Python coroutine based state machine

I needed a simple state machine in a project I'm working on. Doing some research I came across coroutines. This post won't even try to explain what coroutines are. Instead, it just shows a super simple example of a finite state machine using coroutine.

Installing KPCLI on OS X

keepasscli (kpcli) setup

Notes on installing and configuring keepasscli (a.k.a. kpcli) on OS X 10.9 (Mavericks) and 10.10 (Yosemite)

date: May 2014

First, download kpcli.
Once downloaded, put it in its final location (e.g. ~/):

mv ~/Downloads/kpcli-2.5.pl ~/)

Make it executable:

chmod u+x kpcli-2.5.pl

Install perl dependencies via cpan

sudo cpan Crypt::Rijndael
sudo cpan Sort::Naturally
sudo cpan Term::ShellUI
sudo cpan File::KeePass

In theory that should be it, but there’s a problem with Term::readline. To fix it follow the instructions here

UPDATE

For the Term::ReadLine::Gnu the previous link didn’t work for me when updating to OS X 10.10. Instead I followed these instructions

Other dependencies

To be able to copy to the clipboard inside kpcli (e.g. xu or xp), you will also need to install these

sudo cpan Clipboard
sudo cpan Capture::Tiny

Finally, you can make an alias to kpcli including the DB location for fast access. Add the following line to ~/.bash_profile

alias kp="/Users/myuser/kpcli-2.5.pl -kdb='/Users/myuser/mydb.kdbx'"

Santiago, Chile

Great summary of Santiago: beautiful mountains, a BIG air pollution problem, lots of buildings ... and, of course, we are football fans.
