Stephen Dolan 6828ec9852 Merge pull request #6 from stroan/numeric-comparison-binops 
Add <,>,<=,>= binops
 2012-10-11 07:47:42 -07:00
Stephen Dolan a2643cc0d5 Allow underscores in IDENT tokens. Fixes #3. 
IDENT syntax now includes ASCII letters and underscores, so
'.foo_bar' now works. Non-ASCII letters won't work in IDENT
tokens (it's impossible to tell which non-ascii characters are
"letters" without full unicode tables), so '.données' is still
a syntax error (the workaround is '.["données"]', since you can
put anything you like in a string).
 2012-09-22 14:03:46 +01:00
Stephen Dolan 359d5f33bd Add a bunch of commandline options for controlling I/O format.

Stephen Dolan 25cbab056b Slightly better string interpolation. 2012-09-18 13:22:22 +01:00

Stephen Dolan 8f0c91c032 Add a missing file from prev commit 2012-09-18 12:58:29 +01:00
Stephen Dolan 940f8c4270 Builtin functions defined in jq. 2012-09-18 10:17:38 +01:00
Stephen Dolan 5b9bb64a88 -Werror was a little overzealous. 
Older versions of gcc warn about random things. -Werror makes the
built fail on such compilers.
 2012-09-18 09:43:44 +01:00
Stephen Dolan 7d8d97933f Builtin function 'type'. 2012-09-17 23:06:48 +01:00
Stephen Dolan f13865d7a1 Fix a precedence bug. 
a == b or c == d should obviously parse as (a==b) or (c==d).
 2012-09-17 22:37:51 +01:00
Stephen Dolan 49cf2e67fe Recursive functions + bugfix for stack reallocation. 2012-09-17 22:32:06 +01:00
Stephen Dolan cbdeddbab8 Make the code compile with warnings-as-errors. 
-Wextra found a bona-fide bug: signed/unsigned comparison in a
stack overflow check.
 2012-09-17 22:04:58 +01:00
Stephen Dolan eab9c4e587 Fix debugging code in execute.c so that debug jq compiles again. 2012-09-17 21:43:10 +01:00
Stephen Dolan 830610cef8 Make "not" a builtin function rather than syntax. 
Fixes a really awkward grammar issue.
 2012-09-17 21:08:43 +01:00
Stephen Dolan 297a0679d1 Redefine true and false. Define empty, distict from null. 
This might be the most philosophical commit. I shall ponder it.

true, false, null, empty now defined as bytecoded builtins rather
than calls out to C functions.

