      Changed File: 'pdScript/langLoad.rb', line 32 (and added comment.)

      Will set the hash so that 'key' will be returned, if it is not present as a key.

      I'm not here much anymore.

        Woops.. do not forget to change the version in the _ext file:

        @@extension.version = "1.0.1" or whatever....

        I'm not here much anymore.

          Hello Dan,

          Thanks again for the advises and samples.
          I did what you say, but since you did not post the file format for the language file I tried to understand the source of the parse-function.

          My pdScript_menu.en is this:

          
          pdScript interpreter="pdScript interpreter"
          Adds pdScript interpreter to the ruby environment="Adds pdScript interpreter to the ruby environment!"
          pdScript="pdScript English"
          Start pdScript clock Dialog="Start pdScript clock Dialog English"
          Start pdScript MyDialog Dialog modal="Start pdScript MyDialog Dialog modal English"
          Start pdScript MyDialog Dialog non-modal="Start pdScript MyDialog Dialog non-modal English"
          Start pdScript FreeScript="Start pdScript FreeScript English"
          
          

          The function runs but I get always the key instead of the value.
          What did I miss?

          Regards

          Hans-Peter

            I think I have now the correct format but it still does not work.

            
            "pdScript interpreter"="pdScript interpreter";
            "Adds pdScript interpreter to the ruby environment"="Adds pdScript interpreter to the ruby environment!";
            "pdScript"="pdScript English";
            "Start pdScript clock Dialog"="Start pdScript clock Dialog English";
            "Start pdScript MyDialog Dialog modal"="Start pdScript MyDialog Dialog modal English";
            "Start pdScript MyDialog Dialog non-modal"="Start pdScript MyDialog Dialog non-modal English";
            "Start pdScript FreeScript"="Start pdScript FreeScript English";
            
            

            @@lang = parse_langfile(langpath) # create the language hash
            UI.messagebox(@@lang["pdScript interpreter"])

            does show an empty dialog.

              in File: 'pdScript/langLoad.rb'

              the hash var may be out of scope for the nested blocks. There is some difference between { ... } and do ... end

              I'll try to test later.

              And you can look at any of the strings files in your "Resources/de/" folder. You'll see they have English keys and German values.

              I'm not here much anymore.

                What did I miss?

                because:
                PdScript.module_eval "puts(@@lang.inspect)"
                returns:
                {"pdScript"=>nil, "Adds pdScript interpreter to the ruby environment"=>nil, "pdScript interpreter"=>nil, "Start pdScript clock Dialog"=>nil, "Start pdScript FreeScript"=>nil, "Start pdScript MyDialog Dialog modal"=>nil, "Start pdScript MyDialog Dialog non-modal"=>nil}

                and I created the Hash so that if the value was invalid, it would return the English key as a backup.
                Two problems
                line 74 was chomp! should be chomp

                also, easiest solution for scoping, was to use a instance @ var: @hash instead of hash

                In addition, the keys must be EXACT when you ask for the value, or else you just get the arg returned.

                I corrected the files above

                  You are still using a global var $pdScriptMenuStrings, use a module var instead, like @@pdScriptMenuStrings, or since it will local to your module, an even simplier name, like: @@lang (see below.)

                  Also:

                  1. you did NOT supply the "pdScript.strings" file
                  2. trying to use Google's LanguageHandler class is problematic, because it assumes that the string file is in the Resources subpath (which is difficult to install into.)

                  Instead just have your own "lang" or "strings" subdir, with UTF8 encoded hash files. These files should have extensions that are equal to the user's local language code, thus:
                  langcode = Sketchup.get_locale.split('-')[0] @@extpath = File.dirname(__FILE__) langdir = "lang" langfile = "pdScript_menu.#{langcode}" langpath = File.join(@@extpath,langdir,langfile)

                  So you have a subdir:
                  %(#800080)["pdScript/lang"]
                  that has various string files, like:
                  %(#800080)[pdScript_menu.en] %(#008000)[# English]
                  %(#800080)[pdScript_menu.de] %(#008000)[# German]
                  %(#800080)[pdScript_menu.fr] %(#008000)[# French]
                  etc. etc.
                  A user can copy the english file and resave it with another langcode extension, then edit the values for their own language.
                  Just be sure to test using File.exists?(langpath) and if it returns false, then use the english as a default.

                  It is not really necessary to use a convoluted class like LanguageHandler, when a plain Ruby Hash works just as fine. See the "langhandler.rb" file in the "Tools" dir for the snippet that loads a strings file into a Hash. You can have the hash stored in a simple name like: @@lang and just access the values, like: @@lang["Start pdScript MyDialog Dialog modal"]

                  BUT.. you must also wrap the extension registration script "pdScript_ext.rb" inside your module so that the @@lang var is local to YOUR module, and not Object (which would propagate into everyone else's classes and modules.)

                    Hello Dan,

                    Thanks again.
                    I will add this at the evening.

                    One question again: Is there a save way to gets sketchup's main window handle.
                    I see some posts with winApi calls to search the window by title string.
                    I have done the same in my Dll.
                    Would be nice when Sketchup would publish this in a global var.

                        Hello,

                        I made a small page for the sketchup plugin on my website.
                        I updated the above link for the download.
