TIL: Insert Macros for the Helix Editor
I’ve been using the Helix editor for two weeks now as my daily driver in my personal coding projects.
Helix is a modern terminal text editor that’s quite capable as a tool for writing code.
A Kakoune / Neovim inspired editor, written in Rust.
Features
- Vim-like modal editing
- Multiple selections
- Built-in language server support
- Smart, incremental syntax highlighting and code editing via tree-sitter
After some initial bumps in the road due to my Vim muscle memory, I have grown quite fond of Helix. For my pet projects (TypeScript) it works well.
The language server support is great. It offers me the convenience I am used to from other editors (IntelliJ) - auto-complete functionality, hover information and so forth.
Helix is not a fully-fledged IDE, but it doesn’t aim to be one. It is supposed to be an alternative to Kakoune or Vim/NeoVim.
Insert Macros
My NeoVim config sports an “insert macro” for the fat arrow (=>). When I type ‘hsr’ in insert mode, the editor automatically replaces these three characters with a fat arrow (hashrocket).
Here is how the key mapping looks in Vim:
# custom/keymappings.vim
inoremap hsr =>
And the same config in lua (NeoVim):
vim.api.nvim_set_keymap('i', 'hsr', '=>', { silent = true, noremap = true }),
This can also be achieved in Helix:
# ~/.config/helix/config.toml
h = { s = { r = ["normal_mode", ":insert-output echo '=>'", "collapse_selection", "insert_at_line_end"] } }
