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.
