~ $rho notes.org

A lightweight Emacs,
built around Org.

ρEmacs is a preconfigured GNU Emacs distribution for Windows. A sane default setup, a client-server launcher that starts in the background, and Org mode wired up end to end — wiki, roam and capture included.

Headline stars are drawn as ● ○ ■ by org‑bullets, on by default.

01what-it-is

Emacs targets everything, so out of the box it targets nothing in particular. ρEmacs picks a lane: a fast default configuration, a launcher that behaves like a normal Windows program, and Org mode set up as a real knowledge base instead of an empty outline.

Install it, point it at a home directory, and start capturing notes — there is no fifty-file init.el to assemble first. You can still fall back to a bare configuration and build your own if you'd rather.

02org mode

The tedious parts, already wired up.

org-wiki, org-roam and org-protocol capture are each a small project to configure by hand. ρEmacs ships them working, with sensible default locations.

Preconfigured
org-wiki ~/org/wiki A personal wiki in plain org files, linked to each other. Its clip.jar helper — and the Java runtime it needs — ships in the distribution, so pasting a screenshot into a page just works.
org-roam ~/org-roam Non-hierarchical notes, Zettelkasten-style, with backlinks and a precompiled SQLite backend — no local compiler needed to get it running.
capture ~/org/capture.org org-protocol is one checkbox in the installer. Pair it with the Org Capture browser extension and links or selections land straight in your notes.

03launcher

One command, three letters.

rho starts Emacs in server mode the first time, then quietly behaves like emacsclient on every call after that — so opening a file from the command line, a shortcut, or a file manager is always instant.

The home directory is not tied to your Windows profile: it can be a dedicated folder, a portable directory next to the install, or set per-launch with /HOME:path. Use rhoc when you want the same thing from a terminal that waits for the buffer to close.

cmd.exe
>rho notes.org
no server running → starting one, then opening the file
>rho todo.org
server already up → opened in under a second
>rho /HOME:d:/rho-home notes.org
runs against a different ρEmacs home directory
>rhoc todo.org
— opens in the terminal, exits when you close the buffer

04what's inside

Configured, not decided for you.

Everything below is on by default and easy to turn off — ρEmacs is a starting point, not a framework you have to work around.

Runs light

Hack typeface by default — fast font-lock, no lag on large files.

find, grep and aspell bundled, no separate install required.

MELPA is preconfigured for anything you want to add yourself.

A portable install is available if you don't want a system footprint.

Comes configured

ido, ibuffer, uniquify, save-place and desktop-save, switched on.

tabbar and org‑bullets for a buffer list and outline that read at a glance.

Spacemacs, Moe or Arjen themes offered by the installer to start from.

A single option installs with none of the above, if you'd rather configure it yourself.

Open a file.
That's the whole setup.
