how to make a editor extened from XMLMultiPageEditorPart readonly - java-me

I have made an editor extending XMLMultiPageEditorPart
now im opening a xml file in this editor
i want to make this editor read only ,
IFile file1=file...
i want the xml file which is opened in the editor to be read only.

I just resolved it.
First: you should define Instance Class of IStorage and IStorageEditorInput,You can refer to How do I open an editor on something that is not a file?
Second: Define your own XMLEditor, like this:
public class XMLEditor extends XMLMultiPageEditorPart implements IStorage{}
Last: Call editor like this:
File file= new File( path );
IWorkbenchPage page = window.getActivePage();
IStorage storage = new FileStorage(file);
IStorageEditorInput input = new XMLInput( storage );
try {
page.openEditor(input, "Your ID");
} catch (PartInitException e) {
MessageDialog.openError(window.getShell(), "", path);
}
Note: in the class FileStorage, the function getName() should return the file full path, or you will get errors.
I Hope this can help you, if you have any problem, we can discuss it, use gtalk:vvvv.spring#gmail.com

Twig_Template::getSource() doesn't work until the template has been cached

I need to load and show a Twig template's source.
The template's getSource() method appears to work by using reflection to find its own class file, and reading the comment block at the end of it (which has the Twig code).
public function getSource()
{
$reflector = new ReflectionClass($this);
$file = $reflector->getFileName();
// ...
}
Unfortunately, that file is only available when the template is loaded from the file cache - before then, the class is defined at runtime and the ReflectionClass will return Environment.php(403) : eval()'d code as the class file.
if (!class_exists($cls, false)) {
$content = $this->compileSource($this->getLoader()->getSource($name), $name);
if ($this->bcWriteCacheFile) {
$this->writeCacheFile($key, $content);
} else {
$this->cache->write($key, $content);
}
eval('?>'.$content);
}
Is there any other way I can get the source from Twig, or is it only possible if I find and read the original .html.twig file directly?
Oops. The answer was right there in the code, of course:
$content = $this->compileSource($this->getLoader()->getSource($name), $name);
All I needed was to replace $environment->loadTemplate($name)->getSource() with $environment->getLoader()->getSource($name).

Revit Api Load Command - Auto Reload

I'm working with the revit api, and one of its problems is that it locks the .dll once the command's run. You have to exit revit before the command can be rebuilt, very time consuming.
After some research, I came across this post on GitHub, that streams the command .dll into memory, thus hiding it from Revit. Letting you rebuild the VS project as much as you like.
The AutoReload Class impliments the revit IExteneralCommand Class which is the link into the Revit Program.
But the AutoReload class hides the actual source DLL from revit. So revit can't lock the DLL and lets one rebuilt the source file.
Only problem is I cant figure out how to implement it, and have revit execute the command. I guess my C# general knowledge is still too limited.
I created an entry in the RevitAddin.addin manifest that points to the AutoReload Method command, but nothing happens.
I've tried to follow all the comments in the posted code, but nothing seems to work; and no luck finding a contact for the developer.
Found at: https://gist.github.com/6084730.git

{
_instance = instance;
}
}

}
There is an easier approach: Add-in Manager
Go to Revit Developer Center and download the Revit SDK, unzip/install it, the check at \Revit 2016 SDK\Add-In Manager folder. With this tool you can load/reload DLLs without having to modify your code.
There is also some additional information at this blog post.
this is how you can use the above code:
Create a new VS class project; name it anything (eg. AutoLoad)
Copy&Paste the above code in-between the namespace region
reference revitapi.dll & revitapiui.dll
Scroll down to AutoReloadExample class and replace the path to point
your dll
Replace "Mine.ExampleCommand" with your plugins namespace.mainclass
Build the solution
Create an .addin manifest to point this new loader (eg.
AutoLoad.dll)
your .addin should include "FullClassName" AutoLoad.AutoReloadExample
This method uses reflection to create an instance of your plugin and prevent Revit to lock your dll file! You can add more of your commands just by adding new classes like AutoReloadExample and point them with seperate .addin files.

