python-grace

An unofficial Python wrapper for the GRACE system (the public version for tree-level computations).

This is a pre-alpha version.

Requirements

• Python >= 3.6.1
• pip >= 19.0
• C compiler
• Fortran compiler
• Make utility
• X Window system (optional, for gracefig and grcdraw)
• Motif Toolkit or its clone (optional, for gracefig)
• ps2pdf in Ghostscript (optional, to generate PDF files with gracefig)

Debian or Ubuntu

sudo apt-get install gfortran ghostscript libmotif-dev make python3-pip

Fedora

sudo dnf install gcc-gfortran ghostscript make motif-devel python3-pip

Installation

Use pip:

pip install python-grace

which installs the grace command. (You may need to adjust $PATH. You can always use python -m grace, instead.)

To select the compilers, specify them as environment variables when pip runs:

CC=gcc-12 FC=gfortran-12 pip install python-grace

You can use pipx instead of pip if you prefer to install this software in an isolated and/or temporary environment.

Example

mkdir my_process
cd my_process
grace template sm/eewwa
grace grc
grace gracefig - # requires optional dependencies
grace grcfort
make all
./gauge
./integ
./spring

Development

poetry install
poetry run task prepare
