是否有(Unix)shell脚本将JSON格式化为可读格式?
基本上,我希望它转换以下内容:
{ "foo": "lorem", "bar": "ipsum" }
…变成这样:
{
"foo": "lorem",
"bar": "ipsum"
}

你可以用西德尔。
Xidel是一个命令行工具,可以使用CSS、XPath 3.0、XQuery 3.0、JSONiq或模式模板从HTML/XML页面或JSON API下载和提取数据。它还可以创建新的或转换的XML/HTML/JSON文档。
默认情况下,Xidel漂亮打印:
$ xidel -se '$json' <<< '{"foo":"lorem","bar":"ipsum"}'
{
"foo": "lorem",
"bar": "ipsum"
}
or:
$ echo '{"foo":"lorem","bar":"ipsum"}' | xidel -se '$json'
{
"foo": "lorem",
"bar": "ipsum"
}

使用Node.js的单线解决方案如下所示:
$ node -e "console.log( JSON.stringify( JSON.parse(require('fs').readFileSync(0) ), 0, 1 ))"
例如:
$ cat test.json | node -e "console.log( JSON.stringify( JSON.parse(require('fs').readFileSync(0) ), 0, 1 ))"

from __future__ import unicode_literals
from __future__ import absolute_import
from __future__ import print_function
from __future__ import division
import json
import jsonschema
def _validate(data):
schema = {"$schema": "http://json-schema.org/draft-04/schema#"}
try:
jsonschema.validate(data, schema,
format_checker=jsonschema.FormatChecker())
except jsonschema.exceptions.ValidationError as ve:
sys.stderr.write("Whoops, the data you provided does not seem to be " \
"valid JSON.\n{}".format(ve))
def pprint(data, python_obj=False, **kwargs):
_validate(data)
kwargs["indent"] = kwargs.get("indent", 4)
pretty_data = json.dumps(data, **kwargs)
if python_obj:
print(pretty_data)
else:
repls = (("u'",'"'),
("'",'"'),
("None",'null'),
("True",'true'),
("False",'false'))
print(reduce(lambda a, kv: a.replace(*kv), repls, pretty_data))
下面是Groovy的一行代码:
echo '{"foo": "lorem", "bar": "ipsum"}' | groovy -e 'import groovy.json.*; println JsonOutput.prettyPrint(System.in.text)'
$ sudo apt-get install edit-json
$ prettify_json myfile.json
多亏了J.F.Sebastian非常有用的指导,我想出了一个稍微增强的脚本:
#!/usr/bin/python
"""
Convert JSON data to human-readable form.
Usage:
prettyJSON.py inputFile [outputFile]
"""
import sys
import simplejson as json
def main(args):
try:
if args[1] == '-':
inputFile = sys.stdin
else:
inputFile = open(args[1])
input = json.load(inputFile)
inputFile.close()
except IndexError:
usage()
return False
if len(args) < 3:
print json.dumps(input, sort_keys = False, indent = 4)
else:
outputFile = open(args[2], "w")
json.dump(input, outputFile, sort_keys = False, indent = 4)
outputFile.close()
return True
def usage():
print __doc__
if __name__ == "__main__":
sys.exit(not main(sys.argv))
