requirement is to read message from IConsoleConstants.ID_CONSOLE_VIEW and write it into text file.
Say myConsole (of type MessageConsole) is the reference to your console. The below code will give you the required.
myConsole.getDocument().get();
I don't think you will be able to retreive a direct stream to read the console content. Note also that the console view may have multiple different consoles, you will have to retrieve the good one.
Retrieving the content displayed in a single console should be possible going through the IDocument of a TextConsole. You can get the whole text content. You could also have a look to the IDocumentListener if you can be notified of changes.
Another solution should be to go with a PatternMatchListener of the TextConsole directly.
Anyway I don't think there is a direct solution to do this with the Eclipse console API.

I have a VS Code extension which enforces a json schema onto a json file. When there is an error, it posts a message into the Problems window which is great.
How can I write to this window, from my extension, to put my own messages in the Problems window?
I have searched the docs, and could only find showInformationMessage, showErrorMessage and showWarningMessage but none of these put the message anywhere visible that I can see.
Any hints to the correct method or a suitable doc page would be most helpful.
You can use diagnostics for this. The starting point for that API is createDiagnosticCollection() from the vscode.languages namespace. vscode-extension-samples has a simple example for this. The basic idea is that DiagnosticCollection acts as a map with URIs as keys and arrays of diagnostics as values.
I just started playing with google chrome apps. I've searched the internet and haven't found the way to print the content of the windows. Tried using windows.print(), but nothing happened.
As far as I have read, the print() wont work since it is called in the background.html that does not have any content. How can I make the call at the correct place and send the content of the app to the printer?
Thank you in advance!
You're right that this can't be done through the Background page, since it is not rendered. What you'll need to do is inject a "content script" into the page you would like to print. The content script would contain the print command, and probably whatever would trigger the print command.
In a nutshell, "content scripts" are scripts that are injected into the pages a user browses. You can inject pretty much any JavaScript you like, and even inject entire JavaScript libraries like JQuery. More details can be found here:
https://developer.chrome.com/extensions/content_scripts.html
If you decide to use a popup window to trigger the print you can pass a message to the window you would like to print. Message passing is how the different components of an extension (background page, content script, popup) communicate. More info can be found here:

Printing in apps is not yet supported, I believe. See

I'm investigating whether I can get better performance from asl_log than NSLog on iPhone/iOS (probably...) but I'm stuck at a point where it doesn't seem that asl's log output will show up in the System Console (as viewable by a number of apps like System Console, iConsole, etc). I know that I'm setting it up right since I open with ASL_OPT_STDERR, and I see the log entries in XCode when the device is tethered.
I've explored lots of interesting stuff online (e.g. http://boredzo.org/blog/archives/2008-01-20/asl-logging, https://github.com/robbiehanson/CocoaLumberjack) and the best hope seemed to be asl_open() with Facility of "com.apple.console" but alas, the output still doesn't show up in Console. Is NSLog the only option?
Add STDERR to ASL and then it shows up in the console
asl_add_log_file(NULL, STDERR_FILENO);
You need to set read privileges on the message, using either ReadUID or ReadGID. Setting either to -1 will allow any user/group to view the message according to the header file documentation.
aslmsg msg = asl_new(ASL_TYPE_MSG);
asl_set(msg, ASL_KEY_READ_UID, "-1");
asl_log(NULL, msg, ASL_LEVEL_NOTICE, "Hello, world!");
asl_free(msg);
Are there any frameworks/services for logging user usage of an iphone application?
Say you want to log events like 'creating a contact' or something similiar, to know how people are actually using your app.
I have used and really like Pinch Media. (Recently renamed to flurry)

It gives you a bunch of analytics without you having to do anything special.
You can also add hooks to your code to see how often a particular section of code is run and get analytics on that area as well.
Yes, Flurry Analytics does this. You can even pass parameters to your events so you can break down which options are most popular, etc.
What you could do is simply log these messages perhaps as a Log custom class, and whenever you need to add anything to the log, you would simply add a new Log item to the AppDelegate or wherever you need to store the list of Logs. Then you can save them to the file system.
For achieving the logging the feature usage in flurry the url below can be helpful.

In our app we need to check if the data is saved when we are in a particular place before navigating away from it. So the user should be able to negate a browser back button request. But by the time that the history value change event is received the url has already been changed. The History class doesn't seem to have a way to restore the url back. Anybody have any ideas?
In GWT 2.1 you get Activities and Places. And activity has a maystop method, which is exactly what you want, if I understand you correctly.
Use a window.onunload or window.onbeforeunload javascript callback to confrim/save state.
onbeforeunload example
I haven't actually implemented this behavior yet, but here is my plan and maybe it will work for you.
1) Each time you receive an onHistoryChanged event and decide to allow it, save the current historyToken in an instance variable somewhere.
2) Keep track of activity on the page that should block navigation. Use a data structure that can keep track of multiple activities, like multiple file uploads, multiple edits, etc.
3) When you receive a new onHistoryChanged event, if your data structure from #2 indicates that it's not safe to navigate, avoid changing the page and restore the historyToken that you saved in #1. I'm assuming that you can do this either by:
a) Calling History.newItem(oldHistoryToken, false) or
b) Calling History.newItem(oldHistoryToken, true) and keeping a flag to force the next onHistoryChanged to be ignored.
Again, I haven't actually implemented this so let me know how it works out.
If you have links that allow the user to leave the app and you want to prevent that as well, you'll need to also add an onbeforeunload.
Have a look at the PlaceManagerImpl class from the gwt-platform framework. Especially the onValueChange() method and the methods dealing with the onLeaveQuestion field.
Hope that helps.
In this issue report, t.broyer explains in his comment that such behavior was planned during design of Places framework. The most important part is:
mayStop was a mistake, or it should have only been called when unloading the app, not for internal navigation within the app.
So probably it's better to not use it at all...
