Tyre is a set of combinators to build type-safe regular expressions, allowing automatic extraction and modification of matched groups.
Tyre is bi-directional: a typed regular expressions can be used for parsing and unparsing. It also allows routing, by providing a list of regexs/routes and their handlers.
Tyre is pure OCaml and uses re. To install it:
opam install tyre
# let dim = Tyre.( str"dim:" *> int <&> str"x" *> int ) ;; val dim : (int * int) Tyre.t # let dim_re = Tyre.compile dim ;; val dim_re : (int * int) Tyre.re # Tyre.exec dim_re "dim:3x4" ;; - : (int * int, (int * int) Tyre.error) result = Result.Ok (3, 4) # Tyre.eval dim (2, 5) ;; - : string = "dim:2x5"
Some benchmarks are available under the benchmark/ directory. The benchmark compares the parsing of HTTP requests using angstrom and various tyre methods. You can run them with:
./benchmark/data/replicate benchmark/data/http-requests.txt 100 jbuilder exec benchmark/benchmark_angstrom.exe -- -a
