function ConvertTo-WtwRemotePath { <# .SYNOPSIS Normalise a remote filesystem path to its URI path form. .DESCRIPTION Windows paths need real work: `C:\Users\sno\repo` becomes `/c:/Users/sno/repo` — backslashes flipped, drive letter lower-cased, and a leading slash added. Getting any of those three wrong produces a URI VS Code accepts and then silently opens as an empty window, which is why this is its own function with its own tests rather than an inline replace. POSIX paths pass through unchanged apart from backslash normalisation. .PARAMETER Path Absolute path as it exists on the remote machine. .PARAMETER Platform 'windows' | 'linux' | 'macos'. #> [CmdletBinding()] param( [Parameter(Mandatory)] [string] $Path, [string] $Platform = 'linux' ) $normalized = $Path -replace '\\', '/' if ($Platform -ieq 'windows') { # UNC (\\server\share) survives as //server/share — already URI-shaped. if ($normalized -match '^//') { return $normalized } if ($normalized -match '^([A-Za-z]):(/.*)?$') { $drive = $Matches[1].ToLowerInvariant() $rest = if ($Matches.Count -gt 2 -and $Matches[2]) { $Matches[2] } else { '/' } return "/${drive}:$rest" } } if (-not $normalized.StartsWith('/')) { $normalized = "/$normalized" } return $normalized } function ConvertTo-WtwRemoteUri { <# .SYNOPSIS Build a `vscode-remote://ssh-remote+<host>/<path>` URI. .DESCRIPTION Percent-escapes each path segment so worktrees with spaces in their name survive. The Windows drive segment (`c:`) is left alone — escaping its colon to %3A yields a URI VS Code cannot map back to a drive. .PARAMETER Path Absolute path on the remote machine. .PARAMETER HostName SSH host name as the ssh client resolves it (the authority suffix). .PARAMETER Platform 'windows' | 'linux' | 'macos'. #> [CmdletBinding()] param( [Parameter(Mandatory)] [string] $Path, [Parameter(Mandatory)] [string] $HostName, [string] $Platform = 'linux' ) $uriPath = ConvertTo-WtwRemotePath -Path $Path -Platform $Platform $escaped = @($uriPath -split '/' | ForEach-Object { if ([string]::IsNullOrEmpty($_)) { $_ } elseif ($_ -match '^[A-Za-z]:$') { $_ } else { [System.Uri]::EscapeDataString($_) } }) -join '/' return "vscode-remote://ssh-remote+$HostName$escaped" } |
