Ruby install

[Pjotr Prins]

Hi,

I have a working Ruby installation at

  https://gitorious.org/guix/pjotrps-guix/source/61d21fad72d49cbbf0135b5ac7362bb0f64167fa:gnu/packages/ruby.scm

This is my first GUIX package (I have written Nix packages before), so
please have a look.

I intend to patch rubygems so gems get installed in a $HOME dir
specifically named after the SHA. This will accomodate people who just
want to use rubygems.

I am also going to add particalur gems to GUIX, each going into its
own expression. That will be a bit tricky because I don't want
Rubygems to install dependencies. Not sure how the Nix guys did it, so
I will study that.

Do we have a HOWTO on how to run expressions in the Guile debugger?
Never used that and would like to see how individual statements
evaluate in LISP.

I am really impressed with GUIX, and I think it is a no-brainer to use
a real functional programming language for this. Thanks Ludo and
others!  I just wish I could use GUIX on servers where I don't have (and
won't get) root access. Or is there a way? With Nix I could run as a
normal user.

Pj.

Overall looks good to me!  A couple of comments:

59.            (substitute* (filter file-exists?
60.                             '( 
61.                               "ext/readline/readline.c"
62.                             ))

Here we can assume that the file exists I believe, so the ‘filter’ call
can be removed.

67.            (substitute* (filter file-exists?
68.                             '(
69.                               "configure"
70.                               "configure.in"
71.                               "Makefile.in"
72.                               "ext/pty/pty.c"
73.                               "io.c"
74.                               "lib/mkmf.rb"
75.                               "process.c"
76.                               "test/rubygems/test_gem_ext_configure_builder.rb"
77.                               "test/rdoc/test_rdoc_parser.rb"
78.                               "test/ruby/test_rubyoptions.rb"
79.                               "test/ruby/test_process.rb"
80.                               "test/ruby/test_system.rb"
81.                               "tool/rbinstall.rb"
82.                               "tool/config.guess"
83.                              ))
84.              (("/bin/sh") (which "sh"))))

Likewise.  In addition, I think only the .rb and .c files need to be
patched, since the others are already handled automatically, normally.

(In the future please send it as an in-line patch.)

It may be helpful to have a ‘ruby-build-system’, akin to
‘python-build-system’ but with the right incantations (info "(guix)
Build Systems").

Basically there are two approaches.  From the command line, like this:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guile
GNU Guile 2.0.11.20-4338f
Copyright (C) 1995-2014 Free Software Foundation, Inc.

Enter `,help' for help.
scheme@(guile-user)> ,use (gnu packages python)
scheme@(guile-user)> ,use (guix)
scheme@(guile-user)> (define s (open-connection))
scheme@(guile-user)> python
$1 = #<package python-3.3.5 gnu/packages/python.scm:46 2946840>
scheme@(guile-user)> (package-derivation s python)
$2 = #<derivation /gnu/store/k0lvsy8jwcw0amv1rsmii2cvwfnmn2gz-python-3.3.5.drv => /gnu/store/ij8xgynicdmnzb7pzmyb6bqi17s0ll3y-python-3.3.5 3f4fdc0>
scheme@(guile-user)> (build-derivations s (list $2))
$3 = #t
--8<---------------cut here---------------end--------------->8---

But the best thing, if you use Emacs, is to use Geiser, as noted in
‘HACKING’.  In addition to a REPL, it brings stuff like autodoc,
jump-to-definition, expression evaluation from the buffer, etc.

It’s the same as Nix, which means that if the daemon cannot run as root,
then it’s usable in a “degraded” mode (info "(guix) Build Environment
Setup").

I was imprecise here. It is my first real foray into LISP. What I
meant is that it is great to use a real programming language with the
most important functional characteristics of recursion and anonymous
functions :)

I believe much of Nix could be greatly simplified if they had opted
for this route. Did you see NixOS is speeding up the ranks in
distrowatch? I bet that is partly due to GUIX.

That is good news. Anyone here using it as such?

The key benefit with using a general-purpose programming language is
that you get all the tools (REPL, IDE, debugger, compiler, i18n, etc.),
and it makes the whole thing composable.

Composability means that it’s trivial to implement things like ‘guix
build --with-source’, or Nikita’s ‘guix prefetch’ command, or the
program that builds <http://www.gnu.org/software/guix/package-list.html>,
for example.

I am still in bootstrap mode on an aging CenOS6 compute cluster, so I
am not in package writing mode. I need to be able to install Nix/Guix
without root. I work in short stretches on the problem (I wish it
was easier! I tried bootstrapping Guix, but failed).

At this point I got Nix 1.6.1 working with this script
https://github.com/pjotrp/nix-no-root/blob/master/scripts/nix-bootstrap-home.sh,
which is derived from the Nix wiki.

Now, I need to patch Nix to work with PAM/LDAP (that fix is in 1.7,
but that does source tree does not compile with my script, I tried
that yesterday), next I need to upgrade the Guix package in Nix (it is
at 0.3) and then I can continue playing with packages.

The Ruby package needs work too because we need a sane way to handle
gems. I need to understand the way Nix does it and what Guix does with
Python. The way it is done now in Nix looks fairly complex. I don't
think we want automated gem processing.

I can confirm that the package builds and runs. :)

How about naming this 'ruby' instead?  Then, in the ruby package module,
you can add a prefix to the imported symbols to avoid a name clash.

    #:use-module ((guix licenses) #:prefix license:)

You would then refer to the license variable as 'license:ruby'.

Thanks for this!  I was struggling with my own Ruby package.  Now I
don't have to waste anymore time on it.  :)

Now, we need to get gems working and write a gem->guix import script!

I don't have the patches quite ready yet, but I wrote a working Ruby
build system for building gems locally.  I'll share the patches when I
wake up.

guile ERROR: Unbound variable: sha256

I can’t reproduce it.  Could it be that guix/derivations.scm was
modified in your local tree, such that it misses the
#:use-module (guix hash) line?  Is there a warning when compiling
guix/derivations.go?

Thanks,
Ludo’.
