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][segments]. Keep reading to
understand how to configure a segment.

| `type`                     | `string`     | takes the `string` value referencing which segment logic it needs to run (see [segments][segments] for possible values)                                                                                                                                                                                                    |
| `style`                    | `string`     | see [Style][style] below. Possible values:<ul><li>`powerline`</li><li>`plain`</li><li>`diamond`</li><li>`accordion`</li><li>a go [text/template][go-text-template] [template][templates] resolving to the above values</li></ul>                                                                                           |
| `powerline_symbol`         | `string`     | character to use when `"style": "powerline"`                                                                                                                                                                                                                                                                               |
| `leading_powerline_symbol` | `string`     | when `"style": "powerline"` we use an ANSI hack to invert the `powerline_symbol` to create a transparent glyph. This gives the best alignment, but might not work in every terminal. If you see black elements at the start of powerline segments, you can set this to the "opening" version of the `powerline_symbol`.    |
| `invert_powerline`         | `boolean`    | if `true` swaps the foreground and background colors. Can be useful when the character you want does not exist in the perfectly mirrored variant for example - defaults to `false`                                                                                                                                         |

## Style

Style defines how a prompt is rendered. Looking at the most prompt
themes out there, we identified 4 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.

When you see black triangles (or other characters depending on the `powerline_symbol` you use) at the start of a segment,
you can set `leading_powerline_symbol` to the "opening" version of the `powerline_symbol`.
This will not use the inverted ANSI hack we have in place as that's not supported in every terminal. You might need to tweak
your font settings to get the best alignment.

### Plain

Simple. Colored text on a transparent background. Make sure to set `foreground` for maximum enjoyment.

### Diamond

While Powerline works great with a 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.

### Accordion

Same as Powerline except that it will display even when disabled, but without text. That way it seems
as if the segment is not expanded, just like an accordion.

## 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 shared ones being used by the engine which allow
you to customize the output even more.

### Shared properties

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

| Name              | Type       |
| ----------------- | ---------- |
| `include_folders` | `[]string` |
| `exclude_folders` | `[]string` |

#### 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.

```json
"include_folders": [
  "/Users/posh/Projects"
]
```

```json
"exclude_folders": [
  "/Users/posh/Projects"
]
```

The strings specified in these properties are evaluated as [regular expressions][regex]. 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`.

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

You can also combine these properties:

```json
"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.

## Hiding segments

### Conditionally

To hide a whole segment including the leading and trailing symbol based on a [template][templates], the template must
**evaluate to an empty string**. This can be achieved with conditional statements (`if`). The example below will render
a diamond segment, only if the environment variable `POSH_ENV` is not empty.

Only spaces are excluded, meaning you can still add line breaks and tabs if that is something you're after.

```json
{
  "type": "text",
  "style": "diamond",
  "leading_diamond": " \ue0b6",
  "trailing_diamond": "\ue0b4",
  "foreground": "#ffffff",
  "background": "#d53c14",
  "template": "{{ if .Env.POSH_ENV }} \uf8c5 {{ .Env.POSH_ENV }} {{ end }}"
}
```

### On the fly

Sometimes run into a situation where you don't want to see a specific segment but the use-case does not justify
using a conditional template. In this case you can use the `oh-my-posh toggle <type>` command to toggle the
segment on or off. This works on a **per shell session basis**, meaning that if you toggle a segment off in one instance
of a shell, it will not disable in the others.

To list the currently toggled segments, use `oh-my-posh get toggles`.
