Improve gulp plugin adapters (many plugins don't work, many aren't supported).

[unlight]

gulp-eslint do empty output.
Check example: https://www.npmjs.com/package/gulp-eslint
In gulp I must use eslint.format(), but how to inject it to sigh file?

var eslint; // wrapped
var gEslint = require('gulp-eslint');

module.exports = function(pipelines) {
  pipelines['lint'] = [
    glob('src/*.js'),
    eslint(),
   // gEslint.format() // does not work
  ];
}

Some plugins cannot be injected because without gulp- prefix they are reserved words:
gulp-if, gulp-switch, etc.

Good point, I will add gulpPluginName as an alternative, or maybe gulp.pluginName. Currently gulp plugins that export stream manipulators as subfields aren't supported but adding such support shouldn't be that difficult, you can raise a github issue for it if you want?

Some more info about gulp-plugins.

Some plugins are not following gulp-plugin name conventions.
http://npmsearch.com/?q=keywords:gulpfriendly
So it is not possible to inject it.

I made some research, and some gulp-plugins does not work.
Some of them fails silently (does not output pipeline x complete: 0.023 seconds)

List of gulp plugins that works:

• gulp-debug
• gulp-ng-annotate
• gulp-bump
• gulp-notify
• gulp-benchmark
• gulp-less (extension stays as less)

List of gulp plugins that does not work:

• gulp-rename
• gulp-duration
• gulp-size
• gulp-eslint (sigh cannot adapt exported properties from module)
• gulp-browatchify (fails silently)

Thanks for the information.

• gulp-browatchify: most of my integration work with sigh will be aimed at jspm rather than browserify as I strongly believe jspm is the future.
• gulp-rename: this adapts the streamed value to a differing path value, this wouldn't be compatible with sigh's adapter. It could be made to work though with a new feature to the gulp adapter code.

That's sad. Browserify has a lot of useful plugins.

gulp-typescript doesnt work.

Could you elaborate on this? Also would renaming be supported by the built-in plugins or would that need to be done in a new plugin (I'll probably give that a shot to learn more)?

Ah it's because the way that gulp determines which output event relates to which input event is by checking the filenames... if a filename changes then it fails. However gulp allows you to attach your own metadata to each event (which well behaving plugins are supposed to pass through) which could be used instead. Should be a very simple fix, if you open a bug for it I can tackle it as soon as I'm back from holiday.

Hm that's not it, not sure why it isn't working.
