Sphinx—as seen at UPEW!

I got out of my comfort zone and gave a presentation at UPEW on my latest project. It's yet another Spin compiler I'm afraid, but with a bit of a twist: www.sphinxcompiler.com

The website is still a work in progress, but then again so is the software, really. Proceed at your own risk.

    Oh my god. Wow!

    I have no keyboard around here, will it be easy for me to modify to use a serial terminal just to check it out?

    Fantastic news Michael jumpin.gif

    As soon as time permits, I am definately going to have to dust off my version of Chip's spin interpreter and modify it to use external sram yeah.gif

    This is great! You gave a very nice demonstration mpark! I didn't think it was possible... I was going to look into doing an onboard BASIC compiler, but this is much better...

    I bet one could even add a debugger that would show values of certian HUB RAM variables somewhere...

    Really nice of you to make it MIT license.

    And his presentation was Propeller only. (and that alone was very cool) I loved the "Prop Point" joke. Mike has this great delivery where he just puts it out there and everybody starts grinning. Bonus points for interacting with the audience!

    @mpark Your presentation reminded me of how Larry Lessig normally does things.

    Thanks all! Sorry about the unfinished documentation. I'll try to finish it up or at least flesh it out when I get back home in a couple of days.

    @heater: Depends on how you define "easy". I'm sure it's possible, but it kinda defeats the whole spirit of the thing. Just buy a keyboard, man!

    @jazzed: Sorry I missed you at the expo. I wanted to put as many faces to handles as I could.

    @potatohead: I've never seen Larry Lessig, but I'll take your comment as a compliment.

    @UPEW attendees: A real pleasure to meet you in person. What a great bunch!

    As Potatohead mentioned, I ran my presentation off a Propeller, specifically a Hybrid. I wish I'd taken a second to give a shout-out to Coley for a great board. Belatedly: Thank you Coley!

    If you try out Sphinx, I think you'll soon find that Ed is just not up to the task of editing Spin files, so everyone go pester CassLan to get his PrEditor done.

    Thanks and your are most welcome, words of encouragement like that is all I need!

    I'm at works at the moment but rest assured I will be firing up my Hybrid and trying this as soon as I get in...

    How exciting..... smilewinkgrin.gif

    @Mpark It's a compliment.

    I'll second the recommendation for the HYBRID board. It's my favorite and it is rock solid. Highly recommended.

    Considering the 100Mhz XTAL upgrade to it this week!

    BTW, I was at the Expo, and in my mind Sphinx is best of show.

    Now to get the source and see if we can't make an interactive Spin environment
    (type in a spin expression and see what happens immediately!). That would
    make it fun for people to play with the counters and stuff.

    Unbelievably cool !!!

    It was great to meet you and your wife - I am looking forward to watching the video so I can catch all of it as I missed large portions explaining Morpheus to people coming to my table (I was very excited to spill the beans at last!)

    Largos will support your compiler.

    Fantastic Michael - still jumpin.gif for joy cool.gif

    I will have to modify your code for the TriBlade and the RamBlade as follows (but easy to do as soon as I can find the time)
    • SD card pins are not contiguous and on the TriBlade and -CS is on a latch
    • The terminal (keyboard and video) are on another prop, so FDX has to communicate to the other prop

    Do you have a version (driver)·that runs to the PC (instead of keyboard and video) like heater did in ZiCog ? Before I get comments... yes, I know this defeats the intended purpose. I often do this when I cannot get access to the VGA screen (it doubles as our TV on the boat). If not, then I will have a go at this.

    I will also have to get·sram working as a SD FAT16 disk. Faster compiles tongue.gif

    I can see lots of interesting work to do yeah.gif

    Wow
    .. this is not only the first "on chip" compiler, it is also the first open source Spin compiler !!!!
    And with so little limitations, I never considered this as possible.

    Hi all. Finally back home after a leisurely road trip. A few things:
    1. The source is open, but it's also a mess. If you can figure it out, please feel free to take it in whatever directions you like.
    2. If you experience strange errors running Sphinx, try reformatting the SD card. A cop-out, I know, but remarkably effective.
    3. I will work on the documentation on the website. Please post or email any questions or suggestions. I could use them to guide me; otherwise I'll just write whatever.

    I've been working on a new version of fsrw (with lonesock) so no time to make a REPL (read-eval-print loop) based on this.

    Maybe someone else would like to take up this challenge?

    Even something that only read-eval-prints a single simple expression would be extremely cool and useful.

    Dude,
    This is an awesome piece of work.
    I'm working hard on Preditor to get it done to be used inconjunction with this.

    And I'm happy to say that whats done of it so far compiles and runs off Sphinx with no problems!, And it uses FSRW, KB, FullDuplexSerial..etc all just as it does if compiled with PropTool.

    Way to go !!!!

    mpark- Any chance of getting some simple scripting support? something similar to .BAT functionality...just a few lines inside of a textfile to be run from the command line? Cause then we could just have that file compile everything backwards for us then link it then run it...pretty please? : )

    Also,

    Has anyone started an "OBEX" for .SOB files?

    I've got a server with 160gigs & upload script if someone hasn't
    started that direction yet.

    @OBC,

    (my 2 cents...) It sounds like a good idea, but would then be yet another (offsite)·place to check for updates.

    It·would·seem better to just post a pre-compiled .SOB object with·submissions to the OBEX.· That way, those that are using Sphinx (or the inevitable derivitives) could use the .SOB objects, and others could compile the full code.·

    Scripts would be nice but I don't know how to implement them. Keep in mind that Sphinx doesn't have a real "operating system" (it kinda looks like it does, but it's faking it). I should look into how a real OS does it and see if I can fake it in Sphinx. Largos might be ready before I get to it, though.

    Rick, how many files are you compiling each time? You only have to compile the ones that have changed.

    About the "SOBEX" idea: Chip told me that the Propeller Tool was originally going to support SOB-like files, but they decided against it to encourage people to publish source code. I don't really think there's a need for a SOBEX. Folks can just get source from OBEX and compile it to .sob themselves, either with Sphinx or, if it's beyond Sphinx's capabilities, with Homespun. Or they can publish both source and SOB, per Trodoss's compromise, but source code should be the primary medium of exchange.
