file_browser.py DOX

Purpose

• Own the file_browser.py helper module.
• This module builds safe file-browser views over allowed filesystem roots.
• Keep this file-level DOX profile synchronized with file_browser.py because this directory is intentionally flat.

Ownership

• file_browser.py owns the runtime implementation.
• file_browser.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Classes:
• FileBrowser (no explicit base class)
  • save_file_b64(self, current_path: str, filename: str, base64_content: str)
  • save_files(self, files: List, current_path: str=...) -> Tuple[List[str], List[str]]
  • delete_file(self, file_path: str) -> bool
  • rename_item(self, file_path: str, new_name: str) -> bool
  • create_folder(self, parent_path: str, folder_name: str) -> bool
  • save_text_file(self, file_path: str, content: str) -> bool
  • get_files(self, current_path: str=...) -> Dict
  • get_full_path(self, file_path: str, allow_dir: bool=...) -> str

Runtime Contracts

• Helper modules own reusable framework APIs and must preserve public callers unless all callers, tests, and docs are updated together.
• Update this file whenever public functions, classes, persistence behavior, path/security assumptions, side effects, or cross-module contracts change.
• Observed side-effect areas: filesystem reads, filesystem writes, filesystem deletion, subprocess/runtime control, settings/state persistence.
• Imported dependency areas include: base64, datetime, helpers, helpers.localization, helpers.print_style, helpers.security, os, pathlib, shutil, subprocess, typing.

Key Concepts

• Important called helpers/classes observed in the source: Path, files.get_abs_path, self._get_file_extension, file.seek, file.tell, resolve, os.makedirs, os.path.exists, full_path.with_name, new_path.exists, os.rename, target_dir.exists, filename.rsplit.lower, subprocess.run, result.stdout.strip.split, self._get_files_via_ls, files.exists, ValueError, str.startswith, file.write.
• Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Work Guidance

• Preserve public helper APIs used by core code and plugins unless every caller is updated.
• Keep path, auth, secret, persistence, network, and subprocess behavior explicit and bounded.
• Prefer adding cohesive helper functions here only when behavior is reused across modules.

Verification

• Run targeted tests for changed helper behavior; run security regressions for auth, filesystem, WebSocket, tunnel, upload, or secret-handling helpers.
• Related tests observed by source search:
  • tests/test_download_toast_regressions.py
  • tests/test_office_document_store.py
