Forth layer

• Description
  • Features:
• Install
• Key bindings

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")))
