Hi,
Traditionally, readline-style applications complete the longest common
prefix when pressing tab once, and only when pressing tab again they
actually show the available options.
I changed fish to do both things when pressing tab only once. IPython
does the same.
Since this is a core feature and we don't want to alienate people who
have acquired a muscle memory of the old behavior, please let me know
if you have any concerns.
The patch [1] is already in master, so you can easily try it.
Also refer to the motivating issue [2] on GitHub.
Example: create some files with a common prefix,
$ touch common-prefix-(seq 100)
then type "cat comm<TAB>". Previously, fish would only insert
"common-prefix-". Now it also shows the file names, but caps the to
pager to four lines, so this seems fine.
Cheers,
Johannes
