extendnba

Additional indicators for non-basic ASCII characters in your files.

"Basic ASCII" here means printable ASCII characters (0x20-0x7E) plus the common whitespace control characters tab, line feed, and carriage return. Anything else — extended/control characters, accented letters, emoji, smart quotes, non-breaking spaces, other Unicode symbols, etc. — is treated as "non-basic ASCII".

Features

• Gutter indicator: any line containing a non-basic ASCII character gets a marker in the editor gutter, making it easy to spot at a glance.
• Problems panel entry: whenever a file contains one or more non-basic ASCII characters, a warning diagnostic titled Non-basic ASCII characters present is added to the Problems panel, pointing at the first offending character.
• Only real files (on-disk or unsaved "untitled" editors) are analyzed. Virtual/temporary documents created by other tooling — such as the git diff view VS Code shows for version-controlled files — are ignored automatically, so you won't see duplicate or bogus problems like batch_submit.py.git.

Both indicators update live as you type, switch editors, or open/close files.

Extension Settings

This extension contributes the following setting:

• extendnba.ignorePatterns: An array of glob patterns for files/paths that should be excluded from the gutter indicator and Problems panel diagnostic. Patterns are matched against both the workspace-relative path and the absolute file path. Defaults to ["**/.git/**"].

  "extendnba.ignorePatterns": [
    "**/.git/**",
    "**/dist/**",
    "**/*.min.js"
  ]

Requirements

No additional requirements or configuration — the extension works out of the box on all open text documents.

Known Issues

None currently known.

• Added the extendnba.ignorePatterns setting to let users exclude files or folders by glob pattern.

0.0.2

Added gutter indicators and Problems panel diagnostics for non-basic ASCII characters.

Enjoy!
