Please describe the problem you're trying to solve

I would like to improve the Yazi toggle feature of yazi.nvim a bit. This feature remembers where yazi was last closed, the file that was most recently hovered in the previous session. The command simply opens yazi with the hovered path as input.

However, this seems to work nicely for files but for directories the behaviour is slightly different:

• when a file is given as input (yazi /tmp/file), yazi is opened in /tmp/, hovering file
• when a directory is given as input (yazi /tmp/), yazi is opened in /tmp/, hovering the first file in that directory
  • in this case, I would like to open yazi in /, hovering /tmp/

Would you be willing to contribute this feature?

• Yes, I'll give it a shot

Describe the solution you'd like

Here are some ideas:

1. maybe a new cli argument --hover /tmp/file that would open yazi in /, hovering /tmp/

• this might be difficult to make work for tabs that are opened at startup (which are given as multiple files, e.g. yazi /tmp/file /etc/ /dev/)

2. introduce a breaking change to the current behaviour

• not sure if ideal to make it the default as the current behaviour is sometimes useful

3. add a new DDS event dds-hover (like dds-cd in https://yazi-rs.github.io/docs/dds/#dds.lua) that is similarly able to hover the specified file

Additional context

No response

Validations

• I have searched the existing issues
• The latest nightly build of Yazi doesn't already have this feature

I've been thinking about it, and I think I have an answer now.

We can add a new ya emit subcommand that's just used to trigger built-in commands (instead of DDS events). So ya pub dds-reveal --str "/tmp" could be written as ya emit reveal "/tmp".

Basically, reveal "/tmp" would match the format in keymap.toml for run, meaning we could also use any named parameters, like ya emit plugin --sync "my-plugin".

I'll try to implement it in the next few weeks.
