Hello!
I would like to redirect large chunks of text to a specific
resource (file, stderr, etc). I thought that the code below
would do my job:
def |>(s)
myputs %Q|#{s}
end
def <|
>
end
in a similar to eruby fashion, ie:
>>
I don't know much, but I guess
#{42} is a special number.
<|
Unfortunately, I get a syntax error. Any hints?

Well, that doesn’t work for a number of reasons. For starters it
should basically quote “\nend\n…”. And I don’t think <| and |> are
valid names…

eRuby basically replace “%>anything<%” with “puts
‘anything’”. Everything else is left as is.

Depends on what you’re trying to do. If you just want chucks of text
in your code:
puts <<EOF
something here…
EOF
If you want eRuby behaviour… Why not just use eRuby? I’ve used it as
templating for emails.

a = Object.new

end
a.send(“|>”, “a string”) # a string

Yes. Actually I am aware of why this produces syntax errors. It was
easier to paste it as an idea instead of describing what I was looking
for.
eRuby basically replace “%>anything<%” with “puts
‘anything’”. Everything else is left as is.
Does something like CPP exist in Ruby? I.e. a way to define some symbols
that expand during the code. In a C-ish way:
#define <% myputs %Q|
#define %> |

I produce chunks of text in various places in my program and I like an
interface such as the one eruby uses. Currently, the closest I can get is:
myputs %Q|
...
...

It would be nice if I could substitute the above with 2 distinct Object’s
operators.

I don’t want to increase my project’s depedencies.

OKOK, they’re valid names, but particular useful names:
irb(main):005:0> a.|> “test”
NameError: undefined method `|’ for #Object:0x40286370
seems the parser sees > as an operator, which is fair.

well, why don’t you use ERB then ? it has been included in the core
lib since a long time

C/C++ has a preprocessor, Ruby doesn’t.
However using ‘eval’ can easily let you do similar things.

In fact there are two operators, namely “|” and “>”. And expr “|” “>” is
not valid Ruby syntax.
You can do things like
puts <<EOM
This
is
a
multi
line
String
that
can
get
quite
long
and
even
contain
expressions
like
#{1+2}.
EOM
puts %{
This
is
double
quote
text.
\tsee?
#{1+2}
}
%Q{} works also, as well as “”.
puts %q{
This
is
single
quote
text.
\tsee?
#{1+2}
}
…
