Shell-like interface to devicetree

Author:

Chris Duf

dtsh is an interactive shell-like interface with a devicetree and its bindings:

• browse the devicetree through a familiar hierarchical file-system metaphor

• retrieve nodes and bindings with accustomed command names and command line syntax

• generate simple documentation artifacts by redirecting commands output to files (text, HTML, SVG)

• common command line interface paradigms (auto-completion, history) and keybindings

$ dtsh build/gzephyr/zephyr.dts

This software was created as a Proof of Concept for a simple tool that could assist newcomers to Zephyr in understanding what a devicetree is, and how bindings describe and constrain its content.
