  • Questions
  • Is being in Evil mode going to make this more challenging?
  • [ ]
  • Big points
  • Emacs has been around for a long time
  • Extensibility
  • Tinker's editor
  • A good way to learn Lisp, in an interpreter that is written in Lisp.

  • Quotes =Vim users are migrating to Emacs because, well, Emacs is often a better Vim than Vim.=

  • Resources

  • Things to remember:
  • Keyboard shortcuts
  • C-x C-f -> open file
  • C-x C-s -> save file
  • C-x k -> close buffer
  • C-x b -> create a new buffer
  • C-x C-e -> Evaluate expressions
  • C-c C-d C-d -> Display documentation
  • Spc-f-r -> recent files
  • Spc-. -> open file
  • C-x C-e runs last expression
  • C-c C-k compiles the code
    • C-u C-x C-e runs last expression in line.
  • Chapter 3 ##Things to remember =If Emacs is giving you error messages when you start it, youcan use-qto prevent yourinit filefrom loading.=

=Emacs will typically startslower than other editors (as it has a lot more packages andfeatures) as itā€™s designed for long-running sessions and notquick edits.=

Caps Lock as Control

I'm using Keyboard Maestro and Karabiner to rebind my keys.

M-x - pronounced mex or M x

I use Alfred and had remapped Spotlight to be option space. That meant I couldn't use M-Spc. Turned that off.

Customize interface

I find it a bit overwhelming - I think I prefer tinkering with code for now.

Evaluating Elisp

M-x eval-buffer M-x eval-region (defn test [] (- 3 4)) ielm

Package management

Comes from a few different places but combined by Emacs

**- The C-x C-x command (called exchange-point-and-mark ) is in- teresting. It reactivates the region from point ā€“ which is your current location in the buļ¬€er ā€“ and wherever the mark is; then, it swaps the point and mark positions. This com- mand is especially useful if you want to reactivate the last region or if you simply want to swap the position of mark and point.

ā€œOur technologies can be divided, roughly, into four categories, according to the way they supplement or amplify our native capacities. One set, which encompasses the plow, the darning needle, and the fighter jet, extends our physical strength, dexterity, or resilience. A second set, which includes the microscope, the amplifier, and the Geiger counter, extends the range or sensitivity of our senses. A third group, spanning such technologies as the reservoir, the birth control pill, and the genetically modified corn plant, enables us to reshape nature to better serve our needs or desires. The map and the clock belong to the fourth category, which might best be called, to borrow a term used in slightly different senses by the social anthropologist Jack Goody and the sociologist Daniel Bell, ā€œintellectual technologies.ā€

Our technologies extend and expand our wills - we can dig for longer and deeper with shovels and then JCBs, we can perceive more with magnifying lenses and then microscopes, we can shape and control our environment and bodies with fans, AC and medication and finally we have tools which help us extend, expand our supplement our intellectual capacities.
