Subject: Re: Can we increase the print width/column in daemon backtraces

Hi,

Pierre Neidhardt <mail@ambrevar.xyz> skribis:

I understand, but which backtraces are we talking about?

COLUMNS only helps if you wish to debug ‘guix build’ itself.  It cannot
influence Guile processes launched by the daemon, such as those that
build derivations and the helper processes (‘guix substitute’, etc.).

In most cases, we’re interested in backtraces coming from Guile
processes that build derivations.  For that, we need to set COLUMNS in
the #:env-vars argument of ‘gexp->derivation’ or similar.

HTH!

Ludo’.
