open MParser First, we define a parsing combinator expr, which handles expression parsing, taking care of the operator precedence issues: let infix p op = Infix (p |>> (fun _ a b -> (`Binop (op, a, b))), Assoc_left) let operators = [ [ infix (char '*') `Mul; infix (char...
How to make the documentation of a package available on ocaml.org Unicode-aware parser combinators Profiling with landmarks Is reference semantics essentially value semantics? Replacing part of a running ocaml program using the Dynlink library Good practice for interaction between mly and mll files ...
Parser Combinator: CCParseThe module CCParse defines basic parser combinators on strings. Adapting angstrom's tutorial example gives the following snippet. Note that backtracking is explicit in CCParse, hence the use of try_ to allow it in some places. Explicit memoization with memo and fix_...
最近觉得自己的玩具语言实现一直用的ad-hoc的手写pretty printer/parser combinator毕竟是太过于落后于时代了,就去研究了一下OCaml的Format库提供的pretty… 阅读全文 大多数编程语言中为什么使用“=”与“==”,而不是“:=”与“=”,或者混用? 一千年以后 ...
Command-Line Parsing – construct basic and grouped command-line interfaces, build simple equivalents to the cryptographic md5 and shasum utilities, and shows how functional combinators can be used to declare complex command-line interfaces in a type-safe and elegant way. ...
which are combinators to manipulate a polymorphic data structure. The following shows the type of a slot specifier which modifies slotnof a slot sequence: The type says that it replaces the type of slotnin the slot sequence with and the resulting sequence type becomes to ...
