Ok! Here is the long awaited inventory example! Call this file inventory.e [code] OPT MODULE CLASS item itemnum:INT pad1:INT description:ARRAY OF CHAR ENDCLASS DEF nextitem:INT,itemlist[32]:ARRAY OF PTR TO item PROC makeitem(describe:ARRAY OF CHAR) NEW OF item self.itemnum:=nextitem itemlist[nextitem]:=self ++nextitem IF nextitem>31 THEN Raise("ARG") self.description:=describe ENDPROC PROC getmask() OF item RETURNS mask:LONG IS 1 SHL self.itemnum PROC getdescription() OF item IS self.description CLASS inventory mask:LONG ENDCLASS PROC makeinventory() NEW OF inventory self.mask:=0 ENDPROC PROC additem(myitem:PTR TO item) OF inventory self.mask:=self.mask OR myitem.getmask() ENDPROC PROC removeitem(youritem:PTR TO item) OF inventory self.mask:=self.mask AND NOT youritem.getmask() ENDPROC PROC hasitem(myitem:PTR TO item) OF inventory RETURNS ret:BOOL ret:= (self.mask AND myitem.getmask()=myitem.getmask()) ENDPROC PROC hasany(items:PTR TO inventory) OF inventory RETURNS ret:BOOL ret:=(self.mask AND items.mask <> 0) ENDPROC PROC hasall(items:PTR TO inventory) OF inventory RETURNS ret:BOOL ret:=(self.mask AND items.mask = items.mask) ENDPROC PROC getitem(source:PTR TO inventory, theitem:PTR TO item) OF inventory RETURNS ret:BOOL ret:=FALSE IF source.hasitem(theitem) source.removeitem(theitem) self.additem(theitem) ret:=TRUE ENDIF ENDPROC PROC giveitem(destination:PTR TO inventory, theitem:PTR TO item) OF inventory RETURNS ret:BOOL ret:=destination.getitem(self,theitem) ENDPROC PROC useall(items:PTR TO inventory) OF inventory RETURNS ret:BOOL ret:=FALSE IF self.hasall(items) self.mask:=self.mask AND NOT items.mask ret:=TRUE ENDIF ENDPROC PROC list() OF inventory DEF count:INT,current:PTR TO item FOR count:=0 TO nextitem-1 current:=itemlist[count] IF self.hasitem(current) Print('\s\n',current.getdescription()) ENDIF ENDFOR ENDPROC [/code] And here's the code to test it out: [code] MODULE '*inventory' DEF lamp:PTR TO item, torch:PTR TO item, bag:PTR TO item, room:PTR TO inventory, mystuff:PTR TO inventory, lights:PTR TO inventory, allstuff:PTR TO inventory PROC getit(what:PTR TO item) IF mystuff.getitem(room,what) Print('You\'ve picked up \s.\n', what.getdescription()) ELSE Print('You aleady have \s.\n', what.getdescription()) ENDIF ENDPROC PROC main() DEF in[4]:STRING NEW lamp.makeitem('a lamp') NEW torch.makeitem('a torch') NEW bag.makeitem('a bag') NEW room.makeinventory() NEW mystuff.makeinventory() NEW lights.makeinventory() NEW allstuff.makeinventory() room.additem(lamp) room.additem(torch) room.additem(bag) lights.additem(lamp) lights.additem(torch) allstuff.additem(lamp) allstuff.additem(torch) allstuff.additem(bag) REPEAT IF mystuff.hasany(lights) Print('You are in a room with no doors and no windows.\n') Print('You see:\n') room.list() ELSE Print('It\'s dark.

Thinking back, I think that ChrisH already fixed PortablE for AROS so that the errors I ran into won't be there in the final release 6 version. He just hasn't come out with the final release yet. Recently I remember him cleaning up bugs on AROS and MorphOS both. I hope he finds time to finish up the release so I can continue the tutorial. @Magorium I don't know if the server services from VirtualBox would be more viable. There is an option to do something like that in the Icaros installer though, IIRC.

@SamuraiCrow: Ah ic. I took develop environment a little too literaly ;) Sorry 'bout that. Yeah, i am familiar with the problem you're facing. Missing VB-GA sux. I doubt that you didn't already think of this yourself (or perhaps you are unable to apply in practice) but whenever i need to transfer files from one box to another i use the VBox network. If i have to transfer out of the box'es i use an USB stick or serial port (installed virtual serial port on host-OS). This is the reason i was thinking about something like freenas in a extra Box in order to transfer back and forth between guest and host in a more consisent way Alas, it really doesn't make things smoother :( OT: Since you have more aros experience, do you think it would be viable to interact with the VM's server services from aros ? @cavemann: Thank you for sharing that link :). I didn't know about that. regards,

I had difficulty installing Icaros in such a way that I could transfer files to and from the host MacOSX 10.6.x environment. In the past I had used hosted AROS on Linux in VirtualBox so that I could use the VirtualBox Guest Additions. Editors have very little to do with what problems I'm having. I used TextEdit under MacOSX for the IRC tutorial series so it doesn't have to be anything advanced.

