# Contributor Covenant Code of Conduct
## Our Pledge
We as members, contributors, and leaders pledge to make participation in our
community a harassment-free experience for everyone, regardless of age, body
size, visible or invisible disability, ethnicity, sex characteristics, gender
identity and expression, level of experience, education, socio-economic status,
nationality, personal appearance, race, religion, or sexual identity
and orientation.
We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.
## Our Standards
Examples of behavior that contributes to a positive environment for our
community include:
* Demonstrating empathy and kindness toward other people
* Being respectful of differing opinions, viewpoints, and experiences
* Giving and gracefully accepting constructive feedback
* Accepting responsibility and apologizing to those affected by our mistakes,
and learning from the experience
* Focusing on what is best not just for us as individuals, but for the
overall community
Examples of unacceptable behavior include:
* The use of sexualized language or imagery, and sexual attention or
advances of any kind
* Trolling, insulting or derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or email
address, without their explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Enforcement Responsibilities
Community leaders are responsible for clarifying and enforcing our standards of
acceptable behavior and will take appropriate and fair corrective action in
response to any behavior that they deem inappropriate, threatening, offensive,
or harmful.
Community leaders have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions that are
not aligned to this Code of Conduct, and will communicate reasons for moderation
decisions when appropriate.
## Scope
This Code of Conduct applies within all community spaces, and also applies when
an individual is officially representing the community in public spaces.
Examples of representing our community include using an official e-mail address,
posting via an official social media account, or acting as an appointed
representative at an online or offline event.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported to the community leaders responsible for enforcement at
interval1066@gmail.com.
All complaints will be reviewed and investigated promptly and fairly.
All community leaders are obligated to respect the privacy and security of the
reporter of any incident.
## Enforcement Guidelines
Community leaders will follow these Community Impact Guidelines in determining
the consequences for any action they deem in violation of this Code of Conduct:
### 1. Correction
**Community Impact**: Use of inappropriate language or other behavior deemed
unprofessional or unwelcome in the community.
**Consequence**: A private, written warning from community leaders, providing
clarity around the nature of the violation and an explanation of why the
behavior was inappropriate. A public apology may be requested.
### 2. Warning
**Community Impact**: A violation through a single incident or series
of actions.
**Consequence**: A warning with consequences for continued behavior. No
interaction with the people involved, including unsolicited interaction with
those enforcing the Code of Conduct, for a specified period of time. This
includes avoiding interactions in community spaces as well as external channels
like social media. Violating these terms may lead to a temporary or
permanent ban.
### 3. Temporary Ban
**Community Impact**: A serious violation of community standards, including
sustained inappropriate behavior.
**Consequence**: A temporary ban from any sort of interaction or public
communication with the community for a specified period of time. No public or
private interaction with the people involved, including unsolicited interaction
with those enforcing the Code of Conduct, is allowed during this period.
Violating these terms may lead to a permanent ban.
### 4. Permanent Ban
**Community Impact**: Demonstrating a pattern of violation of community
standards, including sustained inappropriate behavior, harassment of an
individual, or aggression toward or disparagement of classes of individuals.
**Consequence**: A permanent ban from any sort of public interaction within
the community.

The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software are designed to take away your

The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. License is intended to guarantee your freedom to share and change free

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.

Foundation's software and to any other program whose authors commit to

(Some other Free Software Foundation software is covered by

You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. your programs, too.
Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. When we speak of free software, we are referring to freedom, not

Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free.

To “propagate” a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy.

An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.

The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A “Major Component”, in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The precise terms and conditions for copying, distribution and
modification follow.
The “Corresponding Source” for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.

You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. that is to say, a work containing the Program or a portion of it,

3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. Activities other than copying, distribution and modification are not

When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. running the Program is not restricted, and the output from the Program

You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. Whether that is true depends on what the Program does.
You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you

a) The work must carry prominent notices stating that you modified it, and giving a relevant date. and give any other recipients of the Program a copy of this License
along with the Program.
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to “keep intact all notices”.
You may charge a fee for the physical act of transferring a copy, and
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. you may at your option offer warranty protection in exchange for a fee.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. 2. You may modify your copy or copies of the Program or any portion

A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an “aggregate” if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.

part thereof, to be licensed as a whole at no charge to all third
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. parties under the terms of this License.
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. c) If the modified program normally reads commands interactively

A “User Product” is either (1) a “consumer product”, which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, “normally used” refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product.

