Lassi Kortela 78b663d41d Add help and colored banner
- (help ...) is a macro that quotes everything to be user-friendly
- (help* ...) is the equivalent procedure
- When the user types just `help` or `exit`, the REPL shows a hint
  that they are probably looking for `(help)` or `(exit)`.

Lassi Kortela 9d4bf19367 Fix regression in ios_printf implementation
There was some problem with the way the varargs are handled. We had to
need to make (at least one) copy of them with va_copy(). The code is
brittle and I don't understand it, so just rip it all out and replace
with a fixed-size static buffer. It's a hack but we'll soon get rid of
printf completely so this will get us through the day until then.

Lassi Kortela 439eeb2b06 Use vsnprintf() instead of vasprintf()
Windows doesn't reliably offer *asprintf() (sprintf functions that

Lassi Kortela 60ff06fb6d Reorganize error functions and includes
These functions are complicated because they need to be marked
"noreturn" for the compiler. There are several fundamentally
incompatible ways of doing that. Since we have only a few "noreturn"
functions, let's just list all of those in one header file of which
there is a completely different version for each compiler.

Lassi Kortela a6ecac95e1 Rename fs*.c -> os*.c
I planned to put just the file system routines into these files, but
there are starting to be so many of them that I don't want to
duplicate the same set for networking, subprocesses etc.

Lassi Kortela 5ced8d91f6 Store boot image inside main executable
Previously the boot image was kept in the separate file "flisp.boot".
This caused all kinds of problems, as bootstrapping is wont to do. The
biggest problem was finding a portable and convenient pathname for it.

Instead of dealing with all that stuff about how to find the file,
just store the image in a huge C string constant that goes into the
main executable. This necessitates adding a C-string hex dumper into
the Lisp system, and making build.sh slightly more complicated, but
that's a small price to pay for not having to carry a separate file
everywhere we go. Also, flmain.c is a lot simpler now and we don't
have to play around with symlinks.

Lassi Kortela 71098dd01b Fix some "long double" nonsense
Apparently in addition to "float", "double" and "long double" there
are now standard types in <math.h> called "float_t" and "double_t".
Those types don't need to be equivalent to "float" and "double". Gah!
2019-08-13 18:28:19 +03:00
Lassi Kortela 4a89521493 Use 'int' instead of 'char' for character variables
MINIX libc headers define the ctype.h toupper() etc. functions as
preprocessor macros that don't cast their argument to int! So a char
argument causes clang to say "warning: array subscript is of type
'char'".

name extension.
