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.
val sort : Cudf.package list -> Cudf.package list
Sort function: sorts a CUDF packages list using the standard CUDF comparison operator in ascending order

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.

Extended function on Cudf data types 


val who_provides : Cudf.universe -> Cudf_types.vpkg -> Cudf.package list
Return the list of packages that that respect the given constraint
val resolve_deps : Cudf.universe -> Cudf_types.vpkglist -> Cudf.package list
Return the list of packages satisfying the vpkg list
val who_depends : Cudf.universe -> Cudf.package -> Cudf.package list list
Returns the list of packages that are dependencies of the given package
type ctable = (int, int list Pervasives.ref) ExtLib.Hashtbl.t
A table to associate to each id the list of packages id that are in conflict with it. Reflexive conflicts are made explicit.
val init_conflicts : Cudf.universe -> ctable
Create a ctable from a package universe
val who_conflicts : ctable -> Cudf.universe -> Cudf.package -> Cudf.package list
Return the list of packages in conflict with the given package
val resolve_vpkg_int : Cudf.universe -> Cudf_types.vpkg -> int list
Like who_provides but returns a list of cudf ids
val resolve_vpkgs_int : Cudf.universe -> Cudf_types.vpkglist -> int list
Like resolve_deps but returns a list of cudf ids

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: 


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:



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
module StringSet: Set.S  with type elt = ExtLib.String.t
Set of strings 
val pkgnames : Cudf.universe -> StringSet.t
Returns the set of all names in the given universe
val add_properties : Cudf.preamble -> Cudf_types.typedecl -> Cudf.preamble
Add a new property to the given cudf preamble
val get_property : string -> Cudf.package -> string
return the value of the requested property. * emit a warning and raise Not_found if the property does not exists
val is_essential : Cudf.package -> bool
Returns true if the package is essential, that is the cudf package has a extra property named "essential" and its value is "yes"
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
Return the unique cudf id of a package in a universe
val inttovar : Cudf.universe -> int -> Cudf.package
Given a universe and a cudf id returns the corresponding package. Raise Not_found if the id does not correspond to a package.
val cudfop : (string * string) option ->
       ([> `Eq | `Geq | `Gt | `Leq | `Lt | `Neq ] * string) option
val compute_pool : Cudf.universe -> int list list array * int list array
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 normalize_set : int list -> int list
normalize_set l returns the list l without any duplicate element.

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
return a string containg either the value of the optional field "number" or the cudf version
val string_of_package : Cudf.package -> string
return a string of the form "name ( = version)"
type pp = Cudf.package -> string * string * (string * (string * bool)) list 
val pp : (Cudf_types.pkgname * Cudf_types.version -> 'a * Cudf_types.pkgname) ->
       ?fields:string list -> ?decode:(Cudf_types.pkgname -> string) -> pp
pp ?decode from_cudf pkg package pretty printer. from_cudf a function that gets a (name,cudfversion) pair and returns a (name,realversion). ?fields additional fields to print. ?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"

val default_pp : pp
default_pp default package printer. Extracts string values from a cudf package : Name, Version, Fields. Where Fields is a list of field name , value pairs . If the version of the package is a negative number, the version version if printed as "nan".
val pp_vpkg : pp -> Format.formatter -> Cudf_types.vpkg -> unit
cudf vpkglist printer.
val pp_vpkglist : pp -> Format.formatter -> Cudf_types.vpkglist -> unit
cudf vpkglist printer.
