A metalsmith plugin that outputs the time elapsed between calls to it.
$ npm install metalsmith-timer
Pass the plugin to
var timer = require('metalsmith-timer'); metalsmith .use(timer("init")) .use(someLongPlugin()) .use(timer("post-long-plugin"));
Standard runs of your build script won't output anything, but adding
DEBUG=metalsmith-timer to the call will output timings based on the labels.
