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)([😇ω])+", .{.encoding = .utf8}, "abc😇ωωωωω")) |res| {
std.debug.warn("Test: {}, 1: {}\n", .{ res.capture("test"), res.captures[1] });
