Local Installation of alphaMELTS

pyrolite can download and manage its own version of alphaMELTS (without any real ‘installation’, per-se), and use this for automation purposes.

from pyrolite.util.log import stream_log

from pyrolite_meltsutil.download import install_melts
from pyrolite_meltsutil.util.general import pyrolite_meltsutil_datafolder

Here we can do a conditonal install - only downloading alphamelts if it doesnt exist:

if not (pyrolite_meltsutil_datafolder(subfolder="localinstall")).exists():
    stream_log("pyrolite-meltsutil", level="INFO")  # logger for output info
    install_melts(local=True)  # install a copy of melts to pyrolite data folder

Warning

This ‘local install’ method still requires that you have Perl installed, as it uses the Perl run_alphamelts.command script. If you’re on Windows, you can use Strawberry Perl for this purpose.
