I think what you’re looking for is chapter §6.2.7 from the C11 standard, Compatible type and composite type, (emphasis mine) All declarations that refer to the same object or function shall have compatible type; otherwise, the behavior is undefined. and related to compatible type, Two types have compatible type if their types are the same. … Read more
Update: pytest-namespace hook is deprecated/removed. Do not use. See #3735 for details. You mention the obvious and least magical option: using a fixture. You can apply it to entire modules using pytestmark = pytest.mark.usefixtures(‘big_dict’) in your module, but then it won’t be in your namespace so explicitly requesting it might be best. Alternatively you can … Read more
A potentially important difference in functionality is that window.myGrid can be deleted, and var myGrid can not. var test1 = ‘value’; window.test2 = ‘value’; console.log( delete window.test1 ); // false ( was not deleted ) console.log( delete window.test2 ); // true ( was deleted ) console.log( test1 ); // ‘value’ ( still accessible ) console.log( … Read more
It’s possible, but heap allocation is not allowed directly. Heap allocation is performed at runtime. Here are a few examples: static SOME_INT: i32 = 5; static SOME_STR: &’static str = “A static string”; static SOME_STRUCT: MyStruct = MyStruct { number: 10, string: “Some string”, }; static mut db: Option<sqlite::Connection> = None; fn main() { println!(“{}”, … Read more
To use global variables inside a function, you need to do global <varName> inside the function, like so. testVar = 0 def testFunc(): global testVar testVar += 1 print testVar testFunc() print testVar gives the output >>> 0 1 Keep in mind, that you only need to declare them global inside the function if you … Read more
Yes, maybe not in general. However you can do it with functions. The thing you want to do is to have the function’s global to be empty. You can’t replace the globals and you don’t want to modify it’s content (becaus that would be just to get rid of global variables and functions). However: you … Read more
Yes, all members of a are guaranteed to be initialised to 0. From section 3.5.7 of the C89 standard If an object that has static storage duration is not initialized explicitly, it is initialized implicitly as if every member that has arithmetic type were assigned 0 and every member that has pointer type were assigned … Read more
ActiveState has a recipe titled Cᴏɴsᴛᴀɴᴛs ɪɴ Pʏᴛʜᴏɴ by the venerable Alex Martelli for creating a const module with attributes which cannot be rebound after creation. That sounds like what you’re looking for except for the upcasing — but that could be added by making it check to see whether the attribute name was all … Read more
If you are running two separate processes, then they won’t be sharing the same globals. If you want to pass the data between the processes, look at using send and recv. Take a look at http://docs.python.org/library/multiprocessing.html#sharing-state-between-processes for an example similar to what you’re doing.
Yes, use a closure: functionName($someArgument, function() use(&$variable) { $variable = “something”; }); Note that in order for you to be able to modify $variable and retrieve the modified value outside of the scope of the anonymous function, it must be referenced in the closure using &.
