Commands that need to modify the running user structure defined in scli.h |
should reside here. They (will) have a slightly different prototype that |
allows passing the user structure to them for ease of modifications. |
Examples of what should be a built-in and not a module would be: |
cd (cliuser_t->cwd needs to be updated) |
In the future, more user preferences will be set via built-in commands, |
such as the formatting of the prompt string (HelenOS doesn't yet have |
an environment, much less PS*, even if it did we'd likely do it a little |
differently). |
.... etc. |
Anything that does _not_ need to use this structure should be included |
as a module, not a built in. If you want to include a new command, there |
is a 99% chance that you want it to be a module. |

Modules are commands or full programs (anything can be made into a module |
that can return int type) should go here. Note, modules do not (can not) |
update or read cliuser_t. |
Stuff that needs to write to the user structures contained in scli.h should |
be made as built-in commands, not modules, but there are very few times when |
you would want to do that. |
See the README file in the bdsh root directory for a quick overview of how to |
write a new command, or convert an existig stand-alone program into a module |
for BDSH. |

cat << EOF |
\`$PROGNAME' generates skeletal command files to simplify adding commands |
Usage: $PROGNAME [options] <location> |
Options: |
-n, --name Name of the command (default: ${def}) |
-d, --desc Short (20 30 chars) description of the command |
(def: "The $def command") |
-e, --entry Entry function of the command (def: cmd_${def}) |
-h, --help-entry Entry function for command help (def: help_cmd_${def}) |
-a, --alias Alias (nickname) for this command (def: none) |
-r, --restrict Restriction level (interactive, non-interactive, both) |
(def: module is both, builtin is interactive only) |
-t, --type Type of command (module or builtin) (def: module) |
-H, --help This help summary |
-V, --version Print $PROGNAME version and exit normally |
Notes: |
You must supply at least the name of the command. |
If you do not specify a location (i.e. modules/foo), the command will be |
created in modules/command_name or builtins/command_name depending on your |
selection. |
This script will only create skeletal files and inform you what headers |
need to be modified to incorporate the command. You will also have to |
manually update the main Makefile. |
This script is intended only to be a convenience for developers. Example use: |
$PROGNAME -n foo -d "Foo power" -a bar -r both -t module modules/foo |
The example would generate a modular command named 'foo', which is also |
reached by typing 'bar' and available in either interactive or noninteractive |
mode. |
Skeletal files do *not* depend on the autoconf generated "config.h" unless you |
include it. This may or may not be desirable depending on your use. |

