Hi,
Which syntax do you like most?
1. if
-----
# block-by-indentation
if a == 10
print a
# Java/C, etc style
if(a == 10)
{
print(a);
}
# Ruby style
if a == 10
print a
end
2. Rails' link_to
-----------------
link_to 'Show', :action => :show, :id => @post
link_to 'Show', action: 'show', id: @post
link_to 'Show', action: :show, id: @post
link 'Show', to: {action: 'show', id: @post}
3. Classes
----------
# Ruby
class Foo
def method
print 'hi'
end
end
# Indentation
class Foo
def method
print 'hi'
4. Loop
-------
5.times i
print i
5.times do |i|
print i
end
for 0, 5, i
print i
end
5. Map
------
arr = [1, 2, 3]
arr.map{|e| e * 2}
arr.map do |e|
e * 2
end
arr.map(e, e * 2)
arr.map(e * 2) # variable is 'e' (element) by default
or maybe:
arr = new Array();
arr.add(1);
arr.add(2);
arr.add(3);
for(i = 0; i < arr.length(); i++)
{
arr = arr * 2;
}
;-)
--------------
I am trying to imagine the 'perfect' scripting language (for me, at
least ;-)). Ruby is close, but I prefer a different syntax in some
cases. I find the indentation-based code-blocks nicer than
do...end-blocks.
I also prefer this:
arr.map(e, e * 2)
or:
# parentheses are optional
arr.map e, e * 2
to this:
arr.map{|e| e * 2}
I'm not sure whether or not default variable names like this:
arr.map(e * 2)
are a good thing...
What do YOU like, and why?
Thanks in advance,
Jules
