Hi,

the author of paps (printing package for emacs) updated his package.

How can I download this new version in Guix?


I downloaded his new version through git clone ....
but I couldn't install it.

I used

guix package --install=/home/.../.../.../.../paps
but it said

not known package.

Kind regards

Try this:

  guix install paps --with-source=paps=file:///home/user/.../paps

No guarantee it'll work, though.  If it doesn't, you'll have to look into updating
it yourself.

Hi,

thanks

It started to bootstrap the file but failed.

phase `unpack' succeeded after 0.0 seconds
starting phase `bootstrap'
running './autogen.sh'
patch-shebang: ./autogen.sh: changing `/bin/sh' to 
`/gnu/store/4y5m9lb8k3qkb1y9m02sw9w9a6hacd16-bash-minimal-5.1.8/bin/sh'
./autogen.sh: line 4: glib-gettextize: command not found
./autogen.sh: line 7: autoreconf: command not found
./autogen.sh: line 8: ./configure: No such file or directory
error: in phase 'bootstrap': uncaught exception:

exit-status: 127 term-signal: #f stop-signal: #f>
phase `bootstrap' failed after 0.4 seconds
command "./autogen.sh" failed with status 127

Does that mean there is a bug in the file? and I have to wait until Guix 
updates the package : paps?

Kind regards

This is fairly easy to fix, and isn't exactly a bug; it's just the package is written
for the old source.  We just need to add the various autotools (autoconf, libtool, m4,
automake, etc) to the package's NATIVE-INPUTS until it works.  Why don't you have a go? :)

Hi,

paps 0.7.1   I have got already installed in my system.
this means that your proposed command tried to install the same version 
of this program.
Is it like this?


How can I update it myself?

Hi,

Then I would first need some hours of lessons from somebody who explains 
me everything!

Kind regards

Clone the source code:

  git clone https://git.sv.gnu.org/git/guix.git
  cd guix

Create a new branch to make your changes in:

  git branch wip-update-paps

Now you can either use a git "worktree" (a new directory for your branch) or the current
directory to edit the branch:

  git checkout wip-update-paps # to use the current directory
  git worktree add wip-update-paps # i prefer to use a new directory

If you choose to use a worktree, make sure to cd there:

  cd wip-update-paps

Build the source code, to make sure everything's working alright:

  ./bootstrap
  ./configure --localstatedir=/var
  make -j$(nproc) # using multiple jobs makes the build process *much* faster

Now figure out where the package is:

  guix show paps
  # ---8<---
  # location: gnu/packages/pdf.scm:1459:2
  # ---8<---

Open up that file:

  (define-public paps
    (package
      (name "paps")
      (version "0.7.1")
      (source
       (origin
         (method url-fetch)
         (uri (string-append "https://github.com/dov/paps/releases/download/v"
                             version "/paps-" version ".tar.gz"))
         (sha256
          (base32 "1z1w1fg2bvb8p92n1jlpqp3n9mq42szb2mqhh4xqmmnmfcdkpi9s"))))
      (build-system gnu-build-system)
      (inputs
       (list pango))
      (native-inputs
       (list intltool pkg-config))
      (home-page "https://github.com/dov/paps")
      (synopsis "Pango to PostScript converter")
      (description
       "Paps reads a UTF-8 encoded file and generates a PostScript language
rendering of the file through the Pango Cairo back end.")
      (license license:lgpl2.0+)))

Change the ``version'' number to the latest version:

      (version "(***VERSION***)")

Now, Guix verifies downloaded code using a hash to check whether it's been
corrupted or tampered with, so we need to change that too.  To get the new
hash, use ``guix download'':

  guix download https://github.com/dov/paps/releases/download/v(***VERSION***)/paps-(***VERSION***).tar.gz

This will print out a string that looks a bit like what's currently in the
(sha256 (base32 "...")).  Replace that string with the one from ``guix download''
to update the hash.

Now, rebuild:

  make -j$(nproc)

We can use ``./pre-inst-env'' to test out our changes:

  ./pre-inst-env guix build paps

It'll probably fail with the error you got before, so try adding the needed
autotools dependencies to native-inputs:

  (native-inputs
   (list autoconf automake intltool libtool m4 pkg-config))

If that doesn't work, try adding gnu-gettext, too:

  (native-inputs
   (list autoconf automake gnu-gettext intltool libtool m4 pkg-config))

Now build and test again:

  make -j$(nproc)
  ./pre-inst-env guix build paps

If it works, you can send it as a patch to the Guix mailing list.  Follow the
instructions on <https://git-send-email.io>'s first two pages to set up Git's
email features, but *don't do anything else from there*.

Now you need to commit your change:

  git commit

Your commit message should look something like this:

  gnu: paps: Update to (***VERSION***).

  * gnu/packages/pdf.scm (paps): Update to (***VERSION***).

This is the typical GNU commit message format, called ChangeLog.

Now use ``git send-email'' to send the patch to guix-patches (see
<https://guix.gnu.org/manual/devel/en/html_node/Sending-a-Patch-Series.html>
for more information):

  git send-email -1 --base=master --to=guix-patches@gnu.org

A patch email should appear on the Guix mailing list, ready to be applied
by the maintainers :)
