Apache Texen

Apache Texen is a text and code generation tool (template-based code generation) built on the Apache Velocity templating engine for automating file creation from templates and data.

• Template-driven generation of text and source code files (code generation)
• Leverages Apache Velocity as the underlying templating engine (templating framework)
• Command-line style tool for executing templates against data to produce output artifacts (build and scaffolding automation)
• Supports configuration-driven control of input templates, output locations, and generation parameters (configuration-based tooling)
• Integrates into build and development workflows for repeatable artifact generation (software development tooling)

More About Apache Texen

Apache Texen is a template-based text generation utility (code generation) that uses the Apache Velocity engine to produce files such as source code, configuration, or documentation from predefined templates and structured data. It operates as part of the Apache Velocity subproject portfolio under The Apache Software Foundation and relies on Velocity’s templating language and runtime for its core processing model.

The project targets scenarios where teams need repeatable, scripted generation of text artifacts from templates (software development tooling). Typical uses include generating boilerplate source code, configuration files, or project scaffolding from a consistent template set. Texen runs templates against input data contexts, applying Velocity syntax for variable substitution, control flow, and iteration, and writes the rendered results to files in a specified output directory.

Texen builds directly on the Velocity templating engine (templating framework), so it uses the same Velocity Template Language for placeholders, directives, and macros. Enterprises that already use Velocity in web or service layers can reuse Velocity skills and template assets when adopting Texen for offline generation tasks. The tool consumes configuration that defines which templates to run, where to locate them, which data sources or context objects to expose, and how to route generated content to output paths.

In enterprise environments, Texen can integrate into build systems or scripted automation pipelines (build and release engineering). It can participate in generation steps for code skeletons, interface stubs, configuration bundles, or documentation snapshots. Because the output is plain text, Texen can target multiple languages and platforms, as long as the structure can be described with templates.

From an architectural perspective, Texen functions as a thin layer around Velocity (templating framework), adding tooling conventions for batch generation and file management. It sits in the application development tooling category, adjacent to code generators and scaffolding tools, and is suitable where teams want to centralize template logic while keeping the rendering runtime decoupled from application execution.

For directory and taxonomy purposes, Apache Texen can be classified under template-based code and text generation tools, leveraging a general-purpose templating engine to automate file creation within software development and build workflows.
