Basically the url to your resource, that means if you
upload the
style-sheet to your root folder as a resource and give it the title
'Style Sheet', it is accessible with:
@import "http://localhost:8080/StyleSheet";
For a production server you have to replace the host-name with your
real domain-name, else people from outside won't see your design.
We should start a FAQ on SmallWiki :)
Lukas I saved the image and reopen it and it
seems to me that the
import I specified was lost. Is it possible or my mistake?
This should not happen, as the template and the style-sheet are saved
as a property within the structure where you defined it.
One thing that could cause that problem is if you use this line to
start your server again:
server := SmallWiki.SwazooServer startOn: 8080.
As I write in the comment is only intended to be executed the first
time and should be removed afterwards, because it initializes a
completely new wiki. Just use
server start.
to restart the wiki again, after you opened an image. Of course,
shutting-down and starting-up the server could be made automatically,
but it is not easy in VW as it is in Squeak, I think.
I do not know but I can think that this is more robust in VW but we
should simply ask.
You are basically suggesting the naming-conventions of
the design
patterns book. When I implemented those visitors I didn't had that
book yet, so I copied the conventions of the refactoring-browser. I
don't know what is better and what the idea of John Brant was when
writing his visitors.
Of course it is easy to change the message-names, but I don't know if
that really helps much. I can life with both conventions, in 'ROE' the
design-pattern and in 'Formulator' a modified refactoring-browser
approach is taken.
Sure I can live with that too, but imagine all the newbie that will
follow my lecture and the lecture of roel, so this is only a cosmetic
change but it is really worth because it helps the people to know where
they are. I realized that because I was coding at least 5 visitors for
the bibtex stuff of roel and I was confused not to find the same.
- I saw that
the parent of a resource is not the page having a
reference to it but the folder in which the resource is located. I
can understand why: multiple pages in the same folder can refer to
the same resource. Now is there a simple way to know from which page
a resource is accessed?
Pages do not have children and they might even reference resources
from different folders than their parent.
If you want to know all the structures referencing a specific other
structure (this doesn't have to be a resource necessarily) just use
something similar to the code below. One could even add a message to
Structure itself to get all the references more easily:
Structure>>references
"Return all the structures referencing the receiver."
^(VisitorReferences collect: self root to: self)
collection
We should add that.
> - how can I find the name and not the title of an uploaded image?
The name? You might call #id to get the id of the image or call #url
to get the full path of it. But the filename where it is was uploaded
from is not stored anywhere, I think this is not really needed and
platform-dependant anyway.
It is important because imagine I want to upload a collection of
picture and then after some reason
I want to transform them (thumbnail or what ever) and I want to save
them. I do not want to have image1, or just the title. Here we are
losing an important semantical information. Note that I did not talked
about the path but the file name like stairInteractif.tif vs stair.tif
(those are just images of my books and their names are really
important).
Cheers (& see you tomorrow in the Java lecture :P),
I cannot attend it, but I will follow all the other ones.
