kandi X-RAY | tampio Summary
Tampio is an object-oriented language that compiles to JavaScript. Its syntax is directly inspired by the Finnish language and is therefore based on inflecting words. A Tampio file is a list of definitions, each which defines either a class, a function, a method, a comparison operator or a global variable. For example, here is a simple program that calculates the factorial of a given number. It contains two functions definitions, one variable definition and one method definition. Let’s iterate these line by line. This is the signature of the kertoma function, which has one parameter pieni luku. As you can see, the name of the parameter comes before the name of the function and is in the genitive case. The last word, on, is a keyword that separates the signature of the function and its body. This is a ternary expression. It tests if se is less than or equal to (pienempi tai yhtä suuri kuin) one (yksi). se is like this in JavaScript and always means the first parameter (here pieni luku). If the condition is true, the function returns one, (yksi). joko is a keyword that comes after the condition of riippuen siitä expression. If the condition is false (pieni luku is greater than one), the function returns the value of this expression. It is a product (kerrottuna is the multiplication operation) of pieni luku and pienen luvun edeltäjän kertoma. The right operand of kerrottuna consists of two function calls (which are similar to the signature of the function). First, the predecessor (edeltäjä) of pieni luku is calculated, and then its factorial (kertoma). The arguments of functions are in the genitive case. This is a helper function that calculates the predecessor of a number. It simply consists of a vähennettynä operator with operands se (the parameter) and yksi (one). Olkoon is a keyword that is used to define global variables. The name of the variable is pieni muuttuja and its value is a new object. The object is created using the uusi keyword and its type is the muuttuja class. jonka keyword is used to set the initial values of the fields of the object. In this case, the arvo field is initialized to nolla (zero). This line declares a new method for the sivu class. (sivu is an alias to the HTMLDocument JavaScript class.) It begins with the Kun keyword. The name of the method is avautuu and the name of the "self" object is nykyinen sivu. (As in Python, the "self" object must be named in the signature of a method.). Here we call the luetaan luku method of pieni muuttuja. The method will prompt a number from the used and store it to the arvo field of pieni muuttuja. pieni muuttuja is in the illative case, because the luetaan luku method requires that case. ja keyword is used to specify that this is the last statement in the body of the method. It is another method call, calling the näyttää method of nykyinen sivu. (An alias to HTMLDocument.write.) The argument of the method is a function call and the argument of kertoma is pienen muuttujan arvo (note the genitive case of both arguments). The field access syntax is identical to the function call syntax.

QUESTION
I have been trying to learn about functional programming, but I still struggle with thinking like a functional programmer. One such hangup is how one would implement index-heavy operations which rely strongly on loops/order-of-execution.
For example, consider the following Java code:
...ANSWER
Answered 2022-Mar-07 at 21:17This is not an index-heavy operation, in fact you can do this with a one-liner with scanl1 :: (a -> a -> a) -> [a] -> [a]:
QUESTION
I want to write a function that checks if the first list is longer than the second list and one of them can be infinite. However I can't find a working solution.
...ANSWER
Answered 2022-Mar-22 at 20:54Plain old natural numbers will not do the trick, because you can't calculate the natural number length of an infinite list in finite time. However, lazy natural numbers can do it.
QUESTION
Haskell provides a convenient function forever that repeats a monadic effect indefinitely. It can be defined as follows:
ANSWER
Answered 2022-Feb-05 at 20:34The execution engine starts off with a pointer to your loop, and lazily expands it as it needs to find out what IO action to execute next. With your definition of forever, here's what a few iterations of the loop like like in terms of "objects stored in memory":
QUESTION
I was solving a recursive problem in haskell, although I could get the solution I would like to cache outputs of sub problems since has over lapping sub-problem property.
The question is, given a grid of dimension n*m, and an integer k, how many ways are there to reach the gird (n, m) from (1, 1) with not more than k change of direction?
Here is the code without of memoization
...ANSWER
Answered 2021-Dec-16 at 16:23In Haskell these kinds of things aren't the most trivial ones, indeed. You would really like to have some in-place mutations going on to save up on memory and time, so I don't see any better way than equipping the frightening ST monad.
This could be done over various data structures, arrays, vectors, repa tensors. I chose HashTable from hashtables because it is the simplest to use and is performant enough to make sense in my example.
First of all, introduction:
QUESTION
I have a function in Haskell that is defined as follows:
...ANSWER
Answered 2021-Nov-30 at 09:42Haskell values have types. Each value has a type. One type. It can't be two different types at the same time.
Thus, since x is returned as the result of if's consequent, the type of the whole if ... then ... else ... expression is the same as x's type.
An if expression has a type. Thus both its consequent and alternative expression must have that same type, since either of them can be returned, depending on the value of the test. Thus both must have the same type.
Since x is also used in the test, it must be Bool. Then so must be y.
QUESTION
What is the syntax for a vector (array) of functions in APL?
I have tried the following but these are interpreted as a 3-train and a 2-train, respectively:
...ANSWER
Answered 2021-Nov-28 at 23:26Dyalog APL does not officially support function arrays, you can awkwardly emulate them by creating an array of namespaces with identically named functions.
QUESTION
In F# if I write
...ANSWER
Answered 2021-Nov-17 at 01:24To expand on the answer given in the comments, the first p is an immutable value, while the second p is a function. If you refer to an immutable value multiple times, then (obviously) its value doesn't change over time. But if you invoke a function multiple times, it executes each time, even if the arguments are the same each time.
Note that this is true even for pure functional languages, such as Haskell. If you want to avoid this execution cost, there's a specific technique called memoization that can be used to return cached results when the same inputs occur again. However, memoization has its own costs, and I'm not aware of any mainstream functional language that automatically memoizes all function calls.
QUESTION
I'm working trough the book Haskell in depth and I noticed following code example:
...ANSWER
Answered 2021-Nov-03 at 06:39Reader's type parameters aren't in the right order for that to be contramap for it. A Contravariant functor always needs to be contravariant in its last type parameter, but Reader is contravariant in its first type parameter. But you can do this:
QUESTION
I am experimenting with clojure's lazy sequences. In order to see when the evaluation of an item would occur, I created a function called square that prints the result before returning it. I then apply this function to a vector using map.
...ANSWER
Answered 2021-Oct-20 at 15:49Laziness isn't all-or-nothing, but some implementations of seq operate on 'chunks' of the input sequence (see here for an explanation). This is the case for vector which you can test for with chunked-seq?:

Haskell lists are constructed by a sequence of calls to cons, after desugaring syntax:

Fundamentally, Haskell list is defined like this:

Install tampio
You can use tampio like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
