Python 2 json.dump() file-like object class for tab indenting of output file

Using json.dump() with Python 2, indent argument is limited to number of spaces only - no ability for tabs use.

Class JSONTabIndentFileWriter provides a file-like object which will rewrite json.dump() output indending from spaces to tabs.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

GlideRecord & GlideAggregate Cheat Sheet ❗

GlideRecord(String tableName) ❗

var gr = new GlideRecord('incident'); // use the incident table
gr.query(); // fetch data from the database
while (gr.next()) { // advance
    gs.info(gr.short_description);

Console output too chatty?
Set com.glide.util.Log.developer_filter = true to cut down on non-interactive console log entries such as scheduled workers. (Don't forget to remove it when you're done!)

A lot of people mentioned other immutable JS libraries after reading my post. I thought it would be good to make a list of available ones.

There are two types of immutable libraries: simple helpers for copying JavaScript objects, and actual persistent data structure implementations. My post generally analyzed the tradeoffs between both kinds of libraries and everything applies to the below libraries in either category.

Libraries are sorted by github popularity.
