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.
Use %%FAIL IGNORE MSG for error messages that differ on Windows, and
move the sort_by/group_by tests that fail qhen qsort() is not stable.
Now only tests/sorttest and tests/shtest are disabled on Windows.
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.
./jq --run-tests < tests/onig.test

22 of 22 tests passed (0 malformed)
This was an important conflict. In the following expression:
def a: 0; . | a
Bison needs to decide between these two equally valid
parses:
(def a: 0; .) | a
def a: 0; (. | a)
For jq we want the second one, because the first results in
"a/0 is not defined". In the current parser the first parse
is a reduce and the second parse is a shift. Since Bison
prefers to shift in shift/reduce conflicts, we accidentally
got the correct behavior.
This commit adds a precedence level FUNCDEF which is lower
precedence than '|', meaning we explicitly choose the
correct parse.
Of course many unit tests already cover this case, but I
added one specifically for it.
When reporting an error to the user, add information about the offending
object/value (possibly truncated).
The goal is to give a user some context regarding which input object
caused the runtime error.
Examples:
$ echo '"hello"' | ./jq '-.'
jq: error: string ("hello") cannot be negated
$ echo '"very-long-string"' | ./jq '-.'
jq: error: string ("very-long-...) cannot be negated
$ echo '["1",2]' | ./jq '.|join(",")'
jq: error: string (",") and number (2) cannot be added
$ echo '["1","2",{"a":{"b":{"c":33}}}]' | ./jq '.|join(",")'
jq: error: string (",") and object ({"a":{"b":{...) cannot be added
$ echo '{"a":{"b":{"c":33}}}' | ./jq '.a | @tsv'
jq: error: object ({"b":{"c":33}}) cannot be tsv-formatted, only array
