Re: [Nix-dev] Google Summer of Code 2017

[Anderson Torres]

No problems, guys! Just keep calm and carry on! We gained another year
to rally efforts on a GSOC 2018!

Thomas, can I add my ideas to your Github repo?

I would suggest three big fat proposals:

1 - The most flamewar-igniting one: getting rid of systemd dependency!
It would be very nice if the init system was selectable, with a sane
default (as openrc).
It would be hard as hell to port certain software as Gnome stack, but
I think it can be solved.

2 - Another for the even more courageous would be run a Nixos+kNetBSD
(or kFreeBSD), as in Debian. It would be the definitive test for
portability and independence of Nix model.

3 - Another set of defaults for the stdenv, as musl+clang.

[Nix-dev] A suggestion of Nixpkgs contributing workflow - help and opinions needed

[Anderson Torres]

Hello, Nixers!

I am developing a very particular style of workflow for Nixpkgs. I
will describe it here:

0 - Choose a package to port for Nixpkgs - say, higan.

1 - Find the current release of your locally installed NixOS:

$ nixos-version

16.09pre79453.32b7b00 (Flounder)

2 - Checkout to the corresponding ID on your nixpkgs clone tree (in
the case, 32b7b00), and give to it a name - here, Current:

$ git checkout 32b7b00
[... omitted messages...]
$ git checkout -b Current

3 - Branch again:

$ git checkout -b higan-test

4 - Hack it and commit:

$ nano pkgs/top-level/all-packages.nix
$ testThePackage
$ git add pkgs/top-level/all-packages.nix
$ git commit

5 - Another branch! Now, for pull-request

$ git checkout -b higan-rebase
$ git rebase upstream/master
$ git push -fvu origin higan-rebase

And, after it, just fill a pull-request for upstream Nixpkgs!

The idea of pass 2 above is to use "Current" as a base for more
branches and packages - so I can just checkout to Current and branch
it to, say, mgba.

---

My question is: how can I "update" Current if I update Nixos locally,
AND propagate the update to the derived branches?

Re: [Nix-dev] User-oriented nixpkgs documentation (was: ioquake3 on nixos)

I prefer to start a documentation project, like the FreeBSD

I think we can just use a type of 'sed' in the text - it would be very
powerful! But I don't know if it is viable. Also, because
"substituteInPlace" is just a function script,

I think the same. Docbook is extremely verbose and full of ugly XML
tagging, I don't like it.
Also, it is easier to use a lightweight markup as pandoc or Asciidoc.
The learning curve is smoother than XML, and it can be easily
converted to Docbook or anything we like.

But, about documentation: what do you think on a "NixOS Handbook",
like the FreeBSD Handbook? We can reach a wider audience if we use
such a style of handbook.

Re: [Nix-dev] Regarding the Wiki

[Anderson Torres]

Why not to unofficialize wiki? It can be hosted in a site like wikia,
with no official interference or support of NixOS staff.
It would free some resources on official site and be better maintained.
Also, we can use Stack Exchange to answer questions, and the
configurations files could be hosted on Github or Bitbucket.

Re: [Nix-dev] Perl -> C++

[Anderson Torres]

The main motivation is to get rid of dependencies. It would greatly
help in porting Nix to other architectures and systems.

bind and complete are Bash builtins as far as I can remember. They are

[Nix-dev] Out-of-tree building for autotools packages in a Nix expression

[Anderson Torres]

Hello, Nixers!

How can I instruct Nix to use an out-of-tree building in a GNU
Autotools-based package? There are some packages I want to build, and
generally the upstream developers recommend the building directory
being out of the unpacked source tree.

An example is INTERCAL, an esoteric language I am playing around.

Thanks in advance!

[Nix-dev] How to build a download list for "sneaknet"?

[Anderson Torres]

Hello, Nixers!

I want to know if there is a way to build a download list for a
package and its dependencies.

There is a similar command on NetBSD's pkgsrc.
It builds a shell script, and that script, when executed in any
machine with Internet connection, downloads the sources and its
dependencies for a package. The script is just a list of command like
"wget -c url1 url2 url3".

There is a way to build the URL list, using Nix commands or some script?

Re: [Nix-dev] What is the end game?

[Anderson Torres]

My two satoshis on it.

Looking at our famous brothers as Slackware, Gentoo, Debian, Arch
etc., we can trace and forecast a situation:
* Small projects can be handled by single developers, with high
independence from upstream maintainers (as myself taking care of mpv
and xiphos);
* Medium and huge projects can be handled by sub-teams, such as GCC
NixOS team, or Haskell NixOS Team; these huge teams will be more
tightly connected to upstream, with developers in common.

In practical terms, I prefer the expressions centralized on our Nixpkgs release.

