C VM
This is a C implementation of Collapse OS' native words. It allows Collapse OS to run natively on any POSIX environment.
Requirements
You need curses to build the forth executable.
Build
Running make will yield forth and stage executables.
Usage
To play around Collapse OS, you'll want to run ./forth. Refer to
doc/intro.txt for help.
The program is a curses interface with a limited, fixed size so that it can
provide a AT-XY interface. If you wish to change the size of that screen, you
need to modify COLS and LINES in both forth.c and forth.fs.
You can get a REPL by launching the program with rlwrap(1) like
this:
rlwrap -e '' -m -S '> ' ./forth /dev/stdin
Problems?
If the forth executable works badly (hangs, spew garbage, etc.),
it's probably because you've broken your bootstrap binary. It's easy to
mistakenly break. To verify if you've done that, look at your git status. If
stage.bin is modified, try resetting it and then run make clean all. Things
should go better afterwards.
A modified blkfs can also break things (although even with a completely broken
blkfs, you should still get to prompt), you might want to run make pack to
ensure that the blkfs file is in sync with the contents of the blk/ folder.
If that doesn't work, there's also the nuclear option of git reset --hard
and git clean -fxd.
If that still doesn't work, it might be because the current commit you're on is broken, but that is rather rare.
