README.md

This directory contains a single source file, mlr.bnf, which is the lexical/semantic grammar file for the Miller put/filter DSL using the GOCC framework. (In a classical Lex/Yacc framework, there would be separate mlr.l and mlr.y files; using GOCC, there is a single mlr.bnf file.)

All subdirectories of src/parsing/ are autogen code created by GOCC's processing of mlr.bnf. They are nonetheless committed to source control, since running GOCC takes quite a bit longer than the go build mlr.go does, and the BNF file doesn't often change. See the top-level miller/go build scripts for how to rerun GOCC. As of this writing, it's bin/gocc -o src/parsing src/parsing/mlr.bnf as invoked from the miller/go base directory.
