This is the generator for the woboq code browser.

See http://code.woboq.org for an example.

Introduction and Design

There is a pre-processing step on your code that generates static html and reference database. The output of this phase is just a set of static files that can be uploaded on any web hoster. No software is required on the server other than the most basic web server that can serve files.

While generating the code, you will give to the generator an output directory. The files reference themselves using relative path. The layout in the output directory will look like this: (Assuming the output directory is ~/public_html/mycode)

$OUTPUTDIR/../data/ or ~/public_html/data/ is where all javascript and css files are located.

$OUTPUTDIR/projectname or ~/public_html/mycode/projectname contains the generated html files for your project

$OUTPUTDIR/refs or ~/public_html/mycode/refs contains the "database" used for the tooltips

$OUTPUTDIR/include or ~/public_html/mycode/include contains the generated files for the files in /usr/include

The idea is that you can have several project sharing the same output directory. In that case they will also share references and use searches will work between them.

Compiling the generator on Linux

You need:

The clang libraries version 3.4 or later

Example:

cmake . -DLLVM_CONFIG_EXECUTABLE=/opt/llvm/bin/llvm-config -DCMAKE_CXX_COMPILER=/opt/llvm/bin/clang++ -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DCMAKE_BUILD_TYPE=Release
make

If you have errors related to exceptions, edit generator/CMakeLists.txt and replace -fno-rtti by -fexceptions

Compiling the generator on OS X 10.9 Mavericks

You need:

The clang libraries, for example in version 3.3
XCode 5.x and the command line tools and includes

Install XCode and then the command line tools:

xcode-select --install

Install the clang libraries via homebrew ( http://brew.sh/ ):

brew tap homebrew/versions
brew install -vd llvm33  --with-libcxx --with-clang --rtti

Then compile the generator:

cmake . -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DLLVM_CONFIG_EXECUTABLE=/usr/local//bin/llvm-config-3.3  -DCMAKE_BUILD_TYPE=Release
make

Using the generator

Step 1: Generate the compile_commands.json for your project

The code browser is built around the clang tooling infrastructure that uses compile_commands.json http://clang.llvm.org/docs/JSONCompilationDatabase.html If your build system is cmake, just pass -DCMAKE_EXPORT_COMPILE_COMMANDS=ON to cmake to generate the script. For other build systems (e.g. qmake, make) you can use scripts/fake_compiler.sh as compiler (see comments in that file)

Step 2: Create code HTML using codebrowser_generator

Before generating, make sure the output directory is empty or does not contains stale files from a previous generation.

Call the codebrowser_generator. See later for argument specification

Step 3: Generate the index HTML files using codebrowser_indexer

By running the codebrowser_indexer with the output directory as an argument

Step 4: Copy the data/ directory one level above the generated html

Example: To generate the code for this project itself:

cmake . -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
./generator/codebrowser_generator -b $PWD -a -o ~/public_html/codebrowser -p codebrowser:$PWD:`git describe --always --tags`
./indexgenerator/codebrowser_indexgenerator ~/public_html/codebrowser
ln -s ./data ~/public_html/

Step 5: Open it in a browser or upload it to your webserver

Note: By default, browsers do not allow AJAX on file:// for security reasons. You need to upload the output directory on a web server, or serve your files with a local apache or nginx server. Alternatively, you can disable that security in Firefox by setting security.fileuri.strict_origin_policy to false in about:config (http://kb.mozillazine.org/Security.fileuri.strict_origin_policy) or start Chrome with the --allow-file-access-from-files option.

Arguments to codebrowser_generator

codebrowser_generator -a -o <output_dir> -b <buld_dir> -p <projectname>:<source_dir>[:<revision>] [-d <data_url>] [-e <remote_path>:<source_dir>:<remote_url>]

-a process all files from the compile_commands.json. If this argument is not passed, the list of files to process need to be passed

-o with the output directory where the generated files will be put

-b the "build directory" containing the compile_commands.json

-p (one or more) with project specification. That is the name of the project, the absolute path of the source code, and the revision separated by colons example: -p projectname:/path/to/source/code:0.3beta

-d specify the data url where all the javascript and css files are found. default to ../data relative to the output dir example: -d http://code.woboq.org/data

-e reference to an external project. example:-e llvm/tools/clang/include/clang:/opt/llvm/include/clang/:http://code.woboq.org/userspace
