## Install or Update
|
||
|
||
After deploying this nix flake, run the following command to install or update emacs:
|
||
|
||
```bash
|
||
doom sync
|
||
```
|
||
|
||
when in doubt, run `doom sync`!
|
||
|
||
## Notes
|
||
|
||
1. we can run any emacs command via `M-x`(Alt + x).
|
||
|

## Why emacs?
|
||
|
||
1. Explore the unknown, just for fun!
|
||
2. Org Mode

Here is the cheetsheet related to my DoomEmacs configs. Please read vim's common cheetsheet at [../README.md](../README.md) before reading the following.
|
||
|
||
### Basics
|
||
|
||

|
||

||

|
||
| Popup Terminal(vterm) | `SPC + o + t` |
|
||

|
||
### Window Navigation
|
||
|
||

|
||

|
||

|
||
| Close the current window | `SPC w q` |
|
||
| Rebalance all windows | `SPC w =` |
|
||
| Set window's width(columns) | `80 SPC w \|` (the Vertical line is escaped due to markdown's limits) |
|
||
| Set window's height | `30 SPC w _ ` |
|
||
|
||

Use `-`, `+` to resize the image, `r` to rotate the image.
|
||
|

### Search & replace
|
||
|
||
```bash
|
||
SPC s p foo C-; E C-c C-p :%s/foo/bar/g RET Z Z
|
||
```
|
||
|
||
1. `SPC s p`: search in project
|
||
1. `foo`: the keyword to search
|
||
1. `C-; E`: exports what you’re looking at into a new buffer in grep-mode
|
||
1. `C-c C-p` to run wgrep-change-to-wgrep-mode to make the search results writable.
|
||
1. `:%s/foo/bar/g RET`: replace in the current buffer(just like neovim/vim)
|
||
1. `Z Z`: to write all the changes to their respective files
