# Prompt.ps1 - palette-aware oh-my-posh prompt generation. # # Most oh-my-posh themes hardcode their own colors, so swapping the prompt while # keeping a scheme leaves the prompt clashing with everything else. The 'auto' # prompt sidesteps that: it generates a clean oh-my-posh config whose segment # colors are pulled straight from the active scheme, so the prompt always matches. # Build an oh-my-posh config (v2) from a scheme's colors. -Style picks the layout: # classic - path · git · ❯ (plain, no background fills) # minimal - just a colored ❯ that turns red on a non-zero exit # powerline - filled powerline segments (needs a nerd font for the separators) # robby - robbyrussell-style: ❯❯ folder git:(branch) time (no glyphs needed) function New-PoshPaletteOmpConfig { param( [Parameter(Mandatory)] $Colors, [ValidateSet('classic','minimal','powerline','robby','twoline','arrow','lambda','pure')] [string] $Style = 'classic' ) $get = { param($name, $fallback) $v = $Colors.$name if ([string]::IsNullOrWhiteSpace($v)) { $fallback } else { $v } } $bg = & $get 'background' '#1A1B26' $blue = & $get 'blue' '#7AA2F7' $green = & $get 'green' '#9ECE6A' $red = & $get 'red' '#F7768E' $purple = & $get 'purple' '#BB9AF7' $cyan = & $get 'cyan' '#7DCFFF' $yellow = & $get 'yellow' '#E0AF68' $fg = & $get 'foreground' '#C0CAF5' $chg = "{{ if or (.Working.Changed) (.Staging.Changed) }}$red{{ end }}" # Reusable plain segments (scheme-colored). $pathSeg = { param($fg, $tpl) [ordered]@{ type = 'path'; style = 'plain'; foreground = $fg; properties = [ordered]@{ style = 'folder' }; template = $tpl } } $gitSeg = { param($fg, $tpl) [ordered]@{ type = 'git'; style = 'plain'; foreground = $fg; foreground_templates = @($chg); properties = [ordered]@{ fetch_status = $true; branch_icon = '' }; template = $tpl } } $timeSeg = { param($fg) [ordered]@{ type = 'time'; style = 'plain'; foreground = $fg; template = '{{ .CurrentDate | date "15:04" }} ' } } $statSeg = { param($fg, $tpl) [ordered]@{ type = 'status'; style = 'plain'; foreground = $fg; foreground_templates = @("{{ if gt .Code 0 }}$red{{ end }}"); properties = [ordered]@{ always_enabled = $true }; template = $tpl } } $textSeg = { param($fg, $tpl) [ordered]@{ type = 'text'; style = 'plain'; foreground = $fg; template = $tpl } } $line = { param($segs, [bool]$nl = $false) $b = [ordered]@{ type = 'prompt'; alignment = 'left'; segments = @($segs) }; if ($nl) { $b['newline'] = $true }; $b } $blocks = @(switch ($Style) { 'robby' { & $line @( (& $textSeg $cyan '❯❯') (& $pathSeg $blue ' {{ .Path }} ') (& $gitSeg $green 'git:({{ .HEAD }}) ') (& $timeSeg $yellow) ) } 'minimal' { & $line @((& $statSeg $purple '❯ ')) } 'powerline' { & $line @( [ordered]@{ type = 'path'; style = 'powerline'; powerline_symbol = "$([char]0xE0B0)"; foreground = $bg; background = $blue; properties = [ordered]@{ style = 'folder' }; template = ' {{ .Path }} ' } [ordered]@{ type = 'git'; style = 'powerline'; powerline_symbol = "$([char]0xE0B0)"; foreground = $bg; background = $green; background_templates = @("{{ if or (.Working.Changed) (.Staging.Changed) }}$purple{{ end }}"); properties = [ordered]@{ fetch_status = $true }; template = " $([char]0xE0A0) {{ .HEAD }} " } [ordered]@{ type = 'status'; style = 'powerline'; powerline_symbol = "$([char]0xE0B0)"; foreground = $bg; background = $cyan; background_templates = @("{{ if gt .Code 0 }}$red{{ end }}"); properties = [ordered]@{ always_enabled = $true }; template = ' {{ if gt .Code 0 }}✗{{ else }}✓{{ end }} ' } ) } 'twoline' { (& $line @( (& $textSeg $cyan '╭─ ') (& $pathSeg $blue '{{ .Path }} ') (& $gitSeg $green '● {{ .HEAD }} ') (& $timeSeg $yellow) )) (& $line @( (& $textSeg $cyan '╰─') (& $statSeg $purple '❯ ') ) $true) } 'arrow' { & $line @( (& $pathSeg $blue '{{ .Path }} ') (& $textSeg $cyan 'on ') (& $gitSeg $green '● {{ .HEAD }} ') (& $timeSeg $yellow) (& $statSeg $purple '❯ ') ) } 'lambda' { & $line @( (& $textSeg $purple 'λ ') (& $pathSeg $blue '{{ .Path }} ') (& $textSeg $green '→ ') ) } 'pure' { (& $line @((& $pathSeg $blue '{{ .Path }}'))) (& $line @((& $statSeg $purple '❯ ')) $true) } default { # classic & $line @( (& $pathSeg $blue ' {{ .Path }} ') [ordered]@{ type = 'git'; style = 'plain'; foreground = $green; properties = [ordered]@{ fetch_status = $true }; template = '{{ .HEAD }}{{ if or (.Working.Changed) (.Staging.Changed) }}*{{ end }} ' } (& $statSeg $purple '❯ ') ) } }) [ordered]@{ '$schema' = 'https://raw.githubusercontent.com/JanDeDobbeleer/oh-my-posh/main/themes/schema.json' version = 2 final_space = $true blocks = @($blocks) } } # Write a generated config to the PoshPalette-managed prompt dir; return its path. function Save-PoshPalettePrompt { param([Parameter(Mandatory)] $Config, [string] $Name = 'auto') $dir = Join-Path $HOME '.poshpalette/prompts' if (-not (Test-Path $dir)) { New-Item -ItemType Directory -Path $dir -Force | Out-Null } $path = Join-Path $dir "$Name.omp.json" Set-Content -Path $path -Value ($Config | ConvertTo-Json -Depth 32) -Encoding utf8 $path } |
