bug(syntax): Syntax Problem between Freeform and Fixedform

[zhongxiang117]

Is there an existing issue for this?

• I have searched the existing issues

Description

I noticed that "the configuration of the selection language mode" does not work between FortranFreeform and FortranFixedform, if the unusual file extension is used.

For my seeing, the output info for both of them are:

["INFO" - 11:25:36 AM] using linter: gfortran located in: /usr/bin/gfortran
["INFO" - 11:25:36 AM] Linter.arguments:
-Wall
-ffree-line-length-none
-ffixed-line-length-none

It is not correct, instead, for FortranFreeform, the Linter.arguments should be -ffree-form.

Screenshots

Code Example

! file should be with extension `.fpp` or any others, but not `.f90`

! shoud be freeform
program test
    print*, 'good'
end

Fortran Version (Free/Fixed Form)

Free Form e.g. F90+

Version of Modern Fortran

v3.2.0

Version of Visual Studio Code

v1.85.0

Platform and Architecture

Linux (Ubuntu)

Additional Information

gfortran version v9.4.0 & v11.4.0

Possible Solution:

Add "builtin" argument -ffree-form when language mode FortranFreeform is selected.

This is a linting issue. To make better sense of it, use the pre-release and provide the compiler version. fpp is registered as FreeFormFortran so I suspect you are running in an already resolved bug from the old release (you might have noticed I haven't made stable release in a while, completely unrelated to the stability of the pre-release and more related with admin things that are still pending!)

Sorry, let me firstly confirm this, the “linting issue”, is the linter builtin inside compiler? If so, I have the settings like:

"fortran.linter.compiler": "gfortran",
"fortran.linter.compilerPath": "/home/xiang/Applications/miniconda3core/envs/xutils/bin/gfortran",

then please have a look on following screenshot,

As you will see, it still does not work at all.

Or you are mentioning different things, the linter, where can I find or compile it (cause I really don’t know whether it is a different thing rather than compiler itself)?
