I want to change some default user settings in Eclipse using custom plugin. There are constants that define these settings (Constant Field Values) What should I do to set some of them in Plugin? For example, I want to switch on line numbers or save resources before launch (there are constants for such things) by default. How can I do that? Tried something like this, but nothing changed:
String lineNumbers = AbstractDecoratedTextEditorPreferenceConstants.EDITOR_LINE_NUMBER_RULER;
EditorsUI.getPreferenceStore().setValue(lineNumbers, true);
This question is not about finding constants tied to some settings, it's about finding an approach to change them.
I execute code in one of my Plugin classes. It looks like that:
String lineNumbers = AbstractDecoratedTextEditorPreferenceConstants.EDITOR_LINE_NUMBER_RULER;
void initVal (String lineNumbers){
EditorsUI.getPreferenceStore().setValue(lineNumbers, true);
}
Also tried this one:
IPerspectiveRegistry perspectives = PlatformUI.getWorkbench ().getPerspectiveRegistry();
void initValues (IPerspectiveRegistry perspectives){
perspectives.setDefaultPerspective ("org.eclipse.ui.resourcePerspective");
}

Can someone please help me with this, am trying to use OpenFileDialog class from System.Windows.Forms to open a file dialog and read the selected file. Then, this error showed up. I've referenced it but still the same, below is the code.
`using UnityEngine
using UnityEngine.UI
using System.Windows.Forms;
public class OpenFileButtonScript : MonoBehaviour
{
public TextFieldScript textFieldScript;
public void OpenFile()
{
OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialog.Filter = "Text Files (*.txt)|*.txt|All Files (*.*)|*.*";
openFileDialog.FilterIndex = 1;
openFileDialog.Multiselect = false;
if (openFileDialog.ShowDialog() == DialogResult.OK)
{
string filePath = openFileDialog.FileName;
string text = System.IO.File.ReadAllText(filePath);
textFieldScript.inputField.text = text;
}
}
}`
It may look like you have access to all of the native Window system libraries, but it just looks like it. In actuality, a lot of the time you're simply given stubs, or shims, that look like the full Window libraries, because there's a certain element that Unity wants to use from those namespaces. If you think about it, the code you present above, what do you think it should do on Android or Nintendo devices? The simple answer is, it simply won't work.
Generally in cases like this, you have to gain access to the native operating system, and perform those calls directly. For example, there is a file browser asset on the Asset Store, that does this for you. It's not free, because the process isn't trivial.
Depending on how much effort you want to put in, you CAN read files from the local file stores (to varying degrees based on platform). It's possible to read the list of files in a location, and use either uGUI or UIToolkit to create your own File Open Dialogue box. Again, this isn't a trivial task either. So you have to be sure that you'd want to go down that path.
I'm currently writing an Eclipse plugin. In it, I want to programmatically open an editor and select a portion of the text. The opened file does not have to be imported into the workspace (that's why I'm using IFileStore in the code below).
I'm using code similar to this:
IFileStore fileStore = EFS.getLocalFileSystem().getStore(localPath);
IEditorPart part = IDE.openEditorOnFileStore(page, fileStore);
final int posStart = ...;
final int posEnd = ...;
part.getEditorSite().getSelectionProvider().setSelection(
new TextSelection(posStart, posEnd - posStart));
For Java files it works fine, but for XML Schema (XSD), it doesn't. The editor opens, but no text is selected.
From debugging, I can tell that the part is of type org.eclipse.wst.xsd.ui.internal.editor.InternalXSDMultiPageEditor, and the selection manager is an org.eclipse.wst.xsd.ui.internal.adt.editor.CommonSelectionManager
I'm targetting Eclipse Mars and Neon, it does not seem to work for both.
What can I do to make it work? Or at least find some further information?
After having a look at the WTP code, this does not seem to be supported at the moment. But I found a workaround by explicitly checking if the editor is a multi part editor:
private static void setSelection(IEditorPart part, TextSelection textSelection) {
if (part instanceof MultiPageEditorPart) {
final MultiPageEditorPart multiPage = (MultiPageEditorPart) part;
for (final IEditorPart subPart : multiPage.findEditors(multiPage.getEditorInput())) {
setSelection(subPart, textSelection);
}
} else {
part.getEditorSite().getSelectionProvider().setSelection(textSelection);
}
}
I was not sure whether it is better to send the selection to all sub parts or only to one specific, but so far sending it to all seems to work.
Eclipse has an option in Indentation: "Alignment of fields in class declarations" that will
align assignments of class members as in:
class Foo {
int x = 3;
String y = "abc"
long z = 2;
}
Is there a setting that will do the same for method level assignments as in:
private void foo() {
int x = 3;
String y = "abc"
long z = 2;
}
I can not find such a setting.
Try creating a new Java Code Style Formatter profile (Window->Prefernces->Java->Code Style->Formatter) or modifying an older one and check Indentation and Braces tabs.
For future visitors.
There is no such option in Eclipse, but, as mentioned here, you can use plugin named OCDFormat that aligns assignments and declarations in a selected piece of code.
