I have developed about 300 Applications which I would like to provide with multi-language capabilities independent from the Operating System. I have written a just-in-time translator, but that is too slow in applications with many components. What would you suggest I do?
I’ve heard that the TsiLang components are nice, but your looking at an inplace solution…
I’ve used GNU gettext for Delphi which does exactly the thing you want, it loads the translations from a text file and replaces the text in your components. It even has a pas/dfm scanner to automatically generate the English translation file.
It’s also possible to automatically change your pascal source code to inject the gettext procedure inplace of your static strings. If I’m not mistaken it just adds a underscore as function to it, as below.
I must say it has been 2 years since I last used this method.
One thing will remain problematic, the Delphi components are not unicode enabled (D2009 fixes this), so when you don’t change the components you’ll still have limited support for other languages.
