Description

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Windows WSL

What is the issue affecting?

Annotations

Expected Behaviour

Attributes should be correctly parsed when they wrap over multiple lines.

Actual Behaviour

In VSCode:

---@param foo integer This is a long description that wrongs over multiple lines
---but is misinterpreted.
function x(foo) end

Image

---@param foo integer
---
---Long description with multiple paragraphs, and a code example:
---
---Usage:
---```lua
---local result = x(5)
---```
function x(foo) end

Image

Reproduction steps

Paste code above into VSCode.

Additional Notes

Surely it should be possible to write more than a single line of description for a parameter (and other tags).

Research direction

Reproduce the behavior in the VSCode extension using the Lua snippets in the report, then trace the annotation parsing path for multiline @param descriptions. Done means wrapped text, paragraph breaks, and the shown code example are retained correctly. The report names no source file or test, so locating the parser and existing annotation tests is part of the work.
