CRAN release 0.8.0

nanonext 0.8.0

New Features

• Implements stat(), an interface to the NNG statistics framework. Can be used to return the number of currently connected pipes for a socket, connection attempts for a listener/dialer etc.
• Implements parse_url(), which parses a URL as per NNG. Provides a fast and standardised method for obtaining parts of a URL string.

Updates

Please review the following potentially breaking changes, and only update when ready:

• Using socket() specifying either 'dial' or 'listen', a failure to either dial or listen (due to an invalid URL for example) will now error rather than return a socket with a warning. This is safer behaviour that should make it easier to detect bugs in user code.
• opt() and 'opt<-'() have been implemented as more ergonomic options getter and setter functions to replace getopt() and setopt(). These will error if the option does not exist / input value is invalid etc.
• subscribe(), unsubscribe() and survey_time() now return the Socket or Context invisibly rather than an exit code, and will error upon invalid input etc.
• survey_time() argument name is now 'value', with a default of 1000L.
• nano Object methods $opt, $listener_opt, and $dialer_opt re-implemented to either get or set values depending on whether the 'value' parameter has been supplied.

Other changes:

• Bundled 'libnng' source updated to v1.6.0 pre-release (8e1836f).
• Supported R version amended to >= 2.12, when person() adopted the current format used for package description.
• Internal performance enhancements.