Installation: download the latest version of OCDFormat_*.jar from project page on github (click → Raw → Save as) and add it to your Eclipse plugins or dropins directory.
Usage: select a piece of code and press Ctrl+4.
The Eclipse code style formatter cannot align assignment statements.
columns4eclipse is plug-in that allows you to do so. I had made a gif video illustrating its use but my answer got deleted by a moderator (as >10k users will see), so I let you try the plug-in and see by yourself.
Eclipse's Search results view is quite handy with its tree-like structure. Is there any way to export these results to a readable text format or save them to a file for later use?
I've tried using copy & paste but the resulting text format is far from readable.
You can change the mode from tree to list by click 'upper-right corner triangle' ->'show in list', then just copy all the files in the list , it will be a perfect list of search result
I'm using Eclipse Search CSV Export.
No I don't think there is a possibility to export the results yet. (Update: Now there's a suitable plugin available). But you should be able to use the eclipse search framework programmatically an export the entries by yourself.
I did not test the following snipped but implemeted a custom search that way once (using the RetrieverAction class). You should be able to listen to search result changes without the action as well:
TextSearchQueryProvider provider= TextSearchQueryProvider.getPreferred();
// your input (you'll have to implement that one I think...)
TextSearchInput input = new TextSearchQueryProvider.TextSearchInput();
ISearchQuery query= provider.createQuery(input);
ISearchResult result = query.getSearchResult();
result.addListener(new ISearchResultListener() {
public void searchResultChanged(SearchResultEvent e) {
// -> export result
}
});
// run the query
NewSearchUI.runQueryInBackground(query);
Again: I did not test that at all and don't know if there is a better approach as well..
In my RCP app, I would like to point a property (osgi.java.profile) to a file, and would prefer using paths relative to my installation and config dir.
Is there a definitive spec on what kind of variables are supported in config.ini?
#config.dir seems to be supported, there are references in the builtin, and it's always mentioned as typical example (e.g this SO answer )
However, looking at docs like Eclipse help/Runtime Options, it mentions a few "symbolic locations" like #user.home; however that seems fairly limited and doesn't include #config.dir.
Have even dug into org.eclipse.osgi sources as well, and found no references to this (I did find LocationManager and its hard coded variable substitutions for #user.dir & co).
Can I refer to arbitrary system properties there in some way?
Is this #config.dir a special case, only handled by P2? UPDATE: this seems to be the case.. looking at Eclipse SDK, About .. Configuration dialog shows #config.dir unresolved, probably taken literally by the Equinox..
Thanks for any hints.
I'm late to the party, but hopefully this will help others in the future.
Starting with Eclipse 3.8/4.2 (June 2012), you can substitute Java properties and environment variables into your config.ini file (Eclipse Bug 241192). The Equinox launcher does not support substitution in the eclipse.ini launcher file. The syntax uses dollar signs ($VARIABLE$) to indicate variable substitution:
osgi.configuration.area=$APPDATA$/MyCompany/MyProgram/configuration
osgi.user.area=$APPDATA$/MyCompany/MyProgram/user
osgi.instance.area=$APPDATA$/MyCompany/MyProgram/instance
I imagine you could use something like this for your purposes:
osgi.java.profile=$osgi.install.area$/path/to/profile.txt
You can use a platform URL (Platform URI scheme) to achieve this, i.e.
osgi.java.profile = platform:/config/java_profile.txt
in config.ini, would point to the file java_profile.txt in the current configuration directory.
You might also use existing system properties in config.ini:
osgi.java.profile = ${osgi.configuration.area}/java_profile.txt
From org.eclipse.core.runtime.adaptor.LocationManager, here are the special tokens:
// Data mode constants for user, configuration and data locations.
private static final String NONE = "#none"; //$NON-NLS-1$
private static final String NO_DEFAULT = "#noDefault"; //$NON-NLS-1$
private static final String USER_HOME = "#user.home"; //$NON-NLS-1$
private static final String USER_DIR = "#user.dir"; //$NON-NLS-1$
Why not use two system property variables?
One is named -Dmy.relativepath=filename, which is processed by your code of relative path of eclipse installation folder(workspace or anywhere), another is called -Dmy.path=absolutepath.
The system property is passed to the jvm, you need some tricky(translate the variable in runtime) in the native launcher(like eclipse.exe) if you wants to use variable in its value.
Look how osgi.java.profile is resolved in org.eclipse.osgi.framework.internal.core.Framework:
// check for the java profile property for a url
String propJavaProfile = FrameworkProperties.getProperty(Constants.OSGI_JAVA_PROFILE);
if (propJavaProfile != null)
try {
// we assume a URL
url = new URL(propJavaProfile);
} catch (MalformedURLException e1) {
// try using a relative path in the system bundle
url = findInSystemBundle(propJavaProfile);
}
That means osgi.java.profile must point either to a fully qualified URL, or to a relative path in system bundle (org.eclipse.osgi). This makes impossible usage of installation directory relative path without patching Eclipse.
