So I recently switched my editor to Vim (last month to be exact), I will probably post my experience sometime later on. If you are interested I am documenting my vim journey (or cheatsheet) here.
Let me show you how to combine the 3 most powerful tools I use in my daily workflow to achieve this. Note that this post is only for users who are on *nix environments because they probably have Bash, Python & Vim installed anyways.
So the heavy lifting is done by Python’s JSON CLI tool
$ python3 -m json.tool ugly.json
This will print the JSON files in a nice readable format, you can also sort key using the --sort-keys
argument
Ok then that’s settled we now just need to redirect the output to the same file. Let’s write a small bash function to make this portable. Open your .bashrc
or .bash_functions
& put this bad boy in!
pj() {
# prettify json using python3
if [[-z "$1"]]; then
echo "No file path"
exit 1
fi
pretty_json=$(python3 -m json.tool "$1") && echo "$pretty_json" > "$1"
}
Cool, now you can just do pj ugly.json
to do the work.
If you had like an in-editor solution, all you need to do is add this in your vimrc
or init.vim
:command Pretty !pj %:p
This will create a Vim Ex
command called Pretty which invokes our external bash function. %:p
gives us the full path of the file in the buffer.
That’s it, Everything is Sexy now. Invoke the :Pretty
command on your current buffer & pj
will do its job.
Always know your tools. Master the fuck outta them!
What’s the use if I have a plugin?
Well, I love plugins too but I know this is a very simple thing to do & can be easily achieved using things I already know, so why install an external plugin?
Wait not everything is lilies and roses. This might not be very efficient for large JSON files. Let me know if the reader finds a better way to do it.
