sdn
===
:compact-option:
'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:
....
sdn-navigate () {
# ... possibly zle-line-init
eval `sdn`
[ -z "$cd" ] || cd "$cd"
[ -z "$insert" ] || LBUFFER="$LBUFFER$insert "
zle reset-prompt
# ... possibly zle-line-finish
}
zle -N sdn-navigate
bindkey '\eo' sdn-navigate
....
bash
----
Here we can't reset the prompt from within a `bind -x` handler but there is
an acceptable workaround:
....
sdn-navigate () {
SDN_L=$READLINE_LINE SDN_P=$READLINE_POINT
READLINE_LINE=
eval `sdn`
[[ -z "$cd" ]] || cd "$cd"
[[ -z "$insert" ]] || {
SDN_L="${SDN_L:0:$SDN_P}$insert ${SDN_L:$SDN_P}"
((SDN_P=SDN_P+${#insert}+1))
}
}
sdn-restore () {
READLINE_LINE=$SDN_L READLINE_POINT=$SDN_P
unset SDN_L SDN_P
}
bind -x '"\200": sdn-navigate'
bind -x '"\201": sdn-restore'
bind '"\eo":"\200\C-m\201"'
....
Colors
------
Here is an example of a '~/.config/sdn/look' file; the format is similar to
that of git, only named colors aren't supported:
....
cursor 231 202
bar 16 255 ul
cwd bold
input
....
Similar software
----------------
* https://elvish.io/ is an entire shell with an integrated ranger-like file
manager on Ctrl-N (I find this confusing and resource-demanding, preferring
to keep closer to "orthodox file managers")
