configuration

Options to run MacSyFinder can be specified in a Configuration file. The API described below handles all configuration options for MacSyFinder.

The macsypy.config.MacsyDefaults hold the default values for macsyfinder whereas the macsypy.config.Config hold the values for a macsyfinder run.

configuration API reference

MacsyDefaults

class macsypy.config.MacsyDefaults(**kwargs)

Handle all default values for macsyfinder. the default values must be defined here, NOT in argument parser nor in config the argument parser or config must use a MacsyDefaults object

__init__(**kwargs)

Parameters

kwargs – allow to overwrite a default value. It mainly used in unit tests

To define a new default value just add an attribute with the default value

__weakref__

list of weak references to the object (if defined)

Config

class macsypy.config.Config(defaults, parsed_args)

Handle configuration values for macsyfinder. This values come from default and ar superseded by the configuration files, then the command line settings.

__init__(defaults, parsed_args)

Store macsyfinder configuration options and propose an interface to access to them.

The config object is populated in several steps, the rules of precedence are

system wide conf < user home conf < model conf < (project conf | previous run) < command line

system wide conf = etc/macsyfinder/macsyfinder.conf user home conf = ~/.macsyfinder/macsyfinder.conf model conf = model_conf.xml at the root of the model package project conf = macsyfinder.conf where the analysis is run previous run = macsyfinder.conf in previous run results dir command line = the options set on the command line

Parameters

• defaults (a MacsyDefaults object) –

• parsed_args (a argspace.Namescape object) – the command line arguments parsed
