* utils: new "hybridmethod" decoratorJan Pokorný2015-08-111-0/+8
| | | | | | | | | | | Similar to hybridproperty: first parameter of the decorated method is flexibly bound to either the instance or the class depending on the context of invokation. Effectively, the only difference is that hybridmethod is expected to be passed arguments, unlike with property where it is called directly (w/o parameters) upon access.

* utils: try avoiding clash of special keys in kwargsJan Pokorný2015-08-111-7/+7
| | | | | | | | ...in filterdict_* lambdas where (now) _fn_ is a special key. Also adjust the callers where needed. Signed-off-by: Jan Pokorný <jpokorny@redhat.com>
* utils: add lazystring decorator/wrapper over eval'd stringJan Pokorný2015-02-261-0/+26
| | | | | | | | Caching of the value is implicit, can be disabled by the respective flag, e.g., if the value depends on some condition that may change in a repeated string yielding. Signed-off-by: Jan Pokorný <jpokorny@redhat.com>
* ext-plugins/lib-general: string_{list,set} + conversion filterJan Pokorný2015-01-091-1/+1

* utils: arg2wrapped: make sure list on input is on outputJan Pokorný2014-11-141-2/+3
| | | | | | Previously, the list was deconstructed and reconstructed as a tuple. Signed-off-by: Jan Pokorný <jpokorny@redhat.com>
* format (+utils): make format compatibility check more liberalJan Pokorný2014-10-211-1/+8
| | | | | | | ... so as to fix a regression introduced with more explicit format declarations in the filter "signatures". Signed-off-by: Jan Pokorný <jpokorny@redhat.com>
* plugin_registry: fix issue with non-discoverable pluginsJan Pokorný2014-09-171-1/+7
| | | | | | | | | | | | | | | | | | There are "native" plugins, such as XML under `format` module. The problem with these is that once they are dropped (`PluginRegistry.setup(reset=True)`), they cannot be re-discovered any more (the first discovery is usually implicit through the import + metaclass machinery). Now we can also remove a hack in `PluginRegistry.discovery()` that used to inject such "native" plugins implicitly (but till the whole registry got restarted!) if full search was requested. Thanks to Travis CI for exposing the issue because of the different ordering of the unit tests (subsequently reproduced at me with `./run-tests tests.{format_manager.Injection,command_manager.Default}`).

* command/format: pass declared cmd context subset to Format objectJan Pokorný2014-06-181-0/+21
| | | | | | | | | | | | | | This subset is declared with 'context_specs' and is being built on the metaclass level in the top-down, extending (additive/non-subtractive) manner (just like the set of methods is growing monotonously top-down the hierarchy). Currently, only 'validator_specs' (mapping protocols to the somewhat abstract "validator spec", '' key being used as a failback) is of interest this way, and can be used as an on-off validation toggle on user's request (by convence, '' value stands for off state).
