Module Ppx_core

Ppx_core is our stdlib for the ppx code so we just include Base here

include Base

This module is the toplevel of the Base library, it is what you get when you do open Base.

The recommended way to use Base is to build with -open Base. Files compiled this way will have the environment described in this file as initial environment.

Sexp

Exporting the ad-hoc types that are recognized by ppx_sexp_* converters. sexp_array, sexp_list, and sexp_option allow a record field to be absent when converting from a sexp, and if absent, the field will take a default value of the appropriate type:

        sexp_array   [||]
        sexp_bool    false
        sexp_list    []
        sexp_option  None

sexp_opaque causes the conversion to sexp to produce the atom <opaque>.

For more documentation, see sexplib/README.md.

type 'a sexp_list = 'a list
type 'a sexp_opaque = 'a

val (~-.) : Base.Float.t ‑> Base.Float.t
external (|>) : 'a ‑> ('a ‑> 'b) ‑> 'b = "%revapply"

Reverse application operator. x |> g |> f is equivalent to f (g (x)).

external (@@) : ('a ‑> 'b) ‑> 'a ‑> 'b = "%apply"

Application operator. g @@ f @@ x is equivalent to g (f (x)).

Misc

external force : 'a Lazy.t ‑> 'a = "%lazy_force"
module Continue_or_stop = Base.Container_intf.Export.Continue_or_stop

Continue_or_stop.t is used by the f argument to fold_until in order to indicate whether folding should continue, or stop early.

module Finished_or_stopped_early = Base.Container_intf.Export.Finished_or_stopped_early

Finished_or_stopped_early.t is returned by fold_until to indicate whether f requested the fold stop, or if the fold completed.

module Not_exposed_properly = Base.Not_exposed_properly

val gen_symbol : ?⁠prefix:Ppx_core__.Import.string ‑> Ppx_core__.Import.unit ‑> Ppx_core__.Import.string

gen_symbol ?prefix () generates a fresh variable name with prefix.

  • Parameter prefix: default = "_x"
val assert_no_attributes_in : Ast_traverse.iter
val get_type_param_name : (Ppx_core__.Import.core_type * Ppx_core__.Import.variance) ‑> Ppx_core__.Import.string Loc.t

get_tparam_id tp

  • Returns the string identifier associated with tp if it is a type parameter.
class type_is_recursive : Ppx_core__.Import.rec_flag ‑> Ppx_core__.Import.type_declaration Ppx_core__.Import.list ‑> object ... end

(new type_is_recursive rec_flag tds)#go () returns whether rec_flag, tds is really a recursive type. We disregard recursive occurrences appearing in arrow types. You can override the search for certain type expressions by inheriting from this class.

val really_recursive : Ppx_core__.Import.rec_flag ‑> Ppx_core__.Import.type_declaration Ppx_core__.Import.list ‑> Ppx_core__.Import.rec_flag

really_recursive rec_flag tds = (new type_is_recursive rec_flag tds)#go ()

val loc_of_attribute : Ppx_core__.Import.attribute ‑> Location.t
val curry_applications : Ppx_core__.Import.expression ‑> Ppx_core__.Import.expression

convert multi-arg function applications into a cascade of 1-arg applications

val attribute_of_warning : Location.t ‑> Ppx_core__.Import.string ‑> Ppx_core__.Import.attribute

Encode a warning message into an 'ocaml.ppwarning' attribute which can be inserted in a generated Parsetree. The compiler will be responsible for reporting the warning.

We don't include these in Std as these are likely to break external code

module Location : sig ... end

Overrides the Location module of OCaml

module Longident : sig ... end

Overrides the Longident module of OCaml
