psl-make-dafsa - Man Page

generate a compact and optimized DAFSA from a Public Suffix List


psl-make-dafsa [options] infile outfile


psl-make-dafsa produces C/C++ code or an architecture-independent binary object that represents a Deterministic Acyclic Finite State Automaton (DAFSA) from a textual representation of a Public Suffix List.  Input and output files must be specified on the command line.

This compact representation enables optimized queries of the list, saving both time and space when compared to searches of human-readable representations.


The format of the data read and written by psl-make-dafsa depends on options passed to it.


cxx: (default) output is C/C++ code
cxx+: output is C/C++ code plus statistical assignments (used by libpsl build process)
binary: output is an architecture-independent binary format


utf-8: (default) UTF-8 mode (output contains UTF-8 + punycode)
ascii: (deprecated) 7-bit ASCII mode (output contains punycode only)
