emacs.scm: Suggest add emacs-next or emacs-snapshot

Suggest add emacs-next or emacs-snapshot and let guile-emacs inherit it, The reason is that
user can use it build emacs from emacs.git conveniently， for example:

    guix build emacs-snapshot --with-source=./emacs-snapshot-20151111.tar.gz

To use --with-source, all you need to do is to rename the tarball to
‘emacs-20151111.tar.gz’; after that, you can run:

  guix build emacs --with-source=emacs-20151111.tar.gz

That’s because --with-source expects the tarball name to match the
package name (info "(guix) Invoking guix build").

Now, it might make sense to also provide an ‘emacs-snapshot’ package,
built from a Git checkout and regularly updated.  Would you like to try
that?

I think the package would simply inherit from ‘guile-emacs’ and provide
a different ‘name’, ‘version’, and ‘source’.

Thanks,
Ludo’.

1. emacs can't build emacs.git's snapshot for some reason
2. I think let guile-emacs inherit emacs-snapshot or emacs-next is more reasonable, for  guile-emacs is a kind of emacs-next.

By the way, when I use the below command:
 
   guix build emacs-snapshot --with-source=./emacs-snapshot-20151111.tar.gz

to build a new emacs-snapshot, How can i install it?  I can't find any help on manual....

At the momenti, i only use guix as a tool to build emacs-snapshot. but I find it is not easy use as evm, i have to switch back evm.

“guix build” will print a store item path at the very end.  You can ask
Guix to install that path directly:

    guix package -i /gnu/store/....

(I’m not sure about this but I remember doing something like this in the
recent past.)

Currently you have to do:

  guix package -i $(guix build emacs --with-source=…/emacs-20151111.tar.gz)

Not as convenient as one would like.  I guess we could add --with-source
directly in ‘guix package’.

I don't think it is a flexible way, i like the below:

    guix build emacs --with-source=~/my-own-emacs-dir --override-name=emacs --override-version=20151111

I agree and suggest add a way which can override name and verison, for
example:

  guix package -i emacs-snapshot --with-source=/path/to/emacs.git --override-name=emacs-snapshot --override-version=20151111

I don’t like to add override-name and override-version flags.  They
don’t seem very useful.  After all, every different build gets its own
directory in the store, so “override-version” seems to be useless.

“override-name” just duplicates the package name, so I fail to see how
it would be an improvement.

I do agree that it would be a little nicer if we could build and install
a package from a directory, rather than just from a tarball.

Currently the name and version are inferred from the file/directory name
passed to --with-source.  That seemed like a simple UI, at the expense
of less flexibility compared to what Feng Shu proposes.

It’s always possible to do something arbitrarily complex and then use
‘guix package --install-from-file’.

What’s missing though is the ability to pass --with-source to ‘guix
package’.

It’s already possible, but its name must match the package name.

Thanks,

I agree that’s more flexible but that’s also less nice as a UI.

And it’s not as simple as this.  Currently one can do:

  guix build emacs guile \
    --with-source=emacs-2123123.tar.gz --with-source=guile-12321.tar.gz

and it does the right thing.

Here we wouldn’t know what package --override-name and
--override-version apply to.

For non-trivial use cases, I would suggest writing a file like this:

  (use-modules (guix) (gnu packages emacs))

  (package
    (inherit emacs)
    (name "emacs-snapshot")
    (source "/path/to/some-file-or-directory.tar.gz"))

and then run:

  guix package --install-from-file=that-file.scm

WDYT?

It is a good tip, thanks!
