2 | 2 | """Sphinx directive to support embedded IPython code. |
|
3 | 3 | |
|
4 | 4 | This directive allows pasting of entire interactive IPython sessions, prompts |
|
5 | 5 | and all, and their code will actually get re-executed at doc build time, with |
|
6 | 6 | all prompts renumbered sequentially. It also allows you to input code as a pure |
|
7 | 7 | python input by giving the argument python to the directive. The output looks |
|
8 | 8 | like an interactive ipython section. |
|
9 | 9 | |
|
10 | 10 | To enable this directive, simply list it in your Sphinx ``conf.py`` file |
|
11 | 11 | (making sure the directory where you placed it is visible to sphinx, as is |
|
12 | 12 | needed for all Sphinx directives). For example, to enable syntax highlighting |
|
13 | 13 | and the IPython directive:: |
|
14 | 14 | |
|
15 | 15 | extensions = ['IPython.sphinxext.ipython_console_highlighting', |
|
16 | 16 | 'IPython.sphinxext.ipython_directive'] |
|
17 | 17 | |
|
18 | 18 | The IPython directive outputs code-blocks with the language 'ipython'. So |
|
19 | 19 | if you do not have the syntax highlighting extension enabled as well, then |
|
20 | 20 | all rendered code-blocks will be uncolored. By default this directive assumes |
|
21 | 21 | that your prompts are unchanged IPython ones, but this can be customized. |
|
22 | 22 | The configurable options that can be placed in conf.py are: |
|
23 | 23 | |
|
24 | 24 | ipython_savefig_dir: |
|
25 | 25 | The directory in which to save the figures. This is relative to the |
|
26 | 26 | Sphinx source directory. The default is `html_static_path`. |
|
27 | 27 | ipython_rgxin: |
|
28 | 28 | The compiled regular expression to denote the start of IPython input |
|
29 | 29 | lines. The default is re.compile('In \[(\d+)\]:\s?(.*)\s*'). You |
|
30 | 30 | shouldn't need to change this. |
|
31 | 31 | ipython_rgxout: |
|
32 | 32 | The compiled regular expression to denote the start of IPython output |
|
33 | 33 | lines. The default is re.compile('Out\[(\d+)\]:\s?(.*)\s*'). You |
|
34 | 34 | shouldn't need to change this. |
|
35 | 35 | ipython_promptin: |
|
36 | 36 | The string to represent the IPython input prompt in the generated ReST. |
|
37 | 37 | The default is 'In [%d]:'. This expects that the line numbers are used |
|
38 | 38 | in the prompt. |
|
39 | 39 | ipython_promptout: |
|
40 | 40 | The string to represent the IPython prompt in the generated ReST. The |
|
41 | 41 | default is 'Out [%d]:'. This expects that the line numbers are used |
|
42 | 42 | in the prompt. |
|
43 | 43 | ipython_mplbackend: |
|
44 | 44 | The string which specifies if the embedded Sphinx shell should import |
|
45 | 45 | Matplotlib and set the backend. The value specifies a backend that is |
|
46 | 46 | passed to `matplotlib.use()` before any lines in `ipython_execlines` are |
|
47 | 47 | executed. If specified in conf.py as `None` or not specified in conf.py at |
|
48 | 48 | all, then no call to `matplotlib.use()` is made. Then, matplotlib is loaded |
|
49 | 49 | only if specified in `ipython_execlines` or if the @savefig pseudo |
|
50 | 50 | decorator is used. In the latter case, matplotlib is imported and its |
|
51 | 51 | default backend is used. |
|
52 | 52 | ipython_execlines: |
|
53 | 53 | A list of strings to be exec'd for the embedded Sphinx shell. Typical |
|
54 | 54 | usage is to make certain packages always available. Set this to an empty |
|
55 | 55 | list if you wish to have no imports always available. If specified in |
|
56 | 56 | conf.py as `None` or not specified in conf.py at all, then the default |
|
57 | 57 | value of ['import numpy as np', 'from pylab import *'] is used. |
|
58 | 58 | |
|
59 | 59 | As an example, to use the IPython directive when `matplotlib` is not available, |
|
60 | 60 | one sets the backend to `None`:: |
|
61 | 61 | |
|
62 | 62 | ipython_mplbacked = None |
|
63 | 63 | |
|
64 | 64 | An example usage of the directive is: |
|
65 | 65 | |
|
66 | 66 | .. code-block:: rst |
|
67 | 67 | |
|
68 | 68 | .. ipython:: |
|
69 | 69 | |
|
70 | 70 | In [1]: x = 1 |
|
71 | 71 | |
|
72 | 72 | In [2]: y = x**2 |
|
73 | 73 | |
|
74 | 74 | In [3]: print(y) |
|
75 | 75 | |
|
76 | 76 | See http://matplotlib.org/sampledoc/ipython_directive.html for more additional |
|
77 | 77 | documentation. |

|
79 | 79 | ToDo |

81 | 81 | |
|
82 | 82 | - Turn the ad-hoc test() function into a real test suite. |
|
83 | 83 | - Break up ipython-specific functionality from matplotlib stuff into better |
|
84 | 84 | separated code. |
