How to search and replace with regex?

[Noel Yap]

I'm trying to turn `one=1,two=2` to `${one}=:=1,${two}=:=2`. That would normally be done in two steps. Using `perl` notation:

s/(\b\w+\b)/${\1}/g

s/=/=:=/g

I haven't been able to figure out how to get back references (ie `\1`) in Tasker nor have I found a way to use AutoTools to perform search and replace. Any help would be appreciated.

Thanks,

Noel

This should work. Make sure that there are no spaces in the search string. See attached screenshot. 

        Test

        

    A1: Variable Set 

        Name: %string 

        To: ${one}=:=1,${two}=:=2 

        Recurse Variables: Off 

        Do Maths: Off 

        Append: Off 

        

    A2: Variable Search Replace 

        Variable: %string 

        Search: \$\{([^}]+)\}=:=(\d+) 

        Ignore Case: Off 

        Multi-Line: Off 

        One Match Only: Off 

        Replace Matches: On 

        Replace With: $1=$2 

        

    A3: Flash 

        Text: %string 

        Long: On

Oops, I got that backward didn't I? Try this instead, see attached. 

        Test

        Name: %string 

        To: one=1,two=2 

        Recurse Variables: Off 

        Do Maths: Off 

        Append: Off 

        

    A2: Variable Search Replace 

        Variable: %string 

        Search: (?<=^|,)([^=]+)=(\d+) 

        Ignore Case: Off 

        Multi-Line: Off 

        One Match Only: Off 

        Replace Matches: On 

        Replace With: \${$1}=:=$2

Ah, right, `$1`, not `\1`. Thanks.
