Utilizing ++ and -- for comments

[_Pena_Botp1 ("Peña, Botp")]

Since ++ and -- wont see the light of day in ruby, can we use it for comment
notation?

define:
1. -- equal to # comment
2. --- (or more dashes) equal to =begin
   next --- (or more) equal to =end
3. ++ same comment as #1 above
4. +++ same comment as #2 above

Reasons:
1. I like "--", very clean [1]
2. We can faq ++/-- questions as: "they are used for comments"

kind regards -botp

···

--
[1] Eg

cat a1.rb

-----------------------------------
Program Name: Sample_Programming.rb
Purpose: this a sample prg showing
- same as =begin and =end comments.
clean, don't you think so? imho
-----------------------------------

p "hello, world"

p "hello, ruby" -- this is just a sample

-- I know
p "hello, world, ruby."

[George_Moschovitis]

I also think that the =begin, =end notation is not comfortable to use.
Maybe some other way of multiline comments should be added in Ruby 1.9
for example /* */ or %c{ }

I would like to see a multi-line that can nest other multi-line
comments. useful for quick and dirty code changes.

so this is a problem. Lua has some interesting comments. They are ugly
but they have some nice uses. see http://www.lua.org/pil/1.3.html
(bottom half). Any ideas how we could clean it up a bit? I like the
single hyphen toggle.

Hi --

Since ++ and -- wont see the light of day in ruby, can we use it for comment
notation?

They've already seen the light of day:

irb(main):001:0> ++ 100
=> 100
irb(main):002:0> -- 100
=> 100

And we have comment mechanisms already too

define:
1. -- equal to # comment
2. --- (or more dashes) equal to =begin
  next --- (or more) equal to =end
3. ++ same comment as #1 above
4. +++ same comment as #2 above

Reasons:
1. I like "--", very clean [1]

I understand that not everyone likes the hash-mark comment idiom. But
isn't this just another of the thousand things where it is literally
impossible for everyone to have it exactly how they want, and Matz has
gone ahead and made a reasonable decision? We can of course talk
about what looks best (and not agree), what's easiest to type (and not
agree), what will/won't make Perl/C/Java/etc. programmers feel at home
(and not agree about whether we care :-), and so forth. But that will
be true no matter what the comment mechanism is.

Come on! Real programmers don't comment their code. It was hard to
write, it should be hard to understand

That's a regex

I wouldn't mind the (* *) syntax though, and *() are all baside

Here's yer multiline comment:

g@crash:~/tmp$ cat test.rb
puts 1
%{
  puts 2
  %{
    puts 3
  }
  puts 4
}
puts 5
g@crash:~/tmp$ ruby test.rb
1
5

so this is a problem. Lua has some interesting comments. They are ugly
but they have some nice uses. see Programming in Lua : 1.3
(bottom half). Any ideas how we could clean it up a bit? I like the
single hyphen toggle.

And here's yer "single-hyphen" toggle:

g@crash:~/tmp$ cat test.rb
def q; yield end

puts 1
%q{
  puts 2
  %q{
    puts 3
  }
  puts 4
}
puts 5
g@crash:~/tmp$ ruby test.rb
1
5
g@crash:~/tmp$ cat test.rb
def q; yield end

puts 1
q{
  puts 2
  %q{
    puts 3
  }
  puts 4
}
puts 5
g@crash:~/tmp$ ruby test.rb
1
2

A regex beginning with * is illegal, but

  %/string/*2

is valid syntax.

I wouldn't mind the (* *) syntax though, and *() are all baside
eachother on my kbrd so nice and easy to type

Also,

  p(*[1,2,3])

they do
+(+(100)) -> 100
and
-(-(100)) -> 100

nothing magic

All I'm after are multi line comments - if you've got some non-icky
syntax I'm all for it

/* */

If it doesn't qualify as a regex, I'm all for it!
