Hipster - theory exploration in Isabelle/HOL
Hipster is always under development, but feel free to play around with it! To install Hipster, you first need Isabelle and TIP-tools.
git clone https://github.com/tip-org/tools.git cd tools stack setup stack install
You can now clone the Hipster repository itself:
git clone https://github.com/moajohansson/IsaHipster.git
Finally, you need to tell Isabelle where to find Hipster and TIP-tools, which you just installed.
Do this by setting the environment variables
$HASKELL_HOME in the file
(create this file if it does not exist yet), where Isabelle normally has set
$HIPSTER_HOME should then
point to the path for the IsaHipster directory you just cloned.
should point to where Stack installs your Haskell executables (usually something like
See the Isabelle System's Manual for more info on how to set up Isabelle's system enviroment.
Alternatively, you may set the environment variables in your bash environment file, but then Isabelle will only find Hipster if you start it from the terminal, so I would recommend the former approach.
If you want to use Hipster from an Isabelle theory file, it needs to import the
IsaHipster.thy file (which essentially sets up Hipster) by including the
Now, you should be able to try Hipster.
Start up Isabelle on for example
Examples/TreeDemo.thy and have a go.
