## Revision 1.46 2004/08/04 19:46:42 geraint
## Sorts components alphabetically (type:name) within the categories:
## internal ports, components, 0 junctions and 1 junctions.
##
## Standardising the order in which components are listed allows models
## built with different editors to interact correctly by separating the
## graphical information from the data which is required to build models.
##
## Revision 1.45 2004/04/07 12:17:43 gawthrop
## Handles new Fig header line.
##
## Revision 1.44 2002/05/25 09:23:47 gawthrop
## Self-naming components: name is mttTYPE or mttTYPE_2 ...
##
## Revision 1.43 2002/05/22 10:33:18 gawthrop
## Nameless components are now named according to type - replaces old
## mtt1 etc style.
##
## Revision 1.42 2002/03/26 12:05:27 geraint
## Escaped characters to eliminate awk warnings.
##
## Revision 1.41 2001/06/13 10:41:06 gawthrop
## Further changes towards aouto creation of lbl files.
## Prettified lbl files
##
## Revision 1.40 2001/06/11 19:43:50 gawthrop
## MTT is now much more sophisticated in generating lbl files
## Labels can contain maths
## Repetative components are now broken
##
## Revision 1.39 2001/05/09 08:50:02 gawthrop
## Uses _art.fig to transmit the art work to the cbg.fig rep.
##
## Revision 1.38 2001/03/23 14:57:31 gawthrop
## Now puts space after header fields + writes _port.fig
##
## Revision 1.37 2000/09/14 08:43:32 peterg
## Add additional directional informatiuon to rbonds:
## cols 7-8 Arrow end directional bond
## cols 9-10 Arrow end directional bond
##
## Revision 1.36 1999/11/19 04:00:26 peterg
## Changed a comment to be more accurate.
##
## Revision 1.35 1999/07/25 22:19:45 peterg
## Fixed bug with false objects when compound objects present.
## -- Reset object to 0 after processing text.
##
## Revision 1.34 1999/02/17 06:23:49 peterg
## Bugs arising from Fig 3.2 fixed
##
## -- depth now zero modulo 10 (3.2 defaults to depth 100!!)
## -- horrible bug using = in place of == fixed.
##
## Revision 1.33 1998/08/10 15:51:06 peterg
## Comments may now be prefaced by # as well as %
##
## Revision 1.32 1998/07/27 20:30:03 peterg
## *** empty log message ***
##
## Revision 1.31 1998/04/16 13:18:13 peterg
## Now ignores spurious ports (in lbl but not Figure \ref{) but gives
## warning
##
## Revision 1.30 1998/04/12 15:01:17 peterg
## Converted to uniform port notation - always use []
##
## Revision 1.29 1998/04/12 12:35:32 peterg
## Named and unnamed SS handled in a uniform manner - in particular, the
## attributes are passed through
## wrote_component function used.
##
## Revision 1.28 1998/04/06 08:41:48 peterg
## Fixed bug due to adding (and then removing) 0 and 1 as port types
##
## Revision 1.27 1998/04/04 10:54:58 peterg
## Remove a debugging print statement
##
## Revision 1.26 1998/04/04 07:29:26 peterg
## SS now only port component
##
## Revision 1.25 1998/04/03 15:07:20 peterg
## Now correctly write 0/1 port names
##
## Revision 1.24 1998/04/03 14:02:50 peterg
## Added 0 and 1 to list of possible ports
##
## Revision 1.23 1998/02/01 18:37:41 peterg
## Don't print irritating warnings about ports listed in lbl files.
##
# Revision 1.22 1997/08/09 14:42:39 peterg
# Added underscore to port regexp
#
## Revision 1.21 1997/08/04 12:49:17 peterg
## Modified to use named (as opposed to numbered) ports.
## Generates a list of component ports in the .rbg file.
## As octave handles string vectors properly, the .cmp file format is not
## really necessary - but I've let it be for the moment.
##
## Revision 1.20 1997/03/19 12:02:01 peterg
## Now writes an error message if a lable is used twice in the fig file.
##
# Revision 1.19 1997/03/19 09:49:39 peterg
# Ports now written in cmp file.
#
# Revision 1.18 1997/03/19 09:42:08 peterg
# Now writes out the following additional fig files:
# _head.fig The fig header
# _bnd.fig The bonds actually used
# _cmp.fig The components actually used.
