Tags: line_length
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.

Функциональное программирование — своеобразное гетто посреди мегаполиса нашей индустрии. Доля функциональных языков пока ещё очень мала, и многие разработчики побаиваются знакомства с этими языками, и с Haskell в особенности. Моя цель — разрушить этот страх. Вероятно, вы слышали, что Haskell — это что-то архисложное, сугубо научное и непригодное для реальной жизни? Читайте дальше, и вскоре вы убедитесь в обратном.

Функция `checkProtocol` объявлена как принимающая аргумент типа `Transport`, а применяется она к значению, порождённому конструктором `TCP`. В данном случае конструкция `case-of` сравнивает аргумент с конструкторами. Именно поэтому нам не нужна функция `otherwise`, ведь никаким иным способом, кроме как с помощью трёх конструкторов, значение типа `Transport` создать невозможно, а значит, один из конструкторов гарантированно совпадёт.

Конечно, у этой медали есть и обратная сторона — время, затрачиваемое на компиляцию. Вам придётся свыкнуться с этой мыслью: внесли изменения в проект — будьте добры скомпилировать. Однако утешением вам пусть послужит тот факт, что преимущества статической проверки куда ценнее времени, потраченного на компиляцию.

И вот только здесь мы реально вычисляем второй аргумент, складывая три единицы. Вы спросите, почему же мы накапливали эти сложения вместо того, чтобы делать их сразу? Потому что мы ленивы: раз результат сложения понадобился нам лишь на последней итерации, значит до этой итерации никакого сложения не будет, ведь лень вынуждает нас откладывать работу до конца.

Что же касается проблемы space leak, то к счастью, существуют способы обнаружения функций, шибко прожорливых до памяти. В самом деле, представьте себе большой проект, тысячи функций, и что-то кушает гигабайты памяти. Как найти виновного? Этот процесс называют ещё «space leak профилированием». Рассказывать об этом здесь я не стану, материал довольно объёмный. Но для особо любопытных привожу ссылку на неплохую англоязычную статью по теме: [Chasing a Space Leak in Shake](http://neilmitchell.blogspot.am/2013/02/chasing-space-leak-in-shake.html).

Даже несмотря на то, что функция `justifyLeft` есть только в модуле `Data.Text` и никаких коллизий с `Prelude` нет, мы обязаны указать, что эта функция именно из `Data.Text`. В больших модулях qualified-импорт бывает полезен: с одной стороны, гарантированно не будет никаких конфликтов, с другой, мы сразу видим, откуда родом та или иная функция.
