Bio::Phylo::Unparsers::Newick - Serializer used by Bio::Phylo::IO, no serviceable parts inside

This module turns a tree object into a newick formatted (parenthetical) tree description. It is called by the Bio::Phylo::IO facade, don't call it directly. You can pass the following additional arguments to the unparse call:

	# by default, names for tips are derived from $node->get_name, if 
	# 'internal' is specified, uses $node->get_internal_name, if 'taxon'
	# uses $node->get_taxon->get_name, if 'taxon_internal' uses 
	# $node->get_taxon->get_internal_name, if $key, uses $node->get_generic($key)
	-tipnames => one of (internal|taxon|taxon_internal|$key)

	# for things like a translate table in nexus, or to specify truncated
	# 10-character names, you can pass a translate mapping as a hashref.
	# to generate the translated names, the strings obtained following the
	# -tipnames rules are used.
	-translate => { Homo_sapiens => 1, Pan_paniscus => 2 }	

	# array ref used to specify keys, which are embedded as key/value pairs (where
	# the value is obtained from $node->get_generic($key)) in comments, 
	# formatted depending on '-nhxstyle', which could be 'nhx' (default), i.e.
	# [&&NHX:$key1=$value1:$key2=$value2] or 'mesquite', i.e. 
	# [% $key1 = $value1, $key2 = $value2 ]
	-nhxkeys => [ $key1, $key2 ]	

	# if set, appends labels to internal nodes (names obtained from the same
	# source as specified by '-tipnames')
	-nodelabels => 1

	# specifies a formatting style / dialect
	-nhxstyle => one of (mesquite|nhx)

	# specifies a branch length sprintf number formatting template, default is %f
	-blformat => '%e'
