Hi all,
I would like to define a variable in a user module in such a way that this
constant would be available for all functions (also out of the module) as a
"hidden(you don't need to see it inbrowsvar), protected (should not be
possible to clear it, even with clearglobal )" global variable as soon the
module is loaded: do you have suggestions how to do it within scilab?
There is still no actual solution to protect variables against clear.
But you may do the following:
// Save that in set_constantes.sci and build a library with it, thanks
to genlib(), say constantes_lib
function set_constantes()
L0 = ""; L0 = who("local")
c0 = 299792458
avog = 6.022045e23
planck = 6.626176e-34
qproton = 1.6022e-19
L0 = setdiff(who("local"), L0)
execstr("["+strcat(L0,",")+"] = resume("+strcat(L0,",")+")")
endfunction
// In your scilab.ini/.scilab :
load(path_to_set_constantes_sci+"/lib")
// Where you need constantes:
set_constantes()
// Then use the constantes defined in set_constantes()
The main advantage with this is that you don't need to remember where
set_constantes.sci is stored (to exec() it).
But nothing is protected: neither the library, nor set_constantes(), nor
the constantes it defines.
--> clear avog
--> set_constantes()
--> avog
avog =
6.022D+23
