Customizable formatting [message #1176567]

Hi everyone,
I've implemented some formatting rules in the provided extension of AbstractFormatter. Now my goal is to make it customizable by user. I've created a property page just with a check-box, and in the configureFormatting(FormattingConfig c) I check the corresponding property value for the checkbox and setNoLinewrap or singe linewrap based on the check result.
In debug I can see that property value is read correctly (if there is a tick - true and setLinewrap is executed, otherwise setNoLineWrap).

The problem is that property change has its effect only for the first two times - after I start eclipse with my editor and after first change of the property. Can somebody give a hint why is it so and what should I change to make it normal real-time adjustment without a need to restart eclipse?

Thanks in advance!

Hi,

have a look at org.eclipse.xtext.formatting.impl.FormattingConfig.
maybe you can null the once stored config.

I tried to null it, but it didn't help. What I did is created my own AbstractFormatter and from that one I inherit my XTend formatter.

In AbstractFormatter I did only one change from:

	protected synchronized FormattingConfig getConfig() {
		if (config.config == null) {
			config.config = createFormattingConfig();	
		        configureFormatting(config.config);
		}
		return config.config;
	}

to:

	protected synchronized FormattingConfig getConfig() {
		if (config.config == null) {
			config.config = createFormattingConfig();	
		}
		configureFormatting(config.config);
		return config.config;
	}

It didn't help as well.

Then I tried to also create it everytime:

	protected synchronized FormattingConfig getConfig() {
		if (config.config == null) {

		}
		config.config = createFormattingConfig();	
		configureFormatting(config.config);
		return config.config;
	}

Didn't help. Seems like problem is actually not even in formatter

Hi,

what does debugging say. is the formatter asked for a config? see org.eclipse.xtext.ui.editor.formatting.ContentFormatterFactory.FormattingUnitOfWork

Hi,
Yes it is asked for the config, config is assigned according to the new property value but after the second try content (edited source) is not changed anymore, i.e it keeps formatting style from the second try.
