Linebreak::CLI

Build Status Code Climate

Description

Linebreak::CLI is a Ruby command-line tool for conversion of text between linebreak encoding formats of unix, windows or mac.

Before Linebreak 2.0.0 this tool was part of the linebreak gem. Earlier versions of Linebreak were called BreakVerter.

Features / Problems

This project tries to conform to:

Additional facts:

  • Written purely in Ruby.
  • Intended to be used with Ruby 1.8.7 or higher.
  • Cryptographically signed gem and git tags.

Synopsis

This documentation defines the public interface of the software. Don't rely on elements marked as private. Those should be hidden in the documentation by default.

Command-line tool

The default output encoding is unix. You can also choose mac and windows.

linebreak encode --system windows unix.txt windows.txt

If no target file is specified the output will be sent to STDOUT.

linebreak encode --system windows mac.txt > windows.txt

You can set the default with the environment variable LINEBREAK_SYSTEM.

export LINEBREAK_SYSTEM=mac

linebreak encode windows.txt mac.txt

If you do not specify an output file, output will be put to STDOUT. If you also do not specify an input file, input will be expected from STDIN.

You can also detect the linebreak systems contained in a file in the following way:

linebreak encodings windows_mac.txt

If you want to ensure that a file contains the exact encodings systems you specified, you can use the following command:

linebreak encodings --ensure unix,windows,mac unix.txt

The results will be outputted. In case of a file containing other linebreak encoding systems there will be an exit code of 1.

It is also possible to specify multiple input files or none to expect input from STDIN.

Requirements

  • Ruby 1.8.7 or higher
  • user-choices

Installation

On *nix systems you may need to prefix the command with sudo to get root privileges.

There is a high security installation option available through rubygems. It is highly recommended over the normal installation, although it may be a bit less comfortable. To use the installation method, you will need my gem signing public key, which I use for cryptographic signatures on all my gems.

Add the key to your rubygems' trusted certificates by the following command:

gem cert --add aef-gem.pem

Now you can install the gem while automatically verifying it's signature by the following command:

gem install linebreak-cli -P HighSecurity

Please notice that you may need other keys for dependent libraries, so you may have to install dependencies manually.

Normal

gem install linebreak-cli

Automated testing

Go into the root directory of the installed gem and run the following command to fetch all development dependencies:

bundle

Afterwards start the test runner:

rake spec

If something goes wrong you should be noticed through failing examples.

Development

Bug reports and feature requests

Please use the issue tracker on github.com to let me know about errors or ideas for improvement of this software.

Source code

This software is developed in the source code management system Git. There are several synchronized mirror repositories available:

You can get the latest source code with the following command, while exchanging the placeholder for one of the mirror URLs:

git clone MIRROR_URL

Tags

The final commit before each released gem version will be marked by a tag named like the version with a prefixed lower-case "v", as required by Semantic Versioning. Every tag will be signed by my OpenPGP public key which enables you to verify your copy of the code cryptographically.

Add the key to your GnuPG keyring by the following command:

gpg --import aef-openpgp.asc

This command will tell you if your code is of integrity and authentic:

git tag -v [TAG NAME]

Contribution

Help on making this software better is always very appreciated. If you want your changes to be included in the official release, please clone my project on github.com, create a named branch to commit and push your changes into and send me a pull request afterwards.

Please make sure to write tests for your changes so that I won't break them when changing other things on the library. Also notice that I can't promise to include your changes before reviewing them.
