How to take the value after typing one character in redline (Char?) Without ENTER

General Usage

Is there a way for the variable var to take the value after typing one character in redline (Char?) without pressing Enter? Something like

var = readline (:: Char?)

(I am doing a quick one-touch input interface)

I think just reading a char from stdin should work.

Like read(stdin, Char)

julia> var=read(stdin, Char)
aaa
'a': ASCII/Unicode U+0061 (category Ll: Le

julia> aa
ERROR: UndefVarError: aa not defined

After typing one char nothink :confused:

It is necessary for only one character to have the same reaction as for the character(s) + Enter now.
typing one char = automatlicly to closing function.
