Aliases: line-length Parameters: linelength, codeblocks, tables (number; default 80, boolean; default true)
This rule is triggered when there are lines that are longer than the configured line length (default: 80 characters). To fix this, split the line up into multiple lines.
This rule has an exception where there is no whitespace beyond the configured line length. This allows you to still include items such as long URLs without being forced to break them in the middle.
You also have the option to exclude this rule for code blocks and tables. To
do this, set the code_blocks and/or tables parameters to false.
Code blocks are included in this rule by default since it is often a requirement for document readability, and tentatively compatible with code rules. Still, some languages do not lend themselves to short lines.

Я сделаю упор на теорию, но уже глубже. Так, в прошлом издании я часто использовал неточную терминологию, откровенно ступил с определением монады, прогнал какую-то пургу с ФВП, ни словом не обмолвился о функторных и иных законах, почти не рассказал о паттерн-матчинге и использовал мало примеров реального кода. В этом издании я постараюсь исправить все эти ошибки.- Read upRead up

Функция `map` ожидает два аргумента, это отражено в её типе. Но что будет, если применить её не к двум аргументам, а лишь к одному? В этом случае произойдёт ещё одно «магическое» превращение, называющееся частичным применением (англ. partial application) функции. Частичным называют такое применение, когда аргументов меньше чем ожидается.- Read upRead up

Функция `map` получила лишь первый аргумент, а где же второй? Второй, как мы уже знаем, будет получен ею уже потом, после того, как мы подставим это выражение на место функции `ten`. Но что же происходит с функцией `map` до этого? А до этого с ней происходит частичное применение. Понятно, что она ещё не может выполнить свою работу, поэтому, будучи применённой лишь к одному аргументу, она возвращает ЛФ! Сопоставим с типом функции `map`, и всё встанет на свои места:- Read upRead up

наша функция будет всегда возвращать первое выражение, строку `I don't know such a standard...`, и это вполне ожидаемо: первая же проверка гарантированно даст нам `True`, ведь с образцом `_` совпадает всё что угодно. Таким образом, общий образец следует располагать в самом конце, чтобы мы попали на него лишь после того, как не сработали все остальные образцы.- Read upRead up

Вторая причина — изменившаяся цель книги. Я намеренно сузил круг рассматриваемых здесь тем. Теперь книга всецело посвящена основам языка, поэтому не ищите здесь рассмотрения специфических тем. Я не очень-то верю в идею book-all-in-one, книга для новичков должна быть книгой для новичков. Вы не встретите здесь ни примеров реализации 3D-движка, ни рассказа о работе с PostgreSQL, ни повествования о проектировании игры для Android. Всё это можно делать с Haskell, но подобным темам посвящены другие публикации, которые несомненно будут вам по плечу после прочтения моей книги.- Read upRead up

И это важно. В процессе чтения вы заметите, что я периодически поднимаю вопросы и как бы оставляю их без ответа. Это делается вполне осознанно: ответы обязательно будут даны, но в последующих главах, там, где это будет наиболее уместно. Поэтому перепрыгивание с главы на главу может вас запутать.- Read upRead up

Функция `tail` формирует другой список, представляющий собою всё от первоначального списка, кроме головы. Обратите внимание на новую функцию `print`. В данном случае мы не могли бы использовать нашу знакомую `putStrLn`, ведь она применяется к значению типа `String`, в то время как функция `tail` вернёт нам значение типа `[String]`. Мы ведь помним про строгость компилятора: что ожидаем, то и получить должны. Функция `print` предназначена для «стрингификации» значения: она берёт значение некоторого типа и выводит это значение на консоль уже в виде строки.- Read upRead up

Вот опять эти маленькие буквы! Помните, я обещал рассказать о них? Рассказываю: малой буквой принято именовать полиморфный (англ. polymorphic) тип. Полиморфизм — это многообразность, многоформенность. В данном случае речь идёт не об указании конкретного типа, а о «типовой заглушке». Мы говорим: «Функция `map` применяется к функции из какого-то типа `a` в какой-то тип `b` и к списку типа `[a]`, а результат её работы — это другой список типа `[b]`». Типовой заглушкой я назвал их потому, что на их место встают конкретные типы, что делает функцию `map` очень гибкой. Например:- Read upRead up
