ghc-ede

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.
