Installation

I'm not aware of any distros packaging nimmm apart from NixOS, so you will probably have to compile nimmm from source on non-NixOS distros.

From source

You will need the Nim development toolchain. Furthermore, termbox-devel or libtermbox-dev is required for the terminal user interface.

git clone https://github.com/joachimschmidt557/nimmm
cd nimmm
nimble build

Nix

nimmm is included in nixpkgs.

nix-env -i nimmm
# or, if you prefer nix flakes
nix profile install nixpkgs#nimmm

Usage

Configuration

Some functionality of nimmm is controlled via environment variables similar to other programs:

Environment variable	Setting
EDITOR	file editor
PAGER	file viewer
NIMMM_OPEN	file opener
NIMMM_256	enable 256 color mode

Other configuration such as keybindings are configured in $XDG_CONFIG_HOME/nimmm.conf where $XDG_CONFIG_HOME defaults to ~/.config if not set.

Default keymap

The default keymap is similar to that of less.

Key	Default binding	Description
q	quit	quit
!	shell	spawn shell in current directory
j	down	next entry
k	up	previous entry
h	left	go to the parent directory
l	right	navigate to directory / open file
g	first	first entry
G	last	last entry
~	home	go to home directory
.	toggle-hidden	toggle display of hidden entries
/	search	start searching
Esc	end-search	stop searching
e	edit	edit file in $EDITOR
p	pager	view file in $PAGER
r	rename	rename file/directory
Space	select	select / deselect current entry
a	select-all	select all entries in current directory
s	select-none	clear selection
X	delete	delete selected entries
P	copy	copy selected entries
V	move	move selected entries
f	new-file	create (touch) a new file
d	new-dir	create a new directory
t	new-tab	new tab
w	close-tab	close tab
Tab	next-tab	next tab
1..0	tab-x	go to tab 1..10

Keybindings are customized in the configuration file. For example, if you prefer more Emacs-oriented movement keybindings, you can do this:

[Keybindings]

h=none
j=none
k=none
l=none

n=down
p=up
f=right
b=left

External programs

Dependency	Use
cp, mv, rm, mkdir, touch	nimmm delegates all operations on files and directories to these utilities to save all the error-handling and permission-checking work. These utilities should (hopefully) be on your UNIX system
$SHELL or fallback sh	an interactive shell
$EDITOR or fallback vi	an editor
$PAGER or fallback less	a pager
$NIMMM_OPEN or fallback xdg-open	a file opener
