Can anyone explain to me some ADVANTAGES and DISADVANTAGES of automatic code generation provided by applications such as Dreamweaver?
i have come up with the following:
Advantages
- implement an application quickley
- code that has been tested and debugged
- view the code to see what effect it has
Disadvantages
- Code can be difficult to understanding is limited
- Difficult to add to the generated code if developers understanding is limited
more advantages would be great
thanks
I don't agree with two of the advantages you list. My thoughts are:Quote:

- Provides little or no incentive to improve programming skills
- Code can be difficult to understanding
- Can be limited in scope and sophistication
- Code would still need to be throughly tested and debugged
- Can be difficult to debug WHEN something goes wrong or does not perform to specs
- Difficult to add to the generated code if developers understanding is limited
- Difficult to maintain and/or enhance without fundamentally rewriting it
cool constructive critisisms are just what i'm after
But wouldn't you learn from observing the code generated?
and surley applications such as dreamweaver would not allow code to be generated that contained bugs?
Bugs do not occur randomly through transcription errors and spelling mistakes, they most frequently occur by a difference of understanding between the implementor and the designer as to the function of the code. This is every bit as true for automatically generated code as it is for human-typed code ... arguably more so.Quote:

Does anyone here like autogenerated code, if so why? there seems to be a negative vibe here!
cheers
It depends on the degree of the code being generated. If it's skeletal, then yeah; I love it. For instance, in .Net, if you implement something in a class; it draws out everything you need to override and have (along with everything else intellisense provides). Same thing with visio. You design the entire project without a single line of syntax and it will create the outline framework for you. You still have to give the objects their functionality, but you don't need to keep refferring to your original design.
This kind of goes along with what Hack had said -
As long as the automated code generation is doing the mundane tasks, I'm for it. The key word is "mundane." If after the code is generated, you can say "I'm glad it did all of that for me so I didn't have to." You're ok. But if you say "I'm glad it did all of that for me because I had no clue." Stay away from them.
so future development of programming skills effected by auto generated code everyone hates
But it's cool for structuring the framework for the devloper to start coding
Does anyone agree that auto generated code will ensure the application adheres by the rules of the programming language and help create an application with minimal errors?
I'll meet you half way and say "sort of."
Good code is two things. It works, and it works the best way that it can with maximum efficiency and low overhead. Templates do their best to make it work, but it's a universal solution to your unique problem.
This may be more symantical than anything else, but, as long as nothing more than outlined framework is generated while the real coding must be done by the developers, then I can agree with it being autogenerated.Quote:

Auto generated code, just like anything else in programming is a tool. You use the right tool for the right job. I agree that using autogenerators for the mundane stuff is a god send. Take for instance a project I'm working on. Over the last few months, my cohort and I have been buisy building tables to hold the data we need. Now that we have that 90% done, I'm ready to generate the stored procs for those tables. How ever I wasn't looking forward to building the CRUD procs needed for the nearly 50-some odd tables we have. For those basic sprocs, I'm glad there's an autogenerator (I used mygeneration for this) to create them. I also used the tool to build my base classes to interact with those sprocs. Granted that's just the basics, for the more complex queries, I'll have to create the sprocs myself and integrate them into the classes, but that's the "fun" part.
Yes and no. The result is only as good as the template. One of two things will happen, you'll get something clean and pristine, or you will have very quickly automated errors right into the app. The result is also only as good as the inputs into the template. I ran into one issue when I was generating my base sprocs and classes. I have one table that will only ever have one row in it, so I didn't put a PKey on it. This caused the auto generator to choke. But that's OK, since I got the other 99% done, dealing with one table/class is a walk in the park.Quote:

The problem with auto code is that, as sevenhalo mentioned, it's a generic solution for everyone. It can never be specific to all needs. There will always need to be situation specific code that could never be automated. I've tried to do this with error handling before... but in every sub, the situations are for the most part so specific, that it can't be generalized enough for automation.

It is worth noting that most of us work with automatic code generation all the time - the windows forms designer(s) are code generators - if you look in the form class's InitializeComponent sub you can see it in all it's glory...
No argument...but I would classify that more along the lines of what sevenhalo termed an "outline framework"Quote:

Autogenerated code is clothes off the rack. Hand generated code is custom-made clothing. Unless your body is off the rack, off-the-rack clothes won't fit as well as custom-made clothing. They probably won't look as good or last as long either.
I prefer to generate all my own code - that way I understand all of it, not just most of it. (Now if only I could remember to make my documentation adequate enough so that I could still understand all of the code 5 years after I wrote it ...)
Framework type code generation is actually quite useful. For example I use an Object-Relational mapper that generates a lot of code for serialising objects to/from tables. Given that there are about 250 tables and each of them has between 5 and 50 fields I'm glad I don't have to write all that code myself.
Take MS FrontPage for example: Its terrible and known for generating much unnecessary code and bloat. Probably same can be said for dreamweaver but to a lesser extent. Now coding in Notepad is cleaner but tedious and time consuming. Like already posted, you use the right tool for the job as each job is different, especially when you have a time constraint like a budget. I hate autogenerated code in web development software for anything more then scripting a basis for a template page or something.
Autogenerated code does not really teach you how to c0d as only writting and debugging it manually will you gain the most knowledge and skill.
Depends what you term a "bug". Run a non-trivial page produced in Dreamweaver or FP through a validator and see how full of junk it is. Yes FP is worse but they are both bad. The many disadvantages far outweight the very slight productivity advantage through using either product.Quote:
