fix: hex strings misparsed after non-string meta values - #294
Merged
Conversation
When the last value in a meta: section was an integer or boolean, the lexer stayed in the $meta state at the strings keyword. The $meta-state strings token transitioned back to @default but, unlike its @default counterpart, never set sectionStrings(true) -- so a following { was not recognized as a hex string opener and its nibbles were lexed as integers, causing a ParserError. A trailing string meta value masked the bug because the closing quote already returns the lexer to @default. Also sets sectionStrings(false) on the $meta-state condition token to mirror the @default counterpart. Adds C++ and Python regression tests. Co-Authored-By: Claude <noreply@anthropic.com>
