Introduction

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 errors.

Please see the documentation for more information.

Syntax

A set of syntatic/semantic fragments for all supported expressions can be found in the [tests](test/resources) or the documentation.
