A generic file/URL handler that presents options via dmenu. It takes a URL or file path as an argument, shows a list of actions (open, copy, etc.), and executes the chosen action. The script is self-contained, uses standard shell commands, and can be reused in any dmenu-based environment to handle arbitrary inputs.

Opens files or URLs based on their MIME type, determined by the `file` command. It dispatches images to nsxiv, videos to mpv, PDFs to zathura, etc. The pattern of using a case statement on MIME types is clean and extensible, making it reusable for any system that needs to open files in appropriate viewers.

Detects file extension and runs the appropriate compiler or formatter. Supports LaTeX, groff, Markdown (pandoc), C, and more. It is self-contained, requires only standard utilities, and can be extracted into any project that needs automatic compilation of source files based on extension.

Generates shell aliases, vim shortcuts, lf keybindings, and other configuration snippets from simple bookmark files (bm-dirs, bm-files). This demonstrates a non-obvious pattern of creating a single source of truth for common directories and files, then generating bindings for multiple applications. Reusable for any environment that wants consistent shortcuts across tools.
