Control Globals and functions renaming

I'm a little confused with the readme file.
If I use the renameGlobals=true parameter, it renames globals, and functions. ok.
If I have a function that is called from another script, the call is broken. ok.
So I have to exclude it from the renaming list with reservedNames. ok.

The problem is that doing this, it is not obfuscated.
Is there a way so I can rename it, at obfuscation, without touching the source code ?

For example, saying that this string THISFUNCTION, should always be renamed with this TiHiIiSiFiUiNiCiTiIiOiN or with ghfdffgfhdfjghdfgjdsfhgf when obfuscated.
This way, when I obfuscate any script, I can keep the function call by maintaining some coherence.
Same thing for globals.

note that THISFUNCTION can be a function name, and of course a string corresponding to a javascript call.

    SCRIPT 1 : function THISFUNCTION() {}
    SCRIPT 2 : <input type='button' onclick='THISFUNCTION();' />

The solution is to implement name cache like uglifyJs and terser are doing.

Was this ever completed ?

In the future. Right now I have other priorities.

Okay, is there a known workaround ?

only with reservedNames

Returning a Map with the old function/vars => new obf functions/vars would allow us to come up with potential alternatives

I will implement names cache (that writes into the file) in the future (like uglify.js does) but i haven't any date. Sometime in next year.

I think, i have to implement this as the next big feature.

hmm, that means what we can do something like REPLACE function inside obfuscator?

Like:

// config
{
"identifierNamesCache": { _date: new Date() } // just example, mb I wrong 
}
// code 
const date = _date; // _date is not defined, but should be replaced by "new Date()"

With

"identifierNamesCache": {
     "globalIdentifiers": {
         _date: new Date() 
    }
}

You can do this, but this is not the expected use case for this option (because I limited globalIdentifiers usage to undeclared variables.
If sometime in the future I will add the way to control identifier names, it will the way through identifierNamesGenerator option.

Tested, that work now

The empty option object now should work correctly

ReferenceError: Validation failed. errors:
`identifierNamesCache` errors:
    - Passed value must be an identifier names cache object or `null` value

    "identifierNamesCache": {
        "globalIdentifiers": {
            "KRUZYAPIDOR": true
        },
        "propertyIdentifiers": {}
    }

did that bug? 👀

I was try do like you say - #629 (comment)

No. Dictionary values should be strings.

yep, work now.

That all or we should test anything more?

@sanex3339

@sanex3339 for use this like replace in code, we should add second obfuscate (or obfuscate only replaced values) or we get unobfuscated values, functions and etc.

All replaced values won't be obfuscated. So as I said before this use case is not an expected use case.

yep, I now. I mean, if we add feature for replace code as expected, we also should add obfuscation for replaced values
or we have second choice - obfuscate values before inserting for replace.

I don't know how i will do this right now. Right now this is the cache only for reuse some names between files

Thank you for testing. Probably from tomorrow and all this and partially next week I won't be able to finish this PR, because of my vacation. I'll finish in a week.

Why not? Released as 2.14.0. Enjoy! For any bugs, please create a new issue
