line! :
{}
=> Result Str
[
EndOfFile,
StdinErr IOErr
]
Read a line from standard input.
This task will block the program from continuing until
stdinreceives a newline character (e.g. because the user pressed Enter in the terminal), so using it can result in the appearance of the programming having gotten stuck. It's often helpful to print a prompt first, so the user knows it's necessary to enter something before the program will continue.
bytes! :
{}
=> Result (List U8)
[
EndOfFile,
StdinErr IOErr
]
Read bytes from standard input. ‼️ This function can read no more than 16,384 bytes at a time. Use [readToEnd!] if you need more.
This is typically used in combintation with
Tty.enable_raw_mode!, which disables defaults terminal bevahiour and allows reading input without buffering until Enter key is pressed.
read_to_end! : {} => Result (List U8) [StdinErr IOErr]
Read all bytes from standard input until EOF in this source.
