Debugging server initialization errors

In order to diagnose server initialization and non-parsing failures the fortls server can be run in a standalone debug mode. If you encounter errors during initialization that are not related to parsing follow the instructions below to help identify the cause/type of the error. Please include this output when submitting bugs related to server initialization failures.

Note: Debug information should not contain any subroutine/function contents. However, if the code you are working with is proprietary you may want to verify the output is clean before adding it to a public issue.

Running the server in debug mode

The server can be initialized for a given root directory in debug mode using the command below (if you installed FORTRAN Language Server using pip).

fortls --debug_rootpath=/path/to/root/dir
