Helheim is a modular Emacs configuration framework that emulates Helix's selection-action modal editing with multiple cursors, combining it with the full Emacs ecosystem. It includes pre-configured modules for version control, IDE features, Org-mode knowledge management, and terminal integration, requiring Emacs 29.1 or later.
OrgWebAlchemy is a Guile Scheme library that parses Org-mode documents using Parsing Expression Grammars (PEGs) instead of regular expressions, converting them to an AST and rendering to HTML. The author explains why PEGs are superior to regex for handling complex Org syntax like nested lists, inline markup, and source blocks, and highlights the modularity that enables future exports to other formats.
