Ruby Code Snippets

thomthom

Imagine a newbie who knows the ABC of Ruby programming. He's lost among 1000 code lines and doesn't grasp the essence of a plugin. Snippet (10 or so of lines) does.
Thnxs.

Yes - as long as one makes the assumption that they know the basics of the language.

Have you looked at the snippets linked in the previous link? Got a particular concept in mind? Particular beginner issues to address?

Chris Fullmer

There are lots of snippets lying around. I started a video tutorial series where I specify a simple task then write the code to accomplish, explaining line by line what the code is doing. The API also has many snippets of code in it (definietly could use more, slightly more robust snippets).

I like the idea of doing more to help beginners figure things out for sure. I still have not figured out the precise best way to do it though.

Tons of snippets are lying around, but few have 3D-SU goals/concept. What I would tell is that SU is specific for concepts relating to 3D expressions. Such concepts would first be enumerated: concept of rotating , concepts of translation, and so on. A master of SU-Ruby (I am keen to tell Gouru for their overwhelming production under rbs label --with some exceptions--) would express a concept with easyness parcimony, not at the hand of a novice. And then the motivated novice, I am sure will test the snippet, rearrange it and ONE day childbirth (!) snippets which will became a plugin NOT rbs one.
Cogitations or Hallucinations, it's up to you to judge.

I am ashamed to tell thanks for my ignorance.

Yes, I know the site of martinrinehart.

Thanks.

I stumbled upon this post:

Ruby Script Video Tutorial - Multiple PushPull Script
Postby Chris Fullmer on Thu Nov 05, 2009 4:53 am
Hi, this video shows how to write a script the does a push/pull over many selected faces. Its about 10 lines of code, and I explain it in under 5 minutes. I could even be simplified down to 1 line of code really. But that is pretty dense code. So writing it in 10 lines is easier to read

I would not have said it better.

Thanks Chris.

Here another post by Chris who illustrate my idea (His idea).

Ruby Script Video Tutorial - add Construction Points
Postby Chris Fullmer on Fri Oct 30, 2009 5:39 pm
Ok, this is my first attempt at a real time, script writing tutorial. I might do another here shortly. I know some people are not fond of my videos, so I've done this to spite them And I've heard some people like the videos a lot, so those people are allowed to watch and listen.
But I warn you, this is Ruby scripting in real time. So its not super duper exciting, unless you like Ruby or want to learn to script.
It's only about 6 lines of code, so you can't get too confusedI hope.
END

You're RIGHT Chris.

What else.

Sorry, but I'm really good at lurking..

Have you noticed my Ruby Newbie's Guide to Getting Started

which points at RUBY RESOURCES

Larsen

I am not talking about RUBY RESOURCES, but about perception process. By the way, do you know from whom we inherited lurking?

Origin:
1250–1300; ME lurken, freq. of lower2; cf. Norw lurka to sneak away

... probably from Scandinavian (cf. dial. Norw. lurka "to sneak away," dial. Swed. lurka "to be slow in one's work"), perhaps ult. related to M.E. luren "to frown, lurk"

So it probably came from Viking Norse, via Middle English, as a result of the Norse invasion into Britain (circa 875-950.)

Didn't read all of the above, how about this SketchUcation Topic? Been there lots of time to look at stuff. Thanks to Jim!!!

Very interesting link.

"snippet" does not mean 'small' ...

... it means some code that you can 'cut and paste' into your own code project.

If we're being pedantic then "snippet" is the diminutive of "snip" so it does in fact mean "a small portion of".

Dan Rathbun

Ok fine.. I'll give ya that.

But he wants a word that is smaller than small (limited to 10 lines.)

How about pygmy code or pygmy snippet ??

kwalkerman

How about compiling a list of simple plugins that newbies can learn from? I find it is really helpful to learn from something that actually does something useful. We can develop a list of existing plugins, that are well-written, short, and accomplish something useful. I've learned alot from reading other people's code, and it definitely would've been useful to me to have a short list of plugins to download and learn from.

I think that lots of people on this forum could develop a short list of their plugins that would help a beginner. This would provide an excellent resource without sapping TONS of time.

Thats not a bad idea. Many of my smaller scripts are simple. There are always questions about learning bad habits from others. I try hard, but I'm sure there are still things I do wrong. I'd hate for others to learn that from me.

Also, am I the only one that finds the linetool.rb rather dense to read? I have not looked at it for a little while now, but when I was learning, I could not make heads or tales of that thing.

Yes. I think a cleaner linetool would be useful.

kwalkerman

I also found the linetool.rb pretty dense.

It would be helpful to have some other coders review the files and make suggestions for cleanup prior to submission to the thread. I will definitely volunteer my material selection plugin (http://forums.sketchucation.com/viewtopic.php?t=31378), but would definitely like some criticism regarding the coding and clarity prior to having someone learn from it!
