osje

osje is a small, fast, and extensible command-line interface (CLI) application framework written in Python. Its primary purpose is to simplify the process of creating sophisticated command-line tools and scripts. osje provides a structured way to define commands, arguments, options, and subcommands, making it easier to manage complex CLI applications.

The framework is built around the concept of decorators, which are used to annotate Python functions and classes, thereby defining their role within the CLI. This declarative approach allows developers to focus on the core logic of their application rather than the intricacies of argument parsing and command handling. osje automatically generates help messages based on the defined structure, enhancing the usability of the CLI tool for end-users.

Key features of osje include automatic argument parsing, subcommand nesting, type checking for arguments, and the ability to generate documentation. It also supports features like command aliases, default values for arguments, and validation of input. The extensibility of osje allows developers to integrate custom logic and plugins, further tailoring the framework to specific project needs. Its design emphasizes simplicity and developer productivity, making it a suitable choice for both small utility scripts and larger, more complex command-line applications.
