Sourcing a script in phases

Sourcing a script in phases

[phodina via]

Hi,

is there a way to source a script in the phases?
I tried to do:

(invoke "source" "env.sh")
or
(invoke "." "env.sh")

But it didn't work since they are builtin in the shell.

I had the same problem and ended up doing

(invoke "bash" "-c" "source env && ./command")

not the most elegant, but it did work.

Hi,

It's probably not the right answer, but for lack of time to find the
actual solution when I faced the same problem as you, here is what I
did:

https://gitlab.com/edouardklein/guix/-/blob/beaverlabs/beaver/packages/python-xyz.scm#L191

#+begin_src scheme
#:builder
      (begin
        (use-modules (guix build utils))
        (let* ((bash (assoc-ref %build-inputs "bash"))
               (requisomatic (assoc-ref %build-inputs "requisomatic"))
               (dir (string-append (assoc-ref %outputs "out") "/bin"))
               (fname (string-append dir "/requisomatic-server")))
          (mkdir-p  dir)
          (with-output-to-file fname
            (lambda _
              (display (string-append "#!" bash "/bin/bash\n"))
              (display "source /run/current-system/profile/etc/profile\n")
              (display "REQUISOMATIC_DB_FILE=$1 gunicorn --bind=$2 --pid=$3 requisomatic:app\n")))
          (chmod fname #o755)
          #t))))
#+end_src

Basically this creates a shell script that sources whatever you want to
source, and then call the executable you want to call.

This is not exactly what you want to do, but you can use this technique
to create a script that will run the build commands you want to run, and
then call it during the build phase.

Again, this is probably not the right answer.

Cheers,

Edouard.

Hi,

thanks for both ideas.

I went the easiest path and opted for:


(invoke "bash" "-c" "source env.sh && kmk")


Not the most polished line of code but it moves me a step ahead :-D

FIY: I'm attempting to build Virtualbox
