WSL-aware editor opening

On Windows, installed Visual Studio Code editions gain one editor choice per detected Windows Subsystem for Linux distribution, for example Visual Studio Code — WSL: Ubuntu. The choices work as global defaults and as repository-specific editor overrides anywhere Desktop Material already offers Open in editor.

Behavior and configuration

Desktop Material discovers up to 32 unique distributions through wsl.exe --list --quiet. When a WSL editor is selected, a normal Windows path is translated with that exact distribution's wslpath; a \\wsl.localhost\Distro\... or \\wsl$\Distro\... path is mapped directly. Visual Studio Code then receives its remote target and Linux path as separate arguments. The selection persists through the existing editor setting or per-repository override.

Failure modes and recovery

Unavailable WSL installations simply add no choices. Discovery and translation have five-second and 64 KiB bounds. A stopped distribution, missing path translator, invalid result, or UNC share belonging to another distribution produces an editor error with recovery guidance; choose the matching entry or start the distribution and retry.

Security considerations

No shell parses a repository path or distribution name. The application starts wsl.exe and the editor with positional argument arrays, rejects control characters and oversized values, bounds captured output, and requires cross-distribution UNC paths to be selected explicitly.

Verification

Unit coverage exercises UTF-8 and UTF-16LE discovery output, name deduplication, UNC mapping and mismatch rejection, exact wslpath arguments, VS Code remote arguments, invalid names, and malformed translated paths.
