|
8 | ============ | |||
|
9 | ||||
|
10 | IPython 7.15 brings a number of bug fixes and user facing improvements. | |||
|
11 | ||||
|
12 | Noticeable changes: | |||
|
13 | ------------------- | |||
|
14 | ||||
|
15 | - Long completion name have better elision in terminal :ghpull:`12284` | |||
|
16 | - We've started to test on Python 3.9 :ghpull:`12307` and fix some errors. | |||
|
17 | - Hi DPI scaling of figures when using qt eventloop :ghpull:`12314` | |||
|
18 | - Document the ability to have systemwide configuration for IPython. | |||
|
19 | :ghpull:`12328` | |||
|
20 | - Fix issues with input autoformatting :ghpull:`12336` | |||
|
21 | ||||
|
22 | ||||
|
23 | Highlighted features | |||
|
24 | -------------------- | |||
|
25 | ||||
|
26 | Increase Tab Completion Menu Height | |||
|
27 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |||
|
28 | ||||
|
29 | In terminal IPython it is possible to increase the hight of the tab-completion | |||
|
30 | menu. To do so set the value of | |||
|
31 | :configtrait:`TerminalInteractiveShell.space_for_menu`, this will reserve more | |||
|
32 | space at the bottom of the screen for various kind of menus in IPython including | |||
|
33 | tab completion and searching in history. | |||
|
34 | ||||
|
35 | Autoformat Code in the terminal | |||
|
36 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |||
|
37 | ||||
|
38 | If you have a preferred code formatter, you can configure IPython to | |||
|
39 | reformat your code. Set the value of | |||
|
40 | :configtrait:`TerminalInteractiveShell.autoformatter` to for example ``'black'`` | |||
|
41 | and IPython will auto format your code when possible. | |||
