ChangeLog

2014-06-09  Nicolas Williams  <nico@cryptonector.com>

	Add libm.h to dist file list

	Add note about cmd.exe quoting

	Building docs fails on powerpc (#349)

2014-06-08  Nicolas Williams  <nico@cryptonector.com>

	Update site news

	Also fix configure.ac to use git describe --tags

	Fix scripts/version: use git describe --tags ...
	After tagging as 1.4 scripts/version was still producing jq-1.3-....

	Add `indices(s)`, improve `index(s)`, `rindex(s)`
	Now these deal with arrays as input and `s` being an array or a scalar.

	Improve `index` and `rindex` examples

	Remove reference to `getpath` from docs

	Document `index` and `rindex` (#389)

2014-06-07  Santiago Lapresta  <santiago.lapresta@gmail.com>

	Added `join` function

2014-06-07  Nicolas Williams  <nico@cryptonector.com>

	String * number should be commutative

2014-06-04  Nicolas Williams  <nico@cryptonector.com>

	Add cross-compilation notes to README
	A detailed set of instruction as to how to setup a cross-compilation
	environment for OS X and Win32/64 would be nice.

	Add -j option to scripts/crosscompile

	Add flags argument to jv_parser_new()
	For extensibility.  We might add streaming parser options, even binary
	JSON encoding options.

2014-06-02  Nicolas Williams  <nico@cryptonector.com>

	Fix tests failures on Windows
	And Solaris 8 and 9 too, no doubt.  The problem was that non-standard
	vsnprintf()s that return -1 when the buffer is too small were not
	properly supported.

2014-05-20  Santiago Lapresta  <santiago.lapresta@gmail.com>

	Documented `del` command

2014-05-11  Santiago Lapresta  <santiago.lapresta@gmail.com>

	Added texts/examples to unique_by function

	Added unique_by function

2014-04-17  Nicolas Williams  <nico@cryptonector.com>

	Make pthread tls configurable for Mingw build
	For the Mingw build we don't want to pull in the pthread DLL just
	because we can autodetect pthread support.  That would make the jq.exe
	binary not self-contained.

2014-04-16  Nicolas Williams  <nico@cryptonector.com>

	Add autoconf checks for pthreads; fix #340

2014-03-20  Jingwen Owen Ou  <jingweno@gmail.com>

	Add link to jqplay

2014-03-13  Nicolas Williams  <nico@cryptonector.com>

	Fix for #303 in the sources

2014-03-13  Santiago Lapresta  <santiago.lapresta@gmail.com>

	Added `arrays` and other filters
	Arrays, objects, numbers, strings, booleans, nulls, values (non-nulls)
	-- these builtins filter out those inputs that don't match the name of
	the builtin.

	This fixes #322 and #324.

2014-03-07  Filippo Valsorda  <filippo.valsorda@gmail.com>

	Add a recursive object merge strategy and bind it to *
	This commit adds a jv_object_merge_recursive function, that performs
	recursive object merging, and binds it to multiply when applied to
	two objects.

	Closes #320

2014-03-06  Nicolas Williams  <nico@cryptonector.com>

	Make libm tests more portable

2014-02-26  Andrew Rodland  <andrew@cleverdomain.org>

	Repair jv_show

2014-02-26  Andrew Rodland  <andrew@cleverdomain.org>

	Make jq --raw-output --unbuffered work
	--unbuffered was only affecting the normal output case, not the --raw-output case. Make the two of them play together.

	This also makes sure that the output is flushed *after* printing the newline, so a consumer doesn't lag a line behind.

2014-02-21  Nicolas Williams  <nico@cryptonector.com>

	Add cbrt (cube root)

	Add missing trig functions and barebones test

	Remove non-standard exp10()

2014-02-21  Mike McCabe  <mccabe@archive.org>

	Initial add of math functions.

2014-02-20  Nicolas Williams  <nico@cryptonector.com>

	Add `?`, `.[]?`, and `..` operators
	Make XPath-like `//a/b` recursive structure traversal easier in jq,
	which then becomes:

	    ..|.a?.b?

	The `?` operator suppresses errors about . not being an array or object.
	The `..` operator is equivalent to calling the new `recurse_down`
	built-in, which in turn is equivalent to

	    recurse(.[]?)

	Note that `..a` is not supported; neither is `...a`.  That could be add
	added, but it doesn't seem worth the trouble of saving the need to type
	a '|'.

2014-02-16  Santiago Lapresta  <santiago.lapresta@gmail.com>

	Added `all` and `any` builtins

2014-01-25  polyester  <paul@cleanclothes.org>

	work with newer versions of automake
	when using a newer automake, the autoreconf step fails with warnings:
	"linking libtool libraries using a non-POSIX archiver requires 'AM_PROG_AR' in 'configure.ac' "

	This happens for instance on ubuntu 13.10.
	Doing just that, adding 'AM_PROG_AR' to configure.ac fixes the problem.

