/* Consider the following a NOTES file:

   The main upshot of this is:
   * Plugins and Perl scripts (when I get round to signaling perl.c) can intercept text events and do what they like
   * The default text engine can be config'ed

   By default it should appear *exactly* the same (I'm working hard not to change the default style) but if you go into Settings->Edit Event Texts you can change the text's. The format is thus:

   The normal %Cx (color) and %B (bold) etc work

   $x is replaced with the data in var x (e.g. $1 is often the nick)

   $axxx is replace with a single byte of value xxx (in base 10)

   AGL (990507)
 */

/* These lists are thus:
   pntevts_text[] are the strings the user sees (WITH %x etc)
   pntevts[] are the data strings with \000 etc
 */

/* To add a new event:

   Think up a name (like "Join")
   Make up a pevt_name_help struct
	Add an entry to textevents.in
	Type: make textevents
 */

/* Internals:

   On startup ~/.xchat/printevents.conf is loaded if it doesn't exist the
   defaults are loaded. Any missing events are filled from defaults.
   Each event is parsed by pevt_build_string and a binary output is produced
   which looks like:

   (byte) value: 0 = {
   (int) numbers of bytes
   (char []) that number of byte to be memcpy'ed into the buffer
   }
   1 =
   (byte) number of varable to insert
   2 = end of buffer

   Each XP_TE_* signal is hard coded to call text_emit which calls
   display_event which decodes the data

   This means that this system *should be faster* than snprintf because
   it always 'knows' that format of the string (basically is preparses much
   of the work)
