rexgen

A tool to create words based on regular expressions.

Requirements

To build rexgen, you'll need the following tools and libs:

Tool	needed for
flex	Generator for lexical analysis of regular expressions
bison	Generator of parser for regular expressions
cmake	Creation of Makefiles
clang	Compiling the code

On Ubuntu, you can install these via e.g.

sudo apt install flex libfl-dev libbison-dev cmake clang bison

Building rexgen

Clone the git repository to include the required FindICU:

git clone https://github.com/janstarke/rexgen.git

Build and install:

cd rexgen
./install.sh
# you can use the switches -p to enable python support and -l to enable lua support

Problems

If you have problems building rexgen, you can change to the build directory and run cmake .. && make manually. Currently supported options for rexgen's CMakefile are:

-DCMAKE_BUILD_TYPE=Debug creates a debug build
-DUSE_PYTHON=On tells cmake to include the python interface
-DUSE_LUA=On tells cmake to include the lua python interface

Using the C++ API

rexgen::RexgenOptions options;
auto regex = parse_regex("Test[0-9]", options);
assert(regex != nullptr);

auto iter = std::make_shared<rexgen::TopIterator>(regex);

SimpleString str;
while (iter->next()) {
    str.clear();
    iter->value(&str);
    std::cout << str.c_str() << std::endl;
}
