Creating a library using EiffelStudio
by David Jenkins-5

Rate this Message:
How do you create a library using EiffelStudio 6.2 GPL? The 'New
Project' dialog offers the option of creating one of four types of applications (basic, .NET, WEL or Vision2), but not a library. I've searched the on-line documentation but can't find any mention of creating a library. ------------------------------------ Yahoo!

You're agreeing with something I didn't say, Peter ;-) Yes, maybe David was asking how to make a precompiled library, but I suspect he was asking about a plain, simple, class library: similar to the ones in $ISE_EIFFEL/library: base.ecf, net.ecf, vision2.ecf, etc. - Peter Gummer ------------------------------------ Yahoo!

Hi Peter,
Yes, I did mean creating an Eiffel library, like the base, time, store, etc. libraries. Sorry for not making that clear. I tried editing (hacking) an existing .ecf file, but wondered if there weren't a way to create an Eiffel library using the IDE, as you would for application projects. The IDE accepts my edited .ecf file, but for some reason gives an odd result with one of the libraries (time) that I need my library to reference. The 'time' library appears in the cluster view, but when I expand it (click on the '+'), it displays itself and the other libraries again, not the classes in 'time'. Also, my library fails to compile, because classes in 'time' are not visible that need to be. This is a long way of explaining why I wanted to know if it's possible to create a library with the IDE, expecting that it would do a better job than I have. (I'm feeling nostalgic for ACE files, which IMHO were easier to understand and more concise than the XML-implemented .ecf, and could probably have just as easily, or with just as much difficulty, been automated by the IDE.) > > Peter Horan wrote: > >> > >> I suspect David was asking about a class library (i.e., a read- only > >> collection of clusters with their own .ecf file) rather than a DLL. > > > > First, I agree that precompilation should be an option at project > > creation. > > You're agreeing with something I didn't say, Peter ;-) > > Yes, maybe David was asking how to make a precompiled library, but I suspect > he was asking about a plain, simple, class library: similar to the ones in > $ISE_EIFFEL/library: base.ecf, net.ecf, vision2.ecf, etc. > > - Peter Gummer > ------------------------------------ Yahoo!

Me too, David. I was looking at an old ace file the other day, for the first time in many, many months, and I was struck by how clean and legible it was. Peering into an ecf file is hard work. Some of us complained about this when ecf was sprung on us by surprise a couple of years ago, but we were told not to worry, we would never look at the XML because the Project Settings dialog would do everything. Well the Project Settings dialog is good, but I usually edit the XML directly because it's quicker for most mundane tasks. Your current problem is sadly ironic in this respect. Someone was looking for JSON support in Eiffel a few days ago. Wouldn't it be nice if ecf files were JSON rather XML! David, why don't you paste your ecf XML into an email? Maybe it will be obvious why the time library part of it isn't working when we see the XML. - Peter Gummer ------------------------------------ Yahoo!

Hello Manu,
Thank you for the reply. I added the 'time' library to my project just as you explain, but still got the odd behavior from the IDE that I described. If you like I could send you the .ecf file that I've created, by hand- editing to get something to work with, and then revised solely by the IDE. <manus@...> wrote: > > > (time) that I need my library to reference.

Does support the notions of variable state and flow control? If not, then it won't be adequate for specifying an Eiffel configuration, since you need to be able to express things like if target_platform.is_windows then library_specs.append (WEL) end Ace notation was on the right track, but it was trying to impose an Eiffel syntax onto the traditional declarative style of makefiles. Better, I think, would be to use Eiffel itself, though I would like it to be easier to use the language declaratively for problems like this. Greg C ------------------------------------ Yahoo!

Manu,
I've found the cause of the odd behavior I described. I copied the .ecf file for the 'time' library, then edited it to start on my library. I didn't change the 'uuid' attribute in the 'system' tag. Then I added a reference to the 'time' library to my library. Apparently the uuid actually means something to the IDE. I changed it to another value, now EiffelStudio recognizes 'time' in my library and behaves correctly. Next time I'll just create a cluster and reuse it if I need to. I'll leave library creation to the experts! <manus@...> wrote: > > > If you like I could send you the .ecf file that I've created, > > by hand- editing to get something to work with, and then > > revised solely by the IDE. > > It would certainly help. > > Manu > ------------------------------------ Yahoo!

The UUID is used to uniquely identify a library. Usually it is best to discard the UUID part as it is automatically created by EiffelStudio when you first edit the configuration file.

Here's what the above currently looks like in XML: | <library name="wel" location="$ISE_LIBRARY\library\wel\wel.ecf"> | <condition> | <platform value="windows"/> | </condition> | </library> Now I'm no JSON expert, but after spending all of 30 seconds looking at http://www.json.org/example.html I imagine it would become something like this: | "LibraryList": { | "wel": { | "location": "$ISE_LIBRARY\library\wel\wel.ecf", | "condition": { | "platform": "windows" | } | } | } > Better, I think, would be to use Eiffel itself, though I would like it > to be easier to use the language declaratively for problems like this.
