Common ways to read a file in Ruby?

scmuser created the topic: Common ways to read a file in Ruby?

[code language=”css”]
File.open("my/file/path", "r") do |f|
f.each_line do |line|
puts line
end
end
# File is closed automatically at end of block
[/code]

It is also possible to explicitly close file after as above (pass a block to open closes it for you):

[code language=”css”]
f = File.open("my/file/path", "r")
f.each_line do |line|
puts line
end
f.close
[/code]
