What happened?
I use Biome to lint and format a Svelte component library: https://github.com/carbon-design-system/carbon-components-svelte
Repro: carbon-design-system/carbon-components-svelte#2439
When upgrading to Biome 2.3.7 or later, I experience a benign diagnostic, which flags TreeViewNode.svelte:
$ biome check --write .
⚠ Biome encountered an unusually large amount of types which exceeded the limit of 200,000.
Either you are analyzing very large files (did you make sure to exclude your build/ or dist/ folder?), or you've encountered a bug in Biome.
Please follow these instructions to discover if you are accidentally analyzing large files and what to do about them in the relative guide.
ℹ In the meantime, you can force this file to be ignored using a `!!` pattern in the files.includes option in your configuration file.
ℹ Refer to the documentation for more information.
ℹ If you think this is a bug, please report it and include the following information:
- source code of the file;
- how the file is imported in the project (by a test file, a dependency, etc.);
- if and how the file/folder is excluded.
⚠ Failing to provide this information won't allow the team to fix the issue.
⚠ This diagnostic was derived from an internal Biome error. Potential bug, please report it if necessary.
Checked 1059 files in 585ms. No fixes applied.Through trial and error, the diagnostic disappears when commenting out the following code in the Svelte context script:
This diagnostic disappears when I comment out the following line:
<script context="module">
export function computeTreeLeafDepth(node) {
let depth = 0;
if (node == null) return depth;
let parentNode = node.parentNode;
while (parentNode != null && parentNode.getAttribute("role") !== "tree") {
- parentNode = parentNode.parentNode;
if (parentNode.tagName === "LI") depth++;
}
return depth;
}
</script>This diagnostic is not reproducible in the Biome playground, since it seems related to the config files.includes.
Expected result
It should not print out the benign diagnostic warning message.
Biome 2.3.6: no error
Biome 2.3.7: with error
Biome 2.3.10: with error
