60 lines Binary Puzzle in php and ncurses
« on: July 29, 2013, 12:42:20 am »
I decided to try implementing a binary puzzle as well, but in php and ncurses and, to my amazement, I managed to do it under 75 lines of code. Paste this in a php file, uncomment the ncurses and gmp extentions in php.ini and run this in command line. Supports color, multiple grid sizes, multiple puzzles and all the conditions to win! Also optionally takes a puzzle set filename and puzzle number as argument.

puzzle.php:

How'd you get the funky syntax coloring?
Due to dissatisfaction, I will be inactive on Omnimaga until further notice. (?? THP hasn't been much success and there's also the CE. I might possibly be here for a while.)
If you want to implore me to come back, or otherwise contact me, I can be found on GitHub (bluebear94), Twitter (@melranosF_), Reddit (/u/Fluffy8x), or e-mail (if you know my address). As a last resort, send me a PM on Cemetech (bluebear94) or join Touhou Prono (don't be fooled by the name). I've also enabled notifications for PMs on Omnimaga, but I don't advise using that since I might be banned.

Blame the code tag plugin I guess?

In Firefox I can't see the content of your code tags. It just says "Array". Though it works fine in Konqueror. Weird. ???

Now it should work. And yeah everyone is doing those lol. But in my case I wanted to see how optimized I could do this.

Yeah, I kept it to the strict minimum, so drawing all the stuff takes like 2 lines. I have a level select though.

Lol I have 2900 lines of C#, 500 lines of C++ and 60 lines of assembly, and that's not counting anything that has to do with user interaction (there's not a lot of code there, maybe 200 lines).
About 1300 lines have to do with tutorial mode, but those are also used in puzzle generation (to make sure that lower-level puzzles don't require hard steps, as well as to ensure that higher-level puzzles do require hard steps).
Most of the rest is puzzle generation.

Lol nice one juju. :P I really meant making the code 60 times smaller, though. But of course I was kidding, since I'm not even sure if that's possible. :P
In case you are wondering where I went, I left Omni back in 2015 to form CodeWalrus due to various reasons explained back then, but I stopped calc dev in 2016 and am now mostly active on the CW Discord server at https://discord.gg/cuZcfcF

I think a better comparison would be how many bytes does it use up because it could be written in one gigantic line.
I currently don't do much, but I am a developer for a game you should totally try out called AssaultCube Reloaded download here https://assaultcuber.codeplex.com/
