From: guix-commits
Subject: 61/63: gnu: commencement: Simplify Gash and Gash-Utils.
Date: Mon, 17 Feb 2020 16:01:08 -0500 (EST)

janneke pushed a commit to branch wip-bootstrap
in repository guix.

commit 11c6562bd5c2b969f6a61bee355c6ef3e461a757
Author: Timothy Sample <address@hidden>
AuthorDate: Mon Feb 3 10:51:07 2020 -0500

    gnu: commencement: Simplify Gash and Gash-Utils.
    
    This change does three things.  First Gash-Utils is updated to
    0.1.0.  Then, the bootstrap Gash and Gash-Utils packages are
    arranged to be built without using 'guild'.  Finally, instead of
    using a binary 'tar' via 'bootstrap-executable' to extract Gash and
    Gash-Utils, a self-extracting Scheme implementation of 'tar' and
    'gzip' is used instead.
    
    These three changes need to happen in concert to avoid breaking the
    bootstrap process.
    
    * gnu/packages/shells.scm (gash-utils): Update to 0.1.0; remove
    'autoconf' and 'automake' from 'native-inputs'; delete 'arguments';
    update the home-page, synopsis, and description.
    * gnu/packages/commencement.scm (bootar): New variable.
    (gash-boot): Replace 'tar', and 'xz' with 'bootar'; remove 'bash'
    and 'guile-source'; do not use 'guile-build-system' but rather
    'gnu-build-system' with some modified phases; disable tests.
    (gash-utils-boot): Likewise.
    (%boot-gash-inputs): Add 'bootar'; replace '%bootstrap-guile+guild' with
    '%bootstrap-guile'.
    (mes-boot): In the configure phase, do not reference 'GUILE_LOAD_PATH'
    as it is no longer set.

+standalone scripts for 'bzip2', 'gzip', and 'xz' that each support
+decompression to standard output.
+
+What makes this special is that Bootar is distributed as a
+self-extracting Scheme (SES) program.  That is, a little script that
+outputs the source code of Bootar.  This makes it possible to go from
+pure Scheme to Tar and decompression in one easy step.")
