Dear Guix,
I'm stuck and could use some advice. I have R scripts which use the
httr2 R package (r-httr2) to make HTTP calls. These scripts do not run
out of the box inside a guix environment created by guix shell because R
makes the wrong assumption by default about where the web certificates
are. After reading the mailing list and the info manual, I found a
kludge workaround where I can define CURL_CA_BUNDLE environment variable
inside of R relying on GUIX_ENVIRONMENT. Now I'm looking for a less
tedious and more automated way of setting that environment variable. I
would prefer to have a single shell script which sets up my guix
environment setting that environment variable. Right now, I have a list
of commands which works.
$
CUSTOM_EMACS=$HOME/path/to/custom-configuration-with-necessary-R-packages
$ cd $CUSTOM_EMACS
$ guix shell -m manifest.scm # interactively the next two lines run
inside of this shell
$ export
CURL_CA_BUNDLE="$GUIX_ENVIRONMENT/etc/ssl/certs/ca-certificates.crt"
$ emacs --init-directory="$CUSTOM_EMACS"
Since the guix shell command takes control of the process, the last two
lines cannot be run in a script. What is an intuitive way to make the
shell do the same thing as I would do interactively? I'm guessing there
are some shell scripting concepts I am overlooking. However, I am hoping
this sort of issue is so common that there is a solution which is also
intuitive.
Thanks,
Kyle
