Compiling the generator
=======================

You need:
 - The clang libraries version 3.1 or later (e.g. pre-3.2)
 - A recent C++ compiler (tested with clang 3.1 and gcc 4.7 on Linux)

You may optionaly apply the patch in the patches/ directory to clang
for better performances. (Note: the patch breaks binary compatibility!)


Example:
cmake . -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DLLVM_CONFIG_EXECUTABLE=/opt/llvm/bin/llvm-config -DCMAKE_BUILD_TYPE=Release
make
# because clang searches for includes files in ../lib relative to the executable: 
ln -s /opt/llvm/lib/ .  


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


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. You use those arguments:
 -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 comas
 
Step 3: Generate the index HTML files using codebrowser_indexer

By running the codebrowser_indexer with the path to the generated html as 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
 git ls-files | egrep "\.cpp$" | xargs ./generator/codebrowser_generator -b $PWD -p codebrowser:$PWD:`git describe` -o ~/public_html/codebrowser
 ./indexgenerator/codebrowser_indexgenerator ~/public_html/codebrowser
 ln -s ./data ~/public_html/
 
Step 5: Open it in a browser or upload it to your webserver
