Based on line 72, I think the intent was always that
-
would be a valid character for api-xrefs IDs (even though it's not a valid character for C++ identifiers). Prior to this fix, API IDs with-
characters (e.g.,[api]#my-api#
in asciidoc) were silently not getting thehref
treatment, because they were missed by the regex on line 117. I.e.,[api]#my_api#
would get a link in the HTML,[api]#my-api#
would not, and no error was generated.This took a while to debug.
Caveat: I know nothing about Ruby.
