It uses doxygen to generate the API documentation. For each subsystem a very small (about 20 lines with comments) subsystem specific Doxyfile has to be written (have a look at the README for more). All common doxygen options are specified in a separate file. The framework is configured to not only generate the HTML version, but also a PDF version (the paper size is hardcoded to DIN A4 currently and depending on the subsystem you have to increase some limits in the latex configuration of your system, the README tells more about this). It also allows cross-references between the subsystems (it generates doxygen tag files). Currently the docs are generated in OBJDIR, but this may change after coordination with doc@. The makefile is prepared to generate/move various parts of the generated docs to different destinations. TARGET_ARCH is respected and some env-vars are set for architecture specific handling of the source (the README tells more). Subsystems for which docs are generated: - cam - crypto - dev_pci - dev_sound - dev_usb - geom - i4b - kern - libkern - linux - net80211 - netgraph - netinet - netinet6 - netipsec - opencrypto - vm Requested by: gnn

--------------------------------------------------------------
|
|
|
|
For every Doxyfile-(.*) the Makefile adds the public targets $1, pdf-$1 and
|
|
clean-$1. For e.g. Doxyfile-dev_pci this translates to the targets dev_pci,
|
|
pdf-dev_pci and clean-dev_pci.
|
|
|
|
Additionally, the targets 'all', 'pdf-all' and 'clean' to generate or remove
|
|
the documentation for all targets are available.
|
|
|
|
The file 'Dependencies' contains dependencies for the .tag files.
|
|
|
|
To add another part to the documentation just copy a Doxyfile and add
|
|
the necessary dependencies to the file 'Dependencies'.
|
|
|
|
The following environment variables can be used in the Doxyfile:
|
|
- DOXYGEN_SRC_PATH (/usr/src/sys)
|
|
- DOXYGEN_DEST_PATH (where the docs are generated)
|
|
- DOXYGEN_TARGET_ARCH (${TARGET_ARCH} if set, else ${MACHINE_ARCH})
|
|
|
|
For the PDF generation you may have to change some limits in the latex
|
|
configuration (the build may fail and an error about e.g. "pool size" is
|
|
shown), for print/teTeX this is done in
|
|
/usr/local/share/texmf/web2c/texmf.cnf
|
|
|
|
Programs needed to generate the API docs:
|
|
- devel/doxygen
|
|
- print/teTeX
|
|
- graphics/graphviz
