VScode plugin not working well when the project has an incorrect or is missing a RASCAL.MF/.project file #1696

Closed leegbestand closed 2 years ago

LS,

Describe the bug

The VScode plugin does not work when the current project has no or an incorrect RASCAL.MF or .project file. Instead, it gives an internal error in the output console and a Request textDocument/documentSymbol error popup in the bottom right corner.

[Error - 10:31:17 PM] Request textDocument/documentSymbol failed.
  Message: Internal error.
  Code: -32603

To Reproduce

Steps to reproduce the behavior:

  1. Create a src/ directory in an empty directory
  2. Only create a rascal module file src/ directory
  3. Open VScode in the directory with the LSP plugin enabled and start typing.
  4. See the error dialogs pop-up in the right bottom corner.

Expected behavior I would expect it to work or a helpful error message indicating the requirement for the RASCAL.MF and .project file.

Desktop (please complete the following information):

** Additional context The minimal viable directory structure that seems to be working for me is the following:

.
├── META-INF
│   └── RASCAL.MF
└── src
    └── Something.rsc
DavyLandman commented 2 years ago

True, we should think about better feedback.

Workaround: It needs a pom.xml file. .project is not used.

In util::Reflective there is an a function that setups a project correctly: https://github.com/usethesource/rascal/blob/bec47a0fd41662c48d4851f80d92c32595094d9c/src/org/rascalmpl/library/util/Reflective.rsc#L315

leegbestand commented 2 years ago

Dear @DavyLandman ,

Thank you for the response. I tried to setup a new project using newRascalProject, but I still get the same behaviour. It seems that the RASCAL.MF file is missing the Manifest-Version entry. When I add this entry with a value, the error is gone. So, updating the RASCAL.MF to the following:

Manifest-Version: 0.0.1
Project-Name: se
Source: src/main/rascal
Require-Libraries:

works for me. I am not sure if the version has any effect? I tried several version and it seemed to have no effect.

jurgenvinju commented 2 years ago

ok. so when there is a MANIFEST.MF present in the same folder with a Manifest-Version: then everything works fine, but if the RASCAL.MF is alone, then it needs a Manifest-Version. weirdness

jurgenvinju commented 2 years ago

I've added Manifest-Version to the template. Considering this fixed for now, because letting the code work on broken RASCAL.MF files would require a lot of code.
