Lambdas rotted because there wasn't any test for them, and after
return type moved to the end, lambdas stayed assumning it in the
front. We fix this and add test program
sextest resolves #+ and #- itself -- it reads the program and prints
what survives to sexc -- so a flag spelling it does not recognise
decides which branch gets compiled
The guard against nested pointer chains searched every sublist for a
`*', including the ones that hold a type of their own.
A function type with a pointer parameter, while the same type with an int
parameter passed. (* [char 4]) was let through as well and came out
as `vector-ref char 4 * p'.
A `*' inside an array or a function type belongs to that type, so the
search stops there. What the flat conversion cannot express is now
named: a fn type is a function pointer already, and a pointer to an
array is not supported.
Parameters of a function type are walked without their names. C writes
a parameter name into a declarator and a type has none, so fmt-c prints
whatever it is handed there as a type: `(s (* char))' came out as
`char(*) s'.
fmt-c printed a nameless array declarator's #f into the C, which showed
up in these parameters.
C has two namespaces and the database had one. A typedef of a tag's
name wiped it.
Tags, i.e. struct, enum and union, share one namespace; they move to a
table of their own. A name resolves the way C does: the ordinary
identifier first, the tag when that leads nowhere.
While resolving a typedef, the target was taken apart with cadr
whatever it was, so (typedef points (¤ point 4)) reported point's
fields as its own -- an array of four points claiming to be a point,
and a macro reaching through it with v->x. Only a name and
(struct|union|enum NAME) name a type now.
A dropped datum is replaced by whatever follows it, but what follows
may be the end of the file or the paren closing the list we are
in. Hand the token back to the caller instead: read-list closes its
list with it and the toplevel loop stops.
A `;' comment between a guard and the form it guards was also taken for
the guarded datum, so the form stayed unconditional and the guard did
nothing. Skip comments when reading the guard.
comment-form? was defined three times over; it moves to utils.
<OpenGL/gl3.h> does not exist there and -framework is not a gcc flag,
so the documented build line failed with no hint why. #+macosx picks
the header now, and both build lines are in the file -- pkg-config
carries the flags on either platform, apart from Apple's GL framework,
which has no pkg-config file to carry.
'#+' and '#-' introduce conditional compilation: the form that follows
is kept only when the feature expression is true, and otherwise is read
and thrown away. An expression is a feature name, or and / or / not
of them.
They are read time, not compile time.
Default features are the host's software-version, software-type and
machine-type as CHICKEN reports them, plus what --features flag adds.
1. Look for `compilation', not `compile' among the source
2. Read the file with provided --features from the (compilation ...)
form, then handle resulting file to sexc
compile-to-file returned process-wait's values and main dropped them,
so cc errors were printed, but then main compiler exited 0.
Also cleanup tmp C files when compilation failed.
Implement pub support for enums, and also anonymous enums declared
in-place.
Also give the cdr of a `pub' form the form's own location, so a
error about what follows `pub' can say where it was written
For source-level debug. Add --line-directives option, defaulted to
statement. Disabled when used with -C. Explicit non-none value
overrides disabling when -C is present
