Examples

from oelint_parser.cls_stash import Stash

# create an stash object
_stash = Stash()

# add any bitbake like file
_stash.AddFile("/some/file")

# Resolves proper cross file dependencies
_stash.Finalize()

# Use _stash.GetItemsFor() method to filter the stash

Get variables from the files

To get variables from the stash object do

from oelint_parser.cls_item import Variable

# get all variables of the name PV from all files
for x in _stash.GetItemsFor(attribute=Variable.ATTR_VAR, attributeValue="PV"):
    print(x)

this returns the raw object representation

Expand raw variables

from oelint_parser.cls_item import Variable
from oelint_parser.helper_files import expand_term

# get all variables of the name PV from all files
for x in _stash.GetItemsFor(attribute=Variable.ATTR_VAR, attributeValue="PV"):
    # raw unexpanded variable
    print(x.VarValue)
    # raw unexpanded variable without quotes
    print(x.VarValueStripped)
    # expanded variable
    print(expand_term(stash, "/some/file", x.VarValueStripped))
    # single items from a list
    print(x.get_items())
    # expanded single items from a list
    print([expand_term(stash, "/some/file", y) for y in x.get_items()])

Working with constants

For this library a few basic sets of constant information, such as basic package definitions, known machines and functions are needed. Those can be easily modified, in case you have additional information to add/remove/modify.

The actual database is not accessible by the user, but a few methods in the oelint_parse.constants.CONSTANT class do exist. Each of the method accepts a dictionary with the same key mapping as listed below (multilevel paths are displayed a JSON pointer)

Backward compatibility with rule/constant file

Originally offered support for rule or constant files is offered by the two new methods

• oelint_parse.constants.CONSTANT.AddFromRuleFile
• oelint_parse.constants.CONSTANT.AddFromConstantFile

NOTE these interfaces are considered legacy interfaces and will be removed at some point in the future
