About:
qp is a lightweight command-line utility for querying and manipulating NDJSON (Newline Delimited JSON) streams. It provides a simple, jq-like syntax to filter, project, and transform data without the overhead of a full scripting language. This makes it ideal for high-performance data processing pipelines where JSON is the primary data interchange format.

Key Features:

Fast stream processing for large NDJSON files
Simple, intuitive query syntax for filtering and projection
Zero dependencies for easy installation and portability
Composable with standard Unix tools like grep, awk, and sed

Use Cases:

Extracting specific fields from large API response logs for analysis
Filtering and transforming data streams in real-time ETL pipelines
Quickly inspecting and debugging JSON-based data structures from the command line

Alternatives:

jq – More powerful and feature-rich, but can be complex for simple queries and has a steeper learning curve.
jql – A modern alternative with a similar goal, often praised for its ergonomic query language.
