( require mzlib/pregexp)

The mzlib/pregexp library provides wrappers around regexp-match, etc. that coerce string and byte-string arguments to pregexp matchers instead of regexp matchers.

The library also re-exports: pregexp, and it re-exports regexp-quote as pregexp-quote.

( pregexp-match |  | pattern |
|  | input |
| [ | start-pos |
|  | end-pos |
|  | output-port]) |

→

(or/c (listof (or/c ( cons (or/c string? bytes?)
(or/c string? bytes?))
false/c))
false/c)

pattern : (or/c string? bytes? regexp? byte-regexp?)
input : (or/c string? bytes? input-port?)
start-pos : exact-nonnegative-integer? = 0
end-pos : (or/c exact-nonnegative-integer? false/c) = #f
output-port : (or/c output-port? false/c) = #f

( pregexp-match-positions |  | pattern |
|  | input |
| [ | start-pos |
|  | end-pos |
|  | output-port]) |

→

(or/c (listof (or/c ( cons exact-nonnegative-integer?
exact-nonnegative-integer?)
false/c))
false/c)

pattern : (or/c string? bytes? regexp? byte-regexp?)
input : (or/c string? bytes? input-port?)
start-pos : exact-nonnegative-integer? = 0
end-pos : (or/c exact-nonnegative-integer? false/c) = #f
output-port : (or/c output-port? false/c) = #f

( pregexp-split |  | pattern |  |  |  |
|  | input |  |  |  |
| [ | start-pos |  |  |  |
|  | end-pos]) |  | → |  | (listof (or/c string? bytes?))

pattern : (or/c string? bytes? regexp? byte-regexp?)
input : (or/c string? bytes? input-port?)
start-pos : exact-nonnegative-integer? = 0
end-pos : (or/c exact-nonnegative-integer? false/c) = #f

( pregexp-replace pattern input insert) → (or/c string? bytes?)
pattern : (or/c string? bytes? regexp? byte-regexp?)
input : (or/c string? bytes?)

insert

:

(or/c string? bytes?
( string? . -> . string?)
( bytes? . -> . bytes?))

( pregexp-replace* pattern input insert) → (or/c string? bytes?)
pattern : (or/c string? bytes? regexp? byte-regexp?)
input : (or/c string? bytes?)

insert

:

(or/c string? bytes?
( string? . -> . string?)
( bytes? . -> . bytes?))

Like regexp-match, etc., but a string pattern argument is compiled via pregexp, and a byte string pattern argument is compiled via byte-pregexp.
