Use Variable in Regex (interpolate)

[Julia User]

How to use a julia variable in a regex string (interpolate).

var = " "
reg =  r"^$(var)+"   # Something like this
result = matchall(reg, mystring)

Is there a way to make this work?

Thanks

How about the following? I don't know if there's a shorter way.


var = " "
reg_string =  "^$(var)+"   # standard Julia string

reg = Regex(reg_string)  # make a regular expression out of the string
result = matchall(reg, mystring)



Best,

David.

 

Thanks

Great one, thanks! 

Re shorter way, it can be written as a one-liner: 

result = matchall(Regex("^$(var)+"), mystring)