2015-08-30 13:12 GMT-03:00 Nicolas Pierron nicolas.b.pier...@gmail.com:
 I don't think the #1 is unpractical, if you consider that these
 fetches are properly mirrored, which we currently do with channels.

 To try to steer the discussion in the direction I'm most interested in, what
 if binutils had a release.nix in its repo? How about gcc or clang? What
 would the expressions look like in nixpkgs? The options I can see:

 1) nixpkgs is full of e.g., binutils = (import ${fetch* { url =
 url/to/binutils; sha256 = abc; }}/release.nix).build
 2) Duplicate the release.nix of binutils in nixpkgs
 3) Some combination of 1 and 2, where metadata, name, dependencies are
 expressed in nixpkgs, but build instructions are in the repo's release.nix
 4) ???
 5) profit

 Actually, I'm not sure #4 and #5 are relevant, but I couldn't think of other
 options.

 #1 seems impractical because a single nix-env would result in thousands of
 fetchurls
 #2 seems undesirable due to duplicated information
 #3 seems like our best bet, but I don't know what that would look like

  Let's say for a moment that Nix has taken over the world, and every

  What does nixpkgs look like in this world? Does it duplicate the
  individual
  package .nix files in their respective repositories? Does it only
  duplicate
  minimal information (dependencies and meta) from the remote
  repositories?

 If we were in such world, then the module would probably be best
 handled by upstream maintainers.

 The way NixOS modules are working, we need all of them before
 evaluating any configuration, thus we would need to have a copy of the
 configuration file, even if we have to download it.  In such case, it
 makes sense that NixOS list of modules would be built out-of an
 aggregate of fetched resources.

 Thus, if we ever do a copy, we should do it with an url and a hash,
 and have one of the multiple output of packages be the NixOS module
 that we will aggregate, as-if it was a generic post-install script.

 Then, the problem with Hydra, is slightly different.  Currently hydra
 does not provide any stable (tagged) version.  I guess we could
 experiment the previous suggestion, but I would prefer to have
 multiple instances of this problem before attempting any generic
 solution as described above.  In the mean time, I think having your
 own copy of hydra, and using it to aggregate the module which is
 inside might be the best solution.

 I find no /boot/grub/grub.cfg on the NixOS partition, not even a 'grub'

Well, I think you just want:

1 - The Nix package manager language - it is easy;
2 - A local package expression respository with your own idiosyncrasy.

To 2, it is just to create a Git local branch with your preferred
versions of your favourite packages. To build them, maybe setting up
an Hydra server would be helpful, or even the nix-serve idea from
above messages.

 On reproducible deployments using git revisions - it solves the problem,

 You don't have to embed a git revision in your nix expressions; I don't
 like that solution much either. What we do at BetterCompany is always refer
 to nixpkgs by an expression like import nixpkgs {}.  Then we have
 $NIX_PATH include nixpkgs=~/.nix-defexpr/channels/nixpkgs. That means we can
 manage our version of nixpkgs using nix-channel.

 More generally, we include a default.nix and shell.nix in the root
 directory of all our repositories, and then have another repository similar
 to nixpkgs that bundles everything up, provides library functions etc.
 That's also in $NIX_PATH, so we can use import ourpkgs {} to get access to
 cross-repository dependencies, custom derivations functions etc.

 Finally, we tie it all together with Hydra, Nixops and a bit of custom
 code to help with deployments.

 Hope this helps, and I'm happy to go into more detail if you have specific
 questions.

 Colin

Re: [Nix-dev] release-15.07

[Anderson Torres]

BUT, are the bugs considered 'blockers', too? Maybe an 'intermediary
release' should be used.

Also, there is some progress about documentation in general?

 No, there are still a number of blockers:

 The only remaining blocker is now the closure size increase:

   https://github.com/NixOS/nixpkgs/issues/8990

 There are some pending fixes for this issue in the staging branch. So once 
 those
 are merged, we should be able to branch 15.07.

 I typed more, and got the following info:

 $ more
 The program ‘more’ is currently not installed. It is provided by
 several packages. You can install it by typing one of the following:
   nix-env -i busybox
   nix-env -i util-linux-curses

 So I think you just need to install one of those packages.

 No no, it's not about install.

 Add utillinuxCurses to the buildInputs list of gawk and check if that
 fixes the build.

But, why the normal install of NixOS channels just work, and gawk in a
local mirror is not?

 you could also write docbook syntax offline and then upload your stuff
 using a git-pull request. a good place would probably be the nixos
 documentation.

 There used to be a package for heroku in nixpkgs. I recently found need of
 it and it seems to be gone. What happened to it? How can it be installed on
 NixOS these days? I tried downloading and installing, but it fails to find
 ruby.

