Nicolas Williams 6f9646a44f Improve docs somewhat, inspired by #1326 2017-01-30 14:11:05 -06:00
Nicolas Williams bd7b48c1b9 Make |= delete LHS when RHS is empty (Fix #1314) 
Now that #1313 is fixed, |= no longer outputs null when the RHS update
expression outputs empty.

When a user wants to keep the current value of the LHS they would have
the RHS update expression output `.`, so having `empty` achieve the same
thing would be redundant.  The obvious thing to do is to delete the LHS
when the RHS update outputs `empty` (i.e., doesn't output any values).

It's reasonable to think that existing programs won't be broken by this
change, because reduce and |= not handling empty well is clearly a bug.
(Though it's possible that some programs were using empty to quickly
terminate reduce or |=, it's not likely.  They should use label/break
instead.)

Prior to this change |= would use the _last_ value output by the RHS
update expression.  With this change |= will use the _first_ value
instead.  This change _is_ a minor backwards-incompatible change.  It
may or may not be acceptable; we'll see.  It is a useful change in that
it makes |= faster when the update expression produces multiple values.

Nicolas Williams 7bdf3a39ad Add SQL-style operators (#1322) 2017-01-30 14:11:05 -06:00
Nicolas Williams 396543191c Make first(g) more efficient: extract only 1 value 
first(g) was extracting two values, which, if g is slow, made first(g)
slow.  And if the second extraction were to throw an error, then
first(g) would throw that error, which is clearly not the right thing to
do.  Besides that, first(g) was allocating garbage, which it no longer
does.

William Langford e84d17196c Handle cut-off UTF-8 sequences when reading files 
Read additional bytes from the file to complete the UTF-8 sequence so the bytes
in it don't get converted to U+FFFD replacement characters.

This addresses #1136, and mitigates a stack exhaustion when printing
a very deeply nested term.

Jan Schulz 4337fc5fe0 Build on windows (mingw) on appveyor 
For this to work, one of the core commiter should do:

* enable appveyor in the github project (grant access)
* Make an appveyor account and add the github jq repo as a new project

inspirations from:

appveyor, msys2, use bash environment to build...

Nicolas Williams 8f6f28c8d3 Make it easier to use jq with shebangs (fix #1044) 
Allow a continuation on a comment immediately after a shebang to make
this traditional hack possible:

    #!/bin/sh
    # this next line is ignored by jq \
    exec jq -f "$0" "$@"
    # jq code follows

But continue only on the first line following a shebang, and only if
it's a comment.
