paramsrequire

paramsrequire is a command-line utility and Python library designed to validate and manage required parameters in scripts and applications. Its primary function is to ensure that specific arguments or configuration values are present before proceeding with execution, thereby preventing errors caused by missing data.

The tool allows developers to define a set of parameters that are mandatory. If any of these required parameters are not provided during runtime, paramsrequire will raise an error, typically printing a helpful message indicating which parameters are missing. This helps in early detection of configuration issues and makes the application more robust.

paramsrequire can be integrated into Python projects by importing its library. This allows for programmatic definition of required parameters and their validation within the application's code. It supports various data types and can often handle default values for optional parameters, while strictly enforcing the presence of those marked as required.

The command-line interface of paramsrequire offers a straightforward way to check parameter presence for scripts that might be invoked from a shell. This is particularly useful in automation scripts or when integrating with other command-line tools. The utility aims to simplify the process of parameter validation, making code more readable and less prone to runtime failures due to incomplete input.
