|
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.
|
|
|

|
|
|
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.
