I want to be able to break the line inside the brackets without having the "inconsistant brackets" error.
Here's a example:
select.someclass.something{data: {max_amount: o.max_amount_clean, max_amount: o.min_amount_clean, fee: o.fee_clean}}
Thanks
I'm not sure if I understand, but if the argument is a hash and not a block, like it seems, you could do
select.someclass.something(
{data:
{max_amount: o.max_amount_clean,
max_amount: o.min_amount_clean,
fee: o.fee_clean}}
)

I want to have this kind of lists:
asdasdas
aqweqwe
Instead of
asdasdasdas
jasdasdasda
Please help
Have a look at the Markdown syntax guide. In it's chapter about lists it says:
Unordered lists use asterisks, pluses, and hyphens — interchangably —
as list markers:
* Red
* Green
* Blue
is equivalent to:
+ Red
+ Green
+ Blue
and:
- Red
- Green
- Blue

For instance 1 is made of 2 dashes, 8 is made of 7 dashes and so on.write a function that takes this string message as an input and returns a corresponding value in terms of a number. This number is the count of dashes in the string message.
String has a count method:
"abc--de-f-".count('-') #=> 4
Just get a string with nothing but the dashes from your input string, and then check the length of that string:
dash_string = input_string.gsub(/[^-]/, '')
number = dash_string.length
You might want to subtract 1 from that answer based on your examples, bearing in mind that a string with no dashes would turn into -1 in that case.

Randomly output text from array to view - RAILS
It is not really well formated question ... You should be more precise about what you want, what you are using, etc.
Assuming you are using Rails 3, ERB for HTML generation:
# in your controller:
file_as_array = IO.readlines('filename.txt')
random_line = rand(file_as_array.size)
#my_random_string = file_as_array[random_line]
# in your view:
<%= #my_random_string %>

Corona/Lua how to sort a table of strings from shortest to longest
Assuming your table is a indexed table and not a keyed one try
test = {'123','1234','1245','1','12'}
table.sort(test, function(a,b) return #a<#b end)
for i,v in ipairs(test) do
print (i,v)
end
The important line here is
table.sort(test, function(a,b) return #a<#b end)
Words will only sorted by length and order within matching lengths will be arbitrary. If you want to sort by additional criteria, extend the function for the sort
eg function(a,b) return #a<#b end

I am trying to read values from a .txt file and keep getting the above error. My code reads:
file <- readFile "films.txt"
let database = (read file :: [Film])
and Film is a data type I declared as:
type Film = (String, String, Int)
Still quite new to Haskell so have no idea how to parse a string back into the required type. Sort of assumed it would be nice and do it for me like it does with writeFile!
Any hints?
