Range Operators Binary ".." is the range operator, which is really two different operators depending on the context. In list context, it returns a list of values counting (up by ones) from the left value to the right value. If the left value is greater than the right value then it returns the empty list. The range operator is useful for writing foreach (1..10) loops and for doing slice operations on arrays. In the current implementation, no temporary array is created when the range operator is

NAME SYNOPSIS DESCRIPTIONMultiple packages DIAGNOSTICS AUTHOR COPYRIGHT AND LICENSE NAME AutoSplit - split a package for autoloading SYNOPSIS autosplit($file, $dir, $keep, $check, $modtime); autosplit_lib_modules(@modules); DESCRIPTION This function will split up your program into files that the AutoLoader module can handle. It is used by both the standard perl libraries and by the MakeMaker utility, to automatically configure libraries for autoloading. The autosplit interface splits the s

our VARLIST our TYPE VARLIST our VARLIST : ATTRS our TYPE VARLIST : ATTRS our makes a lexical alias to a package (i.e. global) variable of the same name in the current package for use within the current lexical scope. our has the same scoping rules as my or state, meaning that it is only valid within a lexical scope. Unlike my and state, which both declare new (lexical) variables, our only creates an alias to an existing variable: a package variable of the same name. This means that when use st

${^TAINT} Reflects if taint mode is on or off. 1 for on (the program was run with -T), 0 for off, -1 when only taint warnings are enabled (i.e. with -t or -TU). This variable is read-only. This variable was added in Perl v5.8.0.

Quote-Like Operators q/STRING/ 'STRING' A single-quoted, literal string. A backslash represents a backslash unless followed by the delimiter or another backslash, in which case the delimiter or backslash is interpolated. $foo = q!I said, "You said, 'She said it.'"!; $bar = q('This is it.'); $baz = '\n'; # a two-character string qq/STRING/ "STRING" A double-quoted, interpolated string. $_ .= qq (*** The previous line contains the naughty word "$1".\n) if /\b(tcl|java|python

NAME DESCRIPTION NAME perlrepository - Links to current information on the Perl source repository DESCRIPTION Perl's source code is stored in a Git repository.

Binding Operators Binary "=~" binds a scalar expression to a pattern match. Certain operations search or modify the string $_ by default. This operator makes that kind of operation work on some other string. The right argument is a search pattern, substitution, or transliteration. The left argument is what is supposed to be searched, substituted, or transliterated instead of the default $_ . When used in scalar context, the return value generally indicates the success of the operation. The exc
