| 7 Renovation of Perl 1.0 | |
| 8 ====================== | |
| 9 | |
| 10 By Christophe Staiesse, 3 January 2014 | |
| 11 Contact: chastai@skynet.be | |
| 12 | |
| 13 The aim of this project is to adapt the source code of Perl 1.0 to make it | |
| 14 compilable on modern operating systems. | |
| 15 | |
| 16 It is based on Perl 1.0 patchlevel 29 that I have reconstituted from 39 Usenet | |
| 17 articles (see Usenet/ directory). | |
| 18 | |
| 19 The project is hosted at bitbucket: https://bitbucket.org/chastai/perl-1.0 | |
| 20 Check the git history or the file perl.diff to see the changes made. | |
| 21 | |
| 22 The source code of Perl 1 is not difficult to follow: the front-end (perl.y | |
| 23 and perly.c) generates an abstract syntax tree from a Perl program. The tree is | |
| 24 then executed by the interpreter in cmd.c. | |
| 25 | |
| 26 The debugger (perldb) is also interesting to study. To use it, you'll need to | |
| 27 assign the $perl variable to the correct path to the perl executable | |
| 28 (e.g.: "./perl"). Type h to get help. | |
| 29 | |
| 30 Status | |
| 31 ------ | |
| 32 | |
| 33 Perl 1 should compile and run on BSD systems, Linux, Mac OS X and other | |
| 34 Unix-like operating systems. | |
| 35 | |
| 36 It has been successfully tested on Debian Wheezy, FreeBSD 9.2, Mac OS X Lion | |
| 37 and OpenBSD 5.4. All tests passed but many warnings are still generated by the | |
| 38 C compiler. | |
| 39 | |
| 40 Compilation | |
| 41 ------------ | |
| 42 | |
| 43 $ ./Configure -d (or ./Configure to answer the questions manually) | |
| 44 $ make depend (if not already done by Configure) | |
| 45 $ make | |
| 46 $ make test | |
| 47 | |
| 48 If you need to regenerate Configure (and config_h.SH and confmagic.h): | |
| 49 - Install dist (which contains metaconfig). I would advise to get the latest | |
| 50 version available on Sourceforge: http://sourceforge.net/projects/dist/. | |
| 51 - Run packinit | |
| 52 - Run metaconfig -M | |
| 53 | |
| 54 Documentation | |
| 55 ------------- | |
| 56 | |
| 57 Read the manual to have an idea of what features are supported in Perl 1. The | |
| 58 plain text version is in perl.man.txt. | |
| 59 | |
| 60 To do | |
| 61 ----- | |
| 62 - Make it run on Windows (with Cygwin?) | |
| 63 | |
| 64 - Test a2p (Awk to Perl converter) and s2p (Sed to Perl | |
| 65 converter) in the x2p/ directory. | |
| 66 | |
| 67 - Fix bugs and write additional tests. |
