Node API

const lookmlParser = require('lookml-parser')

lookmlParser.parse("view: foo{}")
lookmlParser.parseFiles({
		source:  "*.{view,model,explore}.lkml",
		fileOutput: "by-type" // or "array" or "by-name". "by-name" is recommended. 
		transformations: {},	
		globOptions: {},
		readFileOptions: {encoding:"utf-8"},
		readFileConcurrency: 4,
		console: console
	})

Output & Features

At the moment, parseFiles outputs a collection of files, each with their own parsed contents, as well as models resulting from following includes from model files.

The collection of files is an object by default, keyed by type, then by name, but can be requested as either an array or an object keyed by the name of the file including type.

Conditional Comments

If you want to leverage LookML syntax to embed arbitrary other markup/objects that would be rejected by the native IDE, the CLI and parseFiles function now allow this with conditional comments:

view: foo {
	# PARSE-ME!
	# owner: "Fabio"
	# version: {major:1 minor:4 date:"2018-01-01"}
	dimension: bar {}
}

> lookml-parser --conditional-comment="PARSE-ME!"

Project Imports

The parseFiles method and CLI will resolve any include statements of the style "//project_foo/..." as "/imported_projects/project_foo/...". Therefore, the parser supports project imports, assuming you have previously copied/cloned the remote project to the appropriate location ahead of invoking the parser.

LookML Dashboard support

Since LookML Dashboards are actually YAML, lookml-parser does not handle parsing them. However, this module accepts js-yaml as an optional dependency. If you install js-yaml, lookml-parser will use it to parse LookML dashboards and will the dashboards them into any including models. To use this functionality, make sure to specify an input argument, as the default input pattern does not include dashboard files.

npm install -g lookml-parser
npm install -g js-yaml
lookml-parser --interactive --file-output=by-name --input="{*.,}{manifest,model,view,explore,dashboard}.{lkml,lookml}"
