Generating fast code since 2020
- Comptime regular expression compilation
- Comptime and runtime matching
- UTF8, UTF16le, ASCII, codepoint array support
- Captures (with named
(:<name>...)support) |,*,+,?,(:?...),[...],[^...],{N},{min,},{min,max}- '\d', '\s' character classes
- Faster generated code using DFAs when possible
- search, findAll, etc.
- More character classes
- More features (backreferences etc.)
test "runtime matching" { @setEvalBranchQuota(1250); // The encoding is utf8 by default, you can use .ascii, .utf16le, .codepoint here instead. if (try match("(?<test>def|abc)([πΟ])+", .{.encoding = .utf8}, "abcπΟΟΟΟΟ")) |res| { std.debug.warn("Test: {}, 1: {}\n", .{ res.capture("test"), res.captures[1] }); } } test "comptime matching" { @setEvalBranchQuota(2700); if (comptime try match("(?<test>def|abc)([πΟ])+", .{}, "abcπΟΟΟΟΟ")) |res| { @compileError("Test: " ++ res.capture("test").? ++ ", 1: " ++ res.captures[1].?); } }
