Command History Not Shown In PowerShell 7

[rescenic]

Prerequisites

• I have read and understand the CONTRIBUTING guide
• I looked for duplicate issues before submitting this one

Description

PowerShell 5 can show the last command I typed. But PowerShell 7 can't do that.

Environment

• Oh my Posh version: 3.51
• Theme: jandedobbeleer (Default Theme)
• Operating System: Windows 10 Insiders 2004 Build 20270.1
• Shell: pwsh 5 & 7
• Terminal: native windows

Steps to Reproduce

1. Install using Scoop:

mkdir C:\tools
Invoke-Webrequest https://github.com/JanDeDobbeleer/oh-my-posh3/releases/latest/download/posh-windows-amd64.exe -OutFile C:\tools\oh-my-posh.exe

2. Edit both $PROFILE in respected powershell version folder:
   PowerShell 5: C:\Users\User\Documents\WindowsPowerShell
   PowerShell 7: C:\Users\User\Documents\PowerShell

[ScriptBlock]$Prompt = {
    $lastCommandSuccess = $?
    $realLASTEXITCODE = $global:LASTEXITCODE
    $errorCode = 0
    if ($lastCommandSuccess -eq $false) {
        #native app exit code
        if ($realLASTEXITCODE -ne 0) {
            $errorCode = $realLASTEXITCODE
        }
        else {
            $errorCode = 1
        }
    }
    $startInfo = New-Object System.Diagnostics.ProcessStartInfo
    $startInfo.FileName = "C:\tools\oh-my-posh.exe"
    $cleanPWD = $PWD.ProviderPath.TrimEnd("\")
    $startInfo.Arguments = "-config=""C:\tools\poshthemes\jandedobbeleer.json"" -error=$errorCode -pwd=""$cleanPWD"""
    $startInfo.Environment["TERM"] = "xterm-256color"
    $startInfo.CreateNoWindow = $true
    $startInfo.StandardOutputEncoding = [System.Text.Encoding]::UTF8
    $startInfo.RedirectStandardOutput = $true
    $startInfo.UseShellExecute = $false
    if ($PWD.Provider.Name -eq 'FileSystem') {
      $startInfo.WorkingDirectory = $PWD.ProviderPath
    }
    $process = New-Object System.Diagnostics.Process
    $process.StartInfo = $startInfo
    $process.Start() | Out-Null
    $standardOut = $process.StandardOutput.ReadToEnd()
    $process.WaitForExit()
    $standardOut
    $global:LASTEXITCODE = $realLASTEXITCODE
    #remove temp variables
    Remove-Variable realLASTEXITCODE -Confirm:$false
    Remove-Variable lastCommandSuccess -Confirm:$false
}
Set-Item -Path Function:prompt -Value $Prompt -Force

3. Reload profile / reenter powershell.

Expected behavior: It can show autosuggestions (command suggestion based on command history that I typed). oh-my-posh 2 can show that. But it broke, so I deleted everything about oh-my-posh2.

Actual behavior: PowerShell 7 can't show command suggestions.

I tried to reinstall oh-my-posh3 based on: https://ohmyposh.dev/docs/installation#4-replace-your-existing-prompt, it didn't work at all

[lnu]

Are you talking about command history or autocompletion of commands?
I tried here with the latest version and when I type "$PS" and hit tab, the autocompletion takes place:

And for the profile, I use this:

import-module oh-my-posh
import-module posh-git
Import-Module psini
Set-PoshPrompt jandedobbeleer

it's easier than copy pasting the entier powershell block. It's useful if you want to mess around with it but since everything is in the powershell module, using it is easier.

@lnu , Thanks for your reply. What I mean is this:

The suggestion appears after I type 1 word, then I can hit tab, it will autocomplete.

[lnu]

as you said, works fine with PSReadLine 2.1(Set-PSReadLineOption -PredictionSource History)

[JanDeDobbeleer]

@rescenic command completion has nothing to do with oh-my-posh (regardless of V2 or V3) as it's a feature enabled by PSReadline. Most likely that one's not set up correctly for your PS7.1 shell, there's more information to be found on that here.

Oh my Posh overwrites the prompt function to display a different styled prompt, and does not touch anything outside of that context (in line with the UNIX philosophy).

[rescenic]

@JanDeDobbeleer Thank you for the hint. I tried PSReadline version 2.1.0, and it works now. But version 2.2.0-beta didn't work for PowerShell 7.1.

I have the same theme and I want to know how to remove "pwsh" and "no config"?

This is the $profile

[omarabdelaz1z]

I followed this guide My Ultimate PowerShell prompt with Oh My Posh and the Windows Terminal by Scott Hanselman.

[JanDeDobbeleer]

@omarabdelaz1z OK, so there are two things. Firstly, the NO CONFIG is because probably the ~\tonybaloney.omp.json file is not there, so you might want to double-check as you see the default config, not the one that's loaded. Secondly, to adjust the segments (pwsh indication is the shell segment), you need to tweak the config (but in this case, first check if you have ~\tonybaloney.omp.json).

[omarabdelaz1z]

I have added the theme.omp.json in the current-user directory and it works like a charm.
Thank you man, Great theme btw.

[JanDeDobbeleer]

@omarabdelaz1z my pleasure, if you want to get rid of that space, have a look at this FAQ item.

You are king!