Normally, you declare ruby in tha buildInputs array. Or try to pass
Ruby installed dirs as parameters for configure script.

 How can I download it?

 Use the following code:

   src = fetchgit {
  url = git://repo.or.cz/dockapps.git;
  rev = 38c74350b02f35824554ce0c4f0f251d71762040;
  sha256 = 0g9cwhlqg065fbhav4g4n16a4cqkk9jykl3y0zwbn5whhacfqyhl;
   };

 Explanation:

 When you download a dockapp from Windowmaker site you are redirected to
 a git repo site where you get a snapshot out of it. The id of the
 snapshot is the long hexadecimal string you are getting.
 The above code does a checkout of the whole dockapp-git directory.
 The only thing you have left to do is point to the directory where your
 actual dockapp is:

 postUnpack = sourceRoot=\${sourceRoot}/dockapp-dir;


So you are just saying we need to download all dockapps and build one by one?

It appears to be better handled with a multiple-output derivation! I
will do some research on Nix docs about it.

Re: [Nix-dev] Fetching variable and unpredictable URL download link

2015-03-01 15:21 GMT-03:00 Harald van Dijk har...@gigawatt.nl:
 Hi,

 The problem here is not with the file names, but that you don't actually get
 the same file every time. The file is generated by the server on-the-fly,
 and the mtimes of the files in the download you get depend on the precise
 moment you download it, as you can tell by inspecting the output of

   tar tvf $download

 This is fundamentally incompatible with any package manager that checks that
 source archives are downloaded correctly.

 The original website


 http://lancre.ribbrock.org/en/binabit_en/wmsmpmon_en/wmsmpmon-changelog_en.html

 appears to link to a stable archive that you should be able to use instead.

The problem here is: some dockapps have no official site anymore. In
fact, there are some with links to Web Archive!

But the idea of Breno is cool! I will try it.


 Cheers,
 Harald van Dijk

Re: [Nix-dev] Make Firefox/Chrome use OpenJDK instead of Oracle JDK?

[Anderson Torres]

2015-02-14 21:06 GMT-02:00 Chad Joan chadj...@gmail.com:
 Hello!

 Is it possible to make Firefox/Chrome use OpenJDK instead of Oracle JDK?
 If so, how?

 I have read this article: https://nixos.org/wiki/Enable_Browser_Plugins

 Here is my configuration.nix: http://pastebin.com/hA2eV7TM

 In my first attempt, I tried to follow the wiki advice, including the jre =
 true suggestion, but with ignoring the suggestion to download Oracle JDK in
 advance.  Predictably, when I ran nixos-rebuild switch, it failed and
 complained about needing Oracle JDK to be manually downloaded.

 Next, used the same configuration, but with one exception: I tried adding
 pkgs.jdk to my environment.systemPackages list.  This is the attribute name
 I get when I run 'nix-env -qaP --description .*jdk.*' (I still wonder why
 that query doesn't bring up the Oracle JDK as well...).  This failed the
 same way as the first attempt.

 I am suspecting that pkgs.jdk doesn't fulfill the JDK/JRE dependency given
 by firefoxWrapper.  This would be unintuitive to me, because any JDK should
 be able to satisfy a JDK/JRE dependency.  Hopefully I just misunderstand how
 NixOS is resolving dependencies :)

 I am trying to avoid the Oracle JRE because I don't want it to bug me with a
 fetch restriction every time a system update bumps my Java version.  I've
 been through this with Gentoo, and it has made me put extra effort into
 avoiding things with licenses that require manual downloading.

 At some level, I am hoping to find something analogous to (or capable of
 replacing) Gentoo's virtual packages.  virtual packages in Gentoo would be
 used for things like Java, where there are multiple implementations for a
 piece of software.  A package (ex: firefox) can depend on a virtual package
 (ex: jre) to avoid locking the admin into a specific implementation, and a
 virtual package can be installed by installing any one of its
 implementations.:

Maybe it could help:

 Thanks in advance!

 I get the following error:

 error: The option 'services.xserver.windowManager.windowmaker' defined

 I've tried to do some research and I think this is because in the
 following file:
 nixpkgs/nixos/modules/services/x11/window-managers/default.nix

 windowmaker is not defined in the imports.
 Can someone please look into this problem or help me find a solution.

 Second:

 Is it also possible to add libpng and libjpeg to the build inputs.
 This is in file
 nixpkgs/pkgs/applications/window-managers/windowmaker/default.nix.
 This allows windowmaker to also use png and jpeg icons. In the current
 build it only supports xpm icons and bitmaps.

 What about other languages as Python, Perl etc.? I know it is against

 Well, that's the current state of the art.  They are both used in
 Nixpkgs and some Nix-related tools.  They are an improvement over Bash
 scripting, but I believe we might as well go all the way and use a
 functional language.

