How to 'overwrite existing EE global variables'

[alycda]

Hi, is it possible to use stash to override a global variable without using an EE embed? I did the following test:

{exp:stash:set name="my_var" type="snippet"}Value{/exp:stash:set}
{my_var} | {exp:stash:get name="my_var" type="snippet"}

and found that only the second variable will return the intended result, unless I place the second line in an EE template and call with an embed:

{embed="site/_test"}

What I want to achieve is setting default variables as a global var, something like a standard page title, but when I loop through channels and set Stash variables, I want to be able to override global variables, if the stash variable is not empty. I'm putting the global variable that I want to override in a snippet (i would use a stash embed, but in this case a very simple snippet is my preferred choice, also, sometimes I want to parse PHP which stash can't handle).

found it! {exp:stash:parse process="end"}. I'm still very new to all of this so if you have any insight, about this, I'd appreciate it.

You may find the slides from this presentation I gave last year to be helpful. Particularly the example following slide 17. Basically, it all comes down to parse order: https://speakerdeck.com/croxton/stash-core-principles