groovy parse local html file

I am working on a groovy script that will get all the local html files and parse certain tags in them. I tried using something like html clean and it just is not working. I tried to read each line but that only works when the stuff I need is on 1 line. I have this script up on github, https://github.com/jrock2004/johns-octopress-scripts/blob/master/convertCompiledPosts/convertPosts.groovy. Thanks for any input
Edit: So I am getting closer. I have this code now
def parser = new org.cyberneko.html.parsers.SAXParser()
new XmlParser( parser ).parse( curFile+ "/index.html" ).with { page ->
page.'**'.DIV.grep { it.'#class'?.contains 'entry-content' }.each {
println it
println "--------------------------------"
}
}
And what it prints is
DIV[attributes={class=entry-content}; value=[P[attributes={}; value=[As an automation developer, I have learned how to write code in Java. When I am having an issue, one of the nice things that you can do is debug your code, line by line. For the longest I had wished that something like this existed in PHP. I have come to find out that you can actually debug code, like I do in Java. This is such a helpful task because I do not have to waste time using var_dump and such on variables or results. In your apache/php server you need to install and or enable something called, A[attributes={href=http://xdebug.org/}; value=[Xdebug]], . I will work on a tutorial on how to use xdebug while writing code in Sublime Text 2. So keep an eye out on my blog and or, A[attributes={href=http://www.youtube.com/jrock20041}; value=[YouTube]], channel for this tutorial.]]]]
So basically what I want is I wall the text including the html elements in the div with the class entry-content. If you want to see the page it can be found here -- http://jcwebconcepts.net/blog/2013/02/02/xdebug/
Thanks for your help
It does work... Save the HTML for this page to a file, then you can parse it.
The following code prints the name of the author of every comment on the page:
#Grab('net.sourceforge.nekohtml:nekohtml:1.9.16')
def parser = new org.cyberneko.html.parsers.SAXParser()
new XmlParser( parser ).parse( file ).with { page ->
page.'**'.A.grep { it.'#class'?.contains 'comment-user' }.each {
println it.text()
}
}
When file is set to be a File pointing to the saved HTML (or a String containing the URL of this question), it prints:
tim_yates
jrock2004
tim_yates
Edit:
To print the contents of a given node, you could do (using the example from your edited question):
#Grab('net.sourceforge.nekohtml:nekohtml:1.9.16')
import groovy.xml.*
def parser = new org.cyberneko.html.parsers.SAXParser()
new XmlParser( parser ).parse( 'http://jcwebconcepts.net/blog/2013/02/02/xdebug/' ).with { page ->
page.'**'.DIV.grep { it.'#class'?.contains 'entry-content' }.each { it ->
println XmlUtil.serialize( it )
}
}

GWT-GXT FileUploadField

I tried making a form in GXT to upload files, but I see more examples on the net, I failed to make it work a simple FileUploadField to save the file locally.
Cde fragment:
formPanel = new FormPanel();
formPanel.setBodyBorder(false);
formPanel.setHeaderVisible(false);
formPanel.setAction(GWT.getModuleBaseURL() + "fileUpload");
formPanel.setEncoding(Encoding.MULTIPART);
formPanel.setMethod(Method.POST);
formPanel.setButtonAlign(HorizontalAlignment.CENTER);
formPanel.setHeaderVisible(true);
fileUploadField = new FileUploadField();
fileUploadField.setName("fileName");
fileUploadField.setAllowBlank(false);
fileUploadField.setFieldLabel("Archivo");
fileUploadField.addListener(Events.OnChange, new Listener<BaseEvent>() {
public void handleEvent(BaseEvent BaseEvent) {
aSubmitButton.setEnabled(true);
}
});
aSubmitButton = new Button("OK");
aSubmitButton.setEnabled(false);
aSubmitButton.setId("submit_button");
aSubmitButton.addSelectionListener(new SelectionListener<ButtonEvent>() {
#Override
public void componentSelected(ButtonEvent inButtonEvent) {
formPanel.submit();
}
});
The above code is the declaration of FormPanel and FileUploadField.
We use gwtupload-0.6.3-compat.jar library to do the job.
Basically, the idea is that on the server side you need to create a servlet, which is going to be accepting your uploaded files. The mentioned library provides UploadAction servlet extension facilitating that.
On the client side you can use one of gwtupload components. We use MultiUploader for instance. That's literally a few lines of code there. Main code is in the listener:
private IUploader.OnFinishUploaderHandler onFinishUploaderHandler = new IUploader.OnFinishUploaderHandler() {
public void onFinish(IUploader uploader) {
if (uploader.getStatus() == Status.SUCCESS) {
// What you want to do when file is uploaded.
}
}
};
The rest is taken care of by the component. Since the library is for GWT, it comes with source code, so you can see what it's doing behind the scene and read extensive comments in the code.
Free to use of course.

