Core: rule files in eclipse

[irina-dragoste]

• integrate rule files into eclipse (syntax highlighting, auto-completion, auto-suggest, refactoring, auto-formatting, etc), all functionalities that are available for Java syntax

[irina-dragoste]

• look into LanguageServer
• does LanguageServer need a port?
• see if there are LanguageServer tutorials
• eclipse marketplace plugins for simple languages (prolog, cdt, etc), preferably up to date, look at their code
• separate code that has to do with behaviour (auto-suggest, refactoring) from coupling to eclipse code

This is a plugin that can be used to construct a language, it seems reliable and a lot of people are using it, maybe if someone thinks it is relatable we can proceed.

this is also a plugin for eclipse3 that supports introducing a new language and it has syntax highlighting, it might be an option to consider as well.

Update: I guess this might turn out to be really useful.

It seems to me that Xtext would be the way to go: it's an actively maintained part of the eclipse platform, designed specifically to build eclipse plugins for new languages, and it can also generate a language server.

https://wiki.eclipse.org/FAQ_How_do_I_provide_syntax_coloring_in_an_editor%3F this might be an easy way to do syntax highlighting within eclipse using the parser we currently have as far as I understand, need to confirm this as well.

It's not, it requires writing a platform plugin and implementing a custom editor (both of which are taken care of by xtext), and it also doesn't work with our current parser.

A note: Xtext doesn't provide syntax highlighting in case of integrating it with LSP.
cf: eclipse/xtext-core#283

[alloka]

https://www.eclipse.org/Xtext/documentation/310_eclipse_support.html#highlighting This contains the features found in Xtext including refactoring, further elaborating tutorials are needed.

To clarify: the language server doesn't do syntax highlighting. The generated eclipse plugin still does.

Xtext Documentation

[mmarx]

I have removed the link. Please don't upload random documents you find on the Internet to the issue tracker, especially if it's unclear what license the content is under, if any. It doesn't help that that particular version of the documentation refers to an eight-year-old version of Xtext.

The current version of the Xtext documentation is found here: https://www.eclipse.org/Xtext/documentation/index.html

[alloka]

Is this way possible for us to get a standalone application?

https://github.com/echebbi/standalone-xtext-example#4-use-xtext-in-a-standalone-application
Update: How about this as well?
https://www.eclipse.org/Xtext/documentation/350_continuous_integration.html

[alloka]

I figured out a way which is to export the xtext project as a feature and it can be installed in any eclipse and it is working and tested, another way but not test is through maven.
