tera

The tera package uses extendr to provide access to Vincent Prouillet’s Tera templating engine in Rust. Users mainly interact with a Tera R6 object, which serves as a template library with encapsulated methods for rendering templates with a given context. Template syntax supports additional logic, including built-in filters, tests, and functions, as well as loops, conditions, and inheritance. Documentation for Tera’s templating syntax can be found at https://keats.github.io/tera/.

Installation

)
#> [1] "<p>Hello world. This is tera.</p>"
