LSIF development and testing utilities

Install

Assumes a working Go installation:

# lsif-validate
go get github.com/sourcegraph/lsif-test/cmd/lsif-validate

# lsif-visualize
go get github.com/sourcegraph/lsif-test/cmd/lsif-visualize

Resulting binary should then be in your $GOPATH/bin (conventionally $HOME/go/bin), so make sure thats in your $PATH or else invoke using absolute/relative location.

Binary releases coming soon™️

lsif-validate

This command validates the output of an LSIF indexer. The following properties are validated:

• Element IDs are unique

• All references of element occur after its definition

• A single metadata vertex exists and is the firsts element in the dump

• The project root is a valid URL

• Each document URI is a URL relative to the project root

• Each range vertex has sane bounds (non-negative line/character values and the ending position occurs strictly after the starting position)

• 1-to-n edges have a non-empty inVs array

• Edges refer to identifiers attached to the correct element type, as follows:

  label	inV(s)	outV	condition
  contains	range		if outV is a document
  item	range
  item	referenceResult		if outV is a referenceResult
  next	resultSet	range/resultSet
  textDocument/definition	definitionResult	range/resultSet
  textDocument/references	referenceResult	range/resultSet
  textDocument/hover	hoverResult	range/resultSet
  moniker	moniker	range/resultSet
  nextMoniker	moniker	moniker
  packageInformation	packageInformation	moniker

• Each vertex is reachable from a range or document vertex (ignored: metadata, project, document, and event vertices)

• Each range belongs to a unique document

• No two ranges belonging to the same document improperly overlap

• The inVs of each item edge belong to that document referred to by the edge's document field
