Marking Tcl/Tk code

A string, for example "hello world" is set to be translated by calling a special function, named _ for GiD strings, and = for problemtype strings.
To call this function must enclose it with [ ], for example:
[_ "Hello Word"] for a GiD script, or [= "Hello Word"] for a problemtype script
For a problemtype the source code is scanned to find [= ] instead [_ ]


It's possible to add to the string some special format % characters
set numfiles 3 [_ "Copied %d files" $numfiles] If the source and the translated strings have different % format, the program using this translation can crash at runtime. To avoid thid situations there is menu:
Messages -> Check format
To search inconsistent (in format) translated sentences.
For example it's a bug to translate the sentence "Copied %d files" to "Copiados %f ficheros", because %d expect an integer, and %f expect a real number.
