Default aggregation is 1 month (1M).

For example:

cpanapi --activity --author oalders

which will show the releases issued by author OALDERS

cpanapi --activity --author oalders --new

Same as the previous one, but will only show the new distribution release

cpanapi --activity --distribution HTTP-Message

which will show the releases for the distribution specified.

cpanapi --activity --module HTTP::Message

which will show the releases that depend on the module specified.

cpanapi --activity --module HTTP::Message --new

Same as the previous one, but only show new module release.

cpanapi --activity --new --interval 1M

which will show the new distribution releases across all authors.

autocomplete

This will trigger an API query to the endpoint /search/autocomplete and will return a list of files.

For example:

Possible operators are ==, !=, <=, >=, >, <, !

versions

Array. This specifies one or more versions for a distribution for which all its releases will be retrieved. This is used in conjonction with --show-release.

For example:

cpanapi --show-release --distribution HTTP-Message --versions 6.35 --versions 6.34

If you prefer, you can provide multiple version as a comma separated value, such as:

cpanapi --show-release --distribution HTTP-Message --versions 6.35,6.34

or, even:

cpanapi --show-release --distribution HTTP-Message --versions "6.35,6.34"

Note that the order of the versions specified is unimportant, because the MetaCPAN API will return the release in their version descending order.
