What?

This program can split apart, and recombine, MATLAB scripts written using the Cell Mode feature.

Why?

Cell Mode is highly convenient for interactive development. A large task can be split into separate chunks which are repeatedly run independently, inspecting local variables and making iterative changes. I often use Cell Mode to document the steps of a machine learning pipeline. But Cell Mode can't be used when operating MATLAB from the comand line (such as on a remote server). You can only run the whole script as a unit. But after processing with cellsplit, each cell is a whole script so the flexibility is regained.

How?

cellsplit contains a very rudimentary parser of MATLAB syntax, and it breaks out every cell into a new script. It also breaks out bodies of conditionals and loops, since cells can be placed inside those.

Status

Unsupported features of MATLAB:

- `switch`
- (please file a bug if there is one I've overlooked)
