This is a visual colorized quick directory navigator for linux console. Quickly change current working directory with a pretty gui. Manage bookmarks for "quick jump". Written in nodejs and blessedjs module.
This is a POC "fullstack-everywhere" javascript programming. Nodejs + blessed js brings to you a powerful tool to make every complex console app you need without using perl/python/lua/tcltk and other stuff like this.
Type "ccd" to quick change directory
$ ccd

Clone or download codes. Go to root directory (where app.js is).
$ cd /your/path/to/root-dir/
Example:
~/software/qcd
+ app.js
+ package.json
+ exitcwd.sh
Execute npm install to install required modules:
$ npm install
Edit paths (first two llines) in "exitcwd.sh" if you need:
$ nano exitcwd.sh
#!/bin/bash
QCD_PWD_FILE="/tmp/qcd.todelete"
/usr/bin/node ~/software/qcd/app.js "$QCD_PWD_FILE"
if test -r "$QCD_PWD_FILE"; then
QCD_PWD="`cat "$QCD_PWD_FILE"`"
if test -n "$QCD_PWD" && test -d "$QCD_PWD"; then
cd "$QCD_PWD"
fi
unset QCD_PWD
fi
rm -f "$QCD_PWD_FILE"
unset QCD_PWD_FILE
Add an X attribute to execute script
$ chmod +x exitcwd.sh
Add an alias inside your ~/.bashrc or ~/.profile like:
alias ccd='. ~/software/qcd/exitcwd.sh'
Note: Open & close the terminal to active alias
You can't change console CWD because the nodejs process is executed as a child of bash process. You can't do this even if your code is written in cute C/C++. Bash need bash scripting. You need to "share" selected directory info that lives inside nodejs application back to console process in some way. One way is to put such info in a file and than execute a "cd" command.
Here are the steps you have to follow:
- Create a "CD" script if not exist
~/software/qcd/exitcwd.sh
exitcwd.sh
==========
#!/bin/bash
QCD_PWD_FILE="/tmp/qcd.todelete"
/usr/bin/node ~/software/qcd/app.js "$QCD_PWD_FILE"
if test -r "$QCD_PWD_FILE"; then
QCD_PWD="`cat "$QCD_PWD_FILE"`"
if test -n "$QCD_PWD" && test -d "$QCD_PWD"; then
cd "$QCD_PWD"
fi
unset QCD_PWD
fi
rm -f "$QCD_PWD_FILE"
unset QCD_PWD_FILE
Add an exec attribute to execute script
$ chmod +x exitcwd.sh
Once created you can't execute it because Shell scripts are run inside a subshell, and each subshell has its own concept of what the current directory is.
The only work around is to use an alias inside .bashrc or .profile :
alias ccd='. ~/software/qcd/exitcwd.sh'
