how to use regex to generate with many style parameter

[xRowe]

Hello again

There is a elf file, the calibration or measurement parameter using different name style.

I am trying to using regex to generate a2l from elf. But .?_Cal is working but (.?_Cal |.*?_Write) will not work correctly.

How can I will regex to match many styles?

Many Thanks

Hello,

1) You could simply use the parameter --measurement-regex several times on the command line instead of joining the patterns with "|". Each pattern from the command line is checked separately, and a variable is inserted if any of them matches. 2) Your patterns are not ideal, they could be simplified by deleting ".?" and ".*?". The regex engine will report a match if any substring matches your input regex. For example, "_Cal" matches "My_Cal_Variable" 3) You should still be able to use "|" in your patterns, this is a supported feature. I would suggest using extra () around the groups, and you could also test your patterns in advance using one of the regex testing websites

Thanks for you quick action. Sorry for the late reply.

I tried 1). It works.

But when I tried 3), It does not work, Below are the error I got.

D:\Users\n95\Desktop\a2ltool-1.6.0>a2ltool --create --elffile Test_APP.elf --characteristic-regex _Cal|_Write  --output output.a2l

operable program or batch file.

--output was unexpected at this time.

D:\Users\n95\Desktop\a2ltool-1.6.0>a2ltool --create --elffile Test_APP.elf --characteristic-regex _Cal ((_Cal)|(_Write))  --output output.a2l
) was unexpected at this time.

Thank you in advance for your great help Rowe

Your problem is actually really simple: You didn't put "" around your regex, so the | symbol is interpreted by your shell as a pipe symbol.

This should work:

a2ltool --create --elffile Test_APP.elf --characteristic-regex "_Cal|_Write"  --output output.a2l
