Hi guix! I want to output the deps of a package to
a writable file. Like say the "hello" world
package, I'd like to insert a file after, say the
install phase, so that later I could parse it and
serve it from a website. Here's a snip of what I
have:
#+begin_src scheme
(add-after 'install 'create-dependency-file
(lambda* (#:key inputs outputs #:allow-other-keys)
(call-with-output-file
(string-append
(assoc-ref outputs "out")
"/lib/python3.8/site-packages"
"/wqflask/DEPENDENCIES.txt")
(lambda (port)
(format
port "
#### System Inputs (generated from Guix)
|Name | Version | Home Page | Description |
|-----|---------|-----------|-------------|
|~a|
"
(apply
string-append
(map (lambda (input)
(let ((name (car input)))
(string-append
"| **" name "** | "
,(package-version
(specification->package name)) " | "
,(package-home-page
(specification->package name))
" |"
,(package-description
(specification->package name))
" |\n")))
inputs)))
))
))
#+end_src
That ^^ doesn't seem to work as I'd like it to. The output(truncated)
looks something like:
#+begin_src markdown

Notice that the version, home page and description
are repeated across rows. Herein lies my question:
How would you fetch the details of the inputs(like
version, home-page, description) etc etc from a
modifed phase. Do I need to create a closure from
which I can import the modules like say _(use (gnu
packages))_. How do I do that if that's the case?
Is it also possible to get the same information in
a fine grained manner, like say get the
propagated-inputs instead of getting /all/ inputs?

The reason you always get the same data is because you're assigning "name" inside the sexp (build-side), but you're using it inside tge unquote (host-side), so it refers to the name of the package you're building.
I think you're doing it wrong, because some input names have no corresponding package (see source for instance). Why not use the package data directly, like guix graph does for instance?

It is expected, as Julien explained.
Well, I have tried to uses modules in the builder in order to import
’specification->package’ but I failed. There is still something a bit
unclear for me: the arguments #:modules vs ’use-modules’. And for
example, I miss why
--8<---------------cut here---------------start------------->8---
(arguments
`(#:modules ((gnu packages))
…
--8<---------------cut here---------------end--------------->8---
fails. Moreover…
>>Notice that the version, home page and description
>>are repeated across rows. Herein lies my question:
>>How would you fetch the details of the inputs(like

…I am not convinced it is the right level to extract the
information you need since ’input’ is, e.g.,
;;; (("source" . "/gnu/store/hbdalsf5lpf01x4dcknwx6xbn6n5km6k-hello-2.10.tar.gz"))
;;; (("grep" . "/gnu/store/yhqc5imq7sn2sf9f48dj4gk12y4kw4s4-grep-3.4"))
;;; (("libc:static" . "/gnu/store/s3dcqzwqaakv1yx37by9chksdbkgih17-glibc-2.31-static"))
therefore you need ’specification->package’ to find back the package
mapping to the string in order to access the metadata (version,
home-page, etc.). Aside the issue that some do not have corresponding
packages (source, libc:static for instance). Aside the issue of
multiple versions, for instance compare the version of the ’gcc’ input
of ’hello’ returning the string “gcc” with:
--8<---------------cut here---------------start------------->8---
scheme@(guix-user)> (specification->package "gcc")
guix repl: package 'gcc' has been superseded by 'gcc-toolchain'
$1 = #<package gcc-toolchain@10.2.0 gnu/packages/commencement.scm:3836 7f3b72596640>
--8<---------------cut here---------------end--------------->8---
What do you want? Get the list of inputs and their metadata when typing
“guix install foo”? And this list becoming part of the outputs? Or
simply get somehow the list of inputs and their metadata? Which is
straightforward.
Well, I am interested by the answer of: is it possible to get the
metadata of the inputs in phases?
All the best,
simon

I think it would be easiest to compute this outside the package
definition and then add it as an input and just plop the precomputed
file into place in a custom phase.

I don't know how to do this. I've had a look at
guix/graph.scm and scripts/graph.scm... And I got
lost--- I'm not /yet/ a scheme guru... I reckon
I'll go with Efraim's suggestion which seems
easier to do :)
Thanks for the pointers!

Yes! Ideally I want to get details of the package
inputs, so that I could use that info to write to
a file somewhere in the outputs dir. The end goal
is to use that file to display (on some website)
the dependencies the project has. So when you do,
say, `guix install <my-awesome-package>`, as part
of your outputs, you also generate a file that
explicitly list the deps as part of your output ;)

Yes! I think this will do it for this case. Would
never have thought of that! Thanks!

The Efraim’s suggestion–also the Julien’s suggestion about use the
package data directly– is not what you are describing above. It is
“simply get somehow the list of inputs and their metadata, which is
straightforward.” :-)
Basically, first step you run “./pre-inst-env guix repl -- script.scm”
which contains ’package-inputs’ (or any other ’package-direct-inputs’,
’package-propagated-inputs’, etc.) with formatting and second step you
manually add to the package this generated file in one phase to get it
in the output.
The file ’script.scm’ is more or less one illustration in this blog
post:
<https://guix.gnu.org/en/blog/2020/reproducible-computations-with-guix/>
Now, is it possible to embed this first step in the package definition
as an extra phase and run it via ’invoke’ or similar?
(And I am still interested by the answer of «is it possible to get the
metadata of the inputs in phases?» :-))
All the best,
simon

Hi all!
Was finally able to hack something that
works! See below:

Yes it's possible. The trick is to use
"this-package" which can *only* be used inside a
package definition and no where else. Stumbled
across that when poring through some guix package
definitions, moreso skriblio.
Here's my working phase:
--8<---------------cut here---------------start------------->8---
(add-after 'install 'generate-dependency-file
(lambda* (#:key inputs outputs #:allow-other-keys)
(call-with-output-file
(string-append
(assoc-ref outputs "out")
"/lib/python3.8/site-packages"
"/wqflask/DEPENDENCIES.md")
(lambda (port)
(format
port "
#### System Inputs (generated from Guix)
|Name | Version | Home Page | Description |
|-----|---------|-----------|-------------|
|~a|
"
,(apply
string-append
(map
(lambda (input)
(let* ((pkg (cadr input))
(name (package-name pkg))
(version (package-version pkg))
(home-page (package-home-page pkg))
(description (package-description pkg)))
(string-append
"| **" name "** | "
version " | "
home-page " | "
description " | "
" |\n")))
(package-propagated-inputs this-package)))))
)))
--8<---------------cut here---------------end--------------->8---
