A small C++ library that implements almost complete LDAP Search Filter grammar as defined in RFC 2254 and a search facility inside a vector of key-value mapped data.

Features:

• Formal Search Filter BNF grammar using header-only boost::spirit library. Extensible filter grammar is not implemented.
• The parser supports Unicode and hex-encoded Unicode rules.
• The search facility makes use of the ICU internationalization library with adjustable collation levels which allows searching data in a non-strict way when case and diacritics are ignored.

There is a test example inside sub-directory test/ showing how to use the library. In this example, data is read from a JSON file records.json. This requires linkage against jsoncpp library. To compile the example, run

g++ -std=c++11 -o test test.cpp -lldapsf -ljsoncpp

in a terminal. The data records in the test file contain UTF-8 encoded samples of key-value maps with Russian names, surnames and optional grades and extra marks. Inside the source code of test.cpp a search filter is created to show how the ldapsf library can be used. Run the test with command

./test
