  • ruby - find and replace in a string for commonly used street suffix

    - by go minimal
    The post office actually publishes a list of commonly used street suffixes in addresses: http://www.usps.com/ncsc/lookups/abbr_suffix.txt I want to take this list and make a ruby function that takes a string, takes the last word ("183 main strt".split[' '].last) and if it matches any of the commonly used street suffixes ("strt"), replace it with the official Postal Service Standard Suffix ("st"). Is there a better way to approach this than a massive str.sub.sub.sub.sub.sub?

  • Confused about NoMethodError in Ruby

    - by E L
    In a simple Ruby example, I'm getting an error that does not occur in irb. name = "Joe" def say_hi "\"Hi there!\" said #{self}" end response = name.say_hi puts response This code should return, "Hi there!" said Joe. It works perfectly fine in irb. However, when I attempt to put the same code in a file and run the file, I get this error: say_hi.rb:8:in `<main>': private method `say_hi' called for "Joe":String (NoMethodError) Any suggestion about why this happens?

  • Count the number of lines in a file with Ruby, without reading entire file into memory

    - by smnirven
    I'm processing huge data files (millions of lines each). Before I start processing I'd like to get a count of the number of lines in the file, so I can then indicate how far along the processing is. I am using Ruby, and because of the size of the files, it would not be practical to read the entire file into memory just to count how many lines there are. Does anyone have a good suggestion on how to do this?

  • Way to partialy match a Ruby string using Regexp

    - by Fabiano PS
    I'm working on 2 cases: assume I have those var: a = "hello" b = "hello-SP" b = "not_hello" 1 - Any partial matches I want to accept any string that has the var a inside, so b and c would match. 2 - Patterned match I want to match a string that has a inside, followed by '-', so b would match, c does not. I am having problem, because I always used the syntax /expression/ to define Regexp, so how dinamicaly define an RegExp on Ruby??

  • Checking deployed port in ruby on rails application

    - by john chan
    Is there an elegant way to check which port you deployed a ruby on rails application using mongrel? I could not find a directive (i.e. such as #{RAILS_ROOT} which contains the root directory of the application) that I can use to perform a check. I need this to do a check since I am deploying the same application on different ports and I need the app to do different things according to the port that is being accessed. Any help would be appreciated, Thanks
