Hi all,
I've encountered an issue where using `perl = TRUE` for regular expressions
with grepl() causes an error on ubuntu CI runners only.
Is this a known limitation of perl = TRUE for grep and family in base R? Or
is there a suggested workaround?
The issue is specifically with lookbehinds:
PCRE pattern compilation error
'lookbehind assertion is not fixed length'
at '(?<=(FeatureServer|MapServer)/)[0-9]+/?$'
Any guidance would be very much appreciated! I'd like to avoid adding a
stringi dependency if possible.
