How to construct a complete plugin using the emacs skeletons
0. Install open-vpp, including the development package.
1. Load emacs skeletons
M-x find-file all-skel.el
M-x eval-buffer
2. Pick a single-word, lower-case name for your plugin. For example: macswap.
Hereafter, we'll refer to the selected name as <plugin-name>.
3. Generate the entire plugin:
M-x make-plugin
Plugin-name: <plugin-name>
Or, generate each file individually:
3. Create the required directories, e.g. under .../vpp
$ mkdir -p <plugin-name>-plugin/<plugin-name>
4. Create <plugin-name>-plugin/{configure.ac,Makefile.am}
M-x find-file <plugin-name>-plugin/configure.ac
M-x plugin-configure-skel
M-x find-file <plugin-name>-plugin/Makefile.am
M-x skel-plugin-makefile
5. Create the api skeleton
M-x find-file <plugin-name>-plugin/<plugin-name>/<plugin-name>.api
M-x skel-plugin-api
6. Create the api message enumeration header file
M-x find-file <plugin-name>-plugin/<plugin-name>/<plugin-name>_msg_enum.h
M-x skel-plugin-msg-enum
7. Create the "all-api" header file
M-x find-file <plugin-name>-plugin/<plugin-name>/<plugin-name>_all_api_h.h
M-x skel-plugin-all-apih
8. Create the main data structure definition header file
M-x find-file <plugin-name>-plugin/<plugin-name>/<plugin-name>.h
M-x skel-plugin-h
9. Create the plugin main C file
M-x find-file <plugin-name>-plugin/<plugin-name>/<plugin-name>.c
M-x skel-plugin-main
10. Create the vpp-api-test plugin main C file
M-x find-file <plugin-name>-plugin/<plugin-name>/<plugin-name>_test.c
M-x skel-plugin-test
11. Create the data plane packet processing node
M-x find-file <plugin-name>-plugin/<plugin-name>/node.c
M-x skel-plugin-node
12. Process autotools input files
$ cd <plugin-name>-plugin
$ autoreconf -i -f
13. Build the plugin skeleton
$ mkdir build
$ cd build
$ ../configure
$ make
$ sudo make install
