2 | Handlers for IPythonDirective's @doctest pseudo-decorator. | |
|
3 | ||
|
4 | The Sphinx extension that provides support for embedded IPython code provides | |
|
5 | a pseudo-decorator @doctest, which treats the input/output block as a | |
|
6 | doctest, raising a RuntimeError during doc generation if the actual output | |
|
7 | (after running the input) does not match the expected output. | |
|
8 | ||
|
9 | An example usage is: | |
|
10 | ||
|
11 | .. code-block:: rst | |
|
12 | ||
|
13 | .. ipython:: | |
|
14 | ||
|
15 | In [1]: x = 1 | |
|
16 | ||
|
17 | @doctest | |
|
18 | In [2]: x + 2 | |
|
19 | Out[3]: 3 | |
|
20 | ||
|
21 | One can also provide arguments to the decorator. The first argument should be | |
|
22 | the name of a custom handler. The specification of any other arguments is | |
|
23 | determined by the handler. For example, | |
|
24 | ||
|
25 | .. code-block:: rst | |
|
26 | ||
|
27 | .. ipython:: | |
|
28 | ||
|
29 | @doctest float | |
|
30 | In [154]: 0.1 + 0.2 | |
|
31 | Out[154]: 0.3 | |
|
32 | ||
|
33 | allows the actual output ``0.30000000000000004`` to match the expected output | |
|
34 | due to a comparison with `np.allclose`. | |
|
35 | ||
|
36 | This module contains handlers for the @doctest pseudo-decorator. Handlers | |
|
37 | should have the following function signature:: | |
|
38 | ||
|
39 | handler(sphinx_shell, args, input_lines, found, submitted) | |
|
40 | ||
|
41 | where `sphinx_shell` is the embedded Sphinx shell, `args` contains the list | |
|
42 | of arguments that follow: '@doctest handler_name', `input_lines` contains | |
|
43 | a list of the lines relevant to the current doctest, `found` is a string | |
|
44 | containing the output from the IPython shell, and `submitted` is a string | |
|
45 | containing the expected output from the IPython shell. | |
|
46 | ||
|
47 | Handlers must be registered in the `doctests` dict at the end of this module. | |

|
2 | """ | |
|
3 | Sphinx directive to support embedded IPython code. | |
|
3 | 4 | |
|
4 | 5 | This directive allows pasting of entire interactive IPython sessions, prompts |
|
5 | 6 | and all, and their code will actually get re-executed at doc build time, with |
|
6 | 7 | all prompts renumbered sequentially. It also allows you to input code as a pure |
|
7 | 8 | python input by giving the argument python to the directive. The output looks |
|
8 | 9 | like an interactive ipython section. |
|
9 | 10 | |
|
10 | 11 | To enable this directive, simply list it in your Sphinx ``conf.py`` file |
|
11 | 12 | (making sure the directory where you placed it is visible to sphinx, as is |
|
12 | needed for all Sphinx directives). | |
|
13 | needed for all Sphinx directives). For example, to enable syntax highlighting | |
|
14 | and the IPython directive:: | |
|
15 | ||
|
16 | extensions = ['IPython.sphinxext.ipython_console_highlighting', | |
|
17 | 'IPython.sphinxext.ipython_directive'] | |
|
13 | 18 | |
|
14 | By default this directive assumes that your prompts are unchanged IPython ones, | |
|
15 | but this can be customized. The configurable options that can be placed in | |
|
16 | conf.py are | |
|
19 | The IPython directive outputs code-blocks with the language 'ipython'. So | |
|
20 | if you do not have the syntax highlighting extension enabled as well, then | |
|
21 | all rendered code-blocks will be uncolored. By default this directive assumes | |
|
22 | that your prompts are unchanged IPython ones, but this can be customized. | |
|
23 | The configurable options that can be placed in conf.py are: | |
|
17 | 24 | |
|
18 | 25 | ipython_savefig_dir: |
|
19 | 26 | The directory in which to save the figures. This is relative to the |
|
20 | 27 | Sphinx source directory. The default is `html_static_path`. |
|
21 | 28 | ipython_rgxin: |
|
22 | 29 | The compiled regular expression to denote the start of IPython input |
|
23 | 30 | lines. The default is re.compile('In \[(\d+)\]:\s?(.*)\s*'). You |
|
24 | 31 | shouldn't need to change this. |
|
25 | 32 | ipython_rgxout: |
|
26 | 33 | The compiled regular expression to denote the start of IPython output |
|
27 | 34 | lines. The default is re.compile('Out\[(\d+)\]:\s?(.*)\s*'). You |
|
28 | 35 | shouldn't need to change this. |
|
29 | 36 | ipython_promptin: |
|
30 | 37 | The string to represent the IPython input prompt in the generated ReST. |
|
31 | 38 | The default is 'In [%d]:'. This expects that the line numbers are used |
|
32 | 39 | in the prompt. |
|
33 | 40 | ipython_promptout: |
|
34 | 41 | The string to represent the IPython prompt in the generated ReST. The |
|
35 | 42 | default is 'Out [%d]:'. This expects that the line numbers are used |
|
36 | 43 | in the prompt. |
|
44 | ipython_mplbackend: | |
|
45 | The string which specifies if the embedded Sphinx shell should import | |
|
46 | Matplotlib and set the backend. The value specifies a backend that is | |
|
47 | passed to `matplotlib.use()` before any lines in `ipython_execlines` are | |
|
48 | executed. If not specified in conf.py, then the default value of 'agg' is | |
|
49 | used. To use the IPython directive without matplotlib as a dependency, set | |
|
50 | the value to `None`. It may end up that matplotlib is still imported | |
|
51 | if the user specifies so in `ipython_execlines` or makes use of the | |
|
52 | @savefig pseudo decorator. | |
|
53 | ipython_execlines: | |
|
54 | A list of strings to be exec'd in the embedded Sphinx shell. Typical | |
|
55 | usage is to make certain packages always available. Set this to an empty | |
|
56 | list if you wish to have no imports always available. If specified in | |
|
57 | conf.py as `None`, then it has the effect of making no imports available. | |
|
58 | If omitted from conf.py altogether, then the default value of | |
|
59 | ['import numpy as np', 'import matplotlib.pyplot as plt'] is used. | |
|
60 | ipython_holdcount | |
|
61 | When the @suppress pseudo-decorator is used, the execution count can be | |
|
62 | incremented or not. The default behavior is to hold the execution count, | |
|
63 | corresponding to a value of `True`. Set this to `False` to increment | |
|
64 | the execution count after each suppressed command. | |
|
65 | ||
|
66 | As an example, to use the IPython directive when `matplotlib` is not available, | |
|
67 | one sets the backend to `None`:: | |
|
68 | ||
|
69 | ipython_mplbackend = None | |
|
70 | ||
|
71 | An example usage of the directive is: | |
|
72 | ||
|
73 | .. code-block:: rst | |
|
74 | ||
|
75 | .. ipython:: | |
|
76 | ||

|
78 | ||
|
79 | In [2]: y = x**2 | |
