Xcode and Ruby function menu

Thanks for the tidbit. For Ruby, I currently use TextWrangler (free), but might be moving to TextMate (fee).
I use XCode a lot for C, C++ and Java. It has some quirks, but is basically a pretty good editor. I just recently figured out how to turn on code completion. That sure is nice.

Has anybody tried the Netbeans 6.1 IDE (there also is a Ruby-only IDE)? Till now I haven't had any breaks in syntax highlighting with that IDE (you know Scite? ^^).
One year ago I tried XCode, but it wasn't good for me. I also tried TextMate - seemed to have a good syntax highlighting (but is it really free? I don't think so.)

I use Scite occasionally too - on Windows, when I need line numbers. I said "fee" for TextMate, not "free".
Last year, I went to a Ruby conference and Sun demonstrated NetBeans 6.0. It looked good, but I have yet to download it. I really liked the interactive debugger built into it, but alas, that won't work for SU. I told Sun I would pay $1,000 for an interactive debugger that works in SU.

It's possible to hook into all methods like all Ruby debugger are doing. And we also need to change $STDOUT, $STDIN and $STDERR. So it would be possible to have an own console. But a debugger talking to NetBeans hm ... And all still works for XCode and TextMate?
Don't know, why Ruby programmers use "for" statements - they aren't "the Ruby way"
Ruby provides iterators and the "each" (each_index, each_with_index, reverse_each, to, upto, downto, times) method.azuby

Hmm. When I first came across Ruby I was enamored with these constructs. However, there is no such thing as a free lunch and the fact is that they are all slow. For my stuff, significantly slower than plain old simple for-loops - now you can argue they're semantically identical until your blue in the face.. Not as sexy, I know, but I'm old and wise and detest fancy language features that have hidden costs almost as much as I detest feats-of-engineering for engineering's sake. Been there, done that, got the t-shirt. Move on.

Hehe, blue? OK, maybe you really need half of a second. Time is money. But sex sells

Well perhaps I was just grumpy last night.
But that link shows what I know, which is a simple for-loop is around 10% faster for pretty much zero loss in readability. I'll take the 10% thanks.There is a real danger with Ruby of not understanding how much work you're asking for in using these cool constructs. Look at the Struct stuff - obscenely slow. Ditto expressions in which one is making Ruby do a lot of copying behind the scenes. It might look nice and compact on the outside, but... And some of the self-serving arguments you hear about "hardware is cheap" are a bit, well, self serving!

Hi,
I'm extremely unknowledgeable about scripting in general, and SU ruby in particular, but have a need (more a desire) to go through and Mac'ify any of my ruby set that give me Console(system) messages on start-up and in use,
It seems the main error (that I see) lies within SU itself and is there as soon as I load a clean instal of SU, before adding any additional rubies. It may or may not be a problem, but it generates pages of reports, which can't be good.

[0x0-0x45045].com.google.sketchupfree7[548] #<NoMethodError: undefined method `rendering_options' for nil:NilClass>from time to time I send these reports to Google (to no avail) and to individual authors who have then, tidied up the code.
I have also used Xcode to clean some scripts, and solve some glitches, so I know it all helps.
My first question is, On a script by script basis, can Xcode be set-up to 'find all>repair all' for these types of errors?

You'd have to write a prtty sophisticated regular expression to catch and change all these. You'd be running the risk of screwing up the scripts if you get anything wrong..

A simple search and replace of " (" with "(" should work.

A script is being required/loaded twice.

This is just an error in the script. My total guess would be a script that is reading the rendering_options when there is no active_model and thus getting nil as the result.

That's a mac thing? Or does SU load scripts before a model is ready?

AdamB,
cheers for the reply, before attempting to write any rubies myself I'm trying to analyze what I can and can't see using Xcode and Console (in combination)
it appears (to me) that if a ruby or it's loader.rb and subfolder reside in SU Plugin folder they will be initiated on start-up whether required or not and generate error reports if they have a prerequisite for "xxx" which is not available/selected prior to start-up(which, of course it's not)
This type of error does't seem to be generated for rubies that are placed inside their own sub-folder with a non-automatic step in their path i.e. rudy console, or a separate toolbar ruby that has it's own sub-folder that contains a on/off-button for an in-folder loader ruby that opens/closes the desired ruby.
Not even sure I follow that myself, but main lightup ruby (for example) appears to have to a degree of separation (for activation at least) and cannot generate errors and cause conflicts, unless it's actually being used and there's a problem.
What I think I'm after is a way to active/de-active any ruby, from within SU using a single(per ruby) external action.
Do you know if that's even realistic en-mass?
Which Xcode template is appropriate for SU rubies? or is there an importable or custom layout that's preferable?
cheers
john
