Fuzzy cd for project dirs

When working between projects, I realize that I almost always repeat the same few tasks including:

• Typing cd <path> to enter the project directory
• Typing git fetch or git pull to check/merge any changes upstream
• Typing <Ctrl>-b , while in tmux to rename the window to the project name

By incorporating the wonderful command-line fuzzy finder fzf I wrote a small bash function called cdp to automate these steps.

The function is written for two levels under a common directory (e.g. ~/dev) where the first level is the github organization name and the second level is the repository.

From the command line, typing cdp will bring up a fuzzy-finder window with all organzations and projects under your ~/dev directory. You type characters until finally selecting the project to cd into. You can also give cdp a string as an argument to limit the paths listed at the beginning.

If your project is a git repo it will then run git fetch as well as displaying verbose branch info compared to the upstream and the status of your working directory.

The latter half of the function only runs if you are in a tmux session. You can customize the rename_parent and rename_proj bash arrays or leave as empty (). For example in the code below usf-hii/hii will substitute the organization usf-hii with the shorter string hii which will reduce the characters for the tmux window name.

Example:

$ cdp snp

Brings up a fuzzy finder menu:

> ./usf-hii/snptk
> ./usf-hii/snp-util
2/18

Adding the character t and hitting enter takes us to the usf-hii/snptk project, fetches changes, shows us verbose branch info, short git status and sets the tmux window name to hii/snptk.

In this example we have 2 commits ready to be pushed and one file with changes not yet staged.

> snptk> git fetch --quiet (git@github.com:usf-hii/snptk.git)
* master 66cc97c [ahead 2] Fix snpid-from-coord output to delete file
 M tests/test_helper.py

countskm@jabba:~/dev/usf-hii/snptk (master * u+2)
$ # do your work now...

Here is the function if you would like to add it to your ~/.bashrc:
