gerber plotter

Work in progress.

A printed circuit board Gerber and drill file plotter. Implemented as a Node transform stream that plotter command objects (for example, those output by mcous/gerber-parser) and output PCB image objects.

how to

$ npm install gerber-plotter

var fs = require('fs')
var gerberParser = require('gerber-parser')
var gerberPlotter = require('gerber-plotter')

var parser = gerberParser()
var plotter = gerberPlotter()

plotter.on('warning', function(w) {
  console.warn('plotter warning at line ' + w.line + ': ' + w.message)
})

plotter.once('error', function(e) {
  console.error('plotter error: ' + e.message)
})

fs.createReadStream('/path/to/gerber/file.gbr', {encoding: 'utf8'})
  .pipe(parser)
  .pipe(plotter)
  .on('data', function(obj) {
    console.log(JSON.stringify(obj))
  })

To run in this module in the browser, it should be bundled with a tool like browserify or webpack.

developing and contributing

Tests are written in Mocha and run in Node and a variety of browsers with Zuul and Open Sauce. All PRs should be accompanied by unit tests, with ideally one feature / bugfix per PR. Code linting happens with ESLint automatically post-test.

Code is deployed on tags via TravisCI and code coverage is tracked with Coveralls.

build scripts

• $ npm run lint - lints code
• $ npm run test - runs Node unit tests
• $ npm run test:watch - runs unit tests and re-runs on changes
• $ npm run test:browser - runs tests in a local browser
• $ npm run test:sauce - runs tests in Sauce Labs on multiple browsers
  • Sauce Labs account required
  • Local .zuulrc required
• $ npm run ci - Script for CI server to run
  • Runs npm test and sends coverage report to Coveralls
  • If not a PR, runs browser tests in Sauce
  • Not designed to (and won't) run locally
