I wanted to make CVM's forth use the Grid subsystem, but doing so would break the stage binary. Hence, this split.

# 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)`][rlwrap] 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.
