Plugin stops detecting compiler flags after changing source files

[Spirarel]

Here's a small example

include prelude

type GraphNode[T] = ref object
  value: T
  neighbors: seq[GraphNode[T]]

iterator items[T](graphNode: GraphNode[T]): GraphNode[T] =
  var
    s = @[graphNode]
    seen = initHashSet[GraphNode[T]]()
    curr: GraphNode[T]
  while s.len > 0:
    curr = s.pop
    yield curr
    seen.incl curr
    for e in curr.neighbors:
      if e notin seen:
        s.add e

let nodes = GraphNode[int](value: 1, neighbors: @[GraphNode[int](value: 2, neighbors: @[])])

for i in nodes:
  echo i.value

compile with -d:nimPreviewHashRef

Restarting vscode and building on save. The code compiles and runs, there are no problems highlighted:

Add a few newlines to the end and build & run again. The code compiles and runs fine, but the plugin shows problems:

This greatly limits the plugin's usefulness.

extension: v0.9.0 vscode: 1.87.2 nim: 2.0.2

Sounds like the issue is that nimsuggest doesnt know about -d:nimPreviewHashRef. Create a config.nims and --d:nimPreviewHashRef to it Reopen if it doenst fix it.

Hmm I added this file with the entry to the directory; it's getting picked up by the build task, but the plugin is still showing issues. Does the extension require extra configuration?

[jmgomez]

No, it doesnt require extra configuration. Can you share your file structure? config.nims should be near the entry point

[Spirarel]

Essentially flat,

I mean the actual files with a minimal repro
