module type Expr_Op_T = sig .. end
The module type containing the subexpression composition operators. This
module type is included in the signatures of the Op and X.Op modules.
val ($|) : Cf_lex.x -> Cf_lex.x -> Cf_lex.x
Alternating composition. Use a $| b to compose an expression that
matches either expression a or expression b.
val ($&) : Cf_lex.x -> Cf_lex.x -> Cf_lex.x
Serial composition. Use a $& b to compose an expression that matches
expression a followed by expression b.
val ( !* ) : Cf_lex.x -> Cf_lex.x
Star composition. Use !*a to compose an expression that matches zero
or any number of instances of a.
val (!+) : Cf_lex.x -> Cf_lex.x
Plus composition. Use !+a to compose an expression that matches one
or more instances of a.
val (!?) : Cf_lex.x -> Cf_lex.x
Optional composition. Use !?a to compose an expression that matches
zero or one instance of a.
val (!:) : char -> Cf_lex.x
Character literal. Use !:c to compose an expression that matches the
character c.
val (!^) : (char -> bool) -> Cf_lex.x
Character set. Use !^f to compose an expression that matches any
character for which the satisfier function f returns true.
val (!~) : char Cf_seq.t -> Cf_lex.x
Regular expression sequence. Use
!~z to parse the sequence
z
according to the grammar defined in
Cf_regex module and compose
an expression that matches input accordingly. Raises
Cf_regex.Error
if the sequence is not a regular expression.
val (!$) : string -> Cf_lex.x
Regular expression string. Use
!~s to parse the string
s according
to the grammar defined in
Cf_regex module and compose an expression
that matches input accordingly. Raises
Cf_regex.Error if the string
is not a regular expression.
