Test-keyword for single-line if-constructs

[eesau]

My code is riddled with small if-constructs like this:

Code: Select all

If SomeVariable
  CallSomeProcedure()
Else
  CallOtherProcedure()
EndIf

To shorten the source code and to make it more readable, I suggest we have Test (or IIf?), True and False -keywords, so that the above code would shorten to this:

Test SomeVariable True CallSomeProcedure() False CallOtherProcedure()

We could even evaluate just True or False like this:

Test ResultFromSomeProcedure() False Result=#False
Test BreakFlag True Break

you can use macros for this

I know, but they get messy, and need both truepart and falsepart. And parenthesis. I'd rather have a native solution.

The suggestions you made are not Basic programming.

Why not?

[PB]

Have you seen the majority of Basic languages using your examples?

[eesau]

No, but the features of other languages shouldn't be a reason to exclude features from PureBasic.

Test SomeVariable True CallSomeProcedure() False CallOtherProcedure()

If SomeVariable : CallSomeProcedure() : Else : CallOtherProcedure() : EndIf

You'd save only two characters by doing it your way. What's the point?

[eesau]

The point is readability.

And sexiness

[Kaeru Gaman]

readability:
I find "Test X True Y False Z" rather confusing in an BASIC environment.
... what is it, Perl or Lisp?

sexiness:
there are people out there (including me) who would prefer Aretha Franklin before Paris Hilton!

> The point is readability

Maybe for you. I find it totally un-Basic to read. Just use Macros and be done.

[fsw]

Maybe you mean something like:

IFF

The IFF Statement starts an IF FALSE test in an IF ... ENDIF block .

IFT

The IFT Statement starts an IF TRUE test in an IF ... ENDIF block .

IFZ

The IFZ Statement starts an IF ZERO test in an IF ... ENDIF block .

XBasic and XBlite have it for ages... how un-basic is that?
(btw XBasic is way older than PureBasic...)

Thinking of it, I mentioned it long time ago, but as usual nobody listen to me anyhow...

Here it is:

Horrible idea, but feel free to put it in your own macros

I'll stick to the cumbersome approach...

Code: Select all

If a = 1
  < do something >
Else
  < do something else >
Endif

Or...

Code: Select all

< do something else >
If a = 1 
  < do something >
Endif

I could imagine, for a one-liner, to use the Then keyword like this:

Code: Select all

If a=1 Then b=3 Else c=5

And it is Basic-like

[Dude]

Code: Select all

If a=1 Then b=3 Else c=5

But the above can already be done like this:

Code: Select all

If a=1:b=3:Else:c=5:EndIf

With just one single character difference in typing length.
