Configuration flag for deactivating an annex

[jjhugues]

In some cases, one may want to deactivate an annex from the regular parsing phase. For instance apply analyses that do not depend on them

One may imagine a configuration parameter for that, that would simply deactivate the corresponding registered parser

An open question could be: how about analysis? We could have a warning if EMV2 is disabled when trying to run FHA or FTA

We need the following:

• [ ] A preference dialog that lists the installed annexes with a checkbox that allows deselecting the annex
• [ ] Modification of parser, validator, etc, to check is processing of some annex is disabled.

@jjhugues did you intend the flag to be project specific (project A can use annex B, but project C can NOT use annex B) or is the flag should be applied to all projects (if annex B flag is unchecked, then it can NOT be used in project A and project C)

@AaronGreenhouse Do you know if it is possible to access preferences from stand alone java programs (jar files) that you can run from command line to process aadl file?

The flag should be project specific

@asazonova I don't know for sure, but I think it would probably work. The core Workspace preference and project properties data structures are not UI-specific.

@lwrage

for workspace preference, we use final IPreferenceStore store = OsateCorePlugin.getDefault().getPreferenceStore(); for project preference, we use final IScopeContext context = new ProjectScope(project); final Preferences prefs = context.getNode(PREFS_QUALIFIER);

This Preferences prefs object does not have a method to set a default value. However, unlike workspace preference, for projects we set the preference explicitly with prefs.putBoolean(annexExtensionId.toLowerCase(), value); - see implementation below: @Override public void putBoolean(String key, boolean value) { wrapped.putBoolean(key, value); }

this one does not have a check if oldValue == newValue, which is good for us, it will just set the preference to false without ignoring it

Conclusion,

• workspace preference has a default of true and only resets the value if it has changed. Here, setting a default value guarantees that we can turn off the preference and it will be set to false.
• project preference does not have a default value, but it is capable of setting a value to false on first try. So if the value is set, then we can use that, if the value is not set then we use 'true' as a preference is turned on (this also assumes that the flag 'use project preferences' is turned on for this specific project)
