Links/Samples where language auto-detection doesn't work

[TylerLeonhardt]

This issue is just to enumerate samples and things where auto-detect didn't work and why. There's likely not much that can be done beyond totally retraining the ML model... but at least we can have them in one place.

Some C examples don't work for me, but it could be because it's just too short: https://www.programiz.com/c-programming/examples/add-numbers

This JS example was detected as TS: https://www.programiz.com/javascript/examples/positive-negative-zero

Tried auto-detection with a large JSON file and it wasn't able to detect it as JSON, just kept as "plain text": https://github.com/zemirco/sf-city-lots-json/blob/master/citylots.json

I've had trouble getting Python code to be recognized. For example, using code from this example site, this code remains plain text:

# Import re module
import re

# Take any string data
string = input("Enter a string value: ")
# Define the searching pattern
pattern = '^[A-Z]'

# match the pattern with input value
found = re.match(pattern, string)

# Print message based on the return value
if found:
  print("The input value is started with the capital letter")
else:
  print("You have to type string start with the capital letter")

Extension-less bazel BUILD files are detected as either Python, Javascript, Julia or Lua.

Example BUILD file (this currently resolves to Julia for me):

load("//tooling/bazel:defs.bzl", "stage", "codeowners", "ecs_deploy")

stage(
    name = "stage",
    base_prefix = "{PROJECT_NAME}/{STAGE_NAME}/{PROJECT_BASE_HREF}",
    files = glob(["out/**"]),
    stamp = [
        "NODE_NAME",
    ],
    tags = ["manual"],
)

ecs_deploy(
    name = "deploy",
    images = [
        "//products/docker:container_image_push",
    ],
    tags = [
        "manual",
        "post_release_task",
    ],
)

Also, files.associations are not respected for extension-less files. It sometimes resolves the correct language but it will default back to Python or Javascript 90% of the time. This does not work:

"files.associations": {
  "BUILD": "bazel"
},

I love the feature, but I had to turn it off because files.associations could not correctly enforce the lang.

"workbench.editor.languageDetection": false

@dapullar already fixed for 1.60.1. Thanks for reporting though!

This SCSS detects as CSS : https://github.com/angular/components/issues/7162#issuecomment-493953159

As discussed, here's another example, this time of HTML that VS Code thinks is an INI file.

Curiously, it flashes up HTML in the status-bar section, before changing to Ini, but that might just be because my previous window had already been manually corrected to HTML.

1. Open new untitled editor
2. Type in a T-SQL query such as SELECT * FROM sys.databases

The language auto detection identifies this as a Dockerfile instead of SQL

[anthonyvdotbe]

Oftentimes when I'm writing plain text, VS Code suddenly detects it as one or the other programming language, even though the result doesn't make sense in the detected language.

As an example, I typed the following (I did a replace of [a-z] with s before posting here):

ssss sssssss sss ssss-ssssssss ssss -> sssssss ssssssss? (sss sss ssssssssssss sssss)
sssss ssss ss ssssssss, ssss ssss & sssss ssss sss ss ssss: ssssssssssss ssssssss ss ss?

which was detected as JavaScript by VS Code, even though that results in 22 JavaScript syntax errors.

Edit: another plaintext example being detected as Ruby:

zzzzz zzzzzzz zzzzz zzzzz -> zzz zzzzzz zzzz zzzzzzzzz zzz, zzzz zzzzzzzz
zzzzzzz zzzzzzz, zzzz zzzzzzzzz (zzz. 2 zzzzzz), zzzzzz zzzzz zz zzzz zzz zz zzzzzzzzzz, zzzzzz zzz + zzzzzzz & zzzz zzzzzzzzzzz zzzzzz

zzz zzzzzzzzzzzzzzzz zzzzzzzzz? zzzzz zz zzzzz & zzz zz zzzzz zzz zzz zzzzzzz

#zzz zzzzz zzzzzzzzzzz zzzzzzzz + #zzz zzzzzzz zzzzzzzzzzz zzz- zz zzzzzzzzz zz zzzzzzz zz zzzzzz? zzzzz zzzz zz 'z zzzzz zzz
zzzzzzzz zzz zzzzzz. zzzz, zzz 'z zzzzzzzz zzzz zzz zzzz

zzz zzz & zzz: zzzz zzzz zzzzzzz zz zzzz, zzzz zzzzzz zzzz zzzzzzzzzzzzzz zzzz zzzz: zzzz zzzz zzzzzz zzzzzz + 'z zz zzzz zzz zzzz zzzz
zzzzzzzzzzzz zzzzzzzzz zzzz zzzzz? zzzzzzzz + zzzzzzzzzzz zzzzz zzzzzzzzz
3 zzzzzzzz zzzzzzz :)

zzzz zzzz zzzzzz: zzzzzzzzz zzzz zzzz zzzzz? zzzzzzzzzzz? zzzzz zzz 'z zzzz zzz zzzzz zzzzz?

zzz/zzzz zzzzzzz: zzzzzzzzzzzzzzzzzzz zzz zz zzz zzzzzz zzz? zzzz zz zzzz zzz z'z zzzz'z zzzzz, zz zzzzz 'z zzzzzz zzzz zz zz zzz zz zzzzzz zzz zzzzzz?

ренессанс страхование обращайтесь в автосалон is treated as INI, reported in https://github.com/microsoft/vscode/issues/150873

[katai5plate]

JS code containing Japanese comments is often recognized as an INI file.

// ゲームパラメータオブジェクト
const gameParameters = {
  ui: {
    alwaysVisible: {
      /** ストレスゲージ */
      stressGauge: 0,
    },
    /** 満腹感％ */
    satiety: 0,
    /** 鎮痛剤の血中濃度％ */
    analgesicBloodLevel: 0,
    /** プレイヤー会話成功率％ */
    playerConversationSuccessRate: 0,
  },
};
