Opening files with Windows system viewer under WSL

[hendrikbursian]

Can this functionality be implemented utilising API?
no

Is your feature request related to a problem? Please describe.
Under WSL I cannot and don't want to open files like a PDF within the WSL instance.

Describe the solution you'd like
I would like nvim_tree to open the files with the wslview utility analog to how the vim.ui.open api does it.

Describe alternatives you've considered
For now I just do require('nvim-tree.actions.node.system-open').config.system_open.cmd = 'wslview'

Additional context
Maybe the nvim-tree.actions.node.system-open function can make use of vim.ui.open itself.

Thank you for the plugin. I use it frequently and I am very happy how it turned out.

vim.ui.open is rather useful. It will greatly reduce complexity and improve compatibility. Unfortunately it's not yet been released... #2430

In the interests of keeping things generic and flexible, perhaps we might allow system_open to take a function in, in the same manner as view.width. The user can then decide how top open based on, say, file name.

[alex-courtis]

You could do something like this to replace system open:

  vim.keymap.set("n", "?", function()
    local api = require("nvim-tree.api")
    local node = api.tree.get_node_under_cursor()
    -- decide what to do with node.absolute_path
  end, opts("something something open"))

That might be preferable; changing system_open will be obsolete once ui.open is ready.

Closing this one. Proper solution will come with #2430
