How to build GNU Octave with Qt5 on the Mac

1503512The graphical user interface of Octave 4.0 can only be compiled with Qt4. Homebrew is dropping 4.x support and moving towards 5.x. Several Octave dependencies have already been updated (e.g. Qscintilla2, see e.g. this issue. However, the upcoming Octave 4.2 (release is scheduled for September 2016) will have full Qt5 as discussed here.

The standard installation uses the command line interface. If you need Octave with graphical user interface then this should work
brew update 
brew upgrade #to get the latest qscintilla
brew install octave --with-gui --HEAD
Update: The post has been edited on Aug 20 since the new formula is now available in homebrew’s science repository.

Alfred2 Workflows (Update 2)

I have written some workflows for Alfred which should make the life of people working with an Apple Mac in science (mathematics, physics, engineering, …) more comfortable, see the Code section. For those who do not know Alfred: it is an “productivity application” or a very feature rich application launcher if you like. Alfred is based on spotlight but significantly increases its flexibility.

Update: All workflow include alleyoop updates.

You probably need to buy the Powerpack to use the workflows.
