Description

I'd like to get rid of the leading diamond. However, setting leading_diamond to null or "" does not work:

{                                      
    "type": "path",                    
    "style": "powerline",              
    "powerline_symbol": "",           
    "invert_powerline": false,         
    "foreground": "#100e23",           
    "foreground_templates": null,      
    "background": "#9191ff",           
    "background_templates": null,      
    "leading_diamond": null,             
    "trailing_diamond": "",            
    "properties": {                    
        "folder_separator_icon": "  ",
        "home_icon": "🏠",             
        "folder_icon": "…",            
        "style": "mixed"               
    }                                  
},                                     

Environment

• Oh my Posh version: 3.104.0
• Theme: customized theme based on powerline
• Operating System: Both Windows 10 and Debian 10
• Shell: Both PowerShell and pwsh (PowerShell for Linux)
• Terminal: Windows Terminal

Steps to Reproduce

1. Set leading_diamond to null or ""

Expected behavior: The leading diamond for path segment is gone.

Actual behavior: The leading diamond for path segment still exists.

(before pwsh: bash + powerline)

@tigerinus do you want the black triangle gone and be transparent, or the entire first powerline element gone and start with a rectangular background?

I want it to be gone.

It'd also be nice to learn how to make it transparent, for customization elsewhere.

Thanks!

[JanDeDobbeleer]

Alright, cool. The transparency should come out of the box unless your Windows Terminal has an acrylic or transparent background (bug on their backlog). To get rid of it completely, switch to either a diamond segment style and leave the leading diamond empty or take a plain style segment and populate the postfix property. What you chose depends on what comes after, so knowing the full config can help me get it right (there's more than one way because of reasons 😅).

You wouldn't happen to have a link to the issue, or maybe even a workaround, would you? I hate having to decide between a cool powerline symbol and a cool acrylic semi-transparent background 😥

@JanDeDobbeleer - Thanks!

Yes, it looks good now

Just wondering which part is the key for getting rid of the leading diamond?

[JanDeDobbeleer]

That would be switching to a diamond style segment. Powerline will always want to print the start and end symbol (the same) and is responsible for chaining traditional powerline segments.
