Module CudfAdd

module CudfAdd: sig .. end

Library of additional functions for the CUDF format.

Basic comparison operations for packages

val equal : Cudf.package -> Cudf.package -> bool

Equality test: two CUDF packages are equal if their names and versions are equal.

val compare : Cudf.package -> Cudf.package -> int

Compare function: compares two CUDF packages using standard CUDF comparison operator (i.e. comparing by their name and version).

Specialized data structures for CUDF packages

val hash : Cudf.package -> int

A hash function for CUDF packages, using only their name and version.

Data structures:

module Cudf_hashtbl: Hashtbl.S  with type key = Cudf.package

Specialized hashtable for CUDF packages.

module Cudf_set: Set.S  with type elt = Cudf.package

Specialized set data structure for CUDF packages.

val to_set : Cudf_set.elt list -> Cudf_set.t

Convert a list of CUDF packages to a set of CUDF packages.

Functions to encode and decode strings.

val encode : string -> string

Encode a string.

Replaces all the "not allowed" characters with their ASCII code (in hexadecimal format), prefixed with a '%' sign.

Only "allowed" characters are letters, numbers and these: @/+().-, all the others are replaced.

Examples:

encode "ab" = "ab"
encode "|" = "%7c"
encode "a|b" = "a%7cb"

val decode : string -> string

Decode a string. Opposite of the encode function.

Replaces all the encoded "not allowed" characters in the string by their original (i.e. not encoded) versions.

Examples:

decode "ab" = "ab"
decode "%7c" = "|"
decode "a%7cb" = "a|b"

Formatting, printing, converting to string.

val string_of : (Format.formatter -> 'a -> 'b) -> 'a -> string

val pp_version : Format.formatter -> Cudf.package -> unit

val pp_package : Format.formatter -> Cudf.package -> unit

val string_of_version : Cudf.package -> string

val string_of_package : Cudf.package -> string

module StringSet: Set.S  with type elt = ExtLib.String.t

val pkgnames : Cudf.universe -> StringSet.t

Additional functions on the CUDF data types.

val latest : Cudf.package list -> Cudf.package list

Returns a list of packages containing for each package only the latest version

val add_properties : Cudf.preamble -> (string * Cudf_types.typedecl1) list -> Cudf.preamble

val is_essential : Cudf.package -> bool

val realversionmap : Cudf.package list ->
       (Cudf_types.pkgname * string, Cudf.package) ExtLib.Hashtbl.t

build a hash table that associates (package name, String version) to CUDF packages

val vartoint : Cudf.universe -> Cudf.package -> int

val inttovar : Cudf.universe -> int -> Cudf.package

val add_to_package_list : ('a, 'b list Pervasives.ref) ExtLib.Hashtbl.t -> 'a -> 'b -> unit

val get_package_list : ('a, 'b list Pervasives.ref) ExtLib.Hashtbl.t -> 'a -> 'b list

val unique : 'a list -> 'a list

val normalize_set : int list -> int list

val who_provides : Cudf.universe -> Cudf_types.pkgname * Cudf_types.constr -> Cudf.package list

val resolve_vpkg_int : Cudf.universe -> Cudf_types.pkgname * Cudf_types.constr -> int list

val resolve_vpkgs_int : Cudf.universe -> (Cudf_types.pkgname * Cudf_types.constr) list -> int list

val resolve_deps : Cudf.universe ->
       (Cudf_types.pkgname * Cudf_types.constr) list -> Cudf.package list

val who_depends : Cudf.universe -> Cudf.package -> Cudf.package list list

val who_conflicts : (int, int list Pervasives.ref) ExtLib.Hashtbl.t ->
       Cudf.universe -> Cudf.package -> Cudf.package list

val init_conflicts : Cudf.universe -> (int, int list Pervasives.ref) ExtLib.Hashtbl.t

val compute_pool : Cudf.universe -> int list list array * int list array

val cudfop : (string * string) option ->
       ([> `Eq | `Geq | `Gt | `Leq | `Lt ] * string) option

val pp : (Cudf_types.pkgname * Cudf_types.version -> 'a * Cudf_types.pkgname) ->
       ?decode:(Cudf_types.pkgname -> string) ->
       Cudf.package -> string * string * (string * string) list

pp ?decode from_cudf pkg package pretty printer. from_cudf a function that gets a (name,cudfversion) pair and returns a (name,realversion). ?decode a function that decode the package name and version

returns : a pair (name,versiom,property list)

note that if the package has version less then 0, then the version is printed as "nan"
