Tried to open Helix:

helix .

Got:

zsh: command not found: helix

That's because the command to open it is:

hx

Cause writing "helix" is way too many keystrokes! 😜

Themes: https://docs.helix-editor.com/themes.html

mkdir -p ~/.config/helix/themes
hx ~/.config/helix/themes/sonokai

paste the contents of: https://raw.githubusercontent.com/CptPotato/helix-themes/main/schemes/sonokai

then:

wq!

And then in the editor you're in:

:theme sonokai

After:

Pretty straightforward to add a different theme. ✅

[nelsonic]

Almost any VIM theme works.

[nelsonic]

There are already quite a few themes built-in. Select a new one by typing :theme

To test-drive all the themes in: https://github.com/CptPotato/helix-themes

cd /tmp
git clone git@github.com:CptPotato/helix-themes.git
cp -r ./helix-themes/schemes/* ~/.config/helix/themes/

[nelsonic]

e.g: :theme everforest_dark

I can see this becoming my default/goto editor; it has everything I need and is very fast. A couple of annoyances but nothing major. The biggest barrier to entry is memorising the commands / shortcuts. Think I'm going to have to make a video about this.

Just lost some work when accidentally quit Helix 😢 Went looking for auto-save and found: https://docs.helix-editor.com/master/configuration.html Created the ~/.config/helix/config.toml file with the following contents:

theme = "onedark"

[editor]
line-number = "relative"
mouse = false

[editor.cursor-shape]
insert = "bar"
normal = "block"
select = "underline"

[editor.file-picker]
hidden = false

auto-save = true

Got the following error:

Bad config: unknown field `auto-save`, expected one of `hidden`, `follow-symlinks`, `parents`, `ignore`, `git-ignore`, `git-global`, `git-exclude`, `max-depth` for key `editor.file-picker` at line 12 column 1
Press <ENTER> to continue with default config

That's because my auto-save = true was in the "wrong" part of the file ... 🙄 It needed to be in the [editor] section to be parsed correctly. (lame...)

This worked:

theme = "onedark"

[editor]
line-number = "relative"
mouse = false
auto-save = true

[editor.cursor-shape]
insert = "bar"
normal = "block"
select = "underline"

[editor.file-picker]
hidden = false

Back to work. 🧑‍💻
