Another developer here suggested this to me (Thanks Rich!) – but every time I use it I think it’s really useful, so I thought I’d share it.
When you’re working with a python package like “product.section.part”, you end up with a directory tree like so:
product.section.part
+ product
+ section
+ part
- module.py
Now, navigating through these directories is a pain – each time you want to edit module.py, you find yourself typing something like:
cd p[tab]p[tab]/s[tab]p[tab] [editor] m[tab]
# (the "/" is required to get past the .egg-info file) # i.e. this expands to
$ cd product.section.part/section/part/ $ [editor] module.py
Rich simply added a simple function to my .bashrc to do this automatically – so I now type
zcd p[tab] editor m[tab] #i.e. this expands to $ zcd product.section.part/ $ [editor] module.py
- It’s much simpler, and makes moving between packages that little bit nicer !
Here’s the script to add to your ~/.bashrc:
function zcd() {
X=`echo $1 | sed -e "s/\\./\\//g"`
cd $1/$X
}
Here is a slightly more advanced version that can deal with a src/ subfolder as well and falls back on the normal cd if neither directory can be found
function zcd() {
target=$(echo $1 | sed -e “s/\\./\\//g”)
if [ -d "$1/${target}" ] ; then
cd $1/$target
elif [ -d "$1/src/${target}" ] ; then
cd $1/src/$target
else
cd $1
fi
}

Autojump takes zcd, spanks it, and leaves it in a ditch:

Highly recommended!
