How to install the athanor command line

Download athanor-windows-x64.exe, rename it athanor.exe, put it in a folder on your PATH, and run athanor --version. It is one file with nothing to install, and it works offline.

Windows 10 or 11

The athanor command line converts, names, checks and screens structures from a terminal. It runs the same engine as the Athanor app, so a file is read, named and written exactly as the app does it. It never uses the network.

Steps

  1. Download the Windows build: athanor-windows-x64.exe (about 2.4 MB). It is also in the download menu on athanor.arbastro.com, under Command-line tool (Windows).
  2. Rename it athanor.exe and move it to a folder of your own, such as C:\Tools.
  3. Add that folder to your PATH, so any terminal can find it: search the Start menu for Edit environment variables for your account, select Path, press Edit, then New, and type the folder.
  4. Open a new terminal and check it:
athanor --version
athanor 0.1.0
  1. Run athanor with no arguments to list every command.

Note

The file is not code-signed yet, so Windows SmartScreen may stop it the first time: choose More info, then Run anyway.

There is no build for Mac or Linux yet. On those, use the MCP server or the web app.
