arcticir,
You don't want to use IsObject() a lot? Then don't.

Code: Select all

HU.INI := IniToObj("hy.ini") || {}

locale := HU.INI.HY && HU.INI.HY.locale || "EN"

Run, % (HU.INI.Browser ? HU.INI.Browser.Chrome || HU.INI.Browser.Opera : "") " " (HU.INI.ip && HU.INI.ip.google || "www.google.com")
It's shorter than before...

You could write it exactly as before, but override __Get so that HU.INI.whatever always returns an object. If the INI file doesn't exist, have IniToObj() return an empty INI object.

There's nothing to stop you from changing the error behaviour yourself, if you don't mind sacrificing compatibility with other scripts/code. You can still override the default base object's meta-functions.

Thanks.

but it could have been more succinct:

Code: Select all

locale := HU.INI.HY.locale || "EN"


Is it possible error As an alternative option,Such as voting results?
I believe most people like me do not need this feature
While we want AHK more rigorous,Think is an improvement
But more often we need to write code easily.
Prevent rigorous Become a burden。

Yes, see

Then could disable it or handle error (when access a string as object ) by themselves.
I think to skip the error is fine, maybe user only want to determine it from the last result (not in every step ).

Relative : V2 garbled data using default base (Default base used for skip and log 'no object to invoke' error.)

I regret, why not choose the voting result. :(
