Neomacs aims to become the Emacs of trees. Currently, Neomacs\nis a usable Lisp IDE and keyboard-driven browser.\n\n# Get started\n\nPrebuilt binary for x64 Linux: https://github.com/neomacs-project/neomacs/releases/\n\nDocumentation: `M-x manual`. There is also an online version at https://neomacs-project.github.io/doc/\n\nTo 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)`.\n\nTo build the terminal emulator (currently Linux only), clone `https://github.com/neomacs-project/3bst` under `~/quicklisp/local-projects/` then `(ql:quickload \"neomacs/term\")`.\n\nNeomacs relies on Electron which has known permission issues on some Linux distros. Try the following workaround:\n\n1. `sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0`\n2. `sudo sysctl kernel.unprivileged_userns_clone=1`\n3. `sudo chown root electron/chrome-sandbox \u0026\u0026 sudo chmod 4755 electron/chrome-sandbox` For prebuilt binary, run this under `bin` directory from uncompressing the archive. For `quickload`ed Neomacs, run this under `~/.ceramic`.\n\nIf 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).\n\n# Screenshots\n\n![Neomacs](demo.png)\n\nTwo built-in themes, accessible via `M-x apply-theme`:\n![Neomacs](matrix.png)\n![Neomacs](anti-matrix.png)\n\n# Contributing\n\nIf you have any question, suggestions, ideas, crazy or not, feel free\nto post them in the issues or discussions! If you have a patch, don't\nhesitate to open a PR!
