Welcome to the Mustache project for Tcl, written by Andreas Kupries.

It provides a set of five related Tcl packages for the parsing and rendering of mustache-style logic-less templates, plus an application for easy command-line access to the functionality.

For availability please read Mustache - How To Get The Sources.


mustache::context objects make use of data frame objects to hold the values they will hand to the mustache render command while it renders a template.

mustache::frame provides seven TclOO classes for holding scalar values of various types, sequences, and mappings, all suitable for working with the objects provided by the mustache::context package.

Note however that any command prefix supporting the Instance API below will be suitable for working with the same.

This is not necessarily true for custom context objects. Such may have their own API for working with typed values.

Class API

Instance API

Data frames are what the context uses as containers for typed values. It should be noted that it actually does not care about the specific type of a value, only about the behaviour it supports, which can be queried (See the methods nil? and iterable?).

Scalar Instance API

Scalar data frames provide more than just the generic API. These additional methods should only be used after a type check:

Mapping Instance API

Mapping data frames provide more than just the generic API. These additional methods should only be used after a type check:
