Description
This PPX compiles
[%tyre {|re|}]
into 'a Tyre.t
and
function%tyre
| {|re1|} as x1 -> e1
...
| {|reN|} as x2 -> eN
into 'a Type.route
, where re
, re1
, ... are regular expressions
expressed in a slightly extended subset of PCRE. The interpretations are:
re?
extracts an option of whatre
extracts.re+
,re*
,re{n,m}
extracts a list of whatre
extracts.(?@qname)
refers to any identifier bound to a typed regular expression of type'a Tyre.t
.- One or more
(?<v>re)
at the top level can be used to bind variables instead ofas ...
. - One or more
(?<v>re)
in a sequence extracts an object where each methodv
is bound to whatre
extracts. - An alternative with one
(?<v>re)
per branch extracts a polymorphic variant where each constructor`v
receives whatre
extracts as its argument. (?&v:qname)
is a shortcut for(?<v>(?&qname))
.
