Shell: Move line editing to a separate class. To be clear, there isn't really any line editing yet. But there is going to be, so let's have it in its own class. 2019-05-07 01:39:10 +02:00			`#pragma once`

AK: Rename <AK/AKString.h> to <AK/String.h> This was a workaround to be able to build on case-insensitive file systems where it might get confused about <string.h> vs <String.h>. Let's just not support building that way, so String.h can have an objectively nicer name. :^) 2019-09-06 15:34:26 +02:00			`#include <AK/String.h>`
Shell: Added `pushd`, `popd` and `dirs` builtins Added a few builtin functions to the shell to make navigating a bit easier in the terminal. `pushd` allows a user to "push" the current directory to the directory stack, and then `cd` to the new directory. `popd` allows the used to take the directory on the top of the stack off before `cd`'ing to it. `dirs` gives the state of the current directory stack. This is only a partial implementation of the `bash` version (gnu.org/software/bash/manual/html_node/Directory-Stack-Builtins.html) , and doesn't include any of the +N or -N commands as of yet. 2019-09-15 18:54:20 +10:00			`#include <AK/Vector.h>`

Shell: Update termios settings to match line discipline. Shell.cpp uses its own line discipline which handles echoing and line editing. Because of this we disable ICANON and ECHO so that we don't get duplicate characters or weird line editing errors. We also revert these settings just before running a command. This is so that commands may run with proper line editing and echoing. 2019-10-20 20:02:55 +13:00			`struct termios default_termios;`

Shell: Handle SIGWINCH to get a nice behavior when resizing. When resizing the terminal, we now clear the entire current line and reset the shell's LineEditor input state. This makes it look and feel kinda the same as xterm. Fixes #286. 2019-07-08 19:04:13 +02:00			`bool was_resized { false };`
Shell: Add support for special parameter that expands to return-code of last program executed 2019-09-08 20:00:35 -05:00			`int last_return_code { 0 };`
