/home/runner/work/HighMap/HighMap/HighMap/include/highmap/export.hpp

Adds a suffix to the filename of a given file path.

Adds a suffix to the filename of a given file path.This function appends a given suffix to the stem (base name without extension) of a file while preserving the original directory and file extension.

Parameters

file_path	The original file path.
suffix	The suffix to append to the filename.

Returns

A new std::filesystem::path with the modified filename.

Note

If the input file has no extension, the suffix is added directly to the filename.

 std::filesystem::path path = "example.txt";
std::filesystem::path new_path = add_filename_suffix(path, "_backup");
std::cout << new_path; // Outputs "example_backup.txt"
