Hello,
Does anyone know how to map a java.io.file to an IFile? I create a file and
I want to make that file into a type IFile. Thanks in advance.

Hey Raj,
I've found a workaround that may help you out. Assuming you have an IFile
object called "someFile", you can map to a java.io.File object as follows:
java.io.File file = new java.io.File (someFile.getFullPath( ).toString( ) );
Hope that helps,

I should make my question a little clearer.
I create a file, in some code, called sample.txt. I now want to give that
file an IFile handle, are there any suggestions on how to do it?
Thanks again

But remember, this only works for files that are in the workspace. If
the file is not in the workspace anywhere (i.e. some generic file
someplace else), you can't get an IFile to it.

Well, you could create a linked file in the workspace that works as a
surrogate for the non-workspace file.
(Also, when going the other way, from IFile to File, you want to use
getLocation() not getFullPath().)

Hi Bob and Rich,
Thanks for your help. The thing is that the file I'm creating is done on
the fly as my plugin runs and so it's not in the workspace.
Basically, this is what I'm trying to do.
I'm trying to create a newsgroup client plugin for eclipse and I create a
view in which the messages are displayed in. When I double-click a message,
I would like to open it in the text editor.
The way I'm going about this is that I'm grabbing the information from the
doubleclick event and writing it into temp file and I want to display this
temp file in the editor. From what I've read and what I've tried, it seems
that this is not possible if this file is not associated in the workspace,
as you guys have pointed out.
In your opinion, is what I'm trying to do possible?
Thanks again,
Raj

You don't really need an IFile if you don't intend to store anything on
disk - you could just create your own IEditorInput and IDocumentProvider
and provider your message in as an instance of Document.

Thanks Tom,
Do you know of any examples of how this is done? If so, could you point it
out to me?
Otherwise, I'll try to figure it out on my own. Thanks for your help

As long as the file is in the workspace, I think you can do it. Use the
..metadata area created for your plugin, which you can get the path of by
calling getStateLocation() in your plugin. toOSString() will get you a path
suitable for java.io.File and you're off and running. When you have a File
created there, call the following to get an IFile:
public IFile fileToIFile(File f) {
String p = f.getPath();
IPath path = new Path(p);
return ResourcesPlugin.getWorkspace().getRoot().getFile(path);
}
(I just typed that in; if it doesn't compile, fix it.) Then, I have this bit
of code lying around that will do the rest:
protected IEditorPart openEditor(IFile file, String editorId) {
IEditorPart editor = null;
IEditorInput input = new FileEditorInput(file);
IWorkbenchPage page =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage();
if (page != null) {
editor = page.findEditor(input);
if (editor != null) {
page.bringToTop(editor);
}
else {
try {
editor = page.openEditor(input, editorId);
} catch (PartInitException e) {
//log the error or something
}
}
}
return editor;
}
I haven't tried exactly this case and there's probably shorter code to do it
(I try to avoid Eclipse's IResource, uh, stuff as much as I can), but that's
the general idea.

Hi,
I just re-read your post and my problem lies in the fact that I'm creating
the file when I run my plugin, I have choice in where to store the file but
it's not registered in the workspace. Will this still work if the file is
not in the workspace. The other person suggested using IDocument and
IEditorInput and I'm not sure how to use this. Does anyone know how to use
the IEditorInput and IDocument as mentioned in a previous post? I'm looking
for examples to see how to use IDocument.
Thanks

You could use StorageDocumentProvider as the provider for your editor.
As input, implement your own instance of IStorageEditorInput and
IStorage (you could copy code from e.g. SystemFileStorage and
SystemFileEditorInput in PDE and modify it).
This way, you would be independent of whehter you write to a temporary
file or not. If do want to write a file, the other options given in the
thread might be a better option.

