File I/O Tool
 

This is a neat file I/O tool I made for [URL="http://www.alice.org/community/member.php?u=18410"]TauTrumpsPi[/URL].
Import the object into the world you want to use it in.
Don't rename it and don't delete any of its variables, methods or events.

Set IOTool's variable named current_file to the file to be used. Change it when necessary.
Use any of its methods wherever required.
Some methods have basic help/info in comments inside them.
Any method that returns a value (eg read_all or get_lines) will write its value to IOTool's variable named returnString (or returnNumber for get_lines).

Update 1.1 - should work perfectly now.
Update 1.2 - now it actually definitely works; trialled and tested.

Cool! It looks interesting!

I can't get it to work... It seems like you're missing an integer variable of some sort

Here's the error

[code]
Error during simulation.

Throwable that caused the error:

My head is spinning, partly because Arty just made a new manly batch of awesome, but also partly because I don't know what to do with it.

Can you write new .txt files with it?

[QUOTE=TauTrumpsPi;37467]I can't get it to work... It seems like you're missing an integer variable of some sort

Here's the error
[/QUOTE]Give it a second to start before you use it, don't use it on world start.
If that doesn't work, do you have an [I]"on world start" [/I]event under the IOTool heading? If you don't then there should be one.

[QUOTE=DensetsuNoKaboom;37494]Can you write new .txt files with it?[/QUOTE]Yes, and read them. (they don't have to end in .txt, but they should be plain text files ie. not images etc.)

I got it! Thank you!

Thanks! This will be very useful!

EDIT: It's not working. It creates new files all right but when I try to make it write a string variable to line 1 of the created file, it gives me an error.

Mr. Kidnapper does not understand the uses of this. Is it supposed to assist in creating save/load states?

That is the reason I originally asked for it, yes.

Having the same error as densestu.:(
btw, you should add a method that converts strings into numbers:)

[QUOTE=room14;37562]Having the same error as densestu.:(

Yeah, so you can make it read a "number" that is in the file and change it to a number and set a variable to that number, so it wouldn't be just strings you can save!

I haven't come up with anything to use it for yet, but it is sounds very cool!

I updated it to a working version.
I'm considering the other suggested features.

Future feature division?

EDIT: I think you should also know that this error occurs when I start playing a world with the object in it.

If you want uses, then you could use it to save PoV locations, booleans, and other number variables constantly every second to, for example, make a game a bit like Harvest Moon or other example sim game. In fact, I would applaud you for making a persistent world sim game. Persistent World could be achieved by making the world relative to computer date time, if you didn't know how.

You know, I find it funny that I ask you to do this and then a week later I learn how to do it in C++. Odd coincedence.

I worked out what was wrong, its fixed.
Its updated and definitely works now, I tested it on a non-modified Alice.

Bbbbububbuubuubbubut...

At least this time, it didn't happen until I tried to write a variable to line 1.
EDIT: And hey, it works when I overwrite the entire file with text rather than one line! And it works when I load that file!
EDIT2: And this is my 600th post!

No, that's just you using it wrong.

You cant write to line 1, because line 1 doesn't exist.
It is like a list, it starts at line 0.
If you want a new line at any time just add in [I]\n[/I] .
Once the line exists you can write to it.

[QUOTE=arty-fishL;37631]
If you want a new line at any time just add in [I]\n[/I] .
[/QUOTE]

Add it in where?

Wherever you're writing just add [I]\n[/I] into the string for a new line. For example:

"hi there \n my name is Bob\nGreat!"

would produce

[CODE]hi there
my name is Bob
Great![/CODE]

Anyway, what you were looking for was writing to line 0, not line 1.

I could maybe update it to change writing line 0 to line 1 instead (so the numbers are shifted down one) and so on. I could also add a function to create a new line or set of lines; one for changing a string to a number; maybe even also a variable saving function.

It failed as well when I tried writing to line 0.

[QUOTE=DensetsuNoKaboom;37684]It failed as well when I tried writing to line 0.[/QUOTE]Ensure the file exists first - use new_file with overwrite set to false. If writing to line 0 doesn't work then try using write. It should work, I've tested it lots.

Is this compatible with Mac OS X? I recognized it started with C:// so I changed it to the Mac filepath and when I ran the world it threw an error:

You could try updating Alice, there's a newer version of 2.2 available, but I'm not sure that will help.

I already have the latest version. I think it has something to do with the file system being different on Mac OS X. I think this is a very important feature that needs to be implemented into Alice and I am sad that it isn't working :(

Is there a way I can change how Alice accesses the internal files? It can't find one of its own files, which is really annoying

[QUOTE=Dj Tech42;38238]Is there a way I can change how Alice accesses the internal files? It can't find one of its own files, which is really annoying[/QUOTE]Elaborate on this error, I may be able to help. What file cant it find?

/Applications/Alice 2.2.app/Contents/Required/jython-2.1/Lib/javaos.py

javaos.py is the file it is looking for, and I know where it is ^. Is there some way I can show Alice where to look for the file?

And the Mac version was released September 2010.

It's still coming up with the error no matter what I do

[QUOTE=Dj Tech42;38552]It's still coming up with the error no matter what I do[/QUOTE]Sorry about taking ages to respond. Try this world. Play it in Alice, wait for it to finish, then try restarting Alice.

It says patch failed :(

[QUOTE=Dj Tech42;38746]It says patch failed :([/QUOTE]
OK, try the new one, even if it doesn't work, it will print out debug info so I can see what is wrong

Ok here's what it said:


START PATCH
Resource Transfer patch failed
Debug: File not found - resources\common\ResourceTransfer.py (No such file or directory)
Patch failed
END PATCH

The said file does exist, but it is under required/resources/common/

[QUOTE=Dj Tech42;38857]The said file does exist, but it is under required/resources/common/[/QUOTE]Sorry I am late again, I've been busy elsewhere - and in thinking about this. I'm at a loss, if it can't even be patched then I don't know what to do.

You haven't by chance stuck Alice in the system programs directory instead of your local home directory have you? Because if you have, then I would try moving it to a folder on your local home directory instead, the error may lay with permissions or similar.

It's ok, you don't need to worry about it anymore. I can't even run Alice 2.2 on my computer now due to the code in Alice being too old.

Well, Alice 2.2 is running on my computer again, but still no luck with the plugin. :( I will probably have to try it on a different computer.

I think I might have fixed it! I enabled scripting on Alice and fixed the javaos.py path reference! I just need to try the actual methods now.

It worked! Thanks so much arty for creating such an awesome tool!
