Is it possible to avoid this jaggeg effect for fonts and pictures ? https://i.imgur.com/agzzanj.png testing https://github.com/hako/lines

@GiuseppeChillemi
@9214 @toomasv Thanks for you help
Now I have more knowledge about working of RED VID.A special thank to @toomasv as I am building from your code.
Now another request:
GiuseppeChillemi
@GiuseppeChillemi

Is I have a list like:

button-list: [field1 "aaa" field2 "bbb" field3 "ccc" ]

How could I dynamically create a GUI with those 3 fields ?

Somethig like:

Red []

view/no-wait [
    field1: field 70 hint "aaa" [probe face/text]]
    field2: field 70 hint "bbb" [probe face/text]]
    field2: field 70 hint "ccc" [probe face/text]]
]

@GiuseppeChillemi
list: [field1 "aaa" field2 "bbb" field3 "ccc"]

view collect [
    foreach [tag text] list [
        keep compose [
            (to set-word! tag) field 70 hint (text) [probe face/text]
        ]
    ]
]
GiuseppeChillemi
@GiuseppeChillemi
@9214 another lesson to study !
Keep and Compose are the target
I don't understand the reason for to set-word! Tag instead of Tag
Vladimir Vasilyev
@9214
@GiuseppeChillemi well, remove to set-word! and check how the output of collect changed with probe.

@GiuseppeChillemi
We are inside a dialect so I expect the code to be text
Vladimir Vasilyev
@9214
We are not inside a dialect.
GiuseppeChillemi
@GiuseppeChillemi
No ? Isn't the generated text passed to vid with view ... ?
(could try Tomorrow)
Vladimir Vasilyev
@9214
Then I don't get what you mean by "I expect the code to be text".
GiuseppeChillemi
@GiuseppeChillemi
I expected the "view" argument to be text. Then the dialect code interprets It.
Vladimir Vasilyev
@9214
It's not a text, it's a VID block which collect returns.
GiuseppeChillemi
@GiuseppeChillemi
Like "sell 10 shares at 50"
Ok, so we are parsing a block instead of text

@nedzadarek
@lepinekong_twitter as fair I remember, he said to check help for while and if. You can see that if takes cond [any-type!] and while, cond [block!].
If you are new (or used different languages) you may be confused about usage of () and []. An expression inside() is evaluated (e.g. a: ( 1 + 2) a; 3) and an expression inside [] is not evaluated (not sure if this is proper term). So you should use () for grouping code to run it immediately. You should use [] to pass some code/data.
ps. helps for both functions are wrong about true. It should be "true-thy value" or something like this.
ps2. I was very succinct about this description - I could miss something. I just didn't want to confuse you with unnecessary things.

I have a VIEW button which uses as DATA an "area" name, referencing the whole object ( @toomasv , yes, it is based on your code). If I define the area BEFORE the button in the VID BLOCK, everything works fine. If I define it AFTER the word is undefinied at runtime. Is it correct ?
Vladimir Vasilyev
@9214
@GiuseppeChillemi you can't directly reference something that doesn't yet exist.
view [
    b: button extra 'a [probe get in get face/extra 'text]
    a: area "this is an area text"
]
GiuseppeChillemi
@GiuseppeChillemi
@9214 Being a dialect it is different than the main program code loading...
Vladimir Vasilyev
@9214
@GiuseppeChillemi not really.
GiuseppeChillemi
@GiuseppeChillemi
I am used to define object at the botton of the code and being able to access it since the very first lines...
@9214 I could understand this but changes the coding schemas you have in mind.
Vladimir Vasilyev
@9214
@GiuseppeChillemi you can't do that directly, without storing referring words in a block or using lit-word!s instead.
GiuseppeChillemi
@GiuseppeChillemi
It is beacuse all objects are created and you can reference them ?
*is it beacuse all objects have already been created and you can reference them all ?
Vladimir Vasilyev
@9214
As I said, you can't reference something that doesn't exist.

I needed replace/all which is not in Red's version of replace, I tried Rebol's version (got from source replace), it works great, and it even allows to give a function as third argument. Any reason why this is not integrated in Red ?

@9214 Oh yes thanks. Now I will know where to make such remarks :)

@9214 A simple "" made me crazy....
I have a bunch of dynamically created buttons
Their face/data content refer to dynamically created areas objects

    foreach [tag name] buttons [
        keep compose [
            (to set-word! name) area 300x50 (copy "") wrap
      ]
    ]

The function executed when I hit one of the buttons pass the face/data, which is <areaname> ,and then I print <areaname>/text....

I always had the same printed result despite the button I hit....

Four hours to discover that tiny "" had to be changed to (copy "") !

Does anyone knows the Logo? You can play with it here.
I want to mimic Logo's functionality. What I need is to keep a) current pen position and b) rotation. shape sub-dialect keeps pen position but it does not know about rotation. I have found out that I can rotate over some point (rotate <degree> <point>). However I am rotating using values computed by me. Here is an example. I want to draw square.
The Logo code:

; just so we can start as Red's shape
right 90 

forward 40
right 90
forward 40
right 90
forward 40
right 90
forward 40

and here is the Red's code:

view [base 300x300 red draw [

  shape [ move 100x100 ]
  shape [ 'line 40x0 ] 

  rotate 90 140x100
  shape ['line 40x0]

  rotate 90 180x100
  shape ['line 40x0 ]

  rotate 90 220x100
  shape ['line 40x0 ]
 ]
]

Is there some function or word that keeps current pen position? I want to use it like rotate 90 _pen-position_ instead of hard-coded rotate 90 220x100.

Vladimir Vasilyev
@9214
@nedzadarek can't you just keep turtle's position and heading, emitting Draw code from compiler?
ne1uno
@ne1uno
relative position? '
Vladimir Vasilyev
@9214
@nedzadarek instead of mashing Draw code by hand, you can write Logo compiler/interpreter which will track turtle's coordinates with rotation angle and produces a Draw block automatically, by reading Logo commands.
nedzadarek
@nedzadarek

@9214

can't you just keep turtle's position and heading

Right! I'm too tired to remember most obvious things: shapes command uses end-point (pen position). So, as you said, I can just keep that 2 values.
Thank you.

GiuseppeChillemi
@GiuseppeChillemi
Is there any good Reading example in vid faces positioning ? I wish to have a Windows with Two orizontal Lines of buttons on the top, then a big area just below them on the left and many small areas spread vertically on the right. Each area should have a tittle just on the top of It.
I am going Crazy on this
