Features

Search symbols in workspace

To search for symbols in the current workspace press Ctrl + Shift + T to open the search window. Now you can type what you are looking for. This currently only work in the context of an open flix editor. Alternatively you can press Ctrl + 3 and search for the Open Symbol (Flix) - Show a list of workspace-wide symbols command.

Search symbol references

Place the cursor on a symbol and press Ctrl + Shift + G. This should open the search view with a list of all places where the marked symbol is referenced from.

Select Flix version

To select the version of the Flix compiler that should be used, right click on a project, select Properties and then Flix Project.

If you want to use a custom Flix version that is not available on the list at the properties page then you can place the flix.jar file in the project root. The flix.jar will override the other Flix version preference.

The detection of the flix.jar file should happen automatically. In case of problems it will never be wrong to restart the IDE. Also be aware that a custom version can be incompatible with the IDE integration.
