Hi,

In a testsuite I want to test functions written originally in matlab.
One of them contains a line "lighting phong;". This line produces an
error under Octave2.9.x:

    >> lighting phong;
    parse error:

      syntax error


How can I write a mock function to make Octave 2.9.x ignore this line?

In my testsuite I use something like this to ignore a set of GUI
functions:

   if any(which('OCTAVE_VERSION')) && strncmp(OCTAVE_VERSION, '2.9', 3)
        disp ('adding ''octavefun/'' containing wrappers');
        %%% update dispatch table
        if ~exist('findobj'), dispatch('findobj',
strcat(pwd,'/octavefun/findobj.m', 'any')), end;
        if ~exist('gca'), dispatch('gca',
strcat(pwd,'/octavefun/gca.m', 'any')), end;
        if ~exist('gcf'), dispatch('gcf',
strcat(pwd,'/octavefun/gcf.m', 'any')), end;
        if ~exist('get'), dispatch('get',
strcat(pwd,'/octavefun/get.m', 'any')), end;
        if ~exist('jet'), dispatch('jet',
strcat(pwd,'/octavefun/jet.m', 'any')), end;
        if ~exist('lasterror'), dispatch('lasterror',
strcat(pwd,'/octavefun/lasterror.m', 'any')), end;
        if ~exist('lighting'), dispatch('lighting',
strcat(pwd,'/octavefun/lighting.m', 'any')), end;
        if ~exist('rotate3d'), dispatch('rotate3d',
strcat(pwd,'/octavefun/rotate3d.m', 'any')), end;
        if ~exist('set'), dispatch('set',
strcat(pwd,'/octavefun/set.m', 'any')), end;
        if ~exist('uicontrol'), dispatch('uicontrol',
strcat(pwd,'/octavefun/uicontrol.m', 'any')), end;
        if ~exist('uimenu'), dispatch('uimenu',
strcat(pwd,'/octavefun/uimenu.m', 'any')), end;
        if ~exist('what'), dispatch('what',
strcat(pwd,'/octavefun/what.m', 'any')), end;
        if ~exist('x_addpath'), dispatch('x_addpath',
strcat(pwd,'/octavefun/x_addpath.m', 'any')), end;
    end;

In octavefun/ there are my mockfunction, pE. "gca.m":

    function ret=gca(varargin)
    ret = [1]
    disp('<-- gca');


But how can I write a mock for "lighting", so that the line described
on top will not fail in Octave 2.9.x?

Any hints?
