"create".

ec10295143 FICL 2.05 has a flawed definition of BASE. Fix it.

49acc8fe50 Bring in ficl 2.05.
This version has a step debugger, which now completely replaces the
old trace feature. Also, we moved all of the FreeBSD-specific MI
code to loader.c, reducing the diff between this and the official
FICL distribution.

4eedebf31f Only build PnP parts if the platform supports PnP. 2000-09-10 12:15:30 +00:00

f5da975f8f Add the infrastructure necessary to handle PnP from a Forth script.
Also, export the file_findfile() function. Again, this is taken from
work in progress but frozen for the time being. Since it works, I'd
rather commit and remove any uglyness later than hide it on my tree.

70e1899762 Fix REFILL. It must throw RESTART instead of OUTOFTEXT so that
execution can take place at the point where it stopped after the
input buffer has been refilled.

Add ANS Forth CORE EXT and FILE word SOURCE-ID.

7505875a0a The previous fix for "type" was absolutely lousy. Not only the buffer
allocated was not big enough, but it ended up to being used where it
was supposed to be used. The person who did that ought to be shot, but
since I'm a good person, I'll forgive myself...

e9583ef187 From the PR:
I added a FICL_TRACE-conditioned trace facility based on "see".
It is ugly because words' functions are almost all static, and ficlExec,
where the trace has to be located, can't get their pointers. So, #ifdef
this staticization, and add most of see's body into ficlExec. Duplication
of code, uglyness, etc. But it is cleanly #ifdef'ed, and works like a
charm.

	It does not provide "step" facility, though, just trace. It is
tunable at run-time through "trace!". If anyone (most likely me :) ever
wants a step facility, I'll add it. Should be easy.

f7f7a5d7ab From the PR:
FICL's TYPE copies the counted string to HERE, as abial has
remarked. Answering to abial's question, this is NOT garanteed to have
enough space.
...
	We have dynamic memory. Even before memory-alloc got in, we
already had dynamic memory. Use it, then! (ficlMalloc is sysdep, so I
suppose that's why it was not used for TYPE; ficl is probably designed
to work without a working ficlFree).

6a80a16d7d Add EXCEPTION word set.
Make TIB handling use buffer size to conform with ANS Forth.

Add ANS MEMORY-ALLOC word set.

c82de3cb3f Add words "pc!" and "pc@" which allow to manipulate I/O ports. This can
be helpful when directly fiddling with PC hardware.

Also, define "arch-i386" appropriately, as suggested by Daniel C. Sobral.

8f1e6e6e22 Add support for some FACILITY words:
key? ( -- flag)  \ check to see if there's a key to be read from input
ms   ( u -- )    \ wait that many milliseconds
seconds ( -- u ) \ get number of seconds from midnight.

'words' now outputs the list page by page - this probably should go
through libstand's pager, but will have to wait for closer integration of
built-ins with Forth...

ac19ebdfbe Add new word ".#" which acts like "." but doesn't output a space separator.
I found it impossible to output parametrized strings like "\033[%d;%dH"
without building them first in pad area.

37869e957d o Add proper stack checking to all file words
o add fkey and fread
o eliminate fexists now that this can be expressed in HLL forth
  ( : fexists fopen dup -1 <> if fclose 1 else drop 0 then ; ) :-)

Once we get the ability to write files, it should be possible to do
stand-alone rescue work from the 3rd stage boot. :)

82f35547c9 Remember a bit more of my forth and do:
o Add fexists word to check for the presence of a file
o make fexists and fload immediate words which DTRT both interpreted
  and compiled (doh!)
o add an init word which gets run at bootstrapping time to do extra
  post-coldload initialization (in the default implementation, we
  look for /boot/boot.4th and load it if found).

780ebb4b00 Add the Ficl (Forth Inspired Command Language) interpreter. If all goes well,
this will allow us to manage bloat in the loader by using a bytecoded HLL
rather than lots of C code.  It also offers an opportunity for vendors
or others with special applications to significantly customise the boot
process without having to commit to a divergent code branch.

This early commit is to allow others to experiment with the most effective
mechanisms for integrating FICL with the loader as it currently stands.
