Wouldn't have imagined doing part two in a week's time, but here we are again!

## Features
|
|
|
|
### CLI interface (also #2)
|
|
|
|
In the [previous post][blog-1] I highlighted some changes in the CLI interface. Turns out I could make it
|
|
even more straightfoward. As Oh My Posh is a prompt generating utility, the `prompt` command
|
|
doesn't make sense as that's implied. It has been removed, although it **will keep working** to
|
|
not break existing functionality on upgrade.
|
|
|
|
#### Init
|
|
|
|
The following initialization:
|
|
|
|
```powershell
|
|
oh-my-posh prompt init pwsh | Invoke-Expression
|
|
```
|
|
|
|
now becomes:
|
|
|
|
```powershell
|
|
oh-my-posh init pwsh | Invoke-Expression
|
|
```
|
|
|
|
#### Debug
|
|
|
|
To debug Oh My Posh, you can simply use the `debug` command. It's smart enough to know your config
|
|
so you don't have to specify the `--config` option.
|
|
|
|
```powershell
|
|
oh-my-posh debug
|
|
```
|
|
|
|
### Fish shell
|
|
|
|
We already supported [fish shell][fish] for a while, but we stepped up the game. I started using fish
|
|
as my primary shell, so obviously it couldn't stay behind. I suggest you also have
|
|
a go at it, it's a very enjoyable experience.
|
|
|
|
But OK, what changed? We now support the following out of the box:
|
|
|
|
- [right prompt][right]
|
|
- [transient prompt][transient]
|
|
- [tooltips][tooltips]
|
|
|
|
It seems there's **_no support (yet) for a secondary prompt in fish_**, once that's available we can easily add that too.
|
|
To enjoy all of this, upgrade to the latest and initialize fish by adding the following line to `~/.config/fish/config.fish`:
|
|
|
|
```bash
|
|
oh-my-posh init fish | source
|
|
```
|
|
|
|
### Transient prompt
|
|
|
|
Speaking of [transient][transient], it learned some new tricks. First, you can now use the `.Code` property to work with the last
|
|
command's error code (if any) in the template. This can for example be used to color the transient prompt
|
|
differently when the last command failed. That did imply we also needed support for color [templates][color-templates], as that
|
|
wasn't possible just yet. Say no more, we now have a [transient prompt][transient] that supports color templates.
|
|
|
|
```json
|
|
"transient_prompt": {
|
|
"background": "p:yellow",
|
|
"background_templates": [
|
|
"{{ if gt .Code 0 }}p:red{{ end }}"
|
|
],
|
|
"foreground": "p:black",
|
|
"foreground_templates": [
|
|
"{{ if gt .Code 0 }}p:white{{ end }}"
|
|
],
|
|
"template": "<background,transparent>\ue0b6</> {{ .Folder }} <background,transparent>\ue0b0</><,transparent> </>"
|
|
}
|
|
```
|
|
|
|
Which produces the following result:
|
|
|
|
|
|
|
|
### Config version 2
|
|
|
|
Remember we did a migration to config version 1 in the beginning of the year? Well, we did a migration to version 2.
|
|
Looking at Oh My Posh's architecture, the different prompts (transient, secondary, ...) were moving closer to the model used
|
|
by segments. The only difference was that `template` wasn't a property, but a field of those prompts. As **all segments
|
|
now have template support**, it was a no-brainer to align both models and do a migration to config version 2 so nobody
|
|
would have any manual work in the process.
|
|
|
|
The following segment definition:
|
|
|
|
```json
|
|
{
|
|
"background": "#9A348E",
|
|
"foreground": "#ffffff",
|
|
"leading_diamond": "\ue0b6",
|
|
"properties": {
|
|
"template": "{{ .UserName }} "
|
|
},
|
|
"style": "diamond",
|
|
"type": "session"
|
|
}
|
|
```
|
|
|
|
Will now be migrated to this for version 2:
|
|
|
|
```json
|
|
{
|
|
"background": "#9A348E",
|
|
"foreground": "#ffffff",
|
|
"leading_diamond": "\ue0b6",
|
|
"style": "diamond",
|
|
"template": "{{ .UserName }} ",
|
|
"type": "session"
|
|
}
|
|
```
|
|
|
|
## Go 1.18
|
|
|
|
Not something that impacts the end user directly, but maybe interesting to know is that Oh My Posh is now
|
|
using [go 1.18][go1.18] by default. This brings obvious language improvements and a few new features we can play with.
|
|
The most notable is generics, but it doesn't seem like we can benefit just yet as it's not yet supported
|
|
for methods, and that's the main use-case for us.
|
|
|
|
Nontheless, it's good to stay up-to-date, if you notice any quirks though, be sure to let us know!
|
|
|
|
That's it for this week, see you for the next one 🤞🏻

_Keep that prompt posh everyone! _
