Style and form in generated code

[honey the codewitch]

absolutely. typically the CodeDomProvider framework will even generate one for you =)

So it's you who torments the rest of the world with half baked, unorthodox rule engines. Has any one of these ever worked to begin with or sucessfully survived all attempts to derail it by clueless bosses with ever crazier new rules? The next step then would be a half baked rule engine with also half baked modifications to the (unorthodox and uncommented) generated code, which of course may never be generated again. Excellent. What a joy to see how the will to live is drained from those who have to maintain that thing, once Dr. Frankenfurter was done half baking his rule engine has left in search for new gullible victims. :-)

I have lived with several Zen masters - all of them were cats. His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.

In my defense I've only ever made a rule engine that generated code once, and it was used for years, and it worked. You maintained the damn thing by maintaining the rule specs, not the code. The code generation could alter all three tiers (SQL schema, middleware XSD and code, and front end admin UI stuff (non admin pages were not generated because that's stupid in practice, but it *did* expose functionality to the front-end that the front end could use in the form of rule aware javascript and html widgets) I generate mostly state machine code and things like parse tables. Those will always be incomprehensible and if you try to manually modify the state machine you deserve to be chased with a ball peen hammer.

I concur - do what you like in generated code - it's generated, not for reading or modifying! Just don't forget the big "Keep your stinking paws of this code you dirty ape!" notice at the top!

- I would love to change the world, but they won’t give me the source code.

As long as the generation tool is capable enough that I never have to hand edit its results I really don't care what all is inside the sausage factory. When the generation falls short and I need to hand-edit the results or worse write a fix tool, the nastier the generated output is the more I'll hate the guilty party. The flip side is when it is simultaneously simple enough in scope and capable enough in function to ingest my modifications without problem for round trip modifications (*cough*WinForm Designer*cough*) that I'll fall in love and still be mourning not having anything equivalent in newer projects (web, wpf, uwp, android, ios) years later.

Round tripping was cool even if it wasn't perfect. It was the (almost) perfect solution to providing VB6 style designer functionality without making it opaque like VB6 did.

I'm certainly not. =D

I'm too do a lot of generated code (mostly JS as today)... The only comment I add is a warning about the changes one thinks to make - futile (especially when I minimize the generated code :-))... I try to generate optimized code, so I will use variables for constants I reuse in the code, others will be in-place...

I try to generate somewhat "portable", optimized code in that order. By portable in .NET i mean code dom constructs that work for most if not all languages. Sometimes that means trading against optimization but it's usually worthwhile if you're making a tool for general purpose use like a parser generator, as long as the hit isn't that big, or somewhere time critical.

I've just developed a little class to greatly abbreviate building CodeDOM trees. I'll probably publish a Tip & Trick on it once I've used it for what I'm using it for. I like to dogfood things before I post them if possible.

I have an app that generates models and (optionally) viewmodels from stored procs in the seleted database. In both entity types, I give the user the opportunity to specify namespaces, and base classes (that the generator does not create). All generated model and viewmodel entities are generated as public partial, and all properties are virtual, with a comment that reminds the coder that the model/viewmodel in question is generated, and that any changes to the generated file(s) will be lost if they regenerate the entity, and further, and changes should be made to either a partial extension file, or inside an deriving class. For the record, my app does it better than the ado.net project template, and is SIGNIFICANTLY less buggy or finicky. Beyond that, once you click the generate button, it creates all of the entities in less than 5 seconds in a database with over 200 stored procs.

Nice. I used to write tools like that back when i was doing this professionally. Part of me misses it. Part of me is glad i don't have to deal with that crap anymore. :laugh:

Just make sure to add some attributes so designers know not to check the code for style issues. I think the GeneratedCodeAttribute does that in .NET. Nothing is worse than having some blue information and yellow warning icons for stuff you can't change X|

Fair enough. I always mean to but sometimes I forget. Lately I've been pretty hardcore about warnings and documentation but I forget those silly messages.

[honey the codewitch]

The thing is, I don't know that I can easily add that feature. All this really is is some code to help you write code generators. It's not a code generator. It's an attempt to make the codedom not kill your fingers, and actually make it vaguely readable.

If you generate code that I can't touch, but that will sit around in my project you owe it to all that's good and holy to add that attribute. God kills a puppy every time you generate production code without that attribute :(
