how to change the powershell version that quarto uses for post-render shell command?

[kompre]

Description

I've just found out that quarto uses for post-render shell command a different version of powershell that I use as main.

In any terminal window, the command $PSVersionTable.PSVersion return 7.4.1 (that's what I'm currently using), while the same command executed by quarto as post-render instruction

post-render:
  - powershell $PSVersionTable.PSVersion

will return 5.1

This has created me much confusion because I couldn't understand why my script was failing: it was failing because I was triyng to use stuff not yet supported.

How can I tell quarto which powershell version to use?

That's controlled by your PATH I believe.

You should also be able to provide full path to binary in post render.

I am not on Windows and do not have PowerShell installed. Even-though I would have it, 5.1 is the version used internally by Windows.

In any terminal window, the command $PSVersionTable.PSVersion return 7.4.1 (that's what I'm currently using)

• powershell is the CLI command for powershell 5 version
• pwsh is the CLI command for powershell 7+

See https://learn.microsoft.com/en-us/powershell/scripting/whats-new/differences-from-windows-powershell?view=powershell-7.4#renamed-powershellexe-to-pwshexe

So here you are calling explicitly powershell 5 which is what you get.

Quarto is just calling what ever command you pass using Deno.Run - it won't do anything else about shell configuration or detection.

this I was missing.

I fixed changing powershell to pwsh -Command. What a headache...

By doing

post-render:
  - powershell $PSVersionTable.PSVersion

you asked quarto to run a command for you. The information about Deno.run being used does not change anything.

For this to work

• Command used must be in PATH
• Right command need to be used - Quarto won't call a terminal by default for the user.

Just wanted to clarify.

Gald it works for you now !
