Since August 31 it is possible to compose string variables, which is great. However, I miss more options:
1) Compose other variable types, mainly
2) manipulate them with WDL (https://msdn.microsoft.com/en-us/library/azure/mt643789.aspx), as it is currently supported when editing Conditions in advanced mode
This way lots of use cases that require counters, string manipulation etc could be implemented directly with Microsoft Flow
You can use any of the 70+ expressions from the Workflow Definition Language in Flow: https://flow.microsoft.com/blog/use-expressions-in-actions/
WDL in "Compose" actually is working: https://powerusers.microsoft.com/t5/Flow-Forum/Math-function-to-sum-or-multiply-values/m-p/8691.
But still did not found how to update existing Compose as "var++" or change it
also date/time variables please!
Please! This is so much more essential for a business workflow tool than things like connecting to Twitter!!!
I just found new actions: "Initialize variable", "set variable" and "increment variable". When initializing a variable, the following fields must be filled: name, type (boolean, integer, floating, string, object, matrix) and optionally value. I guess "Increment variable" is only valid for integers and floats, according to https://flow.microsoft.com/es-es/blog/error-handling/ .
I think it is a great step, however, I still cannot assign WDL expressions to variables, so I am forced to keep on using Compose action blocks everywhere (please see https://powerusers.microsoft.com/t5/Using-Flows/Error-when-initializing-an-integer-variable-with-an-... )
Thank you in advance!
Awesome news from @Stephen!
However, I don't see the "Expression" Tab yet in my Flows, is it still rolling out?
"Expression" Tab is announced in Action Blocks, I guess this means it will also be available in Variables, right?
@anhthuch4ngIMO this Idea shall be marked as completed since Variables acton blocks are available
