[Obsolete] Spelling

Drupal Core uses US English spelling for all source code, including comments and names.

Core code is automatically checked for spelling by CSpell. 

Spelling of CSpell

For in line documentation settings use all lower case for cspell. For example, // cspell:ignore.

Ignore word(s) in a file

Use the cspell:ignore directive. The words are listed alphabetically with a single space between the words. Use multiple lines to meet the number of characters per line limit.

<?php

// cspell:ignore first-word second-word

Disable CSpell by line

if it's not in English or a nonsense string (for example, a random string in a test) disable CSpell for that line. Note that cspell is lower case.

<?php

// cspell:disable-next-line
$token = 'PxOHfS_QL-T01NjBgu7Z7I04tIwMp6La5vM-mVxezbU';
use Drupal\foo\Bar;

Disable CSpell for multiple lines

For multiple lines, use disable before the lines and enable after. Note that cspell is lower case.

<?php

// cspell:disable
$lorem1 = 'Lorem ipsum dolor sit amet in libero.';
$lorem2 = 'Ut fermentum est vitae metus orci.';
// cspell:enable

See the cspell development tool page for more details.
