Stop processing rest of file?

Dan Rathbun

So far I am trying my best to NOT touch or override either require or load themselves.

tbd

have a separate loader.rb that checks if LIB exists and has functions required.
if yes, require/load rest of your code, if not ...

Having to have yet ANOTHER file for each and every library or plugin package, is not what I am aiming at...

... besides that does not solve the idiot situation, trying to force a plugin to load, using load(), when require does not work.
I'm not sure there is a solution to the idiot syndrome anyway. I (personally,) would not give any support, or waste any time responding, to an idiot who does not let the plugin load the way it's supposed to.

ThomThom, for now do something like:

module TT_FancyUtil

  # move require dependancy calls inside namespace
  require('TT/TT_Lib2') rescue raise(LoadError,'TT_Lib2')
  require('TT/TT_GUI') rescue raise(LoadError,'TT_GUI')

  # the rest of the module's code

# way down the bottom of the namespace block;
rescue LoadError => e

  case e.message
  when 'TT_Lib2'
    puts("LoadError; TT_Lib2 file is not present. .. blah blah blah...")
  when 'TT_GUI'
    puts("LoadError; TT_GUI file is not present. .. blah blah blah...")
  else
    puts("Error; #<#{e.class.name}; #{e.message}>")
    puts e.backtrace
  end

end # module

Really don't want to use another file. Many of my plugins are self contained in a single file - apart from that they require TT_Lib. And I don't want to split it up just for this check.

Found a way:

<span class="syntaxdefault">require </span><span class="syntaxstring">'sketchup.rb'<br /></span><span class="syntaxdefault">begin<br />  require </span><span class="syntaxstring">'TT_Lib2/core.rb'<br /></span><span class="syntaxdefault">rescue LoadError </span><span class="syntaxkeyword">=></span><span class="syntaxdefault"> e<br />  </span><span class="syntaxcomment"># meh!<br /></span><span class="syntaxdefault">end<br /><br />module MagicPlugin<br />  </span><span class="syntaxcomment"># Voodoo<br /></span><span class="syntaxdefault">end if defined</span><span class="syntaxkeyword">?(</span><span class="syntaxdefault"> TT</span><span class="syntaxkeyword">;;</span><span class="syntaxdefault">Lib </span><span class="syntaxkeyword">)<br /></span><span class="syntaxdefault"> </span>

interesting!

Hmm ... I see rescue modifiers do not work with require(), for some reason ?

You could also do (if you did not want any module defined) ...

require 'sketchup.rb'
begin
  require 'TT_Lib2/core.rb'
rescue LoadError => e
  # meh!
else
  module MagicPlugin
    # Voodoo
  end
end# begin

What you mean? What modifiers?

tbd

statement modifiers = conditional statements onto the end of a normal statement

` name = first_name + last_name rescue "John Doe"

John Doe # if first_name and last_name are not defined`

The conditional keywords if and unless can be used in block position:
[ if| unless] ( expression)
statements
end

or modifier position:
statement [ if| unless] ( expression)

**rescue** can also be used in modifier poistion, but ... my attempt at this:
require('booboo.rb') rescue nil
... does NOT trap the LoadError (because LoadError < ScriptError < Exception, and rescue only traps RuntimeError and subclasses by default.)

For a one-liner, we must use semi-colons:
begin require('booboo.rb'); rescue Exception; nil; end
