  1. RegEx Details and Explanation



@peternlewis, my macro assumes that all macro errors are logged using the same format. I use this RegEx to parse the log entry:

^([\d-: ]+) (.+)Macro\s‘([^’]+)’ ([\w ]+)\(while executing (.+)\)

Could you please confirm that all macro errors use this format, or, if not, provide the other formats?

If you have any suggestions on how to improve this, I'd love to hear/see them. :smile:


###Example Log Entry

I don’t know. Log messages are plain text and could contain anything. There are around 800 places where log messages are printed. Most of them are debugging that is disabled by default. I’ve got no idea what other ones might be of interest I’m afraid, it isn’t something I can support. If it works and finds what you’re after now, that is as good a guarantee as you’re going to get.

Sorry for the bug guys. Hopefully this will fix it.
Please update to this new version.

Thanx for this handy and nifty macro, but the download link still gives version 1.1 instead of version 2.0?

I’m not sure why that happen for you. I just tested it (downloaded it), and it is

~~~ ReleaseNotes for VER: 2.0 2018-03-21 ~~~

BTW, I believe the macro name even change a bit with Ver 2.
Please try again and let us know what happens.

I tried again and it’s working fine. Must have been a user error from this side :wink:
Thanx again for this, I’m positive i’ll be using it a lot.

Thank you!
