rawterm/begin cfunction source 
(rawterm/begin &opt on-winch)

Begin raw terminal functionality. Return a stream that can be read from to get input.
rawterm/buffer-traverse cfunction source 
(rawterm/buffer-traverse bytes index delta &opt skip-zerowidth)

Move to a new position in a buffer from index by incrementing by `delta` codepoints. Can also skip zero-width codepoints if desired.
rawterm/ctrl-z cfunction source 
(rawterm/ctrl-z)

A handler that a user can use to handle ctrl-z from input to suspend the current process.
rawterm/end cfunction source 
(rawterm/end)

End raw terminal functionality.
rawterm/getch cfunction source 
(rawterm/getch &opt into)

Get a byte of input from stdin, without blocking if possible. Returns a buffer.
rawterm/isatty cfunction source 
(rawterm/isatty)

Check if the current stdin is a tty.
rawterm/monowidth cfunction source 
(rawterm/monowidth bytes &opt start-index end-index)

Measure the monospace width of a string.
rawterm/rune-monowidth cfunction source 
(rawterm/rune-monowidth rune)

Get the monospace width of a rune. Returns either 0, 1, or 2.
rawterm/size cfunction source 
(rawterm/size)

Get the number of rows and columns visible in the terminal as tuple [rows cols]
rawterm/slice-monowidth cfunction source 
(rawterm/slice-monowidth bytes columns &opt start-index into)

Get a byte slice that will fit into a number of columns.
