| | Find position (in the string) of a filename's trailing slash.
|
| |
| subroutine, public | filename_path (fname, path) |
| | Extract the path to a file.
|
| |
| subroutine, public | filename_name (fname, name) |
| | Extract the base name of a file (without path and suffix)

| subroutine, public | filename_split (fname, path, name, suffix) |
| | Extract file name components.
|
| |
| subroutine, public | filename_chsuffix (fname, new_fname, new_suffix) |
| | Change a filename's suffix.
|
| |
| recursive subroutine, public | mkdir (path, mode) |
| | Recursively create a directory and all parent directories if they do not exist. This should be safer than the ‘execute_command_line('mkdir -p ’ // path)approach, which can be used to execute arbitrary code ifpath` is not properly sanitized.
|
| |
| integer function, public | extract_fld_file_index (fld_filename, default_index) |
| | Extracts the index of a field file. For example, "myfield.f00045" will return 45. If the suffix of the file name is invalid, returns a default index value.

| |
| character(len=100) function, dimension(:), allocatable, public | split_string (string, delimiter) |
| | Split a string based on delimiter (tokenizer) OBS: very hacky, this should really be improved, it is rather embarrasing code.
|
| |
| pure integer function, public | linear_index (i, j, k, l, lx, ly, lz) |
| | Compute the address of a (i,j,k,l) array with sizes (1:lx, 1:ly, 1:lz, :)
|
| |
| pure integer function, dimension(4), public | nonlinear_index (linear_index, lx, ly, lz) |
| | Compute (i,j,k,l) array given linear index with sizes (1:lx, 1:ly, 1:lz, :)
