Module OASISVersion

module OASISVersion: sig .. end

Version comparisons

This module handles versions and version comparators. A version is a string of the form "1.0.0". We compare integer and non-integer parts between to version to order them. Version comparators defined relations to a set of version. E.g. ">= 1.0.0" is a version comparator and defines all version above "1.0.0", including "1.0.0".

The version comparison is done using Debian policy for version.

Version

type t 
val version_compare : t -> t -> int

Compare versions.

val version_of_string : string -> t

Convert a string to version.

val string_of_version : t -> string

Convert a version to string.

val value : t OASISValues.t

Version number value. Not exported.

val odn_of_t : t -> OASISDataNotation.t

Dump OASISDataNotation.t. Not exported.

val chop : t -> t

Remove the last part of a version, after the last '.'. I.e. 0.2.0~alpha1 -> 0.2.

Version comparator

type comparator =
| VGreater of t
| VGreaterEqual of t
| VEqual of t
| VLesser of t
| VLesserEqual of t
| VOr of comparator * comparator
| VAnd of comparator * comparator 
val comparator_apply : t -> comparator -> bool

Apply version comparator expression.

val string_of_comparator : comparator -> string

Convert a comparator to string. Example of output ">= 3.12.1".

val varname_of_comparator : comparator -> string

Convert a comparator to variable name.

val comparator_of_string : string -> comparator

Convert a string to comparator. Not exported.

val comparator_reduce : comparator -> comparator

Simplify comparator, if possible. Not exported.

val comparator_value : comparator OASISValues.t

Check that we have a version constraint. Not exported.

val odn_of_comparator : comparator -> OASISDataNotation.t

Dump OASISDataNotation.t. Not exported.

module StringVersion: sig .. end

The module OASISVersion.StringVersion uses string for version.
