1. Ports depends one from one.
In general port X depend from port Y ==> X is not valid without Y.
But exists many cases, in which port X particulary depending from Y.
It means, that some subparts of X is not valid without Y.
for example:
simpack particulary depend from tk4.{1,2}
(as it have sdsmt)
noweb particulary depend from teTeX or tex-3.1415
(as it have noweb.sty: LaTeX style)
gnats particulary depend from emacs/xemacs
(as he have send-pr.el)
I want introduse that:
*ports X linkable with port Y, if X have additional feautures, which
work if Y is installed*
I want to have such ports system, which allow install X, than install
Y.
How to do it:
let we have structure, such as windows registry, wher we holds
"port-lincable" ports and actions.
Example:
TeX
CONCEPT : STYLE_DIRECTORY
ACTIONS : LINK_STYLE = ln $1 $STYLEDIRECTORY
teTEX
CONCEPT : STYLE_DIRECTORY=/usr/ports/teTeX/tex/texfmts
SHELL_VARIABLES: TETEXROOT=/usr/ports/teTeX.
ACTIONS : LINK_STYLE=action(TEX,LINK_STILE);tetexhash
tex-3.14.25
.........
in teTeX port MAKEFILE:
or may be in teTeX/pkg/ports-registry
PORTS_REGISTRY_TOP_KEY=TeX
PORTS_REGISTRY_CONCEPTS="STYLE_DIRECTORY=${PREFIX}/teTeX/tex/texfmts"
PORTS_REGISTRY_SHELL_VARIABLES="TETEXROOT=${PREFIX}/teTeX"
PORTS_REGISTRY_ACTIONS="LINK_STYLE=action(TeX,LINK_STYLE);tetexhash"
in noweb port Makefile: (or pkg/ports-registry)
PORTS_REGISTRY_LINK_DEPEND="action(TEX,LINK_STYLE) ${PREFIX}/noweb.sty"
And in /etc/daily we can run programm, which see:
if new ports added ?
if they have ACTIONS ?
if we have ports with ACTIONS_LINK_DEPEND from it ?
do this actions.
2. During boot, we can read shell variables from ports-registry
to initial shell.
(Many ports want to have it's own variables.)
In principle, I can start to write such application, which can work
independed from other system code.
