With versions 27.2 and later, we get: $ od -c ETAGS-test 0000000 \f \n f o o . c , 0 \n 0000012 so no match, and replacing \1 by \2 in the --regex argument (admittedly not well defined since there is a single registered group), we get: $ od -c ETAGS-test 0000000 \f \n f o o . c , 3 2 \n D E F I N 0000020 E _ F F ( T A G f u n c 177 T A 0000040 G f u n c 001 1 , 0 \n so "TAG func" between \x7f and \x01. In both cases the result is different from the one from 26.1, which I would think is the expected one. Using etags --regex='/DEFINE_FF *(\(TAG \)? *\([^)]+\)/\2/' \ --output ETAGS-test foo.c (that is, without a shy group) works as expected, in 26.1 and later.

I'm guessing this is because Emacs 27 switched to the Gnulib's regex implementation in etags and other lib-src programs, whereas previous versions used the Emacs's own regex code (which is still used for Emacs's own regex search and replacement code).

Yes that's expected, as glibc/Gnulib regex doesn't do shy groups. A workaround is to not use shy groups, e.g.: etags --regex='/DEFINE_FF *(\(TAG \)? *\([^)]+\)/\2/' \ --output ETAGS-test foo.c This should be portable between both older and newer etags.

I'm guessing this is because Emacs 27 switched to the Gnulib's regex

CC'ing Paul Eggert, in the hope he can tell whether this is expected
or not, or how to fix it.

Yes that's expected, as glibc/Gnulib regex doesn't do shy groups. A workaround is to not use shy groups, e.g.:

etags --regex='/DEFINE_FF *(\(TAG \)? *\([^)]+\)/\2/' \
  --output ETAGS-test foo.c

This should be portable between both older and newer etags.
Thanks for analyzing this.
This looks like a silent change.
Maybe etags' documentation should reflect this, as currently the man
page still says "The syntax of regexps is the same as in emacs."
which is no longer true.
