Extension rbz maker

[driven]

1: open "Ruby Console"
2: paste in this

Gem.install "rubyzip"

and enter...
3: if no errors paste in this

require("zip")
#EDIT; had rubyzip

and enter...
4: if no errors, try this plugin...

or report back...

[TNTDAVID]

thank you

require ('zip') worked well

I can now run Extension RBZ maker !

My plugin does not contain files Skb but SKP.

I noticed that the ruby script codes are protected but not the components used by my Plugin.

Is there a way to protect the SKP files ?

your image above shows both in the folder

No, even if there was, once it's in the model people can do anything they want...

I downloaded the file rubyzip2-2.0.2.gem

Do not use that. It is actually an older code fork than just plain rubyzip v1.1.6.

(Not sure why the author left it up on rubygems.org. It is a kind of beta version for Ruby higher than 1.8, but was abandoned. The original v1 code trunk was fixed to run in 1.9+ Ruby.)

@dan what's happening with require 'rubyzip' v require 'zip' ?

The RubyGems extension modifies the global require() method so that it can load gems (and push their paths into $LOAD_PATH,) and if need be, install them first from whatever gem servers are registered. (By default only rubygems.org is registered.)
So [important], this: require 'rubyzip', is actually saying "require the gem named 'rubyzip'", not "require the file named 'rubyzip.rb'".

Once the gem library is installed and loaded, it can be used as it normally would, had it been a standard extension, in Ruby's library.
Hence, the require("zip") which actually makes sure that the
"#{ENV['GEM_PATH']}/gems/rubyzip-v1.1.6/lib/zip.rb" file is loaded.
This works because the override of the global require(), by the RubyGems extension, has push the rubyzip lib into the $LOAD_PATH array. Ie:
"#{ENV['GEM_PATH']}/gems/rubyzip-v1.1.6/lib/"

But I like to wrap in begin. .. rescue, just in case.

cheers dan,
another ?
in your example code wont require 'rubyzip' always fail, even when require 'zip' returns true?

Hmmm.. OH I see.. even though, given the following:
Ref:

@unknownuser said:

When RubyGems is required, Kernel#require is replaced with our own which

is capable of loading gems on demand.

When you call require 'x', this is what happens:

* If the file can be loaded from the existing Ruby loadpath, it is.

* Otherwise, installed gems are searched for a file that matches.

If it's found in gem 'y', that gem is activated (added to the

loadpath).

The normal require functionality of returning false if

that file has already been loaded is preserved.

Something I overlooked was, that in most gems, the gem "name" is the same as the gem loader script name.

But in this gem, the name is "rubyzip", but the loader script name is "zip.rb".

So what the overridden require does is, look for a loader script named "rubyzip.rb" and it will NEVER find it, so a LoadError exception will be raised, always, even if the gem is already installed, and even if it is already loaded.

And then my rescue LoadError clause will be fired.

This doesn't hurt the first time, as if SketchUp is started normally and Rubygems is loaded and working.. the "rubyzip" gem will get installed and/or initialized by my LoadError clause.

OK I need to change things a bit. I used to have a bail out " return true if defined?(Zip)" as the first line, removed it when I tried to load the "zip/filesystem" extension in the same methoid. I moved that to it's own method, so I'll put the short-circuit return line back in.

Then I may need a different basic test other than require("rubyzip").
I am not actually using the return value of require("rubyzip") to make any boolean decisions.
Perhaps just require("zip") ?

I want to blur my fichiers.rb to protect my work, so I downloaded the Plugin BGSketchup_RBZ_maker v1.0.1.rbz

RBZ-files are not intended to protect code. Any unzip program can be used the convert them back to the original files.
Only the scrambler will give limited protection.

[TNTDAVID]

pgarmyn

I can assure you that RBZ maker convert my file "rb" in "rbs" !

Although the RBZ file can be decompressed the code is protected

driven

You're right for the skb! This is fixed now

[TNTDAVID]

I just noticed a very annoying problem !

RBZ maker produces non-compatible files rbs with Sketchup 8
I think many users are still under licenses "Sketchup 8" and wishes propose a PLUGIN which works for a maximum of users.

Is there an alternative to produce rbs files ?

[driven]

what's the error message on v8 say?

I'd be surprised if the .rbs is unusable, does it run as a .rb on the same machine?

have DC's been enabled on that machine?

Make sure your files are UTF-8 Encoded Without BOM.

[TNTDAVID]

There is no error message the launch of Sketchup !

Error 01: The toolbar will no longer display the images on the icons.

Error 02: The relationship between icons and components is lost.

[driven]

are you still using

 path_to_components = File.join(File.dirname(__FILE__), 'Components')

I'm unsure if that works from inside a rbs, I remember there was some problem with it...

[TNTDAVID]

Yes ! So how can I do otherwise ?

[driven]

It's hard without knowing your folder structure...
once installed from rbz
you should have a plain 'extension' .rb file and a same name folder...
inside the folder you should have a plain .rb 'loader' file
that loads the .rbs file
plus any other folders...

is that how it is set up?
post a screen shot of the folder structure...

is this now the rbs that's failing?
if so you need another .rb

ClickChange
--------ClickChange_loader.rb
--------ClickChange_logic.rbs
....etc

the minimum ClickChange_loader.rb needs to do is require('ClickChange_logic'), but it may be a little more involved than that...

I never encrypt any files, so this is from remembering other threads...

(1) You need to use author namespace and file/folder prefix.
[Assuming the Ruby namespace TNT has not been used by anyone else...]
ie (in "Plugins" folder): [pre:2sn8ckc3]TNT_ClickChange.rb
TNT_ClickChange/ClickChange_loader.rb
TNT_ClickChange/ClickChange_logic.rbs
TNT_ClickChange/Components
TNT_ClickChange/Resources[/pre:2sn8ckc3]

(2) Then the %(#400080)[Plugins/TNT_ClickChange.rb] file:

(4) Your %(#400080)[TNT_ClickChange/ClickChange_logic.rbs] file needs to be defined inside the nested TNT::ClickChange namespace, and use the local constants DIR_ABS and DIR_REL.
