python - What's a good resource for starting to write a programming language, that's not context free? -

-

i'm looking write programming language fun, of resource have seen writing context free language, wish write language that, python, uses indentation, understanding means can't context free.

a context-free grammar is, simply, 1 doesn't require symbol table in order correctly parse code. context-sensitive grammar does.

the d programming language example of context free grammar. c++ context sensitive one. (for example, t*x declaring x pointer t, or multiplying t x ? can tell looking t in symbol table see if type or variable.)

whitespace has nothing it.

d uses context free grammar in order simplify parsing it, , simple tools can parse (such syntax highlighting editors).

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
