## Project history and usage

FMPP, the FreeMarker-based file PreProcessor, is a Java text preprocessing tool for generating websites, source code, configuration files, and other text from FreeMarker templates. It can be used as a Unix-style command-line tool, an Ant task, or an embedded Java API.

### Project history

The official homepage states that FMPP was mostly written in 2003 by a single author to automate work tasks, and that it later entered maintenance mode. The project predates Java generics and Maven-like dependency management, which helps explain its older Java packaging style.

FMPP's version history records a long 0.8 and 0.9 series. In 2014, version 0.9.15 moved source code from SourceForge to GitHub, changed the license to Apache License 2.0, and aligned copyright and contribution handling with FreeMarker. Version 0.9.16 followed in 2018 with newer FreeMarker defaults, JSON-loader improvements, and Java 5 as the minimum runtime.

### Adoption history

FMPP was used heavily according to its official homepage, especially for recursive directory processing and static generation tasks built around FreeMarker. Its adoption is rooted in Java-era build tooling: the official docs advertise command-line use, Ant integration, and embeddability rather than a modern plugin ecosystem.

### How it is used

Users point FMPP at a source tree and configuration file, expose data such as XML, CSV, JSON, Java properties, Ant properties, or custom Java data loaders, and render outputs through FreeMarker templates. Its documented use cases include static websites, source generation, and configuration-file generation.

### Why package nerds care

FMPP is significant as a preserved Java CLI from the pre-Maven mainstream era that still solves a narrow templating problem with very little ceremony. For package maintainers it combines a command-line executable, Ant task, embedded API, bundled documentation, and a dependency relationship with Apache FreeMarker.

### Timeline

- 2003: FMPP was mostly written to automate work tasks.
- 2006: The 0.9.11 release updated bundled FreeMarker and BeanShell dependencies.
- 2007: The project switched from CVS to SVN.
- 2014: Version 0.9.15 moved source code to GitHub and changed licensing to Apache License 2.0.
- 2018: Version 0.9.16 updated FreeMarker support and raised the minimum Java version to Java 5.
