Hi!

The other day on IRC zimoun noted that ‘guix pull -l’ doesn’t work for
them because it prints those long package lists, which incidentally
makes it slower.

This series changes ‘guix pull -l’ so that by default it only prints
channel info and news:

  New `guix shell' command supersedes `guix environment'
    commit 746584e0ca200e7bf51b139ceb36c19ea81d6ef1

    A new `guix shell' command is now available.  It is similar to `guix environment', but with a
    more convenient interface (`guix environment' is deprecated but will remain available until
    May, 1st 2023).  The main difference compared to `guix environment' is that the "ad hoc" mode
    is the default.  Thus, to create an interactive environment containing Python, NumPy, and
    SciPy, you would run:
    
         guix shell python python-numpy python-scipy
    
    To get a development environment for, say, Inkscape, pass the `-D' flag:
    
         guix shell -D inkscape
    
    Another difference is that running `guix shell' without arguments loads `manifest.scm' or
    `guix.scm' for the current directory or an ancestor, provided you allowed it.  The command
    maintains a cache to speed up access to such environments.
    
    Run `info "(guix) Invoking guix shell"' for more information.

One can pass ‘--details’ to get view new/upgraded packages:

Last, ‘guix pull -l’ pipes its output to $PAGER by default.

Thoughts?

Ludo’.

Ludovic Courtès (4):
  pull: '--list-generations' doesn't list package changes by default.
  ui: 'with-paginated-output-port' gives access to the wrapped port.
  ui: 'display-generation' uses color when talking to a pager.
  pull: '--list-generations' pipes its output to the pager.
