Expand candidate without closing the completion prompt

[musjj]

Is your feature request related to a problem? Please describe

With the completion menu, you can't expand a candidate without closing the completion or moving into the selected directory. This feels unintuitive compared to the completion methods found in other editors/IDEs.

Will you be willing to contribute this feature?

• Yes, I will try to implement it

Describe the solution you'd like

We should be able to expand a candidate without closing the window. To make this work, the first candidate should also not be automatically selected (which is the current default behavior).

For example:

/foo|
  foobar
  foo
  foobaz/

We can then press <Tab> a few times:

/foobar|
> foobar
  foo
  foobaz/

/foo|
  foobar
> foo
  foobaz/

/foobaz|
  foobar
  foo
> foobaz/

Then we can add / to enter into the subdirectory:

/foobaz/|
  child
  items

I have considered this approach, but it only allows "prefix matching". If there are multiple filenames in the directory with the same prefix, such as Cargo.toml and Cargo.lock, users would need to repeatedly switch between them using the <Tab> key.

If users want to modify the search keyword to make the results more accurate, they would need to cycle back to the first option or use a special "cancel key" to cancel the selection, which adds complexity.

In the current way, we can extend it by implementing fuzzy matching - "ct" matches "Cargo.toml", "cl" matches "Cargo.lock", and users only need to press <Tab> once.

I'm not sure what you mean. Isn't this how it currently works (except that the first candidate is automatically selected)?

If users want to modify the search keyword to make the results more accurate, they would need to cycle back to the first option or use a special "cancel key" to cancel the selection, which adds complexity.

If the user wants to make the results more accurate, they can just keep on typing to narrow down the results before cycling through the candidates. That's how I usually do it in other editors. Actually, this also doesn't sound any different from how it currently works, can you clarify?

Fuzzy completion would definitely be an awesome addition though.

Current autocomplete in Yazi is not just "prefix matching". If we implement the issue's approach would lead to:

/go|
  Cargo.toml
  Cargo.lock

then press <Tab>:

/Cargo.toml|
> Cargo.toml
  Cargo.lock

press <Tab>

/Cargo.lock|
  Cargo.toml
> Cargo.lock

press <Tab> again:

/go|
  Cargo.toml
  Cargo.lock

It changed from go to Cargo.toml, which is quite strange. I haven't seen this behavior in any editor/shell I've used. In contrast, Neovim is like this:

nvim.mp4

In zsh like this:

zsh.mp4

Their candidates start with ma or da that's user input.

Hmmm, I don't think it's strange. This is how my neovim's nvim-cmp works (I think it's pretty close to the default):
