I have 174 markdown documents in total on this blog, and ideally I would like to be able to spellcheck them all and automate the process in such a way that my deploy script will flag errors and refuse to deploy if a spelling error is found. I could create a custom word list for aspell and add thousands of custom words to it, but I would probably still run into many more false positives in the future. I knew there were probably other errors in my blog posts that were not in my list, so I decided to compile a list of all unique words present in all of my past blog posts, sort it, and write it to a text file so that I could visually inspect everything.
