modify_ scripts and Windows

[Lockszmith-GH]

Windows, unlike MacOS/Linux, determins which script engine to launch based on extension only (no !# shebang pre-processing)

How do modify_ scripts invoke on a Windows machine?

Thanks for the page - I remembered reading it, and failed to find it before posting.

However, it doesn't really solve my issue...
An example: the file is without extension ~/.config/gohstty/config (or maybe it has an .ini or .json extension)

A modify_config or modify_config.tmpl can be a python script or a shell script or a powershell script.
Templating will allow me to pour the right script based on what's available, and I can add shebang on Linux/MacOS. On Windows though, no real solution.

Looks like either a Windows specific solution, or a system agnostic solution to identify the interpreter of the script is needed.

You would need to create a separate script for Windows because it relies on the extension (which is then stripped for the target file) e.g. modify_config.ps1. If you need to modify a file that also has an extension, you just use both extensions e.g. modify_config.toml.ps1.

An exception to this would be if it's a modify template, because these are not scripts.

Interesting, this indeed worked on my Windows machine:

PS ~\.local\share\chezmoi\chezmoi.roots\_home.windows\private_dot_config> cat .\modify_test.txt.ps1.tmpl
"Hello World"
PS ~\.local\share\chezmoi\chezmoi.roots\_home.windows\private_dot_config> chezmoi diff "$($env:USERPROFILE)\.config\test.txt"
diff --git a/.config/test.txt b/.config/test.txt

I'll try this tomorrow on one of my Linux machines, because this particular file will need to 'live on all platforms' - if that fails, I'll figure something out.
