(Re)Initialise all docstring state

val warn_bad_docstrings : unit -> unit

Emit warnings for unattached and ambiguous docstrings

=== Docstrings ===

type docstring

Documentation comments

val docstring : string -> Location.t -> docstring

Create a docstring

val register : docstring -> unit

Register a docstring

val docstring_body : docstring -> string

Get the text of a docstring

val docstring_loc : docstring -> Location.t

Get the location of a docstring

=== Set functions These functions are used by the lexer to associate docstrings to the locations of tokens. ===

val set_pre_docstrings : Lexing.position -> docstring list -> unit

Docstrings immediately preceding a token

val set_post_docstrings : Lexing.position -> docstring list -> unit

Docstrings immediately following a token

val set_floating_docstrings : Lexing.position -> docstring list -> unit

Docstrings not immediately adjacent to a token

val set_pre_extra_docstrings : Lexing.position -> docstring list -> unit

Docstrings immediately following the token which precedes this one

val set_post_extra_docstrings : Lexing.position -> docstring list -> unit

Docstrings immediately preceding the token which follows this one

=== Items The Docstrings.docs type represents documentation attached to an item. ===

type docs = {
 docs_pre :  docstring option ;
 docs_post :  docstring option ;
 }

val empty_docs : docs

val docs_attr : docstring -> Parsetree.attribute

val add_docs_attrs : docs -> Parsetree.attributes -> Parsetree.attributes

Convert item documentation to attributes and add them to an attribute list

val symbol_docs : unit -> docs

Fetch the item documentation for the current symbol. This also marks this documentation (for ambiguity warnings).

val symbol_docs_lazy : unit -> docs Lazy.t

val rhs_docs : int -> int -> docs

Fetch the item documentation for the symbols between two positions. This also marks this documentation (for ambiguity warnings).

val rhs_docs_lazy : int -> int -> docs Lazy.t

val mark_symbol_docs : unit -> unit

Mark the item documentation for the current symbol (for ambiguity warnings).

val mark_rhs_docs : int -> int -> unit

Mark as associated the item documentation for the symbols between two positions (for ambiguity warnings)

=== Fields and constructors The Docstrings.info type represents documentation attached to a field or constructor. ===

type info = docstring option

val empty_info : info

val info_attr : docstring -> Parsetree.attribute

val add_info_attrs : info -> Parsetree.attributes -> Parsetree.attributes

Convert field info to attributes and add them to an attribute list

val symbol_info : unit -> info

Fetch the field info for the current symbol.

val rhs_info : int -> info

Fetch the field info following the symbol at a given position.

=== Unattached comments The Docstrings.text type represents documentation which is not attached to anything. ===

type text = docstring list

val empty_text : text

val empty_text_lazy : text Lazy.t

val text_attr : docstring -> Parsetree.attribute

val add_text_attrs : text -> Parsetree.attributes -> Parsetree.attributes

Convert text to attributes and add them to an attribute list

val symbol_text : unit -> text

Fetch the text preceding the current symbol.

val symbol_text_lazy : unit -> text Lazy.t

val rhs_text : int -> text

Fetch the text preceding the symbol at the given position.

val rhs_text_lazy : int -> text Lazy.t

=== Extra text There may be additional text attached to the delimiters of a block (e.g. struct and end). This is fetched by the following functions, which are applied to the contents of the block rather than the delimiters. ===

val symbol_pre_extra_text : unit -> text

Fetch additional text preceding the current symbol

val symbol_post_extra_text : unit -> text

Fetch additional text following the current symbol

val rhs_pre_extra_text : int -> text

Fetch additional text preceding the symbol at the given position

val rhs_post_extra_text : int -> text

Fetch additional text following the symbol at the given position
