Documentation comments

val docstring : string ‑> Ppxlib_ast__.Import.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 ‑> Ppxlib_ast__.Import.Location.t

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 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 ‑> Ppxlib_ast__.Import.Parsetree.attribute
val add_docs_attrs : docs ‑> Ppxlib_ast__.Import.Parsetree.attributes ‑> Ppxlib_ast__.Import.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 info type represents documentation attached to a field or constructor.

type info = docstring option
val empty_info : info
val info_attr : docstring ‑> Ppxlib_ast__.Import.Parsetree.attribute
val add_info_attrs : info ‑> Ppxlib_ast__.Import.Parsetree.attributes ‑> Ppxlib_ast__.Import.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 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 ‑> Ppxlib_ast__.Import.Parsetree.attribute
val add_text_attrs : text ‑> Ppxlib_ast__.Import.Parsetree.attributes ‑> Ppxlib_ast__.Import.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