2014-01-01  Nicolas Williams  <nico@cryptonector.com>

	Fix #201; check that bison accepts --warnings

2013-12-27  Joe Littlejohn  <joe.littlejohn@nokia.com>

	Fix rpm build (`make rpm`)
	* Re-add VERSION as it's required for `./setup superclean`
	  and `make rpm`.
	* Add *.rpm to git ignore, we never want them under version control.

2013-12-27  Filippo Giunchedi  <fgiunchedi@gmail.com>

	include additional files in jq.spec
	this will probably need changing upon SONAME bump

	fix rpm Makefile target and prerequisites
	depend on dist and the specfile, plus use automake's variables

2013-12-26  Nicolas Williams  <nico@cryptonector.com>

	Document --version

2013-12-26  Nicolas Williams  <nico@cryptonector.com>

	Add jv_dumpf() and jv_show()
	jv_dumpf() takes a FILE *.

	jv_show() is intended for use in debuggers, so it dumps the jv to stderr
	and it does not jv_free() the jv, so it's safe to
	"call jv_show(some_jv, -1)" in a debugger.  If flags == -1 then the jv
	will be shown pretty-printed and in color.

2013-12-26  Nicolas Williams  <nico@cryptonector.com>

	Document .foo.bar in manual

	Document exit numbers

	Normalize errors for -e

2013-12-25  Nicolas Williams  <nico@cryptonector.com>

	Fix doc typos (.[foo] wanted to be .["foo"])

	Add note to jq.1 about shell quoting

2013-12-20  Philipp Hagemeister  <phihag@phihag.de>

	Ignore the config/test-driver file
	This file is automatically generated and does not need to be committed.

	Fix @uri example
	Previously, the @uri example didn't match the actual behavior of the current jq, as exclamation marks do not need to be encoded in URIs.
	Replace the example with an input that needs encoding, and is encoded by jq.

2013-12-17  Stephen Dolan  <mu@netsoc.tcd.ie>

	Allow negated object values without parens. Fixes #247

2013-12-17  Nicolas Williams  <nico@cryptonector.com>

	Fix memmem() error

2013-12-13  Rémy Léone  <remy.leone@gmail.com>

	Adding a .travis.yml file to use the travis-ci.org
	From wikipedia:

	Travis CI is a hosted, distributed continuous integration service used
	to build and test projects hosted at GitHub.

	Travis CI is configured by adding a file named .travis.yml, which is a
	YAML format text file, to the root directory of the GitHub repository.

	Travis CI automatically detects when a commit has been made and pushed
	to a GitHub repository that is using Travis CI, and each time this
	happens, it will try to build the project and run tests. This includes
	commits to all branches, not just to the master branch. When that
	process has completed, it will notify a developer in the way it has been
	configured to do so — for example, by sending an email containing the
	test results (showing success or failure), or by posting a message on an
	IRC channel. It can be configured to run the tests on a range of
	different machines, with different software installed (such as older
	versions of a programming language, to test for compatibility).

2013-12-13  Stephen Dolan  <mu@netsoc.tcd.ie>

	Make the testsuite run on machines without valgrind

	Format more integers as integers, not scientific notation.
	jq is now willing to put up to 15 zeros after an integer before
	moving to scientific notation.

2013-12-11  Nicolas Williams  <nico@cryptonector.com>

	Complete more-arity feature not complete
	And test

	convert range bounds to integers in a way that avoids undefined behaviour

	add checking of numeric indices to an array to see if they can reasonably be considered integers. Avoid undefined behaviour if out of bounds

2013-12-09  David R. MacIver  <david@drmaciver.com>

	some functions were missing prototypes. Add them

2013-12-08  David R. MacIver  <david@drmaciver.com>

	These vfprintfs are being used as if they were printfs. Fix that

	consistent use of goto out in main

2013-12-08  Stephen Dolan  <mu@netsoc.tcd.ie>

	Refactor jv structure.
	New structure layout is simpler and also faster.  In particular, it's
	now small enough to be passed in registers on amd64.

	Make testsuite not leak when compiled with -DNDEBUG.

2013-12-08  David R. MacIver  <david@drmaciver.com>

	test for losing memory on compile errors

	Use uint32_t for codepoint in  jv_string_append_codepoint()

	Add jv string utility functions
	    jv_string_empty()
	        -> return an empty string with given allocated length (for fast
	           appends)
	    jv_string_append_codepoint
	        -> append a single codepoint (int) to the given string
	    jv_string_explode

	Add a --unbuffered option. Closes #206

2013-11-07  Peter van Dijk  <peter@7bits.nl>

	count should be length

	Closes #129.

2013-05-23  Nicolas Williams  <nico@cryptonector.com>
