This recently happened with the EveryBuddy program. In the case of the Objective-C front-end for GCC, it didn't even get to lawyers.

You still claim copyright, but you are at least implicitly licensing it under perl's license. Public domain is a disclaimer of copyright. It seems to me that it's much harder to infer that, by submitting a patch, someone meant to say: "I give up all copyright on this work" than it is to infer: "I am submitting this copyrighted work of mine to a project whose license I know, and therefore it's under the same license."

I don't recall any of the compiler texts I have read over the years talking about formal methods for writing such a "partial programs are acceptable" parser.

Perhaps, since we are doing recursive decent, we could have a user-definable error function. If all possible errors have well-defined types, the caller could define an error function that informs rather than croaks and could prompt like this: foo$ print "Hello world RET foo (unclosed double-quote)$ Inside, this would be something like (sorry for writing in pseudo-Perl, instead of pseudo-C): $PROMPT = "foo$"; $interp = new Perl::Language::Interpeter(); $done = 0; my $handleError = sub ($) { my($errorID) = @_; if (! $errorID) { $interp-Eval($parseTree); $done = 1; } if ($errorID == $UNCLOSED_DOUBLE_QUOTE) { $PROMPT = "foo (unclosed double-quote)$"; } [...] } while (! $done) { print "$PROMPT "; $string .= STDIN; chomp $string; $parseTree = $interp-Parse($string, $handleError); } -- Bradley M.

This isn't a bad thing, but it means it's an inappropriate solution to the problem. We might as well write perl 6 in perl. I think that Java is closer to system-level programming than Perl, and certainly not as close as C. However, I don't think we should dismiss it out of hand because people don't do a lot of systems programming C. some of the things we are going to build for C (if that's what we pick), are already there automatically in Java, such as: * garbage collection for internal data structures * vtables And, it will make the barrier for entry for new internals hacker lower. I just don't think we should dismiss Java out of hand because it isn't traditionally used for systems-level programming. 1) Targeting a single compiler, no matter whose it is, is a bad idea. We're writing in a *language*, not for a compiler. Targeting a specific compiler restricts us even more than choosing a language. I would note that if we write in Java, we aren't targeting a single compiler, although at the moment, the only efficient compiler for Java might be GCJ. 2) GCC produces slow code on all platforms where there's an alternative.

Whether or not it is slow is not my concern. My concern is *can* we support it on architectures that don't have a native C compiler (i.e., the JVM).

Simon Cozens [EMAIL PROTECTED] wrote: Patches welcome. Well, this isn't a patch, but if you really meant patches literally and not figuratively, I can provide one if you let me know. ;) Of the suggestions that have been advanced so far, four are worthy of more consideration: C, C++, Java and a specially-designed Perl Implementation Language. (PIL) Java is portable and gives us OO, but it's slow and ugly. I am probably the biggest proponent of the "use Java to implement Perl" camp. And, on this front, I would like to comment. First, "ugly" is a matter of taste, and I don't think we should let that be a deciding factor. Every programming language is ugly in one way or another. As for "slow", this will be helped by GCJ, the new GCC 3.0 front-end for Java. Java will compile to native code, via GCC. GCJ is not yet ready for prime time, so I certainly understand reluctance on building on infrastructure that isn't done yet. However, if we, as a team, decide that Java is a real contender, I will volunteer to start monitoring GCJ's progress. It might turn out that GCJ will be ready "just-in-time" for us to use it to implement Perl. ;) I know there is great resistance to requiring GCC, and I remember those threads. I believe this was mostly from the VMS camp. So, is there a native-code Java compiler for VMS? We need to think about the data structures that will replace SVs, HVs and AVs. I predict that such structures will be extensively used by the internals themselves, so they need to be fast and efficient. One concern that I have about the data structure design thus far (and I believe I wrote an RFC about this) is that we should try to resist the temptation to "talk in C" too soon. Most of the ideas I have seen thrown around are filled with C-isms. Of course, that's totally reasonable, if it helps people think about the issues. However, I would like it to be possible for a programmer of language Foobar to take the specification of the data structures and implement them directly in Foobar without too much trouble. The fewer C-isms in the high-level spec, the easier such a task will be. As the RFC 125 discussed, I think the interfaces for data structures and other APIs to be somewhat object-oriented. Basically, something like: An SV must answer the following methods: UnicodeString toString() # returns the scalar value as Unicode string ASCIIString toString() # returns the scalar value as an ASCII string int32 toInt() # returns the scalar value as a 32-bit int. or something like that. We seem to have settled on a vtable model for SVs, which is cool. vtables are a strategy for implementing a particular OO-style interface. I'd like to see higher level documentation developed before we get too far into the detailed data structure design. Again, if we're going to make a Perl a platform for building languages, we need to make it easy to replace Perl's parser with a parser for other languages, and the way to do this is to have a clearly defined interface by which programmers can write their replacement. I think this is very important. It is also important that the specification of the Parser itself be clear. If the parser is to be written in a subset of Perl, that subset must be somewhat clearly defined. =head2 Memory Allocation Memory allocation's pretty much a solved problem, so this shouldn't need to require much thought. [...] =head2 Garbage Collection I would like to note that GCC has actually switched to using garbage collection to manage its *internal* data structures rather than a traditional C memory management system. The GCC team has been pleased with both the performance and ease of use. The argument is: "Computers do a better job at memory allocation than humans do by hand, so let the computer do it!"

In other words, I am arguing that writing the parser in a subset of Perl makes the easy jobs a bit harder, but the hard jobs possible. :) Someday, for the JVM port of Perl, I'd like to support eval(). The only way to do that on the JVM natively is to have a parser that compiles to JVM code, too. When I brought this problem to Per Bothner (well-known GCC hacker, and author of the Scheme to JVM port, Kawa), he said: "Well, the best way would be if a parser for Perl was written in a subset of Perl. Then, you could bootstrap a simple compiler in Java that supports that subset, and that would buy you the full parser." I really like that idea. While C is ubiquitous for most computing tasks, it isn't ubiquitous on native JVM platforms. You really need to have everything available in Java or a language that compiles to the JVM efficiently. C will likely eventually compile to to the JVM, but it'll never be as native as Java is. Consider, too, that people may want to implement Perl in another way, perhaps radically different ways, down the line. It will be a nice jump-start for them if there is some subset of Perl that buys you a full Perl parser. So, I'd like to see the parser written in a simple subset of Perl or some other small language that can be bootstrapped fast.
