PowerShell: Wrap example does not work #747

Have you seen this: https://mikefarah.gitbook.io/yq/usage/tips-and-tricks#quotes-in-windows-powershell ? |
As I said: yes. |
|
Oh right sorry - no idea then, I got that advice from here https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_quoting_rules?view=powershell-7.1 for what it's worth - perhaps there's doc for whatever version of powershell you are using.. |
|
The work around is to quote in the following way. .\yq.exe e '{\"wrap\": .}' sample.yamlYou can see that this is strictly a Powershell issue by the following example. echoargs e '{\"wrap\": .}' sample.yaml
|

Here is a Param(
[string]$command,
[string]$yamlFile
)
$escCommand = $command -replace '"','\"' -replace ' ',''
$evalArgs = @("eval", $escCommand, $yamlFile)
Write-Output ".\yq.exe" $evalArgs
Start-Process ".\yq.exe" -ArgumentList $evalArgs -Wait -NoNewWindow -PassThruI am not sure about the removing whitespace bit. But, without it |

Thanks for the pointer on Here's the one thing that confuses me, though: At least in PowerShell 6 (7 doesn't work under remote sessions), the "Arg..." output of PS C:\Users\***> yq -M '{""wrap"": .}' sample.yml
Error: parsing expression: Lexer error: could not match text starting at 1:2 failing at 1:7.
unmatched text: "\"wrap:"
PS C:\Users\***> echoargs e '{""wrap"": .}' sample.yml
Arg 0 is <e>
Arg 1 is <{"wrap": .}>
Arg 2 is <sample.yml>
Command line:
"C:\ProgramData\chocolatey\lib\echoargs\tools\EchoArgs.exe" e "{""wrap"": .}" sample.yml
PS C:\Users\***> yq -M e '{\"wrap\": .}' sample.yml
wrap:
name: Mike
PS C:\Users\***> echoargs e '{\"wrap\": .}' sample.yml
Arg 0 is <e>
Arg 1 is <{"wrap": .}>
Arg 2 is <sample.yml>
Command line:
"C:\ProgramData\chocolatey\lib\echoargs\tools\EchoArgs.exe" e "{\"wrap\": .}" sample.ymlIn fact, another working form — as I just discovered — is this: PS C:\Users\***> yq -M e "{\""wrap\"": .}" sample.yml
wrap:
name: MikeIt doesn't work without the backslashes, and interestingly, PS C:\Users\***> echoargs e "{""wrap"": .}" sample.yml
Arg 0 is <e>
Arg 1 is <{wrap: .}>
Arg 2 is <sample.yml>
Command line:
"C:\ProgramData\chocolatey\lib\echoargs\tools\EchoArgs.exe" e "{"wrap": .}" sample.yml
PS C:\Users\***> echoargs e "{\""wrap\"": .}" sample.yml
Arg 0 is <e>
Arg 1 is <{"wrap": .}>
Arg 2 is <sample.yml>
Command line:
"C:\ProgramData\chocolatey\lib\echoargs\tools\EchoArgs.exe" e "{\"wrap\": .}" sample.yml(Notice how, without the backslashes, |

Powershell 7.4 breaks the behavior of "", a "seems to work just fine now |
|
If you want the old behavior you can use |
|
But yq does some really weird stuff when using prints So yq gets the correct parameters but for some reason thinks |
|
I believe yq is getting the literal string |
Describe the bug
I tried running the sample from https://mikefarah.gitbook.io/yq/v/v4.x/operators/create-collect-into-object#wrap-prefix-existing-object in PowerShell but I can't seem to get it to work.
Version of yq: 4.6.1
Operating system: windows
Installed via: binary release
Input Yaml
Concise yaml document(s) (as simple as possible to show the bug, please keep it to 10 lines or less)
sample.yml:
Command
The command you ran:
Actual behavior
Expected behavior
Additional context
I tried both the original code snippet with single ", but then found out that I apparently have to double the quotes in PowerShell, but that didn't not help either :(.
The text was updated successfully, but these errors were encountered:
