Different data type possible in userconfig, how to handle this?

[tortuosit 485]

Hi,

I have the following code for reading userconfig file entries:

_t_trend = getText (configfile >> "TORT_DYNAMICWEATHER_Settings" >> "trend");

My problem: I want to allow different data types, i.e. string or array. _t_trend can be "blah" or [1,2,3]...

But with getText/getArray I already decide what data type it is, before the script can know... How do I handle this?

Hi,

Use "isArray" or "isText" for checked if the config entry represents an array or a text.

//_t_trend will always an Array

_t_trend = [];
if (isArray  (configfile >> "TORT_DYNAMICWEATHER_Settings" >> "trend") ) then
{
_t_trend = getArray (configfile >> "TORT_DYNAMICWEATHER_Settings" >> "trend");
};
if (isText  (configfile >> "TORT_DYNAMICWEATHER_Settings" >> "trend") ) then
{
_t_trend = [getText (configfile >> "TORT_DYNAMICWEATHER_Settings" >> "trend")];
};

Don't know if this is of any help to you but you can always play a wildcard by saving everything as string and then compile it. It's not nice but I do that sometimes, for example when I have multi-dimensional arrays saved in configs. (I know it's also possible to save them correctly in configs but it makes copy-paste operations easier and then there's my lazyness...)

Example - Config:

magazines = "[['30Rnd_556x45_Stanag', 10], ['16Rnd_9x21_Mag', 3], ['HandGrenade', 4], ['SmokeShell', 2], ['SmokeShellRed', 1], ['SmokeShellGreen', 1]]";

And then somewhere in my code:

_magazines = call(compile(getText(_class >> "magazines")));	
{_unit addMagazines _x} forEach _magazines;

Just a small hint, I'd go for TittErS' approach in your case.

Oh thanks guys, have overseen isArray/isText and IndeedPete, another interesting option, thx.

Now I remember, I once tried isArray, but it didn't work. This was only a scope problem, because without private statement _t_trend is only known inside the if-brackets...

Yes, either set it private or (if you know that it can only be array or text) you could also try:

_t_trend = if (isArray(configfile >> "TORT_DYNAMICWEATHER_Settings" >> "trend")) then {
   (getArray(configfile >> "TORT_DYNAMICWEATHER_Settings" >> "trend")
} else {
   ([getText(configfile >> "TORT_DYNAMICWEATHER_Settings" >> "trend")])
};

But isArray should work, I use it on a regular basis.

Yes I used if/else because it only can be array or string (or not available, which I'm to lazy to catch) :)
