Moldable Emacs

This is an extension of Emacs aiming to enable Moldable Development. Or better still, aiming to make you a better story teller when you deal with code.

TODO: I will detail dependencies and more information in a later change.

Ah! This is a pretty alpha release: I have a plan for quite few changes ahead! So avoid to build upon this prototype for now!!

Installation

The suggested way to install this package is via use-package. This is my installation configuration:

(use-package moldable-emacs
  :init (if (f-directory-p "~/.emacs.d/lisp/moldable-emacs")
            (shell-command "cd ~/.emacs.d/lisp/moldable-emacs; git pull;")
          (shell-command "cd ~/.emacs.d/lisp/; git clone git@github.com:ag91/moldable-emacs.git"))
  :load-path "~/.emacs.d/lisp/moldable-emacs/"
  :bind (("C-c m m" . me-mold)
         ("C-c m f" . me-go-forward)
         ("C-c m b" . me-go-back)
         ("C-c m o" . me-open-at-point)
         ("C-c m d" . me-mold-docs)
         ("C-c m e a" . me-mold-add-last-example)
         )
  :config
  (require 'moldable-emacs)
  (add-to-list 'me-files-with-molds (concat (file-name-directory (symbol-file 'me-mold)) "molds/experiments.el")) ;; TODO this is relevant only if you have private molds
  (me-setup-molds))

If you are using Doom Emacs slightly modify this:

(use-package! moldable-emacs
  ...
  (me-setup-molds))
(add-load-path! "~/.emacs.d/lisp/moldable-emacs/molds")

I am working on making moldable-emacs itself explain which optional and external dependencies you may need for what, but it is still work in progress. For now an incomplete list from the top of my mind.

Emacs Dependencies

This package requires:

dash.el
s.el
async.el
thunk.el

Optionally:

emacs-tree-sitter.el
you can get more functionality if you install tree-sitter’s grammars as well.
esxml.el
code-compass.el
org-ql
… (check these via the mold “WhatMoldsCanIUse?”)

(Optional) External Dependencies

graph-cli
graphviz
imgclip
???
