inline std::string NormalizeRegexPattern(const std::string &rssPattern)#
Normalizes a regex path pattern string.
This function processes a path string to resolve current (‘.’) and parent (‘..’) directory indicators according to standard path canonicalization rules, plus custom rules for regex generation.
Rules applied:
Path segments of ‘.’ are removed (e.g., “a/./b” -> “a/b”).
A directory followed by ‘..’ is resolved (e.g., “a/b/../c” -> “a/c”). Special case if the parent is any directory “.*../” and “.*\/../”. Both will result in any directory “.*\/”.
If a path attempts to navigate above the root (e.g., “../a” or “a/../../b”), this only works if the following directory is any directory (starts with “.*”).
- Parameters:
rssPattern – [in] Reference to the regex pattern string to normalize.
- Returns:
The normalized regex pattern string.
