VM File Extension

Velocity Template – file format by Apache

VM is a file extension associated with Velocity Template, a Java-based template engine developed by Apache. It is used to generate dynamic web content, emails, and other documents by combining data with templates written in a simple markup language.

Definition of a VM File

A VM file is a text file that contains Velocity Template Language (VTL) code. VTL is a template language used to generate dynamic web content, such as HTML pages. VM files are typically used to create web pages that are dynamically generated based on data from a database or other source.

How VM Files Work

VM files are processed by a Velocity engine. The Velocity engine reads the VM file and parses the VTL code. The VTL code is then used to generate a dynamic web page. The generated web page can then be displayed in a web browser.

VM files are often used to create web pages that are personalized for each user. For example, a VM file could be used to create a web page that displays a user’s name and account information. The VM file would use VTL code to access the user’s data from a database and then generate a web page that is customized for the user.

Opening VM Files

VM files, or Velocity Template files, are associated with the Apache Velocity engine, a widely-used Java-based template engine. These files contain templates for generating dynamic content, such as web pages, emails, or documents. To open a VM file, you will need a text editor or an integrated development environment (IDE) with support for Velocity templates.

Using a Text Editor

You can open a VM file using any plain text editor, such as Notepad (Windows), TextEdit (macOS), or gedit (Linux). However, text editors do not provide any syntax highlighting or code completion for Velocity templates, making it harder to read and edit the code.

Using an IDE

For enhanced functionality and ease of use, you can use an IDE that supports Velocity templates. Popular IDEs like Eclipse, IntelliJ IDEA, and NetBeans provide dedicated support for Velocity, including syntax highlighting, code completion, error detection, and debugging capabilities. This makes it much easier to develop and maintain Velocity templates.

Velocity Template Language (VTL)

Velocity Template Language (VTL) is a powerful templating language designed specifically for generating text-based content in Java applications. It is an open-source project developed by the Apache Software Foundation. VTL is widely used in web development, content management systems, and other applications that require dynamic content generation.

VTL templates are written in a simple, easy-to-read syntax that allows developers to define the structure and content of the generated text. Velocity templates can be used to create a wide range of content, including HTML, XML, plain text, and even code. Velocity provides a rich set of built-in functions and directives that enable developers to control the flow of the template execution, access data objects, and perform various transformations on the generated text.
