[PowerShell] Delta works, but the Diff seems not do be correct - How to setup correctly

[GregOnNet]

Hi,

I think I miss something about setting up delta properly on Windows with PowerShell.
The diff is produced, but it looks a bit weird.
Or maybe, I have the wrong expectations.

When I execute git diff the diff shows the changes.
However, line 1 is shown twice.
I would have thought that line 1 is showing once, indicating that the name has been changed.
Currently, it looks like that one line has been removed and a new one was created.

Here is how I setup delta

winget install dandavison.delta
winget install jftuga.less

This less-version is exposed via PATH

Seems to be correct

less --version
less 668 (Spencer V8 regular expressions)

Here is how I configured delta in git

[core]
  pager = delta
  whitespace = cr-at-eol
  quotepath = false
  editor = code --wait
  eol = lf
  autocrlf = input

[interactive]
    diffFilter = delta --color-only --features=interactive

[delta]
    hyperlinks = true
    hyperlinks-file-link-format = "vscode://file/{path}:{line}"
    features = zebra-dark line-numbers decorations
    syntax-theme = Sublime Snazzy
    plus-style = syntax "#003800"
    minus-style = syntax "#3f0001"

[delta "decorations"]
    commit-decoration-style = bold yellow box ul
    file-style = bold yellow ul
    file-decoration-style = none
    hunk-header-decoration-style = cyan box ul

[delta "line-numbers"]
    line-numbers-left-style = cyan
    line-numbers-right-style = cyan
    line-numbers-minus-style = 124
    line-numbers-plus-style = 28

I am glad for any hint. :-)

I also checked with a TypeScript-File, because I thought, maybe it helps delta if more context like Syntax is present.
I see the same behaviour.
Syntax highlighting seems to to work either.
I activated diff-highlight in .gitconfig, btw.

[delta]
  navigate = true
  hyperlinks = true
  hyperlinks-file-link-format = "vscode://file/{path}:{line}"
- features = zebra-dark unobtrusive-line-numbers decorations
+ features = zebra-dark diff-highlight unobtrusive-line-numbers decorations

Hi @GregOnNet, that all looks correct. You get a "minus" line and a "plus" line, just like with normal git diff. For syntax highlighting you need to remove diff-highlight. In fact I'd recommend trying with minimal settings to start off with and then only adding more if you need them.

Thanks @dandavison ,

yeah my expectation was incorrect.
I got confused with --word-diff output.

I tried once more with more changes and now I also get the nice decoration, in which Method the changes has been made.
I also simplified my configuration as you suggested.

Great!
