The same as <?=global.function()?>, where 'global' can be redefined by EJS object option 'global_id'.
This construction useful then you pass a some object to EJS function like...
var Ejs = require('nano-ejs'),
nc = require('nano-color');
var css_helpers = {
hsv2hrgb: function (h,s,v) {
return nc.rgb2hex(nc.hsv2rgb(h,s,v));
}
};
var css_text = '\
.error { color: <?.hsv2hrgb(0, 1, 1)?>; }\n\
.warning { color: <?.hsv2hrgb(120, 1, 1)?>; }\n\
';
var ejs_fn = Ejs.compile(css_text, 'css_helpers', { global_id: 'css_helpers' });
console.log(ejs_fn(css_helpers));console output:
.error { color: #FF0000; }
.warning { color: #00FF00; }API
