Unicode.Guards (Unicode function guards for Elixir v1.0.1)
View SourceDefines a set of guards that can be used with Elixir functions.
Each guard operates on a UTF8 codepoint since the permitted operators in a guard clause are restricted to simple comparisons that do not include string comparators.
The data that underpins these guards is generated from the Unicode character database and therefore includes a broad range of scripts well beyond the basic ASCII definitions.

Functions
Guards whether a UTF8 codepoint is a space character.
This is the Unicode definition of those characters that horizontal space (space, non-breaking space etc) as well as the horizontal tab character.
Guards whether a UTF8 codepoint is a currency symbol character.
Guards whether a UTF8 codepoint is a digit character.
This guard will match any digit character from any Unicode script, not only the ASCII decimal digits.
Guards whether a UTF8 codepoint is a graphic character.
This is the Unicode definition of those characters that are visible. It is defined as those characters that are non-space, non-control and non-surrogate.
Guards whether a UTF8 codepoint is a lower case character.
The match is for any UTF8 character that is defined in Unicode to be an lower case character in any script.
Guargs where a UTF8 codepoint is a printing character.
This is the Unicode definition which is a combination of the
[:graph:] set and the [:blank:] set.
Guards whether a UTF8 codepoint is a printable.
The definition of what is printable is the same as
used by String.printable?/1
Guards whether a UTF8 codepoint is a unicode quote symbol character.
This includes the Unicode set Pi, Pf and
other characters documents in this Wikpedia article.
