-module(format_lib_supp).
%%%---------------------------------------------------------------------
%%% Description:
%%% This module contains generic formatting functions for the SUPPort
%%% tools.
%%% The main parts are:
%%% 1) print_info. Prints information tagged by 'header', 'data',
%%% 'items' and 'newline'.
%%%---------------------------------------------------------------------
%% intermodule exports
-export([print_info/2, print_info/3]).
%%---------------------------------------------------------------------
%% Format is an ordered list of:
%% {header, HeaderString}
%% {data, List_Of_KeyValue_tuples}
%% The KeyValues_tuples will be printed on one line
%% (if possible); 'Key: Value'.
%% Elements in the list may also be single terms, which are
%% printed as they are.
%% {items, {Name, Items}}
%% Items is a list of KeyValue_tuples. Will be printed as:
%% 'Name:
%% Key1: Value1
%% KeyN: ValueN'
%% {newline, N}
%% Any other format will be ignored.
%% This list is printed in order. If the header clause is present,
%% it must be the first element in the format list.
