Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
* guile-readline/ice-9/readline.scm (history-file): When the HOME
environment variable is unset, use the empty string in its place.
---
Hi,
If a Guile program uses the readline module without setting HOME, it
will fail due to string-append getting a #f argument. In particular,
this necessitates workarounds when starting GNU dmd early in the boot
process. To illustrate this, try:
guile -c '(use-modules (ice-9 readline))(display "working\n")'
And then:
env -u HOME \
guile -c '(use-modules (ice-9 readline))(display "working\n")'
Let me know if there is a better alternative for handling this case, and
I can send another patch.
Thanks.
David

I would prefer to use "." in its place, instead of the empty string.
Otherwise, the patch looks good to me.
Can you send an updated patch?
Thanks!
Mark
