pugilua

An almost one-to-one lua binding for pugixml.

Usage

Use the visual studio project to compile in Visual Studio. The release build will be copied into the Lua/lib folder, where you can start lua directly and use the library by calling require 'pugilua'. Follow the test and the binding definitions in contrib/pugilua/pugilua_lib.cpp for API differences from the original C++ API. Pugilua objects reside in the pugi 'namespace' in Lua.

Example of usage:

require 'pugilua'


---- reading ----
local doc=pugi.xml_document()
local res=doc:load_file [[..\..\scripts\pugilua\pugilua.vcxproj]]

print(res.description)

local node1=doc:root():child('Project')
local query1=doc:root():select_nodes('Project/PropertyGroup')

local n=query1.size
for i=0,n-1 do
  local node=query1:get(i):node()
	local attribute=query1:get(i):attribute()
	print(node.valid,node.path)
	local a=node:first_attribute()
	while a.valid do
		print(a.name)
		a=a:next_attribute()
	end
end

---- creating ----
doc:reset()
--- from the tutorial
-- add node with some name
local node = doc:root():append_child("node")

-- add description node with text child
local descr = node:append_child("description")
descr:append(pugi.node_pcdata):set_value("Simple node")

-- add param node before the description
local param = node:insert_child_before("param", descr)

-- add attributes to param node
param:append_attribute("name"):set_value("version")
param:append_attribute("value"):set_value(1.1)
param:insert_attribute_after("type", param:attribute("name")):set_value("float")

doc:save_file("tutorial.xml")

See an imperfect example of dumping an xml file in a less verbose format, or a filter of vcproj or vcxproj source files into lua tables

API differences

• There's no explicit cast to boolean of the pugilua objects, hence the classes xml_parse_result, xml_node and xml_document have a boolean property valid
• lua classes have no inheritance
• Getter methods are mapped to lua properties and not methods

Dependencies

• pugixml the original library
• lua the language, Lua 5.1.4 from luaforwindows, but it should work for every proper lua which is supported by LuaBridge
• LuaBridge for the declarative bindings to Lua
• premake4 for generating make files
