=head1 NAME
|
|
|
|
includemocs -- handle mocifyable headers, whose .moc file is nowhere included.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
includemocs
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Header files declaring a QObject descendant have to be run through moc to
|
|
produce a .moc file. This .moc file has to be compiled, for which two
|
|
possibilities exists: compile it separately, or #include it in the C++ file
|
|
implementing that above mentioned class. The latter is more efficient in term
|
|
of compilation speed.
|
|
|
|
This script searches in the current directory and its subdirs for header files
|
|
declaring a QObject descendant class. If it finds some, it looks, if there is
|
|
a C++ file containing an '#include' for the generated .moc file. If thats not
|
|
the case, it tries to guess into which C++ file that '#include' is placed best
|
|
(based on the filename). If it fails to guess a proper place, it mentions
|
|
that.
|
|
|
|
On stdout commands are ouput, suitable for a shell, which, when
|
|
evaluated, add the suggested '#include' at the end of the files.
|
|
|
|
On stderr some informational messages are printed.
|

=head1 EXAMPLES
|
|
|
|
cd kdebase ; includemocs
|

cd kdebase ; `eval includemocs 2> /dev/null`
