Module doh::ops::term

Windows and non-Windows terminal utilities.

All functions in this module return something printable, and you should print their results, but do not assume that it's the returned text that does stuff, i.e. do not mix terminal manipulation and printing into the same call, and always flush after printing and before using the functions.

Examples

print!("{}{}", move_cursor_up(5), move_cursor_back(3));
print!("HLO");
stdout().flush().unwrap();
print!("{}", move_cursor_down(5));

Functions

move_cursor_back	Move the cursor n characters back (left).
move_cursor_down	Move the cursor n lines down.
move_cursor_up	Move the cursor n lines up.
open_file_picker	Show a file picker to let user choose a file.
save_file_picker	Show a file picker to let user choose where to save a file with the specified filename and optional extension.
show_cursor	Show/hide the cursor/caret.
