Re: Video Documentation for GNU GUIX (an Outreachy project)

[Lakshmi Prasannakumar]

Hi Gábor and Björn,

I was trying to install the new packages with the documentation mentioned in the Outreachy site as below

https://www.gnu.org/software/guix/manual/en/html_node/Defining-Packages.html

Here I see a code to define a package for 'Hello' and I assume in order to define a package for Anaconda I just need to change this code with source, url details of Anaconda something like this as mentioned in the bold.

(define-module (gnu packages Anaconda)

  #:use-module (guix packages)

  #:use-module (guix download)

  #:use-module (guix build-system Anaconda)

  #:use-module (guix licenses)

  #:use-module (gnu packages gawk))

(define-public Anaconda

  (package

    (name "Anaconda")

    (version "3.10")

    (source (origin

              (method url-fetch)

              (uri (string-append "Anaconda's Website URL" version

                                  ".tar.gz"))

              (sha256

               (base32

                "0ssi1wpaf7plaswqqjwigppsg5fyh99vdlb9kzl7c9lng89ndq1i"))))

    (build-system gnu-build-system)

    (arguments '(#:configure-flags '("--enable-silent-rules")))

    (inputs `(("gawk" ,gawk)))

    (synopsis "Hello, GNU world: An example GNU package")

    (description "Guess what GNU Hello prints!")

    (home-page "http://www.gnu.org/software/hello/")

    (license gpl3+)))

Request you to guide me to get a better understanding here as I saw one more page in this url, that uses some pull commands to run some build etc.

Yes, that is correct.

Yes, that is correct. We usually recommend to add a package we have an
importer for. Anaconda could be a good candidate, if you wish to
package it, and I guess we have a lot of unpackaged dependencies of
anaconda.
Note that you have to package all the dependencies to package
something for guix. Packaging a single dependency would do for now.
Please see https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-import.html
for
more information about importers. (For example R packages from CRAN or
bioconductor have a good quality importer)

Not yet, we should leave that for later, if it is possible.
