0
>>> isvalidatom('>=media-libs/test-3.0')
1

Parameters:

• atom (String) - The depend atom to check against

Returns: Integer

One of the following: 1) 0 if the atom is invalid 2) 1 if the atom is valid

Return the operator used in a depstring.

>>> get_operator(">=test-1.0")
'>='

Example usage:

>>> isjustname('media-libs/test-3.0')
0
>>> isjustname('test')
1
>>> isjustname('media-libs/test')
1

Parameters:

• mypkg - The package atom to check
• mypkg - String

Returns: Integer

One of the following: 1) 0 if the package string is not just the package name 2) 1 if it is

Checks to see if a package is in category/package-version or package-version format, possibly returning a cached result.

Example usage:

>>> isspecific('media-libs/test')
0
>>> isspecific('media-libs/test-3.0')
1

Parameters:

• mypkg (String) - The package depstring to check against

Returns: Integer

One of the following: 1) 0 if the package string is not specific 2) 1 if it is

Takes a Category/Package-Version-Rev and returns a list of each.

Parameters:

• mydata (string) - Data to split
• silent (Boolean (integer)) - suppress error messages

Returns:

1. If each exists, it returns [cat, pkgname, version, rev]
2. If cat is not specificed in mydata, cat will be "null"
3. if rev does not exist it will be '-r0'
4. If cat is invalid (specified but has incorrect syntax) an InvalidData Exception will be thrown

Returns: String

The package category/package-version

Return the category-package-version with any operators/slot specifications stripped off

Example usage:

>>> dep_getcpv('>=media-libs/test-3.0')
'media-libs/test-3.0'

Parameters:

• mydep (String) - The depstring

Returns: String

The depstring with the operator removed

Pull a listing of USE Dependencies out of a dep atom.

Example usage:

('foo','-bar')

Parameters:

• depend (String) - The depstring to process

Returns: List

List of use flags ( or [] if no flags exist )

# Imported from portage.dep

        * repo

Retrieve the slot on a depend.

Example usage:

>>> dep_gettag('app-misc/test#2.6.23-sabayon-r1')
'2.6.23-sabayon-r1'
