Module `Attributes`Source

Sourcetype vernac_flag_type =

| FlagIdent of string
| FlagString of string

The type of parsing attribute data

Sourcetype vernac_flags = vernac_flag list

Sourceand vernac_flag = string * vernac_flag_value

Sourceand vernac_flag_value =

| VernacFlagEmpty
| VernacFlagLeaf of vernac_flag_type
| VernacFlagList of vernac_flags

Sourceval pr_vernac_flag : vernac_flag -> Pp.t

Sourcetype +'a attribute

The type of attributes. When parsing attributes if an 'a attribute is present then an 'a value will be produced. In the most general case, an attribute transforms the raw flags along with its value.

Sourceval parse : 'a attribute -> vernac_flags -> 'a

Errors on unsupported attributes.

Sourceval unsupported_attributes : vernac_flags -> unit

Errors if the list of flags is nonempty.

Sourcemodule Notations : sig ... end

Notations to combine attributes.

Definitions for some standard attributes.

Sourceval polymorphic : bool attribute

Sourceval program : bool attribute

Sourceval template : bool option attribute

Sourceval locality : bool option attribute

Sourceval option_locality : Goptions.option_locality attribute

Sourceval deprecation : Deprecation.t option attribute

Sourceval canonical_field : bool attribute

Sourceval canonical_instance : bool attribute

Sourceval using : string option attribute

Sourceval typing_flags : Declarations.typing_flags option attribute

Enable/Disable universe checking

Sourceval program_mode_option_name : string list

For internal use when messing with the global option.

Sourceval only_locality : vernac_flags -> bool option

Parse attributes allowing only locality.

Sourceval only_polymorphism : vernac_flags -> bool

Parse attributes allowing only polymorphism. Uses the global flag for the default value.

Sourceval parse_drop_extra : 'a attribute -> vernac_flags -> 'a

Ignores unsupported attributes.

Sourceval parse_with_extra : 'a attribute -> vernac_flags -> vernac_flags * 'a

Returns unsupported attributes.

* Defining attributes.

Sourcetype 'a key_parser = 'a option -> vernac_flag_value -> 'a

A parser for some key in an attribute. It is given a nonempty 'a option when the attribute is multiply set for some command.

eg in #[polymorphic] Monomorphic Definition foo := ..., when parsing Monomorphic it will be given Some true.

Sourceval attribute_of_list : (string * 'a key_parser) list -> 'a option attribute

Make an attribute from a list of key parsers together with their associated key.

Sourceval bool_attribute : name:string -> bool option attribute

Define boolean attribute name, of the form name={yes,no}. The attribute may only be set once for a command.

Source

val deprecated_bool_attribute : 
  name:string ->
  on:string ->
  off:string ->
  bool option attribute

Define boolean attribute name with will be set when on is provided and unset when off is provided. The attribute may only be set once for a command; this attribute both accepts the old on off syntax and new attribute syntax on=yes on=no

Sourceval qualify_attribute : string -> 'a attribute -> 'a attribute

qualified_attribute qual att treats #[qual(atts)] like att treats atts.

Combinators to help define your own parsers. See the implementation of bool_attribute for practical use.

Sourceval assert_empty : string -> vernac_flag_value -> unit

assert_empty key v errors if v is not empty. key is used in the error message as the name of the attribute.

Sourceval assert_once : name:string -> 'a option -> unit

assert_once ~name v errors if v is not empty. name is used in the error message as the name of the attribute. Used to ensure that a given attribute is not reapeated.

Sourceval single_key_parser : name:string -> key:string -> 'a -> 'a key_parser

single_key_parser ~name ~key v makes a parser for attribute name giving the constant value v for key key taking no arguments. name may only be given once.

Sourceval make_attribute : (vernac_flags -> vernac_flags * 'a) -> 'a attribute

Make an attribute using the internal representation, thus with access to the full power of attributes. Unstable.

Sourceval vernac_polymorphic_flag : vernac_flag

Compatibility values for parsing Polymorphic.

Sourceval vernac_monomorphic_flag : vernac_flag

Sourceval universe_polymorphism_option_name : string list

For internal use.

Sourceval is_universe_polymorphism : unit -> bool
