// `config` - Store arbitrary configuration values here.

// `globs` - These ultimately end up in their respective `gulp.src`.
// - `globs.js` - Array of asset-builder JS dependency objects. Example:
//   ```
//   {type: 'js', name: 'main.js', globs: []}
//   ```
// - `globs.css` - Array of asset-builder CSS dependency objects. Example:
//   ```

//   ```
// - `globs.fonts` - Array of font path globs.

//   .pipe(gulp.dest(path.dist + 'styles'))
// ```

// ## Gulp tasks
// Run `gulp -T` for a task summary

// ### Wiredep
// `gulp wiredep` - Automatically inject Less and Sass Bower dependencies. See
// https://github.com/taptapship/wiredep
gulp.task('wiredep', function() {
  var wiredep = require('wiredep').stream;
  return gulp.src(project.css)

    .pipe(changed(path.source + 'styles', {
      hasChanged: changed.compareContents
    }))
    .pipe(gulp.dest(path.source + 'styles'));
});

// ### JSHint
// `gulp jshint` - Lints configuration JSON and project JS.
gulp.task('jshint', function() {
  return gulp.src([
    'bower.json', 'gulpfile.js'
  ].concat(project.js))
    .pipe(jshint())
    .pipe(jshint.reporter('jshint-stylish'))
    .pipe(gulpif(enabled.failJSHint, jshint.reporter('fail')));
});

// ### Styles
// `gulp styles` - Compiles, combines, and optimizes Bower CSS and project CSS.
// By default this task will only log a warning if a precompiler error is
// raised. If the `--production` flag is set: this task will fail outright.
gulp.task('styles', gulp.series('wiredep', processStyles));

// ### Scripts
// `gulp scripts` - Runs JSHint then compiles, combines, and optimizes Bower JS
// and project JS.
gulp.task('scripts', gulp.series('jshint', processScripts));

// ### Fonts
// `gulp fonts` - Grabs all the fonts and outputs them in a flattened directory
// structure. See: https://github.com/armed/gulp-flatten
gulp.task('fonts', function() {
  return gulp.src(globs.fonts)
    .pipe(flatten())
    .pipe(gulp.dest(path.dist + 'fonts'))
    .pipe(browserSync.stream());
});

// ### Images
// `gulp images` - Run lossless compression on all the images.
gulp.task('images', function() {
  return gulp.src(globs.images)
    .pipe(imagemin([
      imagemin.mozjpeg({progressive: true}),
      imagemin.gifsicle({interlaced: true}),
      imagemin.optipng({optimizationLevel: 5}),
      imagemin.svgo({plugins: [
        {removeUnknownsAndDefaults: false},
        {cleanupIDs: false}
      ]})
    ]))
    .pipe(gulp.dest(path.dist + 'images'))
    .pipe(browserSync.stream());
});

// ### Clean
// `gulp clean` - Deletes the build folder entirely.
gulp.task('clean', require('del').bind(null, [path.dist]));

// ### Watch
// `gulp watch` - Use BrowserSync to proxy your dev server and synchronize code
// changes across devices. Specify the hostname of your dev server at
// `manifest.config.devUrl`. When a modification is made to an asset, run the
// build step for that asset and inject the changes into the page.
// See: http://www.browsersync.io
gulp.task('watch', function() {
  browserSync.init({
    files: ['{lib,templates}/**/*.php', '*.php'],
    proxy: config.devUrl,
    snippetOptions: {
      whitelist: ['/wp-admin/admin-ajax.php'],
      blacklist: ['/wp-admin/**'],
    },
  });
  gulp.watch([path.source + 'styles/**/*'], gulp.series('styles'));
  gulp.watch([path.source + 'scripts/**/*'], gulp.series('jshint', 'scripts'));
  gulp.watch([path.source + 'fonts/**/*'], gulp.series('fonts'));
  gulp.watch([path.source + 'images/**/*'], gulp.series('images'));
  gulp.watch(['bower.json', 'assets/manifest.json'], gulp.series('build'));
});

// ### Build
// `gulp build` - Run all the build tasks but don't clean up beforehand.
// Generally you should be running `gulp` instead of `gulp build`.
gulp.task(
  'build',
  gulp.series('styles', 'scripts', gulp.parallel('fonts', 'images'))
);

// ### Gulp
// `gulp` - Run a complete build. To compile for production run `gulp --production`.
gulp.task('default', gulp.series('clean', 'build'));
