# Contributing
|
|
|
|
RETRO is an open-source project, but I am opinionated, and as I am
|
|
developing this primarily for my use, I may be picky when it comes
|
|
to adding changes to the core language.
|
|
|
|
I use Fossil to manage the RETRO source, but I do not accept pushes
|
|
to this directly. Patches or updated files can be emailed to
|
|
crc@forthworks.com. I will review and merge them manually.
|
|
|
|
## Interfaces
|
|
|
|
When making changes, I'm most open to extensions as part of the RRE
|
|
interface. (interfaces/rre.c, interfaces/rre.forth).
|
|
|
|
New interfaces are welcome. If they require more than 1-2 files, or
|
|
specific build systems (apart from BSD compatible `make` or `bin/sh`
|
|
scripts), please keep them in a separate subdirectory.
|
|
|
|
I'm not planning to accept new I/O or extensions to the basic REPL
|
|
(interfaces/repl.c) as this serves as a template for starting new
|
|
interfaces or implementations.
|
|
|
|
Changes or additions to the provided words must be documented in the
|
|
glossary (words.tsv).
|
|
|
|
## Kernel
|
|
|
|
The kernel (literate/Rx.md) is basically done. I'm still making small
|
|
changes in terms of tuning size/performance, but will not merge any
|
|
alterations to this apart from bug fixes currently.
|
|
|
|
## Standard Library
|
|
|
|
I may accept additions to the standard library. Words requiring any
|
|
I/O other than `putc` will not be accepted in the standard library.
|
|
|
|
Changes to the words must be documented in the glossary (words.tsv).
|
|
|
|
## Examples
|
|
|
|
I'm quite willing to add new examples or changes / improvements to
|
|
existing ones.
|
|
|
|
## Legal
|
|
|
|
All contributions to the main sources (existing interfaces, kernel,
|
|
standard library) must be public domain or under the ISC license
|
|
(see LICENSE.md). Please add the appropriate copyright notices to
|
|
the LICENSE and/or source files.
|
|
|
|
New examples or tools can be under similar licenses. Include the
|
|
copyright and license text in the sources.
|
|
|
|
I will not accept contributions under the GPL, LGPL, AGPL, or other
|
|
licenses that are too long to reasonably embed in a source file.
|
|
|
|
## Building
|
|
|
|
I do builds under GCC and CLANG on FreeBSD, NetBSD, Linux, macOS,
|
|
and Haiku. I build RRE for Windows using TCC on a Windows box.
|
|
Changes to the source must build cleanly on all test systems.
|
|
|
|
Note that Haiku uses GCC 2.95.3 for backwards compatibility with
|
|
BeOS R5 so sources must compile on this as well as modern compilers.
