basic_file_routines.f90

[dkolom]

File src/file_io/basic_file_routines.f90 is now empty. Why was it necessary to move its contents somewhere else? Where? Do we need this empty file any longer?

you're right - this file is no longer needed.
The routines have been moved to module_helpers.f90. As the insect module is supposed to become stand-alone we need to minimize its dependencies and group them together so that transfer to other codes is easier.
The file src/file_io/basic_file_routines.f90 contained external routines (without interface and module), hence some compilers require the definition of an explicit interface to use character(len=*)

this has to be done anywhere these functions are used and is tedious and error-prone. note still many compilers have trouble with different-length strings (which is why we have strlen=120 in vars.f90).
After some crashes, I thought it would be better to combine the functions with module_helpers.90.

I deleted the empty file.
