Quoting constructs: Difference between revisions

=={{header|Nim}}==

Nim uses single quote for characters.<br/>

It uses double quotes for single line strings and triple double quotes for multiline strings.<br>

The standard module <code>strformat</code> provides interpolation in strings.<br>

Nim allows to define special strings, for instance to describe regular expressions or PEGs (parsing expression grammar).<br/>

Arrays literals are defined as a list of values between brackets.<br/>

Preceding an array literal with an @ creates a sequence literal instead.<br/>

Tuples literals are defined as a list of values between parentheses. Field names may be specified by preceding a value by the name followed by a colon.<br/>
