octave: PKG_ADD and PKG_DEL Directives
37.4.3 PKG_ADD and PKG_DEL Directives
-------------------------------------
If the package contains files called ‘PKG_ADD’ or ‘PKG_DEL’ the commands
in these files will be executed when the package is added or removed
from the users path. In some situations such files are a bit cumbersome
to maintain, so the package manager supports automatic creation of such
files. If a source file in the package contains a ‘PKG_ADD’ or
‘PKG_DEL’ directive they will be added to either the ‘PKG_ADD’ or
‘PKG_DEL’ files.
In ‘m’-files a ‘PKG_ADD’ directive looks like this
## PKG_ADD: some_octave_command
Such lines should be added before the ‘function’ keyword. In C++ files
a ‘PKG_ADD’ directive looks like this
// PKG_ADD: some_octave_command
In both cases ‘some_octave_command’ should be replaced by the command
that should be placed in the ‘PKG_ADD’ file. ‘PKG_DEL’ directives work
in the same way, except the ‘PKG_ADD’ keyword is replaced with ‘PKG_DEL’
and the commands get added to the ‘PKG_DEL’ file.