 Also the Nix model allows us to compile all our scripts easily (just
 apply a function), which might hold some benefit in terms of startup and
 switch times.  There is little reason to use interpreted scripts when
 you have a fast compiler.

So, Chicken appears to be a good choice: it can be both interpreted
and compiled, very fast and with little overhead. And it can be easily
debugged - it's functional, after all!
I think Haskell is as much as overkiller - there is even a project
about it: Nix Evaluator in Haskell[1]. It is easier to use a less
ambitious and more funny language (in the Python sense of funny
programming).

What about to start a project to implement Chicken as script
supporting language for Nix? I would like to help!

Re: [Nix-dev] Use Haskell for Shell Scripting

[Anderson Torres]

2015-01-31 10:22 GMT-02:00 Ertugrul Söylemez ert...@gmx.de:
 At this current point in time, GHC is packaged in a poor manner, with
 GHC being unbelievably huge. Dynamic linking is the answer, which
 isn't done by default.

 I have actually experimented with using Haskell (and a few other FP
 languages) as a substitute for shells.  It is feasible if you disable
 dynamic linking.  The non-Haskell libraries are still linked
 dynamically, but the reference to the GHC derivation is then gone.  This
 brings the closure of a Haskell hello-world script from a huge 1.1 GiB
 down to a mere 131 MiB (on my x86_64 system), which makes it on par with
 shell scripts.

 However, static linking is probably not a good idea.  The resulting
 scripts are on the order of megabytes and can quickly approach a few
 tens of them.  To really fix this and make Haskell viable as a shell
 substitute we need to split the GHC derivation.  There should be a pure
 library derivation and a separate compiler derivation.  The former
 should be as small as possible.  Ideally there would be one derivation
 per library.

 The other languages I have tried are Scheme (via Chicken), Curry (via
 PAKCS), SML (via mlton) and Idris.

 Before I present my results, let me clarify what I think a script is:
 It is a string that I can run through a simple Nix function, which gives
 me a derivation that contains a runnable version of that string, either
 binary or shebanged.  This derivation pulls a reasonably sized closure
 along with it.  I can choose to combine many such runnable scripts to a
 single derivation using buildEnv, which is often very useful.  In other
 words:  For the language blah there is a simple, deterministic,
 unconfigurable function that would have the following signature in a
 hypothetical typed Nix:

 blahScript : String - Derivation

 This function can be a special case of a slightly more powerful function
 that takes a directory and a main entry point, because if we choose to
 use a better language, we might as well choose to utilise its module
 system, if it has one, for some of our larger scripts.

 Now to my results:  All of the above languages, except Curry, work more
 or less, if all you need to do is to start programs or move files
 around.  As soon as you need to do operating-system-specific stuff
 (e.g. `unshare` on Linux) it gets less juicy, because unless someone has
 written a nice high-level library you need to touch the FFI.

 Chicken Scheme worked best for that, because rather than trying to model
 the syscall in the language, you can just dump C code into it.  Not a
 nice and clean solution, but a working one for the many cases when you
 just need to -- you know -- get stuff done.

 Haskell works, because lots of the OS bindings can be found on Hackage,
 including Linux-specific libraries.  But it does require a slightly more
 expressive 'haskellScriptWith' function.  You need to be able to tell it
 what you depend on.

 SML works and produces surprisingly small executables.  It loses at the
 library end, because there aren't many OS-specific libraries around (or
 I couldn't find them).  Also some of the advanced FFI tooling that I'm
 used to from Haskell seems to be missing.  Finally I would say that the
 syntax is too verbose for quick scripting (but that's subjective -- I
 have seen people use VB.NET for scripting).

 You might be interested why Curry didn't work.  Simple: I couldn't
 figure out how to write a program.  Actually I went through the whole
 tutorial, did all the exercises (they aren't really difficult to a
 Haskell programmer) and then skimmed through the whole PAKCS manual.  I
 could write extremely elegant algorithmic code and was quite amazed at
 the beauty of this language, even compared to Haskell.  But in the end I
 still didn't know how to turn all this beautiful Curry code into an
 executable file that I can run without invoking PAKCS explicitly.
 Something with a shebang or ideally something binary.  It would probably
 be possible to write wrapper scripts, but let's just wait until one of
 the implementations becomes mature enough for systems programming.

 Finally there is Idris.  It is a beautiful language that comes with
 reasonable editor integration and a lightweight syntax.  It compiles to
 executable binary code and has a carefully designed yet useful FFI.
 Sounds good for scripting.  On the other hand it is very young and
 documentation is far from mature.  Not that I would mind its youth, but
 I do mind the barrier to entry at this point.  At the very least when
 other authors don't understand my code, it should be reasonably obvious
 where to look for answers.  Also the library landscape is very flat, so
 bootstrapping might use most of your time, if you choose to use Idris
 for systems-level scripting at this point.

