HomeSpun Compiler Open Source

As I need a spin compiler that can be easily cuctomized for the up coming Propbasic Studio I have contacted mpark about releasing the source for his HomeSpun compiler.

mpark has generously agreed to do so and has released it under the MIT license.

Here is a Visual Studio 2012 project using the released source code.

I have made a minor change in the dissembler module but otherwise the code is as before. Now Build Version 0.3.2.

The Zip contains the VS2012 project as well as Debug and Release binaries.

Cheers

    Wow, way to go mpark. Thank you.

    There is some kind of irony here, considering our recent debate re. the merits of open and closed source.

    Fully aware of the irony when I created the thread :)

    A point I made that I think was lost in that thread was you guys needed to concentrate on the steak and not the peas, QED the compilers not the IDE.

    Cheers.

    Fantastic news. Way to go Mark!

    FWIW, Catalina uses a modified version of homespun (not sure what the mods are).

    Thanks Michael (mpark). Thanks to you we can move ahead with PropBasic Studio.

    Is Homespun required for PropBASIC Studio? Wouldn't it be better to use Roy's compiler since that will eventually be the basis for a P2 version of Spin/PASM. Seems like it would make more sense to use that for any new work.

    I guess the key word in your quote is "eventually".

    However the Propbasic compiler output does not currently work with Roy's spin compiler, I do not recall the reason at the moment so perhaps Bean can elaborate.

    Despite mpark's self depreciating comments to the contrary the homespun compiler is a solid performer that has been around for several years now.

    I or others are quite capable of updating or changing it for the P2, the same undertaking will be required for Roy's compiler.

    As I doubt that there will be production release silicon for the P2 this year, this is somewhat academic.

    Cheers.

    Side Note: I would like to see the homespun compiler project posted to a code repository somewhere, so if some would like to do this and maintain it I am willing to provide commits to the changes I will be doing to it..

    Cheers.
    I guess the difference is that Roy's compiler (called OpenSpin I think) is officially supported by Parallax. It would be good to know what is preventing it from working with PropBASIC. I'm sure that problem can be addressed.

    The spin compiler must support the @@@ operator.

    Thanks Bean! I'm sorry to say that I don't even know what that operator does. Maybe Roy will comment on whether he can add that to OpenSpin.

    Great! Thanks! Will the Homespun compiler run on the Mac or Linux?

    If I recall it worked with mono on both, refer to the original thread for more info:

    David,

    @@@ does what you expect @ or @@ to do but gets it right. That is is it gives the physical, actual, real HUB address of something. It works when initializing data in DAT sections, unlike the others. It gives the same result no matter where you use it, unlike @.

    HomeSpun works on Linux under the mono runtime. It even works on Raspberry Pi and other ARM machines.

    Thank you again mpark. Fantastic.

    Thanks for the explanation. In other words, @@@ "sets the working bit"! I suppose @ and @@ must have some uses or they wouldn't be there though.

    If that is the case then ProBasic Studio should run on those platforms as well.

    The problem I had with mono is with the serial port. Maybe it has been fixed, but last I checked it only ran in polled mode. MS.net serial port is event driven of course and that led me into a false sense of having excellent multi-platform support. That's why I started using Qt.

    The workaround is to run on another thread which is a blocking read, similar to sockets programming.

    It builds. It runs. On my Debian 7.0 PC here at least. Thanks again Michael.

    I have take the liberty of creating a git repository of the content of Batang's VS2012 project posted above here:
    https://github.com/ZiCog/HomeSpun

    I don't have any plans to tinker with that code. It's just there. I only added a README file with attributions, links to documantation and build instructions for Debian.

    Batang, I have used HomeSpun on ARM Cortex A8 based boards running Debian and Linaro. Can't remember if I tried the Raspberry Pi. Wait a minute...

    Yay, HomeSpun runs on the Raspberry Pi.

    I updated the github readme with a note about what you need to install to run it on the raspi.

    I think Batang already put HomeSpun on Google Code. Is it going to live in two places at the same time?

    Ah, some how I missed that little news.

    Not to worry, it's a fork, I'm most likely not going to make any changes. I'm a github man and prefere git to subversion anyway. I'll add a link in the README directing any passers by to Batang's repo.

    I like git better too but subversion was selected for propgcc so I've kind of gotten used to using it.

    The problem is now I find myself all the time having to run between git, svn and hg, remebering how to drive them all is a pain.

    Yeah, remembering which command goes with which system is a pain. Sorry, I was wrong about propgcc. It's using Mercurial (hg) not Subversion.

    @@@ is on the list to be supported by OpenSpin.
