pkgcore.ebuild.atom module

gentoo ebuild atom, should be generalized into an agnostic base

class pkgcore.ebuild.atom.atom(*a, **kw)

Bases: AndRestriction

Currently implements gentoo ebuild atom parsing.

Should be converted into an agnostic dependency base.

blocks

blocks_strongly

property blocks_temp_ignorable

cnf_solutions(full_solution_expansion=False)

returns solutions in CNF (conjunctive normalized form) of this instance

Parameters:

full_solution_expansion – controls whether to expand everything (break apart atoms for example); this isn’t likely what you want

cpvstr

evaluate_conditionals(parent_cls, parent_seq, enabled, tristate=None)

evaluate_depset = None

property get_atom_without_use_deps

Return atom object stripped of USE dependencies.

intersects(other)

Check if a passed in atom “intersects” this restriction’s atom.

Two atoms “intersect” if a package can be constructed that matches both:

• if you query for just “dev-lang/python” it “intersects” both “dev-lang/python” and “>=dev-lang/python-2.4”

• if you query for “=dev-lang/python-2.4” it “intersects” “>=dev-lang/python-2.4” and “dev-lang/python” but not “<dev-lang/python-2.3”

USE and slot deps are also taken into account.

The block/nonblock state of the atom is ignored.

property is_simple

iter_cnf_solutions(full_solution_expansion=False)

returns solutions in CNF (conjunctive normalized form) of this instance

Parameters:

full_solution_expansion – controls whether to expand everything (break apart atoms for example); this isn’t likely what you want

iter_dnf_solutions(full_solution_expansion=False)

generater yielding DNF (disjunctive normalized form) of this instance.

Parameters:

full_solution_expansion – controls whether to expand everything (break apart atoms for example); this isn’t likely what you want

negate = False

negate_vers

property no_usedeps

alias to get_atom_without_use_deps

op

repo_id

restrictions

slot

slot_operator

subslot

type = 'package'

use

property weak_blocker

alias to blocks_temp_ignorable

class pkgcore.ebuild.atom.transitive_use_atom(*a, **kw)

Bases: atom

cnf_solutions(full_solution_expansion=False)

returns solutions in CNF (conjunctive normalized form) of this instance

Parameters:

evaluate_conditionals(parent_cls, parent_seq, enabled, tristate_filter=None)

is_simple = False

iter_dnf_solutions(full_solution_expansion=False)

generater yielding DNF (disjunctive normalized form) of this instance.

Parameters:

full_solution_expansion – controls whether to expand everything (break apart atoms for example); this isn’t likely what you want
