It's become quite obvious from these messages and from discussion on IRC
(plus a personal experience) that the github pull request feature could use
some help.

I posted a request on githubs support page (
http://support.github.com/discussions/site/338-pull-request-comments-message-and-email)
asking that comments on requests be made more obvious.  Feel free to add
your own thoughts to that page :-)

In the meantime I am going to add some info on how to submit patches to RT
to the rakudo-github wiki as it has been decided that we will do that for
now.  We can do both, but that seems to be a lot of work for both the
submitter and pmichaud.

Happy Purim!

The word "setting" here corresponds to the way it's used in the synopses --
it's the scope containing the builtin functions and methods defined
by the language (possibly a domain-specific language -- for Perl 6
it's called the "core setting").  The word setting does not mean 
"builtin functions that are written in Perl 6".

When writing the core setting files for Rakudo we're biasing 
towards pure Perl 6 where we can -- with the intent that these 
can be shared with other implementations.  However, I continue 
to believe there will be quite a few components and operations 
that will always be implementation specific.  That's where
the inline PIR comes in for Rakudo -- we still want to use
Perl 6 syntax to declare the methods and functions (because
we need multimethods signatures, binding, type checking,
exports, etc.), but those portions of the body that we can't
yet write in Perl 6 we can at least fill in with PIR.

Perhaps we need separate places in the repository for the 
"ready to be shared" and "not ready to be shared" components
of the setting; at this early stage of development I'm thinking
it's more important to organize the code by its function 
than by whether it's pure Perl 6 or has some inline PIR.

But, if there are other implementations that would start
using Rakudo's settings files today except for the existence
of the inlined PIR parts, I'm willing to reorganize sooner
rather than later.

Regardless, I think it's important that we use the
term "setting" for its synopsis meaning -- i.e., "scope
corresponding to linguistic setting", and not use it to
mean "a set of specific files shared by implementations".

Some setting candidates

2009-03-10 Thread Patrick R. Michaud
For those who are interested in adding some of the Perl 6
builtins to Rakudo's core settings files -- I've created
a wiki page that lists some prime candidates that I think
ought to be relatively easy to convert (perhaps using inline PIR).

http://wiki.github.com/rakudo/rakudo/setting-candidates

See also the file "docs/guide_to_setting.pod" in the Rakudo
repository.

At present I'm still heavily favoring patches submitted via 
RT over those submitted via the fork queue on github.

Why is one condition 'die' and the other condition 'fail'?

Note that $list might not be something that can be shifted -- 'shift'

That was our original thought (well, the first thought after .{''}),

.{*} instead of .{'*'}, it parses and silently does the wrong thing.
So the key wants to be something that doesn't parse as a term like *

We looked at most of the keys on the keyboard...  :)

Our initial attempts in this regard didn't work well -- submissions
would contain individual commits that contained lots of false 
starts and backtracks, making it hard to see the result.

 yes

and one to its returned closure. I don't see why you assume that.
 because of the two dots
 ruoso: but .() and () are equivalent, no?
 unless where they are not :-)
 masak: isn't that what the entire discussion has been about ?
 SamB: yes.
 we're starting in on the second lap round the circle now.
 masak, .() and () are equivalent when you're dealing with variables
 I think it would DWIM to make $.a.() being the same as $.a().a()
 $foo() and $foo.() are the same

I think you should do both!  :-)

When you're committing false starts and partial implementations, you
should use rebase -i and squash those commits into a single
complete-feature commit (and thus a single patch).

If, ultimately, the subject of your branch has several pieces or takes
several steps to fully implement, each of those steps should be a
commit of their own. 

Thus our pumpking will see a series of commits that could each probably
stand on their own (though there may be some dependency ordering). And
there shouldn't be any spurious or throw-away commit messages like
"Oops, forgot to twiddle the frobnitz in the previous commit"

Just my humble opinion,

-Scott

As someone who reviews patches quite often, my advice would be exactly
the contrary -- I tend to prefer a series of small patches with long
commit messages: that way it's easier to review the logic of the whole
change. (Personal taste only.)

I think I understand the reasoning behind this change.

However, using . in particular says "boolean" to me.  How about
.<*> instead, with its suggestion of "whatever the Match found"?

Just (*...@list) or some such.

listing all files in all sub directories

2009-03-10 Thread steve
I am trying to list all files in all sub-directories and have the code
below but this is listing the . directories as well as the directories
themselves. I just want the full path filenames and not the individual
directories out. Here is what I have

#!c:/Perl/bin/Perl.exe

@ARGV = qw(.) unless @ARGV;

use File::Find;

find sub { print $File::Find::name, -d && "/", "\n"}, @ARGV

for example if structure is
c:\file.txt
c:\file2.txt
c:\one\teo.txt
c:\two\text.bmp

the output of the script when run from c:\ would be
./
./script.pl
./file.txt
./file2.txt
./one/
./one/teo.txt
./two/
./two/text.bmp

all I want is
./script.pl
./file.txt
./file2.txt
./one/teo.txt
./two/text.bmp

Thanks!

When you did more than one commit in the branch, please merge with the
---squash option, so that our dear pumpking only has to review one
patch, not multiple.
