[issue27609] IDLE completions: format, factor, and fix

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Normally, tab completion works for attributes (after '.' and a possible prefix) 
and files (after os.sep and a possible prefix).  Unique matches to prefixes are 
immediately selected, as for undotted module names.  After changing the 
completion wait time and before restarting, this is disabled and tab adds 
spaces instead.  This need a new issue and fix.

fetch_completions code could stand some refactoring.  The test should be split 
at least between attrs and files.

#37765 Include keywords in ''(__main__) list.

## Annotate completion list, at least as an option, with 'keyword' or 
class, possibly prefixed with 'built-in', so 'built-in function', 'function', 
and so on.

#37766 revise fetch_completions, add htest

Terry J. Reedy  added the comment:

In re-verifying #27675, the color bug seems to be gone.  The completion bug is 
still here, at least on Windows.

It would be good to sort the issues by whether they appear to affect 
autocomplete.py or autocomplete_w.py or both.

[issue27609] IDLE completions: format, factor, and fix

[Terry J. Reedy]

New submission from Terry J. Reedy:

IDLE completions are currently implemented in two files: autocomplete.py and 
autocomplete_w.py.  (Before 3.6, these were AutoComplete.py and 
AutoCompleteWindow.py.) The first handles 'open' events, decideds whether to 
open a window, and gathers possible completions.  The second open a popup and 
works with the sorted list of possible completions. There are several tracker 
issues already.

#15786 Code completion problems with mouse and .
  These lead to freezes on on Mac.  Severity: bad; prioriy: high.
#16198 Tabbing in string brings up completion when it should not.
#17238 Enhance import statement completion.
#18766 Add completions for un-imported modules (by importing).
#18903 File completions are case sensitive, should not be on Windows.
#21261 Complete dictionary keys.
#22554 Popup window for names also.  

#27099 Convert autocomplete to normal feature, along with other 'extensions'.  
Add delay to current tab.  Negative delay should disable auto-popups.
#27534 Move objects needed by run to run.py and import from there.

There are more that are not on the tracker.  Patches may be attached here or to 
new issues.

A. Use PEP8 style.  1.'return None' when there are non-None returns. 2. 
Docstrings for all functions.
B. Merge autocomplete_w into autocomplete.  This was anticipated in the 
renaming.  #27534 should be done first if possible, or soon after.
C. Refactor.  1 #27534.  2. Put list and scrollbar in Frame?  For future 
single-window IDLE?  This might make testing easier. 3. Anything else making 
tests easier.
D. Make completions work for number literals ("1 .") as well a string literals 
("'a'.").
E?. Make completions work with Entry as well as Multicall wrapping text?  Need 
use case first.  Load Modules may need own code.

Question: Why does 'dooneevent' appear in 2.x code and not 3.x code?

Tests: The currently only for a subset of autocomplete methods.  There are none 
for the buggy window.

First, a patch for A.1, return None.
