I am writing a completion function where at some point I use _files -W $somevar -/ to complete sub directories of $somevar. For simplicity of the question let's say it's $HOME/.local/lib and I have subdirectories for different python versions in there and actually want to complete python versions for which I have a $HOME/.local/lib/ directory:
_files -W $HOME/.local/lib -/
and the directory tree looks something like
.local
├── lib
│ ├── python3.5
│ │ └── site-packages
│ │ ├── somepackage
│ │ ├── somepackage-1.0.1-py2.7.egg-info
│ │ ├── someotherpackage
│ │ └── someotherpackage-1.0.11-py2.7.egg-info
│ ├── python3.6
│ │ └── site-packages
│ │ ├── somepackage
│ │ │ └── __pycache__
│ │ ├── somepackage-0.1-py3.6.egg-info
│ │ ├── someotherpackage
│ │ │ └── __pycache__
│ │ ├── someotherpackage-2018.4.16.dist-info
...
If I use the above completion for mycommand <TAB> the suggestions are now python3.5/ and python3.6/ with the trailing slash inserted by the tab completion and once I picked one version, the completion further suggest python3.5/site-package. This is insofar correct behaviour as these are actually existing directories. For my use case, I don't want to go down the directory three, but only complete directories directly in $HOME/.local/lib. Is there an easy way to complete directories without completing into them with builtin completion functions? Or should I use glob expressions $HOME/.local/lib/*(/) and strip off the parts that I don't want?
