Hello Guix!
This patch series is to make ‘options->transformation’ public,
mostly so that users can directly translate package transformation
options to code they can use in manifests.
The second goal of the patch is to have a new “Defining Package
Variants” section that gives an introduction to this topic with
all the relevant pointers.
That’s it! Thoughts?
Ludo’.
PS: I swear this is the last non-trivial change I’d submit for 1.2.
:-)
Ludovic Courtès (6):
guix build: 'package-with-source' no longer takes a 'store' parameter.
guix build: Remove unnecessary (replacement #f).
guix build: 'options->transformation' no longer takes a 'store'
parameter.
guix build: Move transformation options to (guix transformations).
transformations: Raise '&formatted-message' exceptions instead of
'leave'.
doc: Add "Defining Package Variants" section.

+@section Defining Package Variants
+
+@cindex customizing packages
+@cindex variants, of packages
+One of the nice things with Guix is that, given a package definition,
+you can easily @emph{derive} variants of that package---for a different
+upstream version, with different dependencies, different compilation
+options, and so on. Some of these custom packages can be defined
+straight from the command line (@pxref{Package Transformation Options}).
+This section describes how to define package variants in code. This can
+be useful in ``manifests'' (@pxref{profile-manifest,
+@option{--manifest}}) and in your own package collection
+(@pxref{Creating a Channel}), among others!
+
+@cindex inherit, for package definitions
+As discussed earlier, packages are first-class objects in the Scheme
+language. The @code{(guix packages)} module provides the @code{package}
+construct to define new package objects (@pxref{package Reference}).
+The easiest way to define a package variant is using the @code{inherit}
+keyword together with @code{package}. This allows you to inherit from a
+package definition while overriding the fields you want.
+
+For example, given the @code{hello} variable, which contains a
+definition for the current version of GNU@tie{}Hello, here's how you
+would define a variant for version 2.2 (released in 2006, it's
+vintage!):
+
+@lisp
+(use-modules (gnu packages base)) ;for 'hello'
+
+(define hello-2.2
+ (package
+ (inherit hello)
+ (version "2.2")
+ (source (origin
+ (method url-fetch)
+ (uri (string-append "mirror://gnu/hello/hello-" version
+ ".tar.gz"))
+ (sha256
+ (base32
+ "0lappv4slgb5spyqbh6yl5r013zv72yqg2pcl30mginf3wdqd8k9"))))))
+@end lisp
+
+The example above corresponds to what the @option{--with-source} package
+transformation option does. Essentially @code{hello-2.2} preserves all
+the fields of @code{hello}, except @code{version} and @code{source},
+which it overrides. Note that the original @code{hello} variable is
+still there, in the @code{(gnu packages base)} module, unchanged. When
+you define a custom package like this, you are really @emph{adding} a
+new package definition; the original one remains available.
+
+You can just as well define variants with a different set of
+dependencies than the original package. For example, the default
+@code{gdb} package depends on @code{guile}, but since that is an
+optional dependency, you can define a variant that removes that
+dependency like so:
+
+@lisp
+(use-modules (gnu packages gdb) ;for 'gdb'
+ (srfi srfi-1)) ;for 'alist-delete'
+
+(define gdb-sans-guile
+ (package
+ (inherit gdb)
+ (inputs (alist-delete "guile"
+ (package-inputs gdb)))))
+@end lisp
+
+@cindex package transformations
+These are pretty simple package variants. As a convenience, the
+@code{(guix transformations)} module provides a high-level interface
+that directly maps to package transformation options (@pxref{Package
+Transformation Options}):
+
+@deffn {Scheme Procedure} options->transformation @var{opts}
+Return a procedure that, when passed an object to build (package,
+derivation, etc.), applies the transformations specified by @var{opts} and returns
+the resulting objects. @var{opts} must be a list of symbol/string pairs such as:
+
+@example
+((with-branch . "guile-gcrypt=master")
+ (without-tests . "libgcrypt"))
+@end example
+
+Each symbol names a transformation and the corresponding string is an argument
+to that transformation.
+@end deffn
+
+For instance, a manifest equivalent to this command:
+
+@example
+guix build guix \
+ --with-branch=guile-gcrypt=master \
+ --with-debug-info=zlib
+@end example
+
+@noindent
+... would look like this:
+
+@lisp
+(use-modules (guix transformations))
+
+(define transform
+ ;; The package transformation procedure.
+ (options->transformation
+ '((with-branch . "guile-gcrypt=master")
+ (with-debug-info . "zlib"))))
+
+(packages->manifest
+ (list (transform (specification->package "guix"))))
+@end lisp
+
+@cindex input rewriting
+@cindex dependency graph rewriting
+The @code{options->transformation} procedure is convenient, but it's
+perhaps also not as flexible as you may like. How is it implemented?
+The astute reader probably noticed that most package transformation
+options go beyond the superficial changes shown in the first examples of
+this section: they involve @dfn{input rewriting}, whereby the dependency
+graph of a package is rewritten by replacing specific inputs by others.
+
+Dependency graph rewriting, for the purposes of swapping packages in the
+graph, is what the @code{package-input-rewriting} procedure in
+@code{(guix packages)} implements.
+
+@deffn {Scheme Procedure} package-input-rewriting @var{replacements} @
+ [@var{rewrite-name}] [#:deep? #t]
+Return a procedure that, when passed a package, replaces its direct and
+indirect dependencies, including implicit inputs when @var{deep?} is
+true, according to @var{replacements}. @var{replacements} is a list of
+package pairs; the first element of each pair is the package to replace,
+and the second one is the replacement.
+
+Optionally, @var{rewrite-name} is a one-argument procedure that takes
+the name of a package and returns its new name after rewrite.
+@end deffn
+
+@noindent
+Consider this example:
+
+@lisp
+(define libressl-instead-of-openssl
+ ;; This is a procedure to replace OPENSSL by LIBRESSL,
+ ;; recursively.
+ (package-input-rewriting `((,openssl . ,libressl))))
+
+(define git-with-libressl
+ (libressl-instead-of-openssl git))
+@end lisp
+
+@noindent
+Here we first define a rewriting procedure that replaces @var{openssl}
+with @var{libressl}. Then we use it to define a @dfn{variant} of the
+@var{git} package that uses @var{libressl} instead of @var{openssl}.
+This is exactly what the @option{--with-input} command-line option does
+(@pxref{Package Transformation Options, @option{--with-input}}).
+
+The following variant of @code{package-input-rewriting} can match packages to
+be replaced by name rather than by identity.
+
+@deffn {Scheme Procedure} package-input-rewriting/spec @var{replacements} [#:deep? #t]
+Return a procedure that, given a package, applies the given
+@var{replacements} to all the package graph, including implicit inputs
+unless @var{deep?} is false. @var{replacements} is a list of
+spec/procedures pair; each spec is a package specification such as
+@code{"gcc"} or @code{"guile@@2"}, and each procedure takes a matching
+package and returns a replacement for that package.
+@end deffn
+
+The example above could be rewritten this way:
+
+@lisp
+(define libressl-instead-of-openssl
+ ;; Replace all the packages called "openssl" with LibreSSL.
+ (package-input-rewriting/spec `(("openssl" . ,(const libressl)))))
+@end lisp
+
+The key difference here is that, this time, packages are matched by spec and
+not by identity. In other words, any package in the graph that is called
+@code{openssl} will be replaced.
+
+A more generic procedure to rewrite a package dependency graph is
+@code{package-mapping}: it supports arbitrary changes to nodes in the
+graph.
+
+@deffn {Scheme Procedure} package-mapping @var{proc} [@var{cut?}] [#:deep? #f]
+Return a procedure that, given a package, applies @var{proc} to all the packages
+depended on and returns the resulting package. The procedure stops recursion
+when @var{cut?} returns true for a given package. When @var{deep?} is true, @var{proc} is
+applied to implicit inputs as well.