#
# Revision 1.17 1997/01/02 11:21:17 peterg
# Now assumes all components bonds etc at depth zero in fig file.
# Ie anything at depth>0 is ignored.
# Thanks to Donald for suggesting this.
#
## Revision 1.16 1996/12/30 20:00:29 peterg
## Fixed bent-bond bug.
## NB unfixed problems:
## 1. xfig writes multi line fields if more than about 5 segments.
## 2. rbg2abg takes a multi-segment bond as a straignt line between the
## end points - so computation of stroke and arrow directions may be
## iffy.
##
## Revision 1.15 1996/12/30 19:23:35 peterg
## Allows for bent bonds - ie bonds with more than 2 line segments.
##
## Revision 1.14 1996/12/21 19:47:53 peterg
## Changed \* to \\*
##
## Revision 1.13 1996/12/21 19:47:23 peterg
## Put back under VC
##
# Revision 1.12 1996/08/24 16:30:12 peter
# Fixed error in nonport_regexp.
#
## Revision 1.11 1996/08/19 10:48:57 peter
## Added `-' to the component regexp.
##
## Revision 1.10 1996/08/19 09:03:13 peter
## Parses repetative components: ie suffixed by *n.
##
## Revision 1.9 1996/08/09 08:23:11 peter
## Fixed bug: ports not recognised.
##
## Revision 1.8 1996/08/05 20:12:43 peter
## Now writes a _fig.fig file.
##
## Revision 1.7 1996/08/05 18:44:56 peter
## Now writes out a _cbg file without ----- symbol.
##
## Revision 1.6 1996/08/05 12:17:37 peter
## n_ports now appear in the _abg file instead.
##
## Revision 1.5 1996/08/05 12:01:28 peter
## The _cmp function now returns the number of ports.
##
## Revision 1.4 1996/08/05 10:14:46 peter
## Made ports appear, in order, at top of component lists
##
## Revision 1.3 1996/08/04 20:32:28 peter
## Stopped complaint about missing lbl entry for port components
##
## Revision 1.2 1996/08/04 20:05:25 peter

# This (g)awk script reads a fig file in fig 3.1 format.
# It interprets the picture as: bonds, arrows and components
# as follows:
#
# Bonds are firm (not dashed etc) polylines with n line segments -
# fig represents this by a firstline record where
# field 1 = 2 (always 2)
# field 2 = 1 (polyline)
# field 3 = 0 (style is a firm line)
# field 7 = 0 (depth is zero [top level])
# field 14 = 0 (no forward arrow)
# field 15 = 0 (backward arrow)
# field 16 = Number of point in line (points=segments+1)
# a data field starting with a tab followed by points (x,y) cordinates
#
#
# Strokes are polylines with 1 line segment and and no arrow
# fig represents this by a firstline record where
# field 1 = 2 (always 2)
# field 2 = 1 (polyline)
# field 3 = 0 (style is a firm line)
# field 14 = 0 (no forward arrow)
# field 15 = 0 (backward arrow)
# field 16 = Number of point in line =2
# a data field starting with a tab followed by 2 (x,y) cordinates
#
# Arrows are polylines with 1 line segment and an arrow
# fig represents this by a firstline record where
# field 1 = 2 (always 2)
# field 2 = 1 (polyline)
# field 3 = 0 (style is a firm line)
# field 14 = 1 for a forward arrow
# field 15 = 1 for a backward arrow
# an additional data files
# a data field starting with a tab followed by 2(x,y) cordinates
#
# Components appear in two files -- the fig file and the lbl file
# these two files are concatenated with the lbl file first
# The lbl file represents components by 3 fields
# field 1 is the name
# field 2 is the CR name
# field 3 is the CR arguments
# The fig file represents components by 14 fields
# field 1 = 4
# fields 12 and 13 are the coordinates
# field 14 is the type:name string terminated by \001
# To prevent text being confused with components, components consist
# of alphanumeric characters and : and _ only.
#
# Components are sorted alphabetically ("type:name")
# within the following categories:
# 1) internal ports (SS:[...])
# 2) basic components, subsystems and external ports
# 3) 0 junctions
# 4) 1 junctions
