Denial

Thanks for the information. This is the new version: int p = 4613; POKE(p++, 147); // load POKE(p++, 34); // " memcpy((void*)p, cmd, strlen(cmd)); p += strlen(cmd); POKE(p++, 34); // " POKE(p++, 44); // , POKE(p++, 56); // 8 POKE(p++, 0); POKEW(p, 0); // prg end POKE(45,PEEK(34)); // set f...

I've gone a bit forward but still have problems. This is the current code: char* str = "\"ciao.prg\",8"; // sample loading basic code POKE(4610, 1); // ? POKE(4613, 156); // clr POKE(4614, 58); // : POKE(4615, 147); // load memcpy((void*)4616, str, strlen(str)); memset((void*)(46...

I agree with all of you, maybe it's a useless program.
Nevertheless I'm having fun making it and I think it's a cool project; and since I do not do it for work, that's enough for me to go on

Currently it's a standalone program with the basic built-in commands like ls, more, source, cp, mv, etc. It can execute "scripts" but only containing the built-in commands or launch other programs (no language constructs). It has working wildcard expansion, aliases and some other features.

Have you ever used a Unix like shell?
Even if you find it useless, it's funny to do and pretty cool, IMHO.
Your mileage may vary

Could you please try this apk: http://www.opbyte.it/vic20/vice-vic20-android_alpha4.apk It should fix the bug you reported. There is still a problem with the arm version of your cpu: if you have an old armv6, it will probably crash. This is caused by a problem with all the compiling scripts which me...

Thanks very much for the logcat. It looks like the View.addOnLayoutChangeListener() is not available on your system, and the api documentation says it's indeed from android 3.0. Now, why the compiler didn't tell me I was requesting an api call which is not available on the target system, is a mister...

Now it's mostly working.

What's missing:

- program execution
- fitting 16k
- "ls" options
- chdir and pwd can manage devices only, no subdirs

Thanks.
Probably, I also need to relocate the loading code somewhere it's not touched by the load call itself (like the cassette buffer?), and run it from there.
I fear it's not trivial to do it in C and I should start looking at asm code closer

Hello, for my upcoming shell, I need to make a routine to run a prg file from my C code. i have taken a couple lines of code from cbm filebrowser which does: JSR $C533 ; Relinks BASIC Program from and to any address... JMP $C7AE ; BASIC Warm Start (RUN) so I did: if (cbm_load(cmd, 8, NULL) > 0) asm(...

Turned out it was a compiler problem indeed. Reverted some svn revisions back and now, no more crashes!
Let me fix some more evident bugs and then I'll post it.
Cheers!

Progress: I was able to compile a heavily modified sash but it crashes like hell. I think it's because I'm using the svn version of cc65. I can't use the stable one because it misses some features I need. Changing an empty loop from 0 iterations to some causes a crash, so it must be something relate...

I've seen tape programs auto-running themselves, I suppose they fiddle with the start address or something.

Thanks Mike for the information. I didn't have much time this weekend to work on this, but I did have a look around to see what minimal shells, written in C, are available. There are a lot, because of the use in embedded systems, network equipment etc. There is one that is promising, it's called &qu...

Update: cbmsh now has its own web page: http://www.opbyte.it/cbmsh/ But this thread will continue to be the main discussion resource. *** Original post: *** I was looking for a unix-like shell (or of any kind) for the vic but couldn't find any. So I thought I could make one, but I've got too many un...
