Read the contents of a project using an eclipse plugin - eclipse-plugin

I want to create a eclipse plugin which on click of a menu in the menu bar will scan all the project contents and give me idea about the use of a specified function if any such as isBoolean or isInteger etc..
I searched everywhere but not getting a clear idea about how to do it.I heard of IResource and Iproject API's but dint find any implementation of it.Could you please help me getting in the right direction .
I tried putting this in my action...
but got "java.lang.ClassNotFoundException: org.eclipse.jdt.core.search.SearchRequestor"
SearchPattern pattern = SearchPattern.createPattern("isBool",
IJavaSearchConstants.METHOD,
IJavaSearchConstants.REFERENCES,
SearchPattern.R_EXACT_MATCH);
IJavaSearchScope scope = SearchEngine.createWorkspaceScope();
SearchRequestor requestor = new SearchRequestor() {
#Override
public void acceptSearchMatch(SearchMatch searchMatch) throws CoreException {
// TODO Auto-generated method stub
System.out.println( searchMatch.getElement());
}
};
SearchEngine searchEngine = new SearchEngine();
try {
searchEngine.search(
pattern,
new SearchParticipant[]
{SearchEngine.getDefaultSearchParticipant()},
scope, requestor, null);
} catch (CoreException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Am I proceeding in the right direction? Or is there any changes need to be made..

I am assuming that you mean a Java project. You should have a look at the org.eclipse.jdt.core.search.SearchEngine API.
You need to do something like this:
SearchPattern pattern = SearchPattern.createPattern("isBoolean", IJavaSearchConstants.METHOD, IJavaSearchConstants.REFERENCES, SearchPattern.EXACT_MATCH);
new SearchEngine().search(
SearchEngine.createJavaSearchScope(patter,
new SearchParticipant[] { SearchEngine.getDefaultSearchParticipant() },
new IJavaElement[] { iJavaProject }),
requestor,
new NullProgressMonitor());
Where requestor is the thing that asynchronously receives (and processes) your match results.

Apache ISIS external link

Let's say I have a domain object Customer. On this object I have an address to an external site.
#PropertyLayout(named = "Link", describedAs = "Clickable link to customer")
public String getLink() {
return "http://www.customer.com";
}
In this case this will be shown as just text on the webpage. How do I create a clickable link in the wicket viewer from this?
There is a third-party extension: https://github.com/kev-m/isis-wicket-url/
This was done by Kevin Meyer, one of our committers.
I've raised https://issues.apache.org/jira/browse/ISIS-1616 to incorporate this into the framework "proper".
Meantime, you can add an action to open the link easily enough
#Action(semantics=SemanticsOf.SAFE)
#MemberOrder(named="link", sequence="1")
public java.net.URL openLink() throws MalformedURLException {
return new java.net.URL(getLink());
}
and just to finish it off, you could add this guard:
public String disableOpenLink() {
if(getLink() == null) { return "no link to open."; }
try {
openLink();
} catch(MalformedURLException ex) {
return "Bad link";
}
return null;
}
I don't think there is out of the box solution in Apache Isis for this.
You will need to roll your own Wicket component for it. For example, annotate this property with custom annotation #ExternalLink and then register a ComponentFactory that creates Wicket ExternalLink component for this property. See https://github.com/isisaddons/isis-wicket-summernote/blob/master/cpt/src/main/java/META-INF/services/org.apache.isis.viewer.wicket.ui.ComponentFactory for example.

Combining dataproviders TestNG

I have read a few stackoverflow posts about combining dataproviders but I cant't get anything to work.
What I'm currently doing is a selenium test that takes screenshots of every language the site is translated to.
It simply clicks through every link while taking screenshots of it, then it switches the URL to another language and repeat.
My problem is when doing this I can't redirect my screenshots to a specific folder per "language test". To do this I need a second dataprovider, but I already have a dataprovider for this test method for running a different URL per test.
So I need to combine these two dataproviders somehow.
They currently look like this
public static Object [][] language(){
return new Object[][]{
{"https://admin-t1.taxicaller.net/login/admin.php?lang=en"},
{"https://admin-t1.taxicaller.net/login/admin.php?lang=sv"},
};
}
public static Object [][] directory(){
return new Object[][]{
{"screenshotsEnglish.dir"},
{"screenshotsSwedish.dir"},
};
}
In my test class I just want to reach these two by writing
driver.get(**url**);
// This is the screenshot method. Where "Directory" is written I decide where to save the screenshots
Properties settings = PropertiesLoader.fromResource("settings.properties");
String screenshotDir = settings.getProperty(**directory**);
screenShooter = new ScreenShooter(driver, screenshotDir, "en");
Hope I have made myself clear, appreciate all help!
Regards
public static Object[][] dp() {
return new Object[][]{
{
"https://admin-t1.taxicaller.net/login/admin.php?lang=en",
"screenshotsEnglish.dir"
},
{
"https://admin-t1.taxicaller.net/login/admin.php?lang=sv",
"screenshotsSwedish.dir"
}
};
}
#Test(dataProvider = "dp")
public void t(String url, String directory) {
driver.get(url);
Properties settings = PropertiesLoader.fromResource("settings.properties");
String screenshotDir = settings.getProperty(directory);
screenShooter = new ScreenShooter(driver, screenshotDir, "en");
/*...*/
}

