Does "C" equal "C" ?

[MartinRinehart]

Edit: Of course "C" equals "C", (if you don't compound one mistake with another). Got a better way to handle the WebDialog.set_file() issue, which I'll add to that subject's discussion. Otherwise, this was just stupidity that I'll blame on too much snow shoveling.

Back to the WebDialog.set_file() problem. I stumbled across the Ruby File.expand_path() method that looks like a better replacement for the little fixup() function I wrote. If you File.expand_path(__FILE__) you get the full path back to the root, on a Mac, or the drive, on a PC. Perfect!

Except that "C:..." does not equal "C:..." in the following:

# /models/airshow/t.rb

=begin
On a PC, WebDialog.set_file() requires a drive specification.

So you get the working directory; dir = Dir;;pwd()

The working directory will start with;
'/' on a Mac
'C;' (or 'D;' or ...) on a PC

47 == '/'
58 == ';' 

Prefix the given pathname with 'C;' (or 'D;' or ...) unless
    a) you are on a Mac
    b) the given pathname already includes a drive specification
=end
def fixup( pathname )
    dir = Dir;;pwd()
    pathname = dir[0..1] + pathname unless 
        ( dir[0] == 47 ) || ( pathname[1] == 58 )
    return pathname
end

tfile = 'movie_titles.html'

foo = File.expand_path( File.dirname(__FILE__) )
foo = File.join( foo, tfile )
puts foo = 'foo; "' + foo + '"'

bar = fixup( File.dirname(__FILE__) )
bar = File.join( bar, tfile ) 
puts bar = 'bar; "' + bar + '"'

puts 'same? ' + (foo==bar).to_s

try using p str or puts str.inspect instead of puts str to see the exact string including the escape chars.

[thomthom]

what is the intent of the code?

[todd burch]

puts foo = 'foo: "' + foo + '"'
puts bar = 'bar: "' + bar + '"'

Of course they are not the same.

Good idea, tho in this case it wasn't an escape chars issue.

To replace a call to my routine with a better use of Ruby:

# this code works, PC and Mac, any way that __FILE__ was loaded
pathname = File.expand_path( File.dirname(__FILE__) )
pathname = File.join( pathname, 'myFile.HTML' )
wd.set_file( pathname )

Snow-blind coder error.

Back to Uncle Holly stuff ... sigh

Everyone's done it. Yesterday I wrote this as an example:

def = Sketchup.active_model.selection[0].definition

I'm glad that I've nevre mis-typed or mis-comprehended a single line of code, so I don't even begin to comprehend what you guys are talking about

def is a reserved word.

[thomthom]

duh! I would have seen that with syntax highlighting...

WOW, good catch Todd, will you provided your eagle eye services to debug some of my code?

PS: i hope your rates are "reasonable"

[jessejames]

@ Todd it seems that you are actually replying to ThomThom and not Jim and in that context your comment makes sense. The way you quoted it it looked like you where replying to Jim directly so looks like i am the boob here!

If you look back at the original thread, and reread more carefully, you'll see ThomThom told you to use File.expand_path() two weeks before you "stumbled across" it!

I've been wondering why you didn't take his advice... (and do you have a copy of the 'Pick-Axe' Ruby book in chm format?)
