1 | 1 | """Completion for IPython. |
|
2 | 2 | |
|
3 | 3 | This module started as fork of the rlcompleter module in the Python standard |
|
4 | 4 | library. The original enhancements made to rlcompleter have been sent |
|
5 | 5 | upstream and were accepted as of Python 2.3, |
|
6 | 6 | |
|
7 | 7 | This module now support a wide variety of completion mechanism both available |
|
8 | 8 | for normal classic Python code, as well as completer for IPython specific |
|
9 | 9 | Syntax like magics. |
|
10 | 10 | |
|
11 | 11 | Latex and Unicode completion |
|
12 | 12 | ============================ |
|
13 | 13 | |
|
14 | 14 | IPython and compatible frontends not only can complete your code, but can help |
|
15 | 15 | you to input a wide range of characters. In particular we allow you to insert |
|
16 | 16 | a unicode character using the tab completion mechanism. |
|
17 | 17 | |
|
18 | 18 | Forward latex/unicode completion |
|
19 | 19 | -------------------------------- |
|
20 | 20 | |
|
21 | 21 | Forward completion allows you to easily type a unicode character using its latex |
|
22 | 22 | name, or unicode long description. To do so type a backslash follow by the |
|
23 | 23 | relevant name and press tab: |
|
24 | 24 | |
|
25 | 25 | |
|
26 | 26 | Using latex completion: |
|
27 | 27 | |
|
28 | 28 | .. code:: |
|
29 | 29 | |
|
30 | 30 | \\alpha<tab> |
|
31 | 31 | Ξ± |
|
32 | 32 | |
|
33 | 33 | or using unicode completion: |
|
34 | 34 | |
|
35 | 35 | |
|
36 | 36 | .. code:: |
|
37 | 37 | |
|
38 | 38 | \\GREEK SMALL LETTER ALPHA<tab> |
|
39 | 39 | Ξ± |
|
40 | 40 | |
|
41 | 41 | |
|
42 | 42 | Only valid Python identifiers will complete. Combining characters (like arrow or |
|
43 | 43 | dots) are also available, unlike latex they need to be put after the their |
|
44 | 44 | counterpart that is to say, ``F\\\\vec<tab>`` is correct, not ``\\\\vec<tab>F``. |
|
45 | 45 | |
|
46 | 46 | Some browsers are known to display combining characters incorrectly. |
|
47 | 47 | |
|
48 | 48 | Backward latex completion |
|
49 | 49 | ------------------------- |
|
50 | 50 | |
|
51 | 51 | It is sometime challenging to know how to type a character, if you are using |
|
52 | 52 | IPython, or any compatible frontend you can prepend backslash to the character |
|
53 | 53 | and press :kbd:`Tab` to expand it to its latex form. |
|
54 | 54 | |
|
55 | 55 | .. code:: |
|
56 | 56 | |
|
57 | 57 | \\Ξ±<tab> |
|
58 | 58 | \\alpha |
|
59 | 59 | |
|
60 | 60 | |
|
61 | 61 | Both forward and backward completions can be deactivated by setting the |
|
62 | 62 | :std:configtrait:`Completer.backslash_combining_completions` option to |
|
63 | 63 | ``False``. |
|
64 | 64 | |
|
65 | 65 | |
|
66 | 66 | Experimental |
|
67 | 67 | ============ |
|
68 | 68 | |
|
69 | 69 | Starting with IPython 6.0, this module can make use of the Jedi library to |
|
70 | 70 | generate completions both using static analysis of the code, and dynamically |
|
71 | 71 | inspecting multiple namespaces. Jedi is an autocompletion and static analysis |
|
72 | 72 | for Python. The APIs attached to this new mechanism is unstable and will |
|
73 | 73 | raise unless use in an :any:`provisionalcompleter` context manager. |
|
74 | 74 | |
|
75 | 75 | You will find that the following are experimental: |
|
76 | 76 | |
|
77 | 77 | - :any:`provisionalcompleter` |
|
78 | 78 | - :any:`IPCompleter.completions` |
|
79 | 79 | - :any:`Completion` |
|
80 | 80 | - :any:`rectify_completions` |
|
81 | 81 | |
|
82 | 82 | .. note:: |
|
83 | 83 | |
|
84 | 84 | better name for :any:`rectify_completions` ? |
|
85 | 85 | |
|
86 | 86 | We welcome any feedback on these new API, and we also encourage you to try this |
|
87 | 87 | module in debug mode (start IPython with ``--Completer.debug=True``) in order |
|
88 | 88 | to have extra logging information if :any:`jedi` is crashing, or if current |
|
89 | 89 | IPython completer pending deprecations are returning results not yet handled |
|
90 | 90 | by :any:`jedi` |
|
