Git Submodules - Basic Explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a sub-repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

Separate big codebases into multiple repositories.

The introduction to Reactive Programming you've been missing

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

To remove a submodule you need to:

Delete the relevant section from the .gitmodules file.
Stage the .gitmodules changes git add .gitmodules
Delete the relevant section from .git/config.
Run git rm --cached path_to_submodule (no trailing slash).
Run rm -rf .git/modules/path_to_submodule (no trailing slash).
Commit git commit -m "Removed submodule "
Delete the now untracked submodule files rm -rf path_to_submodule

Issues with latex math in markdown files, for display on Github Pages (using jekyll)

Our solution: use kramdown parser, with GFM option (Github flavored Markdown). In the .Rmd, use $$ for display math and $ for inline math. then have a script which turns the inline math demarkation in the .md file from $ into $$ when appropriate (avoiding data frame usage), before uploading the .md to Github. This way, RStudio preview looks the same as the Github Pages version.

redcarpet math

doesn't respect $ or $$ (will parse characters within these, such as _), but has workarounds:
has a useful option, no_intra_emphasis, so underscores between ascii characters are not converted to <em> tags, so $x_1$ is fine
need to escape underscores after non-ascii characters, for example $\mathbf{x}\_1$
need to double escape curly bracket: \\{
