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.

## Quick Start
|
|
|
|
|
|
2019-01-03 15:06:15 +01:00
|
|
|
For most systems (FreeBSD, NetBSD, OpenBSD, macOS, Linux):
|
2017-10-16 18:09:39 +02:00
|
|
|
|
2018-04-18 17:42:23 +02:00

|
make
|
2017-10-20 03:54:31 +02:00
|
|
|
|
2019-05-01 16:02:34 +02:00
|
|
|
You will need a standard C compiler and `make`.

|
|
## Executables
|
|
|
|
|
|
|
|
|
|
Binaries will be placed in the `bin` directory.
|
|
|
|
|
|
2018-11-04 22:34:56 +01:00
|
|
|
The primary executable is `retro`. This is used for running the
|
|
|
|
|
examples and the Atua (gopher) & Casket (http) servers that
|
|
|
|
|
power forthworks.com.
|
2018-05-10 02:54:05 +02:00
|
|
|
|
2018-11-09 04:11:58 +01:00
|
|
|
The `retro` executable embeds the image into the binary, making
|
|
|
|
|
it trivial to copy and deploy.
|
2018-05-10 02:54:05 +02:00
|
|
|
|
2018-11-09 04:11:58 +01:00
|
|
|
This interface layer also extends the language with many new
|
|
|
|
|
words and vocabularies, adds scripting, file i/o, gopher, and
|
2018-05-10 02:54:05 +02:00
|
|
|
floating point math support.
|
|
|
|
|
|
2018-11-09 04:11:58 +01:00
|
|
|
The `retro` executable can handle a variety of command line
|
|
|
|
|
arguments:
|
|
|
|
|
|
|
|
|
|
retro -i
|
|
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
retro -h
|
|
|
|
|
|
|
|
|
|
Displays a summary of the command line arguments.
|
|
|
|
|
|
|
|
|
|
Source files for use with `retro` are written with code in
|
|
|
|
|
fenced blocks:

## Documentation
|
|
|
|
|
|
|
|
|
|
The primary documentation is in RETRO-Book.md (and the formatted
|
|
|
|
|
RETRO-Book.html.) Additional notes can be found in the `doc`
|
|
|
|
|
directory.

## Commercial Versions
|
|
|
|

|
|
|
I provide versions of RETRO for iOS and macOS via the Apple app
|
|
|
|
|
stores. These use a custom, dual pane editor-based environment
|
|
|
|
|
and some platform specific words and extensions. They do use the
|
2018-11-04 22:34:56 +01:00
|
|
|
same image and virtual machine as `retro`, `retro-repl`, etc.

|
|
implementations will not suffice.
