I want to write a CSS file into the preference store instead of into a local file path and read back whenever it requires.
I am new to Eclipse, an example would be helpful for me...
The preference store is for fairly small values stored using a 'key' and a 'value'. You could put the contents of the file as a 'value' but this is probably not a good use of the store.
Eclipse plugins can use the 'state location' to save files. Use something like:
Bundle bundle = FrameworkUtil.getBundle(getClass());
IPath path = Platform.getStateLocation(bundle);
File dir = path.toFile();
to get the path to the state location directory. Your plugin can store anything it likes in this directory,
Platform is org.eclipse.core.runtime.Platform
The preference store is for key-value-pairs, not for files.

I'm building an app with react-native, and I'm trying to use the react-native-fs module to list out a series of images located in the app folder. The images are located in a folder in the app project folder named 'data', so for example if I want to display one of the images, this works:
<Image source={require('./data/boo.png')} />
However when I try to use react-native-fs to list out all the files in that folder like so:
RNFS.readdir(RNFS.DocumentDirectoryPath+'/data')
.then((result) => {
console.log('GOT RESULT', result);
})
.catch((err) => {
console.log(err.message, err.code);
});
I get the error 'Folder does not exist'. Also when I remove the +'/data' the only result listed is a file by the name of 'ReactNativeDevBundle.js', with a path of '/data/user/0/com.awesomeproject/files/ReactNativeDevBundle.js'. Is this the expected behavior? If this is the expected behavior, and I am doing something wrong, how can I access the file folder I want from within the app? Side question, if I wanted to provide that Image tag with an absolute path, what would that look like.
First, are you creating the data folder in running time? or why do you think that's where the files are?
Second,
Also when I remove the +'/data' the only result listed is a file by
the name of 'ReactNativeDevBundle.js', with a path of
'/data/user/0/com.awesomeproject/files/ReactNativeDevBundle.js'. Is

Yes, this is the expected behavior, RNFS.DocumentDirectoryPath goes directly to /data/user/0/com.awesomeproject/files/, this is where you should create the data folder if you want to keep using the same code you currently have
EDIT:
According to one of the contributors of the package: if your folder is within the javascript-space this package won't work.
If you're using android, you may need to put the files into the assets-folder within the android-folder. Then you should be able to use readDirAssets.
I recommend to read Differences between File Source
Excerpt:
Normal Files: These files are created by your app using fs, or fetch API, you can do any operation on these files.
Asset Files: Compiled into the app bundle so generally they're on
readonly mode
I'm trying to change the eglfs mouse cursor graphics for my embedded linux QT application (QT5.5). I have the new cursor atlas PNG and the new JSON descriptor file, but the documentation is rather vague:
".. a custom cursor atlas can be provided by setting the QT_QPA_EGLFS_CURSOR environment variable to the name of a JSON file. The file can also be embedded into the application via Qt's resource system."
I'd prefer to keep everything within the resource system if possible but I can't work out how to do it.. do I need a specific qrc file containing the path to the JSON file? I assume that the PNG file would also need to be added as a resource so that it gets built into the application?
If adding it via the resource system is a bad idea where's the correct place to set the QT_QPA_EGLFS_CURSOR environment variable? I'm currently specifying the platform on the command line via "-platform eglfs"; will this be ok or will I need to set the platform to eglfs in the build?
After much trial, error and digging around I have found the solution that I was looking for within the resource system.
Create a new resource file called "cursor.qrc", the contents of which needs to be two lines:
path/to/your/custom-cursor-atlas.png
cursor.json
The first line (path to your cursor atlas) must be relative to your resource directory.
You then need to put the JSON file (contents as described in the documentation) in the root of your resource directory. It must be called "cursor.json", and its image location line must must match the location in your new resource file and be of the format:
"image": ":/path/to/your/custom-cursor-atlas.png",
This will then include your cursor atlas in resources, and Qt will find it when your application starts.
Run time solution example:
export XDG_RUNTIME_DIR=~
export QT_QPA_EGLFS_CURSOR=~/cursor.json
In the cursor.json:
"image": "cursor.png",
Put your custom cursor.png atlas into your home dir (~) then run the Qt app from there.
Live templates -> edit variable.
I can specify groovy file in variable settings: groovyScript("C:/test.groovy")
Where is "home" directory to store my script? i Want something like that:
groovyScript("test.groovy")
For easy export config to another PC.
groovyScript's argument can be either the script text itself or a filename. In the latter case the filename is relative to idea or idea/bin directory. It's probably better to use absolute paths.
In recent IDEA builds you can share live templates by copying them to clipboard (Ctrl+C, see https://youtrack.jetbrains.com/issue/IDEA-141077)
We are trying to use Apache PropertiesConfiguration in our project using JSF and JBoss.
My property file is located inside a package say demo.prop by the name of Prop1.prop
Inside my WAR file the same is present under /WEB-INF/classes/demo/prop/Prop1.prop
Using
FacesContext.getCurrentInstance().getExternalContext().getResource("/WEB-INF/classes/demo/prop/Prop1.prop");
I am able to fetch the property file. So when I try to extract a string from the property file using
PropertiesConfiguration pc1=new PropertiesConfiguration(a);
String s1=(String)pc1.getProperty("User_Name");
I am able to get the proper string. Using set property method I am able to set the property also.
pc1.setProperty("User_Name", "hardcodedString");
But I am not able to save the FILE back to this location. No matter what I do it is not able to save the file using pc1.save.
Can anyone please try to tell me how can I save this file back to its original location so that the changes done in the property file remain as it is.
Modifying the WAR file is a bad idea (for example, some web servers may notice the file
modification an redeploy your app, there may be problems when the server explodes the war on deployment etc.)
I would suggest applying an alternative approach - some possibilities are:
Place the properties in a database table, so they can be easily modified
Use an external properties file for overriding your "Prop1.prop" file settings. You can pull this off for example as follows. Assume that the default property values are bundled in your WAR and the modified values are saved to some other path, which is defined using a system property - let say it's called CONFIG_LOCATION. Now after loading your properties from the bundle you read them also from this external "overrides.prop" file - this overrides your defaults from "Prop1.prop":
PropertiesConfiguration pc1=new PropertiesConfiguration(a);
try(FileReader propReader = new FileReader(System.getenv().get("CONFIG_FILES") +"/overrides.prop"){
pc1.load(propReader);
}
When you need to save changes, you do that to "overrides.prop" - this will save all
the properties, not only the changed ones, but that should have no negative effects.
Assuming that my JS file is in /libs/qrcode/qrcode.js and i have another file qrcode.html at /libs/qrcode/, is it possible to get current directory/path (i.e. /libs/qrcode/) inside the qrcode.js?
what i'm trying to do is to load qrcode.html in the webview inside qrcode.js without worrying where is the qrcode folder reside in the Resource directory.
Any help?
Try Ti.Filesystem.resourcesDirectory or Ti.includeAbsolute
This should give you the path from your Resources folder or take a look at the Titanium.Filesystem.File
