1. Asking for help with Phix program under Linux

I do not have a Linux machine, have no experience with Linux, but still would like to make a Phix program I’ve written for Windows available to Linux users, too — so, in case that anyone here might be willing to help …?

The program is a calculator that runs in a console window, hypatia-rpn.net

In theory, the code should work with Linux, but lacking Linux I can neither test it, nor compile it. If you want to help, please see hypatia-rpn.net/linux.htm — if it indeed works, it shouldn’t take more than 15 minutes to test it. If it doesn’t work, of course … well, but maybe it does? Just answering a few of the questions would be helpful!

Also: if it works (sorry, I really have no experience with Linux), will the compiled executable run on all Linux systems?

Thank you! Robert

Thank you for your reply! I know about virtual machines, but I'd have to put in a lot of effort and learn a lot about Linux to get to the point where I can set up Phix and test something and understand why it may not work, or how far I can trust it if it does.

For the online interpreter I'm afraid the program is too large, it's split into several files, and I see no way to upload them. Also, it would't give me an executable, and wouldn't tell me how it behaves on a "real" system. And with AWS, I'd still need to learn a lot about Linux, which I'll never need for anything else, and honestly, I don't want to pay Amazon to be able to test something I'm giving away for free.

So, I still hope for someone who already has Phix on a Linux machine, to be interested enough to spend maybe 15 minutes to be able to tell me if it works - but, yes, I know I should be Linux literate, I can only apologize for being not.

That's a good question - once compiled on an older version, would it run on new versions?

I'm willing to give it a try this evening...

/home/irv/phix/builtins/pscreen.e:144 in procedure initI() 
attempt to divide by 0 

Oh dear, there's nothing particularly magical about that, just massive big chunks of completely missing code.
(Does anyone have any ideas for implementing video_config() and friends on Linux??)

Anyway, I renamed trim() as trimm() in 9 places, you may or may not have to do the same:

hypatia\source\hy-lib.e:329  li = trim(li[1..$-1]) 
hypatia\source\hy-lib.e:439    in = trim(in) 
hypatia\source\hy.exw:176   t = trim(t) 
hypatia\source\hy.exw:322   rline = trim(rline) 
hypatia\source\hy.exw:438   cline = trim(cline) 
hypatia\source\hy.exw:473  line = trim(line) 
hypatia\source\rslib42.e:18 -- function trim(object s) 
hypatia\source\rslib42.e:95 global function trimm(object s) 
hypatia\source\rslib42.e:109            s[j] = trim(s[j]) 

to work around video_config() being completely absent on linux, I changed hypatia\source\rslib42.e lines 20..32:

--  object scrn                      -- for calling video_config() 
--  scrn = video_config() 
--  in_max = scrn[10] - length(prompt) - 1 
    in_max = iff(platform()=WINDOWS?video_config()[10]:80) - length(prompt) - 1 

and hypatia\source\hy-lib.e lines 410..463:

--  object scrn -- for calling video_config() 
--      scrn = video_config() 
--      cols = scrn[10] 
        cols = iff(platform()=WINDOWS?video_config()[10]:80)

hypatia\source\hy-lib.e:329  li = trim(li[1..$-1]) 
… 

Thank you Irv and Pete for your efforts! When video_config() is missing under Linux, which is sad news to me, does that mean that get_position() and position() don't work, either? Well, my own fault, to write console programs …

Does the iff(platform()=WINDOWS?video_config()[10]:80) workaround mean that I can rely on 80 to be the default width of a Linux console window? I guess I could live with that, if get_position() and position() work, but if the user changes the window size that would mess things up. Well, they'd have to be told not to.

Btw, it seems you have an old version of my Hypatia code — the recent version is 0.991, and in it I have already renamed some of my own functions, trim among them, where in the age of Euphoria 3.1 I had unwittingly duplicated the names of Phix functions. Also, the input function now allows the user to scroll through past input lines, and edit and re-enter them. hypatia-rpn.net/linux.htm

Thanks again!

I've uploaded a new version (0.991-02) that assumes 80 columns, and that uses prompt_string() instead of my editor, but that way it is only half the fun. Still, anyone who might be willing to test it, you need the new version, for otherwise even if Hypatia compiled and ran, you couldn't input anything.

I still hope that, one day, video_config() and get_position() will work with Linux, but there are probably more important problems to solve in the world. Anyway, thank you!

So, for the time being, I won't try to offer a Linux executable, but I'll update the documentation, include Linux, and tell Linux users that, if they feel adventurous and are able to install Phix on their system, they can compile the program, and to please tell me how it behaves.

So, yeah, not all dreams come true yet, but this is something. Thank you!
