Printf the hard way

• I just found this in some vendor-supplied demo code. Language is Delphi (pascal). I've kept the original indenting, line spacing and non-existent comments (modulo Community Server behaviour).

``` function HexWrdToStr(Dval : integer) : string; var i : integer; retstr : string; begin retstr := ''; i := (Dval AND \$F000) DIV \$1000; case i of    0 : retstr := retstr + '0';    1 : retstr := retstr + '1';    2 : retstr := retstr + '2';    3 : retstr := retstr + '3';    4 : retstr := retstr + '4';    5 : retstr := retstr + '5';    6 : retstr := retstr + '6';    7 : retstr := retstr + '7';    8 : retstr := retstr + '8';    9 : retstr := retstr + '9';    10 : retstr := retstr + 'A';    11 : retstr := retstr + 'B';    12 : retstr := retstr + 'C';    13 : retstr := retstr + 'D';    14 : retstr := retstr + 'E';    15 : retstr := retstr + 'F'; end; i := (Dval AND \$F00) DIV \$100; case i of {same 16-line case as above} end; i := (Dval AND \$F0) DIV \$10; case i of {same 16-line case as above} end; i := Dval AND \$F; case i of {same 16-line case as above} end; HexWrdToStr := retstr; end; ```

That's 84 lines and some very untidy string manipulation, and there's a similar one for bytes. Yes, Delphi does have a printf equivalent.

•  Or, of course, you could use the built-in IntToHex() function

That's the one !

A secondary WTF is that they're in a unit where they have no relationship at all to the the unit's function (which is a wrapper to a dll). They're only used in the mickey-mouse demo app, so if he had to have them why not just dump them in with the rest of the app code? I've just written a component based on this guy's library, and now I discover that that also is crap and I have to write my own library as well. [/rant]

Sounds like a case of Developmenstruction to me.

You were surprised? If I had found that piece of crap, I would have assumed everything else written by him crap as well.

I tried the library first, then investigated the code when the problems arose. In fairness, this vendor's core products are excellent, I think this demo was thrown together in a hurry, possibly by someone not too familiar with Delphi.

I doubt it's even that.

I'm pretty sure calling a demo a micky-mouse demo makes you a furry.

You say that like it's a bad thing ! In UK English, applying the term 'mickey-mouse' to something suggests shoddiness, unfitness for purpose, or similar connotations.

Indeed, but only God knows why!

Well, He should do. God is an Englishman, after all.

No she's not