BDSH - The Brain Dead Shell | Design Documentation |
-------------------------------------------------- |
Overview: |
========= |
BDSH was written as a drop in command line interface for HelenOS to permit |
interactive access to persistent file systems in development. BDSH was |
written from scratch with a very limited userspace standard C library in |
mind. Much like the popular Busybox program, BDSH provides a very limited |
shell with limited common UNIX creature comforts built in. |
Porting Busybox (and by extension ASH) would have taken much longer to |
complete, much less make stable due to stark differences between Linux and |
Spartan with regards to IPC, term I/O and process creation. BDSH was written |
and made stable within the space of less than 30 days. |
BDSH will eventually evolve and be refined into the HelenOS equivalent |
of Busybox. While BDSH is now very intrinsic to HelenOS, its structure and |
use of strictly lower level functions makes it extremely easy to port. |
Design: |
======= |
BDSH is made up of three basic components: |
1. Main i/o, error handling and task management |
2. The builtin sub system |
3. The module sub system |
The main part handles user input, reports errors, spawns external tasks and |
provides a convenient entry point for built-in and modular commands. A simple |
structure, cliuser_t keeps track of the user's vitals, such as their current |
working directory (and eventually uid, home directory, etc if they apply). |
This part defines and exposes all functions that are not intrinsic to a |
certain built in or modular command. For instance: string handlers, |
module/builtin search and launch functions, error handlers and other things |
can be found here. |
Builtin commands are commands that must have access to cliuser_t, which is |
not exposed to modular commands. For instance, the 'cd' command must update |
the current working directory, which is stored in cliuser_t. As such, the |
entry types for builtin commands are slightly different. |
Modular commands do not need anything more than the basic functions that are |
exposed by default. They do not need to modify cliuser_t, they are just self |
contained. A modular command could very easily be made into a stand alone |
program, likewise any stand alone program could easily become a modular |
command. |
Both modular and builtin commands share two things in common. Both must have |
two entry points, one to invoke the command and one to invoke a help display |
for the command. Exec (main()) entry points are int * and are expected to |
return a value. Help entry points are void *, no return value is expected. |
They are typed as such (from cmds.h): |
/* Types for module command entry and help */ |
typedef int * (* mod_entry_t)(char **); |
typedef void * (* mod_help_t)(unsigned int); |
/* Built-in commands need to be able to modify cliuser_t */ |
typedef int * (* builtin_entry_t)(char **, cliuser_t *); |
typedef void * (* builtin_help_t)(unsigned int); |
As you can see, both modular and builtin commands expect an array of |
arguments, however bulitins also expect to be pointed to cliuser_t. |
Both are defined with the same simple structure: |
/* Module structure */ |
typedef struct { |
char *name; /* Name of the command */ |
char *desc; /* Description of the command */ |
mod_entry_t entry; /* Command (exec) entry function */ |
mod_help_t help; /* Command (help) entry function */ |
int restricted; /* Restricts to interactive/non-interactive only */ |
} module_t; |
NOTE: Builtin commands may grow in this respect, that is why they are |
defined separately. |
Builtins, of course, would use the builtin_entry_t type. The name of the |
command is used to associate user input to a possible entry point. The |
description is a short (40 - 60 chars) summary of what the command does. Both |
entry points are then defined, and the restrict value is used to determine a |
commands availability. |
Restriction levels are easy, a command is either available exclusively within |
interactive mode, exclusively within non-interactive mode or both. If you are |
looking at a prompt, you are in interactive mode. If you issue a command like |
this: |
/sbin/bdsh command [arg1] [arg2] |
... you are in non interactive mode. This is done when you need to force the |
parent shell to be the one who actually handles the command, or ensure that |
/sbin/ls was used in lieu of the built in 'ls' when in non-interactive mode. |
The values are: |
0 : Unrestricted |
-1 : Interactive only |
1 : Non-interactive only |
A script to generate skeletal files for a new command is included, it can be |
found in cmds/mknewcmd. To generate a new modular command named 'foo', which |
should also be reachable by typing 'f00', you would issue this command: |
./mknewcmd -n foo -a f00 -t module |
This generates all needed files and instructs you on how to include your new |
command in the build and make it accessible. By default, the command will be |
unrestricted. Builtin commands can be created by changing 'module' to |
'builtin' |
There are more options to mknewcmd, which allow you to specify the |
description, entry point, help entry point, or restriction. By default, names |
just follow the command such as cmd_foo(), help_cmd_foo(), 'The foo command', |
etc. If you want to see the options and explanations in detail, use |
./mknewcmd --help. |
When working with commands, keep in mind that only the main and help entry |
points need to be exposed. If commands share the same functions, put them |
where they are exposed to all commands, without the potential oops of those |
functions going away if the command is eliminated in favor of a stand alone |
external program. |
The util.c file is a great place to put those types of functions. |
Also, be careful with globals, option structures, etc. The compiler will |
generally tell you if you've made a mistake, however declaring: |
volatile int foo |
... in a command will allow for anything else to pick it up. Sometimes |
this could be desirable .. other times not. When communicating between |
builtins and the main system, try to use cliuser_t. The one exception |
for this is the cli_quit global, since everything may at some point |
need to check it. Modules should only communicate their return value. |
Symbolic constants that everything needs should go in the config.h file, |
however this is not the place to define shared macros. |
Making a program into a module |
============================== |
If you have some neat program that would be useful as a modular command, |
converting it is not very hard. The following steps should get you through |
the process easily (assuming your program is named 'foo'): |
1: Use mknewcmd to generate the skeletal files. |
2: Change your "usage()" command as shown: |
-- void usage(...) |
++ void * help_cmd_foo(unsigned int level) |
-- return; |
++ retrn CMD_VOID; |
'level' is either 0 or 1, indicating the level of help requested. |
If the help / usage function currently exits based on how it is |
called, you'll need to change it. |
3: Change the programs "main()" as shown: |
-- int main(int argc, char **argv) |
++ int * cmd_foo(char **argv) |
-- return 1; |
++ return CMD_FAILURE; |
-- return 0; |
++ return CMD_SUCCESS; |
If main() returns an int that is not 1 or 0 (e.g. 127), cast it as |
such: |
-- return 127; |
++ return (int *) 127; |
NOTE: _ONLY_ the main and help entry points need to return int * or |
void *, respectively. Also take note that argc has changed. The type |
for entry points may soon change. |
NOTE: If main is void, you'll need to change it and ensure that its |
expecting an array of arguments, even if they'll never be read or |
used. I.e.: |
-- void main(void) |
++ int * cmd_foo(char **argv) |
Similararly, do not try to return CMD_VOID within the modules main |
entry point. If somehow you escape the compiler yelling at you, you |
will surely see pretty blue and yellow fireworks once its reached. |
4: Don't expose more than the entry and help points: |
-- void my_function(int n) |
++ static void my_function(int n) |
5: Copy/paste to the stub generated by mknewcmd then add your files to the |
Makefile. Be sure to add any directories that you made to the SUBDIRS so |
that a 'make clean' will clean them. |
Provided that all functions that your calling are available in the |
userspace C library, your program should compile just fine and appear |
as a modular command. |
Overcoming userspace libc obstacles |
=================================== |
A quick glance through the util.c file will reveal functions like |
cli_strdup(), cli_strtok(), cli_strtok_r() and more. Those are functions |
that were missing from userspace libc when BDSH was born. Later, after |
porting what was needed from FBSD/NBSD, the real functions appeared in |
the userspace libc after being tested in their cli_* implementations. |
Those functions remain because they guarantee that bdsh will work even |
on systems that lack them. Additionally, more BDSH specific stuff can |
go into them, such as error handling and reporting when malloc() fails. |
You will also notice that FILE, fopen() (and all friends), ato*() and |
other common things might be missing. The HelenOS userspace C library is |
still very young, you are sure to run into something that you want/need |
which is missing. |
When that happens, you have three options: |
1 - Implement it internally in util.c , when its tested and stable send a |
patch to HelenOS asking for your function to be included in libc. This is |
the best option, as you not only improve BDSH .. but HelenOS as a whole. |
2 - Work around it. Not everyone can implement / port fopen() and all of |
its friends. Make open(), read(), write() (etc) work if at all possible. |
3 - Send an e-mail to the HelenOS development mailing list. Explain why you |
need the function and what its absence is holding up. |
If what you need is part of a library that is typically a shared object, try |
to implement a 'mini' version of it. Currently, all userspace applications |
are statically linked. Giving up creature comforts for size while avoiding |
temporary 'band aids' is never frowned upon. |
Most of all, don't get discouraged .. ask for some help prior to giving up |
if you just can't accomplish something with the limited means provided. |
Contributing |
============ |
I will take any well written patch that sanely improves or expands BDSH. Send |
me a patch against the trunk revision, or, if you like a Mercurial repository |
is also maintained at http://echoreply.us/hg/bdsh.hg and kept in sync with |
the trunk. |
Please be sure to follow the simple coding standards outlined at |
http://www.helenos.eu/cstyle (mostly just regarding formatting), test your |
changes and make sure your patch applies cleanly against the latest revision. |
All patches submitted must be your original code, or a derivative work of |
something licensed under the same 3 clause BSD license as BDSH. See LICENSE |
for more information. |
When sending patches, you agree that your work will be published under the |
same 3 clause BSD license as BDSH itself. Failure to ensure that anything |
you used is not under the same or less restrictive license could cause major |
issues for BDSH in the future .. please be sure. Also, please don't forget |
to add yourself in the AUTHORS file, as I am horrible about keeping such |
things up to date. |