If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
These requirements apply to the modified work as a whole. If
The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed.

“Additional permissions” are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. on the Program, the distribution of the whole must be on the terms of

All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. a) Accompany it with the complete corresponding machine-readable

You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.

If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. “Knowingly relying” means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. 4.

If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. otherwise to copy, modify, sublicense or distribute the Program is

A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.

If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to

Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

# interp
Simple command interpeter for embedded projects in C. I needed to re-write a very badly written command shell for an internet appliance once. Too bad that company elected not to use it; "would cost to much to replace." Bad idea and I hope you're not using that product, it was a security nightmare. Also, for various technical reasons, this had to be written in linear C, not C++. Which is not really a bad way to go with some embedded platforms.
Although by no means useful as is, the design is really quite modular and loosely coupled; adding new commands to this is a simple matter of adding them to "commands" and "table" static members of the main module<sup>1</sup>, then adding their definitions to either the "foo1" translation unit or a completely new one, just add the new files with your functionality defined in them.
The "huff" module is a simple huffman encryption C implementation you can use to encrypt plain text, like the message of the day included example command. Use it to do just that or maybe a list of passwords or whatever, or completly remove it and make the app even smaller. Warning: its just that; a simple huffman encoding implementaion. Please use AES or something like that for really sensitive data. Its meant soley as a way to make non-critical data readable only through the app.
Action is a first match, arbitrary length thing; q, qu, and qui will all "quit" the interpreter, but quib will not. The logic that implements this is tiny (pretty terse pointer magic) and all contained in the main module<sup>1</sup> (but not in the main function, there's like two or three static functions in the main module that handle all this. It shouldn't be a huge climb to follow. That same magic extends to commands as parameters to the help module; simply typing "h a" will return info on the arp command, simply being entered into the "commands" and "table" tables is snough to have the application treat them like any other command.
As is the code compiles down to under 35K bytes<sup>3</sup>, filled out with some actually useful commands, stripped release, and an embedded clib, I figure you can have a board that can do things via this interpreter for well under 100KB or possibly less if you really watch your memory usage.
Builds its own command menu automgically, no need to update that. Detailed descriptions will need updating in extra/interp.hlp however. Rename to your actual application name and place in the $USER home directory.
Autoconf automatically provides an "install" command but there's no point in installing this. I'm going to remove the autoconf directive. You are welcome to use the autoconf install command if you want but its really kind of pointless. I would add that in your own finished package that uses this code.
As well as typical scripts for autotools there's a qtcreator project file and a visual studio 2022 project configuration just for fun.
Builds an ARMhf 32 bit target using the generic makefile in the linux subdirectory as long as you have the GCC ARMhf compiler installed on your system,
can probably target other platforms using GCC or LLVM.
To initiate an autotools build just run autogen.sh and follow the instructions, make sure that the execute bit is set on the automake and clean scripts. To build using the qtcreator project file load the project and select your build kit of choice. To build on Windows you'll need to reconfigure the project for your Win SDK, obviously. I'm on visual studio 2022, so you may need to create a project for your version and add the source modules manually. For visual studio code I have no idea, I rarely use that ide. For eclipse? Lift the voodoo curse off yourself and stop using it, you know that thing was originally written by IBM??
autoclean.sh should reset the entire source directory to the "ground state." See "newcmds.md" for instruction on adding commands to the interpreter. Take special note
of the user context struct, its key for makeing changes to the shell's environment without needing to re-start it.
Again, and probably can't be stressed enough; this project is a "starter" project for your own command line processor engine or shell utiity; the included commands in the foo1 source are just examples; all of them need to be replaced with your required functionality and the extra/interp.help updated with actual descriptions of your new commands. MAKE INSTALL will do NOTHING USEFUL, but you can use it if for some reason you must. Never the less this is fully functioning code (the foo commands don't do anything though, not really) I simply consider it bad form to provide broken example code. That said, there maybe be some "slightly" broken code here and there. Pleaase write me about it or submit your own patch if you like.
Depends on libconfig, barely. Can be easily removed if needed.
7/12/2024 Fixed flaw with the help code.
---
1. The code now counts the number of members in the table static global member automatically, no need for this constant anymore. Also, the "commands" & "table" structs have been moved to include/parser.h.<br>
2. This has been eliminated in subsequent versions.
3. Under 25K on windows.
9/11/2024 Uncovered some serious issues
---
Turns out libconfig sucks. You can't put arbitrary characters in the ini files, it either needs to have legitmate alphanumeric characters or no file. If it encounters, say stars or hashbangs it spews core. Unacceptable. So I'm going back to my original idea of writing my own ini parser. When I can. Really busy right now.
10/26/2024 Removed the libconfig dependancy