Stephen Dolan fe33150b7f Merge branch 'master' of github:stedolan/jq 
Conflicts:
	c/builtin.c
 2012-09-17 20:49:41 +01:00
Stephen Dolan 3db27b01a1 First pass at string interpolation. 
Requires a lexer hack, but a surprisingly un-hideous one. The lexer
maintains a stack of bracket characters so that it can match
parens/brackets/braces to tell where a subexp nested in a string
actually ends.
 2012-09-17 20:41:57 +01:00
Stephen Dolan 326771f4b4 Add a "tostring" function. 2012-09-17 20:14:07 +01:00
Stephen Dolan 9c15ad2021 Support rendering a JSON value to a string buffer. 2012-09-17 20:11:12 +01:00
Stephen Dolan 84ea129f26 Better support for appending strings in JV. 2012-09-17 19:41:41 +01:00
Stephen Dolan 50ebb036c4 Bind builtin functions in a slightly less ugly way. 2012-09-16 17:08:56 +01:00
Stephen Dolan 539156430a Builtin function 'length', for arrays/objects/strings. 2012-09-16 11:08:42 +01:00
Stephen Dolan cc2fb20ca0 Hrm. Update operators (//=, +=, etc.) aren't very well thought out. 
In complex cases, their behaviour is kinda weird. Here's a failing
test for what I think they should do.
 2012-09-16 11:07:36 +01:00
Stephen Dolan df195b3187 Add update operators (+=, -=, *=, /= and //=) 2012-09-11 23:55:59 +01:00
Stephen Dolan f6c6ba95ad Make .[] capable of iteration over objects as well as arrays. 
Also change an assert to a proper error message if it's given
something silly like a number.
 2012-09-11 16:10:55 +01:00
Stephen Dolan d9d6f43407 Pretty-printing of JSON values. 2012-09-11 15:53:37 +01:00
Stephen Dolan 51a44edc63 JSON stream parser. 
Allow multiple values on input as concatenated JSON objects,
possibly separated by whitespace.
 2012-09-11 14:52:10 +01:00
Stephen Dolan 062a6aa6d7 More error handling - locations of refs to undefined symbols. 2012-09-11 12:24:54 +01:00
Stephen Dolan 4c7bede5a4 Better error handling and messages for invalid index/assign operations. 2012-09-11 10:37:44 +01:00
Stephen Dolan 0ce437ea97 More error handling in the parser. 
Add a special case in the lexer to detect unterminated strings.
Add some error recovery in the parser for more copious error spam.
 2012-09-11 10:18:18 +01:00
Stephen Dolan ac3f8bcc52 Proper error messages from lexer errors (e.g. bad characters). 2012-09-11 09:13:20 +01:00
Stephen Dolan 95dd64b0f0 Much, much better error reporting from the parser. 
Getting proper locations through flex/bison was more effort than
was advertised.
 2012-09-11 00:04:47 +01:00
Stephen Dolan 4d47f8f1e1 '==' operator, tests for equality and operator precedence. 2012-09-10 18:08:00 +01:00
Stephen Dolan 3895bbf856 String -> number conversions with "tonumber". 2012-09-10 17:08:13 +01:00
Stephen Dolan aa3ebdfe9b Multiplication and division operators. 
It is an error to use these on anything but numbers. Maybe later
implementing python/ruby-style ("a" * 100) might be handy.
 2012-09-10 16:57:17 +01:00
Stephen Dolan 6f3abbac62 Subtraction - as expected for numbers, ruby-style set diff for arrays. 2012-09-10 16:49:25 +01:00
Stephen Dolan 65ce73deb4 String concatenation. 2012-09-10 16:16:39 +01:00
Stephen Dolan e718bd50b6 Sensible error messages when a silly addition is performed. 
Fix a test to no longer perform an invalid addition.

Stephen Dolan 0159c0ecc5 Plug a memory leak in jv_object_merge 2012-09-10 15:08:58 +01:00
Stephen Dolan 649cac791a Make jv_invalid() first-class values capable of holding an error. 2012-09-10 15:04:19 +01:00
Stephen Dolan 5c25c90657 When comparing two objects for equality, we don't need to recurse 
into e.g. array elements if the two objects are the same array.
 2012-09-10 13:06:46 +01:00
Stephen Dolan c2593dc417 Make a main program that doesn't spam debugging info. 2012-09-10 10:23:15 +01:00

 2012-09-06 21:39:00 +01:00
Stephen Dolan 58a9b0cfe1 Make the test harness not segfault when a test fails (!) 2012-09-04 20:56:44 +01:00
Stephen Dolan da5d653de8 Add a Boolean "not" operator. 
Not wholly convinced this is a good idea, maybe "not" should be a
builtin function instead? 'not (.a == .b)' vs. '.a == .b | not'
 2012-09-04 20:43:40 +01:00
Stephen Dolan 6e6ea50763 Short-circuiting Boolean "and" and "or" operators. 2012-09-04 20:38:59 +01:00

Stephen Dolan 4f747e6fff Move from Jansson to JV - proper freeing of memory 
A few more tests, now passes valgrind.
 2012-09-02 21:45:52 +01:00
Stephen Dolan 9da3e0d373 Clean up build a little and add .gitignore. 2012-09-02 17:24:17 +01:00
Stephen Dolan f72c5ffac0 Move from Jansson to JV - interpreter loop 
Passes tests, but leaks some memory.
 2012-09-02 17:20:13 +01:00

Stephen Dolan 92654f8204 Fix a memory leak when inserting into an object with an already-present key 2012-09-01 18:24:17 +01:00
Stephen Dolan 66fd702363 Minor changes to dtoa.c to make it easier to work with. 
- Change memory allocation to thread a context structure through
   the code rather than using globals (which would require a
   -lpthread and some locking to become threadsafe).

 - Remove a few configuration options (the "private memory" space,
   and K&R style headers).

 - Prefix exported symbols with jvp_ to prevent libc conflicts.

 - Add jvp_dtoa.h

 - Include netlib's g_fmt.c into dtoa.c

 - Add a few not-strictly-necessary initialisations in order to
   compile cleanly with gcc -Wall
