history

Project history and usage

jello is a command-line JSON and JSON Lines filter that uses Python expressions instead of jq's filter language. The README describes it as similar to jq, but with standard Python dict and list syntax.

Project history

Kelly Brazil introduced jello in March 2020 as part of a set of structured-data command-line tools that also included jc and jtbl. In the author blog post, Brazil explains that jq is useful but that Python list and dictionary syntax can be easier for deeply nested structures.

The project changelog records an initial release on March 24, 2020 and version 1.0.0 on April 1, 2020. Subsequent releases added raw output, line output, custom initialization, schema output, color controls, Windows fixes, dot notation, file input, query files, and raw-string ingestion.

Adoption history

jello spread through Python and OS package channels. The README documents installation through pip, OS repositories, Windows MSI packages, GitHub release binaries, and Homebrew, while the batch input records packages in Homebrew, Debian, Fedora, MacPorts, Nix, and Ubuntu.

How it is used

Users pipe JSON or JSON Lines into jello, where the parsed data is available as the underscore object. Queries can be Python expressions, comprehensions, loops, or code loaded from a query file, and output can be JSON, JSON Lines, bash-array-friendly lines, or a grep-able schema.

Why package nerds care

jello is package-nerd significant because it belongs to the post-jq wave of structured-text CLI tools: it keeps Unix pipes and JSON filters, but chooses the host language many operators already know. It pairs naturally with jc, which turns command output into JSON, and jtbl, which turns JSON back into terminal tables.

Timeline

  • 2020: Initial release 0.1.5 was recorded on March 24.
  • 2020: Author blog post introduced jello as a Python-syntax jq alternative on March 25.
  • 2020: Version 1.0.0 removed the need to assign the result to r.
  • 2021: Version 1.3.0 added dot notation and larger-data performance improvements.
  • 2023: Version 1.6.0 added direct JSON or JSON Lines file input and query files.
  • 2025: Version 1.6.1 added raw-string ingestion and richer runtime/query error information.
