\textit{Nail} is an interface generator that allows programmers to safely parse and generate protocols defined by a Parser-Expression based grammar. Nail also provides solutions for parsing common patterns such as length and offset fields within binary formats that are hard to process with existing parser generators.
The code generator (in /generator/) requires a C++ compiler and depends on boost. The code generator can either be invoked as ./nail foo.nail , which case it will emit C++ code (in foo.nail.cc and foo.nail.hh) , or as ./cnail foo.nail in which case it will emit a two-pass parser in C (in foo.nail.c and foo.nail.h) . Generated code has no dependencies (and does not even use the C++ or C standard library). longjmp.h/setjmp.h is used for handling out of memory errors.
Several examples are provided, pull requests for more are very welcome!
- /dns - DNS server and resolver implemented in C. Used for older benchmarks
- /dns_cpp - DNS server implemented in C++, used for newer benchmarks
- /zip - ZIP extractor,compressor in C.
- /protozip - Simplified 'pretend' zip, easier to grok
- /utf16 - mini grammar for UTF-16 -- good starting point
Nail has a (very prototype-y) network stack. Find it in /network/. The network stack depends on boost and (soon) Intel TBB and DPDK .
