[Question] How to refresh the data without closing current fzf-lua screen?

[deathmaz]

Hi, thank you very much for a very useful plugin. I'm trying to make a custom command that would work with https://github.com/ahmedkhalf/project.nvim. What i did currently is this:

  vim.keymap.set('n', '\\p',
    function()
      local history = require("project_nvim.utils.history")
      local results = history.get_recent_projects()

      fzf_lua.fzf_exec(results, {
        actions = {
          ['default'] = {
            function(selected)
              fzf_lua.files({ cwd = selected[1] })
            end,
          },
          ['ctrl-d'] = {
            function(selected)
              history.delete_project({ value = selected[1] })
            end,
            fzf_lua.actions.resume -- How to rerun everything with refreshed results?
          }
        }
      })
    end,
    opts)

I don't understand how to rerun the whole thing without closing the current fzf-lua window with refreshed results. The use case is when i press ctrl-d to delete the entry from the history file. This is done via history.delete_project function. After the entry was deleted i would like to still see the fzf-lua screen but with refreshed list, which comes from history.get_recent_projects() function. Right now i do fzf_lua.actions.resume to keep the lua screen opened, but i don't know how to refresh the data inside the list. Could you please help? Thank you very much in advance.

Right now your results is a static variable, it gets retrieved only once, when you resume the old history list is still used, it never gets refreshed.

What you want to do is use contents to a function, that way resume will call the function and refresh the list, something like:

  vim.keymap.set('n', '\\p',
    function()
      fzf_lua.fzf_exec(function(cb)
        local history = require("project_nvim.utils.history")
        local results = history.get_recent_projects()
        for _, e in ipairs(results) do
          cb(e)
        end
        cb()
      end,
      {
        actions = {
          ['default'] = {
            function(selected)
              fzf_lua.files({ cwd = selected[1] })
            end,
          },
          ['ctrl-d'] = {
            function(selected)
              history.delete_project({ value = selected[1] })
            end,
            fzf_lua.actions.resume -- How to rerun everything with refreshed results?
          }
        }
      })
    end,
    opts)

It worked, just had to move local history = require("project_nvim.utils.history") out of the scope of zf_lua.fzf_exec(function(cb)

vim.keymap.set('n', '\\p',
    function()
      local history = require("project_nvim.utils.history")
      fzf_lua.fzf_exec(function(cb)
        local results = history.get_recent_projects()
        for _, e in ipairs(results) do
          cb(e)
        end
        cb()
      end,
        {
          actions = {
            ['default'] = {
              function(selected)
                fzf_lua.files({ cwd = selected[1] })
              end,
            },
            ['ctrl-d'] = {
              function(selected)
                history.delete_project({ value = selected[1] })
              end,
              fzf_lua.actions.resume
            }
          }
        })
    end,
    opts)

Thank you very much for the help and nice plugin!

@ibhagwan How to use fzf_lua.fzf_exec inside setup.buffers.actions? Or this is not recommended?

No problem, you can call whatever you want from the actions, it will override the existing fzf-lua interface, just make sure to wrap the function inside a table to prevent the “flash” as it tells fzf-lua to reuse the interface rather than close and reopen.

I am trying to bind ['ctrl-m'] = { function() end } in files actions, but when i presss 'ctrl-m', the fzf-window shows process exit 0. (window is not closed).

i am trying to integrate flash.nvim.

Remove the {} wrapping to tell fzf-lua to close, just do ['ctrl-m'] = function() end
