Hi guys :blush:, this my sem mini project Student_Authentication_System. I have used html,css code as front-end & php as server-side language and additional mysql database to store the student informations. I have beautified webpage using Animated.css & Hover.css libraries :heart_eyes:. You can see the page here... but I really recommend visiting the page to see the small animations that really makes page more amazing :new_moon_with_face:.

QUESTION
I'm trying to write a Haskell-style language parser in ANTLR4, but I'm having some issues with function application. It parses as right associative rather than left associative
...ANSWER
Answered 2021-Dec-09 at 13:59As @sepp2k pointed out, | expression expression
will correct your issue.
ANTLR defaults to left associativity., but you were overriding that with the (expression)+
in trying to gather all the expressions.
Of course, this will give you a parse tree of (expr (expr (expr f) (expr "a")) (expr "b"))
but this is probably more in keeping with a Haskell approach to function application than just a list of expressions.
BTW, precedence only comes into play when operators are involved. Having StringLiteral
before LSquareParen
his no effect on precedence since there's no ambiguity in determining the correct parse tree to derive. You may find that your OperatorApplicationExpresion
alternative gives "surprising" results as it will evaluate all operators left-to-right, so a + b * c
will be evaluated as "(a + b) * c" and this violates arithmetic norms (maybe it's what you want however).
QUESTION
I keep receiving an error/lint which reads Variable 'self.item' used before being initialized
. This message only appears when I seemingly add a @State
of type Date
(see commented line below).
Variable item
is a CoreData
value that I'm attempting to update through a form. All of the other required data types (int, string, data, etc.) all work as expected.
I'm fairly confident that this is an issue which stems from my lack of experience with Swift or declarative-style languages in general, but I'm also wary that it could be a compiler issue as I seem to run into a few of those as well.
