From 73c2ae43f08ca35cbb8f86ec7c2efc15ad8686b9 Mon Sep 17 00:00:00 2001 From: Antoine Eiche Date: Sat, 29 Sep 2018 09:42:11 +0200 Subject: Add --graphml option to the nix-store --query command This prints the references graph of the store paths in the graphML format [1]. The graphML format is supported by several graph tools such as the Python Networkx library or the Apache Thinkerpop project.
