{V4Rb2] Console apps

[Charles Yeomans]

I have been having considerable problems getting version 1 databases 
converted to version 2 format. One cause appears to be that I have 
field names like "text" that are reserved words in V4Rb 2.  And I 
wanted to make some other changes to the db format. So I decided to do 
the conversion myself by exporting the v1 database to text files and 
importing the data into a fresh, new v2 database.  The problem was how 
to read the v1 data, since V4Rb 2 cannot read v1 databases except to 
convert to v2, thus bringing me back to the original problem.

My solution was to build a console app using Rb 5.5 and V4Rb1 that 
dumps the database to text.  I include the app in the bundle of the 
main app and call it from a Shell object.  Since the v1 dump is running 
as a separate process, the UI of the main app remains responsive -- 
another bonus.  By using an interactive shell I can write progress 
messages to stdout and thus communicate back to the main app.

The point here is to alert those who might not have thought, as I had 
not, to use Valentina in a console app.  Perhaps other people can find 
more cunning uses for this.
