From 61855a4e7bbaeb26de5a73040d87c28944e76b13 Mon Sep 17 00:00:00 2001 From: Harald van Dijk Date: Sun, 3 Nov 2019 21:46:59 +0000 Subject: Fix progress bar when nix-prefetch-url is piped. The intent of the code was that if the window size cannot be determined, it would be treated as having the maximum possible size. Because of a missing assignment, it was actually treated as having a width of 0. The reason the width could not be determined was because it was obtained from stdout, not stderr, even though the printing was done to stderr. This commit addresses both issues.