 The most viable options seem to be Chicken Scheme and Haskell.  Both are
 well documented and have a usable FFI.  Chicken produces much smaller
 executables, 

Re: [Nix-dev] Windowmaker not properly defined.

[Anderson Torres]

I will verify it now.

2015-01-29 9:09 GMT-02:00 Berno Strik dutchma...@gmx.com:
 New user of NixOS so bare with me.
 I'm running NixOS 14.12.

 First:

 I've noticed that I can not use:
 services.xserver.windowManager.windowmaker.enable = true.
 I get the following error:

 error: The option 'services.xserver.windowManager.windowmaker' defined
 in '/etc/nixos/configuration.nix' does not exist.

 I've tried to do some research and I think this is because in the
 following file:
 nixpkgs/nixos/modules/services/x11/window-managers/default.nix

 windowmaker is not defined in the imports.
 Can someone please look into this problem or help me find a solution.

 Second:

 Is it also possible to add libpng and libjpeg to the build inputs.
 This is in file
 nixpkgs/pkgs/applications/window-managers/windowmaker/default.nix.
 This allows windowmaker to also use png and jpeg icons. In the current
 build it only supports xpm icons and bitmaps.

 Thanks in advance.

 Thanks Stewart. Do you happen to know if other nix commands (nix-shell,
 nix-build) use or ignore the extraCmds attribute? Or if any build phase uses
 it. I haven't found much documentation or code so far.

 I made some progress based on an earlier suggestion, by simply adding
 environment variables in the call to mkDerivation. The package is a library
 and want to propagate the variables to another library that depends on this
 one, and so on, downstream.


I think you can use setup hooks. Do a simple git grep setupHook on
nixpkgs tree, and you will find a lot of interesting setup scripts...

A good example is to set QTDIR on Qt4 scripts.

[Nix-dev] [Trinity-on-NixOS] Annoucing my project: packaging Trinity Desktop Environment to Nixpkgs

[Anderson Torres]

Hello, Nixers and Trinity users!

I am Anderson Torres, a wannabe Computer Scientist (I am studying to
admissional exams for a Brazilian CS undergrad course), and there is
about one year I am a NixOS user.

I want to port/package Trinity for NixOS, because I really liked the
old KDE3.x series! I used KDE 3.x when I started using Linux Slackware
and open source in 2004.

Well, I will use the tag [Trinity-on-NixOS] when I need to talk about
my project of porting an ask some questions.

Well, many thanks in advance!

[Nix-dev] Erlang Package Manager

[Anderson Torres]

Hello!
I am Anderson Torres. I'm a wannabe computer scientist, and a regular
NixOS user.

Recently at nix-dev mailing list [N1], Eric announced that the
developers of Erlang were discussing the need of a package manager. I
read the message of Joe Armstrong about using Nix.

I think using Nix is very attractive:
- we are a small team by now, and we need more programmers and
beta-testers (as almost any big project).
- also, we can serve as a platform for popularizing Erlang.

I am not an Erlang programmer, but as an active NixOS user, I
regularly maintain Nix expressions for some good softwares [N2]. So,
maybe I can help answering questions about Nix, and even programming
some small testing apps!

Many thanks in advance!
Waiting for input,
Anderson

This is my first problem - systemd is a bit bloated and mysterious.
I don't like the idea of big blobs doing everything on a system. It

But, modifyng the way we treat about services and modules is
revolutionary! It is just like Nix is for package management, applied
to system maintainance :)


 As a final bonus this is so difficult and ugly to solve with systemd
 that we would feel a much greater temptation to get rid of it. =)

 Let me know what you think.  If this idea finds acceptance, I'm happy to

[Nix-dev] How can I write a library inside Nixpkgs? (for Bitcoin and friends...)

Hello, Nixers!

I want to make a small library to help create CryptoCoins (or Altcoins).
Nowadays, there is a small bunch of altcoins in Nix. The most recent
is Darkcoin, by myself :)

I want to make something like #includealtcoins-templates.nix. In
fact, these altcoins are built almost the same way:

1 - Define one or two generic functions (like mkAutotoolsCoin,
mkGitCoin, mkTarballCoin etc.);
2 - Use the functions to write a builder for the coin.

My idea is to put the generic functions in a same file, and the
specific coins are described in separate files.

I think my question is a bit newbie, but can someone help me here?

Archlinux+AUR and start porting them!

 Also, I'd like to mention that I'm considering a rather serious long-term
 committment to NixOS if things work out, though I'm waiting for Gnome to
 become slightly more stable before transitioning full-time on my main
 computer. I am particularly interested in using/participating in the

 rather than as a core system plus packages, and from what I can tell NixOS
 seems to have great potential in this area.

