Module `Merlin_utils.Marg`Source

Argument parsing library which fold over arguments

Specifications of arguments is split in two passes:

_ table for parsing global arguments (compiler flags, merlin configuration)
a (string * _ t) for parsing command local arguments

Sourcetype 'acc t = string list -> 'acc -> string list * 'acc

Action associated to a flag updating a state of type 'acc. It takes a list of arguments and either succeeds returning untouched arguments or fails raising an exception.

Sourcetype 'acc table = (string, 'acc t) Hashtbl.t

A table mapping a flag to the corresponding action

Combinators for building actions

Sourceval unit : ('acc -> 'acc) -> 'acc t

Action updating state and not consuming any argument

Sourceval param : string -> (string -> 'acc -> 'acc) -> 'acc t

Action consuming a single argument

Sourceval bool : (bool -> 'acc -> 'acc) -> 'acc t

Action consuming a boolean argument

Sourceval unit_ignore : 'acc t

Action doing nothing

Sourceval param_ignore : 'acc t

Action doing nothing and dropping one argument

Parsing of argument lists

Sourcetype docstring = string

Sourcetype 'a spec = string * docstring * 'a t

Source

val parse_one : 
  warning:(string -> unit) ->
  'global table ->
  'local spec list ->
  string list ->
  'global ->
  'local ->
  (string list * 'global * 'local) option

Consume at most one flag from the list, returning updated state or None in case of failure. Warning function is called with an error message in case of incorrect use.
