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 b2027fe023 Split setenv/unsetenv by platform

Lassi Kortela 6ffe6bf174 Add truly sinful float hacks for Watcom 2019-08-21 22:11:05 +03:00
Lassi Kortela 439eeb2b06 Use vsnprintf() instead of vasprintf() 
Windows doesn't reliably offer *asprintf() (sprintf functions that
automatically malloc as much memory as they need) so hand-roll the
equivalent on all platforms.
 2019-08-21 22:10:13 +03:00
Lassi Kortela c76379e6f5 Brace try/except in main() for Watcom 2019-08-21 22:08:21 +03:00
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.

Fills a "struct buf" with the entire remainder of a stream.
 2019-08-14 13:39:11 +03:00
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.
 2019-08-14 01:15:29 +03:00
Lassi Kortela bf11066313 Add stubs for Haiku, Minix and Solaris 2019-08-14 00:01:26 +03:00
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.
 2019-08-13 23:07:44 +03:00
Lassi Kortela 2e8153019c Add read-u8 built-in (R7RS) 
io.getc gets UTF-8 characters
 2019-08-13 22:53:37 +03:00
Lassi Kortela c2da0753af Fix some more "long double" nonsense 2019-08-13 18:51:43 +03:00
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'".

Lassi Kortela 3b13e81eae Add concept of built-in libraries and (import) statement 
R7RS syntax is: (import (library name here))

We translate this into the internal path "library/name/here". This will allow
us to easily load libraries from files later on by appending the ".sld" file
name extension.

 2019-08-10 01:01:40 +03:00
Lassi Kortela 2ec07684d2 Get OS name from uname() 
This implies that OS names have changed. Unix-like OS names are now
capitalized. "macos" is now "Darwin". Windows is now all-lowecase "windows".
"win32" is gone. "win64" was not used in the original code despite a reference
to it.

 2019-08-10 00:12:33 +03:00
Lassi Kortela 267cd00146 Remove unnecessary ifdef about unsetenv() return value

 2019-08-10 00:05:31 +03:00
Lassi Kortela 95a1c1032c Remove ifdef about memrchr() on MacOS 
MacOS doesn't have memrchr() so there was an ifdef with a custom
implementation for it. Get rid of the ifdef by always using the custom
implementation.

Lassi Kortela 1d96278313 Break down dirpath.c into fs_*.c by OS 
I much prefer this to using ifdefs. Requires a little help from the build
system but I find it worth it.

Lassi Kortela e19fe0b8bd Remove time.string and time.fromstring builtins

Lassi Kortela c84c71adcc Get rid of INLINE and STATIC_INLINE 
Nowadays compilers have good optimizers that know when to inline static
functions depending on the user's chosen optimization level (and speed vs size
optimization). We don't need to annotate functions manually.

are apparently semi-standard nowadays.

Lassi Kortela d6a4029dde Replace idiosyncratic C types with standard ones 
For number types, we rely on classic C types (char, short, int, long) to be
the correct sizes. For precise bit widths, use standard intN_t and uintN_t.
For size_t, just use system size_t.
