Module Core_kernel.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 : Core_kernel__.Import.string

all hg repos and their versions

val version_list : Core_kernel__.Import.string Core_kernel__.Import.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 : (Core_kernel__.Import.string * Core_kernel__.Arg.spec * Core_kernel__.Import.string) Core_kernel__.Import.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 : Core_kernel__.Import.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.