1 - After some time, I have tried to update my system. But my Internet
connection is very poor, so I tried to download libreoffice using
wget:

$ wget -c 
http://cache.nixos.org/nar/1azl6p7a1ajqj1n62mj5bfwaajapljgqvw1xr7xhl6zzw74440x5.nar.xz


How can I use that file for now on?

2 - There is some way to set options on curl inside nix-env

Re: [Nix-dev] custom dwm/windowManager package on /run/current-system

[Anderson Torres]

As far as I know, dwm is configured by source-patching some files. It
doesn't use anything like '~/.dwmrc' files, it really modifies C
source code!

Well, we can use some derivation like patches = [ patch1 patch2 ];

 Good evening,

 I've been playing around with NixOS for a while, I have my own NIXPKGS repo
 with a custom version of dwm, the window manager.

 The problem is I can install my custom dwm build, but when I boot the old
 dwm remains(the one in the NixOS original channel) in
 /run/current-system/sw/bin/dwm.

 What ends up in /run/current-system/sw/bin/* is controlled by the
 environment.systemPackages option. (Installing with nix-env won't add
 anything to this directory.)

 I can install it for root(default profile) and my user because I can see a
 change I made to 'dwm -v', but I cannot change the version that boots. I
 located the hash and the current version working for boot, but I don't know
 If I have to install it for a different profile, make a derivation in my
 configuration.nix, etc.

 I don't use dwm, so I don't know if this applies to that specific
 case. Some NixOS modules have options to specify which derivation to
 use for the component it configures. For example, for the tomcat
 server, there is a services.tomcat.package option. It defaults to
 pkgs.tomcat7, but you can specify something else if you want.

 If there is no option you can try using

 nixpkgs.config = {
   packageOverrides = pkgs: {
 dwm = myCustomDwmDerivation;
   };
 };

 in configuration.nix to supply your own definition of 'dwm', used
 across the whole system.

[Nix-dev] Popularizing Nixpkgs/Nix/NixOS among FLOSS (Free/Libre and Open Source Software) developers

[Anderson Torres]

Hello, Nixers!

I was thinking on it some days ago. How about popularize NixOS among
FLOSS software developers?

It is very common among FLOSS developers to point out precompiled
packages or some similar facilities for the most famous operating
systems and distros, like Ubuntu/Debian/Fedora mirrors, Slackware
unofficial slackbuilds, AUR Archlinux, Gentoo overlays, the famous
*BSD freshports/pkgsrc...

Why not to contact some of them we are packaging and ask them to cite
us out? It would be a good idea in many sights:

- We would become more famous, which would attract more hackers to our projects;

- We would suggest bugfixes on various softwares, namely those full of
hackings on Nixpkgs. The Nixpkgs approach is a bit different from
those of other distros/OSes and it helps to find some obscure bugs,
mainly the lack of a serious dependency control and some tacit
assumptions (like ldconfig, absolute paths, undocumented features,
etc.);

- Our suggestions would be a valuable benefit from all other package
managers - after all, we are suggesting bugfixes on serious,
insidious, hard-to-find packaging bugs.

- We can serve as an indirect buildfarm for most of FLOSS world, with
our Hydra servers. Well, I don't know if our Hydra server is really
prepared for a so hard and huge task, but it would be even improved
by donations from great companies (we would be famous now, remember?
:D )


What about this, guys?

[Nix-dev] Ordering the downloads of nixos-rebuild

[Anderson Torres]

Hello, boys! I have a question...

My internet connection is not so good, and I want to know how can I
put some ordering on nixos-rebuild switch downloads. My idea is to
make it download the more heavier, disk/network-consuming packages
(texlive, kdelibs etc) first.

There is some way to do it?

Or even, to produce a simple machine-generated URL list, to use it
later in a command like wget -c -i package-list.txt, without even
modify nix-store?

My inspiration here is a pkgsrc command, I don't rememeber perfectly now...

Re: [Nix-dev] Package archeology in nixpkgs

[Anderson Torres]

Maybe a secondary git branch would be good to implement it.
Em 31/08/2014 00:32, Daniel Peebles pumpkin...@gmail.com escreveu:

 Hi all,

 I've had a sudden urge to do some Haskell archeology and that led me
 to a question about how we feel philosophically about keeping
 abandoned projects and old versions of live projects in nixpkgs. I
 think it could be valuable to preserve important pieces of Haskell
 history (and perhaps other projects) and it seems like nix is uniquely
 positioned to be able to do that well. I don't propose keeping all
 versions of all the compilers around, but I'd like to pick out key
 points in history and preserve them.