How do I set an embedded Groovy scripts classpath?

I am trying to extend an Eclipse code builder (for generating DTOs from Hibernate VOs) - and it uses Groovy for its template system.
The code it uses to create the groovy Script is a little weird (not what I see in the Groovy docs) but it works, mostly:
GroovyShell shell = new GroovyShell();
script = shell.parse(source);
Then, later:
Binding binding = (bindings == null ? new Binding() : new Binding(bindings));
Script scriptInstance = InvokerHelper.createScript(script.getClass(), binding);
scriptInstance.setProperty("out", out);
scriptInstance.run();
out.flush();
Now, this works just fine, until it hits a reference to an object that is not directly in the project. In the script, it iterates through the properties of the Class that it is processing - when it does this, Groovy looks at all of the methods and when it can't find a Class definition for one of the method parameters, it craps out. In this case, it's dying when it finds any references to Hibernate, but I'm sure it will crap out with a lot more. It doesn't need to do anything to them, but it can't live without knowing what they are apparently.
Script doesn't appear to have a classloader that I can supply any classpath info, so I tried providing it to the GroovyShell - no difference.
What's the proper way to fix this so that the Groovy interpreter can find my projects referenced Jars?
I had this exact problem and solved it by creating my own URLClassLoader, and using reflection to call a protected method to add a new path to the ClassPath
// Specify the path you want to add
URL url = new URL("file://path/to/classes/here");
// Create a new class loader as a child of the default system class loader
ClassLoader loader = new URLClassLoader(System.getClass().getClassLoader());
// Get the AddURL method and call it
Method method = URLClassLoader.class.getDeclaredMethod("addURL",new Class[]{URL.class});
method.setAccessible(true);
method.invoke(loader,new Object[]{ url });
GroovyShell shell = new GroovyShell( loader );
The same as #James can be done without using reflection, loading all jar files from a certain folder:
URLClassLoader classLoader = new URLClassLoader( getExtraJarUrls(), getClass().getClassLoader() );
GroovyShell shell = new GroovyShell( classLoader, binding, compilerConfiguration );
private URL[] getExtraJarUrls() throws MalformedURLException
{
logger.debug( "Loading extra jars from {}", EXTRA_JARS_DIR.getAbsolutePath() );
URL[] result;
File[] files = EXTRA_JARS_DIR.listFiles( new JarFilenameFilter() );
if (files != null)
{
List<URL> urls = new ArrayList<URL>( files.length );
for (File file : files)
{
urls.add( file.toURI().toURL() );
}
result = urls.toArray( new URL[urls.size()] );
}
else
{
result = new URL[0];
}
logger.debug( "Adding URLs to classloader: {}", Arrays.toString( result ) );
return result;
}
private static class JarFilenameFilter implements FilenameFilter
{
public boolean accept( File dir, String name )
{
return name.endsWith( ".jar" );
}
}
I'm having the same problem trying to automate Gant scripts running. The solution I found is:
copy gant-starter.conf (or
groovy-starter.conf if it's just
groovy) from $GROOVY_HOME/conf to your
own dir;
add "load [directory]" or
"load [jar]" there, as described in
javadocs to
org.codehaus.groovy.tools.LoaderConfiguration,
found in Groovy source distribution;
before starting groovy set
groovy.starter.conf.override system
property to the name of that file,
like
-Dgroovy.starter.conf.override=[filename]
