Reading and Writing Buffers in Practice - Learning Emacs Lisp #5

In this video, we'll work on a practical example of writing Emacs Lisp to read and write contents of buffers! We continue the work on our dotfiles management package, now called "dotcrafter.el", to add the ability to extract all tangled configuration paths from our Org Mode files and then write out those paths to the '.gitignore' file of the dotfiles repository. We cover the following topics: 0:00 Intro 0:38 Why learn about buffers? 2:15 What will we learn? 5:12 What is a buffer? 7:01 Getting the "current" buffer 8:02 Getting a buffer by name 9:41 Changing the current buffer 10:37 Changing the current buffer safely! 13:55 Working with file buffers 17:36 Example: Getting the buffers for our configuration Org files 20:38 Loading a file into a buffer 22:27 Example: Getting or creating the Org file buffer 24:44 What's the point? 28:21 Moving the point 32:45 Preserving the point 33:41 Examining buffer text 36:26 The Thing (thing-at-point) 39:45 Searching for text 43:24 Example: Finding Org code block output paths 50:02 Inserting text 52:00 Example: Updating the .gitignore file 57:31 Deleting text 58:31 Saving a buffer 59:09 Example: Cleaning up and saving the .gitignore file 1:00:35 What's next? 1:01:50 Sponsors and outro The package code from this episode can be found here: https://github.com/daviwil/dotcrafter...
