--- id: templates title: Templates sidebar_label: Templates --- import Tabs from "@theme/Tabs"; import TabItem from "@theme/TabItem"; Every segment has a `template` property to tweak the text that is displayed. Under the hood, this uses go's [text/template][go-text-template] feature extended with [sprig][sprig] and offers a few standard properties to work with. ## Global properties These properties can be used anywhere, in any segment. If a segment contains a property with the same name, the segment property value will be used instead. In case you want to use the global property, you can prefix it with `.$` to reference it directly. | Name | Type | Description | | --------------- | --------- | ----------------------------------------------------------------- | | `.Root` | `boolean` | is the current user root/admin or not | | `.PWD` | `string` | the current working directory | | `.Folder` | `string` | the current working folder | | `.Shell` | `string` | the current shell name | | `.ShellVersion` | `string` | the current shell version | | `.SHLVL` | `int` | the current shell level | | `.UserName` | `string` | the current user name | | `.HostName` | `string` | the host name | | `.Code` | `int` | the last exit code | | `.OS` | `string` | the operating system | | `.WSL` | `boolean` | in WSL yes/no | | `.Templates` | `string` | the [templates][templates] result | | `.PromptCount` | `int` | the prompt counter, increments with 1 for every prompt invocation | ## Environment variables | Name | Type | Description | | -------------- | -------- | ------------------------------------------------------------------------- | | `.Env.VarName` | `string` | Any environment variable where `VarName` is the environment variable name | :::tip For the shells below, you can override a function to execute some logic before the prompt is rendered. This can be used to for example populate an environment variable with a specific context. ```powershell function Set-EnvVar { $env:POSH=$(Get-Date) } New-Alias -Name 'Set-PoshContext' -Value 'Set-EnvVar' -Scope Global -Force ``` ```bash function set_poshcontext() { export POSH=$(date) } ``` ```bash function set_poshcontext() { export POSH=$(date) } ``` ```shell function set_poshcontext set --export POSH $(date) end ``` ::: ## Config variables | Name | Type | Description | | -------------- | ----- | -------------------------------------------------------- | | `.Var.VarName` | `any` | Any config variable where `VarName` is the variable name | ### Example ```json { "$schema": "https://raw.githubusercontent.com/JanDeDobbeleer/oh-my-posh/main/themes/schema.json", "version": 2, // highlight-start "var": { "Hello": "hello", "World": "world" }, // highlight-end "blocks": [ { "type": "prompt", "alignment": "left", "segments": [ { "type": "text", "style": "plain", "foreground": "p:white", // highlight-next-line "template": "{{ .Var.Hello }} {{ .Var.World }} " } ] } ] } ``` ## Template logic | Template | Description | | -------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `{{.}}` | Root element. | | `{{.Var}}` | Variable in a struct, where Var is a variable. | | `{{- .Var -}}` | Remove extra white space surrounding the .Var variable and remove the newline. Either side is fine too. | | `{{ $planet := "Earth"}}` | `{{ $planet }}` Store a value in a custom variable to reference later. Note that .$ is used to reference the global/parent context, like in the full example below with $. | | `Hi {{if .Name}} {{.Name}} {{else}} visitor {{end}}` | If-else statement. If will will evaluate whether or not the argument is empty. Using the elseif conditional is also an option. The not negation is available too. | | `{{if and .Arg1 .Arg2}} both complete. {{else}} incomplete. {{end}}` | The and function compares multiple arguments to return the boolean AND (if arg1 then arg2 else arg1). Both arguments are evaluated. The or function compares multiple arguments to return the boolean OR. Similar to if arg1 then arg1 else arg2, so arg2 will never be evaluated if arg1 is false (not empty). | | `{{with .Var}} {{end}}` | With statement, where Var is a variable. It skips the block if the variable is absent. | | `{{range .Array}} {{end}}` | Range statement, where Array is an array, slice, map, or channel. | | `{{ lt 3 4 }}` | This lt comparison function evaluates to true since 3 is less than 4 (other boolean operators: eq, ne, lt, le, gt, ge). | ## Helper functions ### Sprig Oh My Posh has all [sprig][sprig] functions included, meaning you can do operations on strings, paths and a lot of other manipulations straight from your template. Have a look at [their documentation][sprig] for available options and how to use them. ### Custom | Template | Description | | -------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------- | | `{{ url .UpstreamIcon .UpstreamURL }}` | Create a hyperlink to a website to open your default browser (needs terminal [support][terminal-list-hyperlinks]). | | `{{ path .Path .Location }}` | Create a link to a folder to open your file explorer (needs terminal [support][terminal-list-hyperlinks]). | | `{{ secondsRound 3600 }}` | Round seconds to a time indication. In this case the output is `1h`. | | `{{ if glob "*.go" }}OK{{ else }}NOK{{ end }}` | Exposes [filepath.Glob][glob] as a boolean template function. | | `{{ if matchP "*.Repo" .Path }}Repo{{ else }}No Repo{{ end }}` | Exposes [regexp.MatchString][regexpms] as a boolean template function. | | `{{ replaceP "c.t" "cut code cat" "dog" }}` | Exposes [regexp.ReplaceAllString][regexpra] as a string template function. | | {{ .Code | hresult }} | Transform a status code to its HRESULT value for easy troubleshooting. For example `-1978335212` becomes `0x8A150014`. | ## Cross segment template properties To use another segment's template properties in a template, you can make use of `{{ .Segments.Segment }}` in your template where `.Segment` is the name of the segment you want to use with the first letter uppercased. If you want to for example use the [git][git] segment's `.UpstreamGone` property in the [exit][exit] segment, you can do so like this: ```json "template": " {{ if .Segments.Git.UpstreamGone }}\ueb05{{ else if gt .Code 0 }}\uf00d{{ else }}\uf00c{{ end }} " ``` :::caution For this to work, the segment you refer to needs to be in your config. The above example won't work if your config does not contain a git segment as Oh My Posh only populates the properties when it needs to. ::: :::tip If you have two identical segments for a different purpose, you can make use of the `alias` property on the segment to distinct between both. For example: ```json { "type": "command", // highlight-next-line "alias": "Hello", "style": "plain", "foreground": "#ffffff", "properties": { "command": "echo Hello" } }, { "type": "command", // highlight-next-line "alias": "World", "style": "plain", "foreground": "#ffffff", "properties": { "command": "echo World" } }, { "type": "text", "style": "plain", "foreground": "#ffffff", // highlight-next-line "template": "{{ .Segments.Hello.Output }} {{ .Segments.World.Output }}" } ``` ::: If you want to know if a specific segment is active, you can use the `.Segments.Contains` function, for example: ```json "template": "{{ if .Segments.Contains \"Git\" }}\ueb05{{ else if gt .Code 0 }}\uf00d{{ else }}\uf00c{{ end }} " ``` ## Text decoration You can make use of the following syntax to decorate text: | Syntax | Description | | ---------------------- | ------------------------------------- | | `bold` | `bold` as bold text | | `underline` | `underline` as underlined text | | `overline` | `overline` as overlined text | | `italic` | `italic` as italic text | | `strikethrough` | `strikethrough` as strikethrough text | | `dimmed` | `dimmed` as dimmed text | | `blink` | `blink` as blinking (flashing) text | | `reversed` | `reversed` as reversed text | This can be used in templates and icons/text inside your config.
