Q: What's the difference between yj and yq for YAML processing?

yj specializes in format conversion with order preservation between YAML, TOML, JSON, and HCL, while yq is a more general YAML processor for querying and manipulation. yj is better for reliable conversions, whereas yq offers more flexible data extraction.

Q: Can yj handle HCL to TOML conversion?

Yes, yj supports converting HCL to TOML using the `-ct` flag, such as `yj -ct < config.hcl` to output TOML format while maintaining key order from the original HCL file.

Q: How to install yj on Windows?

Download the Windows binary from the GitHub releases page, then add it to your PATH. Alternatively, use the Docker image or package managers like Chocolatey if available, though Homebrew is primarily for macOS.

Q: Does yj preserve comments when converting between formats?

No, yj does not mention comment preservation in its features; it focuses on data structure and key order, so comments are typically lost during conversion, which might be a drawback for documented configs.

Q: yj or jq for JSON transformations?

Use yj for converting between formats like JSON to YAML with order preservation, while jq is better for filtering, mapping, and reducing JSON data. yj excels at format changes, and jq at data manipulation within a format.

Question 1

How to convert YAML to JSON with yj preserving key order?

Accepted Answer

Use the command `yj -yj < input.yaml` or pipe the input with `cat input.yaml | yj -yj`. For indented output, add the `-i` flag for JSON to improve readability.

Question 2

What's the difference between yj and yq for YAML processing?
