gulp-amp-svg-merge

Gulp plugin for merging Amplience SVG metadata into SVG files

Installation

$ npm install --save svg-metadata-merge

Usage

var ampSvgMerge = require('gulp-amp-svg-merge');

gulp.src('svg/*.svg')
    .pipe(ampSvgMerge({
      svgDir: './svg',
      subsFileExt: '.metadata',
      headerFileExt: '.header'
    }))
    .pipe(gulp.dest('svg/merged'));

Options

svgDir - location of the metadata and header files.

subsFileExt - file extension to identify the metadata substitutions file.

headerFileExt - file extension to identify the header attributes file.

The metadata and header files much have the same filename as the target SVG (plus the additional file extension identifier).

Example SVG

These examples are a guide to what should be provided to the module and what the expected output will be.

Input SVG

The input file should be a valid SVG file like this:

<svg version="1.1" xmlns:svg="http://www.w3.org/2000/svg"
   xmlns:ampsvg="http://media.amplience.com/2016/svg-extensions"
   xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="200px"
	 height="200px" viewBox="0 0 200 200" enable-background="new 0 0 200 200" xml:space="preserve">

  <metadata>
  </metadata>
  <polygon points="19,6.4 17.6,5 12,10.6 6.4,5 5,6.4 10.6,12 5,17.6 6.4,19 12,13.4 17.6,19 19,17.6 13.4,12"/>
</svg>

Or if there is existing metadata:

<svg version="1.1" xmlns:svg="http://www.w3.org/2000/svg"  xmlns:ampsvg="http://media.amplience.com/2016/svg-extensions"
   xmlns:nonamp="http://media.amplience.com/2016/svg-extensions"
   xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="200px"
	 height="200px" viewBox="0 0 200 200" enable-background="new 0 0 200 200" xml:space="preserve">

  <metadata>
    <nonamp:stuff>
      <nonamp:substitutions type="test-type" value="I am a test">
      </nonamp:substitutions>
    </nonamp:stuff>
  </metadata>
  <polygon points="19,6.4 17.6,5 12,10.6 6.4,5 5,6.4 10.6,12 5,17.6 6.4,19 12,13.4 17.6,19 19,17.6 13.4,12"/>
</svg>

Metadata

A metadata file can be created to merge in Amplience specific metadata. The contents of the metadata file should look like this:

<ampsvg:metadata>
    <ampsvg:substitutions>
        <ampsvg:substitute type="set-innerText" target="//svg:text[@id='text01']" value="10% off" />
    </ampsvg:substitutions>
    <ampsvg:fonts>
        <ampsvg:font font-family="/playground/Roboto" />
    </ampsvg:fonts>
</ampsvg:metadata>

Note: <metadata> should not be included in this file.

Headers

A header file can be created to merge in svg element attributes. Th file should contain:

<svg xmlns:svg="http://www.w3.org/2000/svg" xmlns:ampsvg="http://media.amplience.com/2016/svg-extensions" width="200px" height="200px" viewBox="0 0 200 200"></svg>
