[Message part 3 (text/plain, inline)]

Hello Emacs, As we know, Emacs 30 introduced a PEG implementation, peg.el. I found that the following code doesn't work properly when reading the PEG documentation with folks: -------------- code from lispref/peg.texi ------------------------- (define-peg-rule digit ()   [0-9]) (define-peg-ruleset number-grammar         '((number sign digit (* digit))           digit  ;; A reference to the definition above.           (sign (or "+" "-" "")))) ------------------------------------------------------------------- We noticed that the correct usage of this macro is provided in peg.el. --------------code from peg.el ------------------------------------ ;;;; Named rulesets: ;; ;; You can define a set of rules for later use with: ;; ;;     (define-peg-ruleset myrules ;;       (sign  () (or "+" "-" "")) ;;       (digit () [0-9]) ;;       (nat   () digit (* digit)) ;;       (int   () sign digit (* digit)) ;;       (float () int "." nat)) ------------------------------------------------------------------- Perhaps we can correct the errors in the documentation through a simple replacement.  Regards, Yue Yi

> Thanks, three commits :p

And that's because I caught a first problem before the first push!
Otherwise it would have been 4 commits!  <eye-roll>
I really outdid myself.
