Como embelezar JSON em Python?

Alguém pode sugerir como posso embelezar JSON em Python ou por meio da linha de comando?

O único embelezador JSON online que poderia fazer isso era: http://jsonviewer.stack.hu/ .

Preciso usá-lo de dentro do Python, no entanto.

Este é meu conjunto de dados:

Na linha de comando:

echo '{"one":1,"two":2}' | python -mjson.tool

que produz:

{
    "one": 1, 
    "two": 2
}

De forma programática, o manual Python descreve JSON de impressão bonita :

>>> import json
>>> print json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
{
    "4": 5,
    "6": 7
}

Use o indentargumento da dumpsfunção no módulo json .

Dos documentos:

>>> import json
>>> print json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
{
    "4": 5,
    "6": 7
}

Uma solução in-python mínima que colore os dados json fornecidos por meio da linha de comando:

import sys
import json
from pygments import highlight, lexers, formatters

formatted_json = json.dumps(json.loads(sys.argv[1]), indent=4)
colorful_json = highlight(unicode(formatted_json, 'UTF-8'), lexers.JsonLexer(), formatters.TerminalFormatter())
print(colorful_json)

Inspirado no pjsonmencionado acima. Este código precisa pygmentsser instalado.

Exemplo de saída:

Experimente o underscore-cli :

cat myfile.json | underscore print --color

É uma ferramenta muito bacana que pode fazer muita manipulação de dados estruturados de maneira elegante, executar snippets js, preencher modelos, etc. É ridiculamente bem documentada, polida e pronta para uso sério. E eu escrevi. :)

O comando cli que usei com o python para isso é:

cat myfile.json | python -mjson.tool

Você deve encontrar mais informações aqui:

http://docs.python.org/library/json.html

Parece que o jsbeautifier abriu o código-fonte de suas ferramentas e as empacotou como bibliotecas Python e JS e como ferramentas CLI. Não parece que eles chamam um serviço da web, mas não verifiquei muito de perto. Consulte o repositório github com instruções de instalação.

De seus documentos para Python CLI e uso de biblioteca:

Para embelezar usando python:

$ pip install jsbeautifier
$ js-beautify file.js

A saída embelezada vai para stdout.

Para usar jsbeautifiercomo biblioteca é simples:

import jsbeautifier
res = jsbeautifier.beautify('your javascript string')
res = jsbeautifier.beautify_file('some_file.js')

... ou, para especificar algumas opções:

opts = jsbeautifier.default_options()
opts.indent_size = 2
res = jsbeautifier.beautify('some javascript', opts)

Se você quiser passar uma string em vez de um nome de arquivo e estiver usando o bash, poderá usar a substituição de processo da seguinte maneira:

$ js-beautify <(echo '{"some": "json"}')

Eu não gostei da saída de json.dumps (...) -> Para o meu gosto muitas novas linhas. E eu não queria usar uma ferramenta de linha de comando ou instalar algo. Eu finalmente encontrei pprint do Pythons (= impressão bonita). Infelizmente, ele não gera JSON adequado, mas acho que é útil ter um símbolo amigável nos dados armazenados.

Saída de json.dumps(json_dict, indent=4)

Uso de pprint:

import pprint

json_dict = {"hyperspace": {"constraints": [], "design": [["windFarm.windparkSize.k", "continuous", [0, 0, 5]], ["hydroPlant.primaryControlMax", "continuous", [100, 300]]], "kpis": ["frequency.y", "city.load.p[2]"]}, "lhc_size": 10, "number_of_runs": 10}

formatted_json_str = pprint.pformat(json_dict)
print(formatted_json_str)
pprint.pprint(json_dict)

Resultado de pprint.pformat(...)ou pprint.pprint(...):

{'hyperspace': {'constraints': [],
                'design': [['windFarm.windparkSize.k', 'continuous', [0, 0, 5]],
                           ['hydroPlant.primaryControlMax',
                            'continuous',
                            [100, 300]]],
                'kpis': ['frequency.y', 'city.load.p[2]']},
 'lhc_size': 10,
 'number_of_runs': 10}

alias jsonp='pbpaste | python -m json.tool'

Isso imprimirá muito bem o JSON que está na área de transferência do OSX. Basta copiá-lo e, em seguida, chamar o alias de um prompt Bash.

Você pode canalizar a saída para jq. Se você python script contém algo como

print json.dumps(data)

então você pode disparar:

python foo.py | jq '.'

Use a biblioteca de ferramentas Python

Linha de comando: python -mjson.tool

No código: http://docs.python.org/library/json.html

Primeira instalação de pigmentos

então

echo '<some json>' | python -m json.tool | pygmentize -l json

Seus dados estão mal formados. Os campos de valor, em particular, têm vários espaços e novas linhas. Os formatadores automatizados não funcionarão nisso, pois não modificarão os dados reais. Conforme você gera os dados para saída, filtre-os conforme necessário para evitar os espaços.

Com jsonlint (como xmllint):

aptitude install python-demjson
jsonlint -f foo.json
