|
|||
63 | This is a workaround for a weird IPython/Prompt_toolkit behavior, |
|
|||
64 | that can be removed once we rely on a slightly more recent prompt_toolkit |
|
|||
65 | version (likely > 1.0.3). So this can likely be removed in IPython 6.0 |
|
|||
66 |
|
||||
67 | cf https://github.com/ipython/ipython/issues/9658 |
|
|||
68 | and https://github.com/jonathanslenders/python-prompt-toolkit/pull/328 |
|
|||
69 |
|
||||
70 | The bug is due to the fact that in PTK the completer will reinvoke itself |
|
|||
71 | after trying to completer to the longuest common prefix of all the |
|
|||
72 | completions, unless only one completion is available. |
|
|||
73 |
|
||||
74 | This logic is faulty if the completion ends with space, which can happen in |
|
|||
75 | case like:: |
|
|||
76 |
|
||||
77 | from foo import im<ta> |
|
|||
78 |
|
||||
79 | which only matching completion is `import `. Note the leading space at the |
|
|||
80 | end. So leaving a space at the end is a reasonable request, but for now |
|
|||
81 | we'll strip it. |
