bug: UriError on wind variable rename

[EricStimpsonWSU]

Is there an existing issue for this?

• I have searched the existing issues

I have tried the Pre-Release of the extension.

• I have replicated the Issue in the latest Pre-Release

Description

I am trying to rename a variable in an F03 source file using the F2 key. When I enter the new variable name, I get an error '[UriError]: If a URI does not contain an authority component, then the path cannot begin with two slash characters ("//")'. I've tried several different variables in the same file, as well as a minimal file. The behavior is the same everywhere.

Screenshots

Expected Behaviour

Should rename the variable in all places

Version of Modern Fortran

v3.4.2024051001 (pre-release)

Version of Visual Studio Code

v1.89.1

Platform and Architecture

Windows

Additional Information

I had to manually set the path to fortls in my settings file, which looks like this:
"fortran.fortls.path": "c:/Users/xxx/miniconda3/envs/general/scripts/fortls"

The version of fortls is v3.0.0 and python is 3.11.7. I also checked the fortls github to see if there were UriErrors reported there

Can you try and get the same error with the fortls command line interface. It should be something like this.
What is the output of the command.

fortls --debug_filepath your_file.f90 --debug_rootpath ./project_root_dir --debug_rename newName --debug_line X --debug_char Y

Where debug_line and debug_char are the line and column numbers (any column number that is within your variable name will do) of the variable.

[gnikit]

Also turn on the Debug logging and post the complete output of the Modern Fortran OUTPUT channel (with the error).

The command line didn't report any errors and the output showed the lines affected with the appropriate changes.

Here is the output:

Also turn on the Debug logging and post the complete output of the Modern Fortran OUTPUT channel (with the error).

The following is the output from Modern Fortran. No additional output is generated when I try to rename a variable, however:

I don't [currently] have gfortran installed locally in windows, as I am accessing the compiler only from WSL. However, if the extension wants a local install of gfortran, I can try that.

[gnikit]

fortls seems to be working okay. To be sure, using the the following VS Code settings, replicate in VS Code the behaviour that caused the error to be thrown and then post the complete output of the Modern Fortran. From the output you posted above I things seem to be working as expected.

Settings

  "fortran.logging.level": "Debug",
  "fortran.fortls.extraArgs": [
    "--debug_log"
  ],
