struggling to re-generate sub-menu dynamically about cli-menu

[AydinHassan]

Hello, unfortunately that is not currently possible. You would have to customise a lot of the components to make that work.

I'd probably start with creating a new menu item and customise the select action:

cli-menu/src/MenuItem/MenuMenuItem.php

Line 79 in 7ba829f

public function getSelectAction() : ?callable

This is what is triggered when you "select" the item. Note that you will need to manually construct the CliMenu instance. You might also need to replicate some of the code in this method too:

cli-menu/src/Builder/CliMenuBuilder.php

Line 207 in 92dd003

public function addSubMenu(string $text, \Closure $callback) : self

Thank you for the help! Sounds a bit daunting but at least you think it is possible? It would be a nice addition to cli-menu IMO. I may give it a crack

@AydinHassan Could you perhaps say a few more words though about why this isn't currently possible, and what would need to change (what I would need to add) in order to make it possible?

Is it not possible only because I am dealing with a sub-menu?

[AydinHassan]

@vesper8 each menu type (https://github.com/php-school/cli-menu/tree/master/src/MenuItem) has a method getSelectAction - in the case of normal selectable items, you provide the callable to be executed. In the case of submenu's the action is not customisable - it is closure which opens the menu, see my first link in the previous comment.

We could allow to specify a custom callback for when a submenu is selected but we would need to flesh out the order in which this should happen, should the user function be executed before or after the sub menu is opened? Should the user function just be passed the default action and they can just run that as and when they want?

Overall I'm not entirely sure we need this as a feature, I'd like to see an implementation before I decide if the complexity is worth it. I appreciate it might not be worth your effort in that case, so that's your call 😃

Ok thanks for the clarification @AydinHassan

Before I decide whether I want to give this a shot, can you see an alternative way of achieving what I want to do with another type of menu item?

For me it really doesn't have to be a sub-menu.. The desired outcome is that upon clicking a menu item, I am given a list of freshly-generated options, and upon clicking any of those options, an action is immediately executed.

Is there a way to achieve this right now?

@vesper8 no there is no other way