This is a very brain dead shell. It needs some love, coffee or perhaps beer. |
Currently, you can't even really call it a shell, its more of a CLI that |
offers some shell like creature comforts. |
This was written in a hurry to provide some means of testing persistent file |
systems in HelenOS. It does its job, its nowhere near complete but it is |
actively developed. If your reading this, its likely that you're looking for |
some functionality that is not yet present. Prior to filing a bug report, |
please make sure that what you want is not on the list below. |
A list of things to do: |
----------------------- |
* rm: add support for recursively removing directories and files therein |
* Port an editor (vim?) |
* Finish cat / cp |
* Support basic redirection (i.e ls > foo.txt) |
* Expand wildcards (i.e. *.txt), don't worry about variables for now |
* Basic scripting |
* Hash previously found commands |
* Improve input, add history / etc (port libedit?) |
* Add wrappers for signal, sigaction to make ports to modules easier |
* Add 'echo' and 'printf' modules. |
Regarding POSIX: |
---------------- |
POSIX is a standard for Unix-like operating systems. HelenOS is (mostly) just |
a kernel at this point with a few userspace programs that facilitate testing |
of the kernel and file systems. |
HelenOS is not a Unix-like operating system. HelenOS is its own thing, a modern |
microkernel OS and many directions are not yet set. |
Please do not e-mail me to point out that modular implementations that resemble |
typical core utilities do not conform to some POSIX standard, these are temporary |
and serve the useful purpose of testing persistent file systems. |
Contributing: |
------------- |
If you feel like doing any of the above to-do items, I am echo@echoreply.us. Please |
e-mail me and let me know your working on something so that I do not unwittingly |
duplicate your efforts. You can also e-mail the HelenOS list directly: |

Written by Tim Post <echo@echoreply.us> to serve as a primitive shell |
for HelenOS, or as a template to make a command line interface that |
offers shell like creature comforts. |
This program was mostly written from scratch, some existing code was |
used from other various free software projects: |
* Based on the HelenOS testing sub-system written by Martin Decky |
* cli_strtok() and cli_strtok_r() (util.c) were adapted from the FreeBSD |
strtok() and strtok_r() functions written by Wes Peters. |
* read_line() (input.c) was written by Jiri Svoboda |
