Hi.
I'm a newby in this Forum and in Ruby, but I want give my contribution.
class Array
alias oldJoin join
def join(sep='')
res=self
res=self.map {|el| yield el} if block_given?
res.oldJoin(sep)
end
end
What you things about-it?
Thank in advance, for any comments.

x = 10
x = 20
puts x
What is the output? Would the code produce a different result if the
first assignment statement was commented out?

I'm looking for suggestions on how I might parse this data.
addrmap_ntimc0 = insFld(foldersTree, gFld("ntimc0 @0x0.0x0.0x0", "ntimc0_doc.html#addrmap_ntimc0"))
addrmap_ntimc0_ntimc_core = insFld(addrmap_ntimc0, gFld("ntimc_core @0x0.0x0.0x0", "ntimc0_doc.html#addrmap_ntimc0_ntimc_core"))
reg_ntimc0_ntimc_core_CFG = insDoc(addrmap_ntimc0_ntimc_core, gLnk("R", "CFG @0x0.0x0.0x0", "ntimc0_doc.html#reg_ntimc0_ntimc_core_CFG"))
…
addrmap_ntimc1 = insFld(foldersTree, gFld("ntimc1 @0x1.0x0.0x0", "ntimc1_doc.html#addrmap_ntimc1"))
addrmap_ntimc1_ntimc_core = insFld(addrmap_ntimc1, gFld("ntimc_core @0x1.0x0.0x0", "ntimc1_doc.html#addrmap_ntimc1_ntimc_core"))
reg_ntimc1_ntimc_core_CFG = insDoc(addrmap_ntimc1_ntimc_core, gLnk("R", "CFG @0x1.0x0.0x0", "ntimc1_doc.html#reg_ntimc1_ntimc_core_CFG"))
What I want to do is group everything starting with the line that includes insFld(foldersTree,
So in this abbreviated data, that would be the first line (addrmap_ntimc0) up to the line prior to (addrmap_ntimc1).
Normally I would use read in the file, assign it to a variable and then use someVariable.split(" insFld(foldersTree,")
However, in this case I want everything from the beginning of that line too. Any ideas? Maybe a different way to parse this data?
Thanks,
Wayne
I am thinking that this version is in no way better than using #map
and #join explicitly. If you want to make this more efficient, you'd
at least have to do something like this
class Array
def join(sep = '', &b)
b ||= lambda {|x| x}
s = nil
each do |e|
if s
s << sep
else
s = ''
end << (b[e].to_s)
end
s
end
end
I am not sure though that this is such a great idea because you can
usually do this via #inject.
Kind regards

For a very simple ugly solution, you could use a regex with lookahead.
someVariable.split(/(?= insFld\(foldersTree,)/)
This would essentially split before every occurence (as the match itself would be zero-width; the contents of lookahead expression are not matched, only its "presence").

Not better. Only simpler...

Well, Thanks you very much for explanation and details.

Close… What this gets me is:
insFld(foldersTree, gFld("ntimc0 @0x0.0x0.0x0", "ntimc0_doc.html#addrmap_ntimc0"))
addrmap_ntimc0_ntimc_core = insFld(addrmap_ntimc0, gFld("ntimc_core @0x0.0x0.0x0", "ntimc0_doc.html#addrmap_ntimc0_ntimc_core"))
reg_ntimc0_ntimc_core_CFG = insDoc(addrmap_ntimc0_ntimc_core, gLnk("R", "CFG @0x0.0x0.0x0", "ntimc0_doc.html#reg_ntimc0_ntimc_core_CFG"))
…
reg_ntimc0_cfg_node_node_scratch = insDoc(addrmap_ntimc0_cfg_node, gLnk("R", "node_scratch @0x0.0xff.0x20", "ntimc0_doc.html#reg_ntimc0_cfg_node_node_scratch"))
addrmap_ntimc1 =
What I also need the start of the line (in this case addrmap_ntimc0 = & the addrmap_ntimc1 would belong to the next capture array item.)
I struggled with this for a while and couldn't come up with a great solution. I'm hoping somebody here would have an easy fix for me. 
I'll sleep on this and see what I can come up with tomorrow AM.
Thanks Matma!

Something like this?

"ntimc0_doc.html#addrmap_ntimc0"))

EOF
data.lines.each do |l|
(lval,rval) = l.strip.split(/\s*=\s*/)

(gmail's line folding will probably mess that up, so here's a gist:

Thanks tamouse and Matma. In the end I cheated. While certainly not pretty, or efficient , I opted for a two-pass read. First time through I look for a match of the "insFld(foldersTree, gFld", then I simply added ### to the beginning of the line and replaced that in my array. During the next read I simply split on the three hash symbols. It's so much easier to split knowing what is at the beginning of a section, than text in the middle. 
Thanks again to both of you.
