LF: File browsing, Image Previews written in Golang

The last of the terminal-interface programs I haven't done a video on: LF the file browser. I have a lot of shortcuts in mine, but also image previews with ueberzug and special icons, and tips as well.
All of my lf configuration files (and those for everything else) are on my dotfiles git repository:
github.com/luk...
lf source code: github.com/gok...
It should probably be in your Linux distro's package repository.

It's great that Luke creates classic-style Linux video again.

[@jtrickett1974]

Excellent video as always. But you might need to update your dotfiles repo with your latest lf configs. Certain things aren't working as they do in your video i.e. video thumbnails.

[@kronikpillow]

you should read my comment above .. .about missing LARB Dependancies, it's working all right, you just don't have the packages needed for it to work installed, as they are for some retarded reason not installed by default

[@jtrickett1974]

@@kronikpillowMany thanks for your reply.

[@mik13ST]

I used to use Ranger for a few months, contributed some fixes, encountered many hiccups and in the end I jumped to LF as well. Another thing about LF is the lack of fancy features (compared to Ranger) makes it easier to maintain. This ideology is inspired by the Golang itself.

[@f23anone82]

Finally, the Linux related video from Luke

[@kronikpillow]

Luke ... most of the voidrice repo dependancies, like bat, ffmpegthumbnailer, and other programs used for many of your scripts in .local/bin/ are actually not installed by default, so a user can install your dotfiles, but 90% of the things won't work, until a user actually reads trough all the dotfiles, and identifies what he actually needs to install additionally on top of LARBS to get things to work ... so far identified missing dependancies, there are more actually related to .local/bin, althou still not identified fully what's needed for a full working voidrice dotfiles bat - for LF previews ueberzug - for LF previews python-pdftotext - for LF previews odt2txt - for LF previews calcurse - dependancy of the sb-clock status bar script transmission-cli - dependancy for dwm tremc - dependancy for dwm vorbis-tools - dependancy for the tag script in .local/bin opustags - dependancy for the tag script in .local/bin python-eyed3 - dependancy for the tag script in .local/bin ttf-joypixels - missing font from fontconf in voidrice ttf-liberation - missing font from fontconf in voidrice noto-fonts - missing font from fontconf in voidrice ttf-dejavu - this one is needed to fix the emoji showing whitespace glitch

[@TheSulross]

I went through my golang phase - even wrote some programs in golang that are running in commericial production apps, but anytime on the Intertubes one will soon see that Rust has eclipsed golang in all the conversations and attention getting. Well, system programmin where control all the memory allocation has its place, but golang garbage collected memory management and its primary concurrency model are rather great fit for all this cloud infrastructure software - which is a kind of middle-ware. After all, we're still coming out of a 20 plus years of writing Java middle-ware. But C was amy first programming language love so I'm more interested in Zig than I am in Rust these days. I really want to go back to writing code that has the smallest executables possible without resorting to assembly language while incorporating a lot of the lessons learned from the last 30 years about language design ideas. Zig still has some maturation to go through but am seeing the potential for it to fullfill this particular language vnirvana vision

[@astroid-ws4py]

You should also check about Nim, It is bassicaly a C with garbage collection and can be used as an alternative to Go

I'm here using it and it's Great😊

[@luxucn]

Lf has a "delete" command now, but not bound to any keys. So, you can just put "map D delete" in lfrc.

[@laz0rbra1n]

d is move. key bindings must be as arbitrary as possible so I suggest using i for delete.

[@luxucn]

@@laz0rbra1n I think the dev was mimicking vim's 'd' then 'p' to cut and paste, but TBH I was just as confused.

[@sodiumsalt]

[@kevind.shabahang]

Hey Luke, I love your videos. If you know of FOSS approaches to project/time management and TODO list tracking, it would be greatly appreciated if you can make a video about it. Extra points if you know of some terminal-based tools. I was trying gcalcli, but it's no longer syncing with Google Calendar. Perhaps that's a blessing in disguise...

Hi Brodie! Shapeshifting is a clever way to flex lf again. But your beard looks better on the original.

[@user-cf2pl9uy5k]

Hi Luke, appreciate your tutorials. You could also show on lf's wiki the info about how to add previews. I've been watching you for years, but I don't think newer people trust us to add our configs to their system, if you know what I mean...

R.I.P. ueberzug. I have instability using lf with ueberzug. After 1st preview it is stuck in loading state. I am not able to figure out. If anyone has solution please reply.

[@kj-marslander]

I'm trying to figure it out at the moment, I was using ranger and kitty for a few months, so I didn't notice when ueberzug died

[@WildVoltorb]

I've been using vifm, pretty happy with it. Also uses uberzug for previews, but unfortunately there's no uberzug support for wayland

[@CarlosRodriguez-nj6jp]

Thanks! btw the scope file hasnt been updated, it does not display video or pdf thumbnails yet

[@Y1001]

this is fantastic, thank you for the share

[@liamray2010]

Thank you. Question - why don't you use a whiptail for confirmation/input dialog boxes?

[@vdsw9166]

I was wondering if it has a thumbnail mode for media folder browsing; looking for files based on visual input is pretty important when the size of your meme folder gets out of hand.

[@godisgood5089]

I made the ~/.local/bin directory, put the script in there, made an alias in .bashrc and still have no idea how it's supposed to launch. bash: lfub: command not found.

[@mik13ST]

Yes, ranger is slow. I tried browsing a big Git repo in it on a RaspberryPi 1 and it wasn't a pleasant experience. One of the problems is Ranger being synchronous so when you jjjjjj down over a big directory, it halts until it loads the content. LF on the other hand prints "loading..." and you are free to continue jjjjjjj down uninterrupted.

[@otten5666]

I have tried to adapt to command line file management with Ranger and NNN but I just cannot get productive with it. I went back to Thunar to be productive again. Fight me.

[@ari-athbadminton0301]

Lf is pretty dope, but I've found myself using fff more. For switching directories, bulk rename, copy-pasting, etc. is much better out of the box.

Any way to do the lfcd() thing with ranger? That's all I've ever wanted from a terminal file manager

[@mik13ST]

I think the Midnight Commander should be the terminal file manager of choice for people like Luke. All these MC replacements with fancy features (image previews, icons, VCS integration) kind seem soydev-ish. Keep the traditions!

[@DorperSystems]

@I ain't no millionaires son! come on man get with the program. useful features = soyface. pointless minimalism = gigachad.

[@mik13ST]

​@@DorperSystems Gigachad, lol. In that case, Luke should switch to TTY console (what do you need X11 for?) and refrain from using terminal UIs (terminal wasn't meant to be used like this btw) by using plain ed to edit files. Maybe he could get an actual VT100 physical terminal. That would be gigachad.
