Username with one or more spaces causes an error

[2gn]

Steps to reproduce

1. (optional) change your username to include one or more spaces
2. If you have already br installed, run br --install
3. run broot --install
4. the command above creates $HOME\Documents\WindowsPowershell\Profile.ps1 with the following contents (when username is "User Name")

   . C:\Users\User\ Name\AppData\Roaming\dystroy\broot\config\launcher\powershell\br.ps1

Possible solution

Use $HOME environment variable instead so windows will automatically expand it on execution appropriately.

Using $HOME directly in the command isn't something you can do when creating a file in a program, you have to expand the path.

But an appropriate escaping is probably missing.

This also happens when trying to use inshellisense, by the way.

PS …\User Name\Development> inshellisense
'C:\Users\User' is not recognized as an internal or external command,
operable program or batch file.

It seems there are two errors that should be resolved.

1. issue above
2. File not found error

PS …\Development\broot> br
File not found: "C:\\Users\\User Name\\AppData\\Local\\Temp\\tmpBA8F.tmp"

https://github.com/Canop/broot/blob/8f50c72f58fbfd48d686aeb6ed1b1e79b5069204/src/shell_install/powershell.rs#L27-L33

In line 29 of powershell.rs, (New-TemporaryFile).FullName is expanded inside string expression. That's causing the error.

Plus, I noticed that broot --install patches the script only for natively installed powershell, and doesn't work with powershell core, which is newer. I'll make a different PR/issue for this.

Here's a hacky solution I've discovered (with help of GPT)

1. Manually replace the path to br.ps1 created by br --install with . "$HOME\AppData\Roaming\dystroy\broot\config\launcher\powershell\br.ps1" inside $PROFILE
2. replace the content of the file $HOME\AppData\Roaming\dystroy\broot\config\launcher\powershell\br.ps1 with following

https://github.com/Canop/broot/issues/460#issuecomment-1303005689

Function br { $args = $args -join ' ' $cmd_file = New-TemporaryFile $cmd_file_path = $cmd_file.FullName $quoted_cmd_file = ""$cmd_file_path""

$process = Start-Process -FilePath 'broot.exe' -ArgumentList "--outcmd $quoted_cmd_file $args" -NoNewWindow -PassThru -WorkingDirectory $PWD

Wait-Process -InputObject $process #Faster than Start-Process -Wait If ($process.ExitCode -eq 0) { $cmd = Get-Content $cmd_file_path Remove-Item -Path $cmd_file_path If ($cmd -ne $null) { Invoke-Expression -Command $cmd } } Else { Remove-Item -Path $cmd_file_path Write-Host "`n" # Newline to tidy up broot unexpected termination Write-Error "broot.exe exited with error code $($process.ExitCode)" } }

I know the code is pretty dirty and hacky but it now works fine. Just a workaround for people who are still struggling with this problem.

Instead of manually replacing those files, can a clean enough script be proposed in a PR ?

I'm working on it but since I'm not a very good programmer, it may take some time.

Nobody's born a very good programmer. Make your PR and we'll try to have some people with powershell knowledge review it and provide advice or fixes.

Try this and tell me how it goes!

Function br {
  $args = $args -join ' '
  $cmd_file = New-TemporaryFile
  $out_file = New-TemporaryFile

  $process = Start-Process -FilePath 'broot.exe' `
                           -ArgumentList "--outcmd `"$cmd_file`" $args" `
                           -NoNewWindow -PassThru -WorkingDirectory $PWD `
                           -RedirectStandardOutput $out_file

  Wait-Process -InputObject $process # Faster than Start-Process -Wait
  Get-Content $out_file # print broot's stdout to shell stdout
  If ($process.ExitCode -eq 0) {
    $cmd = Get-Content $cmd_file
    Remove-Item $cmd_file, $out_file
    If ($cmd -ne $null) { Invoke-Expression -Command $cmd }
  } Else {
    Remove-Item $cmd_file, $out_file
    Write-Host "`n" # Newline to tidy up broot unexpected termination
    Write-Error "broot.exe exited with error code $($process.ExitCode)"
  }
}
