Re: using an SRFI that is not available in Guile

[Attila Lendvai]

thank you Maxime!

with your guidance, i have managed to add guile-srfi-189 next to the other 
guile-srfi-NNN packages in guile-xyz.scm (a slightly tested diff is attached).

but when i grep for how these guile-srfi-NNN packages are actually used within 
guix, then i don't see any hits unfortunately.

i tried the following to do a quick test of my new package:

$ ./pre-inst-env guix shell guile-srfi-189
$ ./pre-inst-env guix repl
scheme@(guix-user)> ,use (srfi srfi-189)
While executing meta-command:
no code for module (srfi srfi-189)

how do i introduce it into the guix codebase, without breaking e.g. 
bootstrappability?

i guess i need to add it as an input and a propagated-input to the guix package 
in package-management.scm? and then progress a kind of bootstrap stage/step, so 
that i can then `#:use-module (srfi srfi-189)` it in configuration.scm?

probably by recording the new input as a commit, and then guix pull'ing it into 
my user's profile? and only after that can i start using it within the guix 
codebase?

if that is the case, then is there a simpler/shorter way to test my new 
guile-srfi-189 package before i go through all this dance?

pointers to readings are also welcome.

or alternatively, if it's really this complicated, then i'd welcome if someone 
more experienced "documented" the process in the form of git commits... ;)

“Lenin was certainly right. There is no subtler, no surer means of overturning 
the existing basis of society than to debauch the currency. The process engages 
all the hidden forces of economic law on the side of destruction, and does it 
in a manner which not one man in a million is able to diagnose.”
