When clicking on a location type in the output window of eclipse, you can go to that file (location).
I would like to be able to trigger this with a method in rascal.
So to be clear, I have the location of a java method, I would like to trigger eclipse to focus on this file through rascal.
Take a look at the util::Editors module. It contains an edit function that opens any file you pass it, with the relevant editor, with optional highlights.
Note, that if you have a logical location like java+method://... you will have to lookup the actual physical location of the method in the m3 model using IO:resolveLocation, and use that. For example:
rascal>import IO;
ok
rascal>resolveLocation(|java+method:///io/usethesource/impulse/language/LanguageRegistry/IMPFileEditorMapping/setTheDefaultEditor(org.eclipse.ui.IEditorDescriptor)|)
loc: |project://impulse/src/io/usethesource/impulse/language/LanguageRegistry.java|(15638,134,<433,8>,<436,9>)
rascal>openEditor(resolveLocation(|java+method:///io/usethesource/impulse/language/LanguageRegistry/IMPFileEditorMapping/setTheDefaultEditor(org.eclipse.ui.IEditorDescriptor)|))
You are looking for openEditor in util::ValueUI.
First import util::ValueUI;, then try
openEditor(|project://rascal/src/org/rascalmpl/library/Map.rsc|);
and an editor for the Map module will open.

Hello,
I'm an eclipse plugin development newbie looking for pointers to get me started on a particular project.
I am trying to build an eclipse plugin that will automatically construct a working set from a text file that simply consists of a list of file path names. The files/items need not share any parent directories. The rough idea is represented in the following diagram:
I am not asking for the solution to this task. That's the over-arching goal. To achieve that goal, I want to conquer some smaller goals first.
With that in mind, here's the smaller goal I'm currently trying to tackle:
In Eclipse, how can I prompt the user for a single file's path, and then add that file to an existing working set?
I'm not sure where to start. Should I work directly off of the existing org.eclipse.ui.workingSets extension point? Or should I use a collection of other extension points? How do I convert strings into something that can be added to a working set? Do I write code that directly modifies the workingsets.xml file?
Even with a much simpler goal, I still feel quite overwhelmed with the vastness of eclipse extension options. There are probably many ways to go about implementing something like this, but I just need one to get started.
Thanks a bunch!
To manipulate working sets you use the working set manager interface IWorkingSetManager. Get this with:
IWorkingSetManager manager = PlatformUI.getWorkbench().getWorkingSetManager();
From this you can get a particular working by name with:
IWorkingSet workingSet = manager.getWorkingSet("name");
The contents of a working set is an array of IAdaptable objects:
IAdaptable [] contents = workingSet.getElements();
You add to the contents by adding to this array and setting the contents:
IAdaptable [] newContents
.... get new array with old contents + new contents
workingSet.setElements(newContents);
A lot of Eclipse objects implement IAdaptable, for a file in the workspace you would use IFile. You can use dialogs such as ResourceSelectionDialog to select resources from the workspace.
I am using MS UIAutomation in C++ to control a third party WPF application. I can read the value of an edit control (IUIAutomationElement objects). When I try to set the value with SetValue (IUIAutomationValuePattern objects) it does not return an error, but does not set the value of the edit control.
The manifest contains , the application is signed and is run from C:\Program Files.
I experienced that some UI Elements do not implement the UI Automation Provider correctly, as a result some patterns do simply not work as expected or even fail (although they are shown available).
To verify that the object is corrupt and not your code you could use the ValuePattern via Inspect.exe. Open Inspect -> select the control -> Action (Toolbar) -> ValuePattern.setValue
As a workaround I would suggest you to use SendKeys. If you need to focus the element first, yourAutomationElement.setFocus() is your friend. If setFocus does not work get the ClickablePoint/BoundingRectangle of the AutomationElement and use user32.dll in order to click the object.
I wanted to run a bat file in which it can import preferences from a location (which was exported manually). I searched for the command which would import preferences but, could not find any.
There is no existing code to do this. You would have to write an Eclipse headless application that does something like this:
IPreferencesService service = Platform.getPreferencesService();
IExportedPreferences prefs = service.readPreferences(file input stream);
// TODO create IPreferenceFilter array to filter what you want
service.applyPreferences(prefs, filter array);
See the source of the import preferences page org.eclipse.ui.internal.wizards.preferences.WizardPreferencesImportPage1 for an example.
