czrex

Simple zig wrapper for the C++ regex library

Example

• Regex

  const std = @import("std");
  const regex = @import("czrex");
  
  pub fn main() !void {
      const allocator = std.heap.page_allocator;
  
      var re = try regex.Regex.compile(allocator, "a(b+)", null);
      defer re.deinit();
  
      if (try re.match("abbbb")) |match| {
          defer match.deinit();
          const groups = match.groups;
          std.debug.print("'{s}' at index: {}\n", .{ groups[0].slice, groups[0].index });
          std.debug.print("'{s}' at index: {}\n", .{ groups[1].slice, groups[1].index });
      }
  }

• Wide Regex (Unicode)

  const std = @import("std");
  const regex = @import("czrex");
  
  pub fn main() !void {
      const allocator = std.heap.page_allocator;
  
      var re = try regex.WRegex.compile(allocator, "a(🍕+)", null);
      defer re.deinit();
  
      if (try re.match("a🍕🍕🍕🍕")) |match| {
          defer match.deinit();
          const groups = match.groups;
          std.debug.print("'{s}' at index: {}\n", .{ groups[0].slice, groups[0].index });
          std.debug.print("'{s}' at index: {}\n", .{ groups[1].slice, groups[1].index });
      }
  }
