Configuration

Oh My Posh renders your prompt based on the definition of blocks (like Lego) which contain one or more segments. A really simple configuration could look like this.

{
"final_space": true,
"blocks": [
{
"type": "prompt",
"alignment": "left",
"segments": [
{
"type": "path",
"style": "powerline",
"powerline_symbol": "\uE0B0",
"foreground": "#ffffff",
"background": "#61AFEF",
"properties": {
"prefix": " \uE5FF ",
"style": "folder"
}
}
]
}
]
}

With this configuration, a single powerline segment is rendered that shows the name of the folder you're currently in. To set this configuration in combination with a Oh My Posh executable, use the --config flag to set a path to a JSON file containing the above code. The --shell universal flag is used to print the prompt without escape characters to see the prompt as it would be shown inside a prompt function for your shell.

caution

The command below will not persist the configuration for your shell but print the prompt in your terminal. If you want to use your own configuration permanently, adjust the prompt configuration to use your custom theme.

oh-my-posh --config sample.json --shell universal

If all goes according to plan, you should see the prompt being printed out on the line below. In case you see a lot of boxes with question marks, set up your terminal to use a supported font before continuing.

General Settings#

  • final_space: boolean - when true adds a space at the end of the prompt
  • osc99: boolean - when true adds support for OSC9;9; (notify terminal of current working directory)
  • console_title: boolean - when true sets the current location as the console title
  • console_title_style: string - the title to set in the console - defaults to folder
  • console_title_template: string - the template to use when "console_title_style" = "template"
  • terminal_background: string color - terminal background color, set to your terminal's background color when you notice black elements in Windows Terminal or the Visual Studio Code integrated terminal

"I Like The Way You Speak Words" - Gary Goodspeed

Console Title Style#

  • folder: show the current folder name
  • path: show the current path
  • template: show a custom template

Console Title Template#

You can create a more custom console title with the use of "console_title_style" = "template". When this is set, a console_title_template is also expected, otherwise, the title will remain empty. Under the hood, this uses go's text/template feature extended with sprig and offers a few standard properties to work with.

  • .Root: boolean - is the current user root/admin or not
  • .Path: string - the current working directory
  • .Folder: string - the current working folder
  • .Shell: string - the current shell name
  • .User: string - the current user name
  • .Host: string - the host name
  • .Env.VarName: string - Any environment variable where VarName is the environment variable name

A boolean can be used for conditional display purposes, a string can be displayed.

The following examples illustrate possible contents for console_title_template, provided the current working directory is /usr/home/omp and the shell is zsh.

{
"console_title_template": "{{.Folder}}{{if .Root}} :: root{{end}} :: {{.Shell}}",
// outputs:
// when root == false: omp :: zsh
// when root == true: omp :: root :: zsh
"console_title_template": "{{.Folder}}", // outputs: omp
"console_title_template": "{{.Shell}} in {{.Path}}", // outputs: zsh in /usr/home/omp
"console_title_template": "{{.User}}@{{.Host}} {{.Shell}} in {{.Path}}", // outputs: MyUser@MyMachine zsh in /usr/home/omp
"console_title_template": "{{.Env.USERDOMAIN}} {{.Shell}} in {{.Path}}", // outputs: MyCompany zsh in /usr/home/omp
}

Block#

Let's take a closer look at what defines a block.

  • type: prompt | rprompt
  • newline: boolean
  • alignment: left | right
  • vertical_offset: int
  • horizontal_offset: int
  • segments: array of one or more segments

Type#

Tells the engine what to do with the block. There are three options:

  • prompt renders one or more segments
  • rprompt renders one or more segments aligned to the right of the cursor. Only one rprompt block is permitted. Supported on ZSH, Bash and Powershell.

Newline#

Start the block on a new line. Defaults to false.

Alignment#

Tell the engine if the block should be left or right-aligned.

Vertical offset#

Move the block up or down x lines. For example, vertical_offset: 1 moves the prompt down one line, vertical_offset: -1 moves it up one line.

Horizontal offset#

Moves the segment to the left or the right to have it exactly where you want it to be. Works like vertical_offset but on a horizontal level where a negative number moves the block left and a positive number right.

Segments#

Array of one or more segments.

Segment#

A segment is a part of the prompt with a certain context. There are different types available out-of-the-box, if you're looking for what's included, feel free to skip this part and browse through the segments. Keep reading to understand how to configure a segment.

  • type: string any of the included segments
  • style: powerline | plain | diamond
  • powerline_symbol: string
  • invert_powerline: boolean
  • leading_diamond: string
  • trailing_diamond: string
  • foreground: string color
  • foreground_templates: array of string values
  • background: string color
  • background_templates: array of string values
  • properties: array of Property: string

Type#

Takes the string value referencing which segment logic it needs to run (see segments for possible values).

Style#

Oh Hi! You made it to a really interesting part, great! Style defines how a prompt is rendered. Looking at the most prompt themes out there, we identified 3 types. All of these require a different configuration and depending on the look you want to achieve you might need to understand/use them all.

Powerline#

What started it all for us. Makes use of a single symbol (powerline_symbol) to separate the segments. It takes the background color of the previous segment (or transparent if none) and the foreground of the current one (or transparent if we're at the last segment). Expects segments to have a colored background, else there little use for this one.

Plain#

Simple. Colored text on a transparent background. Make sure to set foreground for maximum enjoyment. Segments will be separated by empty spaces unless you specify '' for the prefix and postfix settings for the segment.

Diamond#

While Powerline works great with as single symbol, sometimes you want a segment to have a different start and end symbol. Just like a diamond: < my segment text >. The difference between this and plain is that the diamond symbols take the segment background as their foreground color.

