Usage

The static renderInline method takes a Mustache template of type String and a model of type Map or Object and returns the rendered template as a String.

varmodel = newMap.of("name","TERMplates");
System.out.println(Termplates.renderInline("Hello {{name}}!", model));

Colors can be accessed by using the {{term}} namespace.

System.out.println(Termplates.renderInline("Hello {{#term.red}}{{name}}{{/term.red}}", Map.of("name", "TERMplates")));

Colors and text decorations can be combined by nesting them (for a full list of supported escape sequences, see ANSI Escape Codes. ).

System.out.println(Termplates.renderInline("Hello {{#term.bold}}{{#term.red}}{{name}}{{/term.red}}{{term.bold}}", Map.of("name", "TERMplates")));

For rendering more complex templates, create a file ending on .mustache under src/main/resources/templates, e.g. movies.mustache.

{{#term.underline}}MOVIES{{/term.underline}}{{! iterates over the `movies` array and renders each element on its own line }}{{#movies}}{{.}}{{/movies}}

Use the static renderFile method to render the file containing the method.

// note that you reference the file only by its prefix, i.e. "movies", not "movies.mustache"System.out.println(renderFile("movies", Map.of("movies", List.of("Evil Dead", "Evil Dead 2", "Army Of Darkness"))));
