simple file manager

Description

sfm is a simple file manager for unix-like systems.

• pthreads(7) to read events, no timers.
• BSD kqueue(2) - kernel event notification mechanism.
• Linux inotify(7) - monitoring filesystem events.
• dual pane.
• bookmarks.
• open files by extension.
• bottom statusbar.
• vim-like key bindings.
• filter.
• no dependencies.
• c99 static linking.
• based on termbox.
• Inspired by vifm and noice.
• Follows the suckless philosophy.

Installation

current

git clone git://git.afify.dev/sfm
cd sfm/
make
make install

latest release

[ "$(uname)" = "Linux" ] && shacmd="sha256sum" grepf="--color=never"|| shacmd="sha256"

Run

Configuration

The configuration of sfm is done by creating a custom config.h and (re)compiling the source code. This keeps it fast, secure and simple.

sfm's Issues

Can't open sfm in DWM

1. I did try to open sfm in st using "st -e sfm" got an error - child terminated due to signal 11

2. from dwm I couldn't open the sfm and found error in dmesg

dwm config
static const char *sfmcmd[] = { "st","-e","sfm", NULL };

dmesg :

suggestion:

Custom colors

Would be really nice to see an option of setting custom colors, for example, in the config.h file.

Shell access from the file manager

Mostly coming from lf file manager, but I believe that quick access to shell could be really handy. Either in a form of a shell bar appearing on a key press, akin to how filter works now.

Or just have a key to open current folder in a shell. Like, you press key, get into terminal from the same folder you were in, do what you want, type exit and get back to the file manager.

Buffer overflow on symlinks

when any symlink loads it causes a buffer overflow and the program immediately terminates,

[Feature request] - Add file type specific icons

Maybe using the same system used to default apps, and using blank as fallback. Probably better to have it in a separate file than making config.h too large.

Hiding dotfiles

Is it possible to bind some key for hiding/unhiding dotfiles? They are usually distracting.

Renaming of files

I just compiled sfm and like it very much already. Thanks for providing this! I ran into one stumble block though...

I doesn't seem to be possible to use spaces or non-english characters when renaming files with the cw command. Is this a bug? Would it be possible to add this functionality?

Also, if the filename is very long (like 60 characters), you only get the remaining character space left on the line to use for renaming the file (like 10 characters). Perhaps to skip showing the original name on the editing line could be a good idea (since you see which file you have selected for editing in the file list above anyway). Or rather, one could have the original name there for editing (like if you have a long filename and just want to change one or two characters).

So what do you say?

Visual copy

Hi @afify ,

As requested, here is the new issue explaining the visual copy problem.

I am able to copy files and see them update, however, it only copies a subset of files on both systems. If I copy 5 it may paste 3; this happens on both systems (see below for a video of both). Also, in some cases I can get it to trigger a segfault on delete d, when I select too many files, there is a "Cannot allocate memory" on mac and a core dump on OpenBSD.

Video demonstrations

• macOS
• OpenBSD
• Segfault

In my case I run on dedicated hardware for OpenBSD, which I have two machines a laptop and a server. Both exhibit the same issue. And for additional context on OpenBSD I run xterm and an mac I am running their vanilla Terminal v2.8.3.

File types and default programs

Hello!

I have been playing around with sfm and it is very neat and lightweight! I was wondering on the choices on default applications. Would it be useful to not have apps choose between (or fall back to) xdg-open or some predefined apps? I am sure you have thought of this, but having a configuration file of some sort to set some defaults? Or define new filetypes that an be added to the images/arts/pdf/obj/etc... extensions. I was curious if this was in the works.

Otherwise awesome!

can use this as mi main file manager ?

like having all things thas actualy make a graphical windows manager like manage usb and devices and what app opens a file (MIME types)

how to open no extension file with vim

i want to use vim to open no extension file, but when i set an empty string it don't work

threads build on mac

Hi @afify,

So I figured the pull request was not a good place for this conversation. I went to build on mac with and I am seeing this,

Which is the same error I am getting on OpenBSD. It seems you have the structs defined in sfm.c but the variables defined in config.def.h. I am sure this is something you are seeing.

sfm terminated by signal SIGABRT

After upgrading to 0.3 I have such issue:

Again, there were no such issue with 0.2.
There is no such problem on macOS.

No correct selection line re-drawing in fullscreen

Hello! Here I have a visual issue: in fullscreen when you go to directory, selection line from previous directory and some very long file names are displaying. It's hard to explain, so, screens.

Here I'll go to "somedirectories"

And here what I have

Breakage

Does'nt open after installation. error show [FAILED 1773] tb_init()

control c killing just mpv and not sfm

Make it so sfm does not closes itself after pressing control c in mpv/sxiv.

My idea is making it so mpv stops running after i kill it with control c but sfm stays

Scrolling doesn't work properly

Steps to reproduce

1. There is a folder with a lot of files (e.g. 300)
2. Start sfm
3. Scroll from top to bottom (using Pg-Dn or j)
4. Scroll back to top (using Pg-Up or k)

Actual behaviour

There is no way to scroll to actual top.

Expected behaviour

It should be possible to scroll up to actual top.

Configuration

Aborted (core dumped)

I opened and edited some files with sfm and left it open for a while then eventually double free or corruption (!prev) and Aborted (core dumped) showed up and sfm crashed. I am using st and tmux.

Issue with opening sfm from a script/dmenu

An issue that I spotted is when I try to run sfm from a script, it fails to start.
I tried "st -e sfm", "st sfm" or just a script with sfm, but nothing succeded unfortunately.

**replace strncmp**

please add ability to run sh files from file manager

why do I need a file manager that can't run files?

2 panes

I found sfm wonderfull, but in my opinion (sense of taste, if you will), I feel rare having 2 panes, is there an option or a flag to only have 1 pane, or do I need to modify sfm.c in order to achieve that.

Thansk in advance!!!
