13.5.5 AM_XGETTEXT_OPTION in po.m4
The AM_XGETTEXT_OPTION
macro registers a command-line option to be used in the invocations of xgettext
in the po/
directories of the package.
For example, if you have a source file that defines a function ‘error_at_line
’ whose fifth argument is a format string, you can use
AM_XGETTEXT_OPTION([--flag=error_at_line:5:c-format])
to instruct xgettext
to mark all translatable strings in ‘gettext
’ invocations that occur as fifth argument to this function as ‘c-format
’.
See xgettext Invocation for the list of options that xgettext
accepts.
The use of this macro is an alternative to the use of the ‘XGETTEXT_OPTIONS
’ variable in po/Makevars
.
