Q: Dasel vs jq: which is better for JSON manipulation?

Dasel is ideal for multi-format workflows since it supports JSON, YAML, TOML, etc., with a consistent syntax, while jq is specialized for JSON and has a larger ecosystem. If you only work with JSON, jq might be more familiar, but Dasel offers cross-format consistency.

Q: Can Dasel handle XML files with namespaces?

The README doesn't explicitly mention XML namespace support. While Dasel can parse basic XML, complex structures with namespaces might require preprocessing or could lead to parsing issues, so it's best tested for simpler XML use cases.

Q: How to update a nested value in a YAML configuration file with Dasel?

Use a command like `dasel -i yaml --root 'foo.bar = "newValue"' < config.yaml`. This modifies the value at the specified path and outputs the updated document, allowing for in-place edits in automation scripts.

Q: Is Dasel available as a Docker image for containerized environments?

The README doesn't provide a Docker image, but you can install Dasel via Go or use prebuilt binaries. For containers, you might need to build it manually using the Go install method or include the binary in your Dockerfile.

Q: How to recursively find all keys in a JSON file using Dasel?

Use the recursive descent operator: `dasel -i json '..keyName'`. This searches all nested objects and arrays for the specified key and returns a list of matching values, as shown in the basic usage examples for deep data traversal.

Question 1

How to convert a JSON file to YAML using Dasel?

Accepted Answer

Use the command `dasel -i json -o yaml < input.json`. Dasel reads the JSON input and outputs it in YAML format, making it easy to switch between configuration formats in scripts or pipelines without additional tools.
