Look Back by Tatsuki Fujimoto is about a young girl in fourth grade who is proud of her role as the manga artist in her class newspaper.
Another classmate, a recluse that avoids school sends in their artwork and she's stunned to discover it is significantly better than her own.
She works harder and her artwork improves but her social life suffers but when she sees another example of her reclusive classmate's work she realizes it's hopeless and gives up.
At the end of the year her teacher asks her to take something to the home of this reclusive classmate. She objects at first but then goes to her classmate's house and slips a quickly scribbled little comic about wanting her to come out under the door. As she's leaving her classmate comes running out and confronts her.
Her classmate says as soon as she saw the scribbled cartoon she she knew who it was, that she's a big fan, and she's been eagerly reading her comics over the years. Stunned by this news, she lies and tells the reclusive girl the reason she stopped drawing is because she was working on a big idea for a contest.
The next few panels are the reason I'm making this post. This girl was proud of her skills, crushed by the realization there are others with greater talent, had given up, and then her pride dragged her back in. The panels following this revelation don't have any dialog but you can see her anguish and pride.
The plot continues but this really is the moment that makes the whole comic shine. The artist behind this one-shot, Tatsuki Fujimoto is the same artist that did chainsaw man.

There's currently no official support for spellchecking in helix but it supports the LSP protocol and there are tools that will provide spelling and grammar checking over LSP. I've setup my editor to use ltex-ls. It's slow (written in java) and it won't actually fix the spelling but it's better than nothing until we get official support. Here's how I set it up.
Start by downloading and unzipping the application.
Then modify your .config/helix/languages.toml with this (using your path to the ltex-ls binary):
[[language]]
name = "markdown"
language-servers = [{ name = "ltex"}]
soft-wrap.enable = true
soft-wrap.wrap-indicator = ""
# scope = "source.markdown"
file-types = ["md", "txt", "tex"]
[language-server.ltex]
command = "/home/na/app/ltex-ls/bin/ltex-ls"
Restart helix and it should automatically start loading the LSP (you'll see a spinner in the status bar).
By default ltex-ls is set for american english but you can set other langues like this.
This was taken from a blog post that talks about setting up a note taking app in helix.

This is cool and the existing documentation isn't super clear. I wanted to debug some unit tests in a script I was writing. Rust provides a gdb debugger with the ability to pretty print rust objects called rust-dbg. Run it from the command line like normal with:
rust-gdb target/debug/rename_files
Unfortunately unit tests like this:
#[cfg(test)]
mod tests {
use super::*;
#[test]
fn crop_start() {
let filename = "1234567890";
let newfilename = crop_filename(filename, 1, 0, false).expect("failed to crop");
assert_eq!("234567890".to_string(), newfilename);
}
#[test]
fn crop_end() {
aren't normally compiled and linked into your binary but you can get a path to this binary with 'cargo test':

