Also, remove extraneous uses of it. In the rdln routine, we would spit a new line after each line input, but that NL was spurious: we already spit the newline we receive as it is typed. |

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.
