WOPR
A markup language for creating rich terminal reports, presentations, and infographics using XML syntax.
What is WOPR?
WOPR is a markup language for creating rich terminal reports, presentations, and infographics using XML syntax. It allows developers to define visual elements like charts and maps in a structured format and render them directly in the terminal. The project solves the problem of visualizing data and creating presentations within command-line environments without relying on graphical interfaces.
Developers and system administrators who work extensively in terminal environments and need to create dashboards, reports, or presentations. It's particularly useful for those building command-line tools that require data visualization or status reporting.
WOPR provides a simple, XML-based way to create terminal visualizations without complex graphics libraries. Its integration with blessed widgets and support for both online and offline viewing makes it versatile for sharing reports while maintaining data privacy when needed.

- Generating data visualizations in terminal environments
- Creating slide presentations for technical demos
- Sharing infographics via curl commands
- Developing offline-capable reporting tools
Not Ideal For
- Projects requiring graphical user interfaces or web-based dashboards
- Teams that prefer JSON or YAML configuration over XML markup
- Environments where terminal access is restricted, such as in some cloud or mobile applications
Pros & Cons
Pros
Uses a straightforward XML syntax that developers familiar with web technologies can quickly adopt, as shown in the sample bar chart example.
Leverages the blessed and blessed-contrib libraries to provide charts, maps, and text boxes without needing to build from scratch, expanding visualization options.
Supports online sharing via curl, URL-based reports, and offline local installation, offering flexibility for different deployment and privacy needs.
The 12x12 grid system allows exact placement of elements on the terminal screen, enabling structured and organized reports, as detailed in the layout section.
Cons
The reference online viewer is explicitly warned against for secret data, requiring users to set up their own server for secure applications, which adds complexity.
Viewing reports involves intricate curl commands with escaping and parameter adjustments, as seen in the examples, making it error-prone for casual use.
Windows users need to install specific fonts for optimal viewing, and the tool is best suited for Unix-like terminals, reducing its accessibility.
