| 4 | |
| 5 | <p>The goal of the Toybox project is to create simple implementations of all |
| 6 | the important Linux command line utilities. These implementations should |
| 7 | be small (the entire project should total less than a megabyte, uncompressed), |
| 8 | fast, simple, and correctly implemented (which is related to standards |
| 9 | compliance, but isn't quite the same thing). Click for |
| 10 | <a href="design.html">more about the design goals</a></p> |
| 11 | |
| 12 | <p>Toybox has configurable levels of functionality, and should scale from tiny |
| 13 | embedded systems up to full general purpose desktop and development |
Rob Landley | 4c2484f | 2012-01-22 19:41:42 -0600 | [diff] [blame] | 14 | environments. The author plans to install it on his Android phone in |
| 15 | place of Toolbox, and the |
| 16 | <a href=/aboriginal>Aboriginal Linux</a> project is trying to get a complete |
Rob Landley | e258af3 | 2008-01-05 18:09:49 -0600 | [diff] [blame] | 17 | Linux system to rebuild itself from source code using toybox.</p> |
| 18 | |
Rob Landley | 1208ca7 | 2011-11-15 03:01:41 -0600 | [diff] [blame] | 19 | <p>Toybox is <a href=license.html>released under a simple 2-clause BSD-style |
| 20 | license</a>.</p> |
Rob Landley | e258af3 | 2008-01-05 18:09:49 -0600 | [diff] [blame] | 21 | |
| 22 | <p>Toybox can be built as a single "swiss army knife" executable (ala BusyBox |
| 23 | or Red Hat's Nash), or each command can be built as a traditional independent |
| 24 | executable.</p> |
| 25 | |
| 26 | <b><h2><a name="status" />What commands are implemented?</h2></b> |
| 27 | |
| 28 | <p>The current list of commands implemented by toybox is at the top of the |
Rob Landley | 1208ca7 | 2011-11-15 03:01:41 -0600 | [diff] [blame] | 29 | <a href=news.html>news page</a>. That list is updated when new commands |
Rob Landley | 4c2484f | 2012-01-22 19:41:42 -0600 | [diff] [blame] | 30 | go in. The list of commands yet to implement for the 1.0 release is in the |
| 31 | <a href=todo.txt>todo list</a>.</p> |
Rob Landley | e258af3 | 2008-01-05 18:09:49 -0600 | [diff] [blame] | 32 | |
| 33 | <p>In general, configuring toybox for "defconfig" enables all the commands |
| 34 | compete enough to be useful. Configuring "allyesconfig" enables partially |
| 35 | implemented commands as well.</p> |
| 36 | |
Rob Landley | 4c2484f | 2012-01-22 19:41:42 -0600 | [diff] [blame] | 37 | <p>Several toybox commands can do things other vesions can't. For example |
| 38 | the toybox "df" isn't confused by initramfs the way other df implementations |
Rob Landley | bd91551 | 2008-01-07 20:28:26 -0600 | [diff] [blame] | 39 | are. If initramfs is visible, df shows it like any other mount point.</p> |

Rob Landley | e258af3 | 2008-01-05 18:09:49 -0600 | [diff] [blame] | 41 | <b><h3>Command Shell</h3></b> |
| 42 | <p>The Toybox Shell (toysh) aims to be a reasonable bash replacement. It |
| 43 | implements the "sh" and "toysh" commands, plus the built-in commands "cd" and |
| 44 | "exit". This is the largest single sub-project in toybox.</p> |
| 45 | |
| 46 | <p>The following additional commands may be built into the shell (but not as |
| 47 | separate executables): cd, exit, if, while, for, function, fg, bg, jobs, source, |

| 53 | <h2><a name="commands" />Which commands are planned?</h2> |
| 54 | |
| 55 | <p>The toybox <a href=todo.txt>todo list</a> mentions many potential commands |
| 56 | which may be added to this project. (Whether that file is readable by anybody |
Rob Landley | 4c2484f | 2012-01-22 19:41:42 -0600 | [diff] [blame] | 57 | but the project's maintainer is open to debate.) The roadmap wiki in the |
| 58 | nav bar has a more human readable version.</p> |

Rob Landley | 4c2484f | 2012-01-22 19:41:42 -0600 | [diff] [blame] | 61 | Linux kernel, toybox, C library (such as uClibc), and a compiler (such as |
| 62 | tinycc) can rebuild itself from source code.</p> |

| 64 | <b><h3>Relevant Standards</h3></b> |
| 65 | |
| 66 | <p>Most commands are implemented according to |
Rob Landley | 4c2484f | 2012-01-22 19:41:42 -0600 | [diff] [blame] | 67 | <a href=http://opengroup.org/onlinepubs/9699919799/idx/utilities.html>The |
| 68 | Single Unix Specification version 4</a> where applicable. This does not mean |
Rob Landley | e258af3 | 2008-01-05 18:09:49 -0600 | [diff] [blame] | 69 | that Toybox is implementing every SUSv3 utility: some such as SCCS and ed are |
| 70 | obsolete, while others such as c99 are outside the scope of the project. |
| 71 | Toybox also isn't implementing full internationalization support: it should be |
| 72 | 8-bit clean and handle UTF-8, but otherwise we leave this to X11 and higher |
| 73 | layers. And some things (like $CDPATH support in "cd") await a good |
| 74 | explanation of why to bother with them. (The standard provides an important |
| 75 | frame of reference, but is not infallable set of commandments to be blindly |
| 76 | obeyed.)</p> |
| 77 | |
| 78 | <p>The other major sources of commands are the Linux man pages, and testing |
| 79 | the behavior of existing commands (although not generally looking at their |
Rob Landley | 4c2484f | 2012-01-22 19:41:42 -0600 | [diff] [blame] | 80 | source code), including the commands in Android's toolbox. SUSv4 does not |
| 81 | include many basic commands such as "mount", "init", and "mke2fs", which are |
| 82 | kind of nice to have.</p> |

| 110 | from black to grey, presumably in celebration. It was fun while it lasted...)</p> |
