Rot135
A small tool to apply ROT13 to a given file or STDIN.
It 'encrypts' texts by applying ROT13
to the characters 'a'-'z' and 'A'-'Z'. no other chacacters will be changed, no
one with diacritics such as 'š', nor symbols or (decimal) digits.
You can use the command option -5 or --five (hyphen five) to transform decimal digits in a similar way. i.e.
transforming using the following table
Input | Output |
---|
0 | 5 |
1 | 6 |
2 | 7 |
3 | 8 |
4 | 9 |
5 | 0 |
6 | 1 |
7 | 2 |
8 | 3 |
9 | 4 |
Installation
TODO: Replace UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG

with instructions to install your gem from git if you don't plan to release to RubyGems.org.
Install the gem and add to the application's Gemfile by executing:
$ bundle add rot135
If bundler is not being used to manage dependencies, install the gem by executing:
$ gem install rot135
Usage
rot135
takes a file name (or STDIN), reads it runs it through ROT13 and outputs the result to STDOUT.
- Use the command line option
-5
or --five` to convert digital digits instead of alphabetical letters. - Use
-b
or --both
to apply both transformations.
