|
In addition to the C implementation, there are a few other
|
|
interfaces that can be built.
|
|
<br/><br/>
|
|
<span class="h2">Requirements</span>
|
|
<br/><br/>
|
|
• c compiler (tested: clang, tcc, gcc)<br/>
|
|
• make<br/>
|
|
• standard unix shell<br/>
|
|
<br/><br/>
|
|
<span class="h2">retro-repl</span>
|
|
<br/><br/>
|
|
A basic interactive system can be built by using:
|
|
<br/><br/>
|
|
<tt class='indentedcode'>make bin/retro-repl</tt>
|
|
<br/><br/>
|
|
This requires a copy of <span class="tt">ngaImage</span> to be in the current
|
|
directory.
|
|
<br/><br/>
|
|
<span class="h2">Barebones</span>
|
|
<br/><br/>
|
|
This is a minimal version of the <span class="tt">retro-repl</span>. It keeps the C
|
|
portion as short as possible, making it a useful starting point
|
|
for new interfaces.
|
|
<br/><br/>
|
|
To build:
|
|
<br/><br/>
|
|
<tt class='indentedcode'>make bin/retro-barebones</tt>
|
|
<br/><br/>
|
|
<span class="h2">retro-compiler</span>
|
|
<br/><br/>
|
|
This is a turnkey compiler. It can compile a new executable
|
|
bundling a Retro VM and image.
|
|
<br/><br/>
|
|
Requirements:
|
|
<br/><br/>
|
|
• BSD or Linux<br/>
|
|
• objcopy in $PATH<br/>
|
|
<br/><br/>
|
|
To build:
|
|
<br/><br/>
|
|
<tt class='indentedcode'>make bin/retro-compiler</tt>
|
|
<br/><br/>
|
|
Example use:
|
|
<br/><br/>
|
|
1. Given a source file like "Hello.forth":
|
|
<br/><br/>
|
|
<tt class='indentedcode'>~~~</tt>
|
|
<tt class='indentedcode'>:hello 'hello_world! s:put nl ;</tt>
|
|
<tt class='indentedcode'>~~~</tt>
|
|
<br/><br/>
|
|
2. Use:
|
|
<br/><br/>
|
|
<tt class='indentedcode'>./bin/retro-compiler Hello.forth hello</tt>
|
|
<br/><br/>
|
|
The first argument is the source file, the second is the
|
|
word to run on startup.
|
|
<br/><br/>
|
|
3. Run the generated <span class="tt">a.out</span>
|
|
<br/><br/>
|
|
Limits:
|
|
<br/><br/>
|
|
This only supports the core words ('all' interface) and the
|
|
file i/o words. Support for other I/O extensions will be
|
|
added in the future.
|
|
<br/><br/>
|
|
<span class="h2">Pascal</span>
|
|
<br/><br/>
|
|
There is a Pascal version of <span class="tt">retro-repl</span>.
|
|
<br/><br/>
|
|
Dependencies:
|
|
<br/><br/>
|
|
• freepascal<br/>
|
|
<br/><br/>
|
|
Building:
|
|
<br/><br/>
|
|
<tt class='indentedcode'>cd vm/nga-pascal</tt>
|
|
<tt class='indentedcode'>fpc listener.lpr</tt>
|
|
<br/><br/>
|
|
This will require a copy of the <span class="tt">ngaImage</span> in the
|
|
current directory.
|
|
<br/><br/>
|
|
<br/><br/>
|
|
This is an implementation of <span class="tt">retro-repl</span> in Python. As
|
|
with <span class="tt">retro-repl</span> it requires the <span class="tt">ngaImage</span> in the current
|
|
directory when starting.
|
|
<br/><br/>
|
|
<br/><br/>
|
|
This is an implementation of <span class="tt">retro-repl</span> in C#. As with
|
|
<span class="tt">retro-repl</span> it requires the <span class="tt">ngaImage</span> in the current
|
|
directory when starting.
|
|
<br/><br/>
|
|
Building:
|
|
<br/><br/>
|
|
<tt class='indentedcode'>cd vm\nga-csharp</tt>
|
|
<tt class='indentedcode'>csc retro.cs</tt>
|
|
<br/><br/>
|
|
You'll need to make sure your path has the CSC.EXE in it,
|
|
or provide a full path to it. Something like this should
|
|
reveal the path to use:
|
|
<br/><br/>
|
|
<tt class='indentedcode'>dir /s %WINDIR%\CSC.EXE</tt>
|
|
<br/><br/>
|
|
I've only tested building this using Microsoft's .NET tools.
|
|
It should also build and run under Mono.
