My proposal was to make rule and fragment calls distinguishable. > I wouldn't change the syntax because a parser rule can be without assignment as well (unassigned rule call, see...

Collecting AST nodes within the TypeGraph for minimizing duplicated symbol lookup

1

We could collect all type and property information in a graph TOGETHER WITH the AST nodes which are contributing to that type or property. Types and properties could be nodes...

Base types should not pollute sub-types with mandatory attributes

1

### The setup I have an example grammar: ``` grammar HelloWorld entry Rule: {infer SubRule}name=ID|age=NUM; hidden terminal WS: /\s+/; terminal NUM: /[0-9]+/; terminal ID: /[_a-zA-Z][\w_]*/; ``` Which generates the following...

At some places we have tests where the entire case is encapsulated in a function and the test case is written as `await findXYZ({param1: 123, ...})` . Examples: [Hover tests](https://github.com/langium/langium/blob/main/packages/langium/test/lsp/hover.test.ts)...

1. Create file `docker-compose.yml`: ```yaml version: "2" services: spacyapi: image: jgontrum/spacyapi:en_v2 ports: - "127.0.0.1:8080:80" restart: always ``` 2. Execute `docker-compose up` 3. Visit `GET /en/schema` Result: ``` { "title": "Schema...

Langium misses some information when using declared types together with rule fragments. When the fragment is providing properties, there should be some hint, that the interface is not complete and...

`Maximum call stack size exceeded` because of missing assignments

1

Langium version: 2.0.1 ## Steps To Reproduce I tried to create a new grammar, copy-pasting from an ANTLR grammar. I was about to assign property names. The first rule in...

Export to EBNF grammar for ISLa together with ISLa constraints

2

If Langium would support the export to [EBNF](https://en.wikipedia.org/wiki/Extended_Backus–Naur_form), we would be able to use other tools as well. One of these tools would be [ISLa](https://github.com/rindPHI/isla) - a tool for generating...

Use 'Go to type definition' to switch to the generated AST type declaration

4

When you are in the grammar and want to know how the type looks like in the `ast.ts` file, we could use `Go to implementation` of the LSP. Especially when...
