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
view [
style small: area 30x30
button button button return
button button button return
area below small small small
]
area
I still have bit seen the result of your examples

Thanks for your help. I have just published the first working version: https://github.com/GiuseppeChillemi/textsplithelper.red/blob/master/TextSplitHelper.red

This my first ever code published on GITHUB.
I will use this software to catalog all my notes.
But has many other applications when splitting text lines to corresponding categories
(user defined inside the script, visually on newer releses)
@toomasv are you trying to draw a square and are you using my (edited) code? If yes then it should work for square because after each line we rotate by 90 degree so
<center> parameter ( (optional) center of rotation (pair!)) doesn't matter. We should calculate <center> parameter other way.
@nedzadarek Sorry, I meant that it looks rather like a bug. But on closer inspection it is clearly not a bug. :smile:
@greggirwin :+1: I have yet to understand syntax but it is not far from the Rebol/Logo.
You once mentioned the Logo. I thought I would try it as a programmer (I have seen it when I was young). It has very easy syntax but it is capable of doing amazing things, even by accidents. Non-programmers can learn how to program and programmers can use it for building fractals, space-filling-curves etc.
What do you think about extending

What do you think about extending
draw/shape of the Logo's features (rotation/heading, loops, conditions, functions etc)?
Right Mouse Button
Middle mouse Button
Wheel rotation ?

All the event names are listed here: event names - just remember that the name in the code block is ON-xxx where xxx is the listed event name.
Logo is almost just Lisp without the parens. Brian Harvey wrote a 3 volume series about it: Computer Science Logo Style.
You could easily compose things in that way for static drawings, but the real use of the turtle in logo was as a more interactive tool for thinking and learning.
Draw is static while watching the turtle move and draw is a big part of that experience, which means your Logo drawing commands are really tied to a timer of some kind. What we could do, then, is set a canvas face for the turtle commands, and as you run them, the draw block for that face would be updated, so the Logo part is in control there.
@lepinekong_twitter I see, that's what you mean. Let's take it from a different angle. You have
It's nice design choice. It tells you if the code will be run multiple times (or it will be passed as code/data).
while that checks a condition every time (before entering body block) and you have if that need to check it once. You need a block to run code multiple times so if doesn't need it.It's nice design choice. It tells you if the code will be run multiple times (or it will be passed as code/data).
; Hi, newby question about contexts. I want to be able to set values in the do-block of a button, but I'm
; got "word not bound to context" error:
f: function [] [
return view/no-wait [
button "test" [
x: "hello"
]
]
]
; -> error: word not bound to context
; I tried two workarounds, setting the values in an options block passed to face,
; and setting the values in a context, but I'd like to know if there is a way
; to carry out my original intentions using bind or something. I believe the
; error is something to do with anonymous functions in the dialect not
; having a context?
; Set data in face options
f: function [] [
return view/no-wait/options [
button "test" [print face/parent/data/x]
] [data: [x: 100]]
]
; set data in created context
f: function [] [
return context [
x: "hello"
init: view/no-wait [
button "test" [
print x
]
]
]
]
; Thanks!
@DavidConroy
function makes all set-words found in function's body local by default. To have x in global context use func instead:>> f: func [] [ return view/no-wait [ button "test" [ x: "hello" ] ] ]
== func [][return view/no-wait [button "test" [x: "hello"]]]
>> f
== make object! [
type: 'window
;...
>> x
== "hello"
@DavidConroy not sure if it's a bug or not but
/no-wait seems to be a culprit.f: function [] [return view [do [x: none] button "test" [x: "hello" probe x]] ] vs g: function [] [return view/no-wait [do [x: none] button "test" [x: "hello" probe x]] ] both has x as local (?? g) but only 2nd one doesn't work.
@nedzadarek
/no-wait is not the culprit. In the first case f calls view and waits until it finishes, and x has its context available because we're using it during f call. In the second case you explicitly ask to not enter View event loop, so you instantly get face object back, which has x in it bound to f. Problem is that f is gone, since function call was just finished. Hence the error message.
And I suspect that @DavidConroy uses stable build, because it was long ago patched to "context for x is not available", which is more accurate.
