ARRAY Search [RUBY] ??

[RJHollins]

Keys to solving this, I think, are...

- Get all the information into a single data structure
- Test strings using regular expressions - they take some learning, but are super versatile.

Something like this...

Trog ... Thank-you ! I know you've been trying to take a little time off [at least from here] But I always look forward to your posts. Once again, the code and the internal descriptors have provided much to study.

What's interesting is looking at the code techniques you've used. I have been reading various Ruby forums [tutorials] and see all these things presented in your code. I'm a long way from understanding most of this.

I've been testing out the code you posted. I've gone in and substituted some of my intended integration via Inputs, and mod'd a bit on the variable names. This help me see some of the logic and syntax for what I'm needing to do.

I did find something confusing on the output. For my test, the outputs are showing as:

[["1", "test1"], ["2", "test2"], ["3", "test3"], ["4", "test4"]]

I'm trying to figure how to 'remove' all the brackets, quotes, & commas to just output a 'clean' Array list.

The destination for all the 'found' arrays are going to be fed into a 'pull-down' menu Selector. The idea is to parse an XML file into the 2 input arrays [patchnames, patchnumber]. From the search routine I can then more quickly organize these patches into a related sub-group. These groups will be fed to the pull-down menu, allowing the User to select a patch from the group.

The patchnames or mostly for display purposes. The patchnumbers are the actual MIDI PRGCHG values that I'll be using to control external VST plugs with.

This is all in effort to ease the User Configuration. Instead of the user manually entering in all the patch data.

It a concept I'm wanting to try to see if this would be better.

or something like this. it will search for string and return array with index and element from input array

Code: Select all

a = ["preset_test1","test2","preset_test3","test4"]
names = a.select {|x| x =~ /preset/ }
number = a.each_with_index.select { |i, idx| i =~ /preset/}
number.map! { |i| i[1] }
number.zip(names)


Hi TrojakEW,

Thank-you for posting code suggestion, unfortunately, I've not solved how to alter your code example to work with external inputs I attribute this to my rookie skills with Ruby [and I use the term 'skills' in the generic sense] I'm still playing with it, though ... it seemed a more specific [and hoped] easier code for me to understand.

I was able to modify TROG's code to take the inputs I was sending. The only issue was getting the outputs in a clean 'array list' format.

I think I should post a simple schematic to illustrate what I'm trying to accomplish, so as NOT to waste everyone time or add confusion. My bad

The output from TROG's post shows this:

[["2", "test2"]]

I don't understand how to have the output with no brackets ... just the 2 and the test2 ... but as separate outputs

Here's a schematic sample that I'm working from:

With TROG's search routine as the centerpiece, I've only modified to take 3 Inputs. The 'working' Output shows
the result ... but in a format that I don't know how to use.

The 2 text boxes below that show the format I'm trying to get to.

Hope this makes sense ... or maybe I'm thinking about this all wrong

Here is my modified version with 2 inputs. 3 outputs element names,element index a combined array name+index. Oh and my skills with ruby are almost same as yours . I'm ruby noob.

Closer

The 'found' INDEX [output] should only be those found, and in sync to the patchnames.

Thanks for looking at this Tronic !!!!!!

Hi TrojakEW,

Your latest 'modified version' .... WORKS !!!

Looking over the code, I see familiar terms and syntax that I was trying to use in my attempt. I did, however, see new terms, like the 'map!' tp get the index array. That's one I'd not seen before.

As to Ruby skills ... well YOU might consider yourself a 'ruby noob' ... but the code AND the internal comments you wrote are MUCH APPRECIATED I can actually follow along with your code ... still, I need to understand the internal workings, among many other things. This is great ! Thank-you.

Well, at least now I can start putting together the original idea, and see if this all comes together.

Thanks again for everyone's help in dragging along a rookie to a working destination.

Again with the Ruby Arrays !

So close ... yet so far ...

Finally getting back to a project idea, and this array search routine.

I have 2 arrays that need to be directly linked to each other. One is 'name', the other are 'patch#'.

I'm using a 'search' to separate items from the list into an output array together with it's specific patch#.

I'd like to separate this 2-d array back into separate string arrays to 2 outputs.

The output format is another puzzle ... I need to change the current format so it can be used in part for GUI display and part for MIDI data.

... may the RUBY lessons continue ....

**** edit ***
strange ... just tried to DL and load this file ... now showing a Ruby error

[RJHollins]

small step forward

To the code I posted above, I added this Ruby line:

Code: Select all

output 0,@found.join(",")

I believe this is what NuBeat was referring to ?!?

his now give an output in this form:

Code: Select all

Wind Chimes,32

If I could stay within RUBY ... I'd like to be able to output each side of the ',' to a separate output [arrays], while still maintaining this 'clean' format.

Maybe I'm making this more difficult than it need be I've been known to complicate

help
