Generate two different versions of the same image about metalsmith-sharp HOT 8 CLOSED

i added example code to the usage section in the readme :)

from metalsmith-sharp.

Got it done with this matcher: **/*(!(*@1x)).@(jpg|jpeg|png) and doing a second pass with Sharp, but it makes my build process duration jump from couple of seconds to over a minute.

Got the speed back by doing a little tweak, final matcher: **/*(!(*@1x.)+(jpg|jpeg|png)).

Maybe a similar example matcher should be in the docs? (or then I couldn't figure out the "proper" way to accomplish this)

edit: I guess one could also use the metalsmith-branch plugin to achieve this.

See the tests here, where I create multiple versions of one image:
https://github.com/axe312ger/metalsmith-sharp/blob/master/test/index.test.js#L168

Alternatively, you can tell the plugin NOT to move files in the first step, so you do another image manipulation different naming. But calling the plugin twice might extend the compile time.

By default, the image is moved, thats why you had to use such a complex matcher.

I had disabled moving, the problem was that I didn't know I can do this:

.use(sharp([{
        src: '**/*.@(jpg|png|jpeg)',
        namingPattern: '{dir}/{name}@1x.jpg',
        methods: [{
          name: 'resize',
          args: [768]
        }, {
          name: 'toFormat',
          args: [ 'jpeg' ]
        }],
        moveFile: false
      }, {
        src: '**/*.@(jpg|png|jpeg)',
        namingPattern: '{dir}/{name}@2x.jpg',
        methods: [{
          name: 'resize',
          args: [1536]
        }, {
          name: 'toFormat',
          args: [ 'jpeg' ]
        }],
        moveFile: false
      }]))

So, I would add a section to the docs explaining, that to achieve multiple versions of the same files you can give sharp an array of objects as parameter, instead of only an object.

yes, sure, this is a pretty new feature of the plugin, i missed it in the docs

Nice, that should clear things up!

Also, thanks for a great plugin :)
