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 your gem name right after releasing it to RubyGems.org. Please do not do it earlier due to security reasons. Alternatively, replace this section
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.
