How to chain fzf commands?

[elenapan]

For example, I would like to first select a directory from project_list and then start a file search in that directory.

How would I go about implementing this?

The following snippet does not work as expected.

local project_list = {
    vim.fn.expand("~")..'/.config',
    vim.fn.expand("~")..'/bin',
    vim.fn.expand("~")..'/notes'
}
vim.keymap.set('n', '<leader>pp', function()
    local fzf = require("fzf-lua")
    local choice = fzf.fzf_exec(project_list)
    fzf.files({ cwd = choice })
end)

Hi @elenapan, what an honor for you to be interested in my project, to this day I still use a color scheme for my terminal from one of your customizations :)

As for your question, fzf-lua is async and runs in a lua coroutine so you can’t chain the commands the way you tried, you need to create a custom action, see:
https://github.com/ibhagwan/fzf-lua/wiki/Advanced#fzf-exec-acts

fzf.fzf_exec(project_list, {
  actions = {
    ['default'] = {
      fn = function(sel, opts)
        fzf.files({ cwd = sel[1] })
      end,
      -- we use `noclose` to reuse the existing floating windows
      -- it will work regardless but you’ll see the windows “flash”
      noclose = 1,
    },
    -- anything is possible with some effort and lua
    ['ctrl-y'] = function(selected, opts)
      print("selected item:", selected[1])
    end
  }
})

I personally use something similar in my config which switches the cwd and also lets me go back to the previous active one:

Thank you for pointing me to the right direction. Your snippet worked perfectly.

Also, to return the kind words, you have done an amazing job, fzf-lua is the one plugin I cannot live without :)

hey, im trying to use your function to set the cwd with a picker, i do see the picker but its empty, im using yout exact code from https://github.com/ibhagwan/nvim-lua/blob/d6a3dd1de64414b48231d6498b901f8c5a8bc9d3/lua/plugins/fzf-lua/cmds.lua#L66-L109

any idea?

I don’t know, you’d have to debug it, use old school peint debugging to see if the callback is called and with what values.
