Package atessera.templ

package atessera.templ

Provides template-based source code generation using Apache Velocity.

This package transforms structured document descriptions (from atessera.json) into source files for external tools such as LaTeX, MetaPost, and GNUPlot. Each template class corresponds to a specific Velocity template (a .vm file) and exposes a fluent API for populating the template context.

Key classes

EngineFactory

Creates and caches VelocityEngine instances configured with StringResourceLoader so that templates can be supplied programmatically at runtime.

Base

Common base class for all templates. Wraps a VelocityContext and provides render and renderToStringList methods.

PublicationTemplate

Generates LaTeX source for a full publication (book, paper, thesis, etc.) using the publication.vm template.

PresentationTemplate

Generates LaTeX Beamer source for a presentation using the presentation.vm template.

MetapostTemplate

Generates MetaPost source for a figure using the metapost.vm template.

GNUPlotTemplate

Generates GNUPlot source for a chart using the gnuplot.vm template.

Typical usage

 // Prepare templates (normally loaded once)
 Map<String, List<String>> templates = Map.of(
     "publication.vm", List.of("... template content ...")
 );
 EngineFactory factory = new EngineFactory(templates);

 // Generate a publication
 PublicationTemplate publ = new PublicationTemplate(factory);
 publ.setHeader(content);
 publ.setSections(sections);
 List<String> latexSource = publ.renderToStringList();
