Moves the random .md files into a config examples tree Change-Id: If423b82f1047f1c84f90876a786313054b5f7c77 Signed-off-by: Chris Luke <chrisy@flirble.org>
2016-09-09Check for zero-sized Graphvix config file on Ubuntu; VPP-396Chris Luke1-1/+2
- The previous change only accounted for a missing Graphviz config file; apparently it can be zero-sized too. Change-Id: Ic6957d10cdc7cb7b9da72d2b2a0f8913100870c5 Signed-off-by: Chris Luke <chrisy@flirble.org>
2016-09-09On Ubuntu check for graphviz system config; VPP-396Chris Luke1-0/+3
- Sometimes it seems Ubuntu doesn't always set up the Graphviz handler config. If it's missing, generate it. https://bugs.launchpad.net/ubuntu/+source/graphviz/+bug/1349026 Change-Id: I2c1e566817de8415f8b360c6f967cd76307a2a52 Signed-off-by: Chris Luke <chrisy@flirble.org>
2016-09-07VPP-221 CLI auto-documentation infrastructureChris Luke7-21/+925
[Note: This is an amalgamation of several patches cherry-picked from master all related to introducing auto-CLI documentation. See commits d4024f58 ee4743ad 16bcf7d8 e0d802bc 54ccf226] As a step before Doxygen, extract CLI-related struct initializers from the code and parse that into a summary of the CLI commands available with the provided help text, such as it is. At the moment this only renders this into an indexed Markdown file that Doxygen then picks up but later we can use this information to enrich the existing VLIB_CLI_COMMAND macro documentor as well as provide runtime documentation to VPP that is stored on disk outside the binary image. Additionally support a comment block immediately prior to VLIB_CLI_COMMAND CLI command definitions in the form /*? ... ?*/ that can be used to include long-form documentation without having it compiled into VPP. Examples of documenting CLI commands can be found in vlib/vlib/unix/cli.c which, whilst not perfect, should provide a starting point. Screen captures of sample output can be seen at https://chrisy.flirble.org/vpp/doxy-cli-example.png and https://chrisy.flirble.org/vpp/doxy-cli-index.png . Next, shift the Doxygen root makefile targets to their own Makefile. The primary reason for this is that the siphon targets do dependency tracking which means it needs to generate those dependencies whenever make is run; that is pointless if we're not going to generate any documentation. This includes the package dependencies since they since they sometimes unnecessarily interfere with the code build in some cases at the moment; later we will look to building a Python venv to host the Python modules we use. One final remark: In future we may consider deprecating .long_help in the VLIB_CLI_COMMAND structure entirely but add perhaps .usage_help. .short_help would be reserved for a summary of the command function and .usage_help provide the syntax of that command. These changes would provide great semantic value to the automaticly generated CLI documentation. I could also see having .long_help replaced by a mechanism that reads it from disk at runtime with a rudimentary Markdown/Doxygen filter so that we can use the same text that is used in the published documentation.

2016-07-26Fix missing include dirs in doxygenChris Luke1-1/+1
Also allow a developer to alter the directories scanned at runtime to facilitate shorter run-times when writing documentation. Change-Id: I2a09519661a3abe1fbc0cfc294000934852af951 Signed-off-by: Chris Luke <chrisy@flirble.org>
2016-07-07Add some doxygen tagsDave Barach1-0/+1

2016-05-16VPP-57 Add missing license headers in doc filesChris Luke1-0/+22

2016-05-15VPP-62 Add a doxy filter to enable vpe.api docChris Luke3-5/+67
This makes Doxygen think the API definitions are structs which is close enough to be able to document the API methods. It also has logic to create an indexed API page but that's disabled for now because it duplicates the "brief" text twice in the struct doc. Fixes a minor line numbering issue in filter_c.py.

2016-05-13VPP-57 Add Doxygen to VPPChris Luke6-0/+2717
- Configures Doxygen. - Adds a source filter to do magic on our use of the preprocessor to do constructor stuff to make Doxygen grok it better. - Adds a convenience helper to the root Makefile. - Adds a README.md to the root directory (and which Doxygem uses as its "mainpage". - Add several other documentative files. - Currently using SVG for call graphs, though this may have a load-time performance impact in browsers.
