standalone build

[aeosynth]

i would like a standalone build of mdv, which doesn't require changing browser settings, or including polymer's entire platform.js

[rafaelw]

Thanks for the request. Dan, I haven't looked at the build system. How hard would it be to setup a build into the MDV repo that is just for MDV?

[dfreedm]

Not too hard. The build steps are a part of the platform repo already, so it should be pretty simple.

Looks like the concatenation for builds is specified here: https://github.com/Polymer/platform/blob/master/build.json

The way the gruntfile uses this is fairly straightforward, but I'm not sure which files you'd need to get a standalone build of ONLY MDV.

[
  "../WeakMap/weakmap.js",
  "../observe-js/src/observe.js",
  "build/if-poly.js",
  "../ShadowDOM/build.json",
  "src/patches-shadowdom-polyfill.js",
  "src/ShadowCSS.js",
  "build/else.js",
  "src/patches-shadowdom-native.js",
  "build/end-if.js",

"src/patches-mdv.js" seems to wire up the Object.observe polyfill, and I'm guessing you'd need the if-poly.js to end-if.js for Shadow DOM stuff. I'm guessing you could rip out most lines that points to a build.json (depending on whether you want polymer-expressions support (I do).

  "../WeakMap/weakmap.js",
  "../observe-js/src/observe.js",
  "build/if-poly.js",
  "../ShadowDOM/build.json",
  "src/patches-shadowdom-polyfill.js",
  "src/ShadowCSS.js",
  "build/else.js",
  "src/patches-shadowdom-native.js",
  "build/end-if.js",

  "src/lang.js",
  "src/dom.js",
  "src/template.js",
  "src/inspector.js",

  "../NodeBind/src/NodeBind.js",
  "../TemplateBinding/src/TemplateBinding.js",
  "../polymer-expressions/build.json",
  "src/patches-mdv.js",
  "src/microtask.js",
]

Biggest question I see is whether "src/*.js" are required. Might give it a shot. But if anybody knows for sure, would like to know.

I think the proper dependency list for an "MDV" build is

[
  "../observe-js/src/observe.js",
  "../NodeBind/src/NodeBind.js",
  "src/TemplateBinding.js"
  "../polymer-expressions/build.json"
]

This sort of thing should be defined as the build.json file in TemplateBinding itself (minus the polymer-expressions part).

@rafaelw Does this seem feasible?

[rafaelw]

I'm totally clueless about the build system. Seems reasonable to have a build in TemplateBinding that excludes polymer-expressions and a build in polymer-expressions which includes all of that plus polymer-expressions and esprima.

Dan, can you make that happen, or tell me what I need to do?

[dfreedm]

Yep, I can make that happen.
