Avoid the "expected a positive width" display error when printing
sequences with no width remaining.
* module/ice-9/pretty-print (print-sequence): test for zero width when
printing sequences
This is a followup to a4e4722944 ("need
read error for extra closing square brackets".)
* test-suite/tests/reader.test (exception:unexpected-rsqbracket): New
variable.
("reading")["paren mismatch (2)"]: Change exception type to
EXCEPTION:UNEXPECTED-RSQBRACKET.

mismatched opening"]: New test.
* module/ice-9/pretty-print.scm (generic-write)[pp-SYNTAX-CASE]: New
procedure.
[style]: Add support for `define-public', `define-syntax',
`let-syntax', `letrec-syntax', `syntax-rules', and `syntax-case'.
* module/web/toy-server.scm (serve-client): Fix up error handling, so we
catch errors when reading, handling, and writing. If we run
interactively, an error will enter the debugger.
* module/ice-9/pretty-print.scm (generic-write)[wr]: Handle read macros
that appear in the middle of a list.
* test-suite/tests/print.test (prints?): New macro.
("pretty-print"): New test prefix.
* module/web/http.scm: New module, declares known HTTP headers, and
their parsers and unparsers.
* test-suite/tests/web-http.test: Add test suite.
* module/Makefile.am:
* test-suite/Makefile.am: Adapt.
* module/web/uri.scm (uri-error): New proc, throws to 'uri-error.
(validate-uri, uri-decode, uri-encode): Use uri-error.
* test-suite/tests/web-uri.test: Update for uri-error.
* module/srfi/srfi-38.scm: New file, partly based on the reference
implementation and on Alex Shinn's public-domain implementation for
Chicken.
* module/Makefile.am (SRFI_SOURCES): Add srfi/srfi-38.scm.
* test-suite/tests/srfi-38.test: New file, minimal test suite for SRFI
38.
* test-suite/Makefile.am (SCM_TESTS): Added tests/srfi-38.test.
* doc/ref/srfi-modules.texi: Add a node for SRFI 38.

This allows customizing the reader behavior for a dynamic extent more easily.
* libguile/read.c (scm_read_hash_procedures): Renamed to
`scm_i_read_hash_procedures'.
(scm_i_read_hash_procedures_ref, scm_i_read_hash_procedures_set_x):
New (internal) accessor functions for the fluid.
(scm_read_hash_extend, scm_get_hash_procedure): Use these accessor
functions.
(scm_init_read): Create the fluid, named `%read-hash-procedures' instead of
the previous plain list `read-hash-procedures'.
* test-suite/tests/reader.test: Adapt the "R6RS/SRFI-30 block comment
syntax overridden" test to make use of the fluid.
* module/ice-9/deprecated.scm (read-hash-procedures):
New identifier macro -- backward-compatibility shim.

Because that probably isn't where people will look for it.
Thanks to Noah Lavine for the idea.
* doc/ref/api-regex.texi (Regular Expressions): New file, containing
the regex doc (promoted one level) that used to be in api-data.texi.
* doc/ref/guile.texi (API Reference): Include new file, and add menu
entry for the new section.
* THANKS: Add Noah.
* benchmark-suite/benchmarks/arithmetic.bm (repeat): Change the syntax.
Add support for binary OP.
("fixnum")["1+", "1-"]: Adjust accordingly.
["+", "-"]: New benchmarks.
Reimplement record-type descriptors as vtables for record structs, saving
us what was an expensive inspection of a record's vtable layout string to
determine its type.
* module/rnrs/records/inspection.scm (record-field-mutable?): Check
mutability using the bit field stored in the record-type descriptor
instead of the record struct's vtable.
* module/rnrs/records/procedural.scm (record-internal?): Reimplement as a
delegation to a check of the passed struct's vtable against
`record-type-descriptor?'.
(record-type-vtable): Modify to include base vtable layout as a prefix
of the record-type-descriptor layout so that all record-type instances
are now also vtables.
(make-record-type-descriptor): Remove field vtable; build up a mutability
bit field to use for fast mutability checks.
(record-accessor, record-mutator): Use field struct and mutability bit
field.
* module/language/tree-il/analyze.scm (gensym?): New procedure.
(unused-variable-analysis): Ignore variables whose name passes
`gensym?' or is `_'.
(unused-toplevel-analysis): Ignore variables whose name passes
`gensym?'.
* test-suite/tests/tree-il.test ("warnings")["unused-variable"]("special
variable names"): New test.
["unused-toplevel"]("special variable names"): New test.
* libguile/threads.c:
* libguile/posix.c: Change a couple #if HAVE_FOO to #ifdef HAVE_FOO to
pacify -Wundef. Some vars are defined or not, whereas some are always
defined to 0 or 1. The inconsistency is unfortunate.
* libguile/Makefile.am (chknew-E chknew-SIG): Run gcc without `-undef'
since otherwise it ends up trying to include headers that are not
available (e.g., <gnu/stubs-32.h> on an x86_64-linux-gnu system.)
* module/sxml/ssax.scm (reset-parsed-entity-definitions!)
(define-parsed-entity!): New heavy-handed knobs for adding to the set
of parsed entity definitions.
These sections are pretty similar in aim, but `Tutorial' is mostly
better material.
* doc/ref/goops-tutorial.texi (Class definition): Add a sentence about
what slots are.
* doc/ref/goops-tutorial.texi (Tutorial): Remove repetition of the Stk
origin, and index entries that are overly general in the context of
the whole Guile manual.
(Generic functions): Add text here about the nature of methods,
previously in Quick Start.
* doc/ref/goops.texi (Quick Start): Move `Built-in classes' subsection
to be part of `Introspection'. Delete the rest, apart from snippets
moved into Tutorial.
* libguile/vm-i-system.c (VM_DEFINE_INSTRUCTION): Drop the stack items
corresponding the the with-fluids object. Thanks very much to Stefan
Israelsson Tampe for the fix.
* libguile/vm-i-scheme.c (INUM_MAX, INUM_MIN): New macros.
(add1, sub1): Add/subtract without untagging the operand. This leads
to a 44% run time improvement compared to the previous
implementation.
* libguile/vm.c: Include <stdint.h>.
* test-suite/tests/numbers.test ("1+", "1-"): Add tests for
MOST-POSITIVE-FIXNUM, resp. MOST-NEGATIVE-FIXNUM, for 32-bit and
34-bit values thereof.
* benchmark-suite/benchmarks/arithmetic.bm: New file.
* benchmark-suite/Makefile.am (SCM_BENCHMARKS): Add it.
* doc/ref/goops.texi (Adding Methods to Generic Functions): Move the
bit about no applicable methods to `Invoking Generic Functions'.
Other minor edits.
(Basic Method Definition): Flattened into parent.
(Method Definition Internals): Moved to MOP section at end of
chapter.
