Title
Description
The world of Ruby is a big and beautiful one. Like Cane from Kung-Fu, you could spend a lifetime wandering it's surface and never lack for an abundance of wonder. But there is an even larger world outside its walls that is also filled with amazing things. Based on lessons learned writing C extensions, Java extensions as well embedding interpreters (v8) and applications (Jenkins) inside Ruby, This talk will take you through the best ways to dress up any citizen of the galaxy in order to make it indistiguishable from one of our beloved planet Ruby.

In the presentation titled "Placing Things into Other Things" by Charles Lowell at LoneStarRuby Conf 2013, the speaker delves into the complexities of developing command line interfaces (CLIs) and proposes solutions to common issues faced by developers in this domain. The talk emphasizes the importance of enhancing the developer experience, particularly through improved CLI tools. Key points discussed include: - **Challenges of CLI Output**: The speaker highlights the common problems related to managing output to the terminal, where direct writing to standard output can lead to clashes, particularly in larger applications. - **Output Formatting**: There are issues in sharing formatting code across various output generators, which can make applications complex and hard to manage. An example given involves a CLI created with Thor, emphasizing the need for a tailored help display. - **Integration of External Streams**: Integrating output from other applications can complicate how information is presented, particularly when external output doesn't match the application’s style. - **Progress Indicators**: Highlighting the difficulty of providing user feedback during long operations, the need for efficient and clear feedback mechanisms is discussed with reference to progress bars. - **Decoding and Validation of Inputs**: The speaker points out the challenges in transforming strings into meaningful objects, advocating for a structured approach to decoding and validation. - **Plugin System Necessity**: As CLIs grow, implementing a robust plugin system becomes necessary to manage additional functionalities. This helps break down complex applications into manageable parts. - **Proposed Solutions**: Solutions mentioned include using middleware to streamline output management, implementing templates for better organization of output, and structuring input through forms which helps define expected input and ensures validations. - **Adaptation of Web Principles**: The speaker compares command line tools to web applications, advocating for the adoption of established frameworks and paradigms to enhance CLI development. - **Introduction of MVCLI**: The speaker introduces MVCLI, a project on GitHub, as a framework that organizes CLI development and offers extensive plug-in capabilities. Overall, the presentation concludes with a reinforcement of treating command line applications as complete entities rather than simple scripts, emphasizing the importance of established structures and methodologies to facilitate their development to enhance user and developer experiences.
