# This script generates PHP lexer and parser files required to build PHP. The
# generated files are ignored in the Git repository and packaged during the PHP
# release process into the release installation archive download. This way the
# bison and re2c dependencies are not required to build PHP when downloading
# release archive.
#
# Usage: genfiles
#
# Environment:
# The following environment variables can override default generators paths.
#
# YACC Parser generator program, default bison
# RE2C Lexer generator program, default re2c
# SED Path to sed program, default sed
# MAKE Path to make program, default make
#
# For example:
# YACC=/path/to/bison ./genfiles
YACC=${YACC:-bison}
YACC="$YACC -l"
RE2C=${RE2C:-re2c}
RE2C_FLAGS="-i"
SED=${SED:-sed}
