How to Change the Default Delimiter Of Mustache.js?

To change the default delimiter of Mustache.js, you can use the Mustache.tags property. By default, Mustache.js uses {{ and }} as delimiters for variables and sections. To change these delimiters, you can set the Mustache.tags property to an array containing the new opening and closing delimiters. For example, if you want to use [[ and ]] as delimiters, you can set Mustache.tags to ['[[', ']]']. This will change the default delimiters used by Mustache.js throughout your templates.

What characters can be used as delimiters in mustache.js?

The characters that can be used as delimiters in mustache.js are:

1. {{ }} - Double curly braces
2. [[[ ]]] - Triple square brackets
3. {{= =}} - Custom delimiters specified by the user

What is the purpose of changing the default delimiter in mustache.js?

Changing the default delimiter in mustache.js allows for customization and flexibility in using the template engine. By changing the delimiter, developers can avoid conflicts with other templating engines or programming languages that use the same default delimiters. It can also help improve the readability and maintainability of the templates by selecting delimiters that are more meaningful or relevant to the specific use case.

How do I specify a different delimiter in mustache.js?

In mustache.js, you can specify a different delimiter by using the Mustache.tags object. By default, mustache.js uses {{ and }} as delimiters for placeholders. However, you can change these delimiters by setting the Mustache.tags object to a new set of delimiters.

Here's an example of how to specify a different delimiter in mustache.js:

1
2
3
4
5

Mustache.tags = ['<%', '%>'];
var template = '<% name %> is <% age %> years old.';
var data = {name: 'John', age: 30};
var output = Mustache.render(template, data);
console.log(output); // Output: 'John is 30 years old.'

In this example, we set the delimiters to <% and %>, and then we use them in the template to define placeholders for the name and age values from the data object.

By changing the Mustache.tags object, you can specify different delimiters for your mustache.js templates to avoid conflicts with other templating systems or to better fit your project's needs.

How to change the default delimiter in mustache.js without affecting existing templates?

In mustache.js, if you want to change the default delimiter without affecting existing templates, you can use the Mustache.parse function to pre-parse the template with the new delimiter.

Here's an example of how you could change the default delimiter from {{ to <% and %>:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14

// Create a new Mustache instance with custom delimiters
var customMustache = new Mustache();
customMustache.tags = ['<%', '%>'];

// Example template with the new delimiters
var template = '<% name %> is <%age%> years old';

// Pre-parse the template with the new delimiters
var parsedTemplate = customMustache.parse(template);

// Render the parsed template with data
var output = customMustache.render(parsedTemplate, { name: "John", age: 30 });

console.log(output); // Output: John is 30 years old

By using this approach, you can change the default delimiter without affecting existing templates, as the Mustache.parse function allows you to specify custom delimiters for a specific template.
