Package: jsonstrip
ThejsonstripPython moduleThejsonstripremoves comments from a JSON document.
It can  be used as a Python module:import jsonstrip

...
with open(filename, 'r', encoding='utf-8') as file:
    data = json.loads(jsonstrip.strip(file.read()))or as a command line filter:python3 -m jsonstrip < commented.json > regular.jsonWhat makesjsonstripunique is that it preserves line/column position of text.Why do we need to strip comments from JSON?TheJSON specificationdoes not allow comments.
A commented JSON is invalid JSON. This limitation does not matter when computer
programs exchange data, but sometimes an admin needs to write a configuration
or a similar file in JSON format and wants to comment the contents. Those comments
need to be removed before the document can be loaded.Which comment types are recognized?JavaScript (JS) comments - both single line and multi-line -
and since version22.10.20also the widely-used (but not valid in JS) hash sign comments.FeaturesThemain featureis that line/column position of text is preserved.
A hand-edited file may contain mistakes and in case of an error like below,
the exact position can be easily found in the original document and corrected there.json.decoder.JSONDecodeError: Expecting value: line 15 column 40The input document is properly parsed in order not to modify strings that happen
to look like comments:[
/* this is a comment and will be removed */
"but /* this is a string and it will be left untouched */",
"this is // not a line comment"   // the real comment is here
]It comes with ajsoncheckutility described below.Thejsonstripis short, simple, fast, open-source and free.What it doesn't doThe author has decided to keep thejsonstripas simple as possible.Thejsonstripdoes not minimize the JSON document.
It does not strip any unneeded whitespace.Thejsonstripdoes not verify the JSON. It is assumed
that its output will be loaded by a decoder and will be verified there.Thejsonstripdoes not even verify the comments. If a comment is open
with/*, but not properly closed with*/,  the rest of the document
becomes a comment and as such it will be removed without a warning.InstallationInstall withpipfrom the PyPI.How it worksSingle line commentsA single line comment starts either with two forward slashes//or a single hash sign#and continues until the end of a line. Single line comments are removed.Input:[10, 20, // this is a comment and will be removed
30, 40]  # this text is also a commentOutput:[10, 20, 
30, 40]Multi-line commentsA multi-line comment (also called a block comment) starts with/*and ends with*/.
These comments are removed when occurring at the end of line and replaced
by whitespace elsewhere.Input:{"name": "foo", "value": 1001 /* comment */, "flag": true }Output; note the unchanged position of the text:{"name": "foo", "value": 1001              , "flag": true }Note that multi-line comments cannot be nested, the*/sequence
always terminates a comment:/*
 * text
 * text  /* a comment inside a comment (WRONG!) */
 * BEWARE: no longer a comment
 */Thejsoncheckcommand line utilityThis little program reads a commented JSON document, strips the comments
and decodes the resulting JSON to check if there are any errors. JSON objects
(i.e. Python dicts) are checked for duplicate keys. (Note that the standard
Python JSON decoder accepts duplicate keys and each occurrence overwrites
the previous one. That makes some errors difficult to spot.)The result is printed on the standard output, one line for each input file.Usage# without arguments it reads from the stdin:
some-program | jsoncheck

# with arguments it checks the named files:
jsoncheck filename1 [filename2 ...]Exit code0 = all input files are OK1 = invalid JSON in some input file(s)2 = I/O error reading some input file(s)3 = both errors 1 and 2 occurred
