pure-pwsh

PowerShell implementation of the pure prompt.

Loads git status information asynchronously so that the prompt doesn't block and is able to update the prompt in response to file system changes without any user interation.

Dependencies

• Terminal with ANSI colour support
• PowerShell 7.0+
• Git 2.0+ on your path

Installation

Install from the gallery or clone this repository

Install-Module pure-pwsh

and import it in your profile. If you use this with posh-git (e.g. for its excellent Git completion) then you'll probably want to import pure-pwsh first so that posh-git doesn't spend time configuring its own prompt.

# ~/Documents/PowerShell/Microsoft.PowerShell_profile.ps1

Import-Module pure-pwsh
Import-Module posh-git

Compatibility

pure-pwsh should work anywhere PowerShell 7 does, including Windows, Mac, and Linux. Due to a longstanding bug in PSReadLine, async updates may not be scheduled on Mac and Linux until you interact with the console in some way.

Not currently included

• No vi mode indicator
• No git stash indicator
• No git action indicator (rebase, cherry pick, etc.)
• No python virtual env indicator

Consider raising an issue if you want any of the above, or use one of the recipes below.

Recipes

Shorten path segments

Abbreviate each segment of the current path except for the leaf node.

$pure.PwdFormatter = {
  (
    ((Split-Path $pwd).Replace($HOME, '~').Split($pwd.Provider.ItemSeparator) |% {$_[0]}) +
    (Split-Path -Leaf $pwd)
  ) -join '/'
}

Truncate branch name

Truncate the branch name to a maximum of 12 characters.

$pure.BranchFormatter = {
  param ($n)
  $n.Length -lt 12 ? $n : ($n[0..11] -join '') + '…'
}

Show git stash indicator

$pure.PrePrompt = {
  param ($user, $cwd, $git, $slow)
  "`n$user{0}$cwd $git{1}$slow `n" -f($user ? ' ' : ''), ((git stash list) ? ' ≡ ' : '')
}

Show Python virtual env

$pure.PrePrompt = {
    param ($user, $cwd, $git, $slow)
    "`n$user{1}{0}$cwd $git $slow `n" -f
    ($user ? ' ' : ''),
    (($ve = $env:virtual_env) ? "$($pure._branchcolor)($(Split-Path -Leaf $ve)) " : "" )
}

One line prompt

$pure.UserColor = '38;5;242;4'

$pure.PrePrompt = {
  param ($user, $cwd, $git, $slow)
  $seperator = $pure._branchcolor +  " ❯ "
  "`n$user{0}$cwd{1}$git$slow " -f
    ($user ? $seperator : ''),
    ($git ? $seperator : '')
}

Use a different colour for user and hostname parts

$pure.UserFormatter = { param ($ssh, $user, $hostname) $ssh ? "$user`e[32m@$hostname" : '' }
