po-mode marking
—
Two examples are available in the ‘examples’ directory: ‘hello-tcl’,
‘hello-tcl-tk’.
Before marking strings as internationalizable, substitutions of
variables into the string need to be converted to ‘format’ applications.
For example, ‘"file $filename not found"’ becomes ‘[format "file %s not
found" $filename]’. Only after this is done, can the strings be marked
and extracted. After marking, this example becomes ‘[format [_ "file %s
not found"] $filename]’ or ‘[msgcat::mc "file %s not found" $filename]’.
Note that the ‘msgcat::mc’ function implicitly calls ‘format’ when more
than one argument is given.
