WARNING: Bad code. I found this on my old computer and thought it was interesting to see my parsing before I knew any parsing. I was 16 and teaching myself C++ for the first time when I wrote this.

A primer/tutorial on the theory and practice regular expressions

Regular Expressions

In theory:

  • Regular expressions define a set of strings called the Language
    • If a string matches the regular expression, it's in the language set
  • There are only three operations (because math strives to be minimal)
    • Concatenation - "a concatenated with b" is just ab
    • Or - written a|b. In most regex libraries
    • Klenee Star - zero or more of the expression it's applied to; writtena*

How to merge multiple git repos into one repo, and preserve history

Merging multiple git repos into one

tl;dr:

  1. Import other repos as branches
  2. Move the files in the other repos into subdirectories for each project
  3. Rebase the other repo branches onto the master
  4. Merge everything into master in order

Note: placeholders are in angle brackets.
