Strings¶
Unlike in other languages, strings in squirrel are primitive types and immutable. That means you can’t change the value of a string but will need to copy and change it in another variable.
The default value of strings is an empty string with a length of 0.
The type keyword for strings is string
.
To create strings, simply write the text of the literals in "
quotes.
Verbatim Strings¶
Verbatim strings do not escape sequences. They begin with a @
token before a regular string literal.
Verbatim strings can also extend over multiple lines.
If they do they include any white space between the matching string quotes.
string a = "simple string\nover two lines"
string b = @"simple string
over two lines"
Assert( a == b )
However, a doubled quotation mark within a verbatim string is replaced by a single quotation mark.
string a = "extra quotation mark\""
string b = @"extra quotation mark """
Assert( a == b )
Assets¶
Assets and strings are internally the same but at compile time they are different types.
Assets are used to reference a specific resource (often in rpak files).
The type keyword for assets is asset
.
Asset literals are regular string literals prefixed with the $
token. Verbatim strings can’t be an asset.
asset a = $"my/resource"
Northstar added the StringToAsset
function that allows converting any string into an asset.
