Bash: Change directory to project: cdp
Cdp eases changing directory to a project. You define an environment variable `CDP_DIRS' for cdp to search and it will jump to the first found project. The project name is tab completed. If the destionation directory contains a file `.projrc' it will be executed. Example:
$ cdp ru # Press TAB + ENTER /mnt/proj/ruby$ # Working directory is now /mnt/proj/ruby
Usage: cdp [options] [dir] Change the current directory to (project) DIR. The array variable CDP_DIRS contains a list of directories to be searched. If the directory is not found, cd to the first valid directory of CDP_DIRS. If DIR contains a file .projrc, it is executed unless --noprojrc is specified. OPTIONS -h, --help display this help and exit --prefix=PREFIX use PREFIX for environment variables. Default is CDP_ -p, --projrcfile=FILE execute commands from FILE instead of standard initialization file .projrc -P, --noprojrc do not execute project initialization file .projrc -t, --title=TITLE specify terminal title. Default is first dir of DIR. -T, --notitle do not set terminal title -v, --version show version ENVIRONMENT CDP_DIRS An array variable whose members are the directories to be searched when the cdp command is executed. Example definition: CDP_DIRS=($HOME/proj "$HOME/Program Files") CDP_OPTIONS Default options to be placed in front of any explicit options.
1. Copy the file cdp.sh to a $PATH directory
2. Within ~/.bashrc, create an alias cdp to source cdp.sh in the current shell:
alias cdp='. cdp.sh'
3. Copy the file cdp-completion.inc.sh to /etc/bash_completion.d. If this directory doesn't exist, consider installing http://freshmeat.net/projects/bashcompletion
4. Within ~/.bashrc, set an environment variable CDP_DIRS. CDP_DIRS is an array variable containing directories to be searched by cdp. Example declaration:
CDP_DIRS=($HOME/proj "$HOME/Program Files")
Suppose you want to have an additional command cdq. With these settings in ~/.bashrc:
alias cdq='. cdp.sh --prefix=CDQ' complete -o filenames -o nospace -F _cdp cdq
the command cdq will use environment variable CDQ_DIRS instead of CDP_DIRS.
Sourced command or executed script
Why is cdp a sourced command and not an executable script?
- An executed script can't change the current directory. All it can do is change the current directory of the subshell in which the script is being executed
- Variable `CDP_DIRS' now is an array variable. Array variables can't be exported so can't be accessed by a subshell.
The download contains an additional test suite. The test suite requires dejagnu, tcl and expect to be installed.
To run the tests:
$ cd test; ./runAll
You can also include the project directory in the CDPATH environment variable. This way, the project directory will also be searched for by the `cd' command. From `help cd':
- "... The variable CDPATH defines the search path for the directory containing DIR. Alternative directory names in CDPATH are separated by a colon (:). A null directory name is the same as the current directory, i.e. `.'. If DIR begins with a slash (/), then CDPATH is not used...