Unfortunately this only gives you raw gdb connection and I couldn't get -tui to work but you can do your debugging directly in the helix editor. To get started configure your system.
In my case I ran:
sudo pacman -S lldb
cd /usr/local/etc
sudo helix lldb_vscode_rustc_primer.py
and pasted this into that file:
import subprocess
import pathlib
import lldb
# Determine the sysroot for the active Rust interpreter
rustlib_etc = pathlib.Path(subprocess.getoutput('rustc --print sysroot')) / 'lib' / 'rustlib' / 'etc'
if not rustlib_etc.exists():
raise RuntimeError('Unable to determine rustc sysroot')
# Load lldb_lookup.py and execute lldb_commands with the correct path
lldb.debugger.HandleCommand(f"""command script import "{rustlib_etc / 'lldb_lookup.py'}" """)
lldb.debugger.HandleCommand(f"""command source -s 0 "{rustlib_etc / 'lldb_commands'}" """)
Finally I updated my languages.toml file with:
[[language]]
name = "rust"
[language.debugger]
name = "lldb-vscode"
transport = "stdio"
command = "lldb-vscode"
[[language.debugger.templates]]
name = "binary"
request = "launch"
completion = [ { name = "binary", completion = "filename" } ]
args = { program = "{0}", initCommands = [ "command script import /usr/local/etc/lldb_vscode_rustc_primer.py" ] }
I reloaded my config with ':config-reload' and then in helix I used '<Space> g' to bring up the debugger menu and 'b' to set a breakpoint on a particular line of code (in my unit test).
Then 'l <Enter>' to tell it to run a binary in the debugger and I gave it the path to the compiled binary with linked in unit tests:
And that's it. It automatically ran the script, stopped at my breakpoint and let me inspect values. It's still primitive but having this all already built into the editor without any plugins or super weird configuration is nice.
Since my last post in July I've made the jump to helix as my primary editor for code. They still haven't addressed most of the things that bothered me last year but I've been writing more rust code and the rust-analyzer support in helix is just better than neovim.
Unfortunately it took hours to get this working. As it turned out:
helix --health
lies. It told me I was all good to go but rust-analyzer wasn't actually installed. I still needed to run:
rustup component add rust-analyzer
On my main system I also needed to remove an old version of rust-analyzer that was in my ~/.local/bin/ (found with 'which rust-analyzer' and 'rustup which rust-analyzer').
Before I discovered the missing rust-analyzer I went through every configuration option to make sure I didn't miss an enable switch and I revisited my theme to make sure it was working but the text wasn't visible. There was also conflicting information on whether I needed to add stuff to the language.toml file. The changes I'd made were for older versions of helix and were no longer necessary. You can see my final helix configuration in my dotfiles repo here.)
Now I'm attempting to train my fingers to use this new editor. My config.toml file has the list of aliases I'm trying to remember:
# na's muscle memory
# https://cheatography.com/hiddenmonkey/cheat-sheets/helix/
# https://github.com/helix-editor/helix/wiki/Migrating-from-Vim
# x selects the current line - delete it with xd
# d deletes the current character
# :e # use :o
# reload from disk with :reload
# * # be*n (or preferably Alt+o*n)
# \c # use Ctrl+c
# m is now a jumplist # use Ctrl+s to save and Ctrl+o to return, space+j to view
# :%s/word/replacement/g<ret> # use %sword<ret>creplacement<esc>
# % # use mm instead!
# 0 = "goto_line_start" # use gh instead!
# "$" = "goto_line_end" # use gl instead!
# G = "goto_file_end" # use ge instead!
# ,1 = goto_last_accessed_file # use ga or (Space Space) instead
# can't toggle a render so use two buttons
# can't toggle gutter contents
# can't toggle soft-wrap see languages.toml
# V (select whole line) # use xv to get started
# :reg # not possible https://www.reddit.com/r/HelixEditor/comments/130gbzy/is_it_possible_to_cycle_through_the_yank_history/?rdt=40070
# Y # use :clipboard-yank (or Space y)
# Ctrl+r (redo) # use U
# autocomplete # Ctrl+x
# q and ` # Q and q
# new stuff (multicursor)
# C - duplicate cursor down
# s - select - duplicate cursor horizontally
# ,, - cancel multiple cursors
# & - align vertical cursors
# Alt-s - select all endlines in a block
# S - split on a regex pattern
# Alt+; - put cursor on other end of selection
# ; - drop selection but keep cursors
#
# R - replace a selected word with the contents of the paste buffer
# ms( - add paranthesis around selection
# md( - remove paranthesis from within
I've found the main pain points are 'x', 'd', and 's'.
What this means is that 50+ times a day I type 'dd' to remove a line and discover it only removed two characters. Or I type 'x' to remove a character and have to stop because now the entire line is highlighted. Or I select some text and hit 's' to change it and enter a restricted selection mode.
Just now, typing that last paragraph, I literally made these mistakes six times. Extrapolate that to all the typing I did today and you can imagine the frustration.
Still it seems like the editor has some momentum. They recently added a pipe command and I've been seeing helix users abusing it to do unspeakable things like adding copilot support. And the vifm guys have instructions on how to integrate the file picker into a tmux-helix install using some frightening tmux configuration hacks.
I still use vim for my git commits (and apparently for spellcheck) and I can already tell my muscle memory is soon going to have the opposite problem and I'll start making helix mistakes in neovim. The perils of switching text editors are fraught.
