How to declare global vars without id in *.upt?

I'm running out of space in the templates dialogue window... Smile

But, anyway, is it possible to declare extra global vars without using id's or, maybe in the worst case, to hide those fields?

Eh, now I am not quite sure what is your plan. What is "variable without id" ?

(Other than that, global variables are simply prefixed with ':').

My plan is simple: to generate some classes and methods depending on some entered numbers.
I've quite succeeded but I want to optimize more...

this code below generates: "func0 func1 func2" etc.

id "How many funcs" funcCount="5";

class blabla : staticRectangle {
public: 
<:{ x = ""; lim1=to_number(:funcCount); for(i = 0; i < lim1; i++) x<<"func"<<to_string(i)<<" "; return x; }:>
}

I want x to use like :funcCount somewhere below for other classes.

O maybe to have Esc functions? And send params?

Still not sure about that global bar (but global vars really just :id).

To define function, use <:!. See EscRun.cpp / Expand - that is the routine used to expant those .upt.

(BTW, there is quite a real power when using this Expand together with Qtf and Sql and RichEdit to generate documents based on templates (written in Qtf/Esc combo) that can be edited to the final form;)

I'm not against id's! Smile

But I don't want a field displayed for each of them. Is there a possibility without changing Template.cpp?

I think, I've tricked Esc and *.upt! Cool

<:!testf(){ return "testreturn"; }:> //declare a global function

<:testf():>   //this outputs "testreturn"

<:{ :testf=10; return;}:>  //make a global var from a function!!!

<:testf:>  //this outputs 10!!!

What can you say?

Well, you have not tricked Esc, this how it is designed. Lambda is value.

Maybe I am starting to get what is your confusion - you do not know how to "declare" global variable?

You do not need to declare variable in Esc, just to assign them.
Try:

<: :xxx = 10; :>

<: :xxx :>

<: :xxx = 10; :>

<: :xxx :>

If that worked I wouldn't have asked... Sad

Are you sure this works with *.upt?
For me it says #ERROR: missing :>

Can be a bug? Because it works like this:

<: :xxx = 10 :>

<: :xxx :>

Edit:
But, in this case, if I assign a number or a string Esc outputs them. Maps and arrays are OK.

Yes, sorry. <: is for expression, <:{ is for block of statements, that ';' makes it an expression.

What is wrong then?

BTW, strings are arrays, there is no difference. Also, maps are structures,

a.b

is same as

a["b"]

The problem is that if I assign to a global var a string or a number, their values are printed in the place of assignment. And that messes up *.h/*.cpp files...

Ah, of course, because if you do you <: :>, it is expression that gets evaluated and inserted. Use <:{ :global = ... ; }:> instead.

Thanks! That works!
I didn't manage to guess that when unsuccessfully tried this one (with spaces between <: and { ):

<: { :global = 10; } :>

Ech, those little things...

Anyway, Esc is PHP in Ultimate++! Very Happy

No, in fact this doesn't work. Could you check if this works for you? For me it says "invalid expression"...

Maybe it will require .... return ""; } :>.

If it does, Expand needs fixing.

Yes, your guess was precise... It works with return ""; ...
