Add Segment

Create the logic#

Add a new file following this convention: new_segment.go. Ensure new is a single verb indicating the context the segment renders.

You can use the following template as a guide.

package main
type new struct {
props *properties
env environmentInfo
}
const (
//NewProp switches something
NewProp Property = "newprop"
)
func (n *new) enabled() bool {
true
}
func (n *new) string() string {
newText := n.props.getString(NewProp, "\uEFF1")
return newText
}
func (n *new) init(props *properties, env environmentInfo) {
n.props = props
n.env = env
}

When it comes to properties, make sure to use the UTF32 representation (e.g. "\uEFF1") rather than the icon itself. This will facilitate the review process as not all environments display the icons based on the font being used. You can find these values and query for icons easily at Nerd Fonts.

For each segment, there's a single test file ensuring the functionality going forward. The convention is new_segment_test.go, have a look at existing segment tests for inspiration.

Create a name for your Segment#

segment.go contains the list of available SegmentType's, which gives them a name we can map from the .json themes.

Add your segment.

//New is brand new
New SegmentType = "new"

Add the SegmentType mapping#

Map your SegmentType to your Segment in the mapSegmentWithWriter function.

New: &new{},

Test your functionality#

Even with unit tests, it's a good idea to build and validate the changes:

go build -o $GOPATH/bin/oh-my-posh

Add the documentation#

Create a new markdown file underneath the docs/docs folder called segment-new.md. Use the following template as a guide.

---
id: new
title: New
sidebar_label: New
---
## What
Display something new.
## Sample Configuration
```json
{
"type": "new",
"style": "powerline",
"powerline_symbol": "\uE0B0",
"foreground": "#193549",
"background": "#ffeb3b",
"properties": {
"newprop": "\uEFF1"
}
}
```
## Properties
- newprop: `string` - the new text to show - defaults to `\uEFF1`

Map the new documentation in the sidebar#

Open sidebars.js and add your document id (new) to the items of the Segments category.

Add the JSON schema#

Edit the themes/schema.json file to add your segment.

At $.definitions.segment.properties.type.enum, add your SegmentType to the array:

new,

At $.definitions.segment.allOf, add your segment details:

{
"if": {
"properties": {
"type": { "const": "new" }
}
},
"then": {
"title": "Display something new",
"description": "https://ohmyposh.dev/docs/new",
"properties": {
"properties": {
"properties": {
"nwprop": {
"type": "string",
"title": "New Prop",
"description": "the new text to show",
"default": "\uEFF1"
}
}
}
}
}
}
