java based interpreter and regexes
15734 [wayne.blair@] I have been thinking about the java based ruby interpreter project, and I

| | + 15750 [wayne.blair@] Would the goal be to make it compatible with the ruby C regex implementation
| | | + 15753 [sma@3p us .d] Well, with "it" I was actually referring to Ruby as whole, not to the
| | | + 15758 [decoux@mo lo] Not really a superset because it give incompatibilities. For example,
| | + 15752 [decoux@mo lo] There are differences between perl5 and ruby for the regexp engine.
| | + 15759 [ser@ma s. er] Hm.  I was comparing Ruby 1.6.4 against IBM's Java 1.3 on Linux.
| |   + 15764 [glen@en bl d] Hm... it seems to me that a regex implementation that was simply an

| |   + 15775 [sma@3p us .d] I was using a PII 450 with 256 MB running Windows 98.
| |     + 15796 [benoit.cerri] I did the test too both using jdk1.4 and the ruby 1.6.3 as distributed by

  | 16041 [wayne.blair@] Thanks, checking it out now.  Certainly better documented.

  | | + 16059 [sma@3p us .d] One could perhaps try to use Java Debug API which allows to modify
  | + 16058 [sma@3p us .d] That would be definitely an option.  I'd vote for Squeak as it comes
  |   16060 [glen@en bl d] What about GNU Smalltalk? Not being a Smalltalk expert I can't verify

    + 16078 [hipster@xs a] While the Ruby grammar might not be LL(k) as-is (haven't got a proof),
      16079 [matz@ze ab t] It's good to hear you'ce got the work done that much.

Compilation helper
15735 [elanthis@us ] I've run into a few issues in my project AweMUD in trying to embed Ruby in relation to compilation.  I'm using automake/autoconf, but I can't find an easy way to detect/configure the settings for compiling in the Ruby library (library and include paths, basically).
15737 [glen@en bl d] Hm... I have begun a group of Autoconf macros for Python, am about to

Ruby Programming Practice

+ 15744 [hal9000@hy e] Some other people will have more valuable opinions than mine.
+ 15745 [r2d2@ma .a c] I would probably put a placeholder in the superclass just to remind myself
+ 15746 [guillaume.ru] "John Kaurin" <jkaurin@home.com>
+ 15749 [wayne.blair@] This is a fairly common practice when taking advantage of polymorphism.
+ 15760 [ser@ma s. er] Well, I'd say that this is not good programming practice.  Better would

+ 15802 [matz@ze ab t] I think it's OK.  I even call this a template pattern.

Challenges of java interpreter
15754 [wayne.blair@] To create a java interpreter for ruby, ruby would ideally be coded in itself
+ 15755 [decoux@mo lo] [ruby-talk:14893]
| + 15761 [ser@ma s. er] C is pretty famous for (practically) bootstrapping itself this way.

  | 15824 [feldt@ce ch ] Agreed, but if you want to go all the way... ;-)

    15825 [feldt@ce ch ] And a bright side it sure is. Even I'm not sure I can agree with your

eRuby file suffix
15777 [ingen.eposta] Just a proposal: How about using ".erb" as the file suffix for eRuby

      15902 [mirian@co mi] *grin*  I like this image.  I didn't understand the different between
      15922 [mike@le to .] So what about a String#to_int method that would raise an exception (or return nil) if the string is not a pure number represented in a string?