How do I get Xtext's model from a different plugin?

I've written an Xtext-based plugin for some language. I'm now interested in creating a new independent view (as a separate plugin, though it requires my first plugin), which will interact with the currently-active DSL document - and specifically, interact with the model Xtext parsed (I think it's called the Ecore model?). How do I approach this?
I saw I can get an instance of XtextEditor if I do something like this when initializing my view:
getSite().getPage().addPartListener(new MyListener());
And then, in MyListener, override partActivated and partInputChanged to get an IWorkbenchPartReference, which is a reference to the XtextEditor. But what do I do from here? Is this even the right approach to this problem? Should I instead use some notification functionality from the Xtext side?
Found it out! First, you need an actual document:
IXtextDocument doc = editor.getDocument();
Then, if you want to access the model:
doc.modify(new IUnitOfWork.Void<XtextResource>() { // Can also use just IUnitOfWork
#Override public void process(XtextResource state) throws Exception {
...
}
});
And if you want to get live updates whenever it changes:
doc.addModelListener(new IXtextModelListener() {
#Override public void modelChanged(XtextResource resource) {
for (EObject model : resource.getContent()) {
...
}
}
});

How do I use Sitecore.Data.Serialization.Manager.LoadItem(path,LoadOptions) to restore a item to Sitecore?

I am trying to use the sitecore API to serialize and restore sitecore items. I have created a WCF app to retrieve an Item name given a ID or sitecore path (/sitecore/content/home), retrieve a list of the names of the items children give an id or path. I can also Serialize the content tree.
public void BackupItemTree(string id)
{
Database db = Sitecore.Configuration.Factory.GetDatabase("master");
Item itm = db.GetItem(id);
Sitecore.Data.Serialization.Manager.DumpTree(itm);
}
The above code works great. After running it can see that the content tree has been serialized.
However when I try to restore the serialized items useing the following:
public void RestoreItemTree(string path)
{
try
{
using (new Sitecore.SecurityModel.SecurityDisabler())
{
Database db = Sitecore.Configuration.Factory.GetDatabase("master");
Data.Serialization.LoadOptions opt = new Data.Serialization.LoadOptions(db);
opt.ForceUpdate = true;
Sitecore.Data.Serialization.Manager.LoadItem(path, opt);
//Sitecore.Data.Serialization.Manager.LoadTree(path, opt);
}
}
catch (Exception ex)
{
throw ex;
}
}
With this code I get no errors. It runs, but if I check SiteCore it didn't do anything. I have tested using the Office Core example. The path I sent in, which might be the issue is:
C:\inetpub\wwwroot\sitecoretest\Data\serialization\master\sitecore\content\Home\Standard-Items\Teasers\Our-Clients.item
and
C:\inetpub\wwwroot\sitecorebfahnestockinet\Data\serialization\master\sitecore\content\Home\Standard-Items\Teasers\Our-Clients
Neither seems to do anything. I changed the teaser title of the item and am trying to restore to before the but every time the change is still present.
Any help would be appreciated as the SiteCore documentation is very limited.
You can always check how the Sitecore code works using Reflector, the following method is called when you click "Revert Item" in back-end:
protected virtual Item LoadItem(Item item, LoadOptions options)
{
Assert.ArgumentNotNull(item, "item");
return Manager.LoadItem(PathUtils.GetFilePath(new ItemReference(item).ToString()), options);
}
In LoadOptions you can specify whether you want to overwrite ("Revert Item") or just update ("Update Item") it.
See Sitecore.Shell.Framework.Commands.Serialization.LoadItemCommand for more info.
You have the correct LoadOptions for forcing an overwrite (aka Revert).
I suspect that the path you are using for the .item file wrong. I would suggest modifying your method to take a path to a Sitecore item. Using that path, you should leverage other serialization APIs to determine where the file should be.
public void RestoreItemTree(string itemPath)
{
Sitecore.Data.Database db = Sitecore.Configuration.Factory.GetDatabase("master");
Sitecore.Data.Serialization.ItemReference itemReference = new Sitecore.Data.Serialization.ItemReference(db.Name, itemPath);
string path = Sitecore.Data.Serialization.PathUtils.GetFilePath(itemReference.ToString());
Sitecore.Data.Serialization.LoadOptions opt = new Sitecore.Data.Serialization.LoadOptions(db);
opt.ForceUpdate = true;
using (new Sitecore.SecurityModel.SecurityDisabler())
{
Sitecore.Data.Serialization.Manager.LoadItem(path, opt);
}
}
Took me a while to work out, but you have to remove .item when restoring the tree
try this
public void RestoreItemTree(string itemPath)
{
var db = Factory.GetDatabase("master");
var itemReference = new ItemReference(db.Name, itemPath);
var path = PathUtils.GetFilePath(itemReference.ToString());
if (!System.IO.File.Exists(path))
{
throw new Exception("File not found " + path);
}
var opt = new LoadOptions(db);
opt.ForceUpdate = true;
using (new SecurityDisabler())
{
Manager.LoadItem(path, opt);
Manager.LoadTree(path.Replace(".item", ""), opt);
}
}

