Module B0_ocaml.Conf

Toolchain configuration.

This module provides access to the OCaml toolchain configuration as output by ocaml{c,opt} -config.


type t

The type for the OCaml toolchain configuration.

val of_string : ?file:B0_std.Fpath.t -> string -> (t, string) Stdlib.result

of_string ~file data parses toolchain configuration from data as output by the compiler's -config option assuming it was read from file file (defaults to B0_std.Fpath.dash).

val write : B0_memo.t -> comp:B0_memo.Tool.t -> o:B0_std.Fpath.t -> unit

write m ~o writes the toolchain configuration to o by running comp with -config.

read m file reads a toolchain configuration from file.


val find : string -> t -> string option

find f c looks up the field f in configuration c. See ocamlc -config for the list of fields.

val version : t -> int * int * int * string option

version c is the compiler version string "major.minor[.patchlevel][+additional-info]" parsed using (major, minor, patch, additional-info). If patch-level is absent it is turned into a 0.

val where : t -> B0_std.Fpath.t

where c is the location of OCaml's library directory.

val asm_ext : t -> B0_std.Fpath.ext

asm_ext is the file extension for assembly files.

val dll_ext : t -> B0_std.Fpath.ext

dll_ext is the file extension for C dynamic libraries.

val exe_ext : t -> B0_std.Fpath.ext

ext_ext is the file extension for executable binaries.

val lib_ext : t -> B0_std.Fpath.ext

ext_lib is the file extension for C static libraries.

val obj_ext : t -> B0_std.Fpath.ext

obj_ext is the file extension for C object files.

has_dynlink determines whether the platform supports dynamic linking.


val to_string_map : t -> string B0_std.String.Map.t

to_string_map c are the fields of c as a string map.

val of_string_map : string B0_std.String.Map.t -> (t, string) Stdlib.result

of_string_map m is a configuration from string map m. m needs at least on key for each parsed field above otherwise the function errors.

Store key

val key : t B0_store.key

conf is a memo key store with the OCaml configuration.

val version' : B0_build.t -> (int * int * int * string option) B0_std.Fut.t

version' b gets Conf.version from key.
