15.3.23 Perl Format Strings
There are two kinds of format strings in Perl: those acceptable to the
Perl built-in function printf
, labelled as ‘perl-format
’,
and those acceptable to the libintl-perl
function __x
,
labelled as ‘perl-brace-format
’.
Perl printf
format strings are described in the sprintf
section of ‘man perlfunc
’.
Perl brace format strings are described in the
Locale::TextDomain(3pm)
manual page of the CPAN package
libintl-perl. In brief, Perl format uses placeholders put between
braces (‘{
’ and ‘}
’). The placeholder must have the syntax
of simple identifiers.
