sdn

sdn is a simple directory navigator that you can invoke while editing shell commands. It enables you to:

• take a quick peek at directory contents without running ls

• browse the filesystem without all the mess that Midnight Commander does: there’s no need to create a subshell in a new pty. The current command line can be simply forwarded if it is to be edited. What’s more, it will always be obvious whether the navigator is running.

Development has just started and the only supported platform is Linux. I wanted to try a different, simpler approach here.

Building

Build dependencies: CMake and/or make, a C++14 compiler, pkg-config
Runtime dependencies: ncursesw

$ git clone https://github.com/pjanouch/sdn.git
$ mkdir sdn/build
$ cd sdn/build
$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug
$ make

To install the application, you can do either the usual:

# make install

Or you can try telling CMake to make a package for you. For Debian it is:

$ cpack -G DEB
# dpkg -i sdn-*.deb

There is also a Makefile you can use to quickly build a binary to be copied into the PATH of any machine you want to have sdn on.

zsh

To start using this navigator, put the following in your .zshrc:

navigate () {
	# ... possibly zle-line-init
	eval `navigator`
	[ -z "$cd" ] || cd "$cd"
	[ -z "$insert" ] || LBUFFER="$LBUFFER$insert "
	zle reset-prompt
	# ... possibly zle-line-finish
}
zle -N navigate
bindkey '\eo' navigate

As far as I’m aware, bash cannot be used for this, as there is no command to reset the prompt from within a bind -x handler.
