I'm looking for an online utility that will prettify and add explanatory comments to a regular expression. Does one exist?
I like the online tool: http://regexr.com
When you hover over the regular expression you will get an explanation of that part.
For what it's worth, I also like:
regex101.com, which is quite powerful, but technical. It features timing and steps taken results as well as permalinks for sharing a regex with explanation and test data.
regexper.com, which draws railroad diagrams of regexes. The results are very nice to look at and easy to understand, but there are no textual explanations.
Both are free to use.
There's a bunch of them listed in Steven Levithan's blog.
regexpal is the one I always use. I prefer it to the Flash-based RegExr.
I currently use http://rick.measham.id.au/paste/explain.pl from Rick Measham. It is a regex explanation tool that simply works.

I searched for a question about regexp testing/learning tools, but people usually suggest Windows based solution. I found one for ubuntu: redit.
However, I'm wondering if there are better tools for the job. So, without further ado
Q: What is the best tool for testing/leadning regular expressions
for linux/ubuntu?
Sorry if this is a superuser kind of question.
Thx
I rather like Kodos, which is a cross-platform GUI regex tester.
But there are many others. Have a look at the answers to How do you debug a regex? , there are many cross-platform solutions listed.
Why don't use web-base tools: http://regexpal.com/ and more here
My favorite http://gskinner.com/RegExr/ Adobe Air app. Worth a try
For simple regex I use the replace function in Sublime Text 2.
Best "tool" for learning regex?

Does anybody know any tool for validating the syntax of an Regular Expression? I dont want to validate if it matches or not with some text but I want to see if there are syntax errors in the regex (missing parenthisis etc).
Also, what about syntax highlighting? It would be a great help when writing complex regex.
I used RegexBuddy for more than half a year. Highly recommended.
http://regexpal.com/ has a form of syntax highlighting. As for validating, that would depend on which engine you are working with, since different engines support different syntaxes. It would be impossible to validate something without knowing exactly which syntax the engine you are targeting supports.
I like rubular.com

I have looked at the following software tools:
Ragel
ANTLR
BNF Converter
Boost::Spirit
Coco/R
YACC
ANTLR seems the most straight-forward, however its documentation is lacking.
Ragel looks possible, too, but I do not see an easy way to convert BNF into its syntax.
What other tools are available that can take BNF input and generate a corresponding, Unicode-friendly, cross-platform, standalone, C++ parser?
Many thanks for all suggestions.
Edit: Changed Objective-C requirement to C++.
Try boost.spirit 2.
The boost spirit user list is very active and answers are quick from the authors.
TDParseKit! (Most specifically, this page on Objective-C parser generation with BNF grammars)
Have you looked at QLALR? It is a creative Friday project from QtDF. I have not tried it personally, but the trolls seems to be pragmatic about their approach to problems, so I guess this is too.
You can try GOLD Parser! It's a great tool for parsing and generating. With a simple UI, all what you need to do is to provide a valid grammar file and select your favored programming languages for your output code.

Is there a regular expression tutorial that doesn't use a designer?
I learned the basics of RegEx with this tutorial
It talks about what happens behind the scenes and doesn't depend on a certain platform.
This is a great and quick getting started guide:
The absolute bare minimum every programmer should know about regular expressions
Check out Expresso I have used it in the past to build my RegEx. It is good to help learning too. Not really a tutorial but you can test out regex's with it.
RegEx Buddy, while also not a tutorial in itself, has been one of the best tools for me. The on the fly highlighting helps.
RegexBuddy is also nice, if I may add. There is a variety of similr tools available. A simple google search "regex tool" reveals most of them.
As far as for the tutorial, I can recommend the book "Mastering Regular Expressions" (I read the first, there is probably a newer edition by now)

I'm looking to work with others to quickly build a rather large class flow diagram that may or may not be strict UML. Can anyone recommend a networked, concurrent collaboration tool for such a task? Price is not an issue, but the target system must be Windows.
Surely someone must have done something like this in the past.
Any ideas?
DabbleBoard has an online diagramming tool that may do what you want. It should work on Windows, although it is a web-based and fairly low-level.
I don't know exactly how concurrent you need it, but Google Docs have just introduced a 'drawing' document type, which is basically a stencil based system like visio. It includes flowchart elements, and of course can be shared.
