2024-02-02Fix incorrect backslash escaping of `\\`Thomas Lange1-2/+2
The regular expression part `\\` must be written as `\\\\`, not `\\\` in a PHP string variable. Although both variants (`\\\\` and `\\\`) will be passed as `\` to the regex engine in this specific case, it's correct to use 4 backslashes, as the PHP manual tells you: https://www.php.net/manual/en/regexp.reference.escape.php
2024-02-02Rewrite and optimize FunctionParser classThomas Lange1-15/+54
* Rewrite regular expressions and make them easier to read. * Use named capture groups for backreferences and array keys. * Allow backslash-escaping of quotes inside string arguments. * Allow string arguments to be enclosed between single quotes.
2021-07-20Implement new *content functions* feature (readme)Thomas Lange1-0/+84
This commit implements a new feature called *content functions* that is similar but much more powerful than the already existing *content tags* which you may have already used (`{POST[1]}`, for example). You now can also add your own *content functions* to do some interesting things like embedding a YouTube video or other things to prevent typing repetitive lines of text or code in your entities content. Read the corresponding wiki page to learn more about this: https://github.com/Nerdmind/Blog/wiki/Content-functions
