utilizing ++ and -- for comments

Peña, Botp

2/12/2005 2:47:00 AM

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

>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."

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{ }

-g.

That's a regex

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

A regex beginning with * is illegal, but

%/string/*2

is valid syntax.

Also,

p(*[1,2,3])

That's exactly the same question that I had in mind while reading this
thread...

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!

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

--- Disable this entire section
--- My other section that holds
important documentation.
---
code ... ...
---

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

Brian.
