General

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. The default format is json, but we also support toml and yaml. There's a schema available which is kept up-to-date and helps with autocomplete and validation of the configuration.

info

There are a few themes available which are basically predefined configs. You can use these as they are, or as a starting point to create your own configuration.

json

{
  "$schema": "https://raw.githubusercontent.com/JanDeDobbeleer/oh-my-posh/main/themes/schema.json",
  "final_space": true,
  "version": 2,
  "blocks": [
    {
      "type": "prompt",
      "alignment": "left",
      "segments": [
        {
          "type": "path",
          "style": "powerline",
          "powerline_symbol": "\uE0B0",
          "foreground": "#ffffff",
          "background": "#61AFEF",
          "properties": {
            "style": "folder"
          }
        }
      ]
    }
  ]
}

yaml

# yaml-language-server: $schema=https://raw.githubusercontent.com/JanDeDobbeleer/oh-my-posh/main/themes/schema.json
final_space: true
version: 2
blocks:
  - type: prompt
    alignment: left
    segments:
      - type: path
        style: powerline
        powerline_symbol: ""
        foreground: "#ffffff"
        background: "#61AFEF"
        properties:
          style: folder

toml

"$schema" = "https://raw.githubusercontent.com/JanDeDobbeleer/oh-my-posh/main/themes/schema.json"
final_space = true
version = 2

[[blocks]]
type = "prompt"
alignment = "left"

  [[blocks.segments]]
  type = "path"
  style = "powerline"
  powerline_symbol = ""
  foreground = "#ffffff"
  background = "#61AFEF"

    [blocks.segments.properties]
    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 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 print primary --config sample.json --shell uni

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.

tip

The --config flag can accept either a local filepath or a remotely hosted config file.

For example, the following is a valid --config flag: --config 'https://raw.githubusercontent.com/JanDeDobbeleer/oh-my-posh/main/themes/jandedobbeleer.omp.json'

General Settings

Name	Type	Description
final_space	boolean	when true adds a space at the end of the prompt
pwd	string	notify terminal of current working directory, values can be osc99, osc7, or osc51 depending on your terminal. Supports templates
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
accent_color	string	color - accent color, used as a fallback when the accent color is not supported
var	map[string]any	config variables to use in templates. Can be any value
shell_integration	boolean	enable shell integration using FinalTerm's OSC sequences. Works in bash, cmd (Clink v1.14.25+), fish, powershell and zsh
disable_cursor_positioning	boolean	disable fetching the cursor position in bash and zsh in case of unwanted side-effects
patch_pwsh_bleed	boolean	patch a PowerShell bug where the background colors bleed into the next line at the end of the buffer (can be removed when this is merged)

JSON Schema Validation

As mentioned above, Oh My Posh themes can utilize JSON Schema to validate their contents. Themes should include a link to the external schema document which prescribes the appropriate structure and contents for various elements. If your code editor is configured to use JSON Schema, it will compare your custom theme to the external document, and issue warnings for discrepancies.

For example, given the following code:

...
"segments": [
  {
    "type": "an_invalid_entry",
    "template": "{{ if gt .Code 0 }}\uf134{{ end }}",
  }
]
...

Warnings will be raised for type, since an_invalid_entry is not in the list of acceptable values, as well as for the entire segment item (enclosed in {}), since it lacks the required style key. Take advantage of these warnings, and ignore them at your peril.

Accepted Formats

Oh My Posh supports three file formats for themes: json, yaml, and toml.

Various converters exist to convert between these, although they aren't perfect and will require manual adjustment. Notably, the schema implementation for json is as follows:

{
  "$schema": "https://raw.githubusercontent.com/JanDeDobbeleer/oh-my-posh/main/themes/schema.json"
}

While for yaml:

# yaml-language-server: $schema=https://raw.githubusercontent.com/JanDeDobbeleer/oh-my-posh/main/themes/schema.json

Converters won't catch this change, so you will need to adjust manually.
