why it does not work

[yananyin]

ls -l /home/yin/.local/bin/fprettify
-rwxr-xr-x 1 yin yin 225 Apr 22 15:05 /home/yin/.local/bin/fprettify


Formatter located in: /home/yin/.local/bin/fprettify
Formatter: fprettify not detected in your system.
                                Attempting to install now.

what settings are you using? my guess is that the formatter is detected but then overridden by your local settings. Also supply the extension version and vscode version please.

[gnikit]

can you please install the pre-release and also post if there are vscode settings (settings.json)

[yananyin]

It still prompts me in this way, even though I have switched to the pre-release version 3.4.2025041101.

it is my setting.json

{
    "fortran.formatting.formatter": "fprettify",
    "fortran.linter.includePaths": [
        "/home/yin/miniforge3/include/**"
    ],
    "fortran.formatting.path": "/home/yin/.local/bin/fprettify",
    "fortran.formatting.fprettifyArgs": [
        "-c", "/home/yin/.fprettify.rc"
    ]
}

[yananyin]

maybe, it does not work in wsl of Ubuntu-22.04 ?

[gnikit]

I think you just need to do: "fortran.formatting.path": "/home/yin/.local/bin", and the formatter's name will be appended internally.

Wow, it works. Thank you for your patient response.