Would you mind to post the link to online material such as Books or Manuals we may need on E and PortablE? :)

Thank you for moving :-) Sorry I made a wrong assumption about the OS SamauraiCrow ... Ofcourse you are correct -> if you where using windows you could use the windows version :mestupid: So that would probably also mean that i wrongly assume portableE is written in E ? I intentionaly mentioned editors that are available for AROS, as i thought that _is_ the issue. Or did i misunderstand the intentional problem ? btw Annotate works for me under icaros desktop. PS sorry to see on that you mentioned having problems with compiling due to header errors. regards

I don't think the most recent version (2.7.8) has been ported to AROS yet. [url]http://hem.bredband.net/deniil/[/url]

I think it already is, isn't it? AROS ARCHIVES: [url]http://archives.aros-exec.org/index.php?function=showfile&file=utility/text/edit/annotate.i386-aros.zip[/url] From OnyxSoft: [url]http://www.onyxsoft.se/annotate.html[/url] It shows 2.7 on both..

Yes, Annotate does have AmigaE syntax highlighting. I've used it under OS 3. I hope that the latest version gets backported from OS 4 to OS 3 and AROS.

I thought Annotate had E language Syntax Highlighting and it is now available for AROS. I guess that could be a good editor under windows?

I use VirtualBox for Mac. I haven't used Windows for a good many years except at friends' and relatives' houses. If I had Windows, I could just use the Windows version of PortablE. I normally use hosted AROS from within a Linux virtual machine. But my Linux VM is getting hard to manage and I can't seem to get either Mac or Linux versions of X11 to enable the Backingstore option.

Hi SamuraiCrow, Sorry for (sort of) hijacking this thread, please replace or delete if wanted. [moved to new thread --SamuraiCrow] 1) could Frexxed ([url]http://daniel.haxx.se/frexxed/[/url]) be a viable option ? 2) if you are using VB then i assume u use windblows ? If so, perhaps programmer's notepad ([url]www.pnotepad.org/[/url]) is an option ? I realize then there is a problem with executing code that uses gui elements as E does not have support for them under windblows. It is an interresting topic, also for me, because it's a bit problematic: developing in other languages then c in combination with AROS -> the lack of a real configurable editor that is aimed for developers. I could not find anything else myself. atm i run two VB's one with windblows another with aros. This is because i have to test the software on two platforms and the editor is in windows. I use VB's internal network to communicate between the two, but i'm thinking of changing it in adding a third box with something like freenas. I believe aros does not has a remote-shell ? That would be a better option. Please share the experience (others are welcome) if you can spare the time. regards red: forgot to mention annotate ([url]http://www.onyxsoft.se/annotate.html[/url])

I apologize for not actually starting the example code, but I'm trying to get a decent development environment going for AROS and PortablE. I'll probably just install Icaros on a VirtualBox VM and forget about being able to transfer files in and out except via the internet.

Ok class, welcome to the PortablE programming course. For these lessons, we're going to be implementing a bitset class. This will allow the presence or absence of up to 32 items to be mapped into only 4 bytes of memory using logic operations. In order to make a class to hold items, the first thing we have to do is make a definition of what kind of items we can put into storage in the bitset. What we need for this to take place is to make a unique identification number for each item starting at zero. The next thing we want is a name so we can identify each item going into the list. Thirdly we'll need a way to list the contents of the set. If there are are any questions, I'll answer them as we go. We'll be making this using a purely object-oriented approach. Anyone who has been in the IRC channel discussions will have to note that these lessons are in PortablE rather than AmigaE so they will look a little different.

Thanks.

Alright! Feel free to create a new thread anytime you like. I have made you the forum Moderator for PortablE. You can upload attachments if you need to. Let me know what else you need. You can make them stickies as well.

I'd prefer to do it as forum threads. :)

You know that is a very good idea. I'd love to host some E and PortablE tutorials here on AROSWORLD. We can do it in two forms: 1) As an article page 2) As forum threads. Let me know which was you prefer?

Well, I am holding E classes on Sunday afternoons at 3 PM CDT (8 GMT) on the #AmigaE channel on irc.Freenode.net but it's turning more into a discussion on how to implement a game engine in E. We still have the code from the first two months of classes but not the logfiles. I had mainly offered to teach Cammy about E but she invited others to learn as well. You're welcome to show up also but since some people couldn't make it every week, it's mainly there for me and Cammy. If you'd like, I could start over here in a thread about learning PortablE.
