Templating language with similar syntax and features to Liquid or Jinja2
ED-E is a templating language written in Haskell with a specific set of features: * Logicless within reason. A small set of consistent predicates and expressions for formatting and presentational logic are provided. * Secure. No arbitrary code evaluation, with input data required to be fully specified at render time. * Stateless. Parsing and rendering are separate steps so that loading, parsing, include resolution, and embedding of the compiled template can optionally be done ahead of time, amortising cost. * Markup agnostic. ED-E is used to write out everything from configuration files for system services, to HTML and formatted emails. * Control over purity. Users can choose pure or IO-based resolution of 'include' expressions. * No surprises. All parsing, type assurances, and rendering steps report helpful error messages with line/column metadata. Variable shadowing, unprintable expressions, implicit type coercion, and unbound variable access are all treated as errors.
