HTML/ Javascript/ CSS Pretty Printer
Posted on: 2007-04-26 20:26:38
I've been learning a lot of web programming lately. One way to learn is to look at other people's code. Unfortunately, to save space a lot of the web pages out there have all the white space removed. So I wrote this java program to format any web page so that you can study it.
  • It handles HTML, embedded javascript and CSS
  • It uses syntax highlighting for keywords and punctuation.
  • It adds links to Javascript function calls so you can click on them to jump to their definition.

Enter Url (Beginning with http://)

The program needs a lot of work. There are numerous errors in the output, like missing quotes, but it is okay for understanding the page. Just don't take the output and try to use it as HTML because stuff will be missing.

Unfortunately I designed it badly and I hate the source code. I don't even understand it anymore, and certainly I don't recommend anybody look at it. However, due to popular demand I am releasing it: webpp.zip. The best thing to do is start from the Main.java method and follow the functions from there.

I used your pretty printer and then read the following:

"Just don't take the output and try to use it as HTML because stuff will be missing."

It's a shame - an online tool like this would be really useful. You probably are aware of the bugs, but javascript inside html comments goes wrong, and some closing tabs appear to be missing too (the </html> went missing on my page; maybe others)

Please work on this tool - I think it could be great!

Update:

This was only a one-day project, and I don't intend to release the source code because it is too messy. I committed the cardinal sin of sitting down and writing code without any prior planning, and it is a mess. It's difficult to change and impossible to add any new features. The thing needs to be re-written from scratch.

Perfect reason to release the source, let someone else do it rather than having to start from scratch

I just realized that one of the reasons the code is so bad is because is that I am a C++ programmer. I failed to adapt it to Java, I just translated it line by line. In fact, TagParser.java is a C++ object I wrote years ago.
