* Episode 2 - Survive on the first day
|
||||
** Why bother?
|
||||
** Why GNU/Emacs?
|
||||
*** People might say because of
|
||||
- Org-mode
|
||||
- LSP support
|
||||
- Support for many many languages
|
||||
- It's lightweight
|
||||
- Tons of plugins
|
||||
- ...
|
||||
*** I'd say
|
||||
- Coz it's a lisp environment with an editor attached to it
|
||||
- Lisp is the difference
|
||||
+ It's super easy to extend/hack emacs
|
||||
+ In compare to other editors
|
||||
- You can do pretty much whatever your like in ELisp
|
||||
- It's like a framework for building an editor
|
||||
|
||||
** FAQ
|
||||
*** What is the difference between Doom, Spacemacs, FG42 and ...?
|
||||
Different editors based on Emacs
|
||||
*** Which one should I use?
|
||||
*** How to install Emacs packages?

** UI Basics & Basic Concepts
|
||||
- Window
|
||||
- Frame
|
||||
- Mode line
|
||||
- Buffers
|
||||
- Mini buffer/Echo area
|
||||
- Point
|
||||
- Major mode
|
||||
- Minor mode
|
||||
|
||||
** Basic Keybindings
|
||||
How to read key bindings? Here is an example =C-x M-e 4=, it means press =x= key while
|
||||
holding =Control= and then press =e= key while pressing down =Alt= and finally press =4=.
|
||||
|
||||
- Emacs tutorial =C-h t= (or https://www.gnu.org/software/emacs/tour/)
|
||||
- Quit emacs =C-x C-c=
|
||||
- Abort =C-g=
|
||||
- Get Help =C-h= family
|
||||
+ =C-h f=
|
||||
+ =C-h v=
|
||||
+ =C-h m=
|
||||
+ =C-h k=
|
||||
+ =C-h a=
|
||||
|
||||
- Run a command (function) =M-x=
|
||||
- Visit a file =C-x C-f=
|
||||
- Search in Buffer =C-s=
|
||||
- Save buffer =C-x C-s=
|
||||
- Select region =C-SPC=
|
||||
- Copy =M-w=
|
||||
- Cut(killing) =C-w=
|
||||
- Paste(yanking) =C-y=
|
||||
- Kill buffer =C-x k=
|
||||
- Switch buffer =C-x b=
|
||||
- Undo =C-/=
|
||||
- Eval expression =C-x C-e=
|
||||
- =describe-mode=

||||
** Lisp basics
|
||||
- Expressions everywhere
|
||||
- Code a data structure
|
||||
- Almost everything in Lisp evaluates to themselves except:
|
||||
+ lists
|
||||
+ Symbols
|
||||
+ ...
|
||||
- Lisp laws:
|
||||
1. Everything in Lisp is an expression and evaluation of an expression
|
||||
means replacing it with its value
|
||||
|
||||
2. Almost everything in Lisp evaluates to themselves except:
|
||||
- Lists
|
||||
- Symbols
|
||||
- Quotes
|
||||
- ...
|
||||
-
|
||||
3. List evaluation
