perl 2.0 (no announcement message available)perl-2.0
Some of the enhancements from Perl1 included: * New regexp routines derived from Henry Spencer's. o Support for /(foo|bar)/. o Support for /(foo)*/ and /(foo)+/. o \s for whitespace, \S for non-, \d for digit, \D nondigit * Local variables in blocks, subroutines and evals. * Recursive subroutine calls are now supported. * Array values may now be interpolated into lists: unlink 'foo', 'bar', @trashcan, 'tmp'; * File globbing. * Use of <> in array contexts returns the whole file or glob list. * New iterator for normal arrays, foreach, that allows both read and write. * Ability to open pipe to a forked off script for secure pipes in setuid scripts. * File inclusion via do 'foo.pl'; * More file tests, including -t to see if, for instance, stdin is a terminal. File tests now behave in a more correct manner. You can do file tests on filehandles as well as filenames. The special filetests -T and -B test a file to see if it's text or binary. * An eof can now be used on each file of the <> input for such purposes as resetting the line numbers or appending to each file of an inplace edit. * Assignments can now function as lvalues, so you can say things like ($HOST = $host) =~ tr/a-z/A-Z/; ($obj = $src) =~ s/\.c$/.o/; * You can now do certain file operations with a variable which holds the name of a filehandle, e.g. open(++$incl,$includefilename); $foo = <$incl>; * Warnings are now available (with -w) on use of uninitialized variables and on identifiers that are mentioned only once, and on reference to various undefined things. * There is now a wait operator. * There is now a sort operator. * The manual is now not lying when it says that perl is generally faster than sed. I hope.
