How to use tinylog in Eclipse plugin [message #1826627]

Mon, 27 April 2020 20:19

Eclipse User

I am writing an Eclipse plugin and want to use tinylog in my plugin code. I tried this:

1). modified Eclipse config file (eclipse.ini) to add this line: -Dtinylog.configuration=C:\eclipse-cpp-2018-09-win32-x86_64\eclipse\tinylog.properties

2). content of tinylog.properties:

writer = file
writer.level = debug
writer.file = C:\eclipse-cpp-2018-09-win32-x86_64\eclipse\log.txt
writer.charset = UTF-8
writer.append = true
writer.buffered = true

In fact, not just tinylog in my plugin. I tried umlet Eclipse Plugin (https://www.umlet.com/. The plugin uses slf4j API and lib. I made its logging stmt executed (verified by JOptionPane popup). I couldn't find and file being created.

What is tinylog, and where is its documentation and forum? This one isn't really for general programming questions or third party libraries.

tinylog is a thirdparty lib (https://tinylog.org/v2/).

It looks like https://tinylog.org/v2/support/ directs you to Stack Overflow.

that's true but tinylog people seems they don't know Eclipse plugin very well. Not much help from there although I tried. Here I'd like to get direct advice on problem itself although more channels information is also good.

My same help request there if anyone want to check first:

Does it work when you use those properties in a normal Java application?

Just to be sure, you added the line -Dtinylog.configuration=C:\eclipse-cpp-2018-09-win32-x86_64\eclipse\tinylog.properties after the line with -vmargs on it? You've tested that System.getProperty("tinylog.configuration") returns the value you've configured?

According to my test, slf4j logging does not work in Eclipse plugin neither(https://github.com/umlet/umlet/issues/581). Looks like thirdparty logging lib usage in Eclipse plugin could be a pioneer effort.

I don't know what you've tryied, but SLF4J can actually be used in an Eclipse plugin, see this article on Vogella: https://www.vogella.com/tutorials/EclipseLogging/article.html#slf4j-in-eclipse-applications

thanks for the suggestion!
eclipse.ini :

-Dosgi.dataAreaRequiresExplicitInit=true
-Xms256m
-Xmx1024m
-Dbundles.configuration.location=configuration
--add-modules=ALL-SYSTEM

I modified my code to use JOptionPane to show
```
@Override
public Object execute(ExecutionEvent event) throws ExecutionException {
IWorkbenchWindow window = HandlerUtil.getActiveWorkbenchWindowChecked(event);
generateUTSrc(event);
return null;
}

public void generateUTSrc(ExecutionEvent event)
{
JOptionPane.showMessageDialog(null,System.getProperty("tinylog.configuration"));
Logger.debug("generateUTSrc");
....
}
```

please refer to latest update in https://stackoverflow.com/questions/61318315/how-to-use-tinylog-in-eclipse-plugin. Ok now.

A small issue is that although I set tinylog to flush immediately but I have to quit Eclipse before I can see log content in my log file. Any possible Eclipse setting I need to do?

So you have the log file open in an Eclipse editor but the editor is not updated even though the logger writes to the file, right?

A right click on the project > Refresh should do the trick. The issue is likely that Eclipse is never notified of any change in the file because the logger does not use Eclipse's resources API.

For a permanent solution you can force Eclipse IDE to use native polling to watch files (Windows > Preferences > General > Workspace > Refresh using native hooks or polling).

It does solve the small issue. BTW, what's the Eclipse Resource API doing logging?
