/**
|
||||
* Common logic to make it easy to run the polymer linter and deploy tool.
|
||||
*
|
||||
* The functions in this library are designed to make it easier to create
|
||||
* `build.dart` files. A `build.dart` file is a Dart script that can be invoked
|
||||
* from the command line, but that can also invoked automatically by the Dart
|
||||
* Editor whenever a file in your project changes or when selecting some menu
|
||||
* options, such as 'Reanalyze Sources'.
|
||||
*
|
||||
* To work correctly, place the `build.dart` in the root of your project (where
|
||||
* pubspec.yaml lives). The file must be named exactly `build.dart`.
|
||||
*
|
||||
* It's quite likely that in the near future `build.dart` will be replaced with
|
||||
* something else. For example, `pub deploy` will deal with deploying
|
||||
* applications automatically, and the Dart Editor might provide other
|
||||
* mechanisms to hook linters.
|
||||
*
|
||||
* There are three important functions exposed by this library [build], [lint],
|
||||
* and [deploy]. The following examples show common uses of these functions when
|
||||
* writing a `build.dart` file.
|
||||
*
|
||||
* **Example 1**: Uses build.dart to run the linter tool.
|
||||
*
|
||||
* import 'dart:io';
|
||||
* import 'package:polymer/builder.dart';
|
||||
*
|
||||
* main() {
|
||||
* lint();
|
||||
* }
|
||||
*
|
||||
* **Example 2**: Runs the linter and creates a deployable version of the app
|
||||
* every time.
|
||||
*
|
||||
* import 'dart:io';
|
||||
* import 'package:polymer/builder.dart';
|
||||
*
|
||||
* main() {
|
||||
* deploy(); // deploy also calls the linter internally.
|
||||
* }
|
||||
*
|
||||
* **Example 3**: Always run the linter, but conditionally build a deployable
|
||||
* version. See [parseOptions] for a description of options parsed automatically
|
||||
* by this helper library.
|
||||
*
|
||||
* import 'dart:io';
|
||||
* import 'package:polymer/builder.dart';
|
||||
*
|
||||
* main(args) {
|
||||
* var options = parseOptions(args);
|
||||
* if (options.forceDeploy) {
|
||||
* deploy();
|
||||
* } else {
|
||||
* lint();
|
||||
* }
|
||||
* }
|
||||
*
|
||||
* **Example 4**: Same as above, but uses [build] (which internally calls either
|
||||
* [lint] or [deploy]).
|
||||
*
|
||||
* import 'dart:io';
|
||||
* import 'package:polymer/builder.dart';
|
||||
*
|
||||
* main(args) {
|
||||
* build(options: parseOptions(args));
|
||||
* }
|
||||
*
|
||||
* **Example 5**: Like the previous example, but indicates to the linter and
|
||||
* deploy tool which files are actually used as entry point files. See the
|
||||
* documentation of [build] below for more details.
|
||||
*
|
||||
* import 'dart:io';
|
||||
* import 'package:polymer/builder.dart';
|
||||
*
|
||||
* main(args) {

||||
* build(entryPoints: ['web/index.html'], options: parseOptions(args));
