Linux 2.6 - man page for webtool (linux section 3erl)

webtool(3erl)			     Erlang Module Definition			    webtool(3erl)

       webtool	-  WebTool  is a tool used to simplify the implementation of web based tools with

       WebTool makes it easy to use web based  tools  with  Erlang/OTP.  WebTool  configures  and
       starts the webserver httpd.

       start()-> {ok,Pid}| {stop,Reason}

	      Start  WebTool  with default data, i.e. port 8888, ip-number, and server-
	      name localhost . If port 8888 is in use, port 8889 is tried  instead.  If  8889  is
	      also in use, 8890 is tried and so on. Max number of ports tried is 256.

	      The mime.types file and WebTool's own HTML files are assumed to be in the directory
	      webtool-<vsn>/priv/root/conf .


	      Types  Path = string() | standard_path
		     Data = [Port,Address,Name] | PortNumber | standard_data
		     Port = {port,PortNumber}
		     Address = {bind_address,IpNumber}
		     Name = {server_name,ServerName}
		     PortNumber = integer()
		     IpNumber = tuple(), e.g. {127,0,0,1}
		     ServerName = string()
		     Pid = pid()

	      Use this function to start WebTool if the  default  port,  ip-number,servername  or
	      path can not be used.

	      Path  is	the  directory where the mime.types file and WebTool's own HTML files are
	      located. By default this is webtool-<vsn>/priv , and in most cases there is no need
	      to change this. If Path is set to standard_path the default will be used.

	      If  Data	is  set  to  PortNumber  ,  the default data will be used for ip-number ( ) and server name ( localhost ).


	      Stop WebTool and the tools started by WebTool.


	      Types  Module = atom()

	      Debug a WebTool application by tracing all functions in the given module which  are
	      called from WebTool.


	      Stop the tracing started by debug_app/1 , and format the trace log.

       The  following  callback  function must be implemented by each web based tool that will be
       used via WebTool. When started, WebTool searches the Erlang code path for *.tool files  to
       locate  all web based tools and their callback functions. See the WebTool User's Guide for
       more information about the *.tool files.

       Module:Func(Data)-> {Name,WebData}|error

	      Types  Data = term()
		     Name = atom()
		     WebData = [WebOptions]
		     WebOptions = LinkData | Alias | Start
		     LinkData = {web_data,{ToolName,Url}}
		     Alias = {alias,{VirtualPath,RealPath}} | {alias,{erl_alias,Path,[Modules]}
		     Start = {start,StartData}
		     ToolName = Url = VirtualPath = RealPath = Path = string()
		     Modules = atom()
		     StartData = AppData | ChildSpec | Func
		     AppData = {app,AppName}
		     ChildSpec = {child,child_spec()}
		     See the Reference Manual for the module supervisor in the STDLIB application
		     for details about child_spec().
		     Func = {func,{StartMod,StartFunc,StartArg}, {StopMod,StopFunc,StopArg}}
		     AppName = StartMod = StartFunc = StopMod = StopFunc =atom()
		     StartArg = StopArg = [term()]

	      This  is	the  configuration  function  ( config_func ) which must be stated in the
	      *.tool file.

	      The function is called by WebTool at startup to retrieve the data needed	to  start
	      and configure the tool. LinkData is used by WebTool to create the link to the tool.
	      Alias is used to create the aliases needed by the webserver. Start is used to start
	      and stop the tool.
