Hi all,
The following are the changes that I made earlier.... and changes worked
fine...
This patch is pushed to my branch wip-sahithi
But when I try executing it now I don't find its results.... not even
soft-port is getting called...
May I know the reason behind this....
---
Thanks!!
Sahithi

Hi Sahithi,
I checked out the “wip-sahithi” branch and ran this command in a
terminal (urxvt):
./pre-inst-env guix build --check --no-grafts hello
I do see colours for phase start and end notices, so the code is fine.
What terminal are you using? Did this not work for you before? What
has changed since?

Gnome terminal
It worked for me earlier as well, i tested the code by building the
hello package before sending the patch.
Unsure why it dint work, i did couple of changes and reverted back
thought. Seems i missed something out.
