Ruby namespace best practice.

[Walter Sommerfeld]

Hmm,

did i miss something?

when i open ur

Simple Class Door.fsm

i always get the error:

NoMethodError: undefined method 'open?' for
#<Trog::Door:0xa9a74f0 @open=false

[trogluddite]

Yes, that's right - I was demonstrating why Tronic's 'class method' style call would not work for an instance method - as in the comments...

Code: Select all

# Trog::Door is a class, not a Door!

[Walter Sommerfeld]

I understood... but even now?

[trogluddite]

Aaah - now I see!
Didn't read my own API docs! - the correct method is, of course "is_open?" not plain old "open?" - D'oh!

[Walter Sommerfeld]

No prob -

i knew there must be a typo or...

ruby is 2 new 4 me - especially even w/o gems and some standard libs missing!

Even version conflicts/bugs inside ruby and the 'perfecto' editor in FS makes it more difficult 4 a beginner...

Keep on doing!

P.S: got an access denied error - damn where is that monster coming from (different schematic btw.)

P.S: got an access denied error

What are you tying to access that it won't let you?

[Walter Sommerfeld]

It was a:

'Dir.mkdir(temp_subfolder_name) unless File.exists?(temp_subfolder_name) # make folder if not exist'

i changed it into this:

if File.directory?(temp_path) #sun mod 20130503
#do nothing
#watch 'temp_path exist', temp_path
else
#watch 'temp_path_dont exists', temp_path
Dir.mkdir(temp_subfolder_name) unless File.exists?(temp_subfolder_name) # make folder if not exist
end