91 | 91 | |
|
92 | 92 | Using Jedi for tab completion allow snippets like the following to work without |
|
93 | 93 | having to execute any code: |
|
94 | 94 | |
|
95 | 95 | >>> myvar = ['hello', 42] |
|
96 | 96 | ... myvar[1].bi<tab> |
|
97 | 97 | |
|
98 | 98 | Tab completion will be able to infer that ``myvar[1]`` is a real number without |
|
99 | 99 | executing almost any code unlike the deprecated :any:`IPCompleter.greedy` |
|
100 | 100 | option. |
|
101 | 101 | |
|
102 | 102 | Be sure to update :any:`jedi` to the latest stable version or to try the |
|
103 | 103 | current development version to get better completions. |
|
104 | 104 | |
|
105 | 105 | Matchers |
|
106 | 106 | ======== |
|
107 | 107 | |
|
108 | 108 | All completions routines are implemented using unified *Matchers* API. |
|
109 | 109 | The matchers API is provisional and subject to change without notice. |
|
110 | 110 | |
|
111 | 111 | The built-in matchers include: |
|
112 | 112 | |
|
113 | 113 | - :any:`IPCompleter.dict_key_matcher`: dictionary key completions, |
|
114 | 114 | - :any:`IPCompleter.magic_matcher`: completions for magics, |
|
115 | 115 | - :any:`IPCompleter.unicode_name_matcher`, |
|
116 | 116 | :any:`IPCompleter.fwd_unicode_matcher` |
|
117 | 117 | and :any:`IPCompleter.latex_name_matcher`: see `Forward latex/unicode completion`_, |
|
118 | 118 | - :any:`back_unicode_name_matcher` and :any:`back_latex_name_matcher`: see `Backward latex completion`_, |
|
119 | 119 | - :any:`IPCompleter.file_matcher`: paths to files and directories, |
|
120 | 120 | - :any:`IPCompleter.python_func_kw_matcher` - function keywords, |
|
121 | 121 | - :any:`IPCompleter.python_matches` - globals and attributes (v1 API), |
|
122 | 122 | - ``IPCompleter.jedi_matcher`` - static analysis with Jedi, |
|
123 | 123 | - :any:`IPCompleter.custom_completer_matcher` - pluggable completer with a default |
|
124 | 124 | implementation in :any:`InteractiveShell` which uses IPython hooks system |
|
125 | 125 | (`complete_command`) with string dispatch (including regular expressions). |
|
126 | 126 | Differently to other matchers, ``custom_completer_matcher`` will not suppress |
|
127 | 127 | Jedi results to match behaviour in earlier IPython versions. |
|
128 | 128 | |
|
129 | 129 | Custom matchers can be added by appending to ``IPCompleter.custom_matchers`` list. |
|
130 | 130 | |
|
131 | 131 | Matcher API |
|
132 | 132 | ----------- |
|
133 | 133 | |
|
134 | 134 | Simplifying some details, the ``Matcher`` interface can described as |
|
135 | 135 | |
|
136 | 136 | .. code-block:: |
|
137 | 137 | |
|
138 | 138 | MatcherAPIv1 = Callable[[str], list[str]] |
|
139 | 139 | MatcherAPIv2 = Callable[[CompletionContext], SimpleMatcherResult] |
|
140 | 140 | |
|
141 | 141 | Matcher = MatcherAPIv1 | MatcherAPIv2 |
|
142 | 142 | |
|
143 | 143 | The ``MatcherAPIv1`` reflects the matcher API as available prior to IPython 8.6.0 |
|
144 | 144 | and remains supported as a simplest way for generating completions. This is also |
|
145 | 145 | currently the only API supported by the IPython hooks system `complete_command`. |
|
146 | 146 | |
|
147 | 147 | To distinguish between matcher versions ``matcher_api_version`` attribute is used. |
|
148 | 148 | More precisely, the API allows to omit ``matcher_api_version`` for v1 Matchers, |
|
149 | 149 | and requires a literal ``2`` for v2 Matchers. |
|
150 | 150 | |
|
151 | 151 | Once the API stabilises future versions may relax the requirement for specifying |
|
152 | 152 | ``matcher_api_version`` by switching to :any:`functools.singledispatch`, therefore |
|
153 | 153 | please do not rely on the presence of ``matcher_api_version`` for any purposes. |
|
154 | 154 | |
|
155 | 155 | Suppression of competing matchers |
|
156 | 156 | --------------------------------- |
|
157 | 157 | |
|
158 | 158 | By default results from all matchers are combined, in the order determined by |
|
159 | 159 | their priority. Matchers can request to suppress results from subsequent |
