* stream.h (struct json_opts): Member flat removed.
I noticed that !jo.flat was always being tested together
with jo.fmt == json_fmt_standard. Except for a few
places where the code only tested for json_fmt_standard,
resulting in flat output, but some extra spaces.
What distiguishes flat mode now is simply that we
disable stream indentation.
* lib.c (out_json_rec): Remove tests for !jo.flat.
(out_json): Remove initialization of jo.flat member.
In this function we set up indentation on the stream
resulting in multi-line mode (existing behavior).
(put_json): Remove initialization of jo.flat member.
If flat mode is requested, then it overrides the
format to json_fmt_default. I.e. json_fmt_standard
coresponding to :standard is only in effect if flat
is not requested.
In this function we set up indentation on the stream
if flat mode isn't requested, otherwise we disable
indentation (existing behavior, enough to make flat
work).
* tests/010/json.tl: Tests for flat mode, :standard
formatting, and combinaton of both.

* parser.h (struct parser): New member, read_json_int.
* parser.c (read_json_int_s): New symbol variable
for *read-json-int* symbol.
(parser_common_init): Look up value of *read-json-int*
and store in read_json_int struct member.
(parse_init): Initialize read_json_int_s with interned
symbol and also register the dynamic variable.
* parser.l (grammar): Extend the {JNUM} rule to check
the read_json_int flag and produce an integer value if
the lexeme does not contain a decimal point, e or E.
* tests/010/json.tl: New tests.
* txr.1: Documented.
* lex.yy.c.shipped: Regenerated.

I've run into situations in which I wanted a comment in a
big JSON quasiliteral to explain some embedded piece of code.
We support only semicolon comments, and no #; ignore notation.
* parser.l (grammar): Recognize Lisp comments in the JSON
state also. That does it.
* tests/010/json.tl: One modest little test.
* txr.1: Documented.
* lex.yy.c.shipped: Regenerated.

* lib.c (out_json_rec): Handle NUM and BGNUM cases same as FLNUM
so integers get printed. The restriction against integers has
been largely unhelpful and bothersome. Handle LCONS together with
CONS. Lists that are not special notation fall through to the VEC
case, which now uses seq_iter_t iteration to handle vectors and lists.
* tests/010/json.tl: New tests.
* txr.1: Documented support for printing integers and lists.

* tests/010/json.tl: New tests. These work. Odd; I'm seeing
an issue whereby typing multi-line #J expressions into the
listener does not work.

* parser.c (read_bad_json_s): New symbol variable.
(parser_common_init): Propagate value of *read-bad-json* into
read_bad_json flag in parser structure.
(parser_init): Initialize read_bad_json_s and register the
*read-bad-json* dynamic variable.
* parser.h (struct parser): New member, read_bad_json.
(read_bad_json_s): Declared.
* parser.y (json_val): Support an opt_comma symbol just before
the closing bracket or brace.
(opt_comma): New nonterminal symbol. Recognizes ',' or nothing.
Error is flagged if ',' is recognized, and *read-bad-json*
is nil.
* y.tab.c.shipped: Updated.
* tests/010/json.tl: New tests.
* txr.1: Documented.

* tests/002/query-1.txr: Skip test if an executable
/bin/sh doesn't exist, rather than the bogus reasons.
* tests/010/json.tl: Change the condition for the
command-put-json tests: not whether cat is found
in the search path but whether /bin/sh exists and is executable.
* tests/017/realpath.tl: Also quit if /usr/bin doesn't exist.
* tests/018/path-test.tl: Exit succesfully if /bin/sh
does not exist. Revert the earlier change.
* tests/018/process.tl: Quit if no executable /bin/sh exists.

* tests/010/json.tl: skip several test cases which rely on the
cat utility for testing command-put-json, if the cat utility
is not found in the search path. Reported and investigated by
Paul A. Patience.

* tests/010/json.tl: Fix several tests being excluded from
the (mtest ...) form to which they are expected to belong,
one of them having an extra quote in the expected value, too.

* parser.c (lisp_parse_impl): If parsing from string, check
for trailing junk and diagnose. JSON parsing doesn't use
lookahead because it doesn't have a.b syntax, so the
recent_tok gives the last token that actually went into the
syntax, and not a lookahead token. So in the case of JSON,
we call yylex to see if there is any trailing token.
* tests/010/json.tl: Extend get-json tests to more kinds of
objects, and then replicate with trailing whitespace and
trailing junk to provide coverage for these cases.
* tests/012/parse.t: Slew of new read tests and iread also.
* txr.1: Documented.

* lib.c (out_json_str): Strengthen the test for escaping the
forward slash. It has to occur in the sequence </script
rather than just </. Recognize <!-- and --> in the string,
and encode them.
* tests/010/json.tl: Cover this area with some tests.
* txr.1: Documented.

* tests/010/json.tl: on Windows characters are limited to the
BMP range 0 to #\xFFFF. The character escape \x10437 is out
of range, and so throws an error, simply from that syntax
being read. The two test cases which use this character are
clumped into their own test form, which is executed
conditionally on wide characters being more than two bytes.
Because the expression is still parsed on Windows, we read the
troublesome character from a string at run-time, and
interpolate it.

* /share/txr/stdlib/getput.tl (get-jsons): If the s parameter
is a string, convert it to a byte input stream so that.
(put-jsons): Add missing t return value.
(file-put-json, file-append-json, file-put-jsons,
file-append-jsons, command-put-jsons, command-put-jsons): Add
missing object argument to all these functions, and a missing
"w" open-file mode to several of them.
* stream.c (mkstemp_wrap): Calculate length of suff the
defaulted argument, not the raw suffix argument.
* test/010/json.tl: New file, providing tests that touch every
area of the new JSON functionality.
* tests/common.tl (mstest, with-temp-file): New macros.
* txr.1: Document that get-jsons takes a source which could be
a string.
