Specs checker tool

This simple tool helps downloading and parsing ETH2 specs, to be later used for making sure that our reference comments match specs definitions precisely.

Updating the reference specs

See main.go for a list of files to be downloaded, currently:

var specDirs = map[string][]string{
	"specs/phase0": {
		"beacon-chain.md",
		"fork-choice.md",
		"validator.md",
		"weak-subjectivity.md",
	},
	"ssz": {
		"merkle-proofs.md",
	},
}

To download/update specs:

bazel run //tools/specs-checker download -- --dir=$PWD/tools/specs-checker/data

This will pull the files defined in specDirs, parse them (extract Python code snippets, discarding any other text), and save them to the folder from which bazel run //tools/specs-checker check will be able to embed.

Checking against the reference specs

To check whether reference comments have the matching version of Python specs:

bazel run //tools/specs-checker check -- --dir $PWD/beacon-chain
bazel run //tools/specs-checker check -- --dir $PWD/validator
bazel run //tools/specs-checker check -- --dir $PWD/shared

Or, to check the whole project:

bazel run //tools/specs-checker check -- --dir $PWD