Backstory: I was looking for something similar and, a few tabs back, I've stumbled on a "half-an-answer"/alternative solution. Even if the thread is old might still turn in handy ...
In this page the author talks about using -pluginCustomization parameter inside the eclipse.ini file
-pluginCustomization
plugin_customization.ini
-startup
plugins/org.eclipse....
The plugin_customization.ini file is similar to the *.epf file, same variables minus the /instance/ prefix (maybe because this way they are interpreted/applied at product(eclipse) level and not as per-workspace preferences).
I'm setting up a series of preferences in my Eclipse (3.5.2) application and I'm having a problem with the FileFieldEditor. I want to allow the user to specify a log file to print output to. Often, this will be a new file. But when I use the file select dialog with FileFieldEditor, it complains that the file doesn't exists ("Value must be an existing file"). Is there a way, without extending the FileFieldEditor class, to suppress this error and have Java create that file if it doesn't exist? Thanks!
When I look the source code of org.eclipse.jface.preference.FileFieldEditor, the only solution would be to extend it and write your own version of a FileFieldEditor, with:
an overwritten changePressed() method in order to keep the file path even if the file does not exists
an overwritten checkState() method in order to avoid that error message.
So I do not see a way to avoid that FileFieldEditor extension here.
I've built an eclipse-based product, and I want to set the default workspace used by the Product. Currently, when the "Workspace Launcher" pops up for the first time, the default workspace location is just in the same directory as the Eclipse Product executable. I'd like to change to something like USER_HOME/myworkspace.
I can't seem to find a setting for this, but I'm guessing / hoping its a setting in my product_configuration.ini.
Cheers!
here is a more easy way
Once you have Eclipse up and running you can open Window-->Preferences-->Editors-->Startup and Shutdown. Click the first box that says Prompt for workspace on startup.
Or In your config.ini file ull've this line (or look in configuration.settings\org.eclipse.ui.ide.prefs)
//The default workspace location
Osgi.instance.area.default=#user.home/workspace
try changing this
Here is what needs to be done.
Wherever eclipse is installed go to the "configuration" directory and open the config.ini file in there.
Windows paths normally look like this:
C:\Users\Wilbert\Documents\Installers\Eclipse\eclipse
You will probably find something like this in the config.ini file:
osgi.instance.area.default=#user.home/workingspace
You need to change that to[Getting rid of the "#" and using forward slashes instead of back slash]:
osgi.instance.area.default=C:/Users/Wilbert/Documents/Programs/CS111B(Java)/Practice Programs/Projects
I just did it and it worked.
In your product (.product), go to the "Configuration" tab. Under the "Properties" section, add the property 'osgi.instance.area.default' with a value of '#user.home/myworkspace'. When you export your product, this property will be automatically added to your product's configuration file (just as ayush and Wilbert Sequeira were manually doing).
Note that only an exported product will use that configuration. When running your product in the Eclipse IDE, the workspace location will be overridden by your IDE's configurations.
The now-defunct Symbian WRT product did this. Looking through the sources, it seems to be done by a p2.inf file in the product package. See the screenshot below:
The first yellow arrow is for Windows and the second for Mac and Linux
In your .product file you can specify this as part of the programArgs element.
<programArgs>-data #user.home/MyWorkspace</programArgs>
Note that you can customize config.ini for individual platforms in the product descriptor (*.product) editor. But it never worked for me - hence that hack using P2. It may be working now as I was working with either 3.5 or early 3.6 when I last tried it.
Have a look at the following tutorial: http://hexapixel.com/2009/01/12/rcp-workspaces.
You said in your comment to the question "I just want to prepopulate the selector window with a certain default location".
You can do just that in PickWorkspaceDialog's (from the tutorial) getWorkspacePathSuggestion() method:
private String getWorkspacePathSuggestion() {
StringBuffer buf = new StringBuffer();
String uHome = System.getProperty("user.home");
if (uHome == null) {
uHome = "c:" + File.separator + "temp";
}
buf.append(uHome);
buf.append(File.separator);
buf.append("My App Name");
buf.append("_Workspace");
return buf.toString();
}
For this to work, you do have to create your own dialog though, and I can't tell if that's an option from your question...
In your .product file within the block add:
<property name="osgi.instance.area.default" value="#user.home/workspace" />
And when you build your product, the default config.ini will have this property set.
Details are in the Eclipse docs regarding the various variables.
To set the workspace location programmatically, use:
Platform.getInstanceLocation().set(new URL(...));
