1. Description

This layer adds basic support for the Forth family of languages to spacemacs.

1.1. Features:

Syntax highlighting
Showing meaning of objects in context of the current Forth session.
Eval of entire files or regions in current Forth session.
Passing interactive commands to current Forth session.

2. Install

To use this configuration layer, add it to your ~/.spacemacs. You will need to add forth to the existing dotspacemacs-configuration-layers list in this file.

A local installation of Forth needs to be present as well. GNU Forth is commonly available on Unix systems via the package manager. To bypass the query when calling run-forth, the default Forth can be configured by setting the appropriate variable.

(setq-default dotspacemacs-configuration-layers
              '((forth :variables forth-executable "gforth")))