Serialize an Activity to xaml

I have Googled a bit, and cannot seem to find any examples of Xaml-fying Activities - good, bad, or otherwise!
public static string ToXaml (this Activity activity)
{
// i would use ActivityXamlServices to go from Xaml
// to activity, but how to go other way? documentation
// is slim, and cannot infer proper usage of
// ActivityXamlServices from Xml remarks :S
string xaml = string.Empty;
return xaml;
}
Hints, tips, pointers would be welcome :)
NOTE: so found this. Will work through and update once working. Anyone wanna beat me to the punch, by all means. Better yet, if you can find a way to be rid of WorkflowDesigner, seems odd it is required.
Alright, so worked through this forum posting.
You may Xaml-fy [ie transform an instance to declarative Xaml] a well-known Activity via
public static string ToXaml (this Activity activity)
{
StringBuilder xaml = new StringBuilder ();
using (XmlWriter xmlWriter = XmlWriter.Create (
xaml,
new XmlWriterSettings { Indent = true, OmitXmlDeclaration = true, }))
using (XamlWriter xamlWriter = new XamlXmlWriter (
xmlWriter,
new XamlSchemaContext ()))
using (XamlWriter xamlServicesWriter =
ActivityXamlServices.CreateBuilderWriter (xamlWriter))
{
ActivityBuilder activityBuilder = new ActivityBuilder
{
Implementation = activity
};
XamlServices.Save (xamlServicesWriter, activityBuilder);
}
return xaml.ToString ();
}
Your Xaml may contain certain artifacts, such as references to System.Activities.Presentation namespace appearing as xmlns:sap="...". If this presents an issue in your solution, read the source link above - there is a means to inject directives to ignore unrecognized namespaces.
Will leave this open for a while. If anyone can find a better solution, or improve upon this, please by all means :)
How about XamlServices.Save(filename, activity)?
Based on the other solution (for VS2010B2) and some Reflectoring, I found a solution for VS2010RC. Since XamlWriter is abstract in the RC, the new way to serialize an activity tree is this:
public static string ToXaml (this Activity activity)
{
var xamlBuilder = new StringBuilder();
var xmlWriter = XmlWriter.Create(xamlBuilder,
new XmlWriterSettings { Indent = true, OmitXmlDeclaration = true });
using (xmlWriter)
{
var xamlXmlWriter =
new XamlXmlWriter(xmlWriter, new XamlSchemaContext());
using (xamlXmlWriter)
{
XamlWriter xamlWriter =
ActivityXamlServices.CreateBuilderWriter(xamlXmlWriter);
using (xamlWriter)
{
var activityBuilder =
new ActivityBuilder { Implementation = sequence };
XamlServices.Save(xamlWriter, activityBuilder);
}
}
}
return xamlBuilder.ToString();
}
