setwhere

setwhere is a command-line utility designed for manipulating configuration files, particularly those in a JSON or YAML format. Its primary function is to allow users to programmatically update specific values within these structured data files. This is useful in scripting and automation tasks where configuration settings need to be changed dynamically without manual editing.

The utility operates by taking a file path, a key path (representing the location of the value to be changed), and the new value as input. The key path can be a simple key name for a top-level setting, or a more complex path using dot notation (e.g., `database.connection.port`) to navigate nested structures. setwhere supports various data types for the new value, including strings, numbers, booleans, and arrays.

setwhere aims to provide a reliable and straightforward way to manage configuration drift and deploy applications with tailored settings. It is often used in continuous integration and continuous deployment (CI/CD) pipelines to ensure that applications are deployed with the correct environment-specific configurations. The tool's simplicity makes it easy to integrate into existing shell scripts and automation workflows.
