README.md

We feel like it's time to clean up some more technical debt in spritesmith. Here are the tasks we want to take care of:

Phase 1 - Clean up distractions 🚿

  • Add foundry
  • Update all package.json to use node>=0.10.0
  • Update all Travis CI to use node>=0.10.0
    • grunt-spritesmith
    • gulp.spritesmith
    • spritesmith
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
  • Add deprecation notice to pngsmith and remove it from any READMEs

Phase 1.5 - Clean up code-based distractions 📝

  • Add twolfson-style to each part of our system
    • grunt-spritesmith
    • gulp.spritesmith
    • spritesmith
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
  • Clean up technical debt (e.g. sloppy exec, undesired sync calls, usage of shell-quote)
  • Get rid of exporters logic -- it is unnecessary -_-;;
    • grunt-spritesmith
    • gulp.spritesmith
    • spritesmith
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
  • Evaluate and clean up READMEs
    • grunt-spritesmith
    • gulp.spritesmith
    • spritesmith
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
  • Go back and fix up spritesmith-engine-test as well -_-;;
    • foundry
    • twolfson-style
    • README
    • Travis CI/node version?
    • Maybe break down jpeg and png tests into their own sets?
    • Also pull over gif tests from pixelsmith?
    • Break up repo into -spec and -test repos (don't forget to release -spec)
  • Document -spec in all READMEs
    • grunt-spritesmith
    • gulp.spritesmith
    • spritesmith
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
  • Add newsletter to spritesmith family

Phase 1.6 - Add spec assertion to spritesmith 🎱

  • Add specVersion assertion to -test repo
  • Add specVersion/upgrade -test to each engine in patch release
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
  • Add specVersion assertion to spritesmith in minor release
  • Upgrade to latest spritesmith in grunt-/gulp.
  • Document spritesmith-engine keyword in -spec
  • Add spritesmith-engine to all engines
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith

Phase 2.0a - Update spec to be less hackish around engine settings ♻️

  • Update -spec to use constructor for Engine (and maybe Canvas)
  • Transition engines to using new -spec variation
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
    • -test
    • spritesmith
  • Update documentation on engines to state new spec version
    • grunt-spritesmith
    • gulp.spritesmith
    • spritesmith
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
    • -spec
    • -test

Phase 2.0b - Add streaming output ✨

  • Move all spritesmith engine to use stream as output
    • Allows for faster writes to disk
    • Gets off of our original binary string hack
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
    • -spec
    • -test
    • spritesmith (move to buffer only via concat-stream for now -- see 2.1 for future notes)
    • gulp.
    • grunt-

Phase 2.0c - Add vinyl as input 🔨

  • Update all engines to accept either filepath or vinyl
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
    • -spec
    • -test
    • spritesmith (need to see how cross/compatible we can handle paths vs vinyl)
    • gulp. (move to always pass vinyl through)
    • grunt- (always pass through filepaths -- can't make assumptions about content as received on other side -- maybe we could always do null?)
  • Document in each engine's README about what they support from vinyl (e.g. require filepath vs choose filepath, buffer, or stream)
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
    • spritesmith
    • gulp. (document read: false?)
    • grunt-
  • Add console.warn to each engine when we encounter a vinyl file with extra buffer/stream when we only need filepath
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
  • Build spritesmith-engine-base or spritesmith-engine-util repo (prob the latter) so we can get format coercion for jpg and get grunt- passing
    • Wound up using vinyl-file and one-offs for each engine but have unifying test
  • Update -spec with note about -base/-util
  • Probably re-use spritesmith-engine-util for String -> vinyl coercion but need to see if spritesmith needs raw names or notes
    • Be sure to use options provided by engine (e.g. buffer: null)
    • Wound up using vinyl-file

Phase 2.0d - Ship all the things :shipit:

  • Remove git+ssh URLs from all repos (I think only spritesmith had these)
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
    • -spec
    • -test
    • spritesmith
    • gulp.
    • grunt-
  • Remove all TODOs
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
    • -spec
    • -test
    • spritesmith
    • gulp.
    • grunt-
  • Review diffs of all repos
    • pixelsmith
    • gmsmith
    • phantomjssmith
    • canvassmith
    • -spec
    • -test
    • spritesmith
    • gulp.
    • grunt-
  • Document breaking changes in grunt-, gulp., and spritesmith
    • spritesmith is buffer callback (not binary string)
    • gulp. people should be aware of buffer: null or whatever the syntax is
    • All should have "Upgrade to v2 spec" as a major heading
  • Publish -spec and -test
  • Upgrade -test in each of the engines and verify Travis CI passes
  • Publish engines
  • Upgrade engines in spritesmith and publish
  • Upgrade spritesmith in grunt- and gulp. and publish

Phase 2.1 - Update spritesmith to leverage streams ▶️

  • To properly leverage streams, we are going to need to either: break down spritesmith into reusable parts or move the retina logic into spritesmith (leaning towards the latter)
  • Without streams, we will have a chance of opening a disk stream without knowing if retina images properly correlate
  • Move to returning object with streams on it
    • spritesmith
    • gulp.
    • grunt-
  • Ship all the libraries

Bonus

  • Define a keyword for spritesmith-engine and document it
  • Relocate engineOpts from a singleton pattern to part of the engine constructor
    • Actually, that's terrible for instanceof and what not -- Maybe expose gmsmith.gm and gmsmith.im with gmsmith being same but autoinvokes the right one
  • Remove png fallback from all engines
    • Deciding not to since it complicates logic in spritesmith
  • If we create a util repo, then maybe define default format there?
    • We have decided to not create this repo for now
  • Remove exporters coercion from all engines -- we should define only jpeg, gif, and png in our specification and perform normalization within spritesmith
    • We have chosen to allow jpg as a one-off in each repo for now
  • Update save-pixels to use latest release with options.quality support
    • Deferring for now -- almost burned out on spritesmith
  • Close twolfson/gulp.spritesmith#53
