* 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.

#+BEGIN_SRC emacs-lisp
|

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