Support built-in completion #1
Description
Is your feature request related to a problem? Please describe
As a user I want to safely use built-ins available in FEEL.
Describe the solution you'd like
- Assist user in using built-ins by auto-completing them.
- (Optional) Assist in built-in variable completion
Describe alternatives you've considered
None.
Additional context
Built-in completion shall be extensible / optional as available built-ins depend on the environment (i.e. DMN FEEL standard vs. feel-scala, other implementation tool).
