bug#16187: Tabbed output of "guix package -l"

[Roel Janssen]

Hi,

Thanks for the report.

Roel Janssen <r...@moefel.org> skribis:

I'd like the output of a command like "guix package -l" to be tabbed
preserving all columns.

An example output of the current version:
Generation 68   dec 18 2013 12:46:45    (current)
  make  4.0     out     /nix/store/...
  automake      1.14    out     /nix/store/...
  ...

What I would like to see:
  make          4.0     out     /nix/store/...
  automake      1.14    out     /nix/store/...
  ...

The same applies for the output of "guix package -I" and "guix package

-A"

As discussed on IRC, the rationale (for -I and -A) was to have something

both human-readable and processable–that is, one can pipe it through

‘cut’ and extract the data. I think that’s an important property, for a

Unix command-line tool.

Now, ideally, ‘guix package’ would be just one of the user interfaces, with others being more user-oriented than command-oriented (see TODO)...

What do you think?

Ludo’.

Hello,

I think a separation between command-oriented and user-oriented
output is a good solution.

Kind regards,
Roel.
