How to combine two git repositories.

Combining two git repositories

Use case: You have repository A with remote location rA, and repository B (which may or may not have remote location rB). You want to do one of two things:

  • preserve all commits of both repositories, but replace everything from A with the contents of B, and use rA as your remote location
  • actually combine the two repositories, as if they are two branches that you want to merge, using rA as the remote location

NB: Check out git subtree/git submodule and this Stack Overflow question before going through the steps below. This gist is just a record of how I solved this problem on my own one day.

Before starting, make sure your local and remote repositories are up-to-date with all changes you need. The following steps use the general idea of changing the remote origin and renaming the local master branch of one of the repos in order to combine the two master branches.

A fishbone editor
  • Make a bulleted Markdown list in the top left to update the list
  • Press edit to hide the editor
  • Press save to use [SVG Crowbar][crowbar] to save a copy
  • Click to drag nodes

This is an integration of [this implementation][orig] of a [Fishbone or Ishikawa][ish] diagram, which shows contributions of different levels of a hierarchy to a main concept, with a Markdown editor for making quick diagrams.

The diagram is implemented in [d3.js][d3], while rich-text editing is provided by [CodeMirror][cm], and [marked][mkd] handles Markdown processing.

How to hide <select> dropdown's arrow in Firefox when using "-moz-appearance: none;".

This is no longer a bug. I'm keeping the gist for historical reasons, as it helped to get it fixed. Make sure to read the notes by the end of the post.

How to remove hide the select arrow in Firefox using -moz-appearance:none;

TL;DR (or, the fix)

  1. Set -moz-appearance to none. This will "reset" the styling of the element;
  2. Set text-indent to 0.01px. This will "push" the text a tiny bit[1] to the right;
