chimerax.el -- The ChimeraX command line in Emacs

chimerax.el

This package provides a REPL that uses the ChimeraX REST server to allow you to send commands to ChimeraX from Emacs. Mostly a hatchet job on dap-ui-repl code.

Setup

In ChimeraX, open the Preferences panel and click on the startup tab. Configure ChimeraX to start its REST server at the same port every time and to return results in JSON.

remotecontrol rest start port 3000 json true

In Emacs, set chimerax-rest-url to the URL this command returns. For example, if the output is

REST server started on host 127.0.0.1 port 3000
Visit http://127.0.0.1:3000/cmdline.html for CLI interface

then in your init.el:

(setq chimerax-rest-url "http://127.0.0.1:3000")

Usage

M-x chimerax-repl will open a buffer at the bottom of the Emacs window that takes commands and forwards them to ChimeraX. The results of ChimeraX commands will be printed as in the example below:
