Module Version_util

This module gives access to the same version/build information returned by Command-based executables when called with the -version or -build-info flags by $0 version (-build-info | -version) or $0 (-build-info | -version).

Here's how it works: we arrange for the build system to, at link time, include an object file that defines symbols that version_util.ml uses to get the strings that contain the information that this module provides. When building with OMake, our OMakeroot runs build_info.sh to generate *.build_info.c with the symbols and that is linked in.

val version : string

all hg repos and their versions

val version_list : string list

same as version, but one string per line

module Version : sig ... end

Version may be used to parse a single entry from version_list.

val arg_spec : (string * Core_kernel.Arg.spec * string) list
module Application_specific_fields : sig ... end

Application_specific_fields is a single field in the build-info sexp that holds a Sexp.t String.Map.t, which can be chosen by the application to hold custom fields that it needs.

val build_info : string

Various additional information about the circumstances of the build: who built it, when, on what machine, etc. build_info is the information as it was generated by the build system. reprint_build_info parses and prints the string back, which alters a bit the layout and order of the fields but more importantly allows to display times in the current zone.

val build_info_as_sexp : Core_kernel.Sexp.t
val reprint_build_info : (Core_kernel.Time.t -> Core_kernel.Sexp.t) -> string
val username : string option
val hostname : string option
val kernel : string option
val build_time : Core_kernel.Time.t option
val x_library_inlining : bool
val portable_int63 : bool
val dynlinkable_code : bool
val compiled_for_speed : bool
val application_specific_fields : Application_specific_fields.t option
val ocaml_version : string
val allowed_projections : string list option
val executable_path : string