Powerline symbol#

Text character to use when "style": "powerline".

Invert Powerline#

If true this swaps the foreground and background colors. Can be useful when the character you want does not exist in the perfectly mirrored variant for example.

Leading diamond#

Text character to use at the start of the segment. Will take the background color of the segment as its foreground color.

Trailing diamond#

Text character to use at the end of the segment. Will take the background color of the segment as its foreground color.

Foreground#

Color to use as the segment text foreground color. Also supports transparency using the transparent keyword.

Foreground Templates#

Array if string templates to define the foreground color for the given Segment based on the Segment's Template Properties. Under the hood this uses go's text/template feature extended with sprig and offers a few standard properties to work with. For supported Segments, look for the Template Properties section in the documentation.

The following sample is based on the AWS Segment.

{
"type": "aws",
"style": "powerline",
"powerline_symbol": "๎‚ฐ",
"foreground": "#ffffff",
"background": "#111111",
"foreground_templates": [
"{{if contains \"default\" .Profile}}#FFA400{{end}}",
"{{if contains \"jan\" .Profile}}#f1184c{{end}}"
],
"properties": {
"prefix": " \uE7AD "
}
}

The logic is as follows: when background_templates contains an array, we will check every template line until there's one that returns a non-empty string. So, when the contents of .Profile contain the word default, the first template returns #FFA400 and that's the color that will be used. If it contains jan, it returns #f1184c. When none of the templates returns a value, the foreground value #ffffff is used.

Background#

Color to use as the segment text background color. Also supports transparency using the transparent keyword.

Background Templates#

Same as Foreground Templates but for the background color.

Properties#

An array of Properties with a value. This is used inside of the segment logic to tweak what the output of the segment will be. Segments have the ability to define their own Properties, but there are some general ones being used by the engine which allow you to customize the output even more.

General-purpose properties#

You can use these on any segment, the engine is responsible for adding them correctly.

  • prefix: string
  • postfix: string
  • include_folders: []string
  • exclude_folders: []string
Prefix#

The string content will be put in front of the segment's output text. Useful for symbols, text or other customizations. If this is not set, it will be an empty space in plain mode. If you want to remove the space before the segment, specify this as ''.

Postfix#

The string content will be put after the segment's output text. Useful for symbols, text or other customizations. If this is not set, it will default to an empty space in plain mode. If you want to remove the space after the segment, specify this as ''.

Include / Exclude Folders#

Sometimes you might want to have a segment only rendered in certain folders. If include_folders is specified, the segment will only be rendered when in one of those locations. If exclude_folders is specified, the segment will not be rendered when in one of the excluded locations.

"include_folders": [
"/Users/posh/Projects"
]
"exclude_folders": [
"/Users/posh/Projects"
]

The strings specified in these properties are evaluated as regular expressions. You can use any valid regular expression construct, but the regular expression must match the entire directory name. The following will match /Users/posh/Projects/Foo but not /home/Users/posh/Projects/Foo.

"include_folders": [
"/Users/posh/Projects.*"
]

You can also combine these properties:

"include_folders": [
"/Users/posh/Projects.*"
],
"exclude_folders": [
"/Users/posh/Projects/secret-project.*"
]
Notes#
  • Oh My Posh will accept both / and \ as path separators for a folder and will match regardless of which is used by the current operating system.
  • Because the strings are evaluated as regular expressions, if you want to use a \ in a Windows directory name, you need to specify it as \\\\.
  • The character ~ at the start of a specified folder will match the user's home directory.
  • The comparison is case-insensitive on Windows and macOS, but case-sensitive on other operating systems.

This means that for user Bill, who has a user account Bill on Windows and bill on Linux, ~/Foo might match C:\Users\Bill\Foo or C:\Users\Bill\foo on Windows but only /home/bill/Foo on Linux.

Colors#

Standard colors#

Oh My Posh supports four different color types being:

  • Typical hex colors (for example #CB4B16).

  • The transparent keyword which can be used to create either a transparent foreground override or transparent background color using the segment's foreground property.

  • The inherit keyword which can be used to inherit the previous active segment's foreground and/or background color.

  • 16 ANSI color names.

    These include 8 basic ANSI colors and default:

    black red green yellow blue magenta cyan white default

    as well as 8 extended ANSI colors:

    darkGray lightRed lightGreen lightYellow lightBlue lightMagenta lightCyan lightWhite

Color overrides#

You have the ability to override the foreground and/or background color for text in any property that accepts it. The syntax is custom but should be rather straight-forward: <#ffffff,#000000>this is white with black background</> <#FF479C>but this is pink</>. Anything between the color start <#FF479C> and end </> will be colored accordingly.

For example, if you want prefix to print a colored bracket that isn't the same as the segment's foreground, you can do so like this:

"prefix": "<#CB4B16>โ”[</>",

If you also wanted to change the background color in the previous command, you would do so like this:

"prefix": "<#CB4B16,#FFFFFF>โ”[</>",

To change only the background color, just omit the first color from the above string:

"prefix": "<,#FFFFFF>โ”[</>",

Text decorations#

You can make use of the following syntax to decorate text:

  • <b>bold</b>: renders bold as bold text
  • <u>underline</u>: renders underline as underlined text
  • <i>italic</i>: renders italic as italic text
  • <s>strikethrough</s>: renders strikethrough as strikethrough text

This can be used in templates and icons/text inside your config.

Hyperlinks#

The engine has the ability to render hyperlinks. Your terminal has to support it and the option has to be enabled at the segment level. Hyperlink generation is disabled by default.
