LSRC Name Picker

Hey all.
I seem to get this error whenever I run my program.

-----------------------------------------------------------|
ERROR

@names { |f| lines = f.readlines
^
namePicker-cli.rb:60: syntax error, unexpected ‘}’, expecting kEND
-----------------------------------------------------------|
What does this mean? Here is my code:

Tally ho, I’m going to write this

as best I can. Store the picked names

to a file, and then that will be the checker.

LINE 58

     lines.puts unless $. == selected.chomp

Suggestions? Any?

English is like a pseudo-random number generator - there are a
bajillion rules to it, but nobody cares.

snip

  @names { |f| lines =  

f.readlines ### LINE 58
lines.puts unless $. == selected.chomp

Untested, but shouldn’t this be

 @names.each{ |f| lines =

f.readlines ### LINE 58
lines.puts unless $. == selected.chomp
}

It’s Ruby’s way of telling you that your code doesn’t make sense.

Basically, you are defining a block for an instance variable here,
but only methods can take blocks in Ruby. I assume you meant to call
some iterator and forgot to include the method name.

Hope that helps.

I was trying this:
@names = open(’.names.txt’, ‘w+’)
in initialize, and then write to that file later on. Is there a
better way to do this?

Hope that helps.
It did!

This is fine and in that case you don’t need the block at all. You
can just write to the file with:

@names.puts “…”
