I am glad you said that with a smile, but of course you are absolutely right.
Fortunately, that situation is improving.

Modified Files:
      Tag: SHADE-EXCLUSION
	x16c.c 
Log Message:

This is a commit in the SHADE-EXCLUSION branch.  The modifications here
allow a smooth boundary to be drawn when exclusions are specified for the
plshade routines, instead of the jagged boundary we currently have in demo
c16c.c.

The API of plshade has been changed, in particular the new type of the
"defined" parameter, which is now:

    PLINT (*defined) (PLFLT, PLFLT)
    
instead of:
    
    char *defined

This breaks the C++ bindings, besides causing a potential breakage of old
user code.  Furthermore, I disabled the other exclusion mechanism, based on
the values of sh_min and sh_max.  This also can have some undesirable
effects for the users.

This changes will be sitting in this branch until either Maurice or me will
have time to get back to the breakage issues.

I hit the return button too early. After that I corrected the log=20
message (using "cvs admin") to read as follow:

I applied the above message to revision 1.1 instead of revision 1.2=20

Make ninth C example consistent with python example.  (No real change to

There are some tiny visual differences between the two results for the ninth

don't really understand the origin of these differences, but I suspect we
are the victim of a nasty coincidence so that some of the pen strokes for
this example pass virtually exactly between two pixels, and the decision
about which pixel is painted rests on the last few bits of double precision
which are different in the two front ends.  I did print out a variety of
values between the two front ends.  They are consistent to 16 figures.  I
also did a lot of code inspection, and I am reasonably confident that the
two front ends are floating-point consistent to this level.  It is just for
certain examples that even this level of consistency is not good enough to
produce the same postscript plot because of the above "nasty coincidence"
argument.

respectively to ifcc of 0 and 1) which I preserved, but Joao may want to
change this to use the native plpoly3 rather than his special version.)

The C, tcl, python, and octave 18th examples (which all call plpoly3
directly or indirectly) give identical results which is a good test that
the API changes have been done in a consistent manner.

Log Message:
Make plGetCursor() return the subwindow (alias subpage) number.

This might not give the expected result on all plots, if several subwindows and
viewports are set.
Also, for real multi-window (frames) apps, the user must use plgstr() to get
the current stream number, as the subwindow number is set to 0 for each new stream.

Log Message:
Restore "minor" changes in title, title colour, and order of plplot commands
to previous values. 

I am reverting this part of the previous change because I don't think it
made any obvious improvement (in fact I preferred the previous versions in
any case), and also it is extremely important from the testing perspective
to maintain consistency as much as possible with example 8 for other
interfaces (once those other example 8's are upgraded to also use plotfc3d).

That said, I am willing to change all other python, tcl, java, and yorick
examples to be consistent with any *important* improvement to C examples
(such as plotfc3d).  But it is a fair amount of work to keep this
equivalence of the examples maintained so please be careful of what you do
change in the C examples.

Replaced

Using LDADD instead of AM_LDFLAGS is the Right Way (TM) of doing things,
because the dependencies are generated correctly.  AM_LDFLAGS should only be
used to pass _flags_ to the link command, not library objects.

This reminds me that there are several other places in the source tree that
have the same problem.  They will be fixed progressively.

This commit also changed "../.."to "$(top_builddir)" in the definition of
the variable libplplot.  Again, this is the Right Way with Automake, since
it is more robust to eventual reorganizations of the source tree (okay, that
is not likely to happen with PLplot, but let us act in a principled way).

Log Message:
Sane treatment of DATA_DIR and DRV_DIR

The variables/#defines DATA_DIR and DRV_DIR are treated now in a more
coherent and Autotools-friendly way.  The main changes regard:

    - Use of $libdir and $datadir as prefixes of DRV_DIR and DATA_DIR,
      respectively, in configure.ac.  This allows users to easily override
      the installation locations when running configure (options --libdir
      and --datadir).  The environment variables DATA_DIR and DRV_DIR are
      still honored.
      
    - DRV_DIR is an absolute path now, not relative to DATA_DIR as before.
      Besides it being cleaner and more intuitive, the new design allows
      better compliance with the FHS.  Indeed, architecture-independent
      files (like the font amd map files, as weel as examples and the Tcl
      stuff) go by default in $prefix/share, while driver module files
      (which are architecture-dependent) go in $prefix/lib.
      
As regards final results, the only difference with the previous situation is
that the *.fnt and *.map files are installed now in plplot<version>/ instead
of plplot<version>/data.  I did not try to keep the previous situation
because it would imply in the definition of a new variable/#define.
However, if the other developers have really strong arguments in favor of
it, I will implement that.