Got the above done.

### Adding New Commands to the Interpreter
<p>The code consists of intrinsic commands and add-on commands. Intrinsic commands shouldn't be modified
or expanded.</p>
<p>Add-on commands are all the other commands you can see in the "foo1" source file. Add-ons can be added to
those existing sources, added to an entirely new translation unit, to a static library or a shared lib, whatever
makes the most sense for your application. You're also welcome to remove all of those commands and add your own, of course.</p>
#### Adding a Log Level Command
<p>In this example, we'll add a new command called `loglevel` that will set the logging level of the of the
interpreter. There are lots of descisions to make in developing a loggng facility to an application; mostly
its scope, where it'll be written and its persistence, but since we won't actually implement a working logging
facility we'll just worry about adding the command to the interpreter.</p>
<p>Let's add the command "loglevel" with an integer parameter 0-4. 0 will mean logging off, and 4 is the highest
level of verbosity:</p>
1. Add our new command "loglevel" to the "commands" double array in the "parser.h" file. The question mark must be the last command in the array, and help must always be first:
``` c
const char* commands[] = { "dummy",
"help",
"aaa",
"access-lists",
"amplifiers",
"app",
<...>
"loglevel",
"?" };
```
2. Add a "loglevel" token to the "table" double array. Note, this is just an index token, not a string.
Importance is its place in the table, not its value:
``` c
int (*table[])() = {
dummy, help, aaa, alist, amp, app, arp, badl, batch, bert,
help, motd, prompt, quit, date, list, time2, loglevel
};
```
3. For statically linked commands define the function(s) for your new command in either foo1.c or add a new source file to the project. Add the new function prototypes to the appropriate header files. Use a pointer to the command invocation for access to parameters and delimeter processing; for example; if you want to use posix-style parameter marking ('-' & '--', and etc) define that in your new translation unit and pass all paramters through it before routing to the actual command definition. Look to the command examples in foo1.c for examples.
4. Add a useful description of the new command the ./extra/help file.
No modification of the parser code should be required for the UTF-8 charcter set-based projects. A list of all the commands is printed out when the user enters "help" or "?" and generated automtically from the available data. Command descriptions must be entered into the text file in the extra directory.
The "dummy" command is nessessary for now, obviously an index is off, I'll be getting rid of that when I find the error.
If you do see a problem a report would be appreciated. interval1066@gmail.com.

# Building interp on Windows
I configured this project with Visual Studio 2022, I hope you have few problems, I've been noticing
over the last few years Microsoft has been pretty good about making visual studio projects back rev
compatible, if you have problems would love to hear about them, send reports to
interval1066@gmail.com.
If you haven't done it yet configure vcpkg to work with vs2022 or your preferred version of VS, I
understand versions after 2017 can do this with varying degrees of success.
Follow the instructions here for installation and configuration of vcpckg:
https://devblogs.microsoft.com/cppblog/vcpkg-is-now-included-with-visual-studio/
That should be all you need to do. In visual studio look at the include list in filesys.h; line
7 should be the include for libconfig.h. If its not underlined then the project is probably
ready to build.
(10/17/2024) All dependancies on libconfig have been removed.
