NAME ^

App::Pinto::Command::roots - show the roots of a stack

VERSION ^

version 0.09992

SYNOPSIS ^

  pinto --root=REPOSITORY_ROOT roots [OPTIONS]

DESCRIPTION ^

!! THIS COMMAND IS EXPERIMENTAL !!

This command lists the distributions that are the roots of the dependency tree that includes all the distributions in the stack. In other words, it tells you which distributions or packages you would need to install from this stack to get all the other distribution in the stack.

COMMAND ARGUMENTS ^

As an alternative to the --stack option, you can also specify the stack as an argument. So the following examples are equivalent:

  pinto --root REPOSITORY_ROOT list --stack dev
  pinto --root REPOSITORY_ROOT list dev

A stack specified as an argument in this fashion will override any stack specified with the --stack option. If a stack is not specified by neither argument nor option, then it defaults to the stack that is currently marked as the default stack.

COMMAND OPTIONS ^

--format FORMAT_SPECIFICATION

Format of the output of each record using printf-style placeholders. Valid placeholders are:

  Placeholder    Meaning
  -----------------------------------------------------------------------------
  %p             Package name
  %P             Package name-version
  %v             Package version
  %y             Pin status:                     (!) = is pinned
  %a             Distribution author
  %f             Distribution archive filename
  %m             Distribution maturity:          (d) = developer, (r) = release
  %M             Distribution main module
  %h             Distribution index path [1]
  %H             Distribution physical path [2]
  %s             Distribution origin:            (l) = local,     (f) = foreign
  %S             Distribution source
  %d             Distribution name
  %D             Distribution name-version
  %V             Distribution version
  %u             Distribution URI
  %%             A literal '%'


  [1]: The index path is always a Unix-style path fragment, as it
       appears in the 02packages.details.txt index file.

  [2]: The physical path is always in the native style for this OS,
       and is relative to the root directory of the repository.

You can also specify the minimum field widths and left or right justification, using the usual notation. The default format is %a/%f.

--stack NAME
-s NAME

List the roots of the stack with the given NAME. Defaults to the name of whichever stack is currently marked as the default stack. Use the stacks command to see the stacks in the repository.

EXAMPLES ^

Install all modules in the stack in one shot:

  pinto -r /myrepo roots | cpanm --mirror-only --mirror file:///myrepo

Generate a basic cpanfile that would install all modules in the stack:

  pinto -r /myrepo roots --format 'requires q{%M};' > cpanfile

CAVEATS ^

This list of roots produced by this command is not always correct. Many Perl distributions use dynamic configuration so you can't truly know what distributions need to be installed until you actually try and install them. Pinto relies entirely on the static META files to determine prerequisites.

But in most cases, this list is pretty accurate. When it is wrong, it typically includes too many distributions rather than too few. At best, this will have no impact because your installer will have already installed them as prerequisites. At worst, you may be installing a distribution that you don't really need.