Hi,
So I used your idea Bob and I wrote up the following code:
File myFile = new File("F:/ePost/workspace/test.txt");
FileWriter fw = new FileWriter(myFile);
fw.write(sb.toString());
fw.close();
file = fileToIFile(myFile);
openEditor(file, IWorkbenchConstants.DEFAULT_EDITOR_ID);
I wrote the two other functions that were suggested:
public IFile fileToIFile(File f) {
String p = f.getAbsolutePath();
IPath path = new Path(p);
return ResourcesPlugin.getWorkspace().getRoot().getFile(path);
}
protected IEditorPart openEditor(IFile file, String editorId) {
IEditorPart editor = null;
IEditorInput input = new FileEditorInput(file);
IWorkbenchPage page =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage();
if (page != null) {
editor = page.findEditor(input);
if (editor != null) {
page.bringToTop(editor);
}
else {
try {
editor = page.openEditor(input, editorId);
} catch (PartInitException e) {
showMessage(e.getMessage());
}
}
}
return editor;
}
My output was that the file tried to open up in the editor and
in the texteditor, it said, "Resource /ePost/workspace/test.txt does not
exist."
Can someone tell me why this would happen and/or how this can be fixed?
Thanks again

Well, first of all, does the file exist? Second, is it actually in a
workspace?
My actual idea was to store the files in your plugin folder inside
..metadata, which I know are ok to read and write, not just at the root of
some workspace, which I don't know are ok.
Anyway, check this stuff, do a little debugging, and if it isn't obvious
we'll go from there.

Well,
The file does exist but it's not in the workspace. I think this problem
can be solved by adding the file to the workspace using the appropriate
commands and then maybe calling this code although, I have no idea of how to
add a file to the workpace by using java code. I've got a rough idea, but
if anyone has a clear idea of how to do it, your help would be greatly
appreciated.
Thanks

The rest of the paragraph tells how to use the path to make a file.

Originally posted by: bob.objfac.com
Maybe I've been cryptic. Every plugin is allocated a folder in the
..metadata/.plugins folder of each workspace. This folder is writeable and
AFAIK IFile-accessible. If your plugin's id is org.sample.myplug, that will
be the folder name. But you don't need to know that. getStateLocation() gets
it for you. You should be able to create a sub-folder there, write your temp
files into it and open those files in editors. More clear?
(I've gone a bit out on a limb because I don't know what sort of knucklehead
code there is in Eclipse that might assume/require that every file is in a
project - I believe Search makes this assumption - but I think that's the
simplest solution to what you want to do so I suggest you try it. If it
doesn't work, there are other options, which involve creating a new project
to put the files into. This is quite easy to do; a few lines of code. But
since the project would be user-visible, it's not such a good solution.
Hence, I have suggested this path.)

Hello,
I put in the following code as mentioned before to use the metadata
directory.
IPath filePath = ePostPlugin.getDefault().getStateLocation();
String fileNamePath = filePath.toOSString();
File myFile = new File(fileNamePath + "/" + "test.epo");
FileWriter fw = new FileWriter(myFile);
fw.write(sb.toString());
fw.close();
file = fileToIFile(myFile);
openEditor(file, IWorkbenchConstants.DEFAULT_EDITOR_ID);
I still get the same problem with resource not found error showing up in the
editor. Where should we go from here?
Thanks again,
Raj

Well, you remember when I said I'd never tried this? ;-} It looks like
workspaceroot's getFile() will return null if the file isn't in a project,
so I'm really surprised you got anything as civil as file not found. I would
have expected NullPointerException.
I'm not an expert on these crappy IPath/IFile things, but I can't see an
easy way to make what I suggested work without a project. If someone else
does, feel free to jump in.
There are two other ways to open something in an editor:
- Use IStorage, but these aren't editable unless you replace the storage
provider (editing won't work with .java files and I don't truly know what
kinds of files it will work with). See Ed Burnett's fileopen plugin for
working code: http://sourceforge.net/project/showfiles.php?group_id=73634
- Use linked files and a project to contain them, as is done by Matt
Conway's filedrag plugin. You can read the code by downloading the plugin
from http://sourceforge.net/projects/sunshade. This works just fine with
existing editors.
- Eclipse 3.0 is doing something (?) to make external files editable. Can
you wait? ;-}
That's it. I'm out of "helpful" advice. Good luck.
