jedie/python-creole/blob/master/creole/shared/example_macros.py|/creole/shared/example_macros.py]].
Here is how to use it:

{{{
>>> from creole import creole2html
>>> from creole.shared.example_macros import code
>>> creole_markup="""<<code ext=".py">>#some code\nprint('coucou')\n<</code>>"""
>>> creole2html(creole_markup, macros={'code': code})
}}}

= commandline interface =

If you have python-creole installed, you will get these simple CLI scripts:
* creole2html
* html2creole
* html2rest
* html2textile

Here the {{{--help}}} output from {{{html2creole}}}:
{{{
$ html2creole --help
usage: html2creole [-h] [-v] [--encoding ENCODING] sourcefile destination

python-creole is an open-source (GPL) markup converter in pure Python for:
creole2html, html2creole, html2ReSt, html2textile

positional arguments:
  sourcefile           source file to convert
  destination          Output filename

optional arguments:
  -h, --help           show this help message and exit
  -v, --version        show program's version number and exit
  --encoding ENCODING  Codec for read/write file (default encoding: utf-8)
}}}

Example to convert a html file into a creole file:
{{{
$ html2creole foobar.html foobar.creole
}}}

= documentation =

We store documentation/examples into the project wiki:

* [[https://github.com/jedie/python-creole/wiki]]

== unittests ==

{{{
# clone repository (or use your fork):
~$ git clone https://github.com/jedie/python-creole.git
~$ cd python-creole

# install or update poetry:
~/python-crole$ make install-poetry

# install python-creole via poetry:
~/python-crole$ make install

# Run pytest:
~/python-crole$ make pytest

}}}


== Use creole in README ==

With python-creole you can convert a README on-the-fly from creole into ReStructuredText in setup.py
How to do this, read: https://github.com/jedie/python-creole/wiki/Use-In-Setup

Note: In this case you must install **docutils**! See above.
