I am a religious follower of DRY (Don't repeat yourself).
In my line of work, I tend to use modelling tools (eg. UML) in order to plan out and structure my code. Once the modelling has been done, I create, test and implement the program (with comments). Once the program is in place for its intended purpose, I document the code to the end-user.
My question is about automatic generation of code and/or documentation. It seems to me that whichever task in my workflow I choose, it is a 1 way mapping.
ie. Model -> Code
Code -> Model
Code -> Documentation
Documentation -> Code
So if I change my code, I then have to update my model as well as my end-user documentation.
There are ways I can automate model generation, but I am generally at the whims of the modelling environment when it comes to model regeneration from code. As well as this, generating code from the model and generating the model from the code seem to be two different, complex problems all on their own.
I can generate code from my model, but sometimes it is not feasible to regenerate code from a model due to code modifications that occur when the code is actually deployed.
How do you guys handle these activities?
