Neomacs aims to become the Emacs of trees. Currently, Neomacs is a usable Lisp IDE and keyboard-driven browser. Get started Prebuilt binary for x64 Linux: https://github.com/neomacs-project/ neomacs/releases/ Documentation: M-x manual. There is also an online version at https:/ /neomacs-project.github.io/doc/toc.html To build locally, make sure you have SBCL, quicklisp, and the Ultralisp dist (if you haven't done so, (ql-dist:install-dist "http:/ /dist.ultralisp.org/" :prompt nil)). Clone this repo and https:// github.com/ceramic/ceramic under ~/quicklisp/local-projects/. Then (ql:quickload "neomacs") and (neomacs:start). To build the terminal emulator (currently Linux only), clone https:// github.com/neomacs-project/3bst under ~/quicklisp/local-projects/ then (ql:quickload "neomacs/term"). Neomacs relies on Electron which has known permission issues on some Linux distros. Try the following workaround: 1. sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0 2. sudo sysctl kernel.unprivileged_userns_clone=1 3. sudo chown root electron/chrome-sandbox && sudo chmod 4755 electron/chrome-sandbox For prebuilt binary, run this under bin directory from uncompressing the archive. For quickloaded Neomacs, run this under ~/.ceramic. If you are troubleshooting some Neomacs bug, (neomacs:start nil) might be helpful. It turns off built-in debugger and stream redirections and hand it over to external IDE (e.g. SLIME).