Log Message:
Use pkg-config in examples/*/Makefile.examples when appropriate

   - Makefile.examples are now under Automake control.  This means that
     Makefile.examples.in are removed from the CVS repository and replaced
     by Makefile.examples.am.  The Makefile.examples.in are automatically
     generated by bootstrap.sh (no change to the script was needed for
     that).

   - In the Makefile.examples.am, the rule to build the examples look
     like this:                                                           
               
     .c$(EXEEXT):
     if have_pkg_config
             $(CC) $< -o $@ `pkg-config --cflags --libs plplot$(LIB_TAG)`
     else                                                                
             plplot_libtool --mode=link $(CC) $(CFLAGS) $< $(INCLUDEANDLIB) -o
+$@
     endif

   - The AM_CONDITIONAL have_pkg_config is exercised in configure.ac and
     will be "true" when the pkg-config program is found in the system. 
     Also, there is a configure option --without-pkg-config (or        
     --with-pkg-config=no) that will disable the use of pkg-config and
     fallback to plplot_libtool.

Modified Files:
	Makefile.examples.in 
Log Message:
Fixed several issues related to the *_DIR variables

* Made the treatment of the *_DIR even more systematic now.  These variables
  are really intended to AC_SUBSTitution in the Makefile.in generated from
  Automake.  As such, they are always relative, never hard paths.
  
* When it is needed to get them substituted as hard paths (like in config.h
  via AC_DEFINE_UNQUOTED, or in the examples/*/Makefile.examples), then new
  variables are defined.  In particular, this is the case of the new
  variables INCLUDE_DIR_CMD and LIB_DIR_CMD, which should be used in
  examples/*/Makefile.examples and fix the problems with the plplot_libtool
  approach.
  
* In order to help expansion of hard paths, the macro EXPAND_EXPRESSION was
  added to acinclude.m4.
  
* Support for pkg-config was added to examples/tk/Makefile.examples.in.
  Build of the examples in examples/tk with pkg-config is not working yet,
  though.  The Tcl/Tk include directories are not being included.  I will
  fix this later.

Update of /cvsroot/plplot/plplot/examples/c
In directory sc8-pr-cvs1:/tmp/cvs-serv29624/examples/c

Modified Files:
	Makefile.examples.in 
Log Message:

* Created the AC_SUBSTituted variable PKG_CONFIG_ENV. This variable replaces
  the previous PKG_CONFIG_PATH.  It defaults to the usual
  "PKG_CONFIG_PATH=$PKG_CONFIG_DIR", but can be overriden by using the
  environment variable of same name.  This is done in debian/rules for
  instance , since setting PKG_CONFIG_PATH is not necessary in Debian.  The
  echo from the make command in the installed examples directories is much
  cleaner now (in Debian, at least):

      $ cd examples/c
      $ make -n x01c
      gcc x01c.c -o x01c  `pkg-config --cflags --libs plplotd`


* Added $(RPATH) to the compilation command under the pkg-config approach in
  the examples/*/Makefile.examples.in.


* In examples/tk/Makefile.examples.in, added include flags specific to
  Tcl/Tk in the compilation command under the pkg-config approach.  A new
  variable TCLTKINCCMD was created, which is also used in INCLUDEANDLIB.

Log Message:
Fixed use of rpath option in compile commands under the pkg-config paradigm.

A new AC_SUBST variable RPATHCMD is created in configure.ac containing
"-Wl,-rpath -Wl,$libdir".  This solution has portability issues, but should
work now for a large spectrum of systems/compilers.  I will revisit this
issue in the future.

Log Message:
This jumbo cvs commit is the result of a herculean task to update the
copyright notices of most of the source files of PLplot.

I hope that I did not introduce any serious breakage.  This seems plausible,
because I did changes only at the beginning of the files and only in
commented lines.  However, I used a semi-automatic procedure for doing that
and some bugs may have slipped into the files.  The sources still build okay
(at least the Debian packages) and I can install the libraries, and compile
and run some C examples.  That is not enough, so PLEASE TEST!

This is what I did in more detail:

1) From the CVS ChangeLog, I considered all the files that changed since the
   last release (5.2.1).  I then added the line:

       Copyright (C) 2004  Joe C. V. S. Committer 

   where the name of the developper who did the CVS commit is included.
   
2) Notice that the year in the line above should read 2004, even if the
   changes were done last year, since Copyright years refer to when the
   software is released.
   
3) For the same reason, I did not bother adding missing Copyright entries
   for previous authors of each file.  One copyright holder is enough for
   our purposes.

4) I also reformatted and reworded the License Conditions text.  This
   included changing things like "This file is free software" to "PLplot is
   free sofware" and so on.
   
5) Finally, some files were lacking License notices, especially the src/*.c.
   I added them and put in the Copyright holder line the name of the
   developer who did the last cvs commit for the file.

If you wish to know where your name appears, you can run from the
$(top_builddir):

    grep -ri "copyright.*2004".
