Procedure be followed in Tcl / Tk
The strings to be translated must be marked with the procedure _
Typically, to run it must be enclosed in square brackets: (this procedure is called at runtime, there is no pre-compilation)
In the case of being a "ProblemType" of GiD, instead of _ you have to use =, to be able to differentiate both environments.
For example:
set to "hello world"
For GiD you should write:
set a [_ "hello world"]
and for a "ProblemType":
set to [= "hello world"]
Note: it is essential that there is one or more spaces between _ and the string.
If the project has been declared as GiD's "ProblemType", instead of tracing strings marked with [_], the ones with [=] will be searched.
The translation of the strings marked with [_] are the responsibility of the GiD team developers, and must not be retranslated by the creator of a "ProblemType",
that is why they are marked differently.
Keywords should not be translated,
For example:
.central.s process "escape geometry create point 3.5 2.8"
It should not be written as:
.central.s process [_ "escape geometry create point 3.5 2.8"]
