Dasel V2

[TomWright]

Since the creation of dasel I have seen usage and interest grow, highlighting some challenges that are incredibly hard or even impossible to solve with the current implementation.

As a result I am actively working on dasel v2 under the v2-wip branch. Note that this branch isn't stable and may have breaking changes in the future. At this point in time it is working however and you can install and play with it using go install github.com/tomwright/dasel/cmd/dasel@v2-wip.

I am looking for feedback, suggestions and function proposals. Feel free to respond in this discussion.

Improvements

Data navigation

This change introduces a hugely simplified way of navigating data internally, removing the need to propagate data changes back up the chain and hugely simplifying code.

It also makes it possible to access parent nodes and metadata, something that was not feasible before.

Selectors

New selector parsing is based on functions.

Each function:

• Has a distinct name
• May have aliases/custom parsing
• Accepts optional arguments
• May return 0 or more results
