This is the last bit of "python" left in the notmuch codebase. https://www.python.org/dev/peps/pep-0394/#recommendation encourages "third-party distributors" to use more-specific shebang lines. I'm not certain that the notmuch project itself is a "third-party contributor" but I think this is a safe way to encourage people to use python3 when they're developing notmuch. We already have python3 explicitly elsewhere in the codebase for developers (in nmbug). Signed-off-by: Daniel Kahn Gillmor <dkg@fifthhorseman.net>

|
|
|
|
Takes json data on stdin and evaluates test expressions specified in
|
|
arguments. Each test is evaluated, and output is printed only if the
|
|
test fails. If any test fails the return value of execution will be
|
|
non-zero.
|
|
|
|
EXPR can be one of following types:
|
|
|
|
Value test: test that object in json data found at address is equal to
|
|
specified value:
|
|
|
|
label:address=value
|
|
|
|
Existence test: test that dict or list in json data found at address
|
|
does *not* contain the specified key:
|
|
|
|
label:address!key
|
|
|
|
Extract: extract object from json data found at address and print
|
|
|
|
label:address
|
|
|
|
Results are printed to stdout prefixed by expression label. In all
|
|
cases the test will fail if object does not exist in data.
|
|
|
|
Example:
|
|
|
|
0 $ echo '["a", "b", {"c": 1}]' | python3 json_check_nodes.py 'second_d:[1]="d"' 'no_c:[2]!"c"'
|
|
second_d: value not equal: data[1] = 'b' != 'd'
|
|
no_c: dict contains key: data[2]["c"] = 1
