Re: [OctDev] emacs macro for 2.1.39 adaptation

[Etienne G. <et...@is...>]

  Hello,

the intent was to facilitate the transition and make clear what was
changed and what is new. If bugs appear, one can check that the new
and old code really do the same. I was tagging lots of code by hand
and I found the macro useful.

  Cheers,

  Etienne

# To support the TSA toolbox, the preprocessor should also be able to test

# How about:
# 
# 	%function foo (...)      %# pre o2.1.37
# 	function foo (varargin)  %# post o2.1.37 or post m5.0.0
# 	%function foo (a1,a2,a3,a4,a5) %# pre m5
# 
# Or if you don't want to bother with Matlab 4 support
# 
# 	%function foo (...)      %# pre o2.1.37
# 	function foo (varargin)  %# post o2.1.37 or post m0
# 
# We don't have to write the preprocessor now, but it would be nice to
# nail the syntax.  
# 
# Call it with 
# 	mprep o$OCTAVE_VERSION *.m
# or
# 	mprep m$MATLAB_VERSION *.m
# 
# 
# So version is nameMajor.Minor.Patch, and we need pre, post, and, or
# 
# We could let name be the null string for octave.
# 
# Thoughts?
