Real-time list of all global variables and values?

[Hippo Man]

Is there a way I can get a real-time list of all of Tasker's global variables and their current values?

I know I can see this info for _my_ global variables in the VARS tab, but I'm talking about programmatically getting a list of all global variables, both mine and Tasker's, and their current values. I'd like to be able to display this list in some sort of scene or app.

A key feature is that I don't want to have to know the names of all these variables in advance. I just want the list of all of them, whatever they might be named.

As an enhancement, I'd like to apply a filter to this list to only obtain the info about global variables whose names match some sort of regex, as well as optionally filtering by my variables versus Tasker's variables.

If I could get the complete list with an indication of whether any given variable is Tasker's or mine, I could write the filtering logic, myself.

Any ideas about how I could get that complete list?

Thank you in advance.

Hi, you can get your own variables with Action-Tasker-TestTasker, Type: Global Variables. I do not think, that you can get a list of the build in variables.

Oh. OK. Thank you.

I guess maybe I will try to write a plugin to get the Tasker variables.

There's a complete list of the builtin global variable names in the Variables section of the userguide.

I know. But I'm talking about programmatically getting that list from within Tasker, in real time.

The 'real' programmatic list will be identical to the web page list until variables are added/removed.
You can't get the list programatically in any case, so it's the only option.

Pent, the OP was after the vars AND THEIR CURRENT VALUES ...

[Juergen Gruen]

Getting the values is no problem if you have the names...

Yep, and I see now (thank you, Pent) that there is no way to programmatically get the names of the Tasker globals.

... at least not from within Tasker contexts, tasks, or actions.

But what about from within a plugin? I've always wanted to write one.

i use two options, the first it's more static but i use it when i want so see haw the variables are writen, i send them to a file (txt) each time that i need. The second it's more dinamic but you must limit the number of variables so you can see them on your screen, for this i use zooper

Wow! That's a lot more work than necessary on your part. Thank you for your effort!

I had mostly given up on wanting to get this variable info in real-time out of Tasker, itself, and I was thinking about web-scraping, in order to obtain it. You saved me a lot of time.

You're welcome.

Hopefully Pent doesn't change the HTML structure of the website tomorrow ;-)
