make edlin understand a few important control keys
Hi Fredrik, > I've gotten some feedback from your review, > You need to add documentation under Erts-> "User's Guide" -> "tty - A > command line interface" > > You need to add testcase in interactive_shell_SUITE a simplified > example of how this testcase could look like; > ctrl_w_and_ctrl_u(_Conf) -> > rtnode([{putline,""}, {putline, "2."}, {getline, "2"}, > {putline,"xxx yy"++[$\^w]++"."}, {getline,"xxx"}, {putline,"xxx > yy"++[$\^u]++"z."}, {getline,"z"}],[]). Please find an updated version of the patch attached to this e-mail. I hope that you still accept it via e-mail because the former patch was sent the same way ;-). I have extended the documentation to list the new key combinations and added tests to make sure they work.

Please consider the environment before printing this message. >From ce4b827c78d18f39bb1146fd2959ffd7ae2b4bb6 Mon Sep 17 00:00:00 2001 From: Stefan Zegenhagen <[email protected]> Date: Mon, 6 May 2013 14:39:07 +0200 Subject: [PATCH] [EDLIN] support a few more control keys Add support for the following control keys that many users have become accustomed to: - <CTRL>+W : backward kill word - <CTRL>+U : backward kill line - <HOME> : goto start of line - <END> : goto end of line - <CTRL>+<LEFT> : backward word - <CTRL>+<RIGHT> : forward word It seems that the <CTRL>+<LEFT|RIGHT> control key sequences are different between terminal emulators, therefore a few possible combinations were added (similar to how libreadline is configured). Documentation and tests are extended to reflect the new functionality.
