1 | 1 | ============================= |
|
2 | 2 | IPython module reorganization |
|
3 | 3 | ============================= |
|
4 | 4 | |
|
5 | 5 | Currently, IPython has many top-level modules that serve many different purposes. |
|
6 | 6 | The lack of organization make it very difficult for developers to work on IPython |
|
7 | 7 | and understand its design. This document contains notes about how we will reorganize |
|
8 | 8 | the modules into sub-packages. |
|
9 | 9 | |
|
10 | 10 | .. warning:: |
|
11 | 11 | |
|
12 | 12 | This effort will possibly break third party packages that use IPython as |
|
13 | 13 | a library or hack on the IPython internals. |
|
14 | 14 | |
|
15 | 15 | .. warning:: |
|
16 | 16 | |
|
17 | 17 | This effort will result in the removal from IPython of certain modules |
|
18 | 18 | that are not used anymore, don't currently work, are unmaintained, etc. |
|

|
21 | 21 | Current subpackges |
|
22 | 22 | ================== |
|
23 | 23 | |
|
24 | 24 | IPython currently has the following sub-packages: |
|
25 | 25 | |
|
26 | 26 | * :mod:`IPython.config` |
|
27 | 27 | |
|
28 | 28 | * :mod:`IPython.Extensions` |
|
29 | 29 | |
|
30 | 30 | * :mod:`IPython.external` |
|
31 | 31 | |
|
32 | 32 | * :mod:`IPython.frontend` |
|
33 | 33 | |
|
34 | 34 | * :mod:`IPython.gui` |
|
35 | 35 | |
|
36 | 36 | * :mod:`IPython.kernel` |
|
37 | 37 | |
|
38 | 38 | * :mod:`IPython.testing` |
|
39 | 39 | |
|
40 | 40 | * :mod:`IPython.tests` |
|
41 | 41 | |
|
42 | 42 | * :mod:`IPython.tools` |
|
43 | 43 | |
|
44 | 44 | * :mod:`IPython.UserConfig` |
|
45 | 45 | |
|
46 | 46 | New Subpackages to be created |
|
47 | 47 | ============================= |
|
48 | 48 | |
|
49 | 49 | We propose to create the following new sub-packages: |
|
50 | 50 | |
|
51 | 51 | * :mod:`IPython.core`. This sub-package will contain the core of the IPython |
|
52 | 52 | interpreter, but none of its extended capabilities. |
|
53 | 53 | |
|
54 | 54 | * :mod:`IPython.lib`. IPython has many extended capabilities that are not part |
|
55 | 55 | of the IPython core. These things will go here. Any better names than |
|
56 | 56 | :mod:`IPython.lib`? |
|
57 | 57 | |
|
58 | 58 | * :mod:`IPython.python`. This sub-package will contain anything that might |
|
59 | 59 | eventually be found in the Python standard library, like things in |
|
60 | 60 | :mod:`genutils`. Each sub-module in this sub-package should contain functions |
|
61 | 61 | and classes that serve a single purpose. Similar in purpose to |
|
62 | 62 | :mod:`twisted.python`. Could also call this :mod:`IPython.tools`, |
|
63 | 63 | :mod:`IPython.utils` or something similar. |
|
64 | 64 | |
|
65 | 65 | * :mod:`IPython.sandbox`. This is for code that is untested and/or rotting and |
|
66 | 66 | needs to be removed from IPython. Eventually all this code will either i) be |
|
67 | revived with tests and docs and re-included into IPython or 2) be removed from | |
|
68 | IPython proper, but put into a separate top-level (not IPython) package that we | |
|
69 | keep around. | |
|
67 | revived by someone willing to maintain it with tests and docs and | |
|
68 | re-included into IPython or 2) be removed from IPython proper, but put into | |
|
69 | a separate top-level (not IPython) package that we keep around. | |
|
70 | 70 | |
|
71 | 71 | Where things will be moved |
|
72 | 72 | ========================== |

|
205 | 205 | Other things |
|
206 | 206 | ============ |
|
207 | 207 | |
|
208 | 208 | When these files are moved around, a number of other things will happen at the same time: |
|
209 | 209 | |
|
210 | 210 | 1. Test files will be created for each module in IPython. Minimally, all |
|
211 | 211 | modules will be imported as a part of the test. This will serve as a |
|
212 | 212 | test of the module reorganization. These tests will be put into new |
|
213 | 213 | :file:`tests` subdirectories that each package will have. |
|
214 | 214 | |
|
215 | 215 | 2. PyFlakes and other code checkers will be run to look for problems. |
|
216 | 216 | |
|
217 | 217 | 3. Modules will be renamed to comply with PEP 8 naming conventions: all |
|
218 | 218 | lowercase and no special characters like ``-`` or ``_``. |
|
219 | 219 | |
|
220 | 220 | 4. Existing tests will be moved to the appropriate :file:`tests` |
|
221 | 221 | subdirectories. |