 In particular, I was thinking of attempting to get the following working:
 - HBC: perhaps the original Haskell compiler. I'd probably aim for a
 version that implements Haskell 1.4 and one before that standard was
 even proposed. Polymorphic map and (++) in Prelude!
 - NHC: can build it with HBC
 - GHC: the latest version that supports linear implicit parameters,
 because they're gone now and I think people should be able to tinker
 with them

 The nice thing about doing this sort of thing with compilers is that
 they tend to not have many dependencies, but I expect I might also
 need to package up an old version of yacc for HBC. If it starts
 getting too messy I might abandon the project, but I think it could
 work fairly nicely. This would also pave the way to exploring other
 interesting abandoned projects like fudgets and such.

 How do people feel about this? Is it something I should maintain
 independently of nixpkgs or does it belong in the main repo?

 Thanks,
 Dan

[Nix-dev] Error packaging tilda (about gettext, glade and expat)

[Anderson Torres]

Hello, Nixers! I need some help here.

I am trying to package Tilda[1], a quake-like terminal emulator. The
expressions are here on my private Nixpkgs branch [2].

But I found an error. Here is an eternal pastebin [3]. I used an
nix-shell, and after running 'sh autogen.sh', I ran a simple 'make'
command.

The relevant text for me is in the final lines:

 /nix/store/fsb...-gettext-0.18.2/bin/xgettext: Language glade is not 
 supported. xgettext relies on expat.

  This version was built without expat.

How can I solve this? Some patch, or a new version of gettext, or some
heinous trick (like the obscure ldcpp code, maybe)?

 Hi all,

 I've been messing around with the nixos 'graphite' service lately. I
 thought the module was a bit thin on the documentation side, so I
 started to search online. I came across this graphite puppet
 module[1], and what struck me is that there is no way that our current
 man configuration.nix can provide that kind of detail for each
 service, without being completely unreadable.

 So, how about we add a manpage for each service.name? I think it
 would be a good idea to still have everything in man
 configuration.nix, although man nixos-service-TAB-TAB would probably
 be just as easy to navigate.

 Does that sound like a good idea to you? Is it easy to do? I don't
 know where to begin :-)

[Nix-dev] [mate-on-nixos] All help needed (caja compiles but doesn't run)

[Anderson Torres]

Well, I am really stuck in my huge project, mate-on-nixos [1]...

I have a bunch of problems trying to compile caja. Some of them are
related on a not so old message[2].

I tried to use the wrapProgram trick. Now the message changes a bit:

(caja:14864): GLib-GIO-ERROR **: Settings schema 'org.mate.background'
is not installed

and trace-traps.

Unhappily, I don't know how to fix, or even investigate, that type of error.
And I think that type of error will be very frequent, after all it is
a huge desktop environment!

Can someone help me? :/

[Nix-dev] 32bit on 64bit Nix (chroot?)

[Anderson Torres]

About this, there is some way to make a 32-bit chroot on NixOS the s-me way
as the Archlinux tutorials (
https://wiki.archlinux.org/index.php/Install_bundled_32-bit_system_in_Arch64
)?

 Tim,

 I wish I had more information (I've only used NixOS in server
scenarios), but I would suggest first looking at pkgsi686Linux, which is
the entire nix packages with `system' overridden as i686-linux. There's
also callPackage_i686, incase you want to declare your own package that is
strictly 32bit. I'm always idling on #nixos, so feel free to ask some
questions there too, and I'll see if I can offer any advice.

 Greetings,

 I am new to NixOS, and finally tried it out, going through a bare-metal
 installation to a USB drive (I wanted to make sure I could get
 everything working on my laptop, for the possibility of switching out
 Ubuntu for NixOS). The documentation was clear and concise,
 however, it is not at all clear how to install support for running 32
 bit application on the 64bit OS. I did stumble on a logged conversation
 on the IRC channel, where installing stdenv_32bit was mentioned. But it
 was not entirely clear what that does.

 I am trying to run the dynamic binary for Skype. I will also be
 installing Wine, and a licensed copy of Codeweavers CrossOver Office. I
 know Skype depends on 32bit versions of Qt, and several other libraries,
 but right now, it would be progress to just get a 32bit version of libc
 installed.

 Any help in this regards will be greatly appreciated!

 Thanks!

boot.loader.grub.extraConfighttp://nixos.org/nixos/manual/#opt-boot.loader.grub.extraConfig

 You're missing braces, as callPackage takes two parameters, e.g.:

[Nix-dev] Mate Desktop on NixOS - some help needed

[Anderson Torres]

Hello, Nixers!

Well, since I use NixOS, I feel the desire and necessity to package Mate
Desktop (http://mate-desktop.org/). I am a bit lazy and not so
self-confident, however. Anyway, I need to do it - and started the task
today!

