Retro is a modern, pragmatic Forth drawing influences from many
|
|
sources. It's clean, elegant, tiny, and easy to grasp and adapt
|
|
to various uses.
|
|
|
|
Features:
|
|
|
|
- Open Source (ISC License)
|
|
- Portable (runs on a MISC-style virtual machine)
|
|
- Small source & binaries
|
|
- Builds into a single, self contained binary for easy deployment
|
|
- Sources in literate format, using a Markdown variant
|
|
|
|
## Quick Start
|
|
|
|
For most systems (FreeBSD, NetBSD, OpenBSD, macOS, Linux):
|
|
|
|
make
|
|
|
|
You will need a standard C compiler and `make`.
|
|
|
|
## Executables
|
|
|
|
Binaries will be placed in the `bin` directory.
|
|
|
|
The primary executable is `retro`. This is used for running the
|
|
examples and the Atua (gopher) & Casket (http) servers that
|
|
power forthworks.com.
|
|
|
|
The `retro` executable embeds the image into the binary, making
|
|
it trivial to copy and deploy.
|
|
|
|
This interface layer also extends the language with many new
|
|
words and vocabularies, adds scripting, file i/o, floating point,
|
|
and more.
|
|
|
|
The `retro` executable can handle a variety of command line
|
|
arguments which are covered in the manpage, but the most common
|
|
ones are:
|
|
|
|
retro
|
|
|
|
Starts the *listener*, a basic REPL for interactive use.
|
|
|
|
retro filename
|
|
|
|
This will run the code in the specified file, then exit. This
|
|
is also used to run programs as shell-type scripts using a
|
|
header line like `#!/usr/bin/env retro`.
|
|
|
|
retro -i -f filename
|
|
|
|
This will run the code in the specified file, then start the
|
|
listener.
|
|
|
|
## Literate Sources
|
|
|
|
Source files for use with `retro` are written with code in
|
|
fenced blocks:
|
|
|
|
commentary here
|
|
|
|
~~~
|
|
code here
|
|
~~~
|
|
|
|
Anything outside the fenced blocks will be ignored.
|
|
|
|
## Documentation
|
|
|
|
The primary documentation is in RETRO-Book.md (and the formatted
|
|
epub.) Additional notes can be found in the `doc` directory.
|
|
|
|
## Alternative Implementations
|
|
|
|
In addition to the C and Python implementations, this source
|
|
tree includes additional implementations in C#, Nim, JavaScript,
|
|
and Pascal. These are not as well tested or as feature complete
|
|
as the main implementations, but are provided for your use if
|
|
the standard implementations will not suffice.
|
|
|
|
## Patreon
|
|
|
|
I have a Patreon at https://www.patreon.com/_crc for those that
|
|
want to financially support development. All funds raised via
|
|
Pateron are put into development related expenses (server expenses,
|
|
app store fees, hardware).