|
160 | 160 | matchers by setting ``suppress`` to ``True`` in the ``MatcherResult``. |
|
161 | 161 | |
|
162 | 162 | When multiple matchers simultaneously request surpression, the results from of |
|
163 | 163 | the matcher with higher priority will be returned. |
|
164 | 164 | |
|
165 | 165 | Sometimes it is desirable to suppress most but not all other matchers; |
|
166 | 166 | this can be achieved by adding a list of identifiers of matchers which |
|
167 | 167 | should not be suppressed to ``MatcherResult`` under ``do_not_suppress`` key. |
|
168 | 168 | |
|
169 | 169 | The suppression behaviour can is user-configurable via |
|
170 | 170 | :std:configtrait:`IPCompleter.suppress_competing_matchers`. |

2986 | 2986 | Text to perform the completion on. If not given, the line buffer |
|
2987 | 2987 | is split using the instance's CompletionSplitter object. |
|
2988 | 2988 | line_buffer : string, optional |
|
2989 | 2989 | If not given, the completer attempts to obtain the current line |
|
2990 | 2990 | buffer via readline. This keyword allows clients which are |
|
2991 | 2991 | requesting for text completions in non-readline contexts to inform |
|
2992 | 2992 | the completer of the entire text. |
|
2993 | 2993 | cursor_pos : int, optional |
|
2994 | 2994 | Index of the cursor in the full line buffer. Should be provided by |
|
2995 | 2995 | remote frontends where kernel has no access to frontend state. |
|
2996 | 2996 | |
|
2997 | 2997 | Returns |
|
2998 | 2998 | ------- |
|
2999 | 2999 | Tuple of two items: |
|
3000 | 3000 | text : str |

3 | 3 | Pdb debugger class. |
|
4 | 4 | |
|
5 | 5 | |
|
6 | 6 | This is an extension to PDB which adds a number of new features. |
|
7 | 7 | Note that there is also the `IPython.terminal.debugger` class which provides UI |
|
8 | 8 | improvements. |
|
9 | 9 | |
|
10 | 10 | We also strongly recommend to use this via the `ipdb` package, which provides |
|
11 | 11 | extra configuration options. |
|
12 | 12 | |
|
13 | 13 | Among other things, this subclass of PDB: |
|
14 | 14 | - supports many IPython magics like pdef/psource |
|
15 | 15 | - hide frames in tracebacks based on `__tracebackhide__` |
|
16 | 16 | - allows to skip frames based on `__debuggerskip__` |
|
17 | 17 | |
|
18 | 18 | The skipping and hiding frames are configurable via the `skip_predicates` |
|
19 | 19 | command. |
|
20 | 20 | |
|
21 | 21 | By default, frames from readonly files will be hidden, frames containing |
|
22 | 22 | ``__tracebackhide__=True`` will be hidden. |
|
23 | 23 | |
|
24 | 24 | Frames containing ``__debuggerskip__`` will be stepped over, frames who's parent |
|
25 | 25 | frames value of ``__debuggerskip__`` is ``True`` will be skipped. |
|
26 | 26 | |
|
27 | 27 | >>> def helpers_helper(): |
|
28 | 28 | ... pass |
|
29 | 29 | ... |
|
30 | 30 | ... def helper_1(): |
|
31 | 31 | ... print("don't step in me") |
|
32 | 32 | ... helpers_helpers() # will be stepped over unless breakpoint set. |
|
33 | 33 | ... |
|
34 | 34 | ... |
|
35 | 35 | ... def helper_2(): |
|
36 | 36 | ... print("in me neither") |
|
37 | 37 | ... |
|
38 | 38 | |
|
39 | 39 | One can define a decorator that wraps a function between the two helpers: |
|
40 | 40 | |
|
41 | 41 | >>> def pdb_skipped_decorator(function): |
|
42 | 42 | ... |
|
43 | 43 | ... |
|
44 | 44 | ... def wrapped_fn(*args, **kwargs): |
|
45 | 45 | ... __debuggerskip__ = True |
|
46 | 46 | ... helper_1() |
|
47 | 47 | ... __debuggerskip__ = False |
|
48 | 48 | ... result = function(*args, **kwargs) |
|
49 | 49 | ... __debuggerskip__ = True |
|
50 | 50 | ... helper_2() |
|
51 | 51 | ... # setting __debuggerskip__ to False again is not necessary |
|
52 | 52 | ... return result |
|
53 | 53 | ... |
|
54 | 54 | ... return wrapped_fn |
|
55 | 55 | |
|
56 | 56 | When decorating a function, ipdb will directly step into ``bar()`` by |
|
57 | 57 | default: |
|
58 | 58 | |
|
59 | 59 | >>> @foo_decorator |
|
60 | 60 | ... def bar(x, y): |
|
