guix environment ad-hoc manifests

[Reza Alizadeh Majd]

Hi Guix, 

working with guix environments, we can pass list of packages, using a
manifest file. we also can use --ad-hoc switch for additional packages
we need to add to the prepared environment.

it would also be great to be able to pass list of ad-hoc packages,
using a manifest file, something like --ad-hoc-manifest switch. or
maybe there is such option already available that I missed. 

Regards, 
Reza

What would that look like?  Just a file containing package names?

yes, a possible use-case would be to provide a development
environment for a software which is not packaged yet. during
development phase, we could easily update this manifest file and
include third-parties we need to use.

But isn’t this exactly what you can use a manifest file for already?
“guix environment” not only accepts a file that describes a package, but
also a manifest.

Thank you for your response, there is just a point that I don't
understand.

- when we add a package to environment, all of package inputs will be
added to the environment.
- using --ad-hoc switch, package itself will be present in environment.

now I want to know add a series of packages using --manifest, add them
directly to the environment (like --ad-hoc), or add inputs for each
package to environment?  


Thanks
Reza

From my understanding, as Ricardo said, the command:

   guix environment -m my-manifest.scm

is equivalent to:

  guix environment --ad-hoc pkg1 pkg2 pkg3

And moreover, you can also do:

  guix environment -m my-manifest.scm --ad-hoc my-package

What could be missing is to pass a manifest file and provide all the
required packages used to build all the packages listed in the
manifest.  Other said, there is no equivalent at the manifest level
of:

  guix environment pkg1 pkg2 pkg3

or even this:

   guix environment pkg1 pkg2 pkg3 --ad-hoc pkg4 pkg5 pkg6

To be clear, it is possible but the API is not straightforward.


Is it what you mean?

Hope that helps,
simon

Thanks for your response. yes this is exactly what I was looking for.

just from the "Guix Environment" document:

> Create an environment for the packages contained in the manifest

I assumed that manifest packages, would be acted like:

  guix environment pkg1 pkg2

which it seems that I was wrong.


Thanks

Or perhaps a solution could be to simply allow multiple --manifest
files, so that one could oneself distinguish between them via file name,
but Guix uses them as if their content was merged in one file instead?

It is already the case.  Try:

   guix environment -C -m manifest-1.scm -m manifest-2.scm

and the packages listed in both files manifest-1.scm and
manifest-2.scm are present in the environment profiles.


All the best,
