# Lintian::Group(3)

## NAME

Lintian::Group -- A group of objects that Lintian can process

## SYNOPSIS

```
 use Lintian::Group;
 my $group = Lintian::Group->new('lintian_2.5.0_i386.changes');
```

## DESCRIPTION

Instances of this perl class are sets of processables.  It allows at most one source and one changes or buildinfo package per set, but multiple binary packages (provided that the binary is not already in the set).

## METHODS

- $group-\>pooldir

  Returns or sets the pool directory used by this group.

- $group-\>source\_name

  - $group-\>source\_version

  - $group-\>binary

  Returns a hash reference to the binary processables in this group.

- $group-\>buildinfo

  Returns the buildinfo processable in this group.

- $group-\>changes

  Returns the changes processable in this group.

- $group-\>source

  Returns the source processable in this group.

- $group-\>udeb

  Returns a hash reference to the udeb processables in this group.

- jobs

  Returns or sets the max number of jobs to be processed in parallel.

  If the limit is 0, then there is no limit for the number of parallel jobs.

- processing\_start

  - processing\_end

  - cache

  Cache for some items.

- profile

  Hash with active jobs.

- "saved\_direct\_dependencies"

  - "saved\_direct\_reliants"

  - $group-\>name

  Returns a unique identifier for the group based on source and version.

- process

  Process group.

- $group-\>add\_processable($proc)

  Adds `$proc` to `$group`.  At most one source and one changes `$proc` can be in a `$group`.  There can be multiple binary `$proc`'s, as long as they are all unique.  Successive buildinfo `$proc`'s are silently ignored.

  This will error out if an additional source or changes `$proc` is added to the group. Otherwise it will return a truth value if `$proc` was added.

- get\_processables

  Returns an array of all processables in `$group`.

- get\_installables

  Returns all binary (and udeb) processables in `$group`.

  If `$group` does not have any binary processables then an empty list is returned.

- direct\_dependencies (PROC)

  If PROC is a part of the underlying processable group, this method returns a listref containing all the direct dependencies of PROC.  If PROC is not a part of the group, this returns undef.

  Note: Only strong dependencies (Pre-Depends and Depends) are considered.

  Note: Self-dependencies (if any) are *not* included in the result.

- direct\_reliants (PROC)

  If PROC is a part of the underlying processable group, this method returns a listref containing all the packages in the group that rely on PROC.  If PROC is not a part of the group, this returns undef.

  Note: Only strong dependencies (Pre-Depends and Depends) are considered.

  Note: Self-dependencies (if any) are *not* included in the result.

- spelling\_exceptions

  Returns a hashref of words, which the spell checker should ignore. These words are generally based on the package names in the group to avoid false-positive "spelling error" when packages have "fun" names.

  Example: Package alot-doc (#687464)
