P5lcfirst - Implement Perl's lcfirst() / ucfirst() built-ins
use P5lcfirst;
say lcfirst "FOOBAR"; # fOOBAR
with "ZIPPO" {
say lcfirst; # zIPPO
}
say ucfirst "foobar"; # Foobar
with "zippo" {
say ucfirst; # Zippo
}
This module tries to mimic the behaviour of the lcfirst and ucfirst functions of Perl as closely as possible.
lcfirst EXPR
lcfirst Returns the value of EXPR with the first character lowercased.
This is the internal function implementing the "\l" escape in
double-quoted strings.
If EXPR is omitted, uses $_.
This function behaves the same way under various pragmata, such as
in a locale, as "lc" does.
ucfirst EXPR
ucfirst Returns the value of EXPR with the first character in uppercase
(titlecase in Unicode). This is the internal function implementing
the "\u" escape in double-quoted strings.
If EXPR is omitted, uses $_.
This function behaves the same way under various pragma, such as
in a locale, as "lc" does.
