Operator len() can be overloaded; a non-member unary operator declared/defined outside of the type in the global namespace. Thanks, that clears the fog. I think generally speaking, its better to state "what it is", instead of stating "what it isn't". Seems far easier to understa...

@coderJeff, thanks for your clarifications. The static Operator, seems to be, what I'm looking for. However, the expectation on the 'to be obtained result ' is different than yours: ... Dim As T x Print Len( x ) ' <---- no type prefix This seems to mean, that your question: Maybe it should be added ...

@srvaldez,

please, read it all, again ...

I'm not a fan, of repeating myself. ;-)

Sorry, the error # was too low (by 10) ...

FbTemp.bas(33) error 153: Operator cannot be a member function (TODO), before '(' in 'Declare Operator Len() As ULong'
FbTemp.bas(33) error 153: Operator cannot be a member function (TODO), before '(' in 'Declare Operator Len(ByRef As zstr_t) As ULong'

First how exactly do you define a "match"? E.g. all three elements are of equal content? In principle, there are no such "specific" language constructs in FB. (unlike, e.g. VB.NET) The way to deal with such "specifications", should be split into: 1) load everything (fro...

1) Current behaviour doesn't allow, a differing implementation of String . 2) Len() is a crucial part of that. 3) Unary / Binary / Ternary Operators in types, are in principle possible. (e.g. + or & overloaded concatenation Operators (unary)) 4) The received Error: 143, clearly states (T...

As written: Operator Len() ... (first noticed). (the return type of a function is not taken into account for overloading) does NOT apply there. Operators can differentiate on return type only (Operator specific behaviour). It's not really helpful, to concentrate on "heavily simplified code"...

I've noticed at first, when trying a customized string-type, which was to contain a overloaded Operator Len() (unary operator overload) as per description in doc. It gave a Error, in which it was stated, that this is on the TODO list. In the light of the recent discussion on WString (making it dynam...

Yes, WIN-API code can do it (but, the code is no longer multi OS).

If multi OS is the intention, you'll have to use a external lib.

Seems that you are somewhat confused, since a Double (FB or C, ...) is a defined quantity, in terms of being 64 bit / 53 bit mantissa (52 + 1 implied), as defined by: IEEE 754, binary64 . (in FB/C called: Double) Therefore, Double in FB = Double in any other language, the Name can be different (the ...

I tend to agree with speedfixer, use option #1. (preferred) Also, just providing ' primitives ' like required Macro's and such, should do. Extending the 'primitives' according to the ' job at hand ', by the application developer, at the sole discretion of the programmer in question ... I'd strictly ...

@dodicat,

file is small: 2.53 MB only, otherwise, all okay. (FBC 64, 1.06.0, Win standalone)

This feature enabled, my life is easier ;) What makes you think so? I don't see any reason for it. 'Var bar = 67.2f ' forced to: Single Var bar = 67.2 ' default Double #Print TypeOf(bar) ' see: compiler output Print bar : Sleep TypeOf() returns the data-type, as string at compile time.

Thank you.

When the data are referenced by a pointer, alone or within a descriptive structure (a UDT, for example), it is usually best to only SWAP only exchange s the values of the pointers or the contents of the descriptive structures without accessing data themselves. This part needs a reformulation, a sta...
