To set up a DIALS development environment you start off with an empty directory.

On Linux and MacOS you can then run

$ wget https://raw.githubusercontent.com/dials/dials/main/installer/bootstrap.py
$ python bootstrap.py

which will install a complete development environment into the directory conda_base and download, configure, and compile cctbx, DIALS, and xia2. You will find all the source code repositories in the modules directory.

Once built, you need to load the DIALS development environment by running

$ . dials

Activating an installer build

The constructor installers (built from construct.yaml) expose only the DIALS programs, so activating DIALS does not put all of the bundled conda environment on your PATH. After installing, activate DIALS for the current session with:

• Linux / macOS: . setpaths.sh
• Windows (cmd): setpaths.bat
• Windows (PowerShell): . .\setpaths.ps1

These scripts live in the installation directory.

On Windows the installer also adds a Launch DIALS environment entry to the Start menu, which opens a command window with DIALS already on PATH.
