Inside python code

View json file

import pyjsonviewer

pyjsonviewer.view_data(json_file="dat/list.json")

JSON data tree will be shown.

View json object

import pyjsonviewer
json_object = {"a":[1,2,3], "b":"test"}
pyjsonviewer.view_data(json_data=json_object)

JSON data tree will be shown.

Vimrc setting

If you are a vim user, you can set this command in your vimrc.

"JSON format
function! JsonFormat()
	%!python -m json.tool
endfunction
command! JsonFormat :call JsonFormat()

"JSON viewer
function! JsonViewer()
	"%!python -m pyjsonviewer -f % > /dev/null
	let filename = expand('%')
	let s:job = job_start(
	\   ["/bin/sh", "-c", "python -m pyjsonviewer -f".filename],{})
endfunction
command! JsonViewer :call JsonViewer()

When you are editing a json file with vim,

you can open it using PyJSONViewer with

: JSONViewer()

You can also format json file with

: JSONFormat()

Open a link with a browser

If a URL is included in a json file,

you can open it with a browser with double click the URL.

pyjsonviewer's Issues

object has no attribute w

Traceback (most recent call last):
File "pyjsonviewer.py", line 299, in
main()
File "pyjsonviewer.py", line 255, in main
root.tk.call('wm', 'iconphoto', root.tk.w,
AttributeError: '_tkinter.tkapp' object has no attribute 'w'

This issue is fixed for me by changing root.w to root at pyjsonviewer.py:255

Installation error: VERSION.py must be VERSION.

VERSION file not found - Cannot install

Hello,
I am installing PyJSONViewer via the following command
pip install --proxy <MYPROXY> PyJSONViewer

The error says that VERSION file is missed: actually it does not seem to be packed up (checked via tar.gz download)

I am on Win10, using PyCharm and a dedicated Python 3.7 environment created with Miniconda3.
This happens both from the command line and from PyCharm, of course.

Thanks!
Andrea

Update version handling

Add test and CI for multi OS

Adding CUI support

Ref: https://pauljuliusmartinez.github.io/

UTF-8 encoded files not reading; seems to require cp-1252 encoding

Per RFC 8259, §8.1, JSON files are UTF-8 encoded.

However, when I use Japanese characters in my UTF-8 encoded JSON files, the program won't load them.

Exception in Tkinter callback

UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 4251: character maps to <undefined>

This is arguably a problem with the Python decoder, but it can be resolved in source code, with:

raw_bytes = open(path_to_file, "rb").read()
return json.loads(raw_bytes.decode("utf-8"))

Release 1.6.0

A list containing datatypes other than str doesn't work

For the given json file

{
    "character_set_1" : ["1", 2, 3]
}

the non-string elements result in an error

Lists Don't Seem to Work

For example, this input:
[1,2,3]

I'm having the issue of missing /VERSION file in a vanilla install of Python

I have a fresh install of Python 3.8 x64 on Windows 10

I have run pip install pyjsonviewer and it looked good.

I go to run pyjsonviewer and receive error:

PS C:\PYTHON38-64\Lib\site-packages\pyjsonviewer> py .\pyjsonviewer.py
Traceback (most recent calllast):
File ".\pyjsonviewer.py", line 20, in
VERSION = open(os.path.dirname(os.path.abspath(file))+"/VERSION", "r").readline()
FileNotFoundError: [Errno 2] No such file or directory: 'C:\PYTHON38-64\Lib\site-packages\pyjsonviewer/VERSION'

Make pyjsonviewer callable from python code.

Expectation: Ability to visualise json files as well as directly load json objects from within python code.

Drag and drop support

Running on Windows from Command Line

Running on Windows from the command line, doesn't work.

To get it to run, I had to execute the following:

import pyjsonviewer.pyjsonviewer
pyjsonviewer.pyjsonviewer.main()

I think this could be solved in the setup.py file by using the console_scripts Entry Point per this documentation.

It's possible that it's as simple as adding this code to setup.py:
entry_points = {'console_scripts': ['pyjsonviewer=pyjsonviewer.pyjsonviewer:main']}

Add GitHub CI settings for unittests.

Installation error: icon.py is .png

add Download badge in REAME.md

list under second layer should be expanded as trees.

Ref: #32 (review)

Cannot open files that do not end with ".json"

I'd like there to be the capacity to read not only ".json" files, but to be able to select also to select from ALL files.

For example, Chrome bookmarks are stored in a file called "Bookmarks" as JSON, but it can't be opened, without copying the file to a temporary directory, and renaming the copy.

v1.4.0

fuzzy search for json item

Need support for list data.

Example :

[  
   {
        "date": "2017-01-01",
        "title": "Automated question answering system using ontology and semantic role",
        "doc_id": "258cc0fd7973def42234f3db5ffdfd2a",
    },
    {
        "date": "2011-01-01",
        "title": "A new fuzzy-based method to weigh the related concepts in semantic focused web crawlers",
        "doc_id": "71ae01c53f4eeb7d402f5bcfbce36f9f",
     }
]

release v1.5

add how to use incremental search in README

release v1.3.0

PyPi registration

Long fields are not accessible beyond window width.

Either long text fields should be wrapped(preferably) or there should be horizontal scrollbar to access fields that are longer than the window width.

Unable to open JSON file in pwd

Installed using pip3 install pyjsonviewer — Received a _tkinter error and resolved that using brew install python-tk

I have a .json file located in a directory (pwd) — repos/data_objects/exported.json

When I run python3 pyjsonviewer -f exported.json OR python3 pyjsonviewer -f repos/data_objects/exported.json I get the same error.

(14:52:30)──> python3 pyjsonviewer -f exported.json                                               2 ↵ ──(Tue,Oct11)─┘
/opt/homebrew/bin/python3: can't open file '/Users/username/repos/data_objects/pyjsonviewer': [Errno 2] No such file or directory

AND

(14:51:19)──> python3 pyjsonviewer -f ~/repos/data_objects/exported.json                       2 ↵ ──(Tue,Oct11)─┘
/opt/homebrew/bin/python3: can't open file '/Users/username/repos/data_objects/pyjsonviewer': [Errno 2] No such file or directory

After installing python-tk with brew (brew install python-tk) running $ pyjsonviewer spawns a tree nav pane, as expected.

/opt/homebrew/lib/python3.10/site-packages/pyjsonviewer/pyjsonviewer.py start!!

From the pyjsonviewer pane, I'm able to open the file.
