fenv newline #8

jakob@thinkpad ~> fenv export PYTHON=python2

jakob@thinkpad ~> set -g -x PYTHON python2

Can the newline printed by fenv be removed? I use fenv to initialize the shell, so I get like 4 newlines every time. (I know I can pipe to /dev/null, but I don't think this is intended)

I tried very hard to suppress the extra line ending, but it's a side effect of how fish manages multiline strings stored in variables -- they are just lists, which to be restored needs to be used with printf "%s\n", thus causing zero-length outputs to be printed as new lines.

Ah I guess I won't be getting rid of the pipe then. Thanks for the fast response!

You are welcome. Let's keep the issue open as far as it exists. While we don't fix it the best approach is to redirect to /dev/null
