Here's a Ruby "read file" example program that shows how to read a file as one string. You just have to pass a file name in to the
get_file_as_string method, and this Ruby method will read in all the records from the file, and return the contents of the file as a string.
def get_file_as_string(filename) data = '' f = File.open(filename, "r") f.each_line do |line| data += line end return data end ##### MAIN ##### xml_data = get_file_as_string 'Pizza.hbm.xml' # print out the string puts xml_data
As you can see from this example, I'm using this method to read in a Hibernate XML configuration file, which I'm about to parse. However, in this example I'm just using
puts to write the file out to my screen to make sure I'm reading it correctly (instead of parsing it using an XML parser, which I hope to show shortly).
There’s just one person behind this website; if this article was helpful (or interesting), I’d appreciate it if you’d share it. Thanks, Al.
I think this will work even better:
You can also just use File.read(path). I don't know why it's not listed in the Ruby File class doc (http://www.ruby-doc.org/core/classes/File.html), but it works.
File.read is listed in the IO class. The File class can act like an IO object sometimes.
