|
* Add literal pattern syntax and change tree structure syntaxRyo Nihei2021-07-229-23/+55
| | | | | | - Literal patterns don't interpret the special characters of regular expressions. In other words, 'abc|def' matches only `abc|def`, not `abc` or `def`. - Change tree structure syntax from '(...) to #(...).
