/*
* DataGrip extension to export results to markdown.
* The markdown table format is supported by Github and Jira.  I haven't tested others.
* 
* Tested on DataGrip 2016.2.2
* - Open the File view.  View -> Tool Windows -> Files
* - Activate the "Scratches" tab.  You should see "Files", "Scopes", and "Scratches".
* - Copy this file to Extensions/Database Tools and SQL/data/extractors/Markdown.JavaScript.md.js
* - Run a query with some results.
* - Change the export format to Markdown.JavaScript.md.js and click "To Clipboard".

Installing tmux-256color for macOS

• macOS 10.15.5
• tmux 3.1b

macOS has ncurses version 5.7 which does not ship the terminfo description for tmux. There're two ways that can help you to solve this problem.

The Fast Blazing Solution

Instead of tmux-256color, use screen-256color which comes with system. Place this command into ~/.tmux.conf or ~/.config/tmux/tmux.conf(for version 3.1 and later):

# This is the URL we want:

# First, the route. 
#
# "model" is the name of the active storage model that has the preview.
# "classification" and "identifier" are together a unique key for the records.

Add the following to application.rb:

$icallbacks = []
$icallbacks.define_singleton_method(:print) do
  puts sort_by { |(a, b)| -b }.map { |(a, b)| "#{b}\t\t#{a}" }.join("\n")
end

ActiveSupport::Notifications.subscribe("load_config_initializer.railties") do |event|
 $icallbacks << [event.payload[:initializer], event.duration]

For years, people have been using jemalloc with ruby. There were various benchmarks and discussions. Legend had it that Jemalloc 5 didn't work as well as Jemalloc 3.

Then, one day, hope appeared on the horizon. @wjordan offered a config for Jemalloc 5.
