* Remove "register" declarationsKarl Williamson2012-11-241-3/+3
| | | | | | | This finishes the removal of register declarations started by eb578fdb5569b91c28466a4d1939e381ff6ceaf4. It neglected the ones in function parameter declarations, and didn't include things in dist, ext, and lib, which this does include
* Omnibus removal of register declarationsKarl Williamson2012-08-181-16/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes most register declarations in C code (and accompanying documentation) in the Perl core. Retained are those in the ext directory, Configure, and those that are associated with assembly language. See: http://stackoverflow.com/questions/314994/whats-a-good-example-of-register-variable-usage-in-c which says, in part: There is no good example of register usage when using modern compilers (read: last 10+ years) because it almost never does any good and can do some bad. When you use register, you are telling the compiler "I know how to optimize my code better than you do" which is almost never the case. One of three things can happen when you use register: The compiler ignores it, this is most likely. In this case the only harm is that you cannot take the address of the variable in the code. The compiler honors your request and as a result the code runs slower. The compiler honors your request and the code runs faster, this is the least likely scenario. Even if one compiler produces better code when you use register, there is no reason to believe another will do the same. If you have some critical code that the compiler is not optimizing well enough your best bet is probably to use assembler for that part anyway but of course do the appropriate profiling to verify the generated code is really a problem first.

* perl5.000 patch.0e: fix various non-broken things in the x2p/ directoryAndy Dougherty1995-01-181-3/+4
| | | | | | | | | | | | | | This patch fixes various non-broken things in the x2p/ directory. Mostly, I've supplied function prototypes to satisfy particularly picky compilers. I've also updated Makefile.SH to know that the byacc-generated a2p.c is now included with the distribution so that we no longer need to go looking for yacc/bison/byacc and deal with various library issues or command line options to support those various compiler compilers. I've included a2p.c generated by byacc-1.9. Larry, feel free to use your own from byacc-1.8 instead.

* perl 3.0: (no announcement message available)perl-3.000Larry Wall1989-10-181-3/+8
| | | | | | | | | | | | | | A few of the new features: (18 Oct) * Perl can now handle binary data correctly and has functions to pack and unpack binary structures into arrays or lists. You can now do arbitrary ioctl functions. * You can now pass things to subroutines by reference. * Debugger enhancements. * An array or associative array may now appear in a local() list. * Array values may now be interpolated into strings. * Subroutine names are now distinguished by prefixing with &. You can call subroutines without using do, and without passing any argument list at all. * You can use the new -u switch to cause perl to dump core so that you can run undump and produce a binary executable image. Alternately you can use the "dump" operator after initializing any variables and such. * You can now chop lists. * Perl now uses /bin/csh to do filename globbing, if available. This means that filenames with spaces or other strangenesses work right. * New functions: mkdir and rmdir, getppid, getpgrp and setpgrp, getpriority and setpriority, chroot, ioctl and fcntl, flock, readlink, lstat, rindex, pack and unpack, read, warn, dbmopen and dbmclose, dump, reverse, defined, undef.
* perl 2.0 (no announcement message available)perl-2.0Larry Wall1988-06-051-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | 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.
* a "replacement" for awk and sedperl-1.0Larry Wall1987-12-181-0/+237
[ Perl is kind of designed to make awk and sed semi-obsolete. This posting will include the first 10 patches after the main source. The following description is lifted from Larry's manpage. --r$ ] Perl is a interpreted language optimized for scanning arbitrary text files, extracting information from those text files, and printing reports based on that information. It's also a good language for many system management tasks. The language is intended to be practical (easy to use, efficient, complete) rather than beautiful (tiny, elegant, minimal). It combines (in the author's opinion, anyway) some of the best features of C, sed, awk, and sh, so people familiar with those languages should have little difficulty with it. (Language historians will also note some vestiges of csh, Pascal, and even BASIC-PLUS.) Expression syntax corresponds quite closely to C expression syntax. If you have a problem that would ordinarily use sed or awk or sh, but it exceeds their capabilities or must run a little faster, and you don't want to write the silly thing in C, then perl may be for you. There are also translators to turn your sed and awk scripts into perl scripts.
