there is a pr that properly redraws thats waiting on another review helix-editor/helix#6949 , best bet right now to redraw the screen is to preview a theme

@VuiMuich i get this same thing happening non my work MacBook (M2), but it doesn’t happen on my personal intel MacBook.

What are you running? I also tried with different terminal emulators and they all produced the same result on my M2 MacBook.

I am on Manjaro Linux with Alacritty, but also tried wezterm, shell is actually nushell but my efforts translating the script to nu was without effort, it seems that some of the redirecting bash and fish are doing with stdout does work to fundamentally different for that to work.

Windows version for PowerShell

config.toml

A-f = [":theme dark_plus"]
C-f = [":new",":insert-output pwsh C:\\Users\\<some-path>\\bin\\lfp.ps1","split_selection_on_newline","goto_file","goto_last_modification","goto_last_modified_file",":buffer-close!",":theme default"]

lfp.ps1

# lf pick (lfp) for helix primarily and lf integration
lf -selection-path=C:\Users\<user>\AppData\Local\Temp\lf.selections
Get-Content $env:TEMP\lf.selections

At least for the Windows terminal it takes 2 key sequences. The terminal goes to the default theme, then use the Alt-F to set it to yours.

also I've faced with the issue when some key bindings does not work after file opening (for example Alt-d) :(

The lf-pick script is not necessary: :insert-output lf -selection-path=/dev/stdout"

That particular setup breaks Helix mouse scrolling, after coming back from lf, due to some escape characters used in lf

To avoid that, we may run lf inside a tmux popup, It works only if Helix is already inside a tmux session, of course.

lfmux(){
  local TEMP=$(mktemp)
  tmux popup -h 100% -w 100% -E lf -selection-path=$TEMP
  cat $TEMP
}

lfmux

It does open multiple files, without breaking anything.

I was inspired by @webdev23 tmux, but wanted zellij and yazi, so here it is for those interested.

This does not mess up the helix terminal. Note yazi is not suitable from helix insert-output. Note zellij run forks and you don't get the selections from the current interaction, so that is why this is broke into two commands.

However, I don't find it an issue to perform two key sequences in helix to open the files. They are also cached, so you don't have to pick agian if you want the same files.

config.toml

A-z = [":run-shell-command zellij run -fc -- yazi --chooser-file /tmp/yazi-chooser-file"]
A-Z = [":new", ":insert-output cat /tmp/yazi-chooser-file", "split_selection_on_newline", "goto_file", "goto_last_modification", "goto_last_modified_file", ":buffer-close!"]

lf -selection-path=/dev/stdout

lf -print-selection works also. Additionally instead of theme switching :redraw solves UI re-rendering.

[keys.normal]
C-f = [":new", ":insert-output lf -selection-path=/dev/stdout", "split_selection_on_newline", "goto_file", "goto_last_modification", "goto_last_modified_file", ":buffer-close!", ":redraw"]

Thank you for this.
The best version of this I've found so far (from scratching around in all the various answers), is:

C-f = [":new", ":insert-output lf -print-selection", "split_selection_on_newline", "goto_file", "goto_last_modification", "goto_last_modified_file", ":buffer-close!", ":redraw"]

With no lf-pick script needed.

It almost works too! But you need to have modified a buffer to get it to open, and it doesn't open from the current location, which is a pain.

I think it's a testament to how much helix needs this functionality that we're all scrabbling around in here, trying desperately to make something work...
