Regular Expressions

[Alan_37]

Hello

I was wandering if it is possible to have a function to use regular expressions in Flowcode
to be able to search in a string variable or text and output a string according to the regular expression .

Example : Outputstring = "REGEX" (Inputstring)

Hi,
The main issue with that would be the code size required on the target device.
But I'll add your suggestion to our request list.
Thanks,
Leigh

hi LeighM

Well it's true that the Regex function will take a considerable amount of target space
but trying to construct code that for example output's what's between this & that
will still take space from target + more time , with regex is simply done by using (?<=this).*?(?=that)
in only one line of code .

I understand that it mite not be a good idea to use this function on targets with less than 4k of flash but, for the rest especially devices like STM32 should not be a problem .

In my opinion this function will make Flowcode much more powerful and attractive .

Hi

Maybe a more simple solution to this is a component since Regex library's
can be found all over the place

Here is one for Arduino : https://forum.arduino.cc/index.php?topic=59917.0