61 | 61 | ... return x * y |
|
62 | 62 | |
|
63 | 63 | |
|
64 | 64 | You can toggle the behavior with |
|
65 | 65 | |
|
66 | 66 | ipdb> skip_predicates debuggerskip false |
|
67 | 67 | |
|
68 | 68 | or configure it in your ``.pdbrc`` |

3 | 3 | Verbose and colourful traceback formatting. |
|
4 | 4 | |
|
5 | 5 | **ColorTB** |
|
6 | 6 | |
|
7 | 7 | I've always found it a bit hard to visually parse tracebacks in Python. The |
|
8 | 8 | ColorTB class is a solution to that problem. It colors the different parts of a |
|
9 | 9 | traceback in a manner similar to what you would expect from a syntax-highlighting |
|
10 | 10 | text editor. |
|
11 | 11 | |
|
12 | 12 | Installation instructions for ColorTB:: |
|
13 | 13 | |
|
14 | 14 | import sys,ultratb |
|
15 | 15 | sys.excepthook = ultratb.ColorTB() |
|
16 | 16 | |
|
17 | 17 | **VerboseTB** |
|
18 | 18 | |
|
19 | 19 | I've also included a port of Ka-Ping Yee's "cgitb.py" that produces all kinds |
|
20 | 20 | of useful info when a traceback occurs. Ping originally had it spit out HTML |
|
21 | 21 | and intended it for CGI programmers, but why should they have all the fun? I |
|
22 | 22 | altered it to spit out colored text to the terminal. It's a bit overwhelming, |
|
23 | 23 | but kind of neat, and maybe useful for long-running programs that you believe |
|
24 | 24 | are bug-free. If a crash *does* occur in that type of program you want details. |
|
25 | 25 | Give it a shot--you'll love it or you'll hate it. |
|
26 | 26 | |
|
27 | 27 | .. note:: |
|
28 | 28 | |
|
29 | 29 | The Verbose mode prints the variables currently visible where the exception |
|
30 | 30 | happened (shortening their strings if too long). This can potentially be |
|
31 | 31 | very slow, if you happen to have a huge data structure whose string |
|
32 | 32 | representation is complex to compute. Your computer may appear to freeze for |
|
33 | 33 | a while with cpu usage at 100%. If this occurs, you can cancel the traceback |
|
34 | 34 | with Ctrl-C (maybe hitting it more than once). |
|
35 | 35 | |
|
36 | 36 | If you encounter this kind of situation often, you may want to use the |
|
37 | 37 | Verbose_novars mode instead of the regular Verbose, which avoids formatting |
|
38 | 38 | variables (but otherwise includes the information and context given by |
|
39 | 39 | Verbose). |
|
40 | 40 | |
|
41 | 41 | .. note:: |
|
42 | 42 | |
|
43 | 43 | The verbose mode print all variables in the stack, which means it can |
|
44 | 44 | potentially leak sensitive information like access keys, or unencrypted |
|
45 | 45 | password. |
|
46 | 46 | |
|
47 | 47 | Installation instructions for VerboseTB:: |
|
48 | 48 | |
|
49 | 49 | import sys,ultratb |
|
50 | 50 | sys.excepthook = ultratb.VerboseTB() |
|
51 | 51 | |
|
52 | 52 | Note: Much of the code in this module was lifted verbatim from the standard |
|
53 | 53 | library module 'traceback.py' and Ka-Ping Yee's 'cgitb.py'. |
|
54 | 54 | |
|
55 | 55 | Color schemes |
|
56 | 56 | ------------- |
|
57 | 57 | |
|
58 | 58 | The colors are defined in the class TBTools through the use of the |
|
59 | 59 | ColorSchemeTable class. Currently the following exist: |
|
60 | 60 | |
|
61 | 61 | - NoColor: allows all of this module to be used in any terminal (the color |
|
62 | 62 | escapes are just dummy blank strings). |
|
63 | 63 | |
|
64 | 64 | - Linux: is meant to look good in a terminal like the Linux console (black |
|
65 | 65 | or very dark background). |
|
66 | 66 | |
|
67 | 67 | - LightBG: similar to Linux but swaps dark/light colors to be more readable |
|
68 | 68 | in light background terminals. |
|
69 | 69 | |
|
70 | 70 | - Neutral: a neutral color scheme that should be readable on both light and |
|
71 | 71 | dark background |
|
72 | 72 | |
|
73 | 73 | You can implement other color schemes easily, the syntax is fairly |
|
74 | 74 | self-explanatory. Please send back new schemes you develop to the author for |
|
75 | 75 | possible inclusion in future releases. |
