Release pacc-0.3
A new stable release is now available. Users of Fedora, CentOS, or RHEL can now install this release from a copr. Of course, the development source is still available from github and gitlab.
pacc is a compiler-compiler, somewhat like yacc (or bison). Its input is a description of a grammar, and its output is a C function that recognizes strings of that grammar. The significant technical difference is this: yacc reads a context-free grammar (CFGs), and writes a LALR(1) parser; pacc reads a parsing expression grammar (PEG), and writes a packrat parser.
PEGs and packrat parsing offer several advantages over CFGs.
The current stable release is pacc-0.3 (bugyō) under the GPL. This is a beta release, see the TODO list for further information. The intention is that pacc will mature to be an industrial-strength parser-generator.
The name pacc is a recursive acronym: pacc: a compiler-compiler. Needless to say, pacc's own parser is written in pacc.

One thing pacc needs is more users. And, perhaps, one way to get more users is to reduce the friction in getting started with pacc. An obvious lubricant is packaging. Read More...
Looking at _pacc_coords(), I noticed that it seemed to have the same realloc() bug that I'd just fixed in _pacc_result(). However, the "list of arrays" trick really wasn't going to work here. Read More...
