associate file types with the editor

[gdementen]

Notably .h5 but probably also feather, .laf and possibly others

Here are two commands, which when run in an Administrator launched command prompt, achieves that for .h5 files.

assoc .h5=HDF5
ftype HDF5="C:\soft\Miniconda3\pythonw.exe" "C:\soft\Miniconda3\cwp.py" "C:\soft\Miniconda3" "C:\soft\Miniconda3\pythonw.exe" "C:\soft\Miniconda3\Scripts\larray-editor-script.py" "%1"

I wonder if cwp.py is even necessary when larrayenv has been installed in the base environment. IF not, this would simplify to:

ftype HDF5="C:\soft\Miniconda3\pythonw.exe" "C:\soft\Miniconda3\Scripts\larray-editor-script.py" "%1"

Or, for a specific conda environment:

ftype HDF5="C:\soft\Miniconda3\pythonw.exe" "C:\soft\Miniconda3\cwp.py" "C:\soft\Miniconda3\envs\py312larrayenv" "C:\soft\Miniconda3\envs\py312larrayenv\pythonw.exe" "C:\soft\Miniconda3\envs\py312larrayenv\Scripts\larray-editor-script.py" "%1"

yvda also suggested going via registry, which might provide more options:

Windows Registry Editor Version 5.00
 
; Associate .h5 files with a custom handler
[HKEY_CLASSES_ROOT\.h5]
@="h5file"
"Content Type"="application/x-hdf5"
 
; Define h5file as a recognized file type
[HKEY_CLASSES_ROOT\h5file]
@="HDF5 File"
 
; Add an "Open" command to h5file
[HKEY_CLASSES_ROOT\h5file\shell\open]
@="Open with Larray Editor"
 
[HKEY_CLASSES_ROOT\h5file\shell\open\command]
@="\"C:\\soft\\Miniconda3\\pythonw.exe\" \"C:\\soft\\Miniconda3\\cwp.py\" \"C:\\soft\\Miniconda3\" \"C:\\soft\\Miniconda3\\pythonw.exe\" \"C:\\soft\\Miniconda3\\Scripts\\larray-editor-script.py\" \"%1\""

save file.reg -> cmd (as admin) -> regedit /s "c:/file/file.reg"

According to https://superuser.com/a/794467, using the registry option could also be used to change the icon for those files, which would be nicer than having the Python icon we now get.
