class::Char
summary::ascii character
categories:: Core
description::
Chars may be written as literals using the $ sign. For example $a, $b, $c.
See link::Reference/Literals::
Chars may be created from link::Classes/Integer::s using the methods link::Classes/Integer#-asAscii:: and link::Classes/Integer#-asDigit::.
classmethods::
method::nl
Returns code::($\n)::
method::ff
Returns code::($\f)::
method::tab
Returns code::($\t)::
method::space
Returns code::($ )::
method::comma
Returns code::($\,)::
method::bullet
Returns a bullet character (•) in SuperCollider.app on OSX, but a simple asterix (*) on other frontends.
This method is not recommended, since it's actually not cross-platform.
instancemethods::
private:: archiveAsCompileString
subsection::conversion
method::ascii
returns:: the integer ascii value of a Char.
method::digit
returns:: an integer value from 0 to 9 for chars $0 to $9, and values 10 to 35 for chars $a to $z
or $A to $Z.
method::toUpper
returns:: the upper case version of a char. Nonalphabetic chars return themselves.
method::toLower
returns:: a lower case version of a char. Nonalphabetic chars return themselves.
subsection:: Testing
method::isAlpha
returns:: whether the char is an alphabetic character.
method::isAlphaNum
returns:: whether the char is an alphabetic or numeric character.
method::isPrint
returns:: whether the char is printable.
method::isPunct
returns:: whether the char is a punctuation character
method::isSpace
returns:: true if the char is white space.
method::isDecDigit
returns:: true if the char is a decimal digit $0 to $9.
method::isFileSafe
returns:: true if the char is safe for use as in a filename.
excludes the path separators / and :
discussion::
code::
for(0,255,{ arg i;
var a;
[i,a = i.asAscii,a.isAlphaNum,a.isPrint,a.isPunct,a.isControl].postln;
});
