Red/View and other Red GUIs

Request-file is the function you want.

Use ? request-file to see details, and play in the console with it, to see how the refinements work. You can also do ? request to see the other requestors that are available.

@greggirwin Thank you!

Here is an interesting example of Red's code = data property: with five LOC I add a new item to the console's menu

; get console face
cons: first head system/view/screens/1/pane

; add to console menu
append last cons/menu ["Check for updates" check-update]

; modify the body of the on-menu actor function
body: body-of :cons/actors/on-menu
insert third body [check-update [do %check-update.red]]

; rebuild the function from the spec and the modified body
cons/actors/on-menu: func spec-of :cons/actors/on-menu body

@toomasv

@meijeru Beautiful! :+1:

@pekr

Really cool!

Gregg Irwin

@greggirwin

Very cool indeed.

Can you post the code for %check-updates.red as well?

Gregg Irwin

@greggirwin

Ah, I see your gist in the other room now. Thanks!

@planetsizecpu

@meijeru Wow, useful!

Something I'm currently working on: Hamiltonian cycles generator

Galen Ivanov

@GalenIvanov

I need to improve the code, because the program crashes when I try bigger sizes. I don't know if this due to memory leak or recursion.

Boleslav Březovský

@rebolek

@GalenIvanov try recycle/off, it may be some GC bug.

Galen Ivanov

@GalenIvanov

@rebolek Thanks, I'll try it.

Gregg Irwin

@greggirwin

@GalenIvanov cool. Thanks for posting.

Galen Ivanov

@GalenIvanov

@greggirwin Thank you! It's just a WIP, I'll post the source of the finished projects on Github - I have ideas for 2 games based on this.

Galen Ivanov

@GalenIvanov

@rebolek A quick update: I decided to see if the program crashes when compiled. Surprisingly it doesn't crash. In the console it starts crashing with inputs around 16x16; the compiled one successfully generated a hamiltonian cycle on a grid of 40x40 points.

Boleslav Březovský

@rebolek

@GalenIvanov interesting, I'll check how my crashing stuff behaves when compiled because there's certainly some GC error in the interpreter.

Galen Ivanov

@GalenIvanov

@rebolek OK, thanks! I'll post my source when I'm ready - I don't rule out the possibility of more mistakes from my side.
By the way, success with 70x70 (it took maybe 15 minutes, but proves that my concept works) - I'll need much smaller grids, but was annoyed by the crashes.

Boleslav Březovský

@rebolek

@GalenIvanov crash is definitely not your problem. You should get an error, if your code is wrong, but not a crash.

Galen Ivanov

@GalenIvanov

@rebolek Yes, exactly!

Boleslav Březovský

@rebolek

definitely NOT...sorry for the typo :)

@endo64

@GalenIvanov "In the console it starts crashing with inputs around 16x16" is it on GUI console or both GUI and CLI?

@qtxie :point_up: I can't recall if garbage collection for image!s was implemented?

@qtxie

@9214 Not yet.

@9214

I generated FASS curves and L-system trees of quite a monstrous size back in the day, and haven't seen any crashes, only errors due to pair! overflow, which were expected.

Galen Ivanov

@GalenIvanov

@endo64 I only tested it on the GUI console

Vladimir Vasilyev

@9214

GUI / CLI difference has no bearing here, it's interpreter issue. @GalenIvanov you ought to provide at least some error or debug message, if you want it to be resolved. "It crashes" isn't terribly useful.

Galen Ivanov

@GalenIvanov

@9214 I'm aware that it could be entirely my fault. I just realized the big difference between the code inerpreted in the GUI console and the compiled code. Unfortunately I didn't receive any error message. I tried to naively debug the code with printing/probing some values, but when the program crashed in the console, I never got any error message. I'll post a link to my code tomorrow. Thank you all for your feedback.

@9214 BTW, here is my take on L-systems. I also didn't get any crashes.

Vladimir Vasilyev

@9214

@GalenIvanov it 's our fault that Red crashes, not yours :wink: Try to compile console in debug mode (-d flag) and launch it from command line, then paste here stack trace that you'll see after crash.

Galen Ivanov

@GalenIvanov

@9214 Thank you for your support. In the meantime I updated Red to the automated build - red-25sep19-f753e25c.exe - and there is no problem anymore, not a single crash. Sorry for wasting your time and not trying the most obvious thing. The version I have been using until now was really old - built on 22 Nov 2018.

Does anyone remember why drop-list doesn't have a readable text facet? i.e., it's not set on selection.

Galen Ivanov

@GalenIvanov

I almost finished the game for which I was coding my generator of Hamiltonian paths. I present you the "Island Alleys"

It is a logic puzzle in the vein of Slitherlink.

You need to connect the dots by clicking (not dragging) between them and form a closed loop that goes through all the dots on the grid. The numbers are placed only where two or more "alleys" meet at a right angle and indicate the total distance to the shore in all directions.

Galen Ivanov

@GalenIvanov

I'll add a thorough step by step example solve later.

Enjoy!

Island Alleys

Semseddin Moldibi

@endo64

@GalenIvanov Very nice! You could also add a textbox so the user can select a specific game (value for random/seed).

Galen Ivanov

@GalenIvanov

@endo64 Thank you! Yes, that would be a good feature and it's easy to implement. I also need to make the "About" window modal; some of the contents of the canvas/draw block don't need to be computed at each click but only when needed.

One thing I observed (I'm not 100% sure though, I'll check tonight at home) is that style doesn't work correctly for the size of the button - the y part of the pair is not taken into consideration in Win 8.1. Here, on my Win 10 at work it's working correctly.

Toomas Vooglaid

@toomasv

@GalenIvanov Very nice game! :+1:

Toomas Vooglaid

@toomasv

@GalenIvanov When you add grid size to the title, I think you should copy the text first, otherwise several grid sizes are added if player reloads new game in desperation (as I did).

Toomas Vooglaid

@toomasv

Galen Ivanov

@GalenIvanov

@toomasv Thank you and congratulations for solving it! Apparently you don't neeed an elaborated step-by-step-how-to-solve-it :) Thank you also for finding the bug in the title - I fixed it and moved the title creation in the init-boardfunc, where it belongs.
I have several more ideas for games on such a grid, I hope I'll finish them too.
