Depends on 3 packages(full list with versions):

base, echo, process

Used by 2 packages in lts-18.8(full list with versions):

echo, stack

`echo`

The base library exposes the hGetEcho and hSetEcho functions for querying and setting echo status, but unfortunately, neither function works with MinTTY consoles on Windows. This is a serious issue, since hGetEcho and hSetEcho are often used to disable input echoing when a program prompts for a password, so many programs will reveal your password as you type it on MinTTY!

This library provides an alternative interface which works with both MinTTY and other consoles. An example is included which demonstrates how one might prompt for a password using this library. To build it, make sure to configure with the -fexample flag.

Changes

0.1.4 [2021.02.17]

Use Trustworthy, not Safe, on GHC 7.2 to work around an old GHC bug.

0.1.3 [2017.01.30]

The MinTTY-detection portion of this library has been split off into mintty, on which echo now depends.

0.1.2 [2017.01.09]

Use more efficient implementation for bracketInputEcho.

0.1.1 [2017.01.07]

Use System.Win32.MinTTY from Win32-2.5 or later if possible.

0.1 [2016.12.22]

First version.
