AutoHotkey Community

I have found that AHK runs hand in glove with the basic dialect I use which is Rapidq.
I am pleased that it seems a mixture of c and basic with simple english commands.

It is this mix that I find confusing sometimes and the documentation although a massive work in itself often does not explain simple concepts
for instance adding two strings
in basic this is simple. I have found a way in AHK but
a = abc
b = def
c = a + b
msgbox c ; should = abcdef
it works this way
a = abc
b = def
c = %a%%b%
msgbox %c%

works but not logical >>>I wish!

Your subject is useless...it should be...

plus (+) should be concat(enation)

...but in any case...

Plus = Concat - Post 1
Plus = Concat - Post 2
Plus = Concat - Post 3
Plus = Concat - Post 4

...I AGREE...

Indeed, I wish you change this subject...
It is like people putting "Help me" as subject in the Help section.
We haven't seen "My Script" in the script section (I didn't, at least), but it is in the same spirit...

Note: You have c = %a%%b%, but also c := a . b, so it has a real concatenation symbol already, no need to change it.

Yes, we already have the concatenate operator, and I think that's better than overloading the plus (+) symbol. Unlike some other languages that use it for concatenation, AutoHotkey implicitly converts strings that contain a representation of a number into the number itself:

Which of the two cases above should '+' perform when both the strings are purely numeric? It's ambiguous, because of AHK's weak typing.

Besides, even without the ambiguity, why not have a separate operator for it? There's much less potential for confusion that way, especially for beginners who may not find '+' as concatenation to be very intuitive.

Thanks for heads up you'r right about subject and I have changed it Sorry

It will take me a while as I easily reach for the + as I have gained bad habits not all related to scripting

Thanks for comments especially yours jonny. The others well! I stand corrected.

...yes, AHK should receive "typing"...in one of my concat posts I made an example of it...ok I can't find the post, so here...



...because!...ok not a good enough reason?...well because! anyway...I like plus...I don't care if dot stays, but I want plus for strings too...


...I don't see how using plus as concat is a "bad habit"...you are adding strings together, so + = add...you don't "dot" strings together...

No, you are not adding them, you concatenate them, that's not the same operation. Or why is there a separate word?
Adding two string should be something like:
No? With perhaps some constrain on printable Ascii...

When I add 1 and 1, I don't expect to get 11... (10, at worse )

I expect to get 0 with the overflow bit set.

I prefer space as concatentation and to leave . for something kewl, like pseudo - classes.

Like, StdLib.MyFunction(...)

or for struct support: myStruct.myField := 4

Well, this can be done even now as "." is not concatenation but " . "

It will be confusing though...

Wasn't this already discussed? Space as concatenation is horrible programming practice, mostly because it increases the chance of errors, but also because of ambiguity (not logical so much as visual). It doesn't even make much sense: an expression is not a specification for the construction of a string, it is a series of operations that may include data types ranging from numerical to boolean to textual.



Actually, it can't, '.' not being a legal character in a variable name.

Also, the space padding issue should be seen to fairly soon:

You sticks your toe in the water and the sharks bite.

I must say I do appreciate this. I am a concatenation of knowledge now.

What about a concat assign operator?

we can keep it


I didn't mean NOW, like NOW, but NOW like, AHK can be upgraded NOW to treat . as namespace delimiter as it can not be used in variable names and sentence Namespace.Variable is not valid in concatenation context...

Ah, I see. However, ideally Ident1.Ident2 would work (as concatenation).

No...
