How can I disable filename abbreviations in the results of tab-autocompletion?

[cxrodgers]

Note 1: This is not the same tab-completion bug for which many issues have already been opened (the one where a massive number of objects from the global namespace are displayed). This issue specifically has to do with unwanted abbreviation of filename paths. I haven't yet found any other reports of this issue.

Note 2: I also posted this to stackoverflow but am posting again here since I didn't receive a response there yet.

Issue begins now:
When I use tab-autocompletion to complete file paths in ipython, the results are not very useful because it abbreviates each path to just the first and last characters, separated by an ellipsis.

This is the result from pressing tab when there are 5 matches, each about 60 characters long.

In [2]: ls /home/jack/mnt/nas2_home/misc/201912
/h…s/ /h…a/ /h…n/ /h…o/ /h…o/

These are the desired results, obtained with a previous version (see below):

In [2]: ls /home/jack/mnt/nas2_home/misc/201912
/home/jack/mnt/nas2_home/misc/20191207_PoseTF_new_sessions/ 
/home/jack/mnt/nas2_home/misc/20191209_adrian_data/         
/home/jack/mnt/nas2_home/misc/20191217_PoseTF_curation/     
/home/jack/mnt/nas2_home/misc/20191230_PoseTF_fullvideo/    
/home/jack/mnt/nas2_home/misc/20191231_PoseTF_fullvideo/

I used 'readlinelike' autocompletions, but the results are the same using the 'column' or 'multicolumn' options for c.TerminalInteractiveShell.display_completions. I renamed my entire .ipython directory and created a new profile with all the default settings, so I don't think it is any weird setting that I have.

Here are the installed versions of some relevant modules:

ipython                   7.11.1           py37h39e3cac_0  
jedi                      0.16.0                   py37_0  
prompt_toolkit            3.0.3                      py_0  
python                    3.7.6                h0371630_2  

If I downgrade to ipython=5.8.0 and prompt_toolkit=1.0.15, I get the desired behavior. So this is a good workaround for now, but I'd like to be able to stay up to date, or at least understand how to configure this behavior.

thanks!

Hum, my guess is this will be in IPython/terminal/ptutils.py, function _elide(), it is suppose to elide only in between slashes; but seem not to.

It should not be too hard to fix (if that's actually the reason); or at least to test this function in isolation.

Thanks for the report.

Thanks for the info! I wonder if the problem is that the directory search is unexpectedly returning terminal slashes.

This replicates the current, undesired behavior:

In [12]: IPython.terminal.ptutils._elide('/home/jack/mnt/nas2_home/misc/20200130_unit_db/')
Out[12]: '/h…b/'

This would be better:

In [13]: IPython.terminal.ptutils._elide('/home/jack/mnt/nas2_home/misc/20200130_unit_db')
Out[13]: '/h…c/20200130_unit_db'

Is there a way to modify min_elide using configuratiob files?

Hi, if this problem is still open, can I work on it?

[cxrodgers]

@Inception95 I don't know who gets to decide who works on things, but as far as I'm concerned you can. Let me know if you want me to provide more debugging info

[Carreau]

Anybody can work on anything they like. I'll do my best to review PRs when I have time. Thanks for expressing your interest!
