I think this is just language detection kicking in. The DA doesn't transmit any information about the language of a source, and there's no field in DAP to do so.
You can easily validate that this isn't a language auto-detector problem alone, because when you Select All on the source file and copy that code into a blank file, then it's correctly detected as TypeScript.
@connor4312 did you see this? Also, since there's a .ts
that shouldn't trigger ML auto-detection... though that, plus the first line in the file may trigger our regular ol' heuristic language detection.
Maybe we need @bpasero. @connor4312 how do you open this file?
If it matters, here's the file itself: https://github.com/jridgewell/sourcemap-codec/blob/main/src/sourcemap-codec.ts
The first few lines are obviously TS (or, I guess, Flow):
export type SourceMapSegment =
| [number]
| [number, number, number, number]
| [number, number, number, number, number];
export type SourceMapLine = SourceMapSegment[];
export type SourceMapMappings = SourceMapLine[];
One thing that's interesting: in this case, the sourcemap of @jridgewell/sourcemap-codec
doesn't actually contain inline sources. Instead, inline sources when I debug my repro app seem to be loaded from a babel cache file in node_modules/.cache/babel-loader/f5c33fcf22e4d574d33ab842ee358fbac9d9eada3313c74bced334cb92e865d4.json
.
I don't think this changes the behavior though. I've seen the same behavior in other packages that do include sources content inside the sourcemap file but don't include source files in the package. For example, I reproed the problem while testing a PR in the @js-temporal/polyfill repo that I help to maintain. The specific commit which exhibited the problem was this one: https://github.com/js-temporal/temporal-polyfill/pull/194/commits/4a6348bf39204c4064826573fb08451153b08874. Later commits in this PR won't repro the problem, because we added the source files to files
in package.json.
Let me know if I can be helpful to repro this for you.
ah, missed that. I don't see where we set the mode for debug resources. @roblourens do you know?
js-debug has just been hardcoding text/javascript
🤦 But we don't really know, we should let the editor makes its best guess instead of reimplementing that logic ourselves.
I'm getting "plain text" for node internal files now. "Auto detect" picks javascript if I run it manually but I think it only runs automatically on untitled files?
What happened to the file extension?
Ah, right. We do need to have the mimtype for those.
What happened to the file extension?
Those just come in as a source with a URL like node:internal/fs
without an extension.
Type: Bug
When the VS Code JS debugger loads a source-mapped file, language auto-detection only works if the source file shown in the IDE debugger is loaded from a source file in
node_modules
. However, if the source file shown in the IDE is loaded via code in an inline sourcemap, then the file will be detected as JS, even if the filename in the sourcemap has a.ts
extension and would be detected as TS code if pasted into an empty file.Repro:
npx create-react-app sourcemap-debug --template typescript
cd sourcemap-debug
npm start
node_modules/@jridgewell/sourcemap-codec/src/sourcemap-codec.ts
to something else, e.g.node_modules/@jridgewell/sourcemap-codec/src/sourcemap-codec.ts.hide
. This will force VSCode to load the source from this package's inline sourcemap instead.Expected: Library's source file, like it was before, is detected as TS
Actual: Library's source file
sourcemap_codec.ts
is detected as JS, and there's a lot of errors shown in the Problems pane because TS code isn't valid JS.You can easily validate that this isn't a language auto-detector problem alone, because when you Select All on the source file and copy that code into a blank file, then it's correctly detected as TypeScript.
