Settings compiler flags with fortls?

[kshar-75]

Hey, the first thing I've noticed with my first "Hello World!" program in fortran is that for some reason the editor places a [-Wtabs] warning on the print statement. This is an issue because this type of syntax is extremely common among fortran programmers. How do I modify the fortls settings so that I can pick compiler flags of my own?

That is a gfortran warning coming from the linter (I assume you are using VS Code as you editor) not fortls i.e. this repo. Tabs in Fortran are not considered part of the standard, use spaces instead or disable the warning by -Wno-tabs

You can use cmake. Fortls should only provide autocomplete.

file(GLOB_RECURSE SOURCE_FILES *.f90)
message("Source files: ${SOURCE_FILES}")
add_executable(${PROJECT_NAME} ${SOURCE_FILES})
target_compile_options(${PROJECT_NAME} 
    PRIVATE
        -Wno-line-truncation
        -Wno-unused-variable
        -Wno-integer-division
        -Wno-conversion
        -Wno-tabs
        -ffree-line-length-none
)

fortls does not "only provide autocomplete", it offers a lot more than just completions. For a complete list please advise the docs: https://fortls.fortran-lang.org/features.html