Naive question: what is the difference? Other said why? And so why not
replaces ’leave’ here and there by ’raise’+’formatted-message’?

Does it make sense to add a sentence explaining that the “guile” is the
name provided by the string in the ’inputs’ list of the package ’gdb’,
namely:
--8<---------------cut here---------------start------------->8---
(inputs
`(("expat" ,expat)
("mpfr" ,mpfr)
("gmp" ,gmp)
("readline" ,readline)
("ncurses" ,ncurses)
("guile" ,guile-2.0)
("python-wrapper" ,python-wrapper)
("source-highlight" ,source-highlight)
;; Allow use of XML-formatted syscall information. This enables 'catch
;; syscall' and similar commands.
("libxml2" ,libxml2)
;; The Hurd needs -lshouldbeinlibc.
,@(if (hurd-target?) `(("hurd" ,hurd)) '())))
--8<---------------cut here---------------end--------------->8---
? Because it can be confusing. Especially when the ’rewriting’ works
on symbols instead.

It's the only one that doesn't follow the same pattern as others, where
the change look quite similar: instead of (t store p) -> (t p) (source
(run-...)), also specified in the message.
If removing that comparison is intended, I think the commit message
should be changed. Otherwise it LGTM.
Happy hacking!

Probably Ludo can explain better, but the main difference I see is that
leave (guix diagnostics) calls exit, so the client code now can handle
these errors and it isn't forced to exit.
The patch LGTM. Just one extra comment, this changes some format
strings, so we shouldn't forget to send the latest pot files to TP as
soon as we generate the branch for the release.
Happy hacking!
Miguel

The main comment regarding this patch is that file has to be added to
po/guix/POTFILES.in, or the translations will be lost.
I've seen that you've changed some code identifiers, here:
> - (else (tarball-base-name (file-sans-extension file-name)))))

And there:

And these changes seem sensible as the match parameter is unused.
Other than the first comment, the patch LGTM.

Hi Ludo,
I've had to re-read some parts of the manual and the code of (guix
store) a bit to completely understand this one, so thank you for the
practical lesson too. :-)
To be sure that I understood it: the main difference is that now
package-with-source _stages_ (wink) the source download up to the gexp
compilation, isn't it? If that's the case, this LGTM and my quick
tests.
Happy hacking,
Miguel

Good catch! I guess I was hesitant here. I’ll re-introduce the test
using ‘run-with-store’ and all.

Exactly. In fact, ‘exit’ throws the 'quit exception, which one could
also catch, but it’s still nicer to throw &message or &formatted-message
within a module meant to be used as a library.

Yes, exactly. Now ‘package-with-source’ inserts an “inert”
<downloaded-file> record as the source of the package. The file is
actually downloaded when that <downloaded-file> object is “lowered”,
which happens when the package itself is lowered to a derivation.
Thanks for the review!
