I do not understand how to call defaultAction or add input

Warning: I will close the issue without the minimal init.vim and the reproduction instructions.

Problems summary

Hi. I am migrating from Denite and I get the general flow of how this new plugin works, but I cannot figure out how to accomplish two things.

1) How to define and call actions in the init.vim file? Currently I can pull up the ddu buffer, but then I have no way to open files. 2) How to refine input with the fuzzy finder? for instance if 'file_rec' pulls up too many files, how can I refine my search after the buffer comes up?

Expected

I have looked through the documentation, but I do not see any examples of how to do this.

I still have a remaining problem though. Now when I call the defaultAction, I get an error which reads

[ddu] Invalid kind: file

[jeffwillette]

I see now that the 'kind' is actually another module which needs to be installed to implement file operations. I did not know everything would be so modular down to this micro level. Sorry for the noise, I hope this thread helps someone in the future.

This is what I needed to install https://github.com/Shougo/ddu-kind-file

[Shougo]

Yes. All features are modular in ddu.vim.

[Shougo]

For those who may find this later. I found the examples in the documentation for the ff UI and not in the main ddu documentation.

Because, it is UI feature instead of ddu.vim.

[Shougo]

You need to read sources documentation. For example, in ddu-source-file:

## Required

### denops.vim

https://github.com/vim-denops/denops.vim

### ddu.vim

https://github.com/Shougo/ddu.vim

### ddu-kind-file

https://github.com/Shougo/ddu-kind-file

The dependency is already documented.
