Trying to build syntax-highlighting results in a "broken regex" error for multiple lines. "/home/user/build/src/syntax-highlighting-5.37.0/data/syntax/rest.xml" line 27 broken regex: "^\\s*\\.\\. [\\w-_\\.]+::(\\s|$)" problem: "invalid range in character class" at offset 12 "/home/user/build/src/syntax-highlighting-5.37.0/data/syntax/rest.xml" line 31 broken regex: "^(\\s*)\\.\\.\\s(?![\\w-_\\.]+::(\\s|$))" problem: "invalid range in character class" at offset 18 "/home/user/build/src/syntax-highlighting-5.37.0/data/syntax/rest.xml" line 41 broken regex: "(^|[-\\s'\"\\(\\[{</:‘“’«¡¿‐‑‒–— ])`[^\\s].*`(?=:[\\w-_\\.\\+]+:)" problem: "invalid range in character class" at offset 47 "/home/user/build/src/syntax-highlighting-5.37.0/data/syntax/rest.xml" line 42 broken regex: ":[\\w-_\\.\\+]+:(?=`)" problem: "invalid range in character class" at offset 4 "/home/user/build/src/syntax-highlighting-5.37.0/data/syntax/rest.xml" line 59 broken regex: ":[\\w-_\\.\\+]+:" problem: "invalid range in character class" at offset 4 Commenting out those lines fixes the issue, but is obviously not preferable.
I can also confirm this problem under Gentoo, using Qt 5.9.1
Git commit ad077e4045e650e1708b6c81d33a14f4a9c99a5d by Heiko Becker. Committed on 23/08/2017 at 14:16. Pushed by heikobecker into branch 'master'. Escape hyphen in rest.xml regular expressions Summary: The unescaped hyphen caused a build failure with pcre2-10.30 due to a broken regex: 'syntax-highlighting/data/syntax/rest.xml" line 27 broken regex: "^\\s*\\.\\. [w-_\\.]+::(\\s|$)" problem: "range out of order in character class" at offset 12'. The pcre2pattern documentation says this: "Perl treats a hyphen as a literal if it appears before or after a POSIX class (see below) or before or after a character type escape such as as \d or \H. However, unless the hyphen is the last character in the class, Perl outputs a warning in its warning mode, as this is most likely a user error. As PCRE2 has no facility for warning, an error is given in these cases." Test Plan: cmake && make && make test works fine pcre2-10.30, quick look at http://docutils.sourceforge.net/FAQ.txt in kate seems fine.
