[Request] Filter entries by given range?

[Ajaymamtora]

Could we add an option to filter the picker entries by a given range?

For example we could bind in visual selection to take the start and end lines, and pass that into telescope-undo, then filter entries if they don't have a diff between the given lines? I used this a lot in IntelliJ and it would be useful to have here. It probably doesnt have to be smart and try and resolve where code has moved about between diffs, could probably just check the diff lies between the given line numbers

Maybe something like this before passing it into telescope:

local function undo_history_for_range(startline, endline)
    local undotree = vim.fn.undotree()
    local changes = {}

    for _, entry in ipairs(undotree.entries) do
        for _, change in ipairs(entry.changes or {}) do
            if change.new_start >= startline and change.old_end <= endline then
                table.insert(changes, change)
            end
        end
    end

    return changes
end

-- Example usage: Get undo history for lines 10 to 20
local changes = undo_history_for_range(10, 20)
print(vim.inspect(changes))
