Mini pick - edit command history?

Question

In telescope there is a default keybind to edit a command from the command history list .

Below is an excerpt from the telescope docs:

builtin.command_history({opts})          *telescope.builtin.command_history()*
    Lists commands that were executed recently, and reruns them on `<cr>`
    - Default keymaps:
      - `<C-e>`: open the command line with the text of the currently selected
        result populated in it

Is there a way to emulate this behavior when using mini pick's history command?

There is no such action/mapping built-in, but it is possible to write custom picker that has one. Something like this:

require('mini.pick').setup()
require('mini.extra').setup()

MiniPick.registry.command_history = function()
  local edit_command = function()
    local cur_match = MiniPick.get_picker_matches().current
    cur_match = cur_match:gsub('^: ', ':')
    vim.schedule(function() vim.api.nvim_input(cur_match) end)
    return true
  end
  local opts = { mappings = { edit_command = { char = '<C-e>', func = edit_command } } }
  MiniExtra.pickers.history({ scope = ':' }, opts)
end

Now executing :Pick command_history will open picker with command history and custom <C-e> mapping (it is visible after pressing <S-Tab>). Pressing <C-e> stops a picker and puts command in command line to edit.

The reason it is not present by default is because it makes sense only for command and search history (while there are other history types present). But I've needed something like this myself several times, so maybe it is indeed useful to have built-in at least for those history types. I'll think about it.

@eb0687, thanks to @TheLeoP, after #1960 the <C-e> mapping is now built-in for history picker, works only for command and search history. Thanks for mentioning it!

glad to have helped in someway even if indirectly

thanks for your response, I just figured it out as well, this is my attempt:

 local history_mappings = {
            execute = {
                char = "<C-e>",
                func = function()
                    local MiniPick = require("mini.pick")
                    local match = MiniPick.get_picker_matches()
                    if not match then
                        return
                    end

                    local value = type(match.current) == "table" and match.current.value or tostring(match.current)
                    value = value:gsub("^:+", "")
                    MiniPick.stop()
                    vim.schedule(function()
                        local cmd = ":" .. value
                        local keys = vim.api.nvim_replace_termcodes(cmd, true, false, true)
                        vim.api.nvim_feedkeys(keys, "n", false)
                    end)
                end,
            },
        }
        
keymap("<leader>fch", function()
    MiniExtra.pickers.history({ scope = ":" }, { mappings = history_mappings })
end, "Find command history")

did not know about this registry thing, looks cleaner, i think il adapt mine to your style. thanks!

Nice!

did not know about this registry thing, looks cleaner ...

It is documented here.
