feelers

FEELers is a string templating library built on top of DMN FEEL (Friendly Enough Expression Language), similar to Mustache or Handlebars. Version 1.5.1 (stable) is maintained under the bpmn-io organization. It provides a Lezer grammar/parser, a CodeMirror editor integration, and an interpreter using the feelin engine. Key differentiators: uses FEEL expressions for logic, supports conditionals (#if), loops (#loop), and variable inserts ({{}}).
