var isBlank = require('./isBlank');
var isRegExp = require('./isRegExp');
var result = require('./result');An intentionally simple templating language. This function is used to swap out event names
when binding with mapEvents. Replaces instances of {value} given an object of properties.
If these values are absent, nothing is replaced
For example:
template('{foo}', { foo: 'bar' }) //=> 'bar'
template('{foo}') //=> '{foo}'
var isBlank = require('./isBlank');
var isRegExp = require('./isRegExp');
var result = require('./result');The template function will use this pattern to match values
var pattern = /(?:\{*)([^{}\n]+)(?:\}*)/g;
var template = function (string, pool) {Don’t match values if there’s nothing to replace
if (isBlank(pool)) {
return string;
}Otherwise replace all instances of {key} with the value
of the passed pool argument. If a key doesn’t exist, then
just return the whole match.
return string.replace(pattern, function(whole, capture) {
return result(pool, capture.trim(), whole);
});
};Expose the templating pattern so that it can be overriden
Object.defineProperty(template, 'pattern', {
get: function() {
return pattern;
},
set: function(newPattern) {
if (isRegExp(newPattern)) {
pattern = newPattern;
} else {
throw new TypeError('template.setPattern expects a regular expression');
}
}
});
module.exports = template;
