"""Sphinx directive to support embedded IPython code.
|
|
|
|
|
|
This directive allows pasting of entire interactive IPython sessions, prompts
|
|
|
and all, and their code will actually get re-executed at doc build time, with
|
|
|
all prompts renumbered sequentially. It also allows you to input code as a pure
|
|
|
python input by giving the argument python to the directive. The output looks
|
|
|
like an interactive ipython section.
|
|
|
|
|
|
To enable this directive, simply list it in your Sphinx ``conf.py`` file
|
|
|
(making sure the directory where you placed it is visible to sphinx, as is
|
|
|
needed for all Sphinx directives). For example, to enable syntax highlighting
|
|
|
and the IPython directive::
|
|
|
|
|
|
extensions = ['IPython.sphinxext.ipython_console_highlighting',
|
|
|
'IPython.sphinxext.ipython_directive']
|
|
|
|
|
|
By default this directive assumes that your prompts are unchanged IPython ones,
|
|
|
but this can be customized. The configurable options that can be placed in
|
|
|
conf.py are:
|
|
|
|
|
|
ipython_savefig_dir:
|
|
|
The directory in which to save the figures. This is relative to the
|
|
|
Sphinx source directory. The default is `html_static_path`.
|
|
|
ipython_rgxin:
|
|
|
The compiled regular expression to denote the start of IPython input
|
|
|
lines. The default is re.compile('In \[(\d+)\]:\s?(.*)\s*'). You
|
|
|
shouldn't need to change this.
|
|
|
ipython_rgxout:
|
|
|
The compiled regular expression to denote the start of IPython output
|
|
|
lines. The default is re.compile('Out\[(\d+)\]:\s?(.*)\s*'). You
|
|
|
shouldn't need to change this.
|
|
|
ipython_promptin:
|
|
|
The string to represent the IPython input prompt in the generated ReST.
|
|
|
The default is 'In [%d]:'. This expects that the line numbers are used
|
|
|
in the prompt.
|
|
|
ipython_promptout:
|
|
|
The string to represent the IPython prompt in the generated ReST. The
|
|
|
default is 'Out [%d]:'. This expects that the line numbers are used
|
|
|
in the prompt.
|
|
|
ipython_mplbackend:
|
|
|
The string which specifies if the embedded Sphinx shell should import
|
|
|
Matplotlib and set the backend for each code-block. If `None`, or equal
|
|
|
to '' or 'None', then `matplotlib` will not be automatically imported. If
|
|
|
not `None`, then the value should specify a backend that is passed to
|
|
|
`matplotlib.use()`. The default value is 'agg'.
|
|
|
ipython_execlines:
|
|
|
A list of strings to be exec'd for each embedded Sphinx shell. Typical
|
|
|
usage is to make certain packages always available. If None, then
|
|
|
`['import numpy as np', 'from pylab import *']` is used. Set this to an
|
|
|
empty list if you wish to have no imports always available.
|
|
|
|
|
|
As an example, to use the IPython directive when `matplotlib` is not available,
|
|
|
one sets the backend to `None`::
|
|
|
|
|
|
ipython_mplbacked = None
|
|
|
|
|
|
|
|
|
ToDo
|
|
|
----
|
|
|
|
|
|
- Turn the ad-hoc test() function into a real test suite.
|
|
|
- Break up ipython-specific functionality from matplotlib stuff into better
|
|
|
separated code.