My idea was initially to use some of Gnome{2,3} or KDE 4.x constructions in
all-packages.nix. But they are very complicated to me, and I am not so
confident to use them. So I just 'hacked' the e17 expression, changing e17
to Mate:

[file=nixpkgs/top-level/all-packages.nix]
  mate = recurseIntoAttrs (
let callPackage = newScope pkgs.mate; in
import ../desktops/mate { inherit callPackage pkgs; }
  );
[/file]

I am starting small: first, compile mate-common, then add packages one at
time.

[file=nixpkgs/desktops/mate/default.nix]
{ callPackage, pkgs }:
rec {
  mate-common = callPackage ./core/mate-common.nix;
}
[/file]

[file=nixpkgs/desktops/mate/core/mate-common.nix]
{ stdenv, fetchurl, pkgconfig, gtk-doc }:

stdenv.mkDerivation rec {

  name = mate-common-${version};
  version = 1.9.0;

  src = fetchurl {
url = http://pub.mate-desktop.org/releases/1.9/${name}.tar.xz;;
sha256 = 0f2k9xv22amihdq3kdvzn2na7vcf36j5b7sg9hmpnx88jccn3z3m;
  };

  meta = {
description = MATE Core development macros;
homepage = http://mate-desktop.org/;
license = stdenv.lib.licenses.gpl21;
  };
}
[/file]

When I run a shell, it barfs:

$ nix-shell --dry-run --show-trace --max-jobs 1 nixpkgs/default.nix -A
mate.mate-common
error: expression does not evaluate to a derivation (or a set or list of
those)

I am a bit confused. What am I doing wrong?

[Nix-dev] Passing args to builder.sh

[Anderson Torres]

Hello, Nixers!

I want to know how can I pass some options to a builder.sh script.

I am maintaining a package for 8086tiny. It is not very
autoconf-style, in fact it is completely ad-hoc: a single Makefile
with a gcc file.c command. I am using an external builder.sh script
to install it.

But I want to pass a parameter, say localBios. If 0, builder.sh will
not install a locally assembled BIOS file; if 1, it will assemble and
install a BIOS.

How can I do it in Nix?

[Nix-dev] About using clang+llvm as default 'stdenv' compiler

[Anderson Torres]

Hello, Nixers!

I was thinking about a thing here.

1 - How can I set a new C compiler for stdenv? I want to use llvm+clang as
default compiler toolchain when running nix-build, etc. (Yes, I like some
masochistic testing...)

2 - Using a different compiler certainly affect the object code produced -
and in NIX it is propagated through the /nix/store tree as a different
hash. But, technically, both compilers would produce 'equivalent' object
codes.

The default toolchain is gcc, but my local chain is clang+llvm. So, can I
use at the same time a, say, Firefox compiled by Hydra and updated on the
unstable channels, and a local, 'clang7ed' version of Firefox?

 This is because banning firmware packages is really too masochistic at

 And it is not interestig for anyone. Firmwares generally are byte-copied
 to the device, and it doesn't affect the source at all. It is very

 It is not a so grave issue indeed. After all, even the interesting

Many thanks, boy! In fact, both tests, kernel and nixos-version, appointed

2014-03-18 0:51 GMT-03:00 James Cook james.c...@utoronto.ca:

 Hi Anderson (cc list for web-search-ability),

 I looked at /nix/store/g0hwyp1ip5q399hppgb8mzpxfy6fhq7f-install-grub.pl
 line 213 (the same file exists on my system).  It looks like that
 error would be caused if you have any profile
 (/nix/var/nix/profiles/system-###-link) which are abnormal.  So see if
 any of your profiles are missing the file nixos-version -- e.g. if
 the following command produces any output, then some of your profiles
 are missing it*.

   for i in $(echo /nix/var/nix/profiles/system-*-link); do test -f
 $i/nixos-version || echo missing in $i; done

 If some profiles are missing that file, and you don't need them,
 consider deleting those or just moving them somewhere else if you
 don't want to lose them (but then the next garbage collection will get
 them if you move them).

 James


 *Even if some are missing nixos-version, they ought to still work as
 long as another complicated test works (I'm continuing to read after
 line 213). The complicated test is: there should be a file called
 kernel, and if you ls -l that file to see which directory it really
 lies in, e.g:
 $ ls -l system-272-link/kernel
 lrwxrwxrwx 3 root nixbld 64 Dec 31  1969 system-272-link/kernel -
 /nix/store/0bp0h8m0zh2dnv9s8j9fdmagpjxwb9lw-linux-3.13.3/bzImage
 then you should see a directory under lib/modules there, e.g. in my case,
 $ ls
 /nix/store/0bp0h8m0zh2dnv9s8j9fdmagpjxwb9lw-linux-3.13.3/lib/modules
