pauljm / asciiify.rb
Created September 17, 2015 23:34
Strategy for handling non-ASCII with Mail
# Escape non-ASCII characters and forward slashes as unicode escape sequences,
# but with forward slashes instead of backslashes, since backslashes already have meaning
def asciiify(str)
str.unpack('U*').map { |i|
(i == 47 || i == 92 || i > 127) ? "/u" + i.to_s(16).rjust(4, '0') : i.chr
}.join
end
# Decode "forward slashed" unicode escape sequences

Quick and dirty utility to list all the objects in an S3 bucket with a certain prefix and, for any whose key matches a pattern, read the file line by line and print any lines that match a second pattern. Adjust constants as appropriate. Usage: sbt 'run <AWS access key ID> <AWS secret key>'
/**
* Directory structure should be:
* - project_root
* - build.sbt (see below)
* - src
* - main
* - scala
* - S3Inspect.scala
*/
package s3inspect
