We have operator "=" to Set a variable.

What I often wish is a short form as "Set-Append operator" ("=." is just an example): OK: just sometimes the reverse, "Set-Prepend": It's just to save some typing, and some space in the lines.
(With indentation etc lines can be rather long sometimes. Shorter looks better. )

nice to have (at least) these as well : +=, -=, /=, \=, *=

Ha: just created some text - but Sammay has edited his text and I didn't notice Quite funny
Though I'm late: my prepared post

Just to say: this could also be used for add, subtract, multiply and divide, eg =+, =-, =* and =/
(=+ and =- would be analog to incr, but I'd prefer the syntax of =+)
(OK: to inverse the operand for subtraction and division can be 2 more versions.)
Basically I'd prefer the = on left, can be read as "set to concationation" or "Set to sum".

Though: my main use and interest is just concatenation, as I really use it very often.

And to say again: to use =. is just an example - you might have other Ideas. But containing the = shows that it's relative to the set command.

Just had a laugh

So if I did explain it bad - I'm just looking for the same as the VB operator &= does.
Found it via a link to VB-docs from klownboy: thanks for that!

And I'd really use it very often. Again and again...

Yeah, me too, so +5

Code: Select all

   $listitems =. $entry;         // meaning:
   $listitems = $listitems . $entry;

OK: just sometimes the reverse, "Set-Prepend":

Code: Select all

   $listitems .= $entry;         // meaning:
   $listitems = $entry . $listitems;

Never heard about "Set-Prepend". In PHP (XY's role model) it's like this:
Anyway, I always planned to add these operators, so hey-ho let's go!

BTW, I personally never liked the sequence .=, I find =. more natural. I'm inclined to allow both ways...

That's fine! Hey!

"Set-Prepend" was just another idea, so: says "Hello John". (Sometimes I must build a string right to left.)
But no question: what you've made are the most often needed expressions.

You said you "Experimentally added ... Compound Assignment Operators .=, +=, -=, *=, /=, \= ."
What's the experiment?

For completeness: just changed one script to contain several .= seems to work fine!
Not just simple concatenations, but a bit more complex like:

So thanks a lot!

Nice!, even my meager scripting abilities will benefit from this, thanks.

Well, I was a bit surprised how easy it was to add it, so I added "Experimentally" as a voodoo-kind of protection against a rude awakening. Like when you take the umbrella along in order to prevent the rain -- usually works well.

Fine, that quite some scripters seem to be glad.
Fine, that it was easy.
Fine, that the voodoo seems to help.
Best of all, that you were surprised

So: all is well

Have a fine Sunday!
(I hope you like it cold.)
