Forth layer

Description

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

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.

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")))
